Abstract
The utility model relates to an isobutylene tail gas recycling device, and belongs to the field of chemical equipment. The isobutylene tail gas recycling device comprises a return tank and a heating coal furnace, the return tank is connected with a condenser through a pipeline, the condenser is respectively connected with a buffer tank and a heating coal furnace through the pipeline, the buffer tank is respectively connected with the heating coal furnace and a recycling device through the pipeline. The vast majority of isobutylene product and heave components can be recycled through the isobutylene tail gas recycling device, the economic benefit is high, the smoke emission is reduced, and the device is energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of isobutene device for recovering tail gas, belongs to chemical industry equipment field.
Background technology
Isobutene is a kind of important Organic Chemicals that is widely used in medicine, agricultural chemicals, antioxidant, synthetic senior lubricant and other fine chemical products.Wherein highly purified isobutene can be used for producing butyl rubber and polyisobutene, and butyl rubber is mainly used to produce tire and Medical bottle stopper.Isobutene has toxicity, to water body, soil and atmosphere, can pollute, therefore, containing must process processing before the exhaust emissions of isobutene.Processing mode was burnt for the tail gas containing isobutene directly enters pipestill for heat carrier in the past, this mode is burnt nearly 70% the isobutene composition containing in tail gas on the one hand in vain, economic benefit is low, exhaust smoke level is large, existence due to moisture in tail gas can cause isobutene burning insufficient to environment on the other hand, and it is quick-fried that sudden strain of a muscle easily occurs during burning, has potential safety hazard.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of isobutene device for recovering tail gas is provided, and recyclable most isobutenes, economic benefit is high, reduces fume emission, energy-conserving and environment-protective.
Isobutene device for recovering tail gas described in the utility model, comprises return tank, pipestill for heat carrier, and return tank connects condenser by pipeline, and condenser connects respectively surge tank, pipestill for heat carrier by pipeline, and surge tank connects respectively pipestill for heat carrier, retracting device by pipeline.
By condenser is set, water vapour in tail gas can be cooled to liquid state, the heavy constituents such as the isobutene in tail gas and aqueous water enter surge tank by condenser below by pipeline, enter tail gas AUTOMATIC ZONING under Action of Gravity Field of surge tank, heavy constituent, water and most isobutene enter retracting device by surge tank bottom, the recovery of heavy constituent and isobutene has improved economic benefit, and reduced the pipestill for heat carrier tail gas amount that enters, reduce fume emission, reduce environmental pollution, tail gas is abundant through dehydration after-combustion, eliminates safe hidden trouble.
Described return tank connects pipestill for heat carrier by pipeline.
On described pipeline, by-pass valve control is set, can realizes the flow direction of tail gas and control.When needs overhaul condenser or surge tank, can closing volume tank and condenser between valve, open the valve between pipestill for heat carrier and return tank, do not affect exhaust emissions, guarantee continuous production, after maintenance, switch back again.
Containing isobutene tail gas, by return tank, enter condenser, steam is cooled to liquid state through condenser, aqueous water, isobutene and heavy constituent are entered surge tank and are entered by the road retracting device by pipeline, part light component enters pipestill for heat carrier burning, enter tail gas in surge tank after Action of Gravity Field lower leaf, heavy constituent enters retracting device, and light component enters pipestill for heat carrier and burns.
The beneficial effect that the utility model compared with prior art had is:
The recyclable most isobutene products of this isobutene device for recovering tail gas and heavy constituent, economic benefit is high, reduces fume emission, energy-conserving and environment-protective; By removing the moisture content in tail gas, make exhaust combustion more abundant, eliminate safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, return tank; 2, by-pass valve control; 3, pipestill for heat carrier; 4, condenser; 5, surge tank; 6, retracting device.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As Fig. 1, the present embodiment comprises return tank 1, return tank 1 top connects respectively condenser 4, pipestill for heat carrier 3 by pipeline, condenser 4 upper pipelines connect pipestill for heat carrier 3, condenser 4 bottoms connect surge tank 5 tops by pipeline, surge tank 5 tops connect pipestill for heat carrier 3 by pipeline, and surge tank 5 bottoms connect retracting device 6 by pipeline, and by-pass valve control 2 is set on all pipelines
Containing isobutene tail gas, by return tank 1, enter condenser 4, steam in tail gas is cooled to liquid state through condenser 4, aqueous water, isobutene and heavy constituent enter surge tank 5 by pipeline, part light component enters pipestill for heat carrier 3 and burns, enter tail gas in surge tank 5 in Action of Gravity Field lower leaf, heavy constituent, aqueous water and isobutene enter retracting device 6 by below pipeline, and light component enters pipestill for heat carrier 3 and burns.When needs overhaul surge tank 5 and condenser 4, by-pass valve control 2 between closing volume tank 1 and condenser 4, opens the by-pass valve control 2 between return tank 1 and pipestill for heat carrier 3, enters pipestill for heat carrier 3 and burn between tail gas, after maintenance, then by-pass valve control 2 is switched back to normal condition.
