Description
The utility model belongs to water treatment and environmental technology field, particularly a kind of water treatment device that utilizes pressure reducing film distillation and heat pump latent heat recovery technology.
In space flight, military affairs, field of petrochemical industry and daily life, work, all to use water treatment device.Wherein the investment of producing water ratio, water quality, working cost and equipment always is what everybody was concerned about.At present, the utility model of existing many kinds of water treatment device.But the popular feature of these devices is: facility investment is big, handle sewage under the mal-condition (as urine etc.), and effect is bad.As being used for the thermoelectric integrated thin-film vapo(u)rization system (TIMES) of manned spacecraft environment control and life-support system, it can handle urine, but its uses perfluorinated sulfonic acid film and thermoelectric module, and price is very expensive.And present civilian many water treatment device, not only investment is not little, and raw material (as urine, the brackish water etc.) effect of handling under the mal-condition is bad.
The purpose of this utility model is for overcoming the weak point of prior art, designs a kind of water treatment device of new pressure reducing film distillation.Advantages such as it is little to have energy consumption, simple in structure, and price is low, and the raw material (as urine, brackish water etc.) under the processing mal-condition is effective.
The water treatment device of a kind of pressure reducing film distillation of the utility model design is formed by driving liquid pump, pre-treatment strainer, latent heat recovery unit, membrane module, vacuum pump and posttreatment filter and infusion pipeline and vacuum-lines; Wherein, infusion pipeline will drive that liquid pump, latent heat reclaim the unit, membrane module connects to form the raw material circulation loop successively, and vacuum-lines then reclaims unit, vacuum pump etc. with membrane module, latent heat and connects into a vacuum component.This latent heat reclaims the unit and is made up of the interchanger that fuses, heat pump and condenser.Drive between liquid pump and the latent heat recovery unit and also can be connected with the pre-treatment strainer by infusion pipeline.Downstream at said condenser also can be connected with posttreatment filter.
Said heat pump can be that electricity drives heat pump, also can be that heat drives heat pump.
Described interchanger can be various interchanger, but the high interchanger of heat transfer efficiency such as plate-fin heat exchanger preferably.
Strainer in the pre-treatment can be various forms of strainers, and the strainer in the aftertreatment is preferably activated charcoal filter.
Membrane module of the present utility model can be made by hydrophobic microporous membranes such as polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE)s.Heat pump can be the driving or hot driving heat pump of electricity.Interchanger adopts plate-fin heat exchanger, like this can enhanced heat exchange, reduce power consumption.
Working process of the present utility model is: raw material is by driving the liquid pump pumping, and sequential flow returns pump intake behind pre-treatment strainer (can save), interchanger and membrane module, circulate so again and again.From the steam that membrane module comes out, after the condenser condenses of flowing through, pass through posttreatment filter (can save) again and be filtered into water purification, vacuum pump is connected the downstream of condenser.
The general many aqueous solution with non-volatile substance of the utility model are the distillation process object.Use hydrophobic film, the nonwetting film of liquid, because capillary effect, the aqueous solution of film both sides all can not enter opposite side by fenestra.It utilizes the membrane distillation principle, film one side raw material phase temperature is higher than opposite side infiltration phase temperature, the temperature difference causes steam pressure difference, therefore steam molecule passes through fenestra, from the lateral movement of high-vapor-pressure side direction low-steam pressure, the condensation in the heat pump cool end heat exchanger of the steam of low-steam pressure side obtains water purification, and heat pump also can reclaim the latent heat that discharges in the condensation process.
The water treatment device of the utility model design can be used as the water treatment device under the mal-condition, as handling urine etc., also can be used for the water-purification plant of daily life, as handling tap water etc.Its producing water ratio depends primarily on the evaporation area and the vacuum tightness of film self, can be between 0.2kg/h-200kg/h; Handle back water purifying specific conductivity＜30 μ s/cm.
Producing water ratio of the present utility model big (0.2kg/h-200kg/h), water rate of recovery height (more than 90%), water quality good (specific conductivity is less than 30 μ s/cm).Can be used as the water treatment device under the mal-condition, as be used for processing urine, seawater/brackish water and sewage etc. such as space, ocean, field operations, ground observation, also can be places such as office, enterprises and institutions, school, villa, hotel, restaurant simultaneously purified tap water is provided.
