Background technology
Salt manufacturing industry and salt chemical engineering industry bittern concentrate and generally adopt the multiple-effect vacuum evaporator at present, and the indirect steam that evaporation produces adopts and repeatedly utilizes principle, and afterbody indirect steam and on-condensible gas are got rid of by vacuum plant condensation, compression.Be limited to the restriction of evaporation temperature difference motive force, indirect steam utilizes number of times limited, and well mine salt enterprise has used five effects at most at present, and sea salt enterprise has used quadruple effect at most.Its afterbody indirect steam heat energy wave in vain is useless, and needs a large amount of water quench and large-scale air extractor (vacuum plant) to get rid of gas, to form vacuum state.Heating steam needs to continue steam supply with large-sized boiler, needs to consume a large amount of fuel.Therefore energy consumption is high, and continuing steam supply needs coal-fired or the natural vapour etc. that burns, and produces a large amount of three waste discharges thus.The use of a large amount of cooling waters is also unavoidably discharged the secondary pollution of formation because of the restriction of concentration rate.The multiple-effect vacuum evaporation technology is because the crystallization temperature of each jar is all inequality, and product salt crystal particle diameter major part is distributed in 0.1-0.4mm, and granularity is less, the granularity dispersiveness is very big, and the thickness inequality needs to increase anti-caking agent, do not lump with maintenance, its product salt does not belong to green health salt.So present multiple-effect vacuum evaporation technology, energy consumption height, big, the poor product quality of pollution.
Mechanical compression type thermo-compression evaporation device solves the high difficult problem of energy consumption, eliminated pollution substantially, product matter quality promotes, and can produce the green health salt that does not add anticaking agent, improves people's living standard.Its principle is: heat pump is that a kind of high potential that utilizes makes heat flow to the device of high-order thermal source from low level heat energy.Though heat pump will consume a certain amount of high potential, the heat of being supplied with is the high potential that consumes and the summation of the low-grade heat of absorption, so adopts heat pump assembly can save high potential.The operation principle of heat pump is identical with refrigeration machine, all is by the contrary periodic duty of hot machine.During the work of mechanical compression type heat pump, at first adopt and give birth to Steam Heating bittern to boiling point, low-temp low-pressure indirect steam from vaporization chamber is sucked by compressor, adiabatic compression effect by compressor, improve the pressure and the saturation temperature of indirect steam, send the heating clamber of former vaporization chamber then back to, use as heating steam.Compressor consumes certain available energy in this process.Heating steam enters behind the heating clamber and the bittern heat exchange, evaporates moisture content, i.e. indirect steam.Indirect steam is that compressor sucks, and forms cyclic process.
But present bittern concentrates with mechanical compression type thermo-compression evaporation device, and fire coal or oil burning boiler are mainly adopted in the generation of its steam, needs to consume a lot of non-renewable energy resources, and the discharging of burnt gas simultaneously is very serious to the pollution of environment, is unfavorable for environmental protection.
