Detailed description of the invention
nullSee Fig. 1，A kind of Wind Volume Carbon bisulfide emission-control equipment of this utility model embodiment，Including chemical washing blower fan 1、Chemical scrubber 2、Water scrubber 3、Spray separator 4、Dirty gas blower fan 5、Adsorption tank 6(totally 8，Numbered: adsorption tank A、Adsorption tank B、Adsorption tank C、Adsorption tank D、Adsorption tank E、Adsorption tank F、Adsorption tank G、Adsorption tank H)、Vaporizer 7、Condenser 8、Gaseous effluent 9、Safety can 10、Specific gravity separator 11、Tail condenser 12、Carbon bisulfide storage tank 13，Chemical washing blower fan 1、Chemical scrubber 2、Water scrubber 3、Spray separator 4、Dirty gas blower fan 5、Adsorption tank 6、Vaporizer 7、Condenser 8、Gaseous effluent 9、Safety can 10 is sequentially communicated，Condenser 8、Gaseous effluent 9、Safety can 10 is respectively provided with liquid outlet，Condenser 8、Gaseous effluent 9、The liquid outlet of safety can 10 is all connected with specific gravity separator 11，The gas outlet of safety can 10 connects with adsorption tank 6 entrance，Specific gravity separator 11、Tail condenser 12、Carbon bisulfide storage tank 13 is sequentially connected with.
Waste gas is blown into chemical scrubber 2 by chemical washing blower fan 1 by emission-control equipment, other gas componants removed in waste gas in addition to Carbon bisulfide by certain density chemical solution in chemical scrubber 2, avoiding these gas componants that the adsorbent in adsorption tank is produced impact, after general requirement processes, other gas componants (such as: hydrogen sulfide) are less than 5ppm.Waste gas, by entering water scrubber 3 after chemical scrubber 2, is lowered the temperature by waste gas by recirculated water, and cooling extent is about 10 degrees Celsius.Waste gas after water scrubber 3 is lowered the temperature is by spraying separator 4, the moisture being eliminated as much as in waste gas, excess moisture is avoided to affect the adsorbent adsorption efficiency to Carbon bisulfide after entering adsorption tank, through dirty gas blower fan 5, Carbon bisulfide waste gas is blown into adsorption tank 6 again, adsorption tank 6 utilizes the adsorbent of internal filling to adsorb Carbon bisulfide, adsorption tank 6 quantity is 8, and wherein 6 adsorption tanks normally use, and remaining 2 adsorption tank is as standby or carry out PROCESS FOR TREATMENT.Adsorb saturated after, the normal adsorption tank used is desorbed in turn, the method such as steam or vacuum is utilized to be desorbed out by Carbon bisulfide, desorption carbon disulfide gas out is through vaporizer 7, by condenser 8, gaseous effluent 9, carbon disulfide gas being cooled to liquid again, a little carbon disulfide gas not being condensed is again introduced into adsorption tank 6 after safety can 10 and adsorbs.Condensed liquid carbon disulphide enters specific gravity separator 11, and specific gravity separator 11 carries out Carbon bisulfide and separates with water, and the Carbon bisulfide liquid after separating is sent into Carbon bisulfide storage tank 13 after tail condenser 12 is cooled to technological requirement temperature and stored.
After adsorption tank 6 adsorbs a period of time Carbon bisulfide waste gas, adsorbent ability declines, and needs to carry out corresponding PROCESS FOR TREATMENT, and the time of PROCESS FOR TREATMENT more saves, then be more beneficial to the absorption of Carbon bisulfide.General PROCESS FOR TREATMENT is divided into carrying out washing treatment and drying and processing, carrying out washing treatment typically uses soft water or certain density chemical solution to wash adsorbent, time is generally 2 days, drying and processing is carried out again after carrying out washing treatment, adsorbent is dried cooling, then completing the PROCESS FOR TREATMENT of this adsorption tank, the drying and processing time is generally 1 day.Existing enterprise puts into build and processes Carbon bisulfide waste gas 120000 cubes～the waste gas recovering device of 130000 cubes per hour, design adsorption tank is 6, wherein 1 adsorption tank is standby or carries out PROCESS FOR TREATMENT, first carry out carrying out washing treatment when adsorption tank carries out PROCESS FOR TREATMENT and carry out drying and processing again, then first adsorption tank starts PROCESS FOR TREATMENT for the first time to time of PROCESS FOR TREATMENT next time is 18 days.This adsorption tank device diameters is 5.6～5.8 meters, and after device puts into operation, tail gas exceeds standard seriously, reaches as high as more than 2000ppm.
In this Carbon bisulfide emission-control equipment, adsorption tank quantity is 8, wherein 6 adsorption tanks normally use, remaining 2 adsorption tank is as standby or carry out PROCESS FOR TREATMENT, when carrying out PROCESS FOR TREATMENT, 2 adsorption tanks are staggered simultaneously carries out carrying out washing treatment and drying and processing, PROCESS FOR TREATMENT is prior art, processing sequence is with reference to Fig. 2, then first adsorption tank starts PROCESS FOR TREATMENT for the first time to time of PROCESS FOR TREATMENT next time is 16 days, PROCESS FOR TREATMENT circulation time shortens, and is beneficial to raising and the reduction of tail gas concentration of this Carbon bisulfide emission-control equipment adsorption efficiency.
In this Carbon bisulfide emission-control equipment, adsorption tank device diameters is less than 5 meters, and device bottom is designed with air uniform plate structure.Adsorption tank uses bottom inflow, and the design of top vent, the distribution in adsorption tank of the adsorption tank size the biggest then waste gas is the most uneven, is more unfavorable for the adsorbent Carbon bisulfide of surrounding, the situation that tail gas exceeds standard easily occurs.This device adsorption tank device diameters is less than 5 meters, then designs air uniform plate structure, the adsorption tank compared to a diameter of 5.6～5.8 meters, being more evenly distributed in Carbon bisulfide waste gas adsorption tank again in device bottom, and adsorption efficiency is high, and tail gas concentration has and reduces largely.
Wind Volume Carbon bisulfide emission-control equipment described in the utility model is reasonable in design, and adsorption efficiency is high, and process treatment time is short, and tail gas concentration is low
More than it is being embodied as under technical solutions of the utility model framework, every this utility model embodiment technical scheme and the simple deformation of technical characteristic or combination, is all deemed to fall protection domain of the present utility model.
