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 condensate water of multiple different pressures.
Background technology
The recovery system of existing exhaust steam and condensate water is made up of the connecting pipe between condensation tank or lime set jar, condensate pump and these parts, with the condensate water 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 condensate water of multiple different pressures can be also reclaimed in energy-conserving and environment-protective and reduce the place area occupied simultaneously.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of vapor recovery system, comprise recycling can, the admission jet pump, go out the admission water inlet pipe of water fluidic pump and some different pressures, described admission jet pump is provided with the suction inlet of single pressure or the suction inlet 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 pump of tank body, low pressure admission water inlet pipe in described some admission water inlet pipes connects the suction inlet or low pressure suction inlet (the less suction inlet of absolute pressure in a plurality of suction inlets of admission jet pump of the single pressure of described admission jet pump, down together), high-pressure admission water inlet pipe in described some admission water inlet pipes connects high pressure suction inlet (the bigger suction inlet of pressure in a plurality of suction inlets of admission jet pump of described admission jet pump, down together), or connection recycling can, or connect described admission jet pump high pressure suction inlet and described recycling can respectively, the described suction inlet that goes out water fluidic pump connects described tank body top, the jet import connects described tank body bottom by described draining high-pressure pump, jet exit connects the water pipeline, keeps being enough to make the pressure that is converted into aqueous 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 pump, in recycling can, form high pressure, pressure control by appropriateness, just can make steam be condensed into water not needing further to reduce under the situation of temperature, making the bottom in the recycling can is condensate water, 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 pump, 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; Because the suction inlet by admission jet pump low pressure suction inlet or single pressure is with the pressure differential between the corresponding water inlet pipe (exhaust steam or the water source that condenses), vapour in the low pressure admission water inlet pipe (water) is sucked the admission jet pump, mix and enter by jet exit in the tank body of recycling can with jet, and the high pressure suction inlet of the vapour in the high-pressure admission water inlet pipe (water) by the admission jet pump just can enter jet pump, vapour (water) in the part or all of under certain condition high-pressure admission water inlet 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 pump, 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 enter recycling can as high pressure vapour, also help the inhalation flow that reduces admission jet pump low pressure suction inlet simultaneously, reduce the volume and the energy consumption of admission jet pump; 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 steam discharge pressure, guaranteed that water and the vapour in the recycling can be sent into the water pipeline smoothly.
