Description
Technical field
The present invention relates to a kind of vapor recovery system, mainly can be used for reclaiming simultaneously the exhaust steam and the water of condensation of multiple different pressures.
Background technique
The reclaiming system of existing exhaust steam and water of condensation is made up of the connecting tube between condensation tank or lime set jar, condensate pump and these parts, with the water of condensation and the exhaust steam of hot equipment generation, enter water tank after the secondary flash steam be discharged in the atmosphere formation energy waste.If with the lime set jar of sealing, it is hydrophobic to suppress low pressure, causing can not normal heating, so must take open type to emit way of steam.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of vapor recovery system, this vapor recovery system not only can reduce the loss of heat energy significantly, and the exhaust steam and the water of condensation of multiple different pressures can be also reclaimed in energy-conserving and environment-protective and reduce the place occupation area simultaneously.
The present invention realizes that the technological scheme of above-mentioned purpose is: a kind of vapor recovery system, comprise recycling can, the admission Jet injector, go out the admission intake pipe of water fluidic pump and some different pressures, described admission Jet injector is provided with the suction port of a plurality of different pressures, its jet exit connects described recycling can, the jet import connects the bottom of described tank body by the draining high-pressure service pump of tank body, low pressure admission intake pipe in described some admission intake pipes connects low pressure suction port (the less suction port of absolute pressure in a plurality of suction ports of admission Jet injector of described admission Jet injector, down together), high-pressure admission intake pipe in described some admission intake pipes connects high pressure suction port (the bigger suction port of pressure in a plurality of suction ports of admission Jet injector of described admission Jet injector, down together), or connection recycling can, or connect described admission Jet injector high pressure suction port and described recycling can respectively, the described suction port that goes out water fluidic pump connects described tank body top, the jet import connects described tank body bottom by described draining high-pressure service pump, jet exit connects the water pipeline, keeps being enough to make the pressure that is converted into liquid water to the small part exhaust steam in the described tank body.
The invention has the beneficial effects as follows: owing to high-pressure spray effect by the admission Jet injector, in recycling can, form high pressure, pressure control by appropriateness, just can to make vapor condenses under the situation of temperature be water not needing further to reduce, making the bottom in the recycling can is water of condensation, the steam of top for not condensing, realized that thus exhaust steam is by the conversion of vapour phase state to liquid phase, owing to carry out the conveying of medium by the admission Jet injector, therefore the medium that no matter needs to carry is a steam, water still is that steam water interface can be carried, avoided single medium transport equipment can not adapt to the defective of different fluid state, particularly because inevitably carbonated drink mixing and carbonated drink conversion in the exhaust steam course of conveying, more help simplied system structure, the system that guaranteed can move in all cases; Since by admission Jet injector low pressure suction port with the pressure difference between the corresponding intake pipe (exhaust steam or the water source that condenses), vapour in the low pressure admission intake pipe (water) is sucked the admission Jet injector, mix and enter by jet exit in the tank body of recycling can with jet, and the high pressure suction port of the vapour in the high-pressure admission intake pipe (water) by the admission Jet injector just can enter Jet injector, vapour (water) in the part or all of under certain condition high-pressure admission intake pipe is because of having possessed enough pressure, can also directly insert tank body, do not need just can enter the tank body of recycling can through the admission Jet injector, the condensing that has guaranteed various different pressures thus can both successfully enter recycling can, avoided the adverse effect of high pressure vapour to low pressure vapour, make low pressure vapour to press vapour equally to enter recycling can by image height, also help the inhalation flow that reduces admission Jet injector low pressure suction port simultaneously, reduce the volume and the energy consumption of admission Jet injector; Owing to the steam on recycling can top is sucked out water fluidic pump by going out water fluidic pump, and with together sending into the water pipeline after the mixing of the water jets in the pump, avoided the low phenomenon that steam can't be sent into the water pipeline that causes of delivery of steam pressure, guaranteed that water and the vapour in the recycling can be sent into the water pipeline smoothly.
