Description
Technical field
The utility model relates to a kind of silencer, particularly a kind of jet flow composite type steam and hot water silencing apparatus of eliminating noise when being used for steam and directly heating cold water.
Background technique
Model utility " jet-type steam silencer " (publication number: 2097993, open day: disclose the noise elimination technique that a kind of steam directly heats cold water 1992.06.04), it produces steam jet by nozzle, between overlapping, the outer hollow water conservancy diversion of nozzle and nozzle forms runner, cavity between nozzle and the water conservancy diversion running-on forms anechoic room, and low-temperature cold water arrives in the anechoic room by runner under the suction function that steam jet produces and high-temperature steam is mixed finishes heat exchange and eliminate noise.This jet-type acoustic wave filter structure is very simple, but heat exchange amount and sound deadening capacity are limited, is applicable to that relatively small-sized use steam directly heats the immersion heat exchange occasion of cold water.For bathing pool, other carbonated drink direct heat exchange capacities such as relatively large water boiler by steam are big, produce the big immersion heat exchange occasion of noisiness, need improved steam heating silencer.
The model utility content
The purpose of this utility model, a kind of jet flow composite type steam and hot water silencing apparatus will be provided exactly, by improving the structure of nozzle and runner, and adopt compound noise elimination, improve heat exchange amount and sound deadening capacity, improve the noise elimination effect, directly heat the needs of the immersion heat exchange occasion of cold water with dealing with various requirements with steam.Improved in addition steam heating silencer also will have good good antiscale property performance, to improve heat exchange efficiency and to prolong its working life.
For achieving the above object, the utility model is taked following technological scheme: jet flow composite type steam and hot water silencing apparatus comprises nozzle, water conservancy diversion cover, floor, hush tube; Nozzle, water conservancy diversion cover, hush tube are positioned on the same axis; Nozzle inside diameter is taper, and its internal diameter size is shunk to nozzle gradually by steam inlet; On the radial cross section of nozzle inner walls, evenly distribute and be fixedly connected with at least two guide vanes along the nozzle inner walls circumference near the nozzle position; Guide vane is a planar, and each guide vane is a symmetry plane with described radial cross section all, and each guide vane is consistent with the inclination angle that described radial cross section forms, and each guide vane the inner is intersected in described radial cross section center and is fixed as one; The water conservancy diversion cover is the funnel-like taper sheath, and its major part is a water intake, and its microcephaly and hush tube one end are docked and connected and are fixed as one; Fixedly connected and isolate by floor between water conservancy diversion cover inwall and the nozzle outer wall runner is arranged; Hush tube is a cylindrical tube, and the cavity between nozzle and the hush tube outlet forms anechoic room; Be provided with a noise elimination storehouse in the hush tube outlet port, noise elimination storehouse and hush tube are positioned on the same axis, and the hush tube outlet is docked and connected and is fixed as one with noise elimination storehouse one end; The noise elimination storehouse is the cylindrical body of a hollow, is provided with dividing plate in the noise elimination storehouse, and noise elimination storehouse inner chamber is spaced apart plural expansion chamber; Each dividing plate center is equipped with throttle orifice; The noise elimination storehouse the other end is provided with water outlet; From the hush tube outlet, throttle orifice is to water outlet, and the diameter in each hole increases successively, becomes diffusion type; By water intake process water conservancy diversion cover, hush tube, the noise elimination storehouse forms runner to water outlet.
During work, the utility model is dipped in the position of the water container (case, pond, jar etc.) of needs heating near the bottom along the axial direction level, and the nozzle steam inlet is communicated with input steam with the steam input pipe road.Steam is accelerated by nozzle in nozzle and sprays into anechoic room, and the high velocity vapor jet promotes proal while of cold water in the anechoic room and contacts moment with cold water and finish mixed.Vapor condensation becomes water volume to reduce to produce negative pressure, and the cold water in the container quickens to flow into anechoic room by water intake through the water conservancy diversion cover and replenishes under this suction function, proceed to mix with follow-up steam.So steam constantly is condensed into water, so circulation.Near the trend that vapor condensation becomes water volume to change the nozzle is wedge, and the water hammer effect that the steam rapid condensation is caused is decomposed and weakens, and has therefore eliminated noise and vibrations that the mixed process of steam and water produces.Water after the heating enters the noise elimination storehouse at a high speed, because sectional area increases and the flow velocity reduction in the noise elimination storehouse, the noise in the water further is eliminated under the effect of reactive muffling, thereby has reached better noise elimination effect.Water conservancy diversion cover of the present utility model is set to funnel-like, helps increasing the flow of current in the runner, reduces flow resistance; Nozzle is set to the taper of convergent, and steam is quickened in pipe gradually, strengthens the speed of nozzle steam jet; In nozzle, install guide vane additional, make high velocity vapor stream become the multi beam swirling eddy of different amount by single bundle air-flow; These all help improving the mixed speed of carbonated drink, improve heat exchange efficiency, and resistive connection dirt performance also obtains better noise elimination effect.Throttle orifice on the dividing plate of noise elimination storehouse changes traditional orifice restriction at the center of dividing plate large diameter throttle orifice to be set, and helps reducing the resistance of current in the runner, improves the heat transfer rate and has also had better resistive connection dirt performance simultaneously.
The utility model has the heat exchange efficiency height by improvements over the prior art, and it is effective to eliminate the noise, and resistive connection dirt performance is good, the advantage of long service life.Use and field testing through the user, the noise elimination effect reaches the requirement of city regional environment noise NBS, be suitable for the urban and rural residents district, the commerce services industry, organ, school, the bathing pool of industrial and mining enterprise, the steam heating water boiler, various immersion heating occasion uses of directly heating cold water by steam such as steam heated water heater.
