A built-in synthetic leather lean terminal heating system and method

Abstract

The invention provides a built-in synthetic leather lean terminal heating system, which includes a natural gas flue gas generating chamber, a natural gas burner, a hot air distribution duct, a circulating air guide duct in the box, an air preheater and an automatic temperature uniform distribution system. Control system; the outlet of the natural gas burner is connected to the inlet side of the natural gas flue gas generating room; the hot air equalizing conduit is fixed in the natural gas flue gas generating room, and its hot fluid inlet side is connected to the flue gas outlet channel of the natural gas flue gas generating room; The left and right inlets of the inner circulation air duct are connected to the hot air equalizing duct, and the frequency conversion circulation fan is used as the power device at the connection. The hot air at the outlet side of the inner circulation air duct contacts the product to be dried and is discharged out of the box; The hot fluid side inlet of the air preheater is connected to the exhaust gas outlet of the box; the cold fluid side is fresh air, and the outlet is connected to the air inlet side of the natural gas flue gas generating chamber. The invention does not need to use a heat exchanger, not only reduces wind resistance, but also can reduce heat loss in 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...
