DETAILED DESCRIPTION

[0025] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0026] Reference Figure 1 And Figure 2 It can be known that the water bath dust removal device in the utility model comprises:

[0027] The shell 1 is provided with an air outlet 101 at the top and an air inlet 102 at the bottom side;

[0028] The water spraying mechanism 2 comprises a plurality of water spraying pipes 201, which are arranged in the inner cavity of the shell 1 along the height direction of the shell 1, a plurality of spray heads 202 are arranged on each water spraying pipe 201 along the axial direction of the water spraying pipe 201, and the spray heads 202 are arranged to spray water mist into the shell 1;

[0029] The water supply mechanism 3 is used for supplying water into the water spraying pipe 201;

[0030] The baffle 4 is arranged in the shell 1, and a plurality of baffles 4 are arranged above each water spraying pipe 201 one by one, and the plurality of baffles 4 form a baffle air duct 401 for dust gas flow in the shell 1.

[0031] Among them, one water spraying pipe 201 and a plurality of spray heads 202 arranged on the water spraying pipe 201 are arranged between adjacent baffles 4.

[0032] Among them, the dust gas flow enters from the bottom air inlet of the shell 1 and flows upward along the baffle air duct 401 in the shell 1 to the top air outlet of the shell 1.

[0033] It can be understood that the plurality of water spraying pipes 201 arranged at intervals along the height direction of the shell 1 and the plurality of spray heads 202 arranged on the water spraying pipes 201 can continuously spray water mist in the baffle air duct 401 in the entire shell 1. It is worth noting that the baffle passage in the shell 1 increases the flow path of the dust gas flow in the shell 1, thereby increasing the contact time of the dust gas flow with the water mist. Therefore, the dust gas flow can be fully contacted with the water mist in the shell 1.

[0034] Therefore, the plurality of water spraying pipes 201 and the plurality of spray heads 202 arranged on each water spraying pipe 201 form a plurality of layers of water mist filtering zones in the shell 1 along the height direction of the shell 1. At the same time, the baffle air duct 401 in the shell 1 increases the flow path of the dust gas flow. Therefore, it is avoided that the dust particles cannot be fully contacted with the water mist, thereby improving the dust removal efficiency of the water bath dust removal device.

[0035] In some embodiments, the spray head 202 can include a stainless steel spiral spray head 202. The stainless steel spiral spray head 202 can produce uniform liquid distribution and has a large spray angle to form a uniform and fine mist water curtain. Therefore, the water mist sprayed by the stainless steel spiral spray head 202 arranged at intervals along the axial direction of the water spraying pipe 201 can cover every corner of the water spraying pipe 201 located in the baffle air duct 401.

[0036] In some embodiments, referring to Figure 3 It can be seen that the baffle plates 4 are all downwardly inclined, and the sewage collected on the side of the baffle plates 4 facing the air outlet 101 is discharged to the bottom of the shell 1.

[0037] Among them, the first ends of the plurality of baffle plates 4 are connected to the two opposite side walls of the inner cavity of the shell 1 in a staggered manner and are arranged above the water spraying pipes 201 one by one, the second ends extend downwardly and incline to the center between the two opposite side walls and cross the center surface, so that the side of the baffle plate facing the air outlet of the shell 1 can naturally form a drainage slope 402.

[0038] It can be understood that the water droplets collected in the baffle air duct 401 will fall on the drainage slope 402 under the action of gravity, and slide from the baffle plate 4 to the next layer of baffle plate 4, and finally collect on the bottom end surface of the shell 1.

[0039] In some embodiments, referring to Figure 3 It can be seen that the bottom end of the inner cavity of the shell 1 is provided with an inclined drainage slope 103 for discharging the sewage collected at the bottom end of the shell 1 out of the shell 1.

[0040] In some embodiments, referring to Figure 1 It can be seen that the water supply mechanism 3 includes a connecting pipe group and a water pump 301, and the water pump 301 supplies water to the water spraying pipes 201 through the connecting pipe group.

[0041] In some embodiments, the water supply mechanism 3 further comprises a clean water tank 302 for recycling and purifying the dust-removed sewage in the shell 1, and the water pump 301 drives the purified water in the clean water tank 302 to flow into the water spraying pipe 201.

[0042] In some embodiments, a drain pipe 303 is connected between the shell 1 and the clean water tank 302 to drain the sewage in the shell 1 into the clean water tank 302.

[0043] In some embodiments, a drain valve 304 is arranged on the drain pipe 303 to control the on-off state of the drain pipe 303.

[0044] In some embodiments, a water suction pipe is connected between the water pump 301 and the clean water tank 302.

[0045] In some embodiments, the connecting pipe group comprises a branch water pipe 305 and a main water pipe 306, the water inlet of each water spraying pipe 201 is connected with the branch water pipe 305, one end of the main water pipe 306 is connected with the water pump 301, and the other end is connected with the branch water pipe 305.

[0046] In the utility model, the clean water tank 302 recycles the sewage in the shell 1, purifies and discharges it into the clean water storage area of the clean water tank 302, and then the water pump 301 drives the water in the clean water storage area to flow into the water spraying pipe 201 through the connecting pipe group, so as to realize the effective recycling of water.

[0047] It can be understood that the water inlet of the water pump 301 is connected with the clean water storage area of the clean water tank 302 through the water suction pipe, and the water outlet is connected with the main water pipe 306. It is worth noting that the clean water delivered by the water pump 301 into the water supply pipe needs to have sufficient water pressure to enable the water in the water spraying pipe 201 to be sprayed from the stainless steel spiral nozzle 202 and form a uniform water curtain.

[0048] In some embodiments, a condenser 6 is arranged at the air outlet of the shell 1 to reduce the humidity of the dust discharged from the shell 1 and reduce the temperature of the dust airflow.

[0049] In some embodiments, with reference to Figure 3 It can be understood that the inner cavity of the shell 1 is further provided with a partition plate 5, the partition plate 5 is used for dividing the inner cavity into a dust removal cavity 501 and a connecting cavity 502, a plurality of baffles 4 are arranged in the dust removal cavity 501, both ends of each water spraying pipe 201 are located in the dust removal cavity 501 and the connecting cavity 502 respectively, a control valve 203 for controlling the on-off state of each water spraying pipe 201 is arranged on each water spraying pipe 201, and the control valve 203 is located in the connecting cavity 502 to avoid the control valve 203 being washed by the dust airflow and being affected by the external environment of the shell 1, thereby prolonging the service life of the control valve 203.

[0050] Among them, reference Figure 1 It can be seen that the branch water pipe 305 is set in the connecting cavity 502, and the part of each spray pipe 201 with the nozzle 202 is located in the dust removal cavity 501, and the other end passes through the partition plate 5 and is connected to the branch water pipe 305.

[0051] Meanwhile, the slope of the drainage ramp 103 inside the shell 1 gradually decreases from the air inlet of the shell 1 toward the wall opposite the air inlet until it becomes zero.

[0052] Additionally, refer to Figure 1 It is known that the drain pipe 303 is installed on the drainage slope 103 located on the bottom side of the connecting cavity 502 and connected to the dust removal cavity 501. The drain valve 304 on the drain pipe 303 is also located in the connecting cavity 502 and close to the partition plate 5 to avoid too much dust airflow entering the drain pipe 303.

[0053] It is understandable that the inclined arrangement of the drain pipe 303 allows sewage to flow into the water purification tank 302 under the influence of gravity. Of course, in some other embodiments, the drain valve 304 may also be located near the end of the water purification tank 302, but in this case, some dusty airflow will accumulate in the drain pipe 303.

[0054] In this utility model, reference Figure 1 It is known that the second end of the bottom baffle 4 inside the housing 1 is close to the partition plate 5. It is understandable that water droplets sliding down from the upper layer of the housing 1 will first collect at the lowest end of the drainage slope 103 inside the dust removal chamber 501, to prevent the water droplets from flowing out of the housing 1 from the air inlet.

[0055] In some embodiments, the interior of the housing 1 is sprayed with an anti-corrosion and anti-scaling coating to solve the problem of easy scaling inside the housing 1, thereby improving the working efficiency of the water bath dust removal device and reducing the maintenance cost of the device.

[0056] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and all fall within the protection scope of the present invention.
