Zhejiang Ruipu Industrial Co., Ltd. is a company specializing in the production of synthetic leather. Since synthetic leather products or semi-finished products need to be dried, the heating source of the drying equipment comes from the heat transferred from the boiler after heating. On the one hand, the large amount of heat generated when the flue gas is emitted is not effectively used. On the other hand, the enterprise has to consume 35 tons of coal per day for the heating boiler.
Can we absorb waste heat through any equipment and reuse the absorbed heat in the company's heating system to re-use it, not only turning waste into treasure, but also reducing coal consumption? The company learned through multiple parties that it spent more than two million yuan in March this year to buy two waste heat recovery heaters and related equipment from Shanghai to absorb the heat generated by the boiler. As the waste heat recovery heater absorbs heat, the temperature of the water vapor inside it can reach more than 100 degrees, and the generated heat can be incorporated into the enterprise heating system. Enterprises can burn 5 tons less coal per day, saving 3,500 yuan in cost.
It is reported that from January to May of this year, Zhejiang Rip Industrial Co., Ltd.'s industrial output value increased by nearly 20% compared with the same period of last year, while energy consumption per million yuan decreased by 14.16% year-on-year.
Calcium Stearate is a carboxylate salt of calcium, classified as a calcium soap. The salt is a component of some lubricants, surfactants, as well as many foodstuffs. Calcium stearate is a waxy material with low solubility in water, unlike traditional sodium and potassium soaps.
Used as heat stabilizer for PVC and lubricant for many kinds of plastic processing, mold release agent, etc. In hard products, it is used with salt-based lead salts and lead soap to improve the gelation speed. It is also used in food packaging, medical instruments and other soft films and instruments that require non-toxic properties. It can also be used as halogen absorber for polyethylene and polypropylene to eliminate the adverse effects of residual catalyst on color and stability. In the rubber processing as plasticizer, can make natural rubber and synthetic rubber softening, but almost no effect on vulcanization. It is also used as lubricant for polyolefin fiber and molding plastic, thickening agent for grease, waterproofing agent for textile, smoothing agent for paint, plasticizer for making plastic records, etc. It is also used in the production of pencil cores and in the pharmaceutical and spice industries.
