Problems solved by technology

[0002] At present, the temperature of the flue gas discharged from the waste gas incinerator needs to be controlled below 250°C. Due to the high temperature of the flue gas in the incinerator, efficient and reasonable heat exchange is required, and the heat is often wasted in the heat exchange process.

Abstract

The invention relates to a quaternary body air heating furnace. A circulating air inlet, a circulating air outlet, a fresh air supplementing port, a waste air port, a heat exchanger, a filter, a combustion engine, a smoke discharge chimney and a circulating fan, wherein the circulating air inlet is arranged at the lower portion of the air heating furnace, the waste air port is arranged at the upper portion of the air heating furnace, the combustion engine is arranged under the waste air port, the heat exchanger is arranged in the middle of the air heating furnace, and the filter is arranged at the rear portion of the heat exchanger. The quaternary body air heating furnace is clean and free of pollution. Due to the complete combustion, the smoke emission of the air heating furnace does not meet the national environment-protection requirement. By adopting an indirect type smoke heat exchange structure, heated circulating air is not in contact with smoke, cleaning is kept, the combustion engine automatically shuts down or reduces heat power when the temperature in the air heating furnace reaches to a set temperature, and the combustion engine is automatically started and the output air temperature can be accurately controlled when the temperature in the air heating furnace is lower than the set temperature.

Description

technical field [0001] The invention relates to a hot blast stove for drying and heating, in particular to a quaternary hot blast stove. Background technique [0002] At present, the temperature of the flue gas discharged from the waste gas incinerator needs to be controlled below 250°C. Due to the high temperature of the flue gas in the incinerator, efficient and reasonable heat exchange is required, and the heat is often wasted in the heat exchange process. Contents of the invention [0003] In order to solve the above problems, the present invention provides a quaternary body hot blast stove with simple structure, high heat exchange efficiency, good filtering effect, energy saving and environmental protection. [0004] The technical solution of the present invention is: the hot blast stove is provided with a circulating air inlet, a circulating air outlet, a fresh air outlet, a waste gas outlet, a heat exchanger, a filter, a burner, an exhaust chimney and a circulating ...
