Abstract

The invention discloses a heat recovery system of a paper machine. The heat recovery system comprises a blow tank, a propeller separator, a dirty hot water tank, a dirty hot water ejector pump, a middle tank and a plate heat exchanger, wherein the blow tank is fixedly connected with the propeller separator; a slurry collector is fixedly mounted below the propeller separator; the propeller separator is fixedly connected with an ejector condenser; the dirty hot water tank is arranged below the ejector condenser, and is in pipe connection with a dirty hot water filter; the middle tank is connected with a dirty hot water pump through a pipeline; the dirty hot water ejector pump communicates with the interior of the ejector condenser; and the plate heat exchanger is connected with a hot water tank through a line. The heat recovery system of the paper machine adopts various automatic machines, is high in automation degree, and recovers waste heat generated by the paper machine and recovers condensation water effectively; the waste heat is used for energy saving transformation; the energy saving effect is significant; and the economic benefit is considerable.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a heat recovery system of a papermaking machine. Background technique [0002] The paper industry is an important basic raw material industry that is closely related to the development of the national economy and social undertakings. It has the characteristics of capital-intensive technology and significant scale benefits. It is an important force in China's national economy and an important industry with sustainable development characteristics; the growth rate of annual consumption and production of paper and cardboard has been at a relatively high level since 2002. It can be said that China's paper industry is now It is in a high-speed growth period; it is expected that the output will reach or exceed 100 million tons in 2020, and there is still a lot of room for growth in the consumption of paper and cardboard in China; at the same time, the paper industry, as a ...
