Description

The dicyclic sparger

Technical field

The invention belongs to a kind of fluid pump, relate to the sparger that a kind of fluid-mixing is used, specifically a kind of dicyclic sparger that is used for the fluid-mixing injection.

Background technique

Sparger is also claimed Jet injector, and it is with the inferior fluid of higher pressure main fluid injection low pressure (or not having pressure), accomplishes main fluid suction time fluid and carries out the device that mixed flow is carried.Because sparger does not have moving parts, use reliably, be widely used on the fluid device in multiple field.

Existing sparger is made up of primary fluid inlet pipe, main fluid nozzle, inferior fluid input, mixing chamber, mixing tube or mixing diffuser pipe; The inferior fluid of feeding mixing chamber is pumped into mixing tube through nozzle and the periphery that shrinks the awl mouth by the primary fluid jetstream by the ejection of main fluid nozzle, in mixing diffuser pipe, mixes all pressure output.The mixing tube of this sparger generally is single elongated pipe, like typical Venturi tube.

Publication number is that the British Patent Application of WO2006/010949 discloses a kind of sparger of being located at the annulus nozzle of mixing tube periphery; This circular cone jet of annulus nozzle that utilizes has strengthened surface of contact and the injection suction capactity of main fluid to inferior fluid, has strengthened mixing and the heat and mass efficient of sparger to master/inferior fluid to a certain extent..The patent No. is that to provide a kind of be the annular jet formula vacuum pump of working medium with water to the Chinese utility model patent of ZL 02223851.4.Between its sucking pipe group and the injection pipe assembly annular slot spout is arranged.Make gas brought into liquid acceleration and the compression of trunnion, realize vacuumizing purpose through high-speed motion by liquid jet.Also have some porous and the sparger of some other profiled holes nozzle or the sparger of multistage polyphone in the practicality, but they do not change the agent structure that a sparger uses a single pipe yet.The basic structure of this single-tube injector is leveraged to the present and does not become.The advantage of single-tube injector be simple in structure, working stability is reliable, but has following shortcoming:

1. existing sparger mainly leans on the turbulent fluctuation diffusion of jet in mixing the pipe range stroke; Make main fluid and time mutual blending of fluid; The turbulent fluctuation diffusion of jet needs a process that in mixing tube, produces development and strengthen; Thereby sparger all must need elongated mixing tube (or mixing diffuser pipe); And big flow sparger needs the heavy caliber mixing tube, and it is more difficult that bore leans on the jet turbulent fluctuation to diffuse to form even mixing more greatly, can in mixing tube, all press fully by the blending mass transfer for making main fluid and the inferior fluid that quilt is entrainmented; Just the length of mixing tube be need increase greatly, thereby the existing especially big specification single-tube injector of ejector axial dimension, space occupy-place and the excessive shortcoming of weight caused.This is concerning needs small volume and underloaded many occasions, and it installs and uses very unfavorable.

2. single-tube injector or the Jet injector to stimulating the menstrual flow more greatly with flow; Mixing tube need stimulate the menstrual flow greatly; Well take out the purpose (promptly reaching big injection ratio or higher mixing output pressure) of drawing time fluid for reaching; The larynx face that needs to keep certain is full of mixing tube than (mixing tube and main fluid nozzle exit ratio) so that the main fluid free jet can spread after arriving certain aperture; Cause the piston swabbing effect. to stimulating the menstrual flow more greatly and the essential power stream of wanting larger-diameter nozzle exit and big footpath bundle of the single-tube injector of flow, but primary fluid jetstream is positioned at mixing chamber central authorities, and inferior fluid is entrainmented at primary fluid jetstream bundle periphery; The primary fluid jetstream diameter is bigger just means the contact rate of main fluid and time fluid of per unit volume with to entrainment efficient low more, and promptly mass ratio of induced-to-inducing air or injection compare step-down.For improving jet pump efficient, the prior art solution is to make jet be divided into several strands promptly to adopt the multiinjector jet, but this does not change primary fluid jetstream at central injection periphery time fluid distribution state.Because stream thigh or peripheral jet beam blocks on every side; Inferior fluid on every side is difficult to be drawn into the inner area of central jet; Entrainment still and mainly carry out in the mixing chamber outer periphery; This will inevitably reduce the ability (both injection than) of main fluid suction time fluid, thereby those are required suctions time fluids as much as possible is most of sparger of purpose, and their injection efficient is low to be main shortcoming.

3. existing sparger only has a cover main fluid (working fluid) to the injection of inferior fluid and the channel design of mixing; So only can realize of all pressure mixing of a kind of main fluid to a kind of fluid; Cause its function simple; Can not realize the demand of a kind of main fluid some occasions that injection blending are simultaneously all pressed to two kinds of time fluids, Applicable scope is limited.

Said center mixing tube outlet end is longer than said annular mixing chamber outlet end in the axial direction slightly; The ring nozzle is many same oblique skewed slots that are uniformly distributed with of taper ringwise in said; Said outer shroud nozzle is a plurality of with oblique skewed slot or a plurality of with oblique hole for what on the outer shroud nozzle carrier, be uniformly distributed with, and the rotation direction of each skewed slot of said interior ring nozzle and each skewed slot of said outer shroud nozzle or inclined hole is opposite.Because both rotation directions of spraying of inner and outer rings nozzle are opposite; Two bursts of reverse mixed flows that make the output of center mixing tube and annular mixing tube are in powerful mutually friction of total mixing chamber and disturbance; This also can improve the heat and mass speed of dicyclo injector of the present invention, and reduces injector whole axial dimension and weight.

When main fluid is water, wet goods liquid, and inferior fluid is when being gas, said in ring nozzle or said outer shroud nozzle be liquid spray nozzle; In said the ring nozzle be said central authorities time fluid inlet cover rear end the outlet tapering with said between the pipe conical entrance hole to pressing from both sides many strias or the microgroove that is uniformly distributed with on the looping conical surface of gap; Said outer shroud nozzle is that the spray orifice that is uniformly distributed with is in the form of a ring established eddy current or swirling flow atomizing core in it, or said outer shroud nozzle is that its jet flow can produce the pore that is uniformly distributed with in the form of a ring, groove, the seam of bump atomizing mutually.Inner and outer nozzle is a spray nozzle with spray function, make the primary and secondary fluids to mix more from the confluence of the initial uniform closely, and contribute to the mainstream body for the secondary fluid adhesion and portable, it can significantly improve The present invention ejector heat and mass transfer rates, and increased dust ejector, rapid evaporation, condensation and other specific functions quickly.

The leading portion of said total mixing output tube is provided with the two-stage injection device, and this two-stage injection device is made up of the outlet of the total mixing chamber on the said outer tube or the secondary outer shroud nozzle of total mixing tube leading portion outlet concentric peripheral with it and the extension tube of periphery pipe; The anterior big footpath sleeve pipe of this periphery pipe is fixed on around the outer wall of this total mixing chamber outlet pipeline section or total mixing tube leading portion, forms the second main fluid annular chamber of sealing between the two; Should establish the second main fluid inlet duct on the sleeve pipe sidewall of big footpath; The gap that between the male cone (strobilus masculinus) of the outer pipe of the contraction taper hole mouth of this big footpath sleeve pipe and this total mixing chamber outlet pipe or total mixing tube leading portion, forms constitutes secondary outer shroud nozzle; The extension tube of this periphery pipe is with below secondary outer shroud jet expansion and is shunk the inner chamber formation secondary mixing chamber that awl exports, and this secondary mixing chamber outlet is level and smooth to be communicated with the straight tube at total mixing output tube rear portion or always to mix the straight-through more total output tube rear portion flaring diffuser pipe directly that mixes of straight tube that output tube enters the mouth; This pair outer shroud nozzle is circular cone slit or many straight troughs that on circular cone, are uniformly distributed with or skewed slot; The cone angle of this circular cone is less than 90 °, and cone angle is towards total mixing output tube outlet end.

Import the outlet mixed flow of the total mixing chamber of the second main fluid injection or total mixing tube by secondary outer shroud nozzle, and mix once more with it and to make it to boost; Can quicken effectively or strengthen to mix and stir.If the second main fluid inlet duct connects different primary fluid source respectively with original main fluid inlet duct, also can enlarge the scope of dicyclo ejector applications of the present invention, make it to become multithread body injector mixer with different pressures and phase.

Existing single mixing tube sparger; The main fluid nozzle is located at mixing chamber central authorities; Utilize the piston effect of main fluid, and the inferior fluid that the friction viscous force between main, inferior fluid is entrainmented around the mixing chamber gets into mixing tube jointly, during the especially big latus rectum of this kind sparger to the mixing tube jet; The mixed efficient of the ginseng of its injection rate and mixing tube is lower; Need could produce through long mixing tube and enough breathe heavily stream primary-to-secondary flow is fully mixed, after dicyclo sparger of the present invention mixed big latus rectum single tube the center mixing tube that becomes less latus rectum and annular mixing tube and mixes separately, mixing again superposeed; Become the dicyclo sparger that two annular ejector parallel connections were nested with and had common output tube to single sparger, can improve injection rate and mixing efficiency.Because inside and outside two mixing tube cross section diameters and aspect ratio are less relatively with the single-tube injector latus rectum of flow; This helps the piston effect of reinforced suction; Because the outlet velocity pressure gap of inside and outside two mixing tube mixed flows; Can cause the mutual injection and the secondary mixed function of inside and outside two strands of fluid-mixings, efficiently solve the existing inefficient problem of sparger injection, and the inside and outside mixing tube latus rectum of inside and outside two annular ejectors all can be less; The length weight and the size of total mixing output tube are significantly reduced, but injection efficient heighten.Because the brute force of effluenting of inside and outside two mixing tubes of dicyclo sparger of the present invention is collided and mix in the whirlpool; Therefore; The comparable existing single-tube injector of dicyclo sparger of the present invention only depends on central jet freely to spread to reach the injection effect of attaching the wall suction to get well, and fluid resistance is less, can significantly improve time fluid by the amount of main fluid injection ratio; Can also comprehensively shorten the length of mixing tube, especially it can also improve its working efficiency and improve cost performance when reduce sparger length overall and weight.

The main fluid of the present invention's input can volley with a kind of fluid or two kinds of different inferior fluids through inside and outside two annular ejectors, exports the fluid-mixing of all pressing then.Main fluid can be gas, liquid or the gas-liquid mixed flow body of elevated pressures, and inferior fluid can be lower or stress-free gas of pressure or liquid, or heterogeneous fluid-mixings such as gas-liquid mist and flue dust.Therefore the 26S Proteasome Structure and Function of dicyclic sparger of the present invention is comparatively various.This shows that dicyclo sparger of the present invention can effectively overcome the shortcoming of existing single-tube injector.Axial dimension and weight greatly reduce, and significantly strengthen through the ability with process fluid, and performance is good during big flow work, applicable to the big flow of need place, the water route air transportation means of strict restriction etc. are arranged like engineering such as the energy, environmental protection or to dimensional weight.Outstanding advantage and beneficial effects such as having economical with materials, save the space, save energy, improve work efficiency, use is wider.
