Hohhot.com, the heating method of the thermal reaction kettle
The heating forms of the thermal reaction kettle were jacket type and inner coil type. In addition, the common heating method of the reaction kettle was electric heating.(For example, by installing electric heating elements such as resistance wires, silicon carbon rods, and PAC ceramic inside or outside the reactor, the current can be used to generate heat through the resistance to heat the reactor body or heat transfer medium), thermal oil circulation heating, hot water heating, steam heating, etc. However, the document did not indicate whether these heating methods were specifically applicable to the thermal reactor in Hohhot. Generally speaking, the thermal reactor in Hohhot. may also adopt the above heating methods. Read more exciting novels for free

What is the reaction of the aluminum thermal reaction? Is it an exhalation reaction?
Aluminiothermic reaction was a kind of oxide-reduction reaction between aluminum and metal or non-metal compounds at high temperatures. Aluminiothermic reaction was an exhaling reaction, and its heat release was very large, usually enough to heat the product above the melting point, and the reaction could generally occur locally and be self-sustaining. This characteristic also reflected the energy-saving characteristics of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction kettle reconstruction construction plan
The following are some common construction plans for the reactor: ** I. Electromagnetic heating modification plan for the reactor ** 1. ** Power calculation and selection ** - First of all, the known conditions must be clear, such as the material, size (diameter, height, thickness, etc.), weight, effective volume, material weight, material mixing heat, heating temperature requirements, time requirements, etc. - According to the heat calculation formula,[Q = cm/Delta t+km](where [c] is the specific heat capacity,[m] is the mass, and [Delta t] is the temperature difference), the specific heat capacity [J/(KG* ° C)], the temperature difference [° C], and the mass [KG] are substituted into the formula and divided by the time [S] to obtain the power [W]. - For example, the known atmospheric pressure reactor, material 304, the external dimensions of the kettle body are 2 meters in diameter * 3 meters in height (8mm in thickness), the weight is about 1000kg, the effective volume is 7 m3, the material weight is 7 tons, the reaction material is a certain liquid material mixed specific heat according to the requirements of 4200J/kg* ° C, and it is required to be heated from 20 ° C to 280 ° C within 3 hours. After calculating the theoretical power, it is necessary to consider the loss (generally increase the loss by 20%) to determine the actual matching power. For example, the theoretical power of the above example is 708KW, and the actual matching is 708KW *1.2 = 850KW. Seven sets of 120KW electromagnetic heater can be used for parallel heating. 2. ** Steps to design the plan ** - Understand the original structure and working principle of the reactor, including the size, shape, material, working temperature and other parameters of the reactor. Then, according to the actual situation and needs of the reactor, the electromagnetic heating scheme was designed. ** II. Upgrade plan for the support and foam plug at the bottom of the reactor ** 1. ** Selection of Upgrade Materials ** - High-quality steel was used to ensure the bearing capacity and corrosion resistance of the lower support and foam plug. 2. ** Pre-construction preparation ** - The original lower support and foam plug were first cleaned, and then disassembled to facilitate the installation of new materials. 3. ** installation process ** - After determining the size of the new material, he drilled a hole and installed it gently. Then, he adjusted the reaction kettle to ensure that the new support and foam plug were stable. ** 3. Cleaning and replacement of paint containers ** 1. ** Clean paint container ** - Clean up the old paint container, use professional equipment to heat and spray it with high pressure to ensure that it is thoroughly cleaned. 2. ** Change paint container ** - A new paint container was installed, and the corresponding clamp was used to fix the container to ensure safety and reliability. ** IV. Replacing the valve and sensor ** 1. ** Replacing the valve ** - First of all, determine which valve needs to be replaced, then use professional equipment to disassemble it, and choose a suitable position for the new valve to install. 2. ** Replacing the sensor ** - Clean the original sensor, then remove it and mark it according to the location where the new sensor is to be installed. For the modification of the reactor involving the key supervision of dangerous chemical processes (such as the modification of the internal heat-conducting oil-injected electric heating reactor without cooling measures): 1. ** For the atmospheric pressure reaction process using heat medium heating ** - The reaction kettle should be equipped with automatic control valve for feed and heat medium, and the reaction temperature can be adjusted by changing the feed flow or heat medium flow. - The reaction kettle shall be equipped with a high reaction temperature alarm and interlocked to cut off the feed or the heat medium. The parallel lock shall be used to open the emergency cooling system (including the cooling medium) and emergency discharge facilities. 2. ** For the pressure reaction process using heat medium heating ** - The reaction kettle should be equipped with an automatic feed or heat medium flow control valve, which can adjust the reaction temperature and pressure by changing the feed flow or heat medium flow. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Tianshui reaction kettle chemical equipment retail price
According to the reference materials, the retail price of chemical reaction equipment in Tianshui, Gansu Province was as follows: the price of 2000L porcelain reaction pressure tank was 10,000 yuan; the price of stainless steel stirring tank and stainless steel reaction kettle was 6657.00 yuan; the price of high-speed washing liquid vertical stirring machine and high-speed foaming dispersing machine was 4800.0 yuan. The price of a small stainless steel reactor in Guangzhou, Guangdong, was 5,600.00, and the price of a small stainless steel reactor in Wuxi, Jiangsu, was 1,300.00. However, this could be used as a reference to compare the situation in Tianshui. It should be noted that second-hand chemical equipment is generally quoted at 100 - 200 yuan/ton, but this is very different from the retail price of new equipment and is affected by many factors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction mechanism of alcohol and aluminum trioxid under heating
When alcohol was dehydrated into ene, aluminum dioxide was used as a dehydration agent. The alcohol molecules were absorbed on the surface of aluminum dioxide and then dehydrated. The water removed formed aluminum dioxide with aluminum dioxide. This was different from the mechanism of concentrated sulfuric acid protonating the alcohol's hydrogen and then removing water to form carbon ions. However, he did not find out more about the reaction mechanism of the heating reaction of alcohol and aluminum dioxide, so he could not answer accurately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Energy Conversion Method of the carbon reaction
The energy conversion method of the carbon reaction (formerly known as the dark reaction) was to convert active chemical energy into stable chemical energy in C6H12O6 (glucose). During this process, the plastids used the two high-energy compounds, ATP-bound and ADMP-bound, produced by the photoreaction to fix CO2 and convert it into glucose. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
