The liquid air mixer 100 that the utility model 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 top or the left and right of described jet mixing room, the dividing plate 131 of jet mixing room liquid air mixer being divided into upper or anterior power drive room and lower or rear portion 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 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 applicable to be positioned at below described jet mixing room or the change of rear reducing pipe caliber, and, test display, under the occasion that the utility model 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 ejects fluid section) 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 pipe calibers matched, in the steam of the flue gas etc. of existing chemical plant installations emission or the industrial furnace tail gas such as metallurgical or boiler of power plant or the discharge size range of tail gas or flue gas, when not changing playpipe size and other relative configurations, disposal ability is directly proportional substantially to the quantity of playpipe.
Described jet mixing pipe by from up to down or from left to right or the reducing pipe 140, trunnion 150 and the increaser 160 that connect successively such as right-to-left form, be similar to Venturi tube structure, but suction inlet is not set at trunnion place, but steam or other gaseous material suction inlets are set on top, jet mixing room or front end, the steam of suction and water jets or other gaseous materials and other fluid liquids are together sent into jet mixing pipe (also often having had mixing to a certain degree before entering jet mixing pipe).Overcome the defect that Venturi tube soakage is little thus, make treating capacity by selecting the power drive pipe caliber, playpipe quantity and other design parameters that adapt to, the processing requirements of the chemical plant installations of the existing any specification of China, industrial furnace, coal burning power boiler etc. can be met, on the other hand, because jet water and steam or other fluid liquids of jet together enter jet mixing pipe with other gaseous materials, just mixing from reducing pipe, substantially prolongs mixed path thus, the reducing pipe that originally there is not mixing in Venturi tube is made to have possessed immixture, because little jet beams some in reducing pipe exist certain impact and collision in the process flowed and spread, also because the caliber of reducing pipe reduces gradually, velocity of medium is accelerated gradually, make reducing pipe can have very strong immixture, make the abundant mixing that water and steam or other fluid liquids and other gaseous materials just realize or substantially achieve on material in trunnion, significantly can shorten the length of increaser thus, reduce volume and save manufacturing cost.
