the operating principle of low temperature evaporator
The whole system consists of vacuum pump and vacuum evaporation chamber, the vacuum degree is about 95%~97% (g -0。095~-0。097mpa), evaporation temperature under the condition of 32 DEG ~35 deg。 No need to pump material, making use of the system will be sucked into the negative pressure material evaporation chamber, spray into the mist, then the water is evaporated, Chen enters into the evaporation chamber by centrifugal pump, to achieve the required concentration after discharge。
Because of the viscosity of the concentrated liquid, so the screw pump。 The equipment can be equipped with a measuring instrument at the outlet, which can automatically discharge the material according to the density of the medium without touching the negative pressure to ensure the concentration control of the product。 The whole operation process is controlled by the program, the operation is simple, and the manpower is saved。
Advantages of low temperature evaporator
The traditional conventional evaporators in China are generally separated, which covers a large area and wastes space. The equipment does not need to use steam, directly connected to water, electricity can run, energy saving and environmental protection. With the heat pump cycle, cooling water by the system to generate their own compensation, save energy, reduce the cost of industrial wastewater treatment. The treated condensate can be recycled or used to achieve zero emissions. Enriched salt and heavy metals should be treated separately. (third party)
Special technology of low temperature evaporator
1. fully automatic control, water treatment effect is good, clean no smell.
2. do not need external heat source, through the use of special condenser operation of the heat pump to obtain the necessary heat energy, can be more than the conventional use of external heat source evaporator energy saving 50%, reduce operating costs. No external condensation system is needed to save circulating cooling water.
3. in the absence of contact with the negative pressure, according to the medium density measurement, automatic discharge.
4. the equipment is provided with an observation window, and the evaporation can be observed at any time.
5. when the equipment is running, it can be used for sampling and analysis of distilled liquor and concentrate.
6. stable equipment performance, continuous operation.
