Description

Technical Field

[0001] This utility model relates to the field of underground safety protection technology in coal mines, specifically to a coal mine active and passive reaction device for carbon monoxide. Background Technology

[0002] In underground blasting operations in coal mines, the detonation of water-based explosives generates a large amount of carbon monoxide gas. Traditional methods rely on ventilation systems for passive dilution, which suffers from problems such as reaction lag and incomplete treatment of dead zones. Existing devices often employ a design where the reactant container is separate from the blasting unit, resulting in complex installation and difficulty in achieving rapid response. Furthermore, insufficient reliability of the fixed structure can easily lead to device displacement, affecting the efficiency of carbon monoxide removal. Summary of the Invention

[0003] The purpose of this invention is to provide a coal mine carbon monoxide active and passive reaction device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coal mine carbon monoxide active and passive reaction device, comprising: mine water-gel explosive (1), carbon monoxide reactant (2), reaction container one (3), built-in tube (4), reaction container two (5), lead tube (6), connecting cover (7), embedded nut (8) and connecting tube (9), the connecting tube (9) passes through the reaction container two (5), one end of the connecting tube (9) is threaded and connected to the embedded nut (8) at one end of the reaction container one (3); the built-in tube (4) is fixed in the reaction container one (3), the carbon monoxide reactant (2) is placed in the built-in tube (4), the mine water-gel explosive (1) is placed between the reaction container one (3) and the built-in tube (4), and the lead wire of the mine water-gel explosive (1) passes out from the lead tube (6) on the connecting cover (7). When the sealing process is completed and the explosive is detonated, the carbon monoxide reactant (2) in the inner tube (4) of the reaction container 1 (3) will react with the carbon monoxide at high temperature. If the carbon monoxide reaction is not sufficient, the residual gas can continue to react with the reactant in the reaction container 2 (5).

[0005] Preferably, the connecting pipe and the connecting cover are connected by a threaded nut.

[0006] Preferably, the connecting cap of the reaction vessel has a lead tube at one end near the connecting pipe.

[0007] Preferably, the reaction vessel one and the reaction vessel two contain carbon monoxide reactant.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] After the mine water-gel explosive is detonated, the carbon monoxide reacts with the carbon monoxide in reaction container one at high temperature and is converted into carbon dioxide. If the carbon monoxide reaction is insufficient, it will react with carbon dioxide in reaction container two. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Please see Figures 1 to 3 This utility model provides a technical solution: a coal mine carbon monoxide active and passive reaction device, comprising: a mine water-based explosive 1, a carbon monoxide reactant 2, a reaction container 3, a reaction container 2, and a connecting pipe 9. One end of the reaction container 3 is connected to a cap 7 with an embedded nut that is threaded onto the connecting pipe. The carbon monoxide reactant 2 is placed in a tube 4 inside the reaction container 3. The mine water-based explosive 1 is placed between the reaction container 3 and the tube 4. The lead wire of the mine water-based explosive 1 is passed through a lead wire tube 6, and the cap 7 is sealed. The connecting pipe 9 is passed through the reaction container 2 and connected to the threaded nut 7. After the sealing process is completed, the explosive is detonated. After the reaction container 3 ruptures, the carbon monoxide reactant 2 inside reacts actively with the carbon monoxide. If the carbon monoxide reaction is incomplete, the residual gas can react with the reactant in the reaction container 2.

[0014] When this device is in operation, during mining operations, after deep-hole blasting, toxic and harmful gases will enter the working face through cracks, which will pose a great threat to the life safety of people working in the mine. The harmful gas is mainly carbon monoxide. By placing the assembled device in the rock borehole, after the mine water-gel explosive 1 is detonated, the carbon monoxide reactant 2 in reaction container 1 3 reacts with carbon monoxide at high temperature and is converted into carbon dioxide. If the toxic and harmful gases do not react fully, they will react with them in reaction container 2 5.

[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
