Plate heat exchanger is a highly efficient, energy-saving heat transfer equipment with high heat transfer coefficient, compact structure, less consumables, diverse forms, easy maintenance and many other advantages of gradually expanding applications have been widely used in machinery, electric power, metallurgy, chemical industry, textile, beverage, urban heating and other industries and fields show strong competitiveness.

Plate heat exchanger to metal plate (general thickness of 0.5 ~ 1.0mm) for the heat transfer element by stainless steel, industrial titanium or other pure The plate of material is pressed from the plate. Usually use the mold to press the plate into a variety of groove-shaped or corrugated shape to increase the rigidity of the plate to prevent deformation when the plate is pressed and also enhance the The degree of turbulence of the fluid increases the heat transfer area. Each plate has a hole in the corner of each plate. The gaskets act to allow or prevent fluid from entering the passage between the plates.

If several plates are arranged in sequence on a support according to the heat transfer requirements and the fixed and movable clamping plates are pressed together by the clamping screw on the adjacent The fluid channels are formed between the plates of the heat exchanger with the help of orifices and gaskets at the corners of the plates. Each size of Airead plate, with at least two plate types, uses thermal mixing technology to combine heat transfer and pressure drop of the heat exchanger. Keeps it running at the optimal operating point. Internal bypass, dual-runner technology and unequal flow cross-sectional assemblies provide the perfect solution for applications with large differences in media flow between the two sides. ARD plate heat exchanger has AB series, AM series, AL series, AP series, AS series and several other series of more than 100 kinds of heat exchanger. Plate Type. All models have deep corrugated, shallow corrugated, large angle, small angle, etc., to ensure that different users to meet the needs of the special conditions can according to the Users need to design and manufacture them specifically.

In metal manufacturing, oil-water emulsions are used as refrigerants and lubricants. Oil-water emulsions can be reused several times and are expensive to recycle, but after a certain period of time, they must be replaced with new ones. of materials up.

The goal of wastewater treatment is to share the oily material out of the water phase, and to minimize the contaminants in the water so that it can be discharged into the discharge in a treatment plant or returned to the plant for reuse; and the oily component should be highly concentrated to facilitate transfer to, for example, an incineration plant. . A heat sharing process for evaporation units may be well suited for this task.

Process Description

The wastewater is first separated from the coarse solids and free oil, and the wastewater, after being filtered again, will flow into an evaporation unit. In a set of descending membrane pre-evaporators, the wastewater is concentrated to about 30% of the attempt. This part of the plant is heated by an energy-efficient mechanical steam re-compressor. In a forced circulation evaporator, the wastewater is concentrated to a high degree. In most cases, the evaporation condensate still contains an oil component, so that before discharge to wastewater treatment equipment or reuse, it must be for further processing.
