The high-temperature steam will contain VOC gas (volatile organic compounds) that diffuses outward and pollutes the environment. Therefore, it is necessary to study a VOC control and closed device to solve the above problem. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a three-dimensional schematic diagram of the structure of the utility model;

[0013] Figure 2 is a cross-sectional view of the practical closure cover;

[0014] In the figure: adsorption tube 1, buffer cover 2, closing cover 3, cylinder 4, transverse wedge-shaped sealing strip 5, longitudinal wedge-shaped sealing strip 6, tar residue box 7, support frame 8, connecting frame 9. DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0016] like Figure 1 As shown, a VOC treatment closed device includes a tar slag box 7 with an open top, and a closed cover 3 is arranged on the top of the tar slag box 7. The closed cover 3 is lifted and lowered by lifting the adsorption component to achieve closed adsorption of waste gas. The up and down movement of the closed cover 3 can ensure the treatment of the tar slag box 7 and prevent VOC gas leakage. A rubber sealing component is arranged inside the closed cover 3.

[0017] like Figure 1 As shown, the lifting adsorption assembly includes an adsorption tube 1, a buffer cover 2 is sleeved at the lower part of the adsorption tube 1, a closing cover 3 facing the top of the tar slag box 7 is fixed at the lower part of the buffer cover 2, and both sides of the closing cover 3 are fixedly connected to both sides of the adsorption tube 1 through a lifting cylinder 4.

[0018] like Figure 2 As shown, the rubber sealing assembly includes a transverse wedge-shaped sealing strip 5 and a longitudinal wedge-shaped sealing strip 6 which are arranged on the inner wall side of the buffer cover 2 .

[0019] like Figure 2 As shown, the transverse wedge-shaped sealing strip 5 is fixed on the inner side wall of the buffer cover 2 and is inclined upward. The longitudinal wedge-shaped sealing strip 6 is arranged on the inner upper edge of the closing cover 3. The transverse wedge-shaped sealing strip 5 and the longitudinal wedge-shaped sealing strip 6 ensure close contact with the top of the tar slag box 7, and the wedge shape can also eliminate the shaking of the tar slag box 7 and prevent the gas from leaking and spreading outward.

[0020] A sliding frame is arranged inside the buffer cover 2, and a sealing sponge layer is arranged inside the sliding frame.

[0021] Connecting frames 9 connected to the piston rod of the cylinder 4 are arranged on both sides of the upper part of the buffer cover 2 .

[0022] The implementation principle of a VOC treatment and sealing device in the embodiment of the present application is as follows:

[0023] The VOC gas generated by the tar slag in the tar slag box 7 enters the adsorption tube 1 along the upper closed cover 3, and is adsorbed to the VOC treatment system through the adsorption tube 1 for treatment, so as to prevent the VOC gas from spreading outward and polluting the environment. When there is a lot of tar slag in the tar slag box 7 and it needs to be cleaned, the cylinder 4 can be operated to lift the closed cover 3 pressed on the top of the tar slag box 7, and it rises along the adsorption tube 1 through the buffer cover 2, so that the closed cover 3 is separated from the tar slag box 7;

[0024] After detachment, use a forklift to fork the tar slag box 7 on the support frame 8, and after the tar slag box 7 is forked away for transportation, the tar slag box 7 is placed under the buffer cover 2, and the cylinder 4 is operated in reverse to press the closing cover 3 to the top edge of the tar slag box 7. The horizontal and vertical sealing strips 5 and the longitudinal wedge-shaped sealing strips 6 on the inner side of the closing cover 3 are used to seal and block the VOC gas from escaping, thereby ensuring the sealing of the closing cover 3.
