Description

Self-cleaning ash plate type heat exchanger for high-salt-content waste liquid furnace

Technical Field

The utility model relates to a heat exchanger technical field specifically is a high contain self-cleaning ash plate heat exchanger that salt waste liquid stove was used.

Background

The high-salt-content waste liquid furnace has the advantages that the heat value of waste liquid is low, the temperature of a hearth is mainly maintained by burning natural gas, in order to save fuel consumption, an air preheater is arranged to improve subsequent waste heat recovery as much as possible, and the air preheater is provided with a traditional plate heat exchanger, a tubular heat exchanger and a jet flow heat exchanger. The traditional plate heat exchanger has good effect, but has poor dust cleaning effect, and the dust is deposited after the device is operated to influence the heat exchange effect, and even more, the device is stopped; the tube type heat exchanger has poor effect, the heat exchange area required under the same heat exchange effect can be increased, and the investment can be increased; the jet flow heat exchanger has good heat exchange effect, but the resistance drop of the air side is large. Therefore, the self-cleaning ash plate type heat exchanger for the high-salinity waste liquid furnace is provided.
