Description
Technical field
The utility model relates to a kind of fertilizer production equipment field, is specifically related to a kind of reactive tank exhaust heat-energy recycling system.
Background technology
Produce S-based compound fertilizer and generally first carry out after conversion reaction generates sal enixum slip delivering to subsequent handling with sulfuric acid and Repone K, also discharge the tail gas that contains hydrogen chloride gas simultaneously, after cooling absorbs, become salt acid product, instead of directly discharge.Although conversion reaction process is micro-heat release, but because hot slip and the tail gas that contains hydrogen chloride gas need constantly to discharge and take away a large amount of heat energy, easily reduce conversion reaction temperature and cannot normally produce, conventionally using steam heating to keep conversion reaction temperature, guaranteeing to reach the transformation efficiency index of regulation.In theory every production 1000kg S-based compound fertilizer need to consume 150kg(pressure be 0.8MPa) steam, the steam of supply produces with bunker coal.Outflow temperature is that the exhaust heat-energy of 100 DEG C is not utilized, and generally draws through the hydrochloric acid that falling-film absorber is lowered the temperature and circulation absorption production concentration is 31% then up to standard emptying by cigarette fontanel with induced draft fan.Therefore existing conversion reaction, in having consumed a large amount of coals and water resources, has been wasted again a large amount of utilized heat energy, and has coal-fired environmental pollution and the resource consumption causing.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of chemical fertilizers production device of recycling reactive tank exhaust heat-energy.
For reaching above object, the technical scheme that the utility model is taked is:
A kind of reactive tank exhaust heat-energy recycling system comprises Repone K hopper, belt electronic scale, reactive tank, sub-cylinder steam, sulfuric acid storage tank, sulfuric acid preheater, falling-film absorber, hydrochloric acid circulation groove, salt acid circulating pump, hydrochloric acid storage tank and induced draft fan, described belt scale is arranged at conversion tank top, Repone K hopper is arranged at directly over belt scale, described sub-cylinder steam is through pipeline communication conversion tank, described sulfuric acid preheater is shell shell and tube heat exchanger, described sulfuric acid storage tank outlet is connected with conversion tank through sulfuric acid preheater shell side, described conversion tank connects the input terminus of falling-film absorber through the tube side of sulfuric acid preheater, the output terminal of described falling-film absorber connects hydrochloric acid circulation groove, described hydrochloric acid circulation groove connects the input terminus of falling-film absorber through salt acid circulating pump, the output terminal of described hydrochloric acid circulation groove connects hydrochloric acid storage tank through salt acid circulating pump.
Further, between the tube side of described falling-film absorber and sulfuric acid preheater, be provided with induced draft fan.
Further, between described falling-film absorber and sulfuric acid circulation groove, be provided with induced draft fan.
Again further, the open to atmosphere induced draft fan of the external company of described sulfuric acid circulation groove upper space.
Take after above technical scheme, the beneficial effects of the utility model are:
Utilize induced draft fan to introduce in sulfuric acid well heater sulfuric acid preheating passing into high-temperature tail gas in the conversion tank of high-temperature steam, reduced steam, effectively utilized the heat energy of tail gas; The tail gas of gas containing hydrogen chloride enters falling-film absorber after heat exchange cooling, has reduced the consumption of the water coolant passing in falling-film absorber.
The utility model has been recycled the heat energy of sulfuric acid and Repone K conversion reaction tail gas, reduce the steam consumption in conversion reaction process, reduce the coal consumption of follow-up baking operation, the power consumption of recirculated cooling water in induced draft and hydrogen chloride gas absorption process, stablize technic index, improve output and quality, reduced cost and environmental pollution.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: Repone K hopper 1, belt electronic scale 2, reactive tank 3, sub-cylinder steam 4, sulfuric acid storage tank 5, sulfuric acid preheating 6, falling-film absorber 7, hydrochloric acid circulation groove 8, hydrochloric acid circulation 9, hydrochloric acid storage tank 10, induced draft fan 11.
Embodiment
