Description

Technical Field

[0001] The utility model relates to the field of tail gas purification, and particularly relates to an anti-static fiberglass tail gas treatment device. Background Art

[0002] The tail gas treatment device is used to treat tail gas. It conveys the tail gas to a spray tower through an air duct for purifying the tail gas. However, static electricity will be generated when the tail gas rubs against the inner walls of the spray tower and the air duct. And since the tail gas contains flammable and explosive gases, the accumulation of static electricity will pose a fire risk.

[0003] A patent document with the Chinese application number 202221164186.0 and the publication date of January 6, 2023 discloses a spray device for eliminating static electricity in an air duct, which includes a spray tower, a main air duct and a branch air duct. The lower end of the main air duct is communicated with the air inlet of the spray tower. The main air duct includes a plastic main air duct and a metal main air duct. The branch air duct is communicated with the plastic main air duct, and the plastic main air duct is communicated with the metal main air duct. The metal main air duct is connected with a grounding wire to conduct static electricity through the grounding wire.

[0004] This spray device conveys gas through the main air duct. The main air duct includes a metal main air duct and a plastic main air duct. Static electricity will be generated when the waste gas rubs against the plastic main air duct and the metal main air duct. The static electricity at the plastic main air duct cannot be conducted out, which will lead to the accumulation of static electricity. Only one grounding wire is connected to the metal main air duct, and the static electricity generated at different positions of the metal main air duct is conducted out through this grounding wire, and the efficiency of conducting static electricity is low. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide an anti-static fiberglass tail gas treatment device. The entire areas of the tower body and the inner wall of the air duct are covered with a conductive layer, and the static electricity generated at any position on the tower body and the air duct is transmitted into the diversion layer and conducted out through a conductive member. The efficiency of conducting static electricity is improved by increasing the number of conductive members. At the same time, two or more conductive members are arranged at equal intervals along the height direction of the tower body. In this way, the conductive members are evenly distributed along the height direction of the tower body, and the static electricity generated at different positions can be guided to the nearest conductive member to achieve the rapid conduction of static electricity.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An anti-static fiberglass tail gas treatment device described in the present utility model includes a spray tower and an air duct. The spray tower includes a tower body, and the tower body and the air duct are made of fiberglass. The fiberglass includes a conductive layer, a structural layer, and a protective layer stacked from the inside out; the air duct is connected to the air inlet of the tower body, and the conductive layer of the air duct contacts the conductive layer of the air inlet; two or more installation holes are provided on the tower body, and the installation holes are equidistantly spaced along the height direction of the tower body; a conductive member is provided in the installation hole, one end of the conductive member contacts the conductive layer, and the other end of the conductive member is connected with a wire, and a sealing layer is covered at the connection between the conductive member and the tower body.

[0008] Preferably, the air duct and the air inlet of the tower body are connected by a conductive flange. One end of a conductive flange extends into the air inlet and contacts the conductive layer of the air inlet, and the other end of the conductive flange extends into the air duct and contacts the conductive layer of the air duct. The adjacent ends of the two conductive flanges abut against each other.

[0009] Preferably, a wire is connected to the conductive flange.

[0010] Preferably, the conductive layer includes a first conductive layer and a second conductive layer, and the second conductive layer is arranged outside the first conductive layer.

[0011] Preferably, the first conductive layer and the second conductive layer are carbon fiber felt conductive layers or graphite conductive layers.

[0012] Preferably, the first conductive layer is a carbon fiber felt conductive layer.

[0013] Preferably, the second conductive layer is a graphite conductive layer.

[0014] Preferably, the first conductive layer, the second conductive layer, the structural layer and the protective layer are fixed by bonding.

[0015] The beneficial effects of an anti-static fiberglass tail gas treatment device described in the present utility model compared with the prior art are mainly reflected in:

[0016] The tower body and the air duct are made of fiberglass. In the fiberglass, static electricity is guided by the conductive layer, the fiberglass is supported by the structural layer, and the structural layer is protected by the protective layer. The conductive layer covers all areas of the inner walls of the tower body and the air duct, and the static electricity generated at any position on the tower body and the air duct is transmitted to the diversion layer. Through the connection between the conductive member and the conductive layer, the static electricity generated in the air duct or the tower body is led out; a sealing layer is provided at the connection between the conductive member and the tower body to prevent the tail gas from escaping from the connection between the conductive member and the tower body and improve the sealing effect between the conductive member and the tower body; there are two or more conductive members, and the efficiency of leading out static electricity is improved by increasing the number of conductive members; at the same time, two or more conductive members are equidistantly spaced along the height direction of the tower body, so that the conductive members are evenly distributed along the height direction of the tower body, and the static electricity generated at different positions can be guided to the nearest conductive member to realize the rapid leading out of static electricity.

[0017] By setting up a conductive flange to connect the air duct and the air inlet, the connection strength between the air duct and the tower body is enhanced. At the same time, the conductive flange contacts the conductive layer, and the adjacent ends of the two conductive flanges abut against each other, thus increasing the contact area between the air duct and the air inlet, thereby increasing the conductive area and improving the conductive efficiency. Through the connecting wire, the static electricity generated in the air duct can be directly led out through the wire, reducing the static electricity transmitted into the tower body; and further accelerating the discharge of the static electricity in the tower body.

[0018] By setting up two layers of diversion layers to contact the diversion part at the same time, a part of the static electricity is transmitted from the first diversion layer to the diversion part, and another part of the static electricity is transmitted from the first diversion layer to the second diversion layer and then from the second diversion layer to the diversion part, improving the diversion effect.

[0019] The carbon fiber felt and graphite have high electrical conductivity, corrosion resistance and high temperature resistance. By setting up a carbon fiber felt conductive layer and a graphite conductive layer, the conductive effect is good. At the same time, there are corrosive substances in the tail gas. By setting up a corrosion-resistant carbon fiber felt conductive layer and a graphite conductive layer, the service life of the conductive layer is prolonged. The carbon fiber felt conductive layer, between the graphite conductive layers, and the structural layer and the protective layer are adhesively fixed, with good stability.

[0020] In the present utility model, the entire inner wall areas of the tower body and the air duct are covered by the conductive layer, and the static electricity generated at any position on the tower body and the air duct is transmitted into the diversion layer and led out through the conductive part; the discharge efficiency of the static electricity is improved by increasing the number of conductive parts; at the same time, two or more conductive parts are arranged at equal intervals along the height direction of the tower body, so that the conductive parts are evenly distributed along the height direction of the tower body, and the static electricity generated at different positions can be guided to the nearest conductive part to achieve the rapid discharge of the static electricity.

[0029] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used in the present utility model are only for the purpose of illustration.

[0030] This embodiment provides an anti-static FRP tail gas treatment device, as Figures 1-5 shown, including a spray tower 1 and an air duct 2. The spray tower 1 includes a tower body 11. The tower body 11 and the air duct 2 are made of FRP. The FRP includes a conductive layer 31, a structural layer 32 and a protective layer 33 which are stacked from the inside out; static electricity is guided by the conductive layer 31, the FRP is supported by the structural layer 32, and the structural layer 32 is protected by the protective layer 33.

[0031] The air duct 2 is connected to the air inlet 12 of the tower body 11, and the conductive layer 31 of the air duct 2 is in contact with the conductive layer 31 of the air inlet 12; the current generated in the air duct 2 is guided into the tower body 11; the conductive layer 31 covers the entire inner wall area of the tower body 11 and the air duct 2, and the static electricity generated at any position on the tower body 11 and the air duct 2 is transferred to the guiding layer.

[0032] There are more than two mounting holes (not shown in the figure) provided on the tower body 11, and the mounting holes are arranged at equal intervals along the height direction of the tower body 11; a conductive member 4 is provided in each mounting hole, one end of the conductive member 4 is in contact with the conductive layer 31, and the other end of the conductive member 4 is connected with a wire (not shown in the figure). Through the connection between the conductive member 4 and the conductive layer 31, the static electricity generated in the air duct 2 or the tower body 11 is led out.

[0033] A sealing layer 5 is covered at the connection between the conductive member 4 and the tower body 11. This can prevent the exhaust gas from escaping from the connection between the conductive member 4 and the tower body 11 and improve the sealing effect between the conductive member 4 and the tower body 11. In this embodiment, the sealing layer 5 is resin. In this embodiment, the mounting hole is a threaded hole, and the conductive member 4 is a bolt, so that the conductive member 4 can be detachably arranged in the tower body 11, which is convenient for replacement and has good stability. There are more than two conductive members 4. By increasing the number of conductive members 4, the efficiency of leading out static electricity is improved; at the same time, more than two conductive members 4 are arranged at equal intervals along the height direction of the tower body 11, so that the conductive members 4 are evenly distributed along the height direction of the tower body 11, and the static electricity generated at different positions can be guided into the nearest conductive member 4 to achieve the rapid leading out of static electricity.

[0034] In this embodiment, the air duct 2 and the air inlet 12 of the tower body 11 are connected by a conductive flange 6, and the conductive flange 6 is a metal flange; one end of a conductive flange 6 extends into the air inlet 12 and is in contact with the conductive layer 31 of the air inlet 12, and the other end of the other conductive flange 6 extends into the air duct 2 and is in contact with the conductive layer 31 of the air duct 2, and the adjacent ends of the two conductive flanges 6 abut against each other. By providing the conductive flange 6 to connect the air duct 2 and the air inlet 12, the connection strength between the air duct 2 and the tower body 11 is improved. At the same time, the conductive flange 6 is in contact with the conductive layer 31, and the adjacent ends of the two conductive flanges 6 abut against each other, so that the contact area between the air duct 2 and the air inlet 12 is increased, thereby increasing the conductive area and improving the conductive efficiency.

[0035] In a preferred embodiment, a wire (not shown in the figure) is connected to the conductive flange 6. By connecting the wire, the static electricity generated in the air duct 2 can be directly led out through the wire, reducing the static electricity transmitted into the tower body 11; further accelerating the leading out of static electricity in the tower body 11.

[0036] The conductive layer 31 includes a first conductive layer 311 and a second conductive layer 312, and the second conductive layer 312 is arranged outside the first conductive layer 311. By providing two layers of diversion layers in contact with the diversion member at the same time, a part of the static electricity is transmitted from the first diversion layer to the diversion member, and another part of the static electricity is transmitted from the first diversion layer to the second diversion layer and then from the second diversion layer to the diversion member, improving the diversion effect; avoiding static electricity accumulation.

[0037] The first conductive layer 311 is a carbon fiber felt conductive layer or a graphite conductive layer; the second conductive layer 312 is a carbon fiber felt conductive layer or a graphite conductive layer. In this embodiment, the first conductive layer 311 is a carbon fiber felt conductive layer; the second conductive layer 312 is a graphite conductive layer. Carbon fiber felt and graphite have high electrical conductivity, corrosion resistance, and high temperature resistance. By providing a carbon fiber felt conductive layer and a graphite conductive layer, the conductive effect is good. At the same time, there are corrosive substances in the tail gas. By providing a corrosion-resistant carbon fiber felt conductive layer and a graphite conductive layer, the service life of the conductive layer 31 is extended. The carbon fiber felt conductive layer, the graphite conductive layer, the structural layer, and the protective layer are adhesively fixed, and the stability is good.

[0038] Specifically, the structural layer 32 is a resin layer, and the protective layer 33 is a gel coat layer; the carbon fiber felt conductive layer is made by mixing conductive epoxy resin and carbon fiber felt; the graphite conductive layer is made by mixing conductive epoxy resin and graphite. The carbon fiber felt conductive layer, the graphite conductive layer, the structural layer 32, and the protective layer 33 are adhesively fixed by resin. The conductive epoxy resin and the gel coat are prior arts and will not be elaborated here.

[0039] An exhaust port 13 is provided at the top of the tower body 11. The air inlet 12 is provided near the bottom of the tower body 11 and is inclined downward from the input end to the output end of the air inlet 12 along the height direction of the tower body 11. The air inlet 12 is inclined. The tail gas input later will push the front tail gas to move towards the bottom of the tower body 11. At the same time, the flow direction of the tail gas input from the air inlet 12 is opposite to the flow direction of the tail gas floating from the bottom of the tower body 11, thereby slowing down the flow speed of the tail gas, reducing the overall speed of the tail gas in the spray tower, enabling the tail gas to fully contact and react with the liquid, and at the same time reducing the impact of the tail gas on the spray tower by slowing down the flow rate of the tail gas.

[0040] Two or more spray devices 15 are provided inside the tower body 11 from the top of the tower body 11 to the bottom of the tower body 11, and the two or more spray devices 15 are spaced apart along the height direction of the tower body 11.

[0041] The spray device 15 includes a packing layer 151 and a spray pipe 152 provided above the packing layer 151. An outlet 16 is provided at the bottom of the tower body 11, and the outlet 16 is connected to the spray pipe 152 through a circulation pump 17. The alkaline liquid sprayed through the spray pipe 152 contacts the tail gas to purify the tail gas and separate the harmful substances in the tail gas from the gas. The purified gas is discharged through the exhaust port 13; the packing layer 151 and the spray pipe 152 are both prior arts and will not be elaborated here.

[0042] Above the spray device 15 at the top, there is a demister 14. The demister 14 removes the liquid droplets in the tail gas, separates the gas from the liquid, and then discharges the gas. Below the demister 14, there is also an anti-flushing pipeline 18. The anti-flushing pipeline 18 is connected to the water inlet pipeline 19. The anti-flushing pipeline 18 is provided with more than two anti-flushing nozzles 181 facing the demister 14. By arranging the anti-flushing nozzles 181, the demister 14 is flushed to prevent the demister 14 from being blocked.

Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature.
