Heating furnace fused salt heating flue waste heat recovery device and method

Abstract

The invention discloses a heating furnace fused salt heating flue waste heat recovery device and a method, and belongs to the technical field of liquid storage tanks. The heating furnace fused salt heating flue waste heat recovery device comprises a liquid storage tank, five connected inner pipes are fixedly installed in the liquid storage tank, one end face of the liquid storage tank is fixedly connected with an inlet and an outlet, one end of the liquid storage tank is fixedly connected with a short pipe, the other end of the short pipe is fixedly connected with a side tank body, and one end surface of the liquid storage tank is fixedly connected with a connecting pipe. According to the heating furnace fused salt heating flue waste heat recovery device and the method, high-temperature flue gas of the liquid storage tank can be guided into a fused salt heating box through a conveying connecting pipe, hot air is replaced with fused salt, heat is replaced out, the temperature of a flue gas pipe is lower than 500 DEG C, the service life of a flue pipeline is greatly prolonged, in addition, the heat stored in the high-temperature fused salt can be reused, the heat is fully utilized, and therefore a sufficient power source is provided.

Description

technical field [0001] The invention relates to the technical field of liquid storage tanks, and more specifically, relates to a waste heat recovery device and method for a molten salt heating flue of a heating furnace. Background technique [0002] The cooling of liquid storage tank components mainly includes water cooling and vaporization cooling. Water cooling uses the temperature rise of water to absorb heat. [0003] At present, most of the waste heat generated in the working process of the existing liquid storage tanks cannot be fully recycled. Some only use the superheated steam generated by the vaporization cooling device. At the same time, the higher flue gas cannot be fully utilized, which also causes a lot of waste heat waste, and the temperature of the flue gas with a higher temperature is mostly over 500 degrees, which will greatly damage the flue gas pipeline. Shorten its service life, for this reason, we have designed a heating furnace molten salt heating flu...
