Description
Technical field
The utility model relates to a kind of steam exhaust recovering device, belongs to waste heat recovery apparatus, is widely used in the recycling of industrial exhaust steam, can effectively reclaim the exhaust steam of discharging in the industrial processes.
Background technology
At present, a lot of industrial enterprises discharge exhaust steam (these exhaust steam are that water heat absorption vaporization forms) in process of production, and this exhaust steam generally all is direct discharging, so not only can cause white pollution and thermal pollution, but also can cause the waste of water resource and heat energy.Because it is low that the pressure of exhaust steam has height to have, the effect that adopts prior art to reclaim is generally all poor, very is that exhaust steam can not directly be utilized.
In order to eliminate the cavitation problem that the high temperature water pump produces when carrying high-temperature water, on the high temperature water pump anti cavitation device is installed.Anti cavitation device adopts prior art, and its patent No. is ZL93213495.5, and publication number is CN2162550.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of steam exhaust recovering device.
The technical solution of the utility model is that this device comprises fixed gas tapping equipment, spray absorption plant, blended absorbent device, low pressure exhaust steam induction apparatus, water tank, anti cavitation device and high temperature water pump etc.
The fixed gas tapping equipment communicates with atmosphere, the discharging incondensable gas.
On the spray absorption plant, be provided with desalted water import and stainless steel nozzle.Desalted water enters the spray absorption plant, pass through the stainless steel nozzle again after, desalted water all is dispersed into fine liquid particles, is sprayed onto from top to down on the blended absorbent device.
The blended absorbent device constitutes main body by the stainless steel cloth filler.The desalted water that falls from above and the exhaust steam that comes up from below abundant contact heat-exchanging in the blended absorbent device, final most exhaust steam is desalted water and absorbs, minute quantity exhaust steam and incondensable gas upwards enter the spray absorption plant, exhaust steam is all absorbed in the spray absorption plant, and incondensable gas continues upwards to enter atmosphere through the incondensable gas tapping equipment.
Be provided with low pressure exhaust steam import and desalted water import on low pressure exhaust steam induction apparatus, its main body is a venturi nozzle.Desalted water is extracted into the low pressure exhaust steam in the housing below the blended absorbent device by venturi nozzle, and desalted water falls into water tank, and exhaust steam upwards enters the blended absorbent device.
The high pressure exhaust steam enters water tank, and through the abundant mixed heat transfer of desalted water in high pressure exhaust steam distributor and the water tank, most of high pressure exhaust steam is desalted water and absorbs, and the small part exhaust steam upwards enters the blended absorbent device.
After the exhaust steam of middle pressure enters water tank, upwards enter the blended absorbent device.
Desalted water falls into water tank after spraying absorption plant, blended absorbent device.
Desalted water in the water tank enters anti cavitation device and water pump through delivery port.Anti cavitation device is to constitute main body by jet pump, adopts the principle design of spraying supercharging.High-temperature water pump discharge fraction desalted water enters jet pump, desalted water in the water tank is extracted into the inlet of high temperature water pump, the high-temperature water pump intake forms a zone that is higher than tank pressure, the desalted water of high-temperature water pump intake is in undersaturated condition, therefore the high temperature water pump is when carrying the high temperature desalted water, pump entrance steam bubble can not occur, thereby eliminates the high temperature pump cavitation.
At last, desalted water transfers out through the high temperature water pump.
The utility model beneficial effect is in steam exhaust recovering device, adopts corresponding separately recovery part for the exhaust steam of different pressures, reduces the phase mutual interference of different pressures exhaust steam, helps multiple pressure exhaust steam and reclaims simultaneously.Anti cavitation device is installed on the water pump, thoroughly eliminates pump cavitation.Recycle the heat and the water of industrial exhaust steam by steam exhaust recovering device, realize energy-saving and emission-reduction, reduce white pollution.
