The invention relates to the field of heat exchange, and discloses a plate type preheater variable plate-tube spacing. The plate type preheater includes a supporting rack; the supporting rack is provided with multiple heat exchange plates and heat exchange baffle plates; the heat exchange plates are horizontally stacked on the supporting rack through the heat exchange baffle plates; the supportingrack is provided with multiple slide rods; the edges of the heat exchange plates and the heat exchange baffle plates are provided with slide grooves matching with the slide rods; elastic sealing rings with adjustable thicknesses are arranged between the heat exchange plates; the heat exchange baffle plates are slidingly installed on the supporting rack through elastic pressure devices; and the elastic pressure devices pressure control mechanisms which can adjust pressure automatically or manually. Through the plate type preheater, users can conveniently adjust the magnitude of the elastic sealing rings, and the integral thickness can be adjusted by the elastic pressure devices, so that the problems that the distances between the heat exchange plates cannot be adjusted can be solved.
Description
technical field [0001] The invention relates to the field of heat exchange, in particular to a plate preheater with variable plate-tube spacing. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is performed through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid, liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life. In the case of the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor area is one-third of that of the tube heat exchanger, and the heat recovery rate can be as high as 90%. [0003] At present, the existing plate heat exchangers, such as f...
