Corrugated plate to prevent compression deformation

Is a highly efficient and energy-saving heat exchanger has high heat transfer coefficient, compact structure, less material consumption, diversity, easy maintenance and other advantages, the application domain expands gradually, has been widely used in machinery, electric power, metallurgy, chemical, textile, beverage, urban heating and other industries and fields, showing a strong the competitiveness.

Plate heat exchanger with metal plate (general thickness of 05 ~ 1 0mm) for the heat exchanger components, from stainless steel, industrial pure titanium or other materials of thin plate. Usually, the plate is pressed into a variety of groove type or corrugated shape, which can increase the stiffness of the plate, to prevent the deformation of the plate under pressure, but also enhance the degree of turbulence of the fluid, increasing the heat transfer area. Each of the four corners of the plate with a hole around the plate around the hole and pressure sealing gasket groove, and according to the needs of a gasket placed in the hole week slot, to allow fluid or prevent fluid into the surface between the role of the channel. If the number of the sheet in accordance with the requirements of heat exchanger are orderly arranged in the bracket, and with a fixed plate and a movable plate by a pressing screw pressed in the adjacent plates formed by fluid passages, and the orifice of the four corners of the plate gasket. Each plate of AI Reed has at least two plates, and the heat transfer and pressure drop of the heat exchanger can be integrated by using the technology of thermal mixing. The inner bypass, the double channel technology and the unequal flow cross section assembly provide the perfect solution for the two sides of the medium flow rate difference. ARD plate heat exchanger has AB series, AM series, AL series, AP series, AS series, such as several large series of more than one hundred kinds of plates. Various models have deep ripple, shallow ripple, large angle, small angle, fully meet the needs of different users, special conditions can be designed and manufactured according to user needs.

In metal manufacturing, oil and water emulsions are used as refrigerants and lubricants. Oil and water emulsion can be reused several times, after the regeneration of the use of costly, but after a certain period of time, it is necessary to replace the new material.

Wastewater treatment is the goal of sharing out oily substance from the aqueous phase to minimize pollutants in water, in order to discharged to the sewage treatment equipment, or returned to the factory for reuse; and to highly concentrated oily ingredients, in order to facilitate the transmission, such as an incineration equipment. The thermal sharing process of the evaporation unit may well accomplish this task.

Process description

First, the crude and the free oil in the waste water are separated, and the waste water flows into the evaporation device after being filtered again. In a falling film evaporator, waste water is concentrated to about 30% of the test. This part of the equipment is heated by a mechanical steam compressor. In a forced circulation evaporator, waste water is highly concentrated. In most cases, evaporative condensate still contains oil, so it must be further processed before it is discharged to the sewage treatment plant or reused.
