Description

Technical Field

[0001] The utility model relates to the technical field of waste tire pyrolysis, in particular to an anti-crystallization oil-gas-water seal tank device. Background Art

[0002] The main products of the waste tire pyrolysis process include pyrolysis oil and non-condensable combustible gas. The non-condensable combustible gas is used as fuel for the pyrolysis equipment to continuously supply heat after desulfurization treatment by alkali liquor spraying. As an important link before the use of the non-condensable combustible gas, the water seal tank device plays a role in sealing and preventing backfire.

[0003] However, sometimes due to various reasons such as too high water content in the pyrolysis raw materials, overpressure will occur in the pyrolysis furnace, causing the alkali liquor in the desulfurization process at the front end of the water seal tank to be sent to the water seal tank, and gradually reaching saturation as the alkali liquor accumulates, resulting in crystallization precipitation, and finally blocking the combustible gas outlet hole of the water seal tank. The inability to discharge the non-condensable combustible gas will cause excessive pressure in the entire pyrolysis production line, posing a great production risk. Therefore, when the water seal tank is blocked by crystallization, the machine can only be stopped for cleaning, which is not only time-consuming and laborious, but also delays production and operation, increasing the production cost of restarting ignition and starting up. Therefore, it is necessary to design an oil-gas-water seal tank device that can reduce the probability of crystallization in the water seal tank. Summary of the Utility Model

[0004] In view of the above problems in the prior art, the present application proposes an anti-crystallization oil-gas-water seal tank device, which can reduce the probability of crystallization in the water seal tank.

[0005] The utility model provides an anti-crystallization oil-gas-water seal tank device, which includes a water seal tank body. A circulation pipeline is connected to the bottom of the water seal tank body, and a circulation driving mechanism is installed on the circulation pipeline. The circulation driving mechanism can drive the alkali liquor in the water seal tank body to circulate along the circulation pipeline, and a crystallization net is installed in the circulation pipeline. When the alkali liquor flows through the crystallization net, crystallization precipitation adheres to the crystallization net.

[0006] As a further improvement of the above technical solution:

[0007] In the above anti-crystallization oil-gas-water seal tank device, further, a clamping groove is provided in the circulation pipeline, and the crystallization net is detachably installed in the clamping groove.

[0008] In the above anti-crystallization oil-gas-water seal tank device, further, multiple layers of the crystallization nets are installed at intervals along the extending direction in the circulation pipeline.

[0009] In the above anti-crystallization oil-gas-water seal tank device, further, a heating mechanism is installed on the outer wall of the water seal tank body, and the heating mechanism is used to heat the alkali liquor in the water seal tank body.

[0010] For the above anti-crystallization oil-gas-water seal tank device, further, the heating mechanism is an electric heating tape wrapped around the outer wall of the water seal tank body, and the energized electric heating tape can heat the caustic solution in the water seal tank body.

[0011] For the above anti-crystallization oil-gas-water seal tank device, further, the outer side of the electric heating tape is wrapped with a heat insulation layer.

[0012] The above technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present utility model can be achieved.

[0013] Compared with the prior art, the anti-crystallization oil-gas-water seal tank device provided by the present utility model at least has the following beneficial effects: during use, the circulation driving mechanism drives the caustic solution in the water seal tank body to circulate along the circulation pipeline. When the caustic solution flows through the crystallization mesh, crystals precipitate and adhere to the crystallization mesh, thereby reducing the probability of crystallization of the caustic solution in the water seal tank and avoiding the crystallization from blocking the combustible gas outlet hole of the water seal tank.

[0027] An anti-crystallization oil-gas water seal tank device 100 is provided in an embodiment of the present utility model, which can reduce the probability of crystallization in the water seal tank.

[0028] Please refer to Figure 1 , the anti-crystallization oil-gas water seal tank device 100 provided in the embodiment of the present utility model. The anti-crystallization oil-gas water seal tank device 100 includes a water seal tank body 110. A circulation pipeline 120 is connected to the bottom of the water seal tank body 110. A circulation driving mechanism 130 is installed on the circulation pipeline 120. The circulation driving mechanism 130 can drive the lye in the water seal tank body 110 to circulate along the circulation pipeline 120. And a crystallization net 121 is installed in the circulation pipeline 120. When the lye flows through the crystallization net 121, crystals precipitate and adhere to the crystallization net 121.

[0029] During use, the circulation driving mechanism 130 drives the lye in the water seal tank body 110 to circulate along the circulation pipeline 120. When the lye flows through the crystallization net 121, crystals precipitate and adhere to the crystallization net 121, thereby reducing the probability of crystallization of the lye in the water seal tank and avoiding the combustible gas outlet holes of the water seal tank being blocked by crystals.

[0030] For the anti-crystallization oil-gas water seal tank device 100 provided in the embodiment of the present utility model, specifically, a card slot is provided in the circulation pipeline 120, and the crystallization net 121 is detachably installed in the card slot. When too much crystals adhere to the crystallization net 121, in order to avoid the crystallization net 121 affecting the flow of the lye in the circulation pipeline 120, the crystallization net 121 can be taken out of the card slot, and a brand-new crystallization net 121 can be replaced and installed in the card slot. Please refer to Figure 1 , in this embodiment, multiple layers of crystallization nets 121 are installed at intervals along the extending direction in the circulation pipeline 120. The multiple layers of crystallization nets 121 simultaneously cause the lye circulating along the circulation pipeline 120 to crystallize and precipitate, further reducing the probability of crystallization of the lye in the water seal tank.

[0031] For the anti-crystallization oil-gas water seal tank device 100 provided in the embodiment of the present utility model, further, please refer to Figure 1, a heating mechanism 140 is installed on the outer wall of the water seal tank body 110, and the heating mechanism 140 is used to heat the caustic solution in the water seal tank body 110. The heating mechanism 140 maintains the temperature of the caustic solution in the water seal tank body 110 at about 30 °C, avoiding crystallization due to the decrease in the solubility of the caustic solution under low-temperature weather conditions. When the caustic solution flows through the circulation pipeline 120, the temperature of the caustic solution decreases, resulting in a decrease in the solubility of the caustic solution and more crystallization precipitating on the crystallization mesh 121, further reducing the concentration of the caustic solution. In this embodiment, the heating mechanism 140 is an electric heating tape wrapped around the outer wall of the water seal tank body 110, and the energized electric heating tape can heat the caustic solution in the water seal tank body 110. The outside of the electric heating tape is wrapped with a heat insulation layer, and the heat insulation layer can insulate the water seal tank body 110.
