Beneficial effect of the present invention is: enter the water under high pressure on top, power drive room from water under high pressure or other liquid pressure fluid inlets through all pressures in the upper space of power drive room, substantially identical pressure is formed at the entrance point of each playpipe, water or other fluid liquids be ejection at a high speed after playpipe, at the indoor formation jet of jet mixing, the gaseous material connecting steam or other gaseous material imports is sucked, and constantly steam or other gaseous materials are entrainmented in jet in flow process, discharge heat energy and then be converted to liquid state after steam or other gaseous materials contact with water or other fluid liquids, become a part for the liquid in jet, finally discharge in liquid form from the lower of increaser or rear port, due to adding of steam or other gaseous fluids, the water of discharging from increaser or the amount of other fluid liquids are more than the amount of the water sent into from water under high pressure or other liquid pressure fluid hoses or other other fluid liquids of fluid liquid, additional part is exactly reclaimed steam or other gaseous materials, the steam emitted originally utilizing or other gaseous materials become can by the water that conveniently utilizes or other fluid liquids of other fluid liquids, achieve the recovery of water or other fluid resources in steam or other gaseous materials, because power drive room and jet mixing room all adopt vertical or level, its power drive room and jet mixing room are up and down or horizontal distribution, axis is positioned on same horizontal or vertical straight line, compared with power drive room and the upper and lower vertical distribution in jet mixing room distribute with horizontal linear, vertical distribution more reasonable, because power drive room and jet mixing room distribute up and down, axis is positioned on same vertical line, the potential energy of water or other fluid liquids can be made full use of thus, water or other fluid liquids its potential energy in process that flows downward under gravity is constantly converted to kinetic energy, be conducive to significantly reducing power consumption and improving mixed effect, due to water under high pressure or other liquid pressure fluids enter power drive room after the cross-section of river enlarge markedly, play and well all press effect, make the pressure of each playpipe substantially identical, be conducive to the optimization realizing jet tissue, improve the suction capactity of steam or other gaseous materials and entrainment ability, owing to have employed some playpipes, form the boundling shape jet of cylindricality or taper, make the suction capactity of steam or other gaseous materials and entrainment ability all much larger than the single jet of same flow, lessly in other words to conflict because boundling shape jet and the undergauge mode of reducing pipe are basically identical, be not only conducive to the speed continuing to increase jet, but also be conducive to the resistance that reduces because undergauge brings, be conducive to reducing power consumption, owing to being provided with the increaser after trunnion and trunnion, the mixing forming high strength at trunnion place is impacted and obtains sufficient heat exchange and condensation time at increaser, even if ensure that thus under the condition of rather harsh, also can realize the abundant mixing of steam or other gaseous materials and water or other fluid liquids and make steam or other gaseous materials all become liquid water or other fluid liquids.Because gas-liquid retracting device of the present invention have employed liquid air mixer of the present invention, only need with water under high pressure or other liquid pressure fluids for power, and apply certain recirculated water or other fluid liquids before system starts, in running, the liquid of steam or the conversion of other gaseous materials constantly enters in recirculated water or other fluid liquids, thus without the need to circulatory system moisturizing or other fluid liquids, greatly facilitate operation thus.During condition existence restriction, power drive room and jet mixing room also can distribute by horizontal linear at the scene, and power consumption at this moment increases relatively, and principle is identical with vertical distribution.
Structure of the present invention is simple, easy to operate, the steam that can process or the amount of other gaseous materials large, not only be adapted to the recovery of industrial exhaust steam or other gaseous materials, but also be adapted to Steam Recovery in boiler of power plant flue gas, steam in industrial furnace and various tower class tail gas or the recovery of other gaseous materials, the water reclaimed or other fluid liquids directly or can be back to production system after certain purified treatment, can not only be conducive to thus saving operating cost, but also the consumption of the water resource or other liquid fluids that can reduce production system is in a large number even without the need to consumption of new water or other fluid liquids.
Detailed description of the invention
See Fig. 1 and Fig. 2, the liquid air mixer 100 that the present invention relates to is primarily of interconnective power drive room 120 and jet mixing room composition, described power drive room and jet mixing room are vertical or horizontal, described power drive room is positioned at the top (vertical) of described jet mixing room or front end (horizontal etc.), the dividing plate 131 of described power drive room and jet mixing room is provided with in described liquid air mixer, described dividing plate is provided with some playpipes 132, such as can fix welding or from upper, below or from a left side, right clamp nut is fastening, the entrance point of described playpipe is positioned at described power drive indoor, it is indoor that the port of export is positioned at described jet mixing.
Preferably, the pattern of each playpipe is preferably the form of basic indiffusion or less diffusion, to make these little jet beams 141 accumulate the diminishing taper large stream in water cross section, to be adapted to the caliber change being positioned at reducing pipe below described jet mixing room, and, test display, under the occasion that the present invention adapts to, the diffusion of jet crosses the soakage that senior general obviously reduces steam or other gaseous materials.
Such as, preferably, the pore of described playpipe (or it sprays water outlet or other fluid liquid parts) is isometrical circular hole, port of export end face is that (namely its port of export end face and the intersection of the arbitrary plane crossing playpipe axis are that middle part (refers to the axis direction of playpipe here) vertically to the arc of injection direction projection for the arc surfaced of center projections, the arc of this projection is preferably semicircle or half elliptic, the little jet beam that the playpipe of this structure ejects is for a fluid stream that the port of export (nozzle) of other shapes sprays, diffusion obviously reduces, can produce in longer path thus and better entrainment effect, and be obviously conducive to the resistance reducing reducing pipe.The playpipe of some this structures is relied on to form boundling shape jet tissue, the steam that can suck or the flow of other gaseous materials adopt the equipment of jet suction apparently higher than Venturi tube and other, allow to be inhaled into rate-of flow to change in a wider context, in addition, adjusted design disposal ability can also be carried out by parameters such as the playpipe of selection suitable number and the power drive room calibers matched, as in the flue gas vapors discharge size range of existing boiler of power plant, when not changing playpipe size and other relative configurations, disposal ability is directly proportional substantially to the quantity of playpipe.
