Description
The utility model is a kind of novel steam jet ejector, is that a kind of rough vacuum obtains and gas compressing equipment.
Existing steam jet ejector has two kinds of patterns basically: a kind of is that a nozzle is to a diffuser pipe; Another kind is that a plurality of nozzles are to a diffuser pipe.The latter is used in the main equipment more.After the discharge pressure of sparger is greater than 50mba, condenser need be set to alleviate the load of back level sparger.According to the steam jet ejector theory, the factor that influences ejector efficiency mainly contains following several respects: the compression ratio of (1) sparger, promptly discharge pressure and the ratio that sucks pressure.Compression ratio is big more, and pumping efficiency is low more, otherwise too.In other words, after suction pressure was given, the high more injection efficient of discharge pressure was low more, and discharge pressure is low more, and injection efficient is high more.This shows that reducing discharge pressure (being back pressure) is one of key that improves injection efficient.Reduce to discharge pressure two kinds of methods are arranged: a kind of is that front-mounted pump is set, and another kind is to establish condenser to make general vapour condensation behind diffusion.(2) position and the Mach number of the pneumatic shock wave of control.Gas ejector is to utilize the superonic flow nozzzle intake-gas, with the principle of supersonic diffuser by pressure rise across shock envelope mixed gas is discharged under the design back pressure.Position and the Mach number of shock wave in Diffuser greatly has influence on ejector efficiency and working stability.Theoretical experiment points out that when shock wave was in Diffuser venturi and venturi Mach 2 ship 1, sparger had peak efficiency.Fluid mechanics is an experiment section, can not rely on theoretical calculation to guarantee design parameter fully, and this will lean on scientific experiment.Yet requiring of user is different, and specifications and models are of all kinds, in fact can not carry out a large amount of like this experiments.Best bet is that several specifications of design experiment are optimum injector, is combined into the product of different model specification then with it.(3) pressure of working steam and quality: the working steam degree of superheat is suitable, and the high more ejector efficiency of vapor pressure is high more.Yet too high vapor pressure is uneconomic to the user in fact, according to the common vapor pressure of user's understanding about 0.4-0.6Mpa.The working steam pressure of 0.2-0.3Mpa then has bigger market.Therefore must reduce working steam pressure, so that obtain bigger market.The approach that reduces working steam pressure has two: one is the back pressure that reduces sparger.Another is the pressure loss of avoiding working steam, and in other words, design vapor storing chamber reduces flow losses and makes stagnation pressure stable.(4) vapour one gas mass transfer area: because the convolution effect of jet is to only occur in the boundary layer, therefore imitate the giant that many small nozzles replace equal flow, will obtain bigger pumping efficiency with quantity.
The purpose of this utility model provides a kind of novel steam jet ejector, overcome the shortcoming of existing sparger, and according to the basic theories of above-mentioned steam jet ejector and influence the factor of efficient, utilize the compact injector of optimizing, be combined into the sparger of various models, and itself and water ejector combined together, further improve the efficient of steam jet ejector, thereby enlarge its use and market share.
A kind of novel steam jet ejector has the steam chest 2 that feeds working medium, be communicated with steam chest and to the air-blast atomizer 3 that sprays of mixing chamber 4, the mixing chamber wall is established and is taken out the exhaust tube 1 that medium is communicated with, mixing chamber peripheral hardware diffuser pipe 5, it is characterized in that it is one the tunnel that an air- blast atomizer 3 and 5 injections of a diffusing tube cooperate, and both are coaxial, whole sparger is provided with two-way and above formation in parallel, at the outside installing of diffuser pipe outlet section cooling water chamber 6, its outside is equipped with and (is contained one) more than one and be communicated with cooling water chamber and place water spray 7 in the rectifier lamp 8, and both constitute a water sprayer.
