Description

Technical Field

[0001] The invention relates to the technical field of coal mining, and in particular to a tunnel ventilation purification treatment device. Background Art

[0002] Tunnel ventilation refers to the technical measures for air flow and exchange in underground mines, tunnels and other tunnels to improve the working environment, ensure working safety and improve construction efficiency. The main purpose of tunnel ventilation is to remove harmful gases, dust, waste heat and other pollutants, provide fresh air, and maintain the air quality in the tunnel to meet the working requirements. However, the polluted air discharged from the tunnel cannot be discharged directly. If it is discharged directly without treatment, it will pose a serious threat to the atmospheric environment and human health, and even cause serious safety accidents such as explosions.

[0003] In the related technology, the exhaust pipe of the tunnel is an important pipeline for discharging polluted air, waste gas, dust and other harmful substances in underground projects such as mines and tunnels. Before the exhaust pipe discharges the polluted air, it needs to pass through some purification equipment, such as dust collectors and absorption towers, to reduce the pollutants discharged into the atmosphere. However, at present, the exhaust pipe is only connected to these purification equipment, and the equipment body is exposed to the outside world without isolation treatment, which seriously reduces the overall safety and convenience of equipment maintenance.

DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] The tunnel ventilation purification treatment device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the tunnel ventilation purification treatment device of the embodiment of the present invention includes a device body 1, the device body 1 has a buffer chamber 101 and a purification chamber 102, and the device body 1 is provided with an air inlet 103, an air outlet 104 and a vent 105.

[0030] The air inlet 103 is provided on the side wall of the buffer chamber 101, and the air inlet 103 is communicated with the buffer chamber 101. The air vent 105 is provided on the side wall shared by the buffer chamber 101 and the clean chamber 102, and the buffer chamber 101 and the clean chamber 102 are communicated through the air vent 105. The air outlet 104 is provided on the side wall of the clean chamber 102, and the air outlet 104 is communicated with the clean chamber 102.

[0031] A purification box 2, a vent pipe 3 and an air outlet pipe 4 are provided in the purification chamber 102. The inlet of the vent pipe 3 is communicated with the vent hole 105, the outlet of the vent pipe 3 is inserted in the purification box 2, the inlet of the air outlet pipe 4 is inserted in the purification box 2, and the outlet of the air outlet pipe 4 is communicated with the air outlet hole 104.

[0032] It is understandable that the air inlet 103 is used to connect the exhaust pipe of the lane, so that the polluted air discharged from the lane flows into the buffer chamber 101 through the air inlet 103 for buffering, plays a certain role in pressure relief, stabilizes the airflow, and avoids the problem of directly impacting the purification box 2 and causing equipment damage. Then, the polluted air flowing into the buffer chamber 101 flows into the purification box 2 through the vent 105 and the vent pipe 3 for purification, and the purified gas is discharged to the external environment through the outlet pipe 4 and the outlet 104.

[0033] Therefore, the purification box 2 is arranged in the purification room 102 to separate it from the external environment. Even if there is a leakage problem in the purification box 2, it will not directly pollute the external environment. It also avoids the influence of the external environment (such as humidity, temperature changes, dust, etc.) on the purification box 2, thereby improving the safety and effectiveness of tunnel ventilation purification.

[0034] In some embodiments, Figure 1 As shown, a maintenance hole is provided on the device body 1, and the maintenance hole is communicated with the purification chamber 102. A sealing component 5 is provided at the maintenance hole, and the sealing component 5 can block the maintenance hole.

[0035] It is understandable that when the purification box 2 leaks or requires maintenance, the sealing assembly 5 is opened to allow maintenance personnel to enter the purification chamber 102 through the maintenance hole to perform operations, thereby ensuring the sealing of the purification chamber 102 while facilitating maintenance of the purification equipment.

[0036] Alternatively, if Figure 1 and Figure 3 As shown, the sealing assembly 5 includes a sealing plate 51, a toothed disc 52 and a rack 53. The sealing plate 51 is rotatably connected to the device body 1 through a hinge or other structure, so that the sealing plate 51 blocks or opens the maintenance hole. The toothed disc 52 is rotatably connected to the sealing plate 51, and the rack 53 is slidably connected to the sealing plate 51. The toothed disc 52 and the rack 53 are meshed, and a slot corresponding to the rack 53 is provided on the wall of the maintenance hole, so that the end of the rack 53 is inserted into the slot and the deflection of the sealing plate 51 is limited.

[0037] When the maintenance hole needs to be opened, the toothed disc 52 is rotated counterclockwise, and the toothed disc 52 drives the rack 53 to slide in a direction away from the slot, so that the end of the rack 53 is disengaged from the slot, thereby releasing the limiting effect on the sealing plate 51 and opening the sealing plate 51. Conversely, when the maintenance hole needs to be blocked, the sealing plate 51 is closed, the toothed disc 52 is rotated clockwise, and the toothed disc 52 drives the rack 53 to slide in a direction close to the slot, so that the end of the rack 53 is inserted into the slot, thereby limiting the movement of the sealing plate 51 under the cooperation of the rack 53 and the slot.

[0038] Specifically, Figure 3 As shown, the toothed disc 52 and the rack 53 are both arranged in the sealing plate 51, and a manual turntable connected to the toothed disc 52 is arranged outside the sealing plate 51, and the manual turntable is used to rotate the toothed disc 52. Thus, the transmission structure is protected.

[0039] Furthermore, if Figure 1 As shown, there are multiple racks 53 and slots in one-to-one correspondence, and the racks 53 are distributed at intervals around the toothed disc 52, thereby improving the reliability of limiting the sealing plate 51.

[0040] In some embodiments, the sealing assembly 5 further includes a sealing gasket which is attached to the wall of the maintenance hole.

[0041] Optionally, the sealing gasket is made of rubber material. When the sealing plate 51 is closed, the sealing plate 51 and the sealing gasket are interference fit, thereby improving the effectiveness of the seal.

[0042] In some embodiments, Figure 2 As shown, there are multiple vent holes 105, and the vent pipe 3 includes a connected collecting section and multiple branch pipe sections, part of the collecting section is inserted in the purification box 2, and the multiple branch pipe sections correspond to the multiple vent holes 105 one by one and are connected.

[0043] It can be understood that the gas in the buffer chamber 101 flows into the corresponding branch pipe sections of the ventilation pipe 3 through the multiple ventilation holes 105, and then enters the purification box 2 through the collection section of the ventilation pipe 3. By providing multiple ventilation holes 105, the gas in the buffer chamber 101 can be uniformly introduced into the ventilation pipe 3, thereby improving the efficiency of gas transportation.

[0044] And, if Figure 2 As shown, a ventilation fan 6 is provided in the vent hole 105, and the ventilation fan 6 is used to guide the polluted air flowing into the buffer chamber 101 into the vent hole 105 and transport it to the purification box 2 through the ventilation pipe 3, so as to further improve the efficiency of gas transportation.

[0045] In some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, a filter plate 7 is provided in the gas outlet pipe 4, and the filter plate 7 is detachably connected to the gas outlet pipe 4. Therefore, by providing the filter plate 7 in the gas outlet pipe 4, the gas is further filtered, and the effectiveness of gas purification is improved.

[0046] Alternatively, if Figure 2 , Figure 4 and Figure 5 As shown, the cross-sectional shape of the air outlet pipe 4 is square, and a mounting groove is provided on the peripheral wall of the air outlet pipe 4, the mounting groove is T-shaped, and a sliding block is provided on the edge of the filter plate 7 to fit in the mounting groove, so that the filter plate 7 can be slidably pulled out or inserted into the air outlet pipe 4, thereby improving the convenience of replacing and cleaning the filter plate 7.

[0047] In some embodiments, Figure 1 and Figure 6 As shown, the device body 1 also has an isolation chamber 106 , which can be connected to the purification chamber 102 through a maintenance hole, and a sealing door 8 is provided on the side wall of the isolation chamber 106 .

[0048] It is understandable that when the purification box 2 or the ventilation pipe 3 has a leakage problem, the ventilation fan 6 stops working, and most of the dirty air is retained in the buffer chamber 101. The staff opens the sealing door 8 to enter the isolation chamber 106, then closes the sealing door 8, and then opens the sealing assembly 5 that blocks the maintenance hole to enter the purification chamber 102. Therefore, by setting up the isolation chamber 106, gas leakage during maintenance operations is reduced.

[0049] Optionally, a detection probe is installed in the purification chamber 102, and an alarm is installed on the outer wall of the device body 1. When the detection probe detects that there is a leakage of polluted gas in the purification chamber 102, the alarm sounds an alarm to remind the staff.

[0050] Furthermore, if Figure 1 and Figure 7 As shown, a return air channel 107 is provided in the device body 1, the inlet of the return air channel 107 is connected to the isolation chamber 106, the outlet of the return air channel 107 is connected to the buffer chamber 101, and an exhaust pump 9 is provided in the return air channel 107, and the exhaust pump 9 is used to draw the gas in the isolation chamber 106 into the return air channel 107 and transport it to the buffer chamber 101.

[0051] When the maintenance work is completed, the polluted gas leaked in the purification chamber 102 and the isolation chamber 106 is transported to the buffer chamber 101 through the return air channel 107 by using the vacuum pump 9. After ensuring that there is no polluting gas in the isolation chamber 106 and the purification chamber 102, the maintenance hole is sealed, the sealing door 8 is opened to leave the isolation chamber 106, and the work is completed.

[0052] Therefore, by utilizing the cooperation between the isolation chamber 106 and the vacuum pump 9, the problem of gas leakage can be further avoided and the safety of the device can be improved.
