TECHNICAL FIELD

[0002] With the rapid development of industry, the dust pollution problem generated in industrial production is increasingly serious, causing great harm to the environment and human health. In order to effectively control dust pollution, various dust removal technologies have emerged, among which wet dust removal technology is widely used due to its unique advantages.
[0003] Wet dust removal is through the contact of liquid, usually water, and dust-containing gas, to combine dust particles with liquid, thereby realizing the separation of dust and gas. In the traditional dust removal method, one dust removal method is to directly pass the dust removal gas into the dust removal liquid, so that the dust removal gas contacts the dust removal liquid during the rising process, and the dust particles in the dust removal gas are adsorbed by the dust removal liquid and separated from the gas, realizing gas dust removal. But because the bubbles produced by the dust removal gas into the dust removal liquid are too large, the actual dust removal gas and dust removal liquid contact surface is small, and the dust removal effect is poor. Another dust removal method is to increase a spraying atomization device in the flow path of the dust removal gas, so that the dust removal liquid droplets contact the dust removal gas, but this scheme needs additional power, and the contact area is related to the particle size and density of water droplets.
[0004] Therefore, how to provide a wet dust removal device that can stably and high-quality filter the dust removal gas, improve the filtering efficiency and quality, and prolong the service life of the equipment is a technical problem that technicians in the field urgently need to solve.

[0046] As Figures 1-10 As shown in the first embodiment of the present application, a wet dust removal device is provided:
[0047] The utility model provides a kind of wet dust removal device, which comprises: main body 1, the bottom of the cavity of the main body 1 is used to store dust removal liquid;First air inlet area 101, gas-liquid mixing area 102, gas-liquid separation area 103 are sequentially arranged in the cavity of the main body 1, wherein the bottom of the first air inlet area 101, the bottom of the gas-liquid mixing area 102, the bottom of the gas-liquid separation area 103 are communicated with the bottom of the cavity of the main body 1, the first air inlet area 101 is provided with dust removal air inlet 104, the gas-liquid separation area 103 is provided with dust removal air outlet 105, the dust removal air outlet 105 is used to communicate with external gas negative pressure device;First gas-liquid mixing port 2 is arranged in the main body 1 and located between the first air inlet area 101 and the gas-liquid mixing area 102, the first gas-liquid mixing port 2 communicates the first air inlet area 101 and the gas-liquid mixing area 102;Mixing channel group 3 is arranged in the main body 1 and located in the gas-liquid mixing area 102, one end of the mixing channel group 3 is communicated with the bottom of the cavity of the main body 1, the other end of the mixing channel group 3 is communicated with the gas-liquid separation area 103, the first gas-liquid mixing port 2 is connected to the lower end of the mixing channel group 3;Overflow port 4 is arranged on the main body 1 and located in the gas-liquid separation area 103;Wherein, the horizontal height of the overflow port 4 is higher than the horizontal height of the bottom of the first air inlet area 101, the bottom of the gas-liquid mixing area 102, the bottom of the gas-liquid separation area 103, the horizontal height of the overflow port 4 is higher than the horizontal height of the first gas-liquid mixing port 2.
[0048] In the technical scheme of the wet dust removal device provided in the application, in general, the dust particles in the dust removal gas are adsorbed by the dust removal liquid after contacting the dust removal liquid by introducing the dust removal gas into the dust removal liquid in the main body, so as to realize the dust removal effect on the dust removal gas. Further, the inner cavity of the main body is divided into a first air inlet area, a gas-liquid mixing area and a gas-liquid separation area, and the bottoms of the three areas are communicated with the bottom of the inner cavity of the main body. Under the action of the external gas negative pressure device, the gas-liquid mixing area and the gas-liquid separation area form a negative pressure. The dust removal gas in the first air inlet area enters the gas-liquid mixing area from the first gas-liquid mixing port. Since the horizontal height of the overflow port is higher than that of the first gas-liquid mixing port, the dust removal gas in the first air inlet area mixes with the dust removal liquid in the first air inlet area in the first gas-liquid mixing port and enters the gas-liquid mixing area together, realizing gas-liquid mixing. The dust particles in the dust removal gas are adsorbed by the dust removal liquid, realizing dust removal and purification of the dust removal gas. Further, after the negative pressure of the gas-liquid mixing area and the gas-liquid separation area reaches a certain degree, the liquid level of the dust removal liquid at the bottoms of the gas-liquid mixing area and the gas-liquid separation area rises, and the liquid level of the dust removal liquid in the first air inlet area decreases. When the liquid level of the dust removal liquid in the first air inlet area is lower than the top end of the first gas-liquid mixing port, the air ducts of the first air inlet area and the gas-liquid mixing area are communicated. The dust removal gas in the first air inlet area passes through the first gas-liquid mixing port at high speed under the action of the negative pressure. The dust removal gas passing through the first gas-liquid mixing port at high speed splashes the dust removal liquid in the first gas-liquid mixing port, further promoting the mixing of the dust removal gas and the dust removal liquid, and improving the dust removal effect. Further, the technical scheme of the application is powered by the external gas negative pressure device, avoiding the problem that the air blower is easily damaged in the traditional scheme. The technical scheme provided in the application can stably and high-quality filter the dust removal gas, improve the filtering efficiency and quality, and prolong the service life of the equipment.
[0049] It should be noted that the innovation point of the technical scheme of the application is the structure of the device. The dust removal liquid is only injected into the wet dust removal device in the actual use process. The dust removal liquid needs to be determined according to the actual dust removal object.
[0050] It should be noted that, since the gas-liquid mixing area and the gas-liquid separation area are communicated through the mixing channel group, the gas-liquid mixing area and the gas-liquid separation area have the same negative pressure, under the action of the external gas negative pressure device, the dust removal liquid level at the bottom of the gas-liquid mixing area and the gas-liquid separation area is raised, since the first gas-liquid mixing port is blocked by the dust removal liquid, and the volume of the dust removal liquid in the whole main cavity is relatively unchanged, the dust removal liquid level in the first air inlet area is lowered. The key point of the scheme is that the horizontal height of the overflow port is higher than the horizontal height of the bottom of the first air inlet area, the bottom of the gas-liquid mixing area and the bottom of the gas-liquid separation area, that is, the horizontal height of the bottom of the first gas-liquid mixing partition structure and the second gas-liquid mixing partition structure is lower than the horizontal height of the overflow port, and is lower than the liquid level of the dust removal liquid in the working state.
[0051] It should be noted that, as shown in Figure 5 When the wet dust removal device is in a non-starting state, the horizontal height of the first gas-liquid mixing port is lower than the liquid level of the dust removal liquid.
[0052] Specifically, in the embodiment of the utility model, the device further comprises: an overflow balance tank 5 communicated with the overflow port 4, the overflow balance tank 5 is used to store the overflowed dust removal liquid, and prevent external gas from entering the gas-liquid separation area 103.
[0053] It should be noted that, if the dust removal liquid height inside the main body is higher than the overflow port, the excess dust removal liquid enters the overflow balance tank first.
[0054] Specifically, in the embodiment of the utility model, the overflow balance tank 5 comprises: a liquid storage cavity 501, a balance cavity 502, a balance communication pipe 503, and a liquid outlet 504; the liquid storage cavity 501 is located at the upper end of the balance cavity 502; the upper end of the balance communication pipe 503 communicates with the bottom of the liquid storage cavity 501, the lower end of the balance communication pipe 503 penetrates into the bottom of the balance cavity 502, and the lower end of the balance communication pipe 503 communicates with the balance cavity 502; the liquid outlet 504 is arranged on the side wall of the balance cavity 502, and the liquid outlet 504 communicates with the outside; the horizontal height of the liquid outlet 504 is higher than the horizontal height of the lower end of the balance communication pipe 503.
[0055] It should be noted that the excess dust removal liquid discharged from the overflow port first enters the liquid storage cavity, and under the action of the balance communication pipe, the liquid levels inside and outside the balance communication pipe are consistent when the equipment is not started, and after the equipment is started, although the liquid level in the main body cavity is raised, causing the excess discharged dust removal liquid to enter the liquid storage cavity, since the gas-liquid separation zone has a negative pressure, the liquid level of the dust removal liquid inside the balance communication pipe and the liquid storage cavity is higher than the liquid level outside the balance communication pipe, thereby achieving the technical effects of collecting the dust removal liquid discharged from the overflow port in the main body, while preventing external gas from entering the main body through the overflow port and affecting the negative pressure of the gas-liquid separation zone.
[0056] Specifically, in the embodiment of the utility model, the device further comprises: a water replenishing port 106 arranged on the main body 1 and used for introducing dust removal liquid into the main body 1.

[0068] It should be noted that when the equipment is running, the dust removal liquid is accumulated backward, and by sequentially increasing the horizontal height of the plurality of first gas-liquid mixing ports, the resistance of each first gas-liquid mixing port can be balanced.
[0069] Specifically, in the embodiment of the utility model, the first gas-liquid mixing port 2 comprises: an upper plate body 201 and a lower plate body 202; the upper plate body 201 and the lower plate body 202 are oppositely arranged, and the upper plate body 201 and the lower plate body 202 are connected to the inner wall of the main body 1 along the direction perpendicular to the airflow movement, and the upper plate body 201, the lower plate body 202 and the inner wall of the main body 1 constitute a gas-liquid mixing channel.
