Description

Technical Field

[0001] The present invention belongs to the field of separation technology, and specifically relates to separating dispersed particles from gas, air or steam by using liquid as a separating agent, and especially relates to a dust treatment method for a vehicle-mounted dust suppressor under operating conditions in severe cold climates in the north and a vehicle-mounted fog and snow cannon dust suppressor using the method. Background Art

[0002] Serious dust pollution will be generated during the mining, transportation and loading and unloading of mineral resources; the sources of dust pollution in mines are complex, and the main links are dust on the surface of coal piles in coal storage yards, dust in the process of stacking and taking ore materials, natural wind dust and road dust. For example, when cars unload ore, the ore falls under the action of gravity and wind, causing dust. In the case of stacking in the mine, dust is generated on the surface of the coal pile under the action of wind. When stackers and reclaimers are performing stacking operations, dust is easily generated under the disturbance of the mechanical power of the stackers and reclaimers.

[0003] In the related technology, a fog and snow cannon integrated all-weather multifunctional dust suppression vehicle suitable for the severe cold regions in the north is used; specifically, in order to suppress dust, combined with local climatic conditions, according to the main mining process and seasonal operation characteristics of the open-pit mining area, a fog and snow cannon integrated dust suppression vehicle is used, which can flexibly switch the fog cannon / snow cannon spray mode according to the ambient temperature to perform all-weather multifunctional dust suppression operations. At the same time, the multifunctional dust suppression vehicle integrates the functions of the generator set, remote intelligent control equipment, large-scale dust removal and haze reduction snowmaking sprayer, long-distance high-pressure fire water cannon, backup power supply box, severe cold antifreeze heating auxiliary accessories, etc., to adapt to the multifunctional requirements of open-pit coal mines and local climatic conditions. Among them, the vehicle-mounted system integrates the modular technology of atomization water-saving function and winter low-temperature operation function. The fog cannon device can take into account both efficient wetting and water-saving dust suppression performance. The snow cannon device can expand a large amount of liquid water into high-pressure atomized ice crystals. According to the dust suppression efficiency and water-saving performance under different ambient temperatures, a multifunctional vehicle-mounted fog and snow cannon integrated machine and new dust suppressant technology suitable for all-weather dust suppression operations are adopted. In summer, mines use multi-point humidification spray to suppress dust and reduce water consumption; in winter, snow spray dust suppression function is realized to make up for the window period of water spray dust suppression measures in severe winter, and solve the dust pollution control problem that is difficult to take into account in the strong sunshine and arid areas in the north. However, in the above scheme, centrifugal atomization nozzles are generally used for liquid atomization, and some undissolved dust suppressant particles are easy to block the centrifugal atomization nozzles.

[0004] Therefore, how to solve the technical problem that undissolved dust suppressant particles easily clog the centrifugal atomizing nozzle is a technical problem that technical personnel in this field urgently need to solve.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0035] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] like Figure 1 As shown, at least one embodiment provides a dust treatment method for a vehicle-mounted dust suppressor, which includes: conveying the dust suppressant aqueous solution in the insulated storage tank 3 to the fog cannon 5 through a pressurized water pump 6; receiving the dust suppressant aqueous solution through the nozzle ring tube 7 of the fog cannon 5; atomizing the dust suppressant aqueous solution into water mist droplets through the centrifugal atomizing nozzle 8 of the nozzle ring tube 7; spraying the water mist droplets through the axial flow fan 51 of the fog cannon 5 to bond with dust particles in the air; adjusting the posture of the fog cannon 5 by rotating the hydraulic support 4; collecting and discharging undissolved dust suppressant particles through the centrifugal atomizing nozzle 8.

[0037] In this embodiment, the pressurized water pump 6 generates a high pressure of 12-20 Bar for the dust suppressant aqueous solution, and then sprays 20-400µm water mist droplets from the centrifugal atomizing nozzle 8, so that the mist and dust particles adhere to each other, adsorb and aggregate, and settle under the action of their own gravity; among them, if the mist particles are close in size to the dust particles, the dust particles will collide and contact with the mist particles and stick together when moving with the airflow, and the smaller the mist particles, the greater the probability of aggregation, and as the aggregated dust clusters become larger and heavier, the dust clusters will accelerate their fall.

[0038] In one application scenario, in winter, the fog cannon 5 is replaced with a snow cannon; specifically, during dust suppression operations in winter, the insulation functions of the insulated liquid storage tank 3 and the built-in stainless steel pipe are turned on, tap water or a dust suppressant aqueous solution is injected into the insulated liquid storage tank 3, and the pressurized water pump 6 sends the dust suppressant aqueous solution to the snow cannon barrel through the built-in stainless steel pipe. The water mist sprayed from the centrifugal atomizing nozzle 8 is made into ice crystal particles by the ice maker in the snow cannon and sprayed out.

[0039] In some embodiments, the method of collecting and discharging undissolved dust suppressant particles through a centrifugal atomizing nozzle 8 includes: by tilting the first atomizing plate 822 and the second atomizing plate 823 on both sides of the adjusting block 821 to guide the dust suppressant aqueous solution to flow to both sides at the adjusting block 821; by changing the inclination angle of the first atomizing plate 822 and the second atomizing plate 823 through the outward movement of the adjusting block 821, the dust suppressant aqueous solution is merged to the adjusting block 821.

[0040] In this embodiment, the first atomizing plate 822 and the second atomizing plate 823 in the initial state can guide the undissolved dust suppressant particles to gather to both sides to prevent the scattered accumulation from causing aggravated blockage; when the amount of dust suppressant particles gathered on both sides reaches a certain level, some atomizing holes 822c will be blocked, causing the pressure in the centrifugal atomizing nozzle 8 to increase. At this time, the adjusting block 821 will move outward to change the posture of the first atomizing plate 822 and the second atomizing plate 823, so that the dust suppressant aqueous solution will merge to the adjusting block 821, and at the same time drive the undissolved dust suppressant particles on both sides to gather to the middle adjusting block 821.

[0041] In some embodiments, the method of collecting and discharging undissolved dust suppressant particles through the centrifugal atomizing nozzle 8 further includes: opening the slag discharge channel 812 by moving the adjustment block 821 outward to discharge small particles of dust suppressant.

[0042] In this embodiment, when the slag discharge channel 812 is opened, some small particles of dust suppressant will be directly discharged from the slag discharge channel 812 along with the dust suppressant aqueous solution, but some large particles of dust suppressant will be blocked.

[0043] In some embodiments, the method of collecting and discharging undissolved dust suppressant particles by the centrifugal atomizing nozzle 8 further includes: crushing the large dust suppressant particles in the slag discharge channel 812 by resetting the adjustment block 821 .

[0044] In this embodiment, the blocked large particles of dust suppressant will be crushed during the resetting process of the adjustment block 821, and then discharged along with the dust suppressant aqueous solution, so that the concentration of the sprayed dust suppressant aqueous solution can be compensated.

[0045] like Figure 2 , Figure 3As shown, at least one embodiment also provides a vehicle-mounted dust suppression machine for a dust treatment method for a vehicle-mounted dust suppression machine, which includes: a mobile vehicle 1, on which is mounted a power device 2, an insulated liquid storage tank 3 and a rotating hydraulic support 4; a fog cannon 5, which is arranged on the rotating hydraulic support 4; a pressurized water pump 6; and a control module, which is configured to adjust the posture of the fog cannon 5 by controlling the rotating hydraulic support 4, and is also configured to transport the dust suppressant aqueous solution in the insulated liquid storage tank 3 to the nozzle ring tube 7 of the fog cannon 5 by controlling the pressurized water pump 6, and after being atomized by the centrifugal atomizing nozzle 8 on the nozzle ring tube 7, it is sprayed out through the axial flow fan 51 in the fog cannon 5.

[0046] In this embodiment, the function of the power device 2 is mainly to provide energy for the insulated liquid storage tank 3, the rotating hydraulic support 4, and the pressurized water pump 6; the function of the rotating hydraulic support 4 is mainly to drive the fog cannon 5 to rotate and raise the spray angle; the function of the pressurized water pump 6 is mainly to transport the liquid in the insulated liquid storage tank 3 to the nozzle ring pipe 7 of the fog cannon 5.

[0047] like Figure 4 , Figure 5 As shown, in some embodiments, the centrifugal atomizing nozzle 8 includes: a nozzle body 81, which is provided with a jet channel 811; an atomizing plate group 82, which is arranged at the outlet of the jet channel 811, and includes: a first atomizing plate 822, a second atomizing plate 823 and a vertically arranged adjusting block 821; wherein the first atomizing plate 822 and the second atomizing plate 823 are respectively hinged on both sides of the adjusting block 821, and are both inclined to guide the undissolved dust suppressant particles to gather on both sides of the adjusting block 821.

[0048] In this embodiment, the dust suppressant aqueous solution is diverted by the inclined first atomizing plate 822 and the second atomizing plate 823 so that the undissolved dust suppressant particles gather on both sides, minimizing the impact on the atomizing hole 822c.

[0049] like Figure 6 , Figure 7As shown, in some embodiments, the first atomizing plate 822 and the second atomizing plate 823 both include: an outer plate 822a and an inner plate 822b; wherein one end of the inner plate 822b is slidably disposed in the outer plate 822a, and the other end is hinged to the inner wall of the jet channel 811, and the end of the outer plate 822a away from the inner plate 822b is hinged to the adjusting block 821; a plurality of atomizing holes 822c are provided on the outer plate 822a; when the undissolved dust suppressant particles in the jet channel 811 block part of the atomizing holes 822c, the water pressure in the jet channel 811 increases and pushes the adjusting block 821 outward, so that the first atomizing plate 822 and the second atomizing plate 823 change their inclination direction to guide the undissolved dust suppressant particles to gather from both sides to the adjusting block 821, and at the same time, the outward movement of the adjusting block 821 opens the slag discharge channel 812 on the side wall of the jet channel 811, so that the small particles of dust suppressant located at the adjusting block 821 are discharged through the slag discharge channel 812.

[0050] In this embodiment, when the number of atomization holes 822c blocked by undissolved dust suppressant particles increases, the pressure in the jet channel 811 becomes greater and greater, pushing the adjustment block 821 to move outward to change the posture of the first atomization plate 822 and the second atomization plate 823, so that the first atomization plate 822 and the second atomization plate 823 guide the dust suppressant aqueous solution to move toward the adjustment block 821 located in the middle, thereby driving the undissolved dust suppressant particles to move toward the adjustment block 821 in the middle.

[0051] like Figure 8 As shown, in some embodiments, during the resetting process of the adjustment block 821, the adjustment block 821 crushes the large particles of dust suppressant in the slag discharge channel 812, so that the crushed dust suppressant particles are sprayed out along with the dust suppressant aqueous solution to compensate for the concentration of the sprayed dust suppressant aqueous solution.

[0052] Specifically, a rolling roller 821 a is provided on the lower surface of the adjusting block 821 , and a slag discharge gap 812 b is left between the rolling roller 821 a and the bottom surface of the slag discharge channel 812 .

[0053] In this embodiment, if large particles of dust suppressant are not effective if discharged directly, they need to be crushed by the crushing roller 821a before being discharged, so that small particles of dust suppressant are mixed with the dust suppressant aqueous solution and sprayed out to compensate for the concentration of the sprayed dust suppressant aqueous solution.

[0054] In some embodiments, the slag discharge channel 812 is opened on the bottom surface of the jet channel 811; the lower end of the adjustment block 821 extends into the slag discharge channel 812 to block the slag discharge channel 812; when the water pressure in the jet channel 811 increases, the adjustment block 821 moves outward to open the slag discharge channel 812.

[0055] In this embodiment, before the first atomizing plate 822 and the second atomizing plate 823 have a merging effect on the dust suppressant aqueous solution, the regulating block 821 always blocks the slag discharge channel 812 .

[0056] In some embodiments, a mounting rod 813 is disposed in the jet channel 811 ; the adjustment block 821 is connected to the mounting rod 813 via a spring 814 so that the adjustment block 821 can be reset.

[0057] Regarding the implementation process of the dust treatment method for the vehicle-mounted dust suppression machine, please refer to the relevant discussion in the above embodiment, which will not be repeated here.

[0058] To sum up, the dust treatment method for the vehicle-mounted dust suppressor and the first atomizing plate 822 and the second atomizing plate 823 of the vehicle-mounted dust suppressor using the method can guide the undissolved dust suppressant particles to gather to both sides when they are in the initial state, so as to prevent the accumulation of dust suppressant particles on both sides from causing increased blockage; when the amount of dust suppressant particles gathered on both sides reaches a certain level, some atomizing holes 822c will be blocked, so that the pressure in the centrifugal atomizing nozzle 8 will increase, and at this time, the adjusting block 821 will move outward to change the posture of the first atomizing plate 822 and the second atomizing plate 823, so that the dust suppressant aqueous solution will merge to the adjusting block 821, and at the same time drive the undissolved dust suppressant particles on both sides to gather to the adjusting block 821 in the middle.
