The high salt sewage evaporation of a kind of self-cleaning of the present invention crystallization apparatus, the material water import department of its heater is provided with material water distribution orifice plate.
Compared with prior art, the invention has the beneficial effects as follows:
The high salt sewage evaporation of a kind of self-cleaning of the present invention crystallization apparatus has the following advantages:
1, the present invention is constantly flowed in heater heat-transfer pipe by self-cleaning medium and is constantly rubbed and collision with heat-transfer pipe inwall, the dirt being deposited on heat-transfer pipe inwall is peeled off, self-cleaning medium and dirt are discharged heating clamber with material water, thereby have reached the object of this device self-cleaning.
2, the present invention can solve the problem of scaling of heat transfer pipe, therefore can avoid the heat transfer deterioration of heat-transfer pipe, strengthen the heat exchange property of heater, improve the service efficiency of evaporated crystallization device, and reduced the workload of on-site maintenance, when having reduced consumption of chemical agent, alleviate the pressure of environmental pollution.
3, the present invention is simple in structure, and processing and fabricating cost is low, installs, dismantles easy.

Detailed description of the invention
Referring to Fig. 1, the present invention relates to the high salt sewage evaporation of a kind of self-cleaning crystallization apparatus, it comprises heater 1, jet pump 3, self-cleaning medium 4, Separation of Solid and Liquid chamber 5, evaporative crystallization chamber 6, vapour compression machine 7, strong brine pump 8 and material water pump 9, the outlet of described jet pump 3 is connected with the material water import of heater 1, the material water import department of described heater 1 is provided with material water distribution orifice plate 2, the material water outlet of described heater 1 is connected with the import of Separation of Solid and Liquid chamber 5, the solid outlet of described Separation of Solid and Liquid chamber 5 is connected with the injection entrance of jet pump 3, described self-cleaning medium 4 is arranged in the heat-transfer pipe of heater 1, the liquid outlet of described Separation of Solid and Liquid chamber 5 is connected with evaporative crystallization chamber 6, the steam (vapor) outlet of described evaporative crystallization chamber 6 is connected with the import of vapour compression machine 7, the outlet of vapour compression machine 7 is connected with the steam inlet of heater 1, the strong brine outlet of described evaporative crystallization chamber 6 is connected with the import of strong brine pump 8, the crystal of separating out and material water after a small amount of concentrated through brine pump 8 deliver to down together with treatment process, the material water outlet of described evaporative crystallization chamber 6 is connected with the import of material water pump 9, the outlet of material water pump 9 is connected with the material water import of heater 1.
Operation principle: material water 10 is entered the material water import of heater 1 by the import high velocity jet of jet pump 3, under the draw of jet pump 3 high velocity jet, self-cleaning medium 4 is carried secretly and is sent in heater 1 by injection, after material water distribution orifice plate 2, self-cleaning medium 4 is uniformly distributed in the heat-transfer pipe of heater 1, self-cleaning medium 4 constantly rubs and collision with the heat-transfer pipe inwall of heater 1 in flow process together with material water 10, at said process, self-cleaning medium 4 strips down the dirt accumulating on the heat-transfer pipe inwall of heater 1, thereby reach the object of self-cleaning antiscale, the Steam Heating that material water 10 is exported by vapour compression machine 7 in the heat-transfer pipe of heater 1, material water 10 after heating together enters Separation of Solid and Liquid chamber 5 from heater 1 material water outlet with self-cleaning medium 4, in Separation of Solid and Liquid chamber 5, self-cleaning medium 4 separates with heated material water 10, the injected pump 3 of the solid outlet of self-cleaning medium 4 after separation through Separation of Solid and Liquid chamber 5 again injection enters in heater 1, thereby recycled, material water 10 after separation directly enters the interior cooling evaporation in evaporative crystallization chamber 6 through the liquid outlet of Separation of Solid and Liquid chamber 5, the indirect steam that evaporation process produces heats material water 10 as the heating steam of heater 1 after vapour compression machine 7 pressurizations heat up, rear this part steam of heater via 1 becomes condensate water 11 and reclaims, material water 10 concentration after the interior evaporation in evaporative crystallization chamber 6 increase, its contained salinity will crystallization, the crystal of separating out and strong brine 12 after a small amount of concentrated through brine pump 8 deliver to down together with treatment process, the interior most of material water 10 after concentrated in evaporative crystallization chamber 6 is again sent in heater 1 and is recycled by material water pump 9.
