Abstract
The utility model relates to a soda production device, in particular to a soda production device capable of recycling waste gas of a calciner. The soda production device solves the direct dischargingproblem of CO2 waste gas in the prior soda production device. The soda production device comprises a carbonization tower, a thickener, a soda filter, a calciner, a condensing tower and a scrubbing tower connected in sequence, wherein the scrubbing tower is connected with a water separator; the water separator is connected with a compressor; the compressor is connected with a rear carbonization tower; and the discharge port of the rear carbonization tower is connected with the thickener. The soda production device can recycle the waste gas of the calciner, and has the advantages of simple process, short process flow, reduced emission of greenhouse gas CO2, improved production efficiency and output, and good production benefit and environment benefit.
Description
Technical field
The utility model relates to a kind of soda ash production equipment, is specially a kind of production soda ash device that the calcining tail gas recycle can be utilized again.
Background technology
Over past ten years, what attract people's attention most in the great number of issues of global environment is the problem that the earth warms gradually, i.e. Greenhouse effect.The major cause of generation Greenhouse effect is exactly a large amount of dischargings of carbonic acid gas, and feasible sea level rise, living species becomes extinct, farm output descends, biology moves on a large scale etc., so how to control CO
2Discharging caused worldwide extensive concern.The general process of soda ash manufacturing is, ammoniated brine is sent into system washing tower (for removing CO2) top by pump through interchanger, and the compressed gas counter current contact of sending here with compressor is carried out carburizing reagent and absorbed CO
2, produce NaHCO
3Crystallization is from making the NaHCO that washing tower (for removing CO2) comes out
3Slurries are by going into carbonization stiff device from baric flow, again through obtaining heavy alkali behind the vacuum filter, after calcining, make soda ash, in calcination process, can produce a large amount of carbon dioxide tail gas, these titanium dioxide gases generally are to be discharged in the air, not only cause energy dissipation but also have quickened the climate warming effect.
Summary of the invention
The utility model provides a kind of production soda ash device that tail gas recycle is utilized again of calcining for the problem that solves the direct discharging of CO 2 waste gas that produces in the existing soda ash production technology.
The utility model is realized by following technical scheme, a kind ofly calcine the production soda ash device that tail gas recycle is utilized again, comprise the carbonating tower, stiff device, Alkali-filter, calcining furnace, condensing tower, the washing tower that connect successively, behind washing carbon, be connected with water separator, be connected with compressor behind the water separator, compressor is connected with the back carbonating tower, and the discharge port of back carbonating tower is tieback stiff device again.
Compared with prior art, the utility model has increased by a cover calcining exhaust collection filtration unit and has added a carbonating tower in addition at the end of the device of original production soda ash, make the calcining tail gas that produces in the calcination process obtain recycle, production technique is simple, flow process is short, has reduced greenhouse gases CO
2Discharging, improved production efficiency and output, can obtain good productivity effect and environmental benefit.
