The utility model is mainly composed of a condenser and an evaporator. The utility model is characterized in that a brine pipe of which the upper part is provided with a throttling spray head is arranged at the middle part of an evaporation chamber. A blocking liquid cap is arranged on a spray head, and an allocation dish is arranged under the spray head. An adjusting valve is arranged on an outside brine inlet pipe. The utility model has the advantages of compact conformation, high efficiency of the flash evaporation and convenient operation of the throttling governing and running. Fresh water is prepared by the utility model through direct flash evaporation of the hot brine and warm water discharge, which is not only a new technology of developing fresh water resource, but also is a new technology of energy saving.
Description
The utility model relates to the direct flash distillation desalting equipment of a kind of external regulation type pipe core throttle-type low temperature exhaust heat salt solution.It belongs to the improvement of saline-water reclamation water distilling apparatus.
The direct flash distillation desalination of low temperature exhaust heat salt solution, be to introduce in the vaporizer with special construction through the salt solution (comprising hot sea water, hot brackish water or thermal technology industry water coolant) of heating to evaporate, this vaporizer is communicated with vacuum system, its internal pressure maintains below the pairing saturated vapor pressure of hot salt brine temperature, then hot salt brine flash distillation voluntarily in vaporizer, discharge steam and salt solution self cooling, steam forms required freshwater product through condensation.
At present, the saline-water reclamation flash distillation plant all is a multi-stage type salt solution circular form, the device of this pattern, and its advantage is that efficiency of utilization is higher.And weak point is: one. the device structure complexity, be difficult for lighting, and also be not easy to utilize waste heat; Two. salt solution is to enter evaporator room and realize flash distillation by being arranged on throttle orifice on the vaporizer walls at different levels, because in operation size that can not the free adjustment throttle orifice in service, so red-tape operati inconvenience; Three. because throttle orifice is arranged on the wall of evaporator room, cause the evaporator room space availability ratio unbalanced, steam production is big near the throttle orifice wall, and mist entrainment is also high.
In order to overcome the above-mentioned weak point of existing saline-water reclamation device, the purpose of this utility model is to provide a kind of external regulation type pipe core throttle-type low temperature exhaust heat salt solution direct flash distillation desalting equipment.This device not only is suitable for utilizing waste heat; compact construction; and has a flash efficiency height; can under halt condition not, carry out the characteristics such as adjusting of flash distillation amount from the outside; therefore be specially adapted to the desalination of low temperature exhaust heat salt solution, brackish water, handle as the desalination of the brackish water after boat diesel engine jacket water, factory's warm water discharge and the solar heating etc.
In order to achieve the above object, the utility model is realized by following proposal.It is to be passed through mutually with a vertical-type evaporator by a horizontal pipe bundle condenser to form that the utility model is mainly constructed, outward appearance is looked type like " T " word shape, place top shell-and tube condenser, one end housing body is provided with advancing of water coolant, outlet, on the end face of housing an interface is set so that link to each other with vacuum system, the bottom surface of housing is provided with the fresh water collection and puts mouth, evaporator room top at vertical-type evaporator is provided with scum dredger, be provided with steam baffle on the scum dredger, the vaporizer sidewall has visor, strong brine outlet and liquidometer, sewage draining exit is established in the vaporizer bottom surface, it is characterized in that: the salt water inlet pipe places the central authorities of vaporizer, pipe end is positioned at more than the liquid level, under the scum dredger, pipe end is provided with the throttling shower nozzle, the brine distribution dish that downward inclination angle becomes 15 °～20 ° is set on the tube wall under the shower nozzle, is provided with liquid-blocking cap on the shower nozzle, on the salt water inlet pipe of vaporizer outside, be provided with variable valve.
Accompanying drawing is the utility model structural representation that is used for single stage flash.1 is the vacuum Link Port among the figure, and 2 is condenser, and 3 is cooling water outlet, 4 is entrance of cooling water, and 5 is water outlet, and 6 is vaporizer, 7 is liquid-blocking cap, and 8 is shower nozzle, and 9 is distributing disc, 10 is variable valve, and 11 is brine tube, and 12 is sewage draining exit, 13 is liquidometer, and 14 is the strong brine relief outlet, and 15 is visor, 16 is scum dredger, and 17 is steam baffle.
The utility model is described in further detail below in conjunction with accompanying drawing.Condenser and vaporizer, they all belong to the chemical industry single devices, and structure is comparatively simple, and processing and manufacturing is easy.The utility model is combined into them " T " font shape.Set liquid-blocking cap (7), shower nozzle (8) and distributing disc (9) in vaporizer, their shape and size and mutual position dimension lot of essential factors are key problem in technology of the present utility model.Shower nozzle can adopt mechanical type, and existing certain resistance has suitable handling capacity and good flash distillation effect again.Distributing disc requires liquid distribution even, is beneficial to the liquid level renewal and flows, and distance is wanted suitably between liquid-blocking cap and the shower nozzle, can guarantee to shelter from the salt solution that shower nozzle sprays, and can be beneficial to the ascension of steam again.The variable valve that is provided with on the salt water inlet pipe (10) can be realized freely opening reaching the adjusting purpose according to the number of brinish temperature, treatment capacity.
The utility model realizes that brinish desalination process is: have certain temperature (50～60 ℃) hot salt brine, by pump delivery,, partly vaporize from the shower nozzle ejection in the flash distillation mode through variable valve, Qi Hua salt solution does not flow to the evaporator room bottom after liquid-blocking cap, liquid-distributing disk further evaporate.The steam that rises passes scum dredger and enters condenser and form fresh water and put mouth from collection and be expelled to Receiving bin.The strong brine that flow to the evaporator room bottom is down discharged from the strong brine relief outlet by liquid level control requirement.
The utility model has following 5 enthusiasm at least, one. utilize hot salt brine, the direct flash distillation of warm water discharge to produce fresh water, being a new technology that reclaims the exploitation Freshwater resources, is again a power-saving technology, and development marine economy and solution water shortage problem are had important value; Two. compact equipment is reasonable, and range of application and use occasion have been opened up in lighting greatly; Three. because salt solution carries out flash distillation in processes such as sprinkling, percussion, expansion and continual renovation liquid level, so the flash efficiency height; Four. the pipe core throttling set has reached the balanced purpose of utilizing of flashing chamber spatial, has realized that steam rises evenly the Optimizing operation that mist entrainment is few; Five. realize the purpose of free adjustment amount of restriction by variable valve, be convenient to the operation operation.
The fresh water that the utility model not only can be used for the warm water discharge of a large amount of factories reclaims, the desalination of arid area Kucheng's water, and can be used for the direct desalination of diesel cylinder sleeve hot sea water on the boats and ships.These all can obtain good result.
