Abstract
The utility model relates to a vacuum tail gas absorption device used in polystyrene production, which belongs to the technology field of tail gas treatment. A vacuum tail gas tube is introduced into a white oil groove, a white oil groove overflow gas tube is connected at the lower part of an absorption tower, a white oil spray header is arranged at the upper part of the absorption tower, and a top gas outlet tube is connected with an activated carbon absorber. The vacuum tail gas absorption device adsorbs tail gas produced in polystyrene production with white oil, resulting in above 98% of tail gas absorption rate, so that not only the tail gas emission meets requirements, but also the raw materials are recycled and reutilized. The entire process has low investment and high efficiency.
Description
Technical field
The utility model belongs to the vent gas treatment technical field, refers in particular to the absorption plant of vacuum tail gas in a kind of polystyrene production.
Background technology
Produce polystyrene resin with bulk technique, in vacuum state, carry out in the polymerization process, under vacuum action, the styrene tail gas that has trace has certain influence in vacuum terminal port volatile emission to the air of operation area, improvement to vacuum tail gas, just adopt water to absorb back emptying, be about to vacuum tail gas and directly enter in the water and discharge, water absorbs the water that produces can't be separated with cinnamic mixture, though mixture is measured less, still do not reach emission request.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, the absorption plant of vacuum tail gas in a kind of polystyrene production is provided, its disposable absorptivity reaches more than 98%, reach vacuum tail gas qualified discharge fully, the main improvement is that modify-water is absorbed as white oil and absorbs, and lays by the process equipment circulation to reach the utility model purpose.Specifically implement like this: the absorption plant of vacuum tail gas during polystyrene is produced, it is characterized in that the vacuum offgas duct feeds in the white oil groove, the white oil groove overflows tracheae and is connected the bottom, absorption tower, and top, absorption tower is equipped with the white oil spray head, and the top escape pipe connects the active carbon adsorption device.Vacuum tail gas is after the white oil groove absorbs, and a small amount of unabsorbed tail gas enters the bottom, absorption tower, once more fully contacts absorption with the white oil that sprays from top to bottom, residual air emptying after charcoal absorption again, and the absorptivity of whole process reaches more than 98%.
Be laid with connecting pipe between white oil groove and top, absorption tower spray head in the utility model, one circulating pump is installed on the connecting pipe, the white oil feed pipe is connected on the pipeline between white oil groove and circulating pump, this feed cycle design of white oil, can make and guarantee in the technology that white oil in time replenishes and changes, and improves absorptivity.
After white oil recycles a period of time, can enter in the polystyrene production technology by another discharge nozzle of circulating-pump outlet and recycle, resource is fully used.
The utility model white oil groove top is equipped with an overflow pipe, itself and absorption tower bottom discharge pipe and insert circulating pump and top, absorption tower spray head between pipeline on, but enter the absorption tower if enter too many white oil overflow in the white oil groove, the white oil that flow out the bottom, absorption tower then can be recycled, after the absorption tower white oil uses a period of time, also can enter in the polystyrene production technology and circulate by pipeline.
The utility model is equipped with the porcelain ring filler in order to increase the treatment effeciency on absorption tower in the absorption tower.
The utility model adopts white oil to absorb the vacuum tail gas of polystyrene in producing just, and the tail gas absorptivity is reached more than 98%, not only makes exhaust emissions reach requirement, and reuse recycled raw material, and whole technology investment is few, the efficient height.
Description of drawings
Accompanying drawing is a process chart of the present utility model.
The specific embodiment
The absorption plant of vacuum tail gas during polystyrene is produced, vacuum offgas duct 12 feeds in the white oil groove 1, and the white oil groove overflows tracheae 10 and is connected 2 bottoms, absorption tower, and 2 tops, absorption tower are equipped with white oil spray head 11, the porcelain ring filler is housed in the absorption tower 2, and the top escape pipe connects active carbon adsorption device 3; Be laid with connecting pipe 9 between white oil groove 1 and absorption tower 2 top spray heads, a circulating pump 4 is installed on the connecting pipe 9, white oil feed pipe 5 is connected on the pipeline of 4 of white oil groove 1 and circulating pumps; Circulating pump 4 outlets are equipped with another discharge nozzle 6 and are connected with the polystyrene production technology; White oil groove 1 top is equipped with an overflow pipe 7, itself and absorption tower 2 bottom discharge pipes 8 and insert circulating pump 4 and absorption tower 2 top spray heads between pipeline 9 on.
