Abstract
The utility model relates to a waste gas recovery device and belongs to the field of environmental-friendly equipment. The waste gas recovery device is provided with an absorbing tank and is characterized in that a gas inlet of the absorbing tank is communicated with a gas outlet of a buffer tank, a gas outlet of the absorbing tank is connected with a gas inlet of a tubular condenser, a gas outlet of the tubular condenser is connected with an extraction opening of a vacuum unit, and liquid outlets of the tubular condenser, the absorbing tank and the buffer tank are connected with a liquid inlet of a recovery tank. According to the waste gas recovery device, the structure is simple, the emission requirement can be flexibly and controllably met, the energy resource is saved, and the cost is also reduced.
Description
Technical field
The utility model relates to the environmental protection equipment field, at length says it is a kind of waste gas recovering device.
Background technology
As everyone knows, in the carbon fiber production process, emission-control equipment is the polymer fluid deaeration, take off the process of list, discharging waste gas, recycling.The bubble that contains monomer residual in monomer (acrylonitrile) unreacted about 4%, the polymer fluid and generation in the polymer fluid needs just contain monomer (acrylonitrile) like this in the exhaust gas discharged through vacuum removal, and directly discharging wastes and contaminated environment.Most methods such as burning, plasma, charcoal absorption that adopt are handled, and can not recycle and increase power consumption.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of waste gas recovering device, and is simple in structure, can satisfy to flexible and controllable emission request, saves the energy again and reduces cost.
The utility model solves the technical scheme that its technical problem adopted: a kind of waste gas recovering device; Be provided with tourie; It is characterized in that the air inlet of tourie is connected with the gas outlet of surge tank, the gas outlet of tourie links to each other with the air inlet of shell and tube condenser; The gas outlet of shell and tube condenser links to each other with the bleeding point of vacuum unit, and the liquid outlet of shell and tube condenser, tourie and surge tank is connected with the inlet of recycling can.
The beneficial effect of the utility model is, and is simple in structure, can satisfy to flexible and controllable emission request, saves the energy again and reduces cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model, also is the sketch map of a kind of embodiment.
Fig. 2 is the sketch map of another embodiment of the utility model.
1. surge tanks among Fig. 1,2. tourie, 3. shell and tube condenser, 4. recycling can, 5. vacuum unit.
The specific embodiment
Embodiment one:
In Fig. 1; The utility model is provided with tourie 2; The air inlet of tourie 2 is connected with the gas outlet of surge tank 1; The gas outlet of tourie 2 links to each other with the air inlet of shell and tube condenser 3, and the gas outlet of shell and tube condenser 3 links to each other with the bleeding point of vacuum unit 5, and the liquid outlet of shell and tube condenser 3, tourie 2 and surge tank 1 is connected with the inlet of recycling can 4.
Embodiment two:
In Fig. 2; This embodiment uses the two-stage tourie; The air inlet of tourie 2 is connected with the gas outlet of surge tank 1, and the gas outlet of tourie 2 links to each other with the air inlet of another tourie, and the gas outlet of another tourie links to each other with the air inlet of shell and tube condenser 3; The gas outlet of shell and tube condenser 3 links to each other with the bleeding point of vacuum unit 5, and the liquid outlet of shell and tube condenser 3, tourie 2, another tourie and surge tank 1 is connected with the inlet of recycling can 4.
The utility model dissolves the monomer in the waste gas (acrylonitrile) through the alembroth in the tourie (dimethyl sulfoxide (DMSO)); Condenser carries out the degree of depth (being lower than 7 ℃) condensation to the solvent of micro-waste gas monomer and volatilization; Vavuum pump is accomplished air-breathing, the exhaust of waste gas; When surge tank prevented that system vacuum from breaking down, the absorption liquid suck-back got into the polymer fluid bubbling system; Absorption liquid is put into recycling can, gets into paradigmatic system again after the analytical concentration allotment.One or more tourie of arranged in series and a condenser guarantee to reclaim fully qualified discharge.
