Description
Technical field
The utility model relates to a kind of viscose rayon waste gas condensation treating apparatus.
Background technology
The waste gas that produces in the viscose rayon production contains H2S and the poisonous dusty gas of CS2 stench.The waste gas that adopts alkali cleaning-adsorption condensing method to process in the viscose rayon production is the technology of comparative maturity, technical process: waste gas is through the alkali cleaning preliminary treatment, in and H2S; Waste gas behind the removal H2S enters adsorption tank, through charcoal absorption, desorption, obtains the mixed vapour of carbon disulfide and water, through after the condensation, reclaims and obtains liquid CS
2, be back to use again in the viscose rayon production.
Condensation technology is that the important process of the waste gas treatment process of alkali cleaning-adsorption condensing is processed.The carbon disulfide that reclaims in the viscose rayon exhaust-gas treatment is inflammable and explosive chemicals, and the carbon disulfide liquid that enters the carbon disulfide storage tank after the viscose rayon emission-control equipment requires to reclaim must be below the temperature of technological requirement, guarantee safety; The condensed waste gas of carbon disulfide mixed vapour will come back to adsorption tank in addition, carry out charcoal absorption, if condensation effect is poor, the carbon disulfide amount that repeats to adsorb will increase, and cause recovering effect to descend, and every energy operation unit consumption increases; After the condensation therefore the quality of condensation effect not only directly have influence on the operational effect of a whole set of viscose rayon emission-control equipment, and can cause serious potential safety hazard.Original viscose rayon exhaust gas treatment technology is designed to three grades of coolings, and third level condenser is installed before the carbon disulfide storage tank, carries out degree of depth cooling for utilizing chilled water before entering the carbon disulfide storage tank, reaches technological requirement.If the condensation of original viscose rayon emission-control equipment design exists third level condensation effect not good, it is higher that carbon disulfide enters the storage tank temperature, has potential safety hazard, and investment is also corresponding with operation energy consumption slightly increases.
Summary of the invention
The purpose of this utility model is to overcome the weak point that technique is reclaimed in original viscose rayon exhaust-gas treatment condensation, provide under a kind of prerequisite guaranteeing viscose rayon exhaust-gas treatment condensation effect, improve the security that condensation process is processed, reduce the method for equipment investment and operation energy consumption.By increasing the refrigerating capacity of condenser and gaseous effluent, cancellation is installed in the front third level condenser of carbon disulfide storage tank, only through B-grade condensation, just temperature is condensed to technological requirement before specific gravity separator, and is more safe and reliable.Through stable operation, satisfy technological requirement, cost of investment and operation energy consumption all decrease.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of viscose rayon waste gas condensation treating apparatus, it is characterized in that being provided with condenser, gaseous effluent, safety can, specific gravity separator, carbon disulfide storage tank, condenser inlet connects exhaust pipe, condensator outlet is communicated with the gaseous effluent entrance, the gaseous effluent outlet is communicated with the entrance of safety can, specific gravity separator respectively, the safety can outlet is communicated with the charcoal absorption chamber, and the specific gravity separator outlet is communicated with the carbon disulfide storage tank.
Condenser described in the utility model, gaseous effluent all adopt shell and tube condenser, and shell and tube condenser has cylindrical housings, the parallel pipe subgroup is housed in the shell and tube condenser becomes tube bank.
Condenser described in the utility model is two condensers in parallel.
The utility model after with viscose rayon emission-control equipment active carbon desorption carbon disulfide and the mixed vapour of water introduce condenser in parallel through piping, converge the condensed gas-liquid mixture of one-level, enter gaseous effluent and carry out B-grade condensation, reach the technological requirement temperature that enters the carbon disulfide storage tank, enter the carbon disulfide storage tank after separating through proportion again and store.
The utility model is simple for structure, and condensation process is effective, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment condenser.
The specific embodiment
Referring to Fig. 1, present embodiment viscose rayon waste gas condensation treating apparatus is mainly by condenser 1, gaseous effluent 2, safety can 5, specific gravity separator 3, carbon disulfide storage tank 4 forms (except the cooling tower of the auxiliary configuration of routine, infusion pump, flowmeter, butterfly valve and pipeline thereof are outer), the entrance of condenser 1 connects exhaust pipe, the outlet of condenser 1 is communicated with gaseous effluent 2 entrances, the outlet of gaseous effluent 2 and safety can 5, the entrance of specific gravity separator 3 is communicated with, the outlet of safety can 5 is communicated with charcoal absorption chamber 6, the outlet of specific gravity separator 3 is communicated with carbon disulfide storage tank 4, and each device is by pipeline connection (connection).Introduced the condenser 1 of two parallel connections in the viscose rayon emission-control equipment by pipeline through the waste gas (mixed vapour of carbon disulfide and water) behind the active carbon desorption, after advancing first-stage condenser 1 condensation, enter by the road 2 condensations of secondary gaseous effluent, reach the temperature that enters carbon disulfide storage tank technological requirement, after the liquid that produces behind the B-grade condensation separates through specific gravity separator 3, introduce carbon disulfide storage tank 4 by pipeline, waste gas behind the B-grade condensation also contains a small amount of uncooled carbon disulfide, reenters charcoal absorption chamber 6 through safety can 5 and processes.Present embodiment can dispose conventional cooling tower, infusion pump, flowmeter, butterfly valve and pipeline thereof according to actual needs, through realizing viscose rayon exhaust-gas treatment condensation recovery carbon disulfide technique after the utility model condensation process, all parts all can adopt existing techniques in realizing.Design of the present utility model is under the prerequisite that guarantees production safety, reach technological requirement, through B-grade condensation is as much as possible gaseous state carbon disulfide is condensed into liquid carbon disulphide, reduces the carbon disulfide amount that second adsorption reclaims, enhance productivity and also reduced the production unit consumption.
Referring to Fig. 2, condenser 1 and gaseous effluent 2 that the utility model embodiment adopts are shell and tube condenser, have columniform shell, in a lot of parallel pipe subgroups be housed become tube bank, make the solvent vapo(u)r condensation by heat exchange.In the utility model, what need condensation is the mixed vapour of carbon disulfide and water; Condensate liquid is cooling water (filtered water) or chilled water.
More than be the implementation under the technical solutions of the utility model framework, simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
