Description

Technical Field

[0001] This utility model mainly relates to the field of chemical reactions, specifically to an emergency protection device for chemical reaction explosions. Background Technology

[0002] In chemical reaction processes, reactants, solvents, and other liquid materials are first pumped into the reactor through pipelines installed within the workshop. Therefore, the safety performance of the pipelines used for pumping materials is crucial for improving production safety.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Chemical reaction pipelines are generally manufactured using a single-piece molding process. However, the pipelines are connected by flanges, which can easily lead to leaks. When leaked materials or solvents come into contact with air or a source of ignition, they can easily cause sparks or release harmful gases.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] This utility model provides an emergency protection device for chemical reaction explosions, which solves the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows: a chemical reaction explosion emergency protection device, including a chemical conveying pipeline structure, flange connection sealing structures are provided on both sides of the outer wall of the chemical conveying pipeline structure, the number of chemical conveying pipeline structures is set to multiple, an adsorption structure is provided between two chemical conveying pipeline structures, and the adsorption structure is slidably connected to the flange connection sealing structure.

[0010] An adsorption structure includes a lifting housing, with installation chambers on both sides inside the lifting housing, and vent holes on the outer wall of the lifting housing connected to the installation chambers. The installation chambers are filled with packing material.

[0011] The flange connection sealing structure is installed at the connection point between two chemical conveying pipeline structures. In the event of a leak, the packing inside the installation chamber corresponds to the materials and solvents conveyed inside the chemical conveying pipeline structure. The packing absorbs and decomposes the materials and solvents, preventing or slowing down the explosion caused by the materials and solvents coming into contact with air or ignition sources. This effectively allows personnel to evacuate and thus plays a role in emergency protection.

[0012] Furthermore, the number of pipe bodies is set to two, and a connecting flange is provided at one end of each pipe body. The connecting flanges of the two pipe bodies fit together and are connected by a first bolt. A second bolt is provided inside the through hole inside the connecting flange.

[0013] Furthermore, the flange connection sealing structure includes a housing, and the number of housings is set to two. A connecting groove is provided inside the housing, and the inner wall of the connecting groove is fitted with the outer wall of the pipe body.

[0014] Furthermore, an adhesive block is provided on the inner side of the enclosure shell, the outer wall of the adhesive block is fitted with the outer wall of the connecting flange, a bolt hole is provided inside the adhesive block, the inner wall of the bolt hole is fitted with the outer wall of the second bolt, and an installation groove is provided on the top of the enclosure shell.

[0015] Furthermore, the enclosure shell is slidably connected to the inside of the mounting groove, and a spring telescopic rod is provided between the enclosure shell and the mounting groove.

[0016] Furthermore, fitting grooves are provided on both sides of the lifting housing, and pressure sensors are provided on both sides of the inner wall of the fitting grooves.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] This invention utilizes an adsorption structure to allow the packing material inside the installation chamber to adsorb and neutralize materials and solvents leaking from the chemical transport pipeline structure. This prevents the materials and solvents from directly contacting air or ignition sources and causing an explosion. Furthermore, when the leak is significant, the packing material can also adsorb the materials and solvents, slowing down the time before an explosion and allowing more time for personnel to evacuate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0030] See attached document Figure 1-4 An emergency protection device for chemical reaction explosion includes a chemical conveying pipeline structure 1, with flange connection sealing structures 2 provided on both sides of the outer wall of the chemical conveying pipeline structure 1. The number of chemical conveying pipeline structures 1 is set to multiple, and an adsorption structure 3 is provided between two chemical conveying pipeline structures 1. The adsorption structure 3 is slidably connected to the flange connection sealing structure 2.

[0031] The adsorption structure 3 includes a lifting housing 301, with installation chambers 303 on both sides inside the lifting housing 301, and ventilation holes 304 on the outer wall of the lifting housing 301. The ventilation holes 304 are connected to the installation chambers 303, and the interior of the installation chambers 303 is filled with packing material.

[0032] The flange connection sealing structure 2 is installed at the connection position between the two chemical conveying pipeline structures 1. When a leak occurs, the packing inside the installation chamber 303 corresponds to the materials and solvents conveyed inside the chemical conveying pipeline structure 1. The packing absorbs and decomposes the materials and solvents to prevent them from coming into contact with air or ignition sources and causing an explosion, or to slow down the explosion time. This effectively allows personnel to evacuate and thus plays a role in emergency protection.

[0033] Furthermore, the number of pipe bodies 101 is set to two. One end of each pipe body 101 is provided with a connecting flange 102. The two connecting flanges 102 of the two pipe bodies 101 are fitted together and connected by a first bolt 103. A second bolt 104 is provided inside the through hole of each connecting flange 102. The flange connection sealing structure 2 includes a housing 201. The number of housings 201 is set to two. A connecting groove 202 is formed inside each housing 201. The inner wall of the connecting groove 202 is fitted to the outer wall of the pipe body 101. A fitting block 203 is provided on the inner side of each housing 201. The outer wall of the fitting block 203 is fitted to the outer wall of the connecting flange 102. The inner wall of the casing 201 is provided with bolt holes 204, and the inner wall of the bolt holes 204 fits against the outer wall of the second bolt 104. The top of the casing 201 is provided with a mounting groove 205, and the casing 201 is slidably connected to the inside of the mounting groove 205. A spring telescopic rod is provided between the casing 201 and the mounting groove 205. The two pipe bodies 101 are connected by a connecting flange 102. The outer wall of the connecting flange 102 is installed with a first bolt 103 to fix the two pipe bodies 101. Then, the casing 201 is installed on both sides of the connecting flange 102. The second bolt 104 is inserted into the bolt holes 204 inside the two casings 201. The second bolt 104 also passes through the connecting flange 102, so that the two casings 201 wrap around the connecting flange 102.

[0034] Furthermore, the lifting housing 301 has fitting grooves 302 on both sides, and pressure sensors 305 are installed on both sides of the inner wall of the fitting grooves 302. When materials, solvents, etc., are transported by the chemical conveying pipeline structure 1, corresponding fillers are placed inside the installation chamber 303, and when leakage occurs between the connecting flanges 102, the pressure inside the housing 201 increases. The pressure sensor 305 inside the lifting housing 301 detects the increase in pressure and activates the electric telescopic rod. The electric telescopic rod drives the lifting housing 301 into the flange connection sealing structure 2 to seal between the two chemical conveying pipeline structures 1. Then, the fillers inside the installation chamber 303 adsorb and neutralize the leaked materials, solvents, etc., thereby preventing explosions caused by the leaked materials, solvents, etc., coming into contact with air or ignition sources during the chemical reaction and transportation process, and realizing the function of emergency protection against leaked materials, solvents, etc.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
