Description

Technical Field

[0001] The utility model relates to the field of environmental protection VOCs treatment in the chemical industry, and particularly to a sealing device for volatile organic gases in an acid tar discharge pipe. Background Art

[0002] During the production process of the saturated ammonium sulfate section in the chemical product recovery workshop of a coke dry quenching production enterprise, odor gases and acid tar are generated in the saturator. These generated gases and liquids are collected in the overflow tank of the corresponding saturator. The acid tar impurities in the overflow tank need to be cleaned irregularly. However, the acid tar pipe is open downward, and the discharged acid tar needs to be received from this pipe opening irregularly, so it is difficult to be sealed. When discharging acid tar, volatile gases will also be discharged to the outside, causing odor leakage at the production site. Moreover, the open state increases the air volume required for the fan to treat volatile organic gases, resulting in increased power consumption and elevated economic costs. On the one hand, the collection effect is reduced, and on the other hand, the treatment volume of volatile organic gases is also increased. Summary of the Invention

[0003] The main purpose of the utility model is to provide a sealing device for volatile organic gases in an acid tar discharge pipe, aiming to solve the problems that when discharging acid tar impurities, volatile gases will also be discharged to the outside, causing odor leakage at the production site. Moreover, the open state increases the air volume for collecting volatile organic gases, resulting in increased power consumption and elevated economic costs. On the one hand, the collection effect is reduced, and on the other hand, the treatment volume of volatile organic gases is also increased.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: A sealing device for volatile organic gases in an acid tar discharge pipe, including a saturated ammonium sulfate unit, an overflow tank, a collection fan, and a steel structure column; the saturated ammonium sulfate unit includes a spraying chamber and a crystallization tank; the top of the overflow tank is provided with a top cover; the upper end of the top cover is fixedly provided with an acid tar collection pipe and a volatile gas inlet pipe; one end of the acid tar collection pipe is connected to the spraying chamber, and the other end passes through the top cover and extends into the overflow tank; an acid tar discharge pipe is provided on the upper side wall of the overflow tank; a lifting pulley is provided at the upper end of the tar discharge pipe; a sealing sleeve is sleeved outside the acid tar discharge pipe; a sealing rubber ring is provided at the bottom of the sealing sleeve.

[0005] A winch is installed at the lower part of the steel structure column, and a fixed pulley is fixedly welded at the upper part at a position parallel to the lifting pulley.

[0006] A steel wire rope is provided at the top of the sealing sleeve. The head of the steel wire rope is fixedly connected to the top of the sealing sleeve pipe, and the tail passes through the lifting pulley and the fixed pulley in sequence and is fixed on the winch.

[0009] The winch is fixedly provided with a crank.

[0010] In summary, the beneficial effects of the present utility model are as follows: The volatile gas is sealed and collected, and the gas with volatile odor is not allowed to escape to the outside. Then, the sealed volatile gas is centrally collected and uniformly treated by the collection fan. The air volume required for collecting the volatile organic gas is effectively reduced, thereby reducing the power consumption of the collection fan and the economic cost.

[0012] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings: A sealing device for volatile organic gases in an acid tar discharge pipe, comprising an ammonium sulfate saturator 1, an overflow tank 2, a collecting fan 3, and a steel structure column 4; the ammonium sulfate saturator 1 includes a spraying chamber 16 and a crystallization tank 15; the top of the overflow tank 2 is provided with a top cover; an acid tar collecting pipe 12 and a volatile gas inlet pipe 14 are fixedly arranged at the upper end of the top cover; one end of the acid tar collecting pipe 12 is connected to the crystallization tank 15, and the other end extends through the top cover into the overflow tank 2, and the acid tar generated by the ammonium sulfate saturator enters the overflow tank 2 along the acid tar collecting pipe 12; an acid tar discharge pipe 17 is arranged on the side wall at the upper end of the overflow tank 2; a lifting pulley 9 is arranged on the tar discharge pipe 17; a sealing sleeve 10 is sleeved outside the acid tar discharge pipe; a sealing rubber ring 11 is arranged at the bottom of the sealing sleeve 10. A winch 5 is installed at the lower part of the steel structure column 4, and a fixed pulley 7 is fixedly welded at a position parallel to the lifting pulley 9 at the upper part. A steel wire rope 8 is arranged at the top of the sealing sleeve, the head of the steel wire rope 8 is fixedly connected to the top of the sealing sleeve pipe 10, and the tail passes through the lifting pulley 9 and the fixed pulley 7 in sequence and is fixed on the winch 5. A sealing sleeve 10 is sleeved outside the acid tar collecting pipe 12, and the contact part between the bottom of the sealing sleeve 10 and the ground is sealed with soft rubber. On the acid tar discharge pipe 17, a lifting pulley 9 is welded at a certain height. On the adjacent steel structure column 4, a fixed pulley 7 is also welded at the same height. A winch is installed at the lower side of the steel column at a position convenient for manual operation. The steel wire rope 8 is connected to both sides of the upper edge of the sealing sleeve 10, passes through the lifting pulley 9 to the fixed pulley 7 and is led to the winch 5 for fixing, and a crank 6 is fixedly arranged on the winch 5. The lifting and lowering of the sealing sleeve 10 can be realized by manually rotating the winch 5, through the steel wire rope 8 and the pulley block. Usually, the sealing sleeve 10 device is in a state of landing, and is sealed by the soft rubber ring at the bottom ring of the sealing sleeve 10. It is in a closed state during normal times. When it is necessary to receive the acid tar in the overflow tank 2, the winch 5 is rotated manually to lift the sealing sleeve 10. After the acid tar is taken away, the sleeve is lowered to restore the closed state.
