The wet dust removal is a method for purifying gas by fully contacting a washing liquid (generally water) with dust-containing gas and washing dust particles, and although the discharge of the wet dust removal reaches the standard to a certain extent, in the normal use process of the wet dust removal, a large amount of water is required to be used, so that the water resource waste is caused, and the wet dust removal method is difficult to be applied to arid water-deficient coal mine areas in China; and partial wet dust collecting equipment adopts modes such as atomizing and spraying to fall dust in the air current, and the method is lower to the dust collection efficiency of respiratory dust, and the water bath wet dust collector of current single mode forms the big bubble easily after mineral dust gets into liquid for the dust can't fully contact with liquid, leads to the relatively poor effect of getting rid of the dust, and the practicality is lower.

Step three: the dust-containing air current entering the inside of the purified water tank 101 overflows from the air outlet pipe 105 which is arranged unevenly, is mixed with water and rises in the water in the form of dust-containing bubbles, the ultrasonic transducer 108 inside the cleaning vibration plate 107 at the bottom of the purified water tank 101 converts electric signals into high-frequency vibration under the action of high-frequency electric signals generated by the ultrasonic generator inside the explosion-proof electric control system 11, drives the surface of the cleaning vibration plate 107 to vibrate and transmit the vibration to the cleaning liquid inside the purified water tank 101, the cleaning liquid can generate a large amount of cavitation bubbles under the high-frequency vibration, after the rising dust-containing bubbles are contacted with the cavitation bubbles, the high-energy cavitation bubbles break the dust-containing bubbles at the moment of breakage, the broken bubbles are fully contacted with the water, respiratory dust in the bubbles is effectively removed, and the larger dust-containing bubbles are broken into smaller dust-containing bubbles;
and the smaller dust-containing bubbles pass through the porous medium filter plate 109 in the rising process, because the aperture of the porous medium filter plate 109 is smaller, the dust-containing bubbles are further divided in the process of passing through the porous medium filter plate 109, in addition, most dust particles can be attached to the surface of the porous medium filter plate 109 in the process of contacting the dust on the surface of the dust-containing bubbles with the porous medium filter plate 109, and the dust attached to the aperture of the porous medium filter plate 109 is kept clean in the aperture of the porous medium filter plate 109 under the combined action of micro-amplitude vibration of the filter plate and the ultrasonic transducer 108 arranged on the porous medium filter plate 109 under the cleaning action of cavitation bubbles in water, so that the continuous purification effect on the wind flow is improved.
Step four: under the purification effect of the purification system 1, mine dust in the dust-containing air flow is purified and left in water, the purified air flow is cooled and dehumidified by the heat dissipation condensation grid 18, and the air flow cleaned in the process is discharged into the operation area at the rear part of the roadway through the air outlet cylinder 6.
Furthermore, as a preferred embodiment of the present invention, during the operation of the equipment, the circulating water replenishing pipe 102 in the purification system 1 continuously replenishes water into the purification water tank 101, when the liquid level inside the purification water tank 101 is higher than the upper part of the circulating water discharging pipe 103, the water inside the purification water tank 101 flows out through the circulating water discharging pipe 103, enters the next-stage purification water tank 101, the sewage flowing out from the circulating water discharging pipe 103 of the last purification water tank 101 located at the lowest part enters the mud-water separation system at the lower part after circulating through the purification system 1, the mud-water separation device 13 performs mud-water separation on the sewage, the sludge is compressed and discharged to the sludge tank 14 through the sewage discharge channel, the purified water passes through the centrifugal water pump 15, and then circulates to the purification system 1 in the tank 10 through the circulating water return pipe 16 and the circulating water replenishing pipe 102, so as to realize the recycling of water resources and achieve the function of continuous automatic circulation of the equipment.
Furthermore, the electromagnetic three-way valve 17 controlled by the control system is externally connected with the water replenishing pipe 12, so that the liquid level of the water tank in the equipment can be ensured to be stable, and the liquid level of the water tank in the tower type shunt wet purification system can be ensured to be always in a horizontal state under the condition that the ground of the equipment is uneven by the purification water tank 101 of the purification system suspended by four balance slings, so that the highest dust removal efficiency is realized.
The invention provides an ultrasonic tower type shunt wet-type dust removal system applied to a mine roadway driving working face, which can effectively improve the purification treatment air volume of the dust removal system under the condition of not increasing resistance by utilizing a tower type shunt structure, can divide the air flow, reduce the resistance of equipment, and can realize the division of bubbles and increase the contact area to improve the dust removal efficiency by a porous medium filter plate 109 with irregular, small aperture and high porosity, which is arranged in a purification system 1; simultaneously, by utilizing the principles of ultrasonic cavitation and ultrasonic mechanical vibration, two working principles of ultrasonic waves are designed and adopted: cavitation bubbles generated by ultrasonic cavitation can break up rising dust-containing bubbles on one hand, and can clean a mud layer attached to the inside of the porous medium filter plate 109 on the other hand, so that the dust removal efficiency of dust removal equipment is improved, and the dust removal equipment can continuously run, and the micro-amplitude high-frequency vibration of the filter plate can be realized by ultrasonic mechanical vibration, so that sludge is prevented from being attached to the inner wall of the aperture of the filter plate; moreover, the system can realize the cyclic utilization of water resources and the self-cleaning inside the water purification tank 101, so that the water resources can be saved, and the automation degree is high.
In addition, the cleaning vibration plate 107 in the purification system 1 can effectively convert electric energy into mechanical energy, micro-amplitude high-frequency vibration of the cleaning vibration plate 107 is transmitted into water to generate cavitation bubbles, and the high-energy cavitation bubbles can break rising bubbles and clean sludge attached to the pore diameter of the porous medium filter plate 109 when being broken, so that the self-cleaning function in the equipment is realized; in addition, four ultrasonic transducers 108 sealed by a sealing box 110 are fixed on each porous medium filter plate 109, so that the porous medium filter plates 109 can be driven to realize micro-amplitude high-frequency vibration, and larger dust particles are prevented from blocking through holes of the porous medium filter plates 109. When the air flow flows out from the bottom of the purification water tank 101 and moves upwards in a bubble form, the bubbles can be broken under the action of tiny cavitation bubbles, and dust in the bubbles can be partially absorbed by peripheral liquid at the moment of bubble breaking, so that the dust removal efficiency of the equipment is improved; in the process that the dust-containing bubbles pass through the porous medium filter plate 109, the dust particles in the bubbles are attached to the inner surface of the aperture of the filter plate by friction with the inner surface of the aperture of the filter plate, so that the air flow is further purified; and the heat dissipation condensation grid 18 designed at the air outlet effectively reduces the temperature and the humidity of the purified air flow.
