Description
Technical field
The utility model relates to emission control and the retracting device that discharging contains organic gas in the gas, be specifically related to a kind of in chemicals production, accumulating and use, the emission control of the organic gas of discharging and retracting device.
Background technology
In chemicals production, accumulating and use, often have organic gas and emit.The recovery way of organic gas commonly used mainly contains condensation method, absorption process, film separation and absorption method at present.Condensation method is by temperature that reduces gas or the pressure that increases gas, make organic gas be in hypersaturated state, the organic gas components condense is got off, this method is applicable to the recovery of higher boiling and high concentration organic gas, the organic gas concentration of component is higher in the condensed gas, can not qualified discharge.Absorption process is according to the similar principle that mixes of organic matter, the normal employing absorbent that boiling point is higher, vapour pressure is lower makes the organic gas component transfer to liquid phase from gas phase, then absorption liquid is carried out dissection process, reclaim organic component wherein, absorbent is regenerated.But the organic gas content after absorption process is handled often can not reach discharge standard.It is that to select artificial synthetic or natural membrane material for use be separating medium that film separates, the difference of infiltration rate in film according to organic gas and air, realize both separation, the motive force of transmittance process is the partial pressure difference of gas component in the film both sides, and film separates and often needs to combine the recovery that could realize organic component with other technology.Absorption method is applicable to handles the low concentration organic gas, when the organic gas concentration ratio of handling is low, can realize qualified discharge.Because intermittently, gas component the often fluctuation of concentration of the discharge process of organic gas is bigger, above-mentioned single recovery technology often can not guarantee to realize the emission control and the recovery of organic gas.
Summary of the invention
In view of existing in prior technology the problems referred to above, the utility model is intended to disclose a kind of emission control and retracting device of organic gas, and it has organic gas rate of recovery height, simple to operate, the characteristics that can realize the organic gas qualified discharge.
Technical solution of the present utility model is achieved in that
A kind of emission control of organic gas and retracting device comprise the buffering gas holder, compressor, condenser, gas-liquid separator, coalescing filter, membrane separator, absorber, the control valve that are connected in series successively by air delivering pipeline;
Described gas-liquid separator is connected with described coalescing filter in its top on-condensible gas outlet, and is connected with liquid line at the liquid outlet of its bottom;
Described membrane separator is held back side at its film and is connected with described absorber;
Described absorber comprises at least two adsorbent beds, and at least one is in adsorbed state, and one is in parse state;
Described device also comprises a vavuum pump, and described vacuum pump inlet end is connected by pipeline with the film per-meate side of described membrane separator and the parsing side of absorber respectively, and the port of export of vavuum pump then returns the inlet that is connected to compressor by air delivering pipeline.
Compared to existing technology, the utlity model has following beneficial effect:
It with condensation method, membrane separation process with absorption method organic integration be in the same place, utilize the advantage of technology separately, can effectively reclaim organic gas, and guarantee that the discharging of organic gas satisfies discharge standard; The employing of buffering gas holder then balance the fluctuation of organic gas discharging tolerance and concentration.
Description of drawings
Fig. 1 is the emission control of organic gas of embodiment and the system diagram of retracting device.
The specific embodiment
Now in conjunction with the accompanying drawings, the utility model is described in further detail:
A kind of emission control of organic gas and retracting device, as shown in Figure 1, the organic gas of from chemicals production, accumulating and use, discharging, enter into buffering gas holder 2 by air inlet pipeline 1, described buffering gas holder 2 can adopt wet type or dry type, is intended to the fluctuation of balance discharging gas tolerance and concentration.Compressor 3 gas bleeding from cushion gas cabinet 2 boosts to certain pressure then, and be sent to by air delivering pipeline and carry out condensation in the condenser 4, the gas-liquid mixture that obtains is sent to gas-liquid separator 5 to be separated, the organic liquid that obtains after the separation from gas-liquid separator 5 outlet at bottoms through liquid line 12 carrying devices; On-condensible gas from gas-liquid separator 5 top exits come out enters into coalescing filter 6, removes particle and the drop carried secretly in the air-flow, protection subsequent membrane separation device 7.In membrane separator 7, when gas process membrane module, organic gas component penetrated preferably film is in the per-meate side enrichment of film; The side of holding back at film is poor organic gas air-flow, enter by pipeline and to remove remaining organic gas in the air-flow in the absorber 8, absorber 8 has at least two adsorbent beds to form, one is in adsorbed state, another is in parse state, gas organic gas content after the absorption satisfies National Standard discharge standard of air pollutants GB 16297-1996 " discharge standard, through pressure-control valve 9 in-line arrangement tracheae lines 10 carrying devices.In order to improve the parsing effect of membrane separation efficiency and absorber 8, be provided with vavuum pump 11, the inlet of described vavuum pump 11 is connected with the per-meate side of membrane separator 7 and the parsing side of absorber 8 respectively through air delivering pipeline, the outlet of vavuum pump 11 is returned the inlet of receiving compressor 3 through air delivering pipeline, reclaims the organic gas component by further compression condensation.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
