Description

Technical Field

[0001] The utility model belongs to the technical field of gas equipment, in particular to a mine gas diluter. Background Art

[0002] The induced gas diluter is a special equipment for treating excessive gas accumulation in coal mines. The induced gas diluter uses compressed air from the underground compressed air system as its power. It has no impeller, no moving parts, does not use power, and does not produce sparks. It is safe and reliable to use in environments with explosive gases. In practice, it can effectively reduce the gas concentration in the upper corners of coal mines.

[0003] However, the existing high-pressure gas nozzles of mining gas diluters are mostly set inside the gas diluters. Due to the fast airflow speed, the local flow velocity is large, which cannot drive the air of the entire gas diluter to flow and mix quickly, thereby diluting the incoming gas. At the same time, the air inlet is relatively concentrated, and the surrounding gas cannot be effectively sucked in for dilution. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model proposes a mining gas diluter, which effectively solves the problem that the high-pressure gas nozzles of the mining gas diluter are mostly arranged inside the gas diluter. Due to the fast air flow speed, the local flow velocity is large, which cannot drive the air of the entire gas diluter to flow and mix quickly, thereby diluting the incoming gas. At the same time, the air inlet is relatively concentrated, and the surrounding gas cannot be effectively sucked in for dilution.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a mining gas diluter, which includes a fixed seat, an air duct, a gas injection structure and a dispersed air intake structure. The air duct is fixed on the fixed seat, the gas injection structure is arranged on the air duct, and the dispersed air intake structure is arranged on the air duct. The gas injection structure includes an injection pipe, a manifold and a connecting head. The injection pipe is fixedly arranged through the air duct, the manifold is connected to the injection pipe, and the connecting head is connected through the manifold.

[0006] Preferably, the dispersed air intake structure includes an air intake pipe 1 and an air intake pipe 2, wherein the air intake pipe 1 is fixedly arranged through the rear end of the air duct, and the air intake pipe 2 is obliquely arranged on the side wall of the rear end of the air duct.

[0007] In order to better achieve the effect of spiral forward mixing of the air flow, the air outlet on the air jet pipe is tilted to point to the inner wall of the air duct and the air jet pipe is arranged in three groups at a 120-degree angle to form a circle.

[0008] In order to achieve the purpose of forming vortex negative pressure more quickly, the air jet pipe simultaneously ejects airflow that spirals forward in the air duct to mix with the gas.

[0009] Furthermore, the air intake pipes are arranged in four groups and are distributed around the rear end.

[0010] In order to achieve the fire prevention effect, the air duct is made of insulating material.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows: the mine gas diluter proposed in this scheme blows out spirally forward gas through the jet pipe to form a negative pressure, and inhales high-concentration gas through the intake pipe 1 and the intake pipe 2, performs vortex mixing and dilution, and improves the dilution effect.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model proposes a mining gas diluter, including a fixed base 1, an air duct 2, a gas injection structure 3 and a dispersed air intake structure 4. The air duct 2 is fixed on the fixed base 1, and the air duct 2 is made of insulating material. The gas injection structure 3 is arranged on the air duct 2, and the dispersed air intake structure 4 is arranged on the air duct 2. The gas injection structure 3 includes an injection pipe 5, a manifold 6 and a connector 7. The injection pipe 5 is fixedly arranged through the air duct 2. The air outlet on the injection pipe 5 is inclined to point to the inner wall of the air duct 2, and the injection pipe 5 is arranged in three groups at a hundred and twenty degrees in a circular shape. The injection pipe 5 simultaneously ejects airflow that spirals forward in the air duct 2 to mix the gas. The manifold 6 is connected to the injection pipe 5, and the connector 7 is connected through the manifold 6.

[0020] like Figure 1 、 Figure 3 and Figure 4 As shown, the dispersed air intake structure 4 includes an air intake pipe 1 8 and an air intake pipe 2 9. The air intake pipe 1 8 is fixedly arranged through the rear end of the air duct 2. Four groups of air intake pipes 8 are arranged and dispersed around the rear end. The air intake pipe 2 9 is tilted and arranged on the side wall of the rear end of the air duct 2.

[0021] During specific use, when the user uses this device, he uses the fixing seat 1 to fix the air duct 2 in the mine, and then connects it to the outlet pipe of the high-pressure air pump through the connector 7, and then controls the high-pressure air pump to work and spray, so that the high-pressure gas is evenly sprayed out through the jet pipe 5 through the manifold 6. At this time, the gas sprayed by the jet pipe 5 forms a spiral vortex in the air duct 2 and flows forward, thereby forming a negative pressure at the rear. At this time, the high-concentration gas at the rear is sucked into the air duct 2 through the air inlet pipe 8 to mix and dilute the surrounding gas, thereby achieving the purpose of efficient and safe dilution. The above is the entire use process of the mine gas diluter.
