Description
Technical field
The utility model relates to a kind of device for recovering tail gas, the benzaldehyde product device for recovering tail gas that especially a kind of tail gas that is widely used in coking, chemical industry generation reclaims.
Background technology
In coke-oven plant's benzene refining production link, because the depositing pressure etc. and can produce tail gas of benzaldehyde product media flow, gas, while normally producing, the process units such as part storage tank also can be discharged some tail gas.There is the inflammable and explosive easy poisoning harm that waits in benzaldehyde product tail gas, and atmospheric environment is caused to more serious pollution, easily burns, the problem such as blast.In production, safety and environment protection is eternal theme, and the two is all the problem that worker is concerned about the most, has direct relation with worker's personal safety, physical and mental health.How processing these tail gas, is the problem that current chemical industry need to solve.
At present, the solution also not had.
Utility model content
Technical assignment of the present utility model is to provide a kind of benzaldehyde product device for recovering tail gas for above-mentioned deficiency of the prior art, this a kind of benzaldehyde product device for recovering tail gas has the Venturi tube of utilization and produces suction, adopt absorption process to reclaim tail gas, eliminated the pollution of benzene gas to atmospheric, guarantee safety in production, improved again the feature of the yield of benzaldehyde product.
The utility model solves the technical scheme that its technical problem adopts: it comprises Venturi tube, circulation liquid bath, recycle liquid pump, scrubbing tower and condenser, described Venturi tube is arranged on the top of circulation liquid bath, train loading tail gas, benzene groove tail gas and automobile loading tail gas enter Venturi tube by pipeline respectively, described recycle liquid pump one end is connected with circulation liquid bath by pipeline, the other end is connected with scrubbing tower with Venturi tube respectively, the bottom of described circulation liquid bath is connected with condenser, and the top of described circulation liquid bath is provided with circulation fluid tube connector.
On described recycle liquid pump and the pipeline between Venturi tube, be provided with steam inlet tube, on described steam inlet tube, be provided with steam valve.
Between described circulation liquid bath and condenser, be provided with condensation valve.
Compared to the prior art a kind of benzaldehyde product device for recovering tail gas of the present utility model, has following outstanding beneficial effect: the product loss and the economic loss that have thoroughly solved the volatilization generation of benzaldehyde product; Better solve safety guarantee, avoided the danger of breaking out of fire and blast; Have small investment, operating cost is low, instant effect, advantage free from environmental pollution; Effectively solved problem of environmental pollution, worker is healthy to be guaranteed.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of benzaldehyde product device for recovering tail gas structural representation;
Description of reference numerals: 1, Venturi tube, 2, circulation liquid bath, 3, recycle liquid pump, 4, scrubbing tower, 5, condenser, 6, pipeline, 7, circulation fluid tube connector, 8, steam inlet tube, 9, steam valve, 10, condensation valve.
The specific embodiment
With reference to 1 pair of a kind of benzaldehyde product device for recovering tail gas of the present utility model of Figure of description, be described in detail below.
A kind of benzaldehyde product device for recovering tail gas of the present utility model: it comprises Venturi tube 1, circulation liquid bath 2, recycle liquid pump 3, scrubbing tower 4 and condenser 5, described Venturi tube 1 is arranged on the top of circulation liquid bath 2, train loading tail gas, benzene groove tail gas and automobile loading tail gas enter Venturi tube 1 by pipeline 6 respectively, described recycle liquid pump 3 one end are connected with circulation liquid bath 2 by pipeline 6, the other end is connected with scrubbing tower 4 with Venturi tube 1 respectively, the bottom of described circulation liquid bath 2 is connected with condenser 5, and the top of described circulation liquid bath 2 is provided with circulation fluid tube connector 7.
On described recycle liquid pump 3 and the pipeline between Venturi tube 1, be provided with steam inlet tube 8, on described steam inlet tube 8, be provided with steam valve 9.
Between described circulation liquid bath 2 and condenser 5, be provided with condensation valve 10.
During work: train loading tail gas, the suction that benzene groove tail gas and automobile loading tail gas produce through Venturi tube 1 enters Venturi tube 1, recycle liquid pump 3 is evacuated to circulation fluid Venturi tube 1 from circulation liquid bath 2 simultaneously, the tail gas entering in Venturi tube 1 is contacted to washing, then circulation fluid and the tail gas after washing enters circulation liquid bath 2, enter from the bottom to top again scrubbing tower 4, in uphill process, draw up with recycle liquid pump 3 circulation fluid coming and contact washing, benzaldehyde product in tail gas is recycled liquid and absorbs, tail gas after cleaning is discharged along scrubbing tower 4 tops, when circulation fluid is greater than 2% containing benzene, this circulation fluid is sent to the de-benzene of debenzolizing tower between recovery vehicle, in order to reduce washing oil temperature, the circulation fluid in circulation liquid bath 2 is cooling by condenser 5, makes circulation fluid temperature remain 25-30 ℃, and described circulation fluid is washing oil.
When tail gas recycle pipeline complete or that be connected with recycle liquid pump 3 freezes, by passing into steam 8 on the pipeline being connected with recycle liquid pump 3, pipeline is heated, remove circulation fluid residual on pipeline or pipeline is thawed.
Benzaldehyde product device for recovering tail gas of the present utility model adopts suction that Venturi tube 1 produces as tail gas collecting, clean power, and tail gas sprays through wash cycle liquid that to enter Venturi tube 1 be to clean for the first time, outer row after scrubbing tower is cleaned for 4 two times.This technological merit collection Venturi tube 1, scrubbing tower 4, circulation liquid bath 2 Trinity, floor space is little, invest little, convenient operation.
Utilize the self-produced washing oil in tar workshop, coke-oven plant as wash cycle liquid, tail gas to be reclaimed, without the independent raw material of buying, and recycle in the wash cycle Ye Ke factory after washing, there is no loss, save processing cost.This method is applicable to the recovery process of benzaldehyde product tail gas, has good environmental benefit, economic benefit and social benefit.
Except the technical characterictic described in description, be the known technology of those skilled in the art.
