Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, and in particular to a micron-level dry fog dust suppression classification management system. Background Art

[0002] The original theory of the "dry mist dust suppression" technology is based on an article titled "Solving the Control of Inhalable Dust" published jointly by the University of Waterloo in Canada and the Colorado School of Mines in the United States in the "Coal Age" magazine: When the water mist particles are similar in size to the dust particles, the probability of adsorption, filtration and condensation is the greatest.

[0003] According to the principles of aerodynamics, when the dust-laden airflow bypasses the droplets, the dust particles will deviate from the surrounding airflow due to inertia and collide with the droplets and be captured. That is, the capture is achieved through the inertial collision, interception, condensation and diffusion of dust particles and droplets. The probability of being captured is related to the droplet diameter and the force applied to the dust.

[0004] If the diameter of the water mist particles is larger than that of the dust particles, the dust will only move with the airflow around the water mist particles, and there will be little or no chance of contact between the water mist particles and the dust particles, and the dust suppression effect will not be achieved; if the water mist particles are similar in size to the dust particles, the dust particles will collide and contact with the water mist particles and stick together when moving with the airflow.

[0005] The applicant has found that the prior art has at least the following technical problems: the existing dust control mostly uses 10μm dry mist to suppress dust. This single control mode makes it impossible for dust above 10μm to settle, making it difficult to achieve the expected dust suppression effect. Summary of the invention

[0006] The purpose of the present invention is to provide a micron-level dry mist dust suppression classification management system to solve the technical problem that the existing dust control in the prior art mostly uses 10μm dry mist to suppress dust. This single management mode causes dust above 10μm to be unable to settle at all, and the expected dust suppression effect cannot be achieved. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided by the present invention are described in detail below.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The present invention provides a micron-level dry fog dust suppression hierarchical management system, comprising a first-level management system, a second-level management system and a third-level management system, which are centered on a dust generating point, surround the dust generating point and are sequentially arranged outside the dust generating point, wherein:

By adopting multi-stage management, dust of different particle sizes on site can be collected, adsorbed and condensed respectively, and finally the effect of comprehensive dust reduction and dust suppression can be truly achieved.

[0032] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0033] The present invention provides a micron-level dry fog dust suppression classification management system. Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, it includes a first-level treatment system 1, a second-level treatment system 2 and a third-level treatment system 3, which are centered on the dust generating point 4, surround the dust generating point 4 and are sequentially arranged outside the dust generating point 4, wherein: the first-level treatment system 1 includes a plurality of first micro-mist nozzles 11, and the diameter of the water mist particles generated by the first micro-mist nozzles 11 is less than 50 μm; the second-level treatment system 2 includes a plurality of second micro-mist nozzles 21, and the diameter of the water mist particles generated by the second micro-mist nozzles 21 is less than 30 μm; the third-level treatment system 3 includes a plurality of third micro-mist nozzles 31, and the diameter of the water mist particles generated by the third micro-mist nozzles 31 is less than 10 μm.

[0034] Through this micron-level dry fog dust suppression graded management system, the dust emitted in an unorganized manner is handled. Since the closer to the dust generation point, the larger the dust particles are, in order to achieve a better dust suppression effect, graded management is adopted on site. According to the principles of aerodynamics, the principles of "cloud" physics and the transport mechanism of Stephen flow, when the water mist particles are similar in size to the dust particles, the probability of adsorption and condensation is the greatest. Through graded management, when the dust particles move with the airflow, they will collide, contact and stick together with the water mist. As the agglomerated dust clusters become larger and heavier, they are easy to fall, achieving the "capture" effect of water mist on the dust. By adopting three-level management, the dust of different particle sizes on site are respectively collected, adsorbed and condensed, and finally the effect of comprehensive dust reduction and dust suppression is truly achieved.

[0035] As an optional implementation, Figure 2 is a schematic diagram of dust particle distribution, such as Figure 2As shown, the dust particles dispersed at the center of the dust generating point 4 are concentrated at about 50μm, accounting for nearly 30% of the total dust on site. In the area about one meter outside the dust generating point 4, the dust particles 41 are concentrated at about 30μm, accounting for nearly 30% of the total dust on site. In the area about two meters outside the dust generating point 4, the dust particles are concentrated at about 10μm. This type of inhalable dust accounts for nearly 40% of the total dust on site.

[0036] Therefore, the first-level treatment system 1 is set to be 0.5m-1m away from the dust generating point, and multiple first micro-mist nozzles with a particle size of less than 50μm are arranged in the inner layer to generate micro-mist of about 50μm; the second-level treatment system 2 is set to be 1m-2m away from the dust generating point. In this embodiment, second micro-mist nozzles with a particle size of less than 30μm are arranged around 1.5m away from the dust generating point to generate micro-mist of about 30μm; the third-level treatment system 3 is set to be 2m-3m away from the dust generating point, and third micro-mist nozzles with a particle size of less than 10μm are arranged around 2.5m away from the dust generating point to generate micro-mist of about 10μm, and the number of the first micro-mist nozzles 11, the number of the second micro-mist nozzles 21, and the number of the third micro-mist nozzles 31 are set in ascending order.

[0037] As an optional implementation, Figure 3 It is a schematic diagram of the working process of this embodiment, such as Figure 3 As shown, the first-level treatment system 1, the second-level treatment system 2 and the third-level treatment system 3 are all connected to the water inlet device 14, the water source treatment device 5 and the water storage tank 6 which are arranged in sequence. The water storage tank 6 is connected to the first micro-mist nozzle 11, the second micro-mist nozzle 21 and the third micro-mist nozzle 31 through pipelines. Specifically, a booster pump 7 is provided in the water storage tank 6.

[0038] As an optional embodiment, the water inlet device 14 is connected to the water storage tank 6 through a pipeline, and the water source treatment device 5 is at least one filter and a pipeline purge, wherein:

[0039] At least one filter is installed at at least one of the water outlet of the water inlet device 14 or the water inlet of the water storage tank 6, and is used to effectively filter the incoming water; a pipe blower is connected to the pipe, and is used to clean the water inlet pipe to avoid the influence of dust reduction and dust suppression effect due to blockage of the water inlet pipe or pollution of the water inlet pipe during use.

[0040] As an optional implementation, the first-level treatment system 1, the second-level treatment system 2 and the third-level treatment system 3 also include an air compressor 8 and an air storage tank 9 connected to the air compressor 8. The compressed air drives the sonic oscillator 113 in the nozzle, and the water in the nozzle is quickly atomized by the sonic oscillator 113. The particle size of the water mist particles depends on the water vapor pressure and the nozzle particle size. In actual use, the existing nozzle particle size on the market can be selected according to actual needs and the required water vapor pressure can be set.

[0041] As an optional implementation, the micron-level dry fog dust suppression graded management system also includes a control system, which includes a main control box 10 , and the main control box 10 controls a central control host 12 and a sub-control box 13 .

[0042] Among them, the central control host 12 controls the booster pump 7, the gas tank 9 and the sub-control box 13, and the main control box 10 remotely controls the sub-control box 13; the sub-control box 13 controls the first micro-mist nozzle 11, the second micro-mist nozzle 21 and the third micro-mist nozzle 31, and generates three specifications of micro-mist through the control of the control system and with the help of micro-mist nozzles of three particle sizes. Since the micro-mist particles and dust particles of the same particle size are easily combined together, the entire particle cluster continues to grow and eventually settles down, thereby capturing, adsorbing and condensing the dust of different particle sizes on site, so as to achieve the purpose of removing dust particles and finally realize intelligent comprehensive dust reduction and dust suppression.

[0043] As an optional implementation, Figure 4 is a schematic diagram of the internal structure of the nozzle, such as Figure 4 As shown, the first micro-mist nozzle 11, the second micro-mist nozzle 21 and the third micro-mist nozzle 31 all include: a nozzle 111, a nozzle resonance chamber 112 and an acoustic wave oscillator 113 arranged in the nozzle resonance chamber 112, wherein the acoustic wave oscillator 113 is driven by compressed air.

[0044] As an optional implementation, the nozzles of the first micro mist nozzle 11, the second micro mist nozzle 21 and the third micro mist nozzle 31 are all universal joint nozzles. The universal joint nozzles are controlled by the sub-control box 13 and the spray direction can be changed at any time according to needs, which is easy to operate and use and has a better dust suppression effect.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
