Considering that water is commonly used as a water seal liquid, if the water quality is poor and contains impurities, pollutants and the like, it may cause problems such as precipitation and scaling in the water sealing process, block the pipeline or affect the normal operation of the water seal. For example, if the content of calcium and magnesium ions in the water is too high, scale is easily formed in the water seal device, the formation of the scale will reduce the fluidity of the water seal liquid, and affect the normal sealing effect of the water seal liquid on the tail gas. Therefore, the water seal tank body 100 is provided with a water inlet pipe 101 on the outer wall, the water inlet pipe 101 is provided with a water pump 1010 on the outer wall, an adjustable filter assembly 200 is arranged in the water inlet pipe 101, and an adjusting assembly 300 is arranged in the water inlet pipe 101.

[0021] The adjusting assembly 300 controls the movement of the filter assembly 200 to push out the impurities intercepted by the filter assembly 200, and facilitates the leakage of the filter assembly 200 from the inside of the water inlet pipe 101 to the outside for cleaning the body.

[0022] The improvement of the embodiment is that:

[0023] On the one hand, the filter assembly 200 in the water inlet pipe 101 can effectively intercept and remove impurities, organic matter and odors in the water, improve the quality of the water seal liquid, reduce the influence of impurities on the water seal device, and prolong the service life of the device. On the other hand, the design of the adjusting assembly 300 enables the filter assembly 200 to easily move from the inside of the water inlet pipe 101 to the outside, which facilitates cleaning, replacement or maintenance of the filter assembly 200, and reduces the maintenance cost and difficulty.

[0024] First, in order to pretreat the water seal liquid entering the water seal tank body 100 to remove impurities, the filter assembly 200 comprises a filter plate 201 and an adsorbed carbon plate 202, the adsorbed carbon plate 202 is arranged inside the filter plate 201, and the outer wall of the filter plate 201 is symmetrically provided with a limiting groove; the main function of the filter plate 201 is to intercept impurities in the water, prevent impurities from entering the water seal tank, affect the water seal effect or block the related pipeline; by using the adsorption characteristics of activated carbon, further remove organic matter, peculiar smell and other impurities in the water, improve the quality of the water seal liquid, and ensure the normal operation of the water seal device.

[0025] Second, in order to facilitate the position adjustment of the filter assembly 200, the adjusting assembly 300 comprises a threaded rod 301 and a limiting plate 302, the limiting plate 302 is provided with two, and is symmetrically installed on the inner wall of the water inlet pipe 101, the outer wall of the threaded rod 301 is screwed with the filter assembly 200, and the two limiting plates 302 are respectively slidably connected with the two limiting grooves. One end of each of the two limiting plates 302 is longer than the end of the water inlet pipe 101, the top ends of the two limiting plates 302 are connected with an installation plate 3020, the end of the threaded rod 301 penetrates through the installation plate 3020 and is rotatably connected with the installation plate 3020, and the top end of the threaded rod 301 is provided with a torsion block 3010; the limiting plate 302 is symmetrically installed on the inner wall of the water inlet pipe 101 and slidably connected with the limiting groove of the filter assembly 200, thereby limiting the movement range of the filter assembly 200 in the water inlet pipe 101, and ensuring that the filter assembly 200 will not deviate or shake during the working process. At the same time, when the filter assembly 200 needs to be cleaned or replaced, the limiting plate 302 can ensure that the filter assembly 200 is smoothly leaked from the inside of the water inlet pipe 101 to the outside; by rotating the threaded rod 301 through the torsion block 3010, the filter assembly 200 can be driven to move up and down in the water inlet pipe 101, so as to adjust the position of the filter assembly 200.

[0026] In addition, the tail gas discharge pipe 102 is arranged at the bottom end of the outer wall of the water seal tank body 100, which is used for connecting the normal pressure tank and the water seal device, so that the tail gas in the normal pressure tank can be smoothly introduced into the water seal tank for water seal treatment.

[0027] The utility model discloses a water seal device for atmospheric tank tail gas venting is applied in the specific use, and the operator passes through starting the water pump 1010, and the water pump 1010 extracts the external water source and is transported to the water seal tank body 100 through the inlet pipe 101.In the water inlet process, the water flow first passes through the filter assembly 200 (filter plate 201 and adsorption carbon plate 202) in the inlet pipe 101, and the filter plate 201 intercepts the larger particle impurities in the water, and the adsorption carbon plate 202 adsorbs the soluble impurities and peculiar smell in the water, and the water quality is primarily purified.After the water that is primarily purified enters the water seal tank body 100, gradually accumulates and forms a certain height of water seal layer.When the water level reaches the set height, the water pump 1010 is closed, and the stable water seal environment is formed in the water seal tank body 100.The tail gas in the atmospheric tank enters the bottom of the water seal tank body 100 through the tail gas discharge pipe 102.At this time, the water seal liquid forms liquid seal to the tail gas and prevents the leakage of the tail gas.When the tail gas passes through the water seal layer, due to the sealing and blocking effect of the water, the external air cannot enter the atmospheric tank, and the tail gas can be smoothly discharged from the discharge port of the upper portion of the water seal tank body 100.With the lapse of time, the impurities in the water can gradually accumulate on the filter plate 201, resulting in the decline of the filtering effect.At this time, the filter assembly 200 can be driven to move upwards by rotating the threaded rod 301 through the rotation of the torsion block 301.When the filter assembly 200 moves to the appropriate position, the filter assembly 200 is pushed out from the inside of the inlet pipe 101 to the outside, and the filter plate 201 is cleaned or the adsorption carbon plate 202 is replaced.After cleaning, the filter assembly 200 is reinstalled back into the inlet pipe 101, and the filtering work is continued.
