Description
Technical Field
The invention relates to the technical field of reaction kettle equipment, in particular to pressure cooking reaction kettle equipment.
Background
The traditional high-temperature high-pressure reaction kettle is a reactor operated at high temperature and high pressure, is widely applied to petroleum, chemical industry, rubber, pesticides, dyes, medicines and foods, and is used for completing the technological processes of vulcanization, nitration, hydrogenation, hydrocarbylation, polymerization, condensation and the like, such as a reactor, a reaction kettle, a decomposition kettle, a polymerization kettle and the like; the materials are typically carbon manganese steel, stainless steel, zirconium, nickel-based (hastelloy, monel, and Kang Nie) alloys and other composite materials.
As shown in FIG. 2, the traditional high-temperature high-pressure reaction kettle consists of a stirrer, a reaction container, a transmission system, a safety device, a cooling device, a heating furnace and the like. The method is characterized by comprising the following steps: (1) The kettle body and the kettle cover are processed by using specific stainless steel, wherein the kettle body is connected with threads through a flange, the kettle cover is a regular flat plate cover, and the two parts are fixedly connected by nuts and main bolts which are circumferentially distributed; (2) The main sealing port of the high-pressure reaction kettle is sealed by double lines, and the rest sealing points are generally in a sealing mode of line contact of a plane with an arc surface and a circular arc surface, and a very good sealing effect is achieved by virtue of ultrahigh precision and smoothness of the contact surface; (3) The kettle body is provided with a barrel-shaped silicon carbide furnace core, an electric furnace wire penetrates through the furnace core, the end head of the electric furnace wire penetrates out from the lower part of the side of the furnace shell, and the electric furnace wire is connected with a controller through a wiring stud and a rubber sleeve cable; (4) The coupling is mainly composed of a pair of inner and outer magnetic rings with strong magnetic force, and a pressure-bearing spacer is arranged in the middle of the coupling. The stirrer is driven by a servo motor through a coupling. The stirring rotating speed can be controlled by controlling the rotating speed of the servo motor; (5) The upper part of the spacer bush is provided with a speed measuring coil, when the stirrer and the inner magnetic ring which are connected into a whole rotate, the speed measuring coil generates induced electromotive force, the electromotive force corresponds to the stirring rotating speed, and the electromotive force is transmitted to the tachometer to display the stirring rotating speed; (6) The pressure gauge, the rupture disk safety device, the gas-liquid phase valve, the temperature sensor and the like are arranged on the kettle cover, so that the reaction condition in the kettle can be known at any time, the medium proportion in the kettle can be regulated, and the safe operation of the high-pressure reaction kettle can be ensured; (7) The bearing adopts a stainless steel bearing or high-strength electrographite, is wear-resistant and has long maintenance period; (8) A cooling water jacket is arranged between the magnetic coupling and the kettle cover, and cooling water is introduced when the operation temperature is higher, and the temperature of the magnetic steel is too high to demagnetize.
However, the above conventional high temperature and high pressure reactor has the following drawbacks: (1) The high-pressure reaction kettle is required to periodically check the swinging quantity of the lower stirring shaft, and if the swinging quantity is found to be large, the bearing and the shaft sleeve are required to be replaced by disassembling immediately according to the structure diagram; (2) The kettle cover and the kettle body are of split design, and leakage is easy to occur at the sealing surface. The cover and the body of the miniature high-pressure reaction kettle are loosened or damaged by the screw threads of the nuts or the sealing surfaces in the repeated disassembly and assembly process. The method of elimination is that the nut is re-screwed, and the polishing sealing surface is trimmed; (3) The motor rotates, the magnet does not rotate, the current of the motor is reduced, the temperature in the miniature high-pressure reaction kettle is too high, a cooling system has a problem, and the magnet is demagnetized due to high temperature; (4) Friction noise is generated during stirring, and when the reaction solution is crystallized or solid, the inner magnetic drive of the magnetic coupler is easy to be blocked and worn; (5) The reaction for generating a large amount of gas cannot be applied, the explosion is easy, and no corresponding exhaust design exists; (6) The price of the magnetic stirrer is higher, while the high-pressure magnetic stirring reaction kettle is required to have higher temperature and pressure performance, so the price is higher; (7) Because the reaction kettle and the stirrer need to be sealed, the leakage risk of the high-pressure magnetic stirring reaction kettle is relatively high; (8) Because the reaction is carried out under the high-pressure and high-temperature state, some reactants and products adhere to the wall of the reaction kettle and the stirrer, and the cleaning is difficult.
