Description of the embodiments
The invention is described in further detail below with reference to the drawings and examples.
As shown in fig. 1, a low-temperature atomization evaporator for wastewater is provided with an evaporator 1, a plate heat exchanger 2, a circulating booster pump 3, an air pump 4, an aeration head 5 and a jet device 6. The bottom of the evaporator 1 is provided with an aeration head 5, the aeration head 5 is connected with an air pump 4 through an air inlet 201, a waste water inlet 105 at the top of the evaporator 1 is connected with an expansion chamber 603 of the ejector 6, a water vapor outlet 202 at the top of the evaporator is connected with a water vapor inlet 203 at the top of the plate heat exchanger, and a residual waste water discharge outlet 108 is arranged at the bottom of the evaporator 1. The top of the plate heat exchanger 2 is provided with a waste heat circulating water inlet 106, the bottom of the plate heat exchanger 2 is provided with a waste heat circulating water outlet 107, an air outlet 204 at the lower part of the plate heat exchanger 2 is connected with an air suction port 604 of the jet device 6, and a waste water outlet 104 of the plate heat exchanger 2 is connected with a waste water inlet of the jet device 6. The inlet of the circulating booster pump 3 is connected with a recycling waste water outlet 101 and a waste water inlet pipe 102 at the lower part of the evaporator 1, and the outlet of the circulating booster pump 3 is connected with a recycling waste water and waste water inlet 103 of the plate heat exchanger 2.
The basic working principle of the low-temperature atomization evaporator for wastewater is as follows: the waste water is pressurized by the circulating booster pump 3 and enters the plate heat exchanger 2, heat exchange and temperature rising are carried out on the waste water and the circulating waste heat water in the plate heat exchanger 2, then the waste water is sprayed and atomized by the ejector 6 and enters the evaporator 1, atomized and evaporated in the evaporator 1, and water vapor enters the plate heat exchanger 2 from the water vapor outlet 202 of the evaporator 1 to be mixed with the circulating waste heat water, so that the waste water is subjected to heat exchange and temperature rising, and the secondary utilization of heat energy and the purification and utilization of the waste water into circulating water are achieved. During the operation of the equipment, air is aerated and evaporated through the air pump 4 and the aeration head 5, and finally the residual concentrated wastewater is discharged through the wastewater discharge outlet 108.
The waste heat circulating water of the plate heat exchanger 2 is waste heat water generated in the production of other equipment of an enterprise, and the whole process is to heat by utilizing the waste heat water, so that the waste heat is gasified at low temperature, and steam and electric energy are not needed. The aeration head 5 is connected with the air pump 4 to provide conditions for the low-temperature gasification of the wastewater. The vapor of the evaporator 1 is cooled by the plate heat exchanger 2 and then connected with the air suction port 604 of the ejector 6, so that the interior of the evaporator 1 is always in a negative pressure state.
