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.

Reaction Kettle, Enamel Kettle, Stainless Steel Kettle, Storage Tank
The reaction kettle was a type of pressure vessel used to complete the processes of sulfidification, nitration, dehydration, dehydration, condensation, and so on. Commonly seen were porcelain reaction kettles and stainless steel reaction kettles. The porcelain reactor was made of carbon steel. A layer of porcelain was burned on the surface of the contact material. The anti-corrosion ability of the porcelain layer was used to isolate the contact between the material and the carbon steel to protect the reactor body from corrosion. The temperature of the material could not exceed 200 degrees Celsius. If the temperature was too high, it would cause the glaze layer to melt. It was an open structure. The upper head and the kettle body were connected by a flange-like connection and filled with an anti-corrosion sealing mat. The pressure that could be maintained in the kettle did not exceed 4 kg. It is suitable for corrosive materials. The stainless steel reactor was made of stainless steel. According to the requirements of the material, it could be equipped with heating, cooling, high pressure, vacuum and other functions. The material temperature could reach 400 degrees Celsius, and the kettle could maintain a pressure of tens of kilograms or even hundreds of kilograms, but its corrosion resistance was worse than that of the porcelain reactor. However, the information provided by the storage tank did not include detailed information about the comparison of the reactor functions with the porcelain kettle and the stainless steel kettle. It was impossible to give detailed information under the same logic as the former two. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Supercritical Oxidation Reaction Kettle
The Supercritical Oxidation Reaction Kettle was the key equipment in the Supercritical Oxidation Technology. The principle was to use the ability of the water to dissolve non-polar organic compounds in the supercritical state of water (temperature> 373.99 ° C, pressure> 22.064MP), so that the organic compounds could be completely dissolved with oxygen and air in the supercritical water and be uniformly oxided, thereby destroying the structure of the organic matter and achieving the purpose of efficiently processing the organic matter. In terms of structure, for example, there was a type of super-critical water oxidization reactor that included an injection device, a reactor, an isolation sleeve with cooling and isolation functions, an external heating device, a safety valve, a temperature sensor, and a pressure sensor. The feeding port of the reaction kettle adopted the feeding method of spraying and mixing, the spraying device was located at the top of the reaction kettle inside the isolation sleeve with cooling effect, the discharge port was located at the top of the reaction kettle outside the isolation sleeve with cooling effect, the salt discharge port was located at the bottom of the reaction kettle, and the external heating device was located on the shell of the reaction kettle. This structural design could effectively shorten the time needed for the waste liquid reaction preparation, prevent the waste liquid from forming supercooled liquid due to the difference in heat absorption and accumulating in the reaction kettle, effectively extend the flow path of the reagents, and reduce the flow interference caused by the discharge pressure fluctuation. In addition, the separation of the heating and cooling structures was beneficial to the temperature control of the reaction kettle. In the process of the super-critical oxygen reaction, the waste water is first subjected to the pre-treatment such as the adjustment of the pH-value or the removal of the chloride-ions in the pre-treatment tank.(Before entering the super-critical water, the waste water has a pH-value of not less than 7 and a chloride-ion content of less than 10000 milligrams per liter.) After that, the waste water enters the super-critical water oxidization reaction kettle, and is mixed with gaseous oxidisers such as oxygen, oxygen rich air, or air. The mixture will undergo an oxidization reaction in the reaction kettle, and the organic substances will be decomposed into small molecular products. After the reaction products are cooled and depressured, they will be separated into gas-liquid and solid-liquid by a separation device. The heat required for the SCWOx reaction is provided by the organic matter in the waste water or the fuel or the electric heating device. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction kettle feeding work
The feeding work of the reactor has the following points: * * 1. Solid Material Charging ** 1. * * Material Pretreatment ** - For block-like solid materials, they needed to be processed into small pieces before being thrown into the reaction kettle. This would help the materials mix better with the liquid in the reaction kettle and improve the reaction efficiency. 2. * * Stirrer related operations ** - Before starting the stirring, first use your hand to rotate the stirring device to ensure that it does not get stuck or collide with easily damaged parts such as the thermometer tube. Then, press the electric switch to activate it. When the agitators can operate normally, then officially start the agitation operation. It is strictly forbidden to start it by force, so as to prevent solid materials from being stuck or colliding with the thermometer tube, causing equipment damage or test failure. 3. * * To prevent damage to the pot wall and falling into hard objects ** - When adding solid materials, be careful to avoid damaging the pot wall. If there is a dangerous medium in the reaction kettle, it is strictly forbidden for metal or hard objects to fall into the pot. * * 2. Liquid Material Charging ** 1. * * Vacuum pumping condition ** - If the liquid material is put in by vacuum pumping, the vacuum valve should be delayed to prevent flushing. Before opening the vacuum valve, he had to first ensure that the pressure in the reaction kettle was stable, and then gradually open the valve to allow the liquid material to slowly enter the reaction kettle. * * 3. Inspection before feeding ** 1. * * Material Inspection ** - Before feeding the materials into the reactor, the materials must be subjected to "self-inspection, re-inspection, and special inspection". Only when the "three inspections" are consistent can the materials be fed into the reactor. * * IV. Other precautions during feeding ** 1. * * According to the process operation procedure ** - In the process of adding materials, the time, speed, type, number, temperature rise, temperature drop, and heat preservation must be carried out in accordance with the process operation procedures to ensure the accuracy and reliability of the experimental results. 2. * * Surveillance during closed reaction ** - During the closed reaction, one needed to constantly observe the pressure, temperature, and other parameters inside and outside the kettle. If abnormal situations are discovered, measures should be taken in time to prevent safety accidents. For example, if the pressure was too high or the temperature was too high, it might cause the reactor to rupture or cause other safety accidents. 3. * * Equipment Operation Check ** - After the power is connected, the motor should drive the stirring operation, and check whether there is any state change phenomenon, sound, etc. in the transmission parts such as the decelerator and stirring to ensure the normal operation of the equipment, and find and deal with potential problems in time. If any abnormal phenomenon or sound is found, it should be immediately shut down for inspection to prevent equipment damage or affect the experiment results. 4. * * Personnel and product safety ** - Pay attention to personal safety and product safety at all times when feeding materials into the kettle. 5. * * Record and clean up ** - After feeding the materials, they had to re-check and sign the "Material List" for confirmation, and then clean up the garbage on the spot in time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The lid of the reaction kettle loosened after the thermal reaction
The loosening of the cover of the reaction kettle after the thermal reaction may be due to the following reasons: 1. It was caused by not tightening it. If it could be dragged, it meant that the upper steel sheet of the inner liner was not placed properly (after the upper steel sheet was placed properly, the vibration force generated by the screw thread gap between the lid and the kettle body caused the upper steel sheet to run out). If it could not be dragged, it meant that the upper steel sheet had been placed properly. 2. The inner liner contracted faster than the steel. After the thermal reaction kettle cooled down, the inner liner contracted faster, while the steel contracted slower. Therefore, the kettle cover would be loose and could still be twisted. 3. If the pressure in the reaction kettle was not high enough, the reaction conditions would be destroyed, and the lid might also be loosened. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
