Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a filter device for rapid deposition of waste gas. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. It has a wide range of sources and complex composition (including but not limited to particulate matter (e.g., smoke and dust) and gaseous pollutants (e.g., sulfur dioxide, nitrogen oxides, and carbon monoxide)). Direct emission of waste gas poses a serious threat to the environment and human health. Therefore, we urgently need a filtration device for rapid deposition of waste gas.

[0003] Currently, the filtration of exhaust gas involves directly passing the exhaust gas through a filtration mechanism (i.e., a filter element). This operation will affect the filtration efficiency of the exhaust gas. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problem that the direct filtration of waste gas affects its filtration efficiency, this utility model provides a filtration device for rapid deposition of waste gas. By improving the structure of the filtration device, the waste gas is cooled before filtration to improve the filtration efficiency of the waste gas.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a filter device for rapid deposition of waste gas, comprising: a filter section, a condenser section, a cooling pipe, an inlet pipe, and an outlet pipe. The filter section contains a filter element for filtering waste gas. The condenser section is installed on one side of the filter section and contains a condenser tank. Both the condenser section and the condenser tank are hollow structures, and the filter section and the condenser section are connected through the condenser tank. The cooling pipe is wound around the outside of the condenser tank, with both its inlet and outlet ends extending to the outside of the condenser section. The inlet end of the cooling pipe is connected to the outlet end of a cooling water circulation device, and the outlet end of the cooling pipe is connected to the inlet end of the cooling water circulation device. Cooling water is injected into the cooling pipe for cooling and reducing the temperature of the waste gas to be filtered. The inlet pipe is connected to the condenser section, and the outlet pipe is located on the other side of the filter section and is connected to the outlet end of the filter element.

[0006] Therefore, by using cooling water flowing inside the cooling pipe to cool the exhaust gas in the exhaust gas filtration section, compared with the existing method of directly filtering the exhaust gas, this method has a simple structure and is easy to operate. The cooling process causes pollutants in the exhaust gas to transfer from the gas phase to the solid or liquid phase, so that the exhaust gas can settle quickly in the filtration section, thereby improving the filtration efficiency of the exhaust gas.

[0007] As a further improvement to the above technical solution: multiple filter elements are provided, and the multiple filter elements are arranged in a ring shape with equal spacing. Therefore, the multiple equally spaced ring-shaped filter elements can improve the efficiency of waste gas filtration by allowing waste gas to enter different filter elements for filtration.

[0008] As a further improvement to the above technical solution: the air intake pipe includes a first air intake branch pipe and a second air intake branch pipe, both of which are connected to the condenser section. The radius of the first air intake branch pipe is R1, and the radius of the second air intake branch pipe is R2; wherein R1 > R2. Therefore, different types of air intake branch pipes (i.e., selecting a first air intake branch pipe with radius R1 or a second air intake branch pipe with radius R2) can be selected according to the flow rate of the exhaust gas to be filtered and the filtration requirements.

[0009] As a further improvement to the above technical solution: a first sealing plug is installed on the first intake branch pipe, the first sealing plug being adapted to the first intake branch pipe; a second sealing plug is installed on the second intake branch pipe, the second sealing plug being adapted to the second intake branch pipe. Therefore, after selecting a suitable intake branch pipe, the first intake branch pipe is sealed using the first sealing plug or the second intake branch pipe is sealed using the second sealing plug, to prevent exhaust gas from leaking out through either the first or second intake branch pipe.

[0010] As a further improvement to the above technical solution: the exhaust pipe includes a first exhaust branch pipe and a second exhaust branch pipe, both of which are connected to the outlet end of the filter element. The radius of the first exhaust branch pipe is R3, and the radius of the second exhaust branch pipe is R4; wherein R3 > R4. Therefore, different models of exhaust branch pipes (i.e., selecting a first exhaust branch pipe with a radius of R3 or a second exhaust branch pipe with a radius of R4) can be selected according to the flow rate of the waste gas to be filtered and the filtration requirements.

[0011] As a further improvement to the above technical solution: a third sealing plug is installed on the first exhaust branch pipe, the third sealing plug being adapted to the first exhaust branch pipe; and a fourth sealing plug is installed on the second exhaust branch pipe, the fourth sealing plug being adapted to the second exhaust branch pipe. Thus, after selecting a suitable exhaust branch pipe, the first exhaust branch pipe is sealed using the third sealing plug, or the second exhaust branch pipe is sealed using the fourth sealing plug, to prevent exhaust gas from leaking out through either the first or second exhaust branch pipe.

[0012] As a further improvement to the above technical solution: a partition is provided inside the filter section and at the bottom of the filter element. The partition has multiple first through holes, forming an exhaust space between the filter section and the partition. The exhaust pipe is connected to this exhaust space. The number of first through holes is equal to the number of filter elements, and the outlet end of each filter element is connected to one of the first through holes. Therefore, by providing a partition inside the filter section, sufficient space is provided on the side wall of the filter section to accommodate the exhaust pipe. This avoids the exhaust pipe affecting the overall placement of the filtration device due to its installation at the bottom of the filter section.

[0013] As a further improvement to the above technical solution: the air outlet pipe is installed on the side wall of the filter section.

[0014] As a further improvement to the above technical solution: the radius of the filter section is R5, and the radius of the condenser section is R6; wherein: R5 > R6. Therefore, by using the R5 > R6 design, it is ensured that the filter section has sufficient space to accommodate multiple filter elements, and also sufficient space for exhaust gas filtration.

[0015] As a further improvement to the above technical solution: the bottom of the condenser is connected to the condenser section, and a second through hole is provided at the bottom of the condenser. The condenser section is connected to the filter section through the condenser and the second through hole in sequence.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses cooling water flowing inside the cooling pipe to cool the exhaust gas in the exhaust gas filtration section. Compared with the existing method of directly filtering the exhaust gas, this method has a simple structure and is easy to operate. Through cooling treatment, pollutants in the exhaust gas are transferred from the gas phase to the solid or liquid phase, so that the exhaust gas settles quickly in the filtration section, thereby improving the filtration efficiency of the exhaust gas.

[0018] 2. This utility model has a partition inside the filter section, which provides space on the side wall of the filter section to accommodate the air outlet pipe. This avoids the air outlet pipe affecting the placement of the entire filter device because it is installed at the bottom of the filter section.

[0019] 3. This utility model uses an R5>R6 design to ensure that the filtration section has enough space to accommodate multiple filter elements and also has enough space to filter exhaust gas. Attached Figure Description

[0040] like Figures 1 to 7The diagram shows the preferred embodiment of this utility model. The waste gas rapid deposition filtration device of this embodiment includes: a filtration section 1, a condenser section 2, a cooling pipe 3, an inlet pipe 4, and an outlet pipe 5. The filtration section 1 has a filter element 101 inside, which is used for filtering waste gas. The condenser section 2 is installed on one side of the filtration section 1, and a condenser tank 201 is provided inside the condenser section 2. Both the condenser section 2 and the condenser tank 201 are hollow structures, and the filtration section 1 and the condenser section 2 are connected through the condenser tank 201. The cooling pipe 3 is wound around... The inlet and outlet ends of the cooling pipe 3 extend to the outside of the condenser 201. The inlet end of the cooling pipe 3 is connected to the outlet end of the cooling water circulation device (not shown in the figure), and the outlet end of the cooling pipe 3 is connected to the inlet end of the cooling water circulation device. Cooling water is injected into the cooling pipe 3 to cool and lower the temperature of the waste gas to be filtered. The inlet pipe 4 is connected to the condenser 2, and the outlet pipe 5 is located on the other side of the filter section 1 and is connected to the outlet end of the filter element 101. Thus, the waste gas is cooled by the cooling water flowing in the cooling pipe 3 between the waste gas filters. Compared with the existing method of directly filtering the waste gas, this method has a simple structure and is easy to operate. The cooling treatment causes the pollutants in the waste gas to transfer from the gas phase to the solid or liquid phase, so that the waste gas settles quickly in the filter section 1, thereby improving the filtration efficiency of the waste gas.

[0041] In this embodiment, multiple filter elements 101 are provided, and the multiple filter elements 101 are arranged in a ring with equal spacing. Therefore, the multiple equally spaced ring-shaped filter elements 101 can improve the filtration efficiency of the exhaust gas by allowing it to enter different filter elements 101 for filtration treatment.

[0042] In this embodiment, the intake pipe 4 includes a first intake branch pipe 401 and a second intake branch pipe 402. Both the first intake branch pipe 401 and the second intake branch pipe 402 are connected to the condenser section 2. The radius of the first intake branch pipe 401 is R1, and the radius of the second intake branch pipe 402 is R2; wherein R1 > R2. A first sealing plug 403 is installed on the first intake branch pipe 401, and the first sealing plug 403 is adapted to the first intake branch pipe 401. A second sealing plug 404 is installed on the second intake branch pipe 402, and the second sealing plug 404 is adapted to the second intake branch pipe 402. Therefore, different models of inlet branch pipes can be selected according to the flow rate of the exhaust gas to be filtered and the filtration requirements (i.e., selecting the first inlet branch pipe 401 with a radius of R1 or the second inlet branch pipe 402 with a radius of R2). After selecting the inlet branch pipe, the first inlet branch pipe 401 is sealed by the first sealing plug 403 or the second inlet branch pipe 402 is sealed by the second sealing plug 404 to prevent exhaust gas from leaking out through the first inlet branch pipe 401 or the second inlet branch pipe 402.

[0043] In this embodiment, the air outlet pipe 5 includes: a first air outlet branch pipe 501 and a second air outlet branch pipe 502. Both the first air outlet branch pipe 501 and the second air outlet branch pipe 502 are connected to the outlet end of the filter element 101. The radius of the first air outlet branch pipe 501 is R3, and the radius of the second air outlet branch pipe 502 is R4; wherein: R3 > R4; a third sealing plug 503 is installed on the first air outlet branch pipe 501, and the third sealing plug 503 is adapted to the first air outlet branch pipe 501. A fourth sealing plug 504 is installed on the second air outlet branch pipe 502, and the fourth sealing plug 504 is adapted to the second air outlet branch pipe 502. Therefore, different models of outlet branch pipes can be selected according to the flow rate of the exhaust gas to be filtered and the filtration requirements (i.e., selecting the first outlet branch pipe 501 with a radius of R3 or the second outlet branch pipe 502 with a radius of R4). After selecting the outlet branch pipe, the first outlet branch pipe 501 is sealed by the third sealing plug 503 or the second outlet branch pipe 502 is sealed by the fourth sealing plug 504 to prevent exhaust gas from leaking out through the first outlet branch pipe 501 or the second outlet branch pipe 502.

[0044] In this embodiment, a partition 102 is provided inside the filter section 1 and at the bottom of the filter element 101. The partition 102 has multiple first through holes 103, forming an exhaust space between the filter section 1 and the partition 102. The exhaust pipe 5 is connected to this exhaust space. The number of first through holes 103 is equal to the number of filter elements 101, and the outlet end of the filter element 101 is connected to the first through holes 103. Therefore, by providing a partition 102 inside the filter section 1, sufficient space is provided on the side wall of the filter section 1 to accommodate the exhaust pipe 5. This avoids the exhaust pipe 5 being installed at the bottom of the filter section 1, thus preventing it from affecting the overall placement of the filtration device.

[0045] In this embodiment, the air outlet pipe 5 is installed on the side wall of the filter section 1.

[0046] In this embodiment, the radius of the filter section 1 is R5, and the radius of the condenser section 2 is R6; wherein: R5 > R6.

[0047] In this embodiment, the bottom of the condenser tank 201 is connected to the condenser section 2, and a second through hole 202 is provided at the bottom of the condenser tank 201. The condenser section 2 is connected to the filter section 1 through the condenser tank 201 and the second through hole 202. Thus, by using the design method of R5>R6, it is ensured that the filter section 1 has enough space to accommodate multiple filter elements 101 and enough space to perform exhaust gas filtration.

[0048] The waste gas filtration process of this utility model is as follows: First, in the initial state, the first sealing plug 403 is inserted into the first inlet branch pipe 401, the second sealing plug 404 is inserted into the second inlet branch pipe 402, the third sealing plug 503 is inserted into the first outlet branch pipe 501, and the fourth sealing plug 504 is inserted into the second outlet branch pipe 502; then, the flow rate of the waste gas to be filtered and the filtration requirements determine whether to use the first inlet branch pipe 401 or the second inlet branch pipe 402, or the first outlet branch pipe 501 or the second outlet branch pipe 502 (here, the first inlet branch pipe is selected). (Taking branch pipe 401 and first exhaust branch pipe 501 as examples) Then, connect the first intake branch pipe 401 to the exhaust end of the exhaust gas; finally, start the cooling water circulation device, and the cooling water circulates in the cooling pipe 3. The exhaust gas to be treated flows along the condenser 2, condenser tank 201, filter 1, filter element 101 and exhaust space. During the flow in the condenser tank 201, the exhaust gas is cooled. During the flow in the filter element 101, the exhaust gas is filtered. After filtration, the exhaust gas is discharged through the first exhaust branch pipe 501.

[0049] In summary, this invention uses cooling water flowing in the cooling pipe 3 to cool the exhaust gas in the exhaust gas filtration section. Compared with the existing method of directly filtering the exhaust gas, this method has a simple structure and is easy to operate. The cooling process allows pollutants in the exhaust gas to transfer from the gas phase to the solid or liquid phase, so that the exhaust gas can settle quickly in the filtration section 1, thereby improving the filtration efficiency of the exhaust gas.

[0050] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
