Description

Technical Field

[0001] The utility model belongs to the technical field of chemical safety, and in particular relates to a safe explosion-proof structure for a chemical reactor. Background Art

[0002] Reactor is a comprehensive reaction vessel. The design of the reactor structure and accessories is based on the reaction conditions to achieve the heating, evaporation, cooling and mixing functions required by the process. Reactor is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food, and is used to complete the pressure vessels of vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation and other process. In chemical production, reactor is widely used. When the reactor is working, in order to balance the internal pressure, it is necessary to exhaust the inside. The traditional exhaust operation cannot automatically adjust the stability of the internal air pressure, and the safety is poor. If the internal pressure of the reactor is too high, it is easy to cause the internal air pressure of the reactor to be too high, affecting the normal use of the reactor, and it is easy to explode, causing danger. These defects are addressed in Chinese patent CN 217189509 U proposes a high-temperature reactor with an explosion-proof structure, including a reactor outer shell and a reactor inner shell. The outer wall of the reactor inner shell is in contact with the inner wall of the reactor outer shell, and the internal expansion force is further transmitted to the reset spring, and then the expansion force is transmitted to the contactor through the reset spring. The expansion force value is transmitted to the pressure display gauge through the contactor through a data line for display, which is convenient for the operator to observe. At the same time, the reset spring can also effectively buffer and filter the expansion force to ensure the safety of the reactor inner shell.

[0003] However, the inventors believe that the above technology cannot properly handle the deflated gas, and directly discharging the gas may cause pollution due to the chemical substances contained therein. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] Please also refer to Figures 1 to 4 The safety explosion-proof structure of the chemical reactor in the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the safety explosion-proof structure of the chemical reactor includes a collecting frame 1 screwed onto the outside of the reactor body and a gas relief pipe 2 connected to the collecting frame 1. The collecting frame 1 is annular and has a cavity inside. One end of the gas relief pipe 2 extends into the collecting frame 1 and the other end is connected to the inside of the reactor body. Two gas relief pipes 2 are symmetrically arranged about the reactor body. A partition plate 3 is fixed inside the collecting frame 1. The partition plate 3 divides the internal space of the collecting frame 1 into a gas outlet area 4 and a filtering and adsorption area 5.

[0025] In this embodiment, the collecting frame 1 is installed by screws to the side of the reaction kettle body. Specifically, a threaded connection hole (not shown in the figure) is provided on the side of the reaction kettle body.

[0026] As an implementation mode, an air guide pipe 6 is slidably connected inside the air deflation pipe 2, a baffle 7 is fixed to the end of the air guide pipe 6 away from the air deflation pipe 2, a connecting rod 8 is fixed to the end of the baffle 7 facing the air deflation pipe 2, the connecting rod 8 slides on the side of the air deflation pipe 2 away from the baffle 7, and two connecting rods 8 are symmetrically arranged.

[0027] Among them, a fixed block 9 is fixed to the outside of the air leakage pipe 2, and the connecting rod 8 slides inside the fixed block 9. A fixed plate 10 is fixed to the end of the connecting rod 8 away from the cover plate. A spring 11 is fixed between the fixed plate 10 and the fixed block 9. The spring 11 is sleeved on the outside of the connecting rod 8, and a plurality of air leakage holes 17 are provided on the outer side of the air guide pipe 6.

[0028] During actual use, when the pressure inside the reactor body is too high, the gas gathers at the top of the reactor body, and when the pressure is too high, the internal gas automatically resists the air duct 6 inside the air leakage pipe 2, causing the air duct 6 to move along the air leakage pipe 2. The air duct 6 drives the connecting rod 8 to move inside the fixed block 9. At the same time, the spring 11 between the fixed plate 10 and the fixed block 9 is in a compressed state. After the air duct 6 moves, the air leakage hole 17 thereon is exposed, and the gas inside the reactor body is discharged along the air leakage hole 17 to the inside of the collection frame 1.

[0029] A filtering and adsorption area 5 and an exhaust area 4 are arranged inside the collecting frame 1. A rotating shaft 12 is rotatably connected inside the filtering and adsorption area 5. One end of the rotating shaft 12 extends out of the collecting frame 1, and a motor 13 is connected to the extended end. The rotating shaft 12 is arranged near the exhaust pipe 2. A stirring blade 14 is fixed to the outside of the rotating shaft 12. A number of stirring blades 14 are arranged along the circumferential direction of the rotating shaft 12. A number of activated carbon particles are prevented from being present inside the adsorption and filtration area. In this embodiment, an opening for placing activated carbon particles may be provided at the top of the collecting frame 1.

[0030] A plurality of air outlet holes 15 are provided at the top of the air outlet area 4 .

[0031] Meanwhile, the adsorption and filtration area is larger than the gas outlet area 4 , and a plurality of through holes 16 are provided on the partition plate 3 , and the through holes 16 are used to connect the adsorption and filtration area with the gas outlet area 4 .

[0032] The gas inside the reactor body enters the collecting frame 1 through the vent hole 17. The above-mentioned motor 13 can drive the rotating shaft 12 to rotate, driving the stirring blades 14 to stir the activated carbon particles placed inside, so that the activated carbon particles are fully in contact with the gas and adsorb large particles and other pollutants therein. At the same time, after the adsorption, the gas enters the gas outlet area 4 along the through hole 16 on the partition plate 3, and is further discharged along the gas outlet hole 15 in the gas outlet area 4.

[0033] When the gas inside the reactor body is discharged and the internal pressure returns to normal, the spring 11 automatically returns to its initial state, thereby driving the air guide pipe 6 to slide toward the inside of the air leakage pipe 2 to seal the air leakage pipe 2 again.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
