Built-in synthetic leather lean tail end heat supply system and method

Abstract

The invention provides a built-in synthetic leather lean tail end heat supply system which comprises a natural gas flue gas generation chamber, a natural gas combustion engine, a hot air equipartition guide pipe, a box internal circulating air guide pipe, an air pre-heater and a temperature uniform distribution automatic control system, wherein the outlet of the natural gas combustion engine is connected with the inlet side of the natural gas flue gas generation chamber; the hot air equipartition guide pipe is fixed on the natural gas flue gas generation chamber; the hot fluid inlet side of the hot air equipartition guide pipe is communicated with the flue gas outlet channel of the natural gas flue gas generation chamber; the left inlet and the right inlet of the box internal circulating air guide pipe are communicated with the hot air equipartition guide pipe, a variable-frequency circulating fan is adopted at the connection part to be used as a power unit, and hot air at the outlet side of the box internal circulating air guide pipe is in contact with the product required to be dried and then is discharged out of a box body; the hot fluid side inlet of the air pre-heater is connected with the tail gas outlet of the box body, fresh air is at the cold fluid side of the air pre-heater, and the outlet of the air pre-heater is connected with the air inlet side of the natural gas flue gas generation chamber. According to the invention, a heat exchanger is not used, the wind resistance is reduced, and the heat loss can be reduced during the heat supply process.

Description

technical field [0001] The invention relates to the field of natural gas combustion and the application of combustion devices, in particular to a heat supply technology suitable for uniform heat supply and high operational flexibility in the production process of synthetic leather. Background technique [0002] In some production processes of synthetic leather, flammable and explosive solvents will not volatilize, such as wet production process, after the washing process, most of the solvents in the drying process of synthetic leather are water, which will not burn or cause explosion. Explosion occurs due to the limit, so the safety requirement level for the drying medium is lower than that of the production process with flammable and explosive solvent volatilization. [0003] At present, most of the heating methods used in domestic synthetic leather production are centralized heating by coal-fired heat-conducting oil furnaces. There are also related patents on the natural g...
