Abstract
A kind of negative-pressure cyclic formula heat recovery unit, the heat exchanger that has an internal insulation two media, heat exchanger one side arranges the import of air compressor medium, the air compressor media outlet that is communicated with heat release medium, heat exchanger opposite side arranges heat exchange import and the heat exchange outlet that is communicated with heat-absorbing medium, and heat exchange import connects the feed tank of in-built soft water by pipeline; Separately have a water tank to be heated, water tank to be heated connects the self-loopa pipeline with recycle pump by the water sucking mouth on it, backwater mouth, is communicated with a manifold on the return pipe of this self-loopa pipeline, and this manifold connects the heat exchange outlet of heat exchanger.Low-temperature receiver in heat exchanger of the present utility model adopts softened water, so non-scaling in heat exchanger has extended working life of equipment, has reduced the later maintenance of enterprise to equipment.
Description
Technical field
The utility model relates to a kind of negative-pressure cyclic formula heat recovery unit, the heat recovery producing for air compressor.
Background technique
Pneumatics unit is in running, and nearly 80% electric energy conversion is heat energy, and this part heat energy is mainly present in the lubricant oil and pressurized air in air compressor.For compressor, the lubricating oil temperature of inlet is too high, can reduce its working efficiency, causes compressor gas production to reduce.In order to guarantee the working efficiency of compressor, air compressor need be equipped with corresponding cooling measure.Air-cooled type air compressor adopt cooling fan by dissipation of heat in atmosphere, water-cooled air compressor adopt cooling tower by dissipation of heat in atmosphere.If this partial heat energy is recycled, can be brought very large energy-saving benefit for enterprise.By the end of at present, the domestic recovery operation that has had a lot of producers to be engaged in residual heat of air compressor, but because the local water quality of most domestic is bad, causes the heat transmission equipment will fouling in the short time, enterprise's later maintenance cost investment increases greatly, has affected applying of heat transmission equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of negative-pressure cyclic formula heat recovery unit, and while solving heat of compressor recovery heating water, the problem of easy fouling, makes cost of investment lower, better effects if.
The purpose of this utility model realizes as follows: the heat exchanger that has an internal insulation two media, heat exchanger one side arranges the import of air compressor medium, the air compressor media outlet that is communicated with heat release medium, heat exchanger opposite side arranges heat exchange import and the heat exchange outlet that is communicated with heat-absorbing medium, and heat exchange import connects the feed tank of in-built soft water by pipeline; Separately have a water tank to be heated, water tank to be heated connects the self-loopa pipeline with recycle pump by the water sucking mouth on it, backwater mouth, is communicated with a manifold on the return pipe of this self-loopa pipeline, and this manifold connects the heat exchange outlet of heat exchanger.Air compressor medium contains oil, G&W, and the high temperature media of air compressor enters heat exchanger by the import of air compressor medium, by air compressor media outlet, flows out.In water tank to be heated, be marked with water to be heated, under the effect of recycle pump, self-loopa pipeline returns to water tank to be heated through backwater mouth from the water suction of water tank to be heated water sucking mouth again after pipeline circulation, due to the jet-action of current, forms negative pressure at manifold place; Softened water is housed in feed tank, and under Manifold pressure effect, in feed tank, low temperature softening water enters heat exchanger, after absorbing compressor oil gas mixture heat, form Low Temperature Steam, enter water tank to be heated, steam and circulating water direct heat transfer in water tank to be heated, form high-temperature-hot-water.
On the pipeline of heat exchange import connection feed tank, electric control valve is set, to facilitate adjusting inflow.
On water tank self-loopa pipeline to be heated, before recycle pump, install safety check, prevent that circulating water from flowing backwards.
On water tank self-loopa pipeline to be heated in recycle pump rear portion, safety check anterior device has butterfly valve.
Low-temperature receiver in heat exchanger of the present utility model adopts softened water, so non-scaling in heat exchanger has extended working life of equipment, has reduced the later maintenance of enterprise to equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the heat exchanger 3 that has an internal insulation two media, heat exchanger 3 one sides arrange air compressor medium import 1, the air compressor media outlet 2 that is communicated with heat release medium, heat exchanger 3 opposite sides arrange heat exchange import and the heat exchange outlet that is communicated with heat-absorbing medium, and heat exchange import connects the feed tank 4 of in-built soft water by the pipeline with electric control valve 5, separately there is a water tank 11 to be heated, water tank 11 to be heated is by the water sucking mouth on it, backwater mouth connects self-loopa pipeline, slip joint 9 by both sides on self-loopa pipeline connects recycle pump 8, on self-loopa pipeline in the anterior device safety check 7 of slip joint 9 above, butterfly valve 10, butterfly valve 10 is also set on self-loopa pipeline after recycle pump 8 rear portion slip joints 9, the effect of slip joint 9 is to be convenient to install recycle pump 8, the object of butterfly valve 10 is be convenient to turn-off pipeline with maintenance or change recycle pump 8, on the return pipe of this self-loopa pipeline, be communicated with a manifold, this manifold connects the heat exchange outlet of heat exchanger 3, position near heat exchange outlet on manifold arranges visor 6, be convenient to observe heat exchange operation conditions.When system is just moved, the interior injection soft water of feed tank 4, the interior injection tap water of water tank 11 to be heated, the tap water that recycle pump 8 extracts in water tank 11 to be heated, tap water is back to water tank 11 to be heated more afterwards, utilize the ejecting force of recycle pump 8 self to make to form negative pressure between the manifold on heat exchanger 3 and recycle pump 8 export pipelines, by electric control valve 5, regulate the interior appropriate softened water of feed tank 4 to enter heat exchanger 3, after the heat of softened water absorption air compressor high temperature media, from liquid state, become gaseous state, enter afterwards water tank 11 to be heated, direct and tap water mixed heat transfer forms hot water, supply with enterprise staff bathing or heating use.
