Abstract
The utility model relates to an emission reduction device of volatile solvent. The utility model discloses simple structure, convenient to use can effectively reduce harmful gas and discharge, and the security is good. The emission reduction device for the volatile solvent comprises a flexible gas cabinet, a U-shaped liquid seal pipe and an exhaust pipe, wherein the U-shaped liquid seal pipe and the flexible gas cabinet are connected to one end of the exhaust pipe in parallel, and the other end of the exhaust pipe is connected with a storage tank of the volatile solvent.
Description
Technical Field
The utility model relates to an emission reduction device of volatile solvent.
Background
The solvent storage tank or storage tank belongs to a normal pressure container, if the solvent has strong volatility, a breather valve is generally arranged on an exhaust pipe to reduce the emission, but in practical application, due effect cannot be achieved, and the direct discharge is equal to direct discharge when one positive pressure valve and one negative pressure valve in the breather valve are not closed tightly. Because of the amount of solvent added to the sealed container, the same volume of gas needs to be evacuated, at the same rate as the solvent is added. Similarly, the same volume of air must be admitted to the tank to ensure pressure equalization as much solvent is withdrawn therefrom. The emission of solvent gas can cause waste, and if the gas is ether, ethanol and the like which are inflammable or has certain gas harm, the atmosphere is polluted, and great safety can be caused to cause hidden troubles.
Disclosure of Invention
To the problem, the utility model provides a volatile solvent's emission reduction device, its simple structure, convenient to use can effectively reduce harmful gas and discharge, and the security is good.
In order to achieve the purpose, the utility model adopts the technical proposal that: the emission reduction device for the volatile solvent comprises a flexible gas holder, a U-shaped liquid seal pipe and an exhaust pipe, wherein the U-shaped liquid seal pipe and the flexible gas holder are connected to one end of the exhaust pipe in parallel, and the other end of the exhaust pipe is connected with a storage tank for the volatile solvent.
Preferably, an evaporator connected with a cooling machine is arranged in the flexible gas holder, and a solvent discharge pipe is arranged at the bottom of the flexible gas holder; an air pressure switch/electric contact pressure gauge is arranged on an exhaust pipe between the flexible gas cabinet and the U-shaped liquid seal pipe, and the air pressure switch/electric contact pressure gauge is electrically connected with the cold motor; when the set pressure is exceeded, the cooling machine is started, and the cooling machine stops working when the set pressure is lower than the set pressure.
Preferably, the rear end of the U-shaped liquid seal pipe is connected with an emptying pipe, and a seal liquid recovery tank is arranged below an outlet of the emptying pipe; the sealing liquid can be recycled, when the sealing liquid which is mutually soluble with the volatile solvent is adopted, the sealing liquid can be further processed, and the solvent is recycled through the sealing liquid.
Beneficial effects of the utility model
The utility model discloses a U type liquid seal pipe replaces the breather valve, can reduce the harmful gas and discharge, simple structure, and U type liquid seal pipe is except playing the gaseous effect of liquid seal, simultaneously takes the role such as positive and negative barometer, relief valve concurrently, and does not need the check-up, and sustainable use, convenient and reliable, solvent gas in the storage tank is completely isolated through the liquid seal with the atmosphere, and the security is good. The flexible gas holder is additionally arranged on the exhaust pipe, and the ordered flow of volatile medium gas is completed by utilizing atmospheric pressure so as to realize the effect of balancing pressure difference.

Detailed Description
The emission reduction device for the volatile solvent comprises an exhaust pipe 1, a flexible gas cabinet 3, an air pressure switch 6, a U-shaped liquid seal pipe 10, an evaporator 4 and a cold engine 11, wherein the front end of the exhaust pipe 1 is connected with a storage tank 2 of the volatile solvent, the rear end of the exhaust pipe is respectively connected with the flexible gas cabinet 3 and the U-shaped liquid seal pipe 10 in parallel, the air pressure switch 6 is installed on the exhaust pipe 1 between the flexible gas cabinet 3 and the storage tank 2 and is electrically connected with the cold engine 11, when the set pressure is exceeded, the cold engine 11 is started, and otherwise, the cold engine 11 stops working. The evaporator 4 is arranged in the flexible gas holder 3 and is connected with a cold engine 11 arranged outside the flexible gas holder 3, the rear end of the U-shaped liquid seal pipe 10 is connected with an emptying pipe 8, and a seal liquid recovery tank 9 is arranged below the outlet of the emptying pipe 8. The air pressure switch 6 can be replaced by an electric contact pressure gauge, and the cold motor 11 can also be replaced by an existing air conditioner external unit, so that investment is saved.
Before the sealing device is used, the front end of the exhaust pipe 1 is connected with the top of a storage tank 2 of a volatile solvent, sealing liquid components and the using amount of the sealing liquid are selected according to the type and the volatility of the solvent, and sealing liquid is injected into the U-shaped liquid sealing pipe 10. The upper and lower limit pressures of the air pressure switch 6 are set. When adding solvent into storage tank 2, because storage tank 2 volume is balanced and decided, the solvent gas who discharges from storage tank 2 receives atmospheric pressure and the influence of U type liquid seal pipe liquid difference, can get into flexible gas holder 3 through blast pipe 1, the volume of flexible gas holder 3 increases thereupon, if atmospheric pressure in blast pipe 1 surpasss atmospheric pressure switch 6 and sets for the high-pressure value, chiller 11 starts, cool off the solvent gas in the flexible gas holder 3 through evaporimeter 4, the solvent that obtains discharges through solvent discharge pipe 5 that sets up in flexible gas holder 3 bottom, return the storage tank or carry the production line and put into use. When the solvent is extracted from the storage tank 2, the pressure in the storage tank 2 is reduced, and the flexible gas holder 3 returns the gas in the storage tank 2 from the exhaust pipe 1 to the storage tank 2 under the action of the atmospheric pressure, so that the balance of the pressure in the storage tank 2 is maintained, and the automatic adjustment is realized.
