Description

Technical Field

[0001] The invention relates to a smoke purification system, in particular to an underground cavern smoke purification system. Background Art

[0002] Water conservancy and hydropower projects refer to projects that use water resources for comprehensive management such as power generation, flood control, irrigation, and water supply. During the construction of water conservancy and hydropower projects, a large number of underground caverns will be built, and the underground caverns have few external passages, long lines, many bends, and permanent exhaust and smoke exhaust shafts were formed relatively late. In addition, there are many working faces, which are not conducive to the formation of natural ventilation conditions, resulting in an extremely poor construction working environment during the construction period of the underground caverns. For example, the patent with application number 202121217859.X discloses an atomizing dust removal device for underground mining. When dust treatment is required inside the mine tunnel, the equipment is pushed into the dust removal position by moving the handrail, and the atomizing device and the rotating motor are started. The rotating motor drives the dust collecting fan to rotate so that the external dust is collected by the arc fan plate into the exhaust duct. The exhaust duct inputs the dust-mixed air into the left side of the partition plate, so that the water on the left side of the partition plate can remove the dust mixed in the air, and the air is discharged from the top to complete the dust purification. The atomizing device draws water from the water tank through the water intake pipe for atomizing dust removal, thereby preventing the problem of dust removal using only the atomizing device easily affecting the stability of the mine tunnel structure.

[0003] However, during the construction of underground caverns, especially during blasting operations, not only a large amount of dust will be generated, but also a large amount of harmful gases.

[0023] The processing box 4 includes a processing box body 15, in which a support tube 16 is vertically arranged and perpendicular to the gas flow direction, and a flow channel 17 is horizontally arranged and in the same direction as the gas flow direction. A mounting tube 18 is provided outside the support tube 16, and a plurality of mounting grooves 19 corresponding to the flow channel 17 for mounting the activated carbon adsorption plate 7 are provided in the mounting tube 18, and a limiting seat 20 is provided on the outside of the mounting tube 18, and sealing sleeves 21 corresponding to the support tube 16 and the limiting seat 20 are respectively provided on the inner and outer sides of the mounting groove 19, a gear ring 30 is provided at one end of the mounting tube 18, and a driving wheel 31 for driving the gear ring 30 to rotate is provided in the processing box 4.

[0024] The mounting groove 19 is a stepped groove, and a sealing gasket 22 corresponding to the activated carbon adsorption plate 7 is provided on the mounting groove 19 . A positioning hole 24 for locking the activated carbon adsorption plate 7 is provided on one side of the mounting groove 19 .

[0025] The activated carbon adsorption plate 7 is an activated carbon adsorption plate with an arc-shaped cross section.

[0026] The front and rear ends of the limiting seat 20 are provided with vertical grooves 26 for replacing the activated carbon adsorption plate 7 , and a sealing strip 32 is provided in the vertical groove 26 .

[0027] The locking mechanism comprises a screw rod 27 which is arranged at the rear end of the moving trolley 1 and is perpendicular to the moving trolley 1 , a cushion block 28 is arranged at the lower end of the screw rod 27 , and an adjustment handle 29 is arranged at the upper end of the screw rod 27 .

[0028] Principle of the invention: This application mainly includes two parts: dust treatment and harmful gas absorption. Push this application into the underground cavern. Since the ground inside the underground cavern is not particularly flat, a locking mechanism is provided on the rear side of the mobile trolley 1. By turning the adjustment handle 29, the screw 27 is rotated relative to the mobile trolley 1. The mobile trolley is provided with a screw hole or a sleeve corresponding to the screw, so that the pad is connected to the ground to improve the stability of the mobile trolley. The dust treatment is carried out by spraying the water tank 2 through the atomizer 3 to treat the dust at the tunnel face, and the water mist can absorb part of the acid gas and reduce the content of the acid gas in the air. The atomizer adopts an existing atomizer, and specifically a fog cannon can be used. Since the atomizer is a conventional technical means, it is not described in detail here. Then, the harmful gas is absorbed by the treatment box 4. However, at this time, the air contains a large amount of water mist and the air humidity is high, which will affect the absorption of harmful gases by the activated carbon adsorption plate 7. Therefore, the present application is provided with a condensation mechanism on the rear side of the exhaust fan 10, through which the water mist in the air can be condensed, thereby improving the absorption effect of the activated carbon adsorption plate 7 on harmful gases. The air will flow along the bending partition 13, which is connected to the side wall of the condensation box body 11 by screws. When the water mist encounters the capillary thread 14, it will condense into water droplets and fall. The capillary thread can be installed by drilling holes on the partition 13 and then gluing it. It is absorbed by the hygroscopic particles 12, and the hygroscopic particles can further reduce the humidity in the air. The hygroscopic particles can be calcium chloride particles. The gas after moisture absorption will be sent to the treatment box 4 for treatment. A support tube 16 is provided in the treatment box body 15. The support tube 16 is provided with a mounting tube 18 that can rotate relative to the support tube 16. The mounting tube 18 drives the driving wheel on the drive shaft to rotate through an external motor, so that the driving wheel 31 is combined with the gear ring 30 to drive the mounting tube 18 to rotate, so that the activated carbon adsorption plate 7 on the mounting tube 18 is aligned with the flow channel 17. This can be manually observed through the vertical groove or further set up an encoder to detect and realize the angle determination. The sealing sleeve 21 can be offset with the limit seat 20 and the mounting tube 18 to form a closed channel. The exhaust gas needs to pass through the activated carbon adsorption plates 7 on the left and right sides of the flow channel 17 in turn to improve the absorption effect of harmful gases. The harmful gas detector 8 in the air outlet pipe 6 can detect the content of harmful gases after treatment in the treatment box 4. The harmful gas detector is a directly purchased harmful gas detector, and is further an all-in-one harmful gas detector. When the harmful gas detector 8 detects that the harmful gas exceeds the standard, the information can be fed back to the operator, so that the operator controls the motor to rotate the installation cylinder 18, so that the activated carbon adsorption plates 7 at both ends of the flow channel 17 are replaced, reducing downtime and improving the treatment efficiency of harmful gases. The number of activated carbon adsorption plates 7 is an even number. During the operation, the activated carbon adsorption plates 7 can be replaced through the vertical grooves 26 at the front and rear ends of the limit seat 20, and the activated carbon adsorption plates 7 can be removed to achieve rapid replacement of the activated carbon adsorption plates 7.Under the action of the atomizer 3 and the treatment box 4 of the present application, the dust and harmful gases in the underground cave are absorbed, reducing the harm to the operators.
