Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment equipment, in particular to a particulate filtering device for industrial waste gas treatment. Background Technique

[0002] Industrial waste gas refers to the general term of various pollutant-containing gases discharged into the air during fuel combustion and production processes in industrial plants. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead sulfate mercury, beryllium compounds, soot and production dust. Discharged into the atmosphere, they will pollute the air. These substances enter the human body through the respiratory tract in different ways. Some directly cause harm, and some have an accumulation effect, which will more seriously harm human health. Different substances will have different effects.

[0003] Some industrial waste gases contain a large amount of particulate matter. Therefore, when filtering and discharging industrial waste gas, it is necessary to filter out the particulate matter in the waste gas. However, some filter tanks only filter out the particulate matter by a simple filter screen, but the filter screen is easily blocked by the particulate matter, so the filter screen needs to be replaced frequently. Most filter screens are troublesome to replace, so the filtering work efficiency is low. Content of the Utility Model

The filter box installation chamber is communicated with the filtering chamber, and a filter box mechanism is installed in the filter box installation chamber;

[0007] The filter box mechanism includes a filter box. The filter box is inserted into the filter box installation chamber. A cavity is provided on the filter box. A filter screen is arranged at the bottom of the cavity of the filter box. The filter screen is located directly below the filtering chamber. One side of the filter box is fixedly connected with a mounting plate. The mounting plate is installed on the side wall of the filter tank. A plurality of sealing rings are sleeved on the outer wall of the filter box on one side of the cavity. The sealing rings are in contact with the inner wall of the filter box installation chamber.

[0008] In addition, the preferred structure is that the filter box installation chamber communicates to the outer wall of the filter tank, and an installation groove is provided at the outer wall of the filter tank where the filter box installation chamber is located.

[0011] In addition, a preferred structure is that a liquid guide cavity is communicated and opened below the installation cavity of the filter box in the filter tank, a drain pipe is arranged at the bottom of the filter tank, and the drain pipe is communicated with the liquid guide cavity.

[0027] In addition, the filter cartridge installation cavity 13 communicates with the outer wall of the filter tank 1. An installation groove 131 is provided at the position where the filter cartridge installation cavity 13 is located on the outer wall of the filter tank 1. An installation plate 41 is installed at the installation groove 131. A plurality of installation holes 132 are symmetrically provided on the installation groove 131. A sealing gasket 133 is provided on the surface of the installation groove 131. The sealing gasket 133 contacts the installation plate 41, and the sealing gasket 133 prevents waste gas from leaking.

[0028] Moreover, on the other side surface of the installation plate 41 away from the filter cartridge 42, handles 411 are symmetrically provided. Through holes 412 are symmetrically provided on one side of the installation plate 41 where the two handles 411 are located. The through holes 412 are coaxial with the installation holes 132. The installation holes 132 and the through holes 412 facilitate the installation of fixing components, thereby fixing the filter cartridge mechanism 4.

[0029] In addition, a liquid guiding cavity 14 is communicated and opened below the filter tank 1 at the position of the filter cartridge installation cavity 13. A drain pipe 15 is provided at the bottom of the filter tank 1. The drain pipe 15 communicates with the liquid guiding cavity 14. The drain pipe 15 facilitates the operator to open it regularly to discharge the chemical agent stored in the liquid guiding cavity 14.

[0030] At the same time, a placement platform 5 is provided on one side of the filter tank 1. An air blower 2 is provided on the placement platform 5. The air blower 2 communicates with the filtering cavity 11. An exhaust fan 3 is provided on the top of the filter tank 1. The exhaust fan 3 communicates with the filtering cavity 11. The air blower 2 is used to input waste gas into the filtering cavity 11, and the exhaust fan 3 is used to discharge the waste gas.

[0031] Among them, a water pump main body 6 is provided on the upper surface of the placement platform 5. A liquid storage tank 7 is connected to the water suction end on one side of the water pump main body 6. A connecting pipe 8 is connected to the water delivery end on the other side of the water pump main body 6. The other end of the connecting pipe 8 away from the water pump main body 6 extends into the filtering cavity 11. A spray pipe 9 is provided on the top of the filtering cavity 11.

The spray pipe 9 is used to spray the chemical agent, thereby spraying it on the waste gas in the filtering cavity 11, so that the particulate matter in the waste gas is carried down by the chemical agent.

[0032] In this embodiment, when filtering particulate matter in industrial waste gas, this filtering device can be used. The industrial waste gas is drawn into the filtering cavity 11 by the air blower 2. At this time, the spray pipe 9 outputs the chemical liquid stored in the liquid storage tank 8 to the spray pipe 9 through the water pump main body 6 and the connecting pipe 8, and the spray pipe 9 sprays the chemical liquid. At this time, the waste gas is drawn from the bottom of the filtering cavity 11 to the upper part by the exhaust fan 3 and then discharged. During the process of the waste gas being drawn out, the chemical liquid sprayed from the spray pipe 9 will contact the waste gas, thereby carrying down the solid particulate matter in the waste gas, and the chemical liquid will also react with some harmful substances in the waste gas, thereby performing chemical reaction filtration.

[0033] Particulates are brought down to the liquid discharge wall 12 by the chemical agent. The particulates flow into the filter cartridge installation cavity 13 along with the chemical agent from the liquid discharge wall 12 and enter the cavity of the filter cartridge 42. While the chemical agent passes through the filter screen 421, the particulates are blocked in the cavity of the filter cartridge 42, thus preventing the particulates from clogging the liquid discharge pipe 15.

[0034] The operator can regularly replace the filter cartridge mechanism 4. After removing the fixing component installed at the through hole 412, the filter cartridge mechanism 4 can be pulled out of the filter cartridge installation cavity 13 as a whole through the handle 411, so as to clean the cavity of the filter cartridge 42. The sealing ring 43 and the sealing washer 133 can prevent the leakage of waste gas.

[0035] In the present utility model, the chemical liquid agent is sprayed by the spray pipe 9 arranged in the filter tank 1, and the particulates in the industrial waste gas in the filter cavity 11 are brought down to the lower part, and then flow down from the liquid discharge wall 12. The arranged filter cartridge structure 4 can effectively filter out the particulates in the chemical liquid agent, which is convenient for the operator to clean regularly and prevent the liquid discharge pipe 15 from being blocked. Such a filter pipe 1 can effectively filter the particulates in the industrial waste gas, and the cleaning of the particulates is also relatively convenient.

[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
