Air compressor (abbreviation air compressor machine) is the most widely used dynamic origin of industrial circle, is widely used in mining, machine-building, building, weaving, petrochemical industry and other need the place of Compressed Gas.In most of production enterprises, its energy resource consumption accounts for the 10%-35% of whole energy resource consumptions.Because air compressor machine is by strong compression, the part mechanical energy of prime mover to be changed into the pressure energy of gas, therefore when producing pressure-air, can discharge amount of heat, the Compressed Gas of high temperature is carrying a large amount of heats, in the process that these heats can be carried at Compressed Gas, scatter and disappear in vain, cause the waste of energy.Actual detection discovery, air compressor machine is discharged the gas mixture temperature of body generally up to 80-100 ℃, if heat is discharged not in time, can cause serious damage to equipment, and affect gas producing efficiency.At present, generally the mode by air-cooled (cooling blower) or water-cooled (cooling tower) is thrown into this part heat in air, has caused the significant wastage of the energy.But still exist high temperature compressed air and water heat exchange to be faced with the problems such as heat exchange efficiency is low, air-pressure drop is large.
Utility model content
The purpose of this utility model produces thus, proposes a kind of air to water heat exchanger.By reclaiming the waste heat in air compressor high-temperature gas, both can recover energy to greatest extent, reduce energy consumption, can improve again the gas producing efficiency of air compressor machine, can also save the energy, protection of the environment, reduce costs, the extension device life-span.
The utility model is realized the technical scheme that above-mentioned purpose takes: a kind of air to water heat exchanger, mainly by housing, the little header of intaking, the little header of water outlet, water pipe, formed, in the chamber upper end of housing, be connected with the little header of water outlet, in the chamber lower end of housing, be connected with into the little header of water, in the cavity of housing, be provided with multilayer water pipe, it is coil-like that water pipe is serpentine, and the water inlet of every layer of water pipe is all communicated with the little header of water inlet, delivery port is all communicated with the little header of water outlet.
Water pipe described in the utility model is horizontal layout, in the curved bottom of " U " of every layer of water pipe shape
All be welded with post, the post other end is welded on respectively on the inwall in described shell chamber (7).
Water pipe described in the utility model is the withstand voltage steel pipe with aluminium matter aciculiform fin, the similar pine needle shape of fin shape.
The pipeline making that water described in the utility model is little and the little header of water inlet adopts one section of two ends to shut with blind plate.
Water pipe described in the utility model is horizontal layout.
The utility model is due to an air to water heat exchanger being installed on compressed gas transmission pipeline, by high-temperature gas and water at low temperature, carry out heat exchange, the energy dissipation that when efficiently solving high-temperature gas and carrying at a distance, heat loss causes, reclaimed to greatest extent energy, reduced energy consumption, improve the gas producing efficiency of air compressor machine simultaneously, extended the service life of equipment, and can also prevent the pollution of heat to environment.The energy that the waste heat reclaiming can be used as other field is used, and as being used for bathing etc. for heating water, therefore, has reached the object of saving the energy.

The specific embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1 with Figure 2: the air to water heat exchanger described in the present embodiment is arranged on high-temperature gas and carries front or enter before pressurized tank.Described air to water heat exchanger is mainly comprised of housing 7, the little header 9 of intaking, the little header 10 of water outlet, water pipe 8, and housing 7 is a prismatic sealed chamber, adopts steel plate to make.In the chamber upper end of housing 7, be connected with the little header 10 of water outlet, and be provided with hot water outlet 2 and delivery port flange 12 on the little header 10 of water outlet; In the chamber lower end of housing 7, be connected with into the little header 9 of water, and be provided with cooling water inlet 1 and water inlet flange 11 on the little header 9 of water inlet.The little header 10 of water outlet, the little header 9 of intaking can adopt the pipeline that shut with blind plate at one section of two ends to make.In the cavity of housing 7, be provided with water pipe 8, it is coil-like that water pipe 8 is serpentine, and two ends port is in same direction, and lay respectively in the little header 9 of water, the little header 10 of water outlet.Water pipe is all welded with post in the fixed form of housing 7 in the curved bottom of pipe " U " shape, and the post other end is welded on respectively on the inwall in shell chamber.Water pipe is horizontal layout, total some rows, and the water inlet of every drainpipe is all communicated with the little header 9 of water inlet, delivery port is all communicated with the little header 10 of water outlet, and gap, the junction full weld of pipe and header is shut.Water pipe 8 is the withstand voltage steel pipe with aluminium matter aciculiform fin 3, the similar pine needle shape of fin shape.The pipe of aciculiform fin is compared under equal length with light pipe, and heat exchange area can increase several times decades of times even, so can greatly improve heat exchange efficiency, the pressure drop of the fin convection cell of aciculiform simultaneously also affects less, does not cause air-pressure drop excessive.The effect of little header 9 of intaking is to collect the cold water that enters every drainpipe, and makes cold water enter equably water pipe, and the effect of the little header of water outlet is the water outlet that collects all water pipes, and water is flowed out in time, guarantees that output water temperature is relatively constant.Two ends at housing 7 are connected with respectively Concentric Reducers 4, and Concentric Reducers 4 is one section one large, a little pipeline, and stub end caliber is identical with housing 7 calibers, and microcephaly holds caliber identical with compressed gas transmission pipeline caliber; Tube connector 5 is and the duplicate segment pipe of compressed gas transmission pipeline, and its effect is to connect this heat exchanger and gas transmission pipeline, at the port of tube connector 5, is all welded with flange 6, and its effect is to be convenient to carry out flange connection with gas transmission pipeline.In order to improve heat-insulating property, whole device is carried out insulation with insulation material, tube connector 5, the little header 9 of intaking, the little header 10 rubber-plastic thermal insulation pipe outsourcing of water outlet, and Concentric Reducers 4 and housing 7 adopt polyurethane sandwich insulation.
During use: high-temperature gas in housing 7, water pipe 8 tube bank flows outside, carry out heat exchange with the cold water being entered by cooling water inlet 1 into entering again coil pipe after the little header of water, the cold water temperature after heat absorption raises, and flows in the little header of water outlet, through hot water effluent 2, flows out.High-temperature gas through with cold water heat exchange after, temperature reduces, reduced and environment temperature between the temperature difference, and then avoided the heat loss in course of conveying, thereby reached the object of recycling gas waste-heat.
