[0001] The present invention relates to the technical field of coal mine ventilation, and specifically relates to a comprehensive treatment system for hydrogen sulfide gas in coal mines Background Art

[0002] Hydrogen sulfide is a gas with irritation and asphyxiation properties. During the drilling process in coal mine underground geological exploration, hydrogen sulfide gas can escape from coal and rock strata. In mining, processes such as blasting, coal mining, transportation, loading, and support may generate hydrogen sulfide gas. When the concentration of hydrogen sulfide gas in the underground air is too high, timely ventilation is required

DETAILED DESCRIPTION OF THE INVENTION

[0053] For better explaining the present invention for easy understanding, the technical solutions and effects of the present invention will be described in detail below in conjunction with the accompanying Figures 1-5 , through specific embodiments.

[0054] Please refer to Figure 1 , this embodiment provides a comprehensive treatment system for hydrogen sulfide gas in coal mines, including:

[0055] A driving vehicle body 1, on one side of which an intake assembly 2 is fixed;

[0056] A first spraying assembly 3, fixed on the driving vehicle body 1 and communicating with the intake assembly 2;

[0057] A second spraying assembly 5, fixed on the driving vehicle body 1 and connected to the first spraying assembly 3 through a connecting pipe 4;

[0058] A spraying pump 6, fixed on the driving vehicle body 1 and communicating with the first spraying assembly 3 and the second spraying assembly 5;

[0059] An outlet 7, opened on one side of the driving vehicle body 1.

[0060] It should be noted that by switching the state of the intake assembly 2 during different operations in the coal mine, energy consumption can be saved on the premise of treating hydrogen sulfide gas. That is to say, the first state of the intake assembly 2 is the closed state, and the second state is the open state;

[0061] Please refer to Figure 2 , in this embodiment, the intake assembly 2 includes:

[0062] An air inlet 21, fixed on the driving vehicle body 1;

[0063] Inclined plates 22, configured in multiple numbers, circumferentially arranged on the air inlet 21 and all inclined;

[0064] Air intake fans 23, configured in multiple numbers, respectively installed on multiple inclined plates 22, and the number of air intake fans 23 on each inclined plate 22 is the same.

[0065] Among them, when the intake assembly 2 is in the first state, for mining work at this time, hydrogen sulfide gas is relatively concentrated and escapes from the coal seam. Align the air inlet 21 with the mining position, and the air intake fans 23 are in the closed state. Then, the hydrogen sulfide gas is preliminarily sprayed through the first spraying assembly 3, and after completion, it is sprayed again through the second spraying assembly 5 to improve the neutralization effect on the hydrogen sulfide gas and complete the treatment of the hydrogen sulfide gas;

[0066] When the intake assembly 2 is in the second state, at this time, in the event of a local excess of hydrogen sulfide gas concentration in the coal mine (which can be monitored by an intrinsically safe explosion-proof portable gas detector), by turning on the intake fan 23, the intake assembly 2 adsorbs and intakes air from all directions at the location with excessive concentration, and cooperates with the first spraying assembly 3 for suction, thereby greatly improving the treatment efficiency of hydrogen sulfide gas.

[0067] Please refer to Figure 2 and Figure 5 , in this embodiment, the first spraying assembly 3 includes:

[0068] The first spraying cylinder 31 is fixed on the driving vehicle body 1, and an air inlet is provided on one side thereof close to the intake assembly 2. A first drain port is provided at the bottom of the first spraying cylinder 31;

[0069] The first collection bin 32 is fixed on the driving vehicle body 1 and is located below the first drain port;

[0070] The first filtration bin (not shown in the figure) is fixed on the driving vehicle body 1 and is located below the first collection bin 32;

[0071] The first extraction fan 33 is installed at the middle position of the first spraying cylinder 31;

[0072] The first spraying pipe 34 is fixed above the first spraying cylinder 31 and is communicated with the spraying pump 6;

[0073] The first spray heads 35 are configured to be multiple and are equidistantly arranged on the first spraying pipe 34.

[0074] It should be noted that the air supply direction of the first extraction fan 33 is upward, and the spraying direction of the first spraying pipe 34 is downward, so that the gas 8 and the liquid 9 can be in counterflow, improving the neutralization effect of hydrogen sulfide in the gas 8.

[0075] Please refer to Figure 3 and Figure 5 , as a preferred embodiment, the second spraying assembly 5 includes:

[0076] The fixed bin 51 is fixed on the driving vehicle body 1;

[0077] The second spraying cylinder 52 is fixed in the fixed bin 51 and is communicated with the first end of the connecting pipe 4. The second end of the connecting pipe 4 is arranged adjacent to the first spraying cylinder 31. Sealing baffles are arranged around the barrel opening of the first spraying cylinder 31 and the pipe orifice of the second end of the connecting pipe 4, so that the gas 8 flows into the connecting pipe 4 after being sent out from above the first spraying cylinder 31; a second drain port is provided below the second spraying cylinder 52;

[0078] The second collection bin 53 is fixed within the fixed bin 51 and is located below the second drain opening;

[0079] The second filtration bin 54 is fixed to the driving vehicle body 1 and is located below the second collection bin 53;

[0080] The second extraction fan 55 is installed at the middle position of the second spray cylinder 52;

[0081] The second spray pipe 56 is fixed above the second spray cylinder 52 and is connected to the spraying pump 6;

[0082] The second spray heads 561 are configured in multiple numbers and are equidistantly arranged on the second spray pipe 56;

[0083] The filtration assembly 57 is fixed within the fixed bin 51 and is located above the second spray heads 561;

[0084] The adsorption plate 58 is fixed within the fixed bin 51 and is located above the filtration assembly 57;

[0085] The air outlet 59 is opened on the upper end surface of the fixed bin 51.

[0086] It should be noted that the air supply direction of the second extraction fan 55 is upward, and the spraying direction of the second spray pipe 56 is downward, so that the gas 8 and the liquid 9 can be counteracted, improving the neutralization effect on hydrogen sulfide in the gas 8. Moreover, the neutralized gas 8 can remove particulate impurities in the gas 8 through the filtration assembly 57, and the remaining harmful gases in the gas 8 can be adsorbed through the adsorption plate 58, thereby improving the cleanliness of the gas 8 when it is discharged and enhancing the ventilation effect.

[0087] Please refer to Figure 2 and Figure 3 , as a preferred embodiment, the bottoms of the first collection bin 32 and the second collection bin 53 are both inclined.

[0088] That is to say, the first collection bin 32 and the second collection bin 53 can buffer the first filtration bin and the second filtration bin 54, thereby preventing the liquid 9 mixed with solids from damaging the first filtration bin and the second filtration bin 54.

[0089] Please refer to Figure 4 , as a preferred embodiment, the filtration assembly 57 includes:

[0090] The frame 571 is fixed within the fixed bin 51;

[0091] The guide posts 572 are configured in four numbers and are fixed within the fixed bin 51;

[0092] The filter plate 1 573 is configured as two, each of which is slidably disposed on the four guide posts 572;

[0093] The second filter plate 574 is configured as two, each of which is slidably disposed on the four guide pillars 572 and is staggered with the two first filter plates 573;

[0094] The oscillation spring 575 is configured as a plurality of springs, all of which are sleeved on the guide column 572 and located between the filter plate 1 573 and the filter plate 2 574 .

[0095] That is to say, when the gas 8 flows upward, it pushes the filter plate 1 573 and the filter plate 2 574, and causes the filter plate 1 573 and the filter plate 2 574 to oscillate through the oscillation spring 575, thereby oscillating and filtering the gas 8 to remove particulate impurities in the gas 8; it should be noted that the filter plate 1 573 and the filter plate 2 574 can be set to different numbers according to needs.

[0096] As a preferred embodiment, the filter plate 1 573 and the filter plate 2 574 are respectively provided with filter hole 1 and filter hole 2, and the filter hole 1 and filter hole 2 are arranged in an alternating manner.

[0097] It should be noted that the staggered arrangement of filter holes 1 and filter holes 2 can prevent the gas 8 from flowing out directly, thereby increasing the thrust on filter plate 1 573 and filter plate 2 574 and improving the oscillation effect.

[0098] The second filter chamber 54 and the first filter chamber are provided with a receiving plate (not shown in the figure) at the bottom, and the receiving plate is connected to the water outlet 7. The flushed liquid 9 flows from the second filter chamber 54 and the first filter chamber into the receiving plate, and then flows out through the water outlet 7 and merges into the mine water treatment system.

[0099] Specifically, the vehicle body 1 can be driven to move underground in a coal mine, so as to treat local hydrogen sulfide gas, and the state of the air intake component 2 can be switched during different work underground in the coal mine, so as to save energy while treating hydrogen sulfide gas. That is to say, when mining is carried out, the hydrogen sulfide gas is relatively concentrated and escapes from the coal seam. The air intake component 2 is aligned with the mining position, and the air intake component 2 is in a closed state. Then, the hydrogen sulfide gas is preliminarily sprayed by the first spray component 3, and then sprayed again by the second spray component 5 after completion to improve the neutralization effect of the hydrogen sulfide gas. Then, the neutralized gas 8 is filtered by the filter component 57 and discharged from the second spray component 5 to complete the treatment of the hydrogen sulfide gas. When a position where the concentration of hydrogen sulfide gas exceeds the standard appears in the coal mine, the air intake component 2 is opened at this time, so that the air intake component 2 can perform multi-directional air intake to the position where the concentration exceeds the standard, thereby greatly improving the treatment efficiency of the hydrogen sulfide gas.

[0100] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
