Industrial reaction kettle
Industrial reactors can be divided into three types according to their structural forms: open (open), closed (closed), and semi-open and semi-closed; according to the heat transfer method, they can be divided into external circulation type, internal circulation type, and direct flow type; according to the heating medium, they can be divided into water-cooled, oil-cooled, and air-cooled jacket heating types. The materials of the reactor were carbon steel, stainless steel, and so on. The process includes putting the materials into the stirring tank for heating and stirring. After reaching the set temperature, close the feeding valve and then open the discharge valve. The materials transfer heat to the cooling tank through the heat exchange and then enter the splitter. The magnetic stirring rod in the splitter is used to clarify the liquid phase. After the liquid phase is filtered, it enters the measuring tank and then is recycled through the return pipe. The concentrated solid particles are processed. When cleaning, open the discharge valve and wash with a high-pressure pump. After checking that there is no problem, it can be put into use. If you need more information about industrial reactors, you can further consult the relevant information. Read more exciting novels for free

Reaction kettle oxygen concentration detection
There were many ways to detect the oxygen concentration in the reactor: 1. ** Sensing ** - ** Limiting-current type micro-oxygen sensor **: For example, the SO-D0 - 020 -A100C limiting-current type Zirconia oxygen sensor recommended by the industry mining website. The range is 0.01% - 2%, the wire length is 1 meter, and the minimum oxygen can be detected is 100pm. It is widely used in metal laser 3D printer, nitrogen production, fermentation and other fields. Its working principle was based on the carrier of the current in the zirconium dioxide bath being oxygen ions. When voltage was applied to the zirconium dioxide bath, oxygen was pumped to the positive pole, and a cover with a hole was added to the negative pole of the bath to limit the rate of oxygen flowing to the negative pole. As the applied voltage increased, the current in the bath reached saturation (limiting current), which was proportional to the concentration of oxygen in the surrounding environment. - ** Phorescent micro-oxygen transmitter **: For example, the UK's SSS fluorescent micro-oxygen transmitter-LOX-Trace- 1000 - BLX can measure the exposure to any oxygen concentration environment without damaging the sensor. It has high oxygen sensitivity and high sensitivity, fast response speed, and short purification time. It can be directly connected to the controller through the RS485 interface. - ** Electrochemical fuel cell type oxygen analyzer **: The oxygen sensor of the Southland oxygen analyzer-OMD640 is based on the principle of an electro-chemical fuel cell. The standard cell (TO2 - 133) is not affected by other background gases such as H2, He, or hydrogen. The acidic cell (TO2 - 233) works in the presence of acidic gases such as carbon dioxide or natural gas. The sensor is independent and requires little maintenance. There is no need to clean the electrodeor add an solute. 2. ** Online Analysis System ** - By installing an online analysis system for the oxygen content in the reaction kettle, the sample gas in the reaction kettle was collected, and the oxygen content value in the sample gas was detected, so as to know the oxygen content value in the reaction kettle. - The system composition of the reactor oxygen content analyzer included three parts: pre-treatment, sample collection, and analysis. In the pre-treatment part, the medium in the sample gas that affects the sensor measurement is removed or diluted to an acceptable concentration by neutralizing, thinning, or absorbing, so as to ensure the life and measurement accuracy of the analysis part. 3. ** Other instruments for testing principles ** - There were also instruments based on the principle of electrochemistry (gas in the primary battery generates an electric current to detect), such as the explosion-proof oxygen analysis system with the product model number of SC-Y500EQ. The working and counter poles were separated by a thin layer of an solute and connected to an external circuit through a small resistance. When the gas diffused into the sensor, the surface of the sensitive pole would undergo an oxidization or reduction reaction to generate an electric current. The current was directly related to the gas concentration and could be measured. - There are also instruments based on the principles of parasitism, optical, laser, etc., such as the HCC-type reactor oxygen content analyzer, which can directly measure the oxygen content in real time and accurately control it through bypass or in-place measurement. It has customized pre-treatment. It has the functions of neutralizing the sample gas with acid and base, removing organic matter, removing water, drying, stabilizing pressure, constant flow, etc., and has safety protection.(When the oxygen concentration value exceeds the first level of the pre-set alarm value, the electromagnetic nitrogen replacement will be automatically turned on until the value drops to the safe range), the nitrogen flow control (equipped with a nitrogen control box, when the oxygen concentration value is within the safe range, the large flow will be automatically cut off to realize the continuous supply of small flow to meet the micro-positive pressure in the kettle machine) and other features, which can realize automatic drainage and reduce personnel maintenance costs. In addition, traditional detection methods also used electrochemistry, ion flow, parasitism, Zirconia, laser, and other principles for detection. When there are special conditions in the reactor (such as the presence of corrosive gases, water vapor, etc.), a gas pre-treatment system may be needed to process the sample gas, remove organic liquids, water, and some impurities before analyzing the oxygen content. If the biochemical oxygen analyzer was used, it could meet the needs of ordinary customers. However, when the gas composition was too complicated to be completely processed by the pre-treatment system, the oxygen content analysis could only be carried out after the pre-treatment system. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction kettle temperature control machine
The reaction kettle custom mold temperature control machine was a temperature control machine carefully developed to meet the production needs of the reaction kettle. From the working principle, it raised the temperature of the heat-conducting oil through the heating device, and used the circulating pump to promote the liquid-phase circulation of the heat-conducting oil. The heat-conducting oil heated up steadily in the form of stacking, and finally met the process requirements. It was different from the traditional reaction kettle electric heater. The traditional method was to insert an electric heat pipe into the reaction kettle jacket to heat up the heat transfer oil. Because the heat transfer oil did not circulate, there would be problems of local overheating and inaccurate temperature control. The custom mold temperature control machine was more accurate. It had many advantages in terms of structure and performance. The heater is easy to install and does not affect the safety of the tank. Its size is only about half of the overall size of the U-shaped tube heat exchange. It can assist the system in venting and dehydration, isolate the contact between the heat-conducting oil and the air, and reduce the loss of heat-conducting oil. There is an oil storage tank, which is used to store the heat-conducting oil in the heating system and drain the heat-conducting oil in the system when necessary. The oil storage tank should be installed at the highest point of the heating system. According to the different heat transfer media, it can be divided into two types: water type and oil type. For occasions where two different temperatures need to be controlled at the same time, the dual-temperature reaction kettle custom-made mold temperature machine is the ideal choice. It is equipped with two independent control systems. In a production environment that requires high temperature control accuracy, a temperature sensor can be installed inside the mold and set on the control panel to ensure that the displayed temperature is consistent with the mold temperature. In the chemical industry, the reaction kettle custom mold temperature machine could improve the product molding efficiency, reduce the generation of defective products, improve the product appearance quality, suppress product defects, speed up production progress, and effectively reduce energy consumption. In terms of temperature control performance, it had the advantages of a large temperature control range, good thermal stability, and fast temperature rise and fall. It could also quickly raise and lower the temperature of the reaction kettle, which was very suitable for the temperature change of the production process. For example, in some medical research situations, because of its small size, convenient installation, and special temperature control method (such as cascaded control that can effectively control the temperature balance of the reactor), it is suitable for situations where the temperature of the reactor is high and needs to be stabilized. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

However, this was only the price of some manufacturers. The price setting of second-hand high-pressure reactors by different manufacturers would also be affected by factors such as the age of the equipment, the year of production, and the performance of the equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Design of the Steam Pipelining Plate of the Reaction Kettle
The design of the reactor steam pipe signboard had to be done properly. First of all, the words 'steam pipe' had to be written clearly on the signboard so that people could know what kind of pipe it was at a glance. Then, the flow of the pipe had to be clearly marked with an arrow to see if it was going into or out of the reactor. The pressure range had to be written down, for example, low pressure, medium pressure, or high pressure steam pipe. The temperature range could not be reduced either. After all, the temperature of the steam was very important. Also, the number of the pipeline had to be included so that it could be quickly located during management and maintenance. The material could also be written down, be it stainless steel or some other material. There were also safety warning signs, such as high temperature danger, so that people would know to be careful when they saw it. With such a signboard, all kinds of information about the steam pipe of the reactor could be seen at a glance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
