Problems solved by technology

There are also a small number of units and institutions in China that have developed some flue-cured room heat exchangers that are compatible with biomass stoves, but the main problem is that the heat exchange efficiency is low. Due to the large range of heat supply required by flue-cured tobacco, it cannot meet the requirements of tobacco curing. , and problems such as excessive exhaust gas temperature, low output heat, uneven output temperature, and large heat exchanger resistance

Abstract

The invention relates to a heat exchanger of a tobacco flue-curing house, which comprises a furnace hot flue gas inlet, a heat exchange tube and an exhaust chimney, wherein the furnace hot flue gas inlet and the exhaust chimney are respectively connected with two ends of the heat exchange tube to form a hot flue gas inlet and outlet passage; the two ends of the heat exchange tube are respectively connected with a front gas collecting box and a back gas collecting box to form a flue gas inlet and outlet passage; the furnace hot flue gas inlet is communicated with the lower part of the front gas collecting box; a soot door is arranged on the front gas collecting box; and the exhaust chimney is arranged at the tail of the flue gas passage. The invention has large heat exchange area and high heat exchange efficiency; the flow resistance of flue gas in the heat exchanger of the tobacco flue-curing house is small, and the airflow rate is large; and the soot deposited in the heat exchanger of the tobacco flue-curing house can be cleared conveniently.

Description

technical field [0001] The invention relates to tobacco preparation equipment, in particular to a heat exchanger for a tobacco curing room. Background technique [0002] At present, most of the heat exchangers used in the flue-cured rooms of tobacco systems in the market are coal-fired furnace flue-cured rooms, and the use of biomass briquette flue-cured room heat exchangers is blank. There are also a small number of units and institutions in China that have developed some flue-cured room heat exchangers that are compatible with biomass stoves, but the main problem is that the heat exchange efficiency is low. Due to the large range of heat supply required by flue-cured tobacco, it cannot meet the requirements of tobacco curing. , and problems such as excessive exhaust gas temperature, low output heat, uneven output temperature, and large heat exchanger resistance. Contents of the invention [0003] In view of the above shortcomings, the present invention provides a heat e...
