Sui Xing machine electric heating reactor application:

     The reactor is widely used in petroleum, chemical, rubber, pesticide, dyestuff, medicine, food, pressure vessel for the process of vulcanization, nitrification, hydrogenation, alkylation, polymerization and condensation. For example, reactor, reaction pot, decomposition pot , Polymerization reactor, etc .; materials generally have carbon steel, stainless steel and other materials.

Reactor use and characteristics:

  The general understanding of the reactor is a physical or chemical reaction of stainless steel containers, through the container structure design and parameter configuration, to achieve the process requirements of heating, evaporation, cooling and low-speed mixing function. The pressure in the reaction process requires that the design requirements for the containers are not the same. Production must be in strict accordance with the corresponding standard processing, testing and test run. Stainless steel reactor can be based on different production processes, operating conditions are not the same, the reactor design structure and parameters are different, that is, the structure of the reactor different styles, are non-standard container equipment.

  Stainless steel reactor is widely used in petroleum, chemical, rubber, pesticide, dyes, pharmaceuticals, food and other production users and a variety of scientific research project research, used to complete the hydrolysis, and, crystallization, distillation, evaporation, storage, Alkylation, polymerization, condensation, heating mixing, constant temperature reaction process of the container.

  The reactor is a comprehensive reaction vessel, according to the reaction conditions on the reactor structure and function of the design of accessories. From the beginning of the feed - reaction - the discharge can be a higher degree of automation to complete the pre-set reaction steps, the reaction process temperature, pressure, mechanical control (stirring, blowing, etc.), reactants / products Concentration and other important parameters for strict control.

  The reactor material is generally carbon steel, stainless steel and other materials. The reactor can be made of stainless steel 304,316 stainless steel. The stirrer has anchor type, frame type, paddle type, turbine type, scraper type, modular type, rotary mechanism can be used cycloid reducer, CVT or frequency control, etc., to meet the special Reaction requirements. Sealing device can be used mechanical seal, packing seal and other sealing structure. Heating, cooling can be used jacket, half tube, coil, Miller board and other structures, heating methods are steam, electric heating, heat transfer oil to meet the acid, high temperature, wear resistance, corrosion and other different working environment need. According to the user process requirements for the design, manufacture.

structure type

  The reactor consists of kettle body, kettle cover, jacket, stirrer, transmission, shaft seal, support and other components. Stirring type generally have anchor type, paddle type, turbine type, propulsion type or frame type. The stirring device can use the multi-layer stirring blade when the height is relatively large, and can also be arbitrarily selected according to the requirements of the user. And set the jacket outside the kettle wall, or in the device to set the heat transfer surface, but also through the external circulation for heat transfer. Heating methods are electric heating, hot water heating, hot oil circulation heating, far infrared heating, outside (inside) coil heating, cooling method for the jacket cooling and kettle coil cooling, stirring the form of the blade and so on. Bearing seat with a support or ear-type bearings and so on. Speed more than 160 rpm should use gear reducer. The number of openings,

Specifications or other requirements can be designed according to user requirements, production.

Installation Use:

  1, should be installed in a solid, flat table, the height of the table according to the use of the decision, equipment and workstations around the room should be left some space (≥ 360cm) for installation and post-maintenance.

  2, the installation requirements of the drive shaft and horizontal to the horizontal plane, not vertical (tilt) shall not be greater than the total height of the equipment 1/1000.

  3, the equipment itself to take over the process of self-spare parts, safety valve, must be equipped with the requirements of the reactor.

  4, the installation is completed check the connection parts and transmission parts are solid and reliable, the connection pipes, nozzles, seals and the whole air tightness test should be no bubble, take, drip, leakage phenomenon.

  5, before the boot reducer into the 46 # mechanical oil, open the motor shield with hand rotation fan check whether the phenomenon of card idle, stirring paddle with no scraping wall phenomenon, clean up the dirt inside the kettle, before starting. Empty car running for 30 minutes without normal noise, vibration, before the official feeding production. Another depending on the production of regular replacement of reducer oil.

Electric heating reactor of various technical parameters

maintain

(1) installation: the reactor should be installed in the explosion-proof requirements of the high-pressure operating room, equipped with multiple reactors should be placed separately, each between the application of a safe explosion-proof wall separated, each operating room should be There are channels and outlets leading to the outside, when the presence of explosive media should ensure that the equipment is well ventilated.

(2) After unpacking the equipment, check the equipment for damage. According to the equipment model, install the equipment according to the structure. The spare parts are checked according to the packing list. If the heating oil is heated, please use the temperature to buy the corresponding type of heat transfer oil (Note: the heat transfer oil is absolutely not allowed to contain water) to join, when the upper part of the jacket to open the mouth and the jacket in the upper part of the oil Bit open. Through the fuel tank to the inside of the fuel, to be oil when the mouth can be oil; after the mouth bit dead, do not wrinkle the tank to avoid pressure.

(3) kettle body, kettle cover installation and sealing: kettle body and kettle cover with gasket or cone surface with the circular surface of the line, by tightening the main nut so that they are pressed against each other, to achieve a good sealing effect. Tighten the nut, you must diagonally symmetrical, step by step afterburner tightening, force evenly, does not allow the kettle cover to the side of the tilt, in order to achieve a good sealing effect. When tightening the main nut, do not exceed the specified tightening torque 40 ~ 120N.M range, to prevent the sealing surface crushing or overload wear. The cover should be particularly care, each time before the installation with a relatively soft paper or cloth to clean up and down the sealing surface, with particular attention to the kettle body, kettle cover surface scratches the scar. If reasonable operation, you can use more than 10,000 times. Seal surface damage, the need to re-repair can be achieved before the good sealing performance. Remove the kettle cover should be slowly lifted up and down the kettle cover, to prevent the kettle body and the lid between the sealing surface collide with each other. If the seal is a gasket (PTFE, aluminum pad, copper pad, asbestos pad, etc.) seal, by tightening the main nut will be able to achieve a good sealing effect.

(4) the installation of valves, pressure gauges, safety valves by tightening the positive and negative nut, that is, to achieve the effect of sealing, connecting the two arc sealing surface shall not be relative to the rotation of all screw joints in the assembly, must be coated with lubricant or Oil to reconcile the graphite, so as not to bite. The use of the valve: needle valve line seal, just gently turn the valve needle, pressing the sealing surface that can achieve good sealing performance, prohibit excessive force, so as not to damage the sealing surface.

(5) After the equipment is installed, pass a certain amount of nitrogen for 30 minutes to check for leaks. If there is a leak, please use the soap filter to find the pipe, the nozzle leak, find out the gas tightening, Pass nitrogen pressure test to ensure that no leakage began to work properly.

(6) when the cooling cooling, the water can be cooled by the cooling coil, to prohibit the speed of cold, to prevent excessive temperature stress, resulting in cooling coil, kettle body cracks. Work when the kettle temperature exceeds 100 ℃, the magnetic stirrer and kettle cover water jacket should be through the cooling water to ensure that the water temperature is less than 35 ℃, so as not to magnet demagnetization.
