CN2459089Y - Water sprayer with multiple diffusing tube - Google Patents

Abstract

The utility model relates to a water sprayer, which is composed of water chambers and a plurality of water nozzles which spray towards mixing chambers and are communicated with the water chambers, wherein, one channel is formed by that one water nozzle and one diffusion spraying tube on the outer part of the mixing chamber are matched together; an entire water sprayer is composed of two or more than two channels. Thereby, efflux loss and power consumption is reduced, and pumping efficiency is improved. The ultimate pressure is increased to-0.098Mpa, and the temperature is lower more than 3 DGE C than that of saturation water temperature. The purposes of the water sprayer are extended, and the utility model not only can be used for compressing gas, mixing gas and liquid, and mixing the liquid and other liquid, but also makes vacuum evaporation and condensation, and vacuum degassing possible. The utility model is conveniently combined into products having various specification and types by one to a plurality of normal water sprayers.

Description

Water jet blower with multiple diffuser ducts

A kind of water ejector is that a kind of rough vacuum obtains equipment and Jet injector.

Existing water ejector has two classes basically: a class is single water spray list diffusing tube, and another kind of is multiinjector list diffusing tube.The former is when rate of air sucked in required is big, and the water spray bore needs very big, and water jet is thick.Cause the air water mass transfer insufficient, water jet kinetic energy can not be fully utilized.Though latter's sub-thread water jet is thinner, require multiple jets must focus on the throat of diffusing tube.The mutual collision that this just will certainly cause multiple jets makes a large amount of losses of kinetic energy of water jet, and this water ejector difficulty of processing is also very big simultaneously.

The purpose of this utility model provides a kind of water jet blower with multiple diffuser ducts, makes the working water jet thinner, and air-water two phase flow has good mass transfer effect, does not produce interference between the multiple jets simultaneously, causes the kinetic energy rejection of water jet.Also be convenient to a kind of to be combined into the product of plurality of specifications model to several standard water spargers.

Water jet blower with multiple diffuser ducts, has the hydroecium 2 that feeds press water, the a plurality of water sprays 3 that are communicated with hydroecium and spray to mixing chamber 4, the mixing chamber wall with taken out the exhaust tube 1 that medium is communicated with, outside mixing chamber, adorn diffusing tube 5, it is characterized in that it is one the tunnel that a water spray 3 and 5 injections of a diffusing tube cooperate, and both are coaxial, whole water ejector is made of two-way and above parallel connection.Can also be at the voltage-stabiliser tube 7 of a connection of each diffusing tube outlet installing.Also can set up rectifier lamp 8 and tail pipe 9 in the water ejector outlet port.

Embodiment:

See Fig. 1, hydroecium 2 is arranged on the top, is connected with outside intake pipe by flange 2.1.Hydroecium is fixed on the mixing chamber 4 with the bolt 2.2 of bottom.Mixing chamber is by up-hole plate 4.1, and orifice plate 4.3 and middle cylinder 4.2 constitute.Cylinder lateral wall is fixed flanged (FLGD) exhaust tube 1.5 water sprays 3 are set are quincunx and are contained on the mixing chamber up-hole plate 4.1 with being evenly distributed, and guarantee that the hydroecium sealing is water-tight.The orifice plate 4.3 of mixing chamber has 5 and is the quincunx distribution hole coaxial with water spray, adorns 5 diffusing tube (see figure 2)s and water spray corresponding matching in the hole.The diffusing tube bottom is established and is had 5 cards 6 with upper and lower orifice plate coaxial aperture, and plane and diffusing tube outlet end are tightly connected on the card, is tightly connected with 5 voltage-stabiliser tubes 7 below the card.The card lower plane can also be installed the convergence type rectifier lamp 8 of a band straight tube, and both are tightly connected.Garden cylindricality tail pipe 9 can be set up in rectifier lamp 8 bottoms, and it is connected with the rectifier lamp orifice plate.The shape of top hydroecium 2 can adopt end socket or cylindrical.Diffusing tube 5 shapes adopt long trunnion cast, and length of throat diameter ratio is greater than 6.Working procedure: press water feeds hydroecium 2 through intake pipe, after in hydroecium, all pressing, form high-speed jet through each water spray, after the quilt that suction is entered by exhaust tube 1 is taken out medium and is mixed in mixing chamber, enter corresponding diffusing tube respectively, mixed flow is discharged the air water mixed flow by after the diffusing tube supercharging through barretter.Be connected with system for the ease of water ejector, do not cause flow losses again simultaneously, can set up rectifier lamp and water seal tail pipe.

Techno-economic effect of the present utility model:

Water ejector is the widely used a kind of low vacuum equipments of the many departments of national economy, simultaneously also Be used for pumping liquid, gas-liquid mixed, heating and gas compression, its outstanding advantages is movement-less part, fortune Row is reliable, and maintenance capacity is few, and its shortcoming is suction on-condensible gas ability, and final vacuum is subjected to working water The restriction of saturation temperature, thereby can not be for evaporation and the degasification of cryogenic liquid. The utility model is owing to adopt With a plurality of anemostats in parallel, so each (operating) water nozzle and anemostat size decreases, water jet is thinner, aqueous vapor The mass transfer area of two phase flow increases, and adding upper tank has good voltage regulation performance etc., therefore obtains to take out preferably Gas efficient and high final vacuum, test show, final vacuum reaches-more than the 0.098Mpa: it is right The saturation water temperature of answering is lower more than 3 ℃ than work water temperature. Expanded thus the use of water ejector, made it Not only be used for gas compression, mixing wastewater with air, liquid liquid mixes, and makes vacuum evaporation, condensation, and vacuum is removed Gas becomes possibility. In addition, the utility model also is convenient to a kind of to be combined into to several standard water injectors The product of plurality of specifications model.
