A kind of tail gas recycling and treating device of Chinese medical extract
Technical field
The utility model relates to a kind of tail gas recycling and treating device, particularly a kind of tail gas recycling and treating device of Chinese medical extract.
Background technology
Less in the market seeing about the Chinese medicine device for recovering tail gas, in the traditional Chinese medicine extraction process, usually be directly the tail gas that produces to be entered in the atmosphere, the solvent that contains some on the one hand in the tail gas, if directly discharging will be lost the solvent of 2.5-4.5kg/ ton, environment has not only been polluted in the discharging of tail gas on the other hand, and also grievous injury people's health of many noxious materials wherein.
Summary of the invention
The purpose of this utility model is the problem that is occurred in the present tail gas recycle, provides a kind of simple in structure, easy to operate, and effect is remarkable, tail gas can be converted into the retracting device of liquid state organics.
The purpose of this utility model is achieved in that it comprises cover (1) and tank body (11) two parts, and its technical scheme is: cover (1) is a cavity, and the centre separates with dividing plate (2); There is a tail gas inlet pipeline (9) upper end of cover (1), and there is a tail gas outlet conduit (3) lower end; The jar core (6) of tank body (11) is a solid cylindrical shell that has a plurality of U-shaped pipelines (7), and coupling flange (4) has aperture in the position corresponding with U-shaped pipeline (7) mouth of pipe; There is passageway (10) inside at jar core (6) periphery and tank body (11) shell; Tank body (11) has a cooling water inlet pipeline (5) in the lower end near cover (1) one side, and coolant outlet pipeline (8) is arranged at the top of tank body (11) opposite side.
Described cover (1) is fixedlyed connected by coupling flange (4) with tank body (11).
Described U-shaped pipe (7) is positioned at the neighboring of a jar core (6).
Beneficial effect of the present utility model is: reduced the discharge capacity of tail gas, the tail gas of gaseous state is converted into liquid tail gas, reduced the processing cost of tail gas, recovered solvent can increase the economic benefit of a part simultaneously.
