Description
(1) technical field
The utility model relates to the condensed steam water UTILIZATION OF VESIDUAL HEAT IN and pure water reclaims, and is a kind of condensate water flash distillation recycling equipment specifically.
(2) background technology
A lot of industrial production all is to utilize high temperature and high pressure steam to add media such as thermal material in heat power equipment, and for example the food boiling pot boils material or the like with Steam Heating.Absorb heat of vaporization through the softening water of handling in boiler and generate high temperature and high pressure steam, feed the heat power equipment heat medium, condense into liquid water after the steam release heat, this is a condensate water.Condensate water still has the temperature that is higher than under the normal temperature, and generally between 120 ℃ of 80 ∽, it is the extremely low pure water of salt content simultaneously.
Present condensate water recycling equipment no matter adopt open type or the enclosed recovery system all easily causes organic efficiency low, can not be recycled the heat energy and the pure water that have in the condensate water preferably, and cause the cavitation of condensate pump easily.
(3) summary of the invention
The purpose of this utility model is to solve problems of the prior art, proposes a kind of condensate water flash distillation recycling equipment.It can improve the heat energy recycle efficient that condensate water contains, the power consumption of conserve water resource and saving recycled in its entirety and simple to operate.
The utility model is achieved by following technical proposals.
Condensate water flash distillation recycling equipment, comprise boiler 1, heat power equipment 2, drain valve 3, flash distillation water tank 4, condensate pump 5 and steam jet pump 6, the steam (vapor) outlet of boiler 1 links to each other with steam jet pump 6 inlets, the bleeding point of steam jet pump 6 links to each other with the outlet of flash distillation water tank 4, the outlet of steam jet pump 6 links to each other with steam ports with heat power equipment 2, heat power equipment 2 exports the import that connects flash distillation water tank 4 through drain valve 3, and the delivery port of flash distillation water tank 4 links to each other with the import of condensate pump 5.
Laval nozzle is the convergent-divergent pipe in the described steam jet pump 6, and its inlet diameter is 30～60mm, and outlet diameter is 5～15mm, length is 50～80mm, exports to be that diffuser pipe, its inlet diameter are 8～20mm, outlet diameter is 50～100mm, and length is 500～1000mm.
It is very high to utilize boiler or external vapour source to supply with the pressure of steam, and heat power equipment is very low with the pressure that steam needs, and after can utilizing this pressure differential to extract the steam that the flash tank condensate water flashes off and supplying with vapor mixing, makes raise steam in diffuser pipe,
Heat power equipment uses.So just can be the steam utilization of the condensate water flash distillation of heat power equipment to heat power equipment itself.Remaining condensate water is delivered to boiler or other low warm users by condensate pump.
The throat of Laval nozzle produces high velocity air and vacuum in the steam jet pump import, the steam that flash distillation in the flash distillation water tank can be come out is extracted out also and the vapor mixing of supplying with, then at Laval nozzle diffuser adherence pressure, after reaching the steam pressure of heat power equipment needs, directly deliver to and go the heat release work done in the heat power equipment.
Described flash distillation water tank 4 is a cylinder, and diameter is 1000～2000mm, highly is 1500～3000mm, and wall thickness is 6～10mm.
Absolute pressure during the condensate water flash distillation is 0.02～0.09MPa, and corresponding saturation temperature is 60.09～96.71 ℃.
Steam becomes condensate water gradually after the heat power equipment heat release, drain into the flash distillation water tank through drain valve, and owing to the swabbing action of steam jet pump, pressure reduces in the flash distillation water tank, the corresponding corresponding reduction of saturation temperature, and condensate water can flash off a large amount of steam.Deliver to the hot equipment of using after these steam are extracted out by steam jet pump and after the vapor mixing of supplying with.The flash distillation water tank upper is the steam of flash distillation, and the bottom is a remaining aqueous water after the flash distillation, and these remaining condensate water are pumped to boiler or the hot equipment of other low temperature by condensate pump.
The utility model has the advantages that:
1, utilizes unnecessary steam pressure to extract flash-off steam, and its heat and water are made full use of in nearest heat power equipment.
2, reduce boiler oil expense or purchase the expense 15～22% of steam.
3, the remaining water yield reduces after the condensate water flash distillation, makes the power consumption of the water pump of transporting water reduce 20%.
