TL;DR: In this article, the preparation method of an ionic adsorption resin moisture absorption coating of a pipe sleeve fin type heat exchanger is described, and the method comprises the following steps: crushing ionic adaption resin through a crusher to obtain ion exchange resin powder, soaking the powder in a moisture absorption saline liquor for 1-3 hours, and taking out, filtering, washing with clean water and drying to obtain modified ion exchange resins powder; uniformly mixing 30-80% of modified ion exchanger powder and 20-70% of powder paint according to mass
Abstract: The invention discloses a preparation method of an ionic adsorption resin moisture absorption coating of a pipe sleeve fin type heat exchanger. The method comprises the following steps: crushing ionic adsorption resin through a crusher to obtain ion exchange resin powder, soaking the powder in a moisture absorption saline liquor for 1-3 hours, and taking out, filtering, washing with clean water and drying to obtain modified ion exchange resin powder; uniformly mixing 30-80% of modified ion exchange resin powder and 20-70% of powder paint according to mass percent, and transferring the mixture to a static spraying cylinder; and statically spraying the surface of the pipe sleeve fin type heat exchanger in a static spraying chamber, and then, curing to obtain the coating. According to the coating, as the resin moisture absorption coating is uniformly distributed on the pipe sleeve fin type heat exchanger, the moisture absorption is high and the desorption temperature is low. Therefore, the moisture exchange efficiency can be improved, and indoor moisture can be dehumidified or indoor dry air can be humidified effectively.

TL;DR: In this article, a multi-channel heat exchange tube structure of the flue gas waste heat recycling heat exchanger has been proposed to improve heat exchange between flue gases and in-tube heat recycling fluid.
Abstract: The utility model discloses a flue gas waste heat recycling heat exchanger which comprises the following components: a flue gas inlet, a flue gas outlet, a waste heat recycling fluid inlet, a waste heat recycling outlet, heat exchange tubes, a tube board, a sealed box and an external wall. The heat exchange tube has a multi-channel structure which is provided with 2-4 elliptical or flat circulation channels through machining. The elliptical or flat circulation channels in a same heat exchange tube are separated to individual channels by in-tube projected ribs which are formed through squeezing and denting of the heat exchange tube. The heat exchange tubes are separately arranged in the horizontal direction and the vertical direction. The distance between the external walls of two adjacent heat exchange tubes in the horizontal direction is 1-10 millimeters, and the distance in the vertical direction is 3-10 millimeters. The multi-channel heat exchange tube structure of the flue gas waste heat recycling heat exchanger has the following advantages: improving heat exchange between flue gas and in-tube heat recycling fluid, improving flue gas waste heat recycling efficiency, reducing volume of the waste heat recycling device, reducing manufacturing cost, and overcoming the defects of low heat exchange efficiency and large volume in the flue gas waste heat recycling heat tube or finned tube.
