Description

A kind of synthetic leather dry process production line natural gas direct combustion heater

Technical field

The utility model belongs to synthetic leather dry process production line accessory field, specifically, relates to a kind of synthetic leather dry process production line natural gas direct combustion heater.

Background technology

Synthetic leather is produced in (comprising dry method and wet processing) process needs to use in a large number heat energy, and the most synthetic leather of China enterprise heating equipment is all with coal-burning boiler mode of heating at present.Coal-burning boiler uses in service in reality, the thermal efficiency is low, and energy waste is large, and dust exhausting concentration is large, and the sulfur content of coal is high, serious to atmosphere pollution.Especially the contradiction of energy supply and demand and environmental pollution in recent years.

The natural gas direct combustion type efficiency of heating surface is high, low to atmosphere pollution, has good environmental-protecting performance.Natural gas is current the most clean a kind of fuel in the world, its sufficient combustion, and without producing ash and sulfur dioxide, after burning, main composition is water vapour.Meanwhile, gaseous fuel is carried by pipeline, can reduce greatly labour intensity, improves working conditions, and reduces operating cost.

Traditional dry process production line uses the heat supply of coal-burning boiler conduction oil all to complete in oven interior, if using natural gas straight combustion technology to complete heat supply in oven interior will encounter problems, because can produce flammable explosive gas in all combustion heat-exchange process of combustion of natural gas device, this gas is full of baking oven, will cause that fire even explodes once concentration and temperature reach certain condition, have serious security threat.

Summary of the invention

The technical problems to be solved in the utility model is to overcome above-mentioned defect, provides a kind of reasonable in design, and manufacture craft is simple, can ensure that dry process production line normally produces, and ensures the synthetic leather dry process production line natural gas direct combustion heater of production safety.

For addressing the above problem, the technical scheme that the utility model adopts is:

A kind of synthetic leather dry process production line natural gas direct combustion heater, is characterized in that: comprise mixing chamber, be provided with heater, air inlet and return air inlet in mixing chamber, described return air inlet is communicated with return air actuating unit; Described mixing chamber is communicated with heat exchanger; Described heat exchanger is arranged in baking oven, and heat exchanger is by the pipeline connection return air actuating unit of penetration heat interchanger, and on the outer surface of heat exchanger, is provided with hot gathering-device, and hot gathering-device has heat distribution device by pipeline connection; One side of described baking oven is provided with exhaust outlet.

As a kind of technical scheme of optimization, described heater comprises the combustor being communicated with natural gas line, and is connected and runs through the burner noz(zle) of mixing chamber with combustor, is provided with the combustion chamber corresponding with burner noz(zle) in mixing chamber, a side opening of combustion chamber.

As a kind of technical scheme of optimization, described return air actuating unit is the blower fan that is communicated with respectively heat exchanger and mixing chamber.

As a kind of technical scheme of optimization, described hot gathering-device comprises the collecting hood covering on heat exchanger, and collecting hood has blower fan by pipeline connection, and blower fan is by pipeline connection heat distribution device.

Owing to having adopted technique scheme, compared with prior art, in heat exchanger of the present utility model, high-temperature part is directly by pipeline connection mixing chamber, low temperature part is communicated with heat distribution device by collecting hood, realize heat exchanger high-temperature part and low temperature part is isolated completely, stopped inflammable gas and directly contact the possibility of high-temperature gas.In addition, the gas in baking oven passes through heat exchanger heats, then sends into heat distribution device through collecting hood and blower fan, and heat is evenly distributed in baking oven.Waste gas in baking oven is sent into heat recovery system by exhaust outlet, and the heat energy reclaiming in heat recovery system returns in mixing chamber, has realized the recycling of heat energy, reaches energy-conservation object.

The utility model meter is reasonable, and manufacture craft is simple, can ensure that dry process production line normally produces, and ensures production safety.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
