Description
Technical field
The present invention relates to sewage treatment equipment, especially a kind of waste water low-temperature atomizing evaporator.
Background technology
The discharge and improvement of waste water have been included on the daily production work of enterprise, and the waste water of high pollution high concentration is even more
The emphasis of enterprise governance.Processing high pollution at present, high-concentration waste water use the vapo(u)rization system and MVR of shell and tube forced circulation substantially
Evaporation technique, but not only power consumption is big for this technology, and the thermal efficiency is low, and steam consumption is big, and high equipment cost, bulky,
The serious application that restrict enterprise.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of waste water low temperature mists of simple structure and low cost
Change evaporator.
The present invention adopts the following technical scheme that.
A kind of waste water low-temperature atomizing evaporator, have evaporator, plate heat exchanger, cycle force (forcing) pump, air pump, aeration head and
Ejector, wherein：
The base of evaporator is equipped with aeration head, and aeration head is connected by the air intake of evaporator with air pump, evaporator top
The waste water inlet in portion is connected with the expansion chambers of ejector, and the water at the top of the steam outlet and plate heat exchanger at the top of evaporator steams
Vapor inlet is connected, and remaining waste water discharge port is arranged at the bottom of evaporator；
Have surplus heat circulating water intake at the top of the plate heat exchanger, and plate heat exchanger bottom has surplus heat circulating water outlet, board-like to change
The gas outlet of hot device lower part is connected with the air entry of ejector, the wastewater outlet of plate heat exchanger and the waste water inlet phase of ejector
Even；
The import of the cycle force (forcing) pump carrys out water pipe with the recycling wastewater outlet and waste water of evaporator lower part and is connected, and cycle adds
The outlet of press pump is connected with the recycling waste water and waste water inlet of plate heat exchanger.
It is cheap compared with the prior art, the advantages of the present invention are as follows simple in structure, it is energy saving.
Description of the drawings
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific implementation mode
Below in conjunction with drawings and examples, present invention is further described in detail.
As shown in Fig. 1, a kind of waste water low-temperature atomizing evaporator, have evaporator 1, plate heat exchanger 2, cycle force (forcing) pump 3,
Air pump 4, aeration head 5 and ejector 6.1 bottom of the evaporator be equipped with aeration head 5, aeration head 5 by air intake 201 with
Air pump 4 is connected, and the waste water inlet 105 at 1 top of evaporator is connected with the expansion chambers 603 of ejector 6, and the water at the top of evaporator steams
Vapor outlet 202 is connected with the water vapour import 203 at the top of plate heat exchanger, and remaining waste water discharge port is arranged at the bottom of evaporator 1
108.The top of the plate heat exchanger 2 has surplus heat circulating water intake 106, and 2 bottom of plate heat exchanger has surplus heat circulating water outlet
107, the gas outlet 204 of 2 lower part of plate heat exchanger is connected with the air entry 604 of ejector 6, the wastewater outlet of plate heat exchanger 2
104 are connected with the waste water inlet of ejector 6.The recycling wastewater outlet of the import and 1 lower part of evaporator of the cycle force (forcing) pump 3
101 and waste water come water pipe 102 be connected, recycle force (forcing) pump 3 outlet and plate heat exchanger 2 recycling waste water and waste water inlet
103 are connected.
The basic functional principle of waste water low-temperature atomizing evaporator is：Waste water enters board-like change by the cycle pressurization of force (forcing) pump 3
Hot device 2 heats up with cycle remaining hot water heat exchange in plate heat exchanger 2, enters evaporator 1 using 6 jet atomization of ejector,
1 atomization evaporation of evaporator, vapor enters plate heat exchanger 2 by the steam outlet 202 of evaporator 1 to be mixed with cycle remaining hot water
It closes, heats up to wastewater heat exchange, become the purification utilization of recirculated water with the secondary use and waste water that reach thermal energy.In equipment running process
Middle air carries out aeration evaporation by aeration head 5 by air pump 4 to the waste water in evaporator, and last remnants density wastewaters are by useless
Water discharge port 108 is released.
The waste heat circulation water of plate heat exchanger 2 is the remaining hot water generated in enterprise's other equipment production, and whole process is profit
It is heated with this remaining hot water, low temperature gasification does not need steam and electric energy.Aeration head 5 is connected with air pump 4, is that waste water is low
Wetization provides condition.The vapor of evaporator 1 by plate heat exchanger 2 cool down after again with 604 phase of the air entry of ejector 6
Even, cause always to be in a state of negative pressure in evaporator 1.
