The spiral plate heat exchanger should be chosen for its low resistance plate type. The plate type or corrugated type should be determined based on the actual needs of the heat exchange site. For environments with high flow rates and small allowable pressure drops, a plate type with high resistance should be selected. Based on the fluid pressure and temperature conditions, determine whether to choose a detachable type or a brazed type. When selecting the plate type, it is not advisable to choose plates with too small a single plate area, as this may result in too many plates, low flow velocity between plates, and a low heat transfer coefficient. This issue should be carefully considered for larger heat exchangers
To enhance the pressure-bearing capacity of the spiral plates, distance-maintaining columns are used to support them between plates. The fluid inlet and outlet on the cylinder can be either normal or tangential. China utilizes tangential acceptance, which has low fluid resistance and allows impurities to be easily washed out by the stainless steel reaction kettle. The use of reversible supports is more convenient, allowing the heat exchanger to be placed vertically or horizontally. The heat-exchanging fluids A and B flow through the two sides of the spiral plates, with one of the fluids flowing along the spiral channel from the outside to the inside and exiting through the central outlet. The temperature of the spiral plate heat exchanger depends on the selected material, which mostly includes carbon steel, stainless steel, aluminum, copper, and titanium
        As a device for transferring heat between two materials in industrial production, the spiral plate heat exchanger is widely used in the chemical industry. As a type of heat exchanger, it is also applied in various key areas of the chemical industry and is an important auxiliary production equipment in chemical production. Fouling of the spiral plate heat exchanger is a common failure mode. The measures to address fouling of the spiral plate heat exchanger include strictly following process procedures, maintaining good routine maintenance, and conducting regular cleaning.
