Description
The utility model relates to a kind of vapour---the water direct heat-exchange device, and it is on the prior art basis, the applied fluid mechanics principle, the utilization computer software technology carries out simulated test and a kind of novel vapour-water direct heat-exchange device of designing.
Prior art in the utility model prior art field is: CN2092076U " jet-introduced vapour---the water direct heat-exchange device " and CN2126402U " efficient, energy-conservation, the quick vapour of pipe fitting type---water mixer ".The former has utilized original vapour---the shell and the conical nozzle of water direct heat-exchange device, designed that taper driving nozzle, steam are all arranged net and parts such as current stabilization cone, realized that injection combines with injection, its weak point is a complex structure, and steam pressure and water quality are had certain limitation; The latter takes gas thread to connect single water jet column monoblock type respectively and flange connects two kinds of structures of many water jet columns assembly type, designed simple structure, installation, vapour---water direct heat-exchange device easy to use, its weak point is that heat exchange efficiency is low, noise big, it is strict that steam pressure is required.
Purpose of design of the present utility model just is to design a kind of vapour and water sprays simultaneously, can satisfy efficient, stable, energy-conservation, vapour---the water direct heat-exchange device that noiselessness, especially exhaust steam can be reclaimed of any condition of work.
The utility model has designed structures such as the built up nozzle be made up of steam jet and (operating) water nozzle and current stabilization chamber, counter balance pocket, carbonated drink mixing chamber, noise elimination cavity on the prior art basis.Its operation principle is as follows:
In the shell of sealing, be equipped with the cone jet pipe, the jet pipe internal diameter forms the current stabilization chamber and the nozzle of water; The external diameter of jet pipe forms steam jet.Cold water and steam are entered by the porch respectively, are sprayed by nozzle separately through current stabilization arrangement back.The steam and the water of ejection mix at mixing chamber, and hot water is flowed out by outlet through noise elimination cavity.Because this utility model is taked the two spray modes of carbonated drink, forms a particular structure between built up nozzle and housing.This structure has adapted to vapour---a tangent condition of water exchange, when the cold water with certain pressure passes through nozzle, cold water is depressurized acceleration, under the high speed spin and turbulent diffusion effect of the particle that flows, around it gas there is very strong suction-operated, while steam also is accelerated through nozzle, with rapid, steady, the heat exchange fully of cold water generation of (operating) water nozzle ejection, thereby finishes vapour---water heat exchange purpose.
The utility model compared with prior art, had both various vapour---the strong point of water-to-water heat exchanger, have that heat exchange efficiency height, Modulatory character are good, noiselessness, volume be little, simple in structure, with low cost, adapt to various conditions of work, installation, use, maintenance, advantage such as easy to operate, particularly remarkable to reclaiming exhaust steam energy savings effect, can be widely used in other industry of industry.

Below in conjunction with the description of drawings specific embodiment:
Shown in figure one: outer cover of heat exchanger 1 and jet pipe 4 are processed by cast steel respectively, and jet pipe 4 is connected at cold water inlet flange 2 places with shell 1.The tight fit mode is taked in this connection, when the cold water inlet flange with after cold line is connected, jet pipe 4 is just firmly stable with being connected of shell 1.Shell 1 and jet pipe 4 cooperatively interact, and form cold water current stabilization chamber 3, cold water nozzle 5.Steam current stabilization chamber 7, balance of steam chamber 8, steam jet 9, carbonated drink mixing chamber 10, noise elimination cavity 11.
Shown in figure one, shell 1 is to be processed by cast steel, and cold water inlet flange 2, steam inlet flange 6, hot water outlet flange 12 are directly to process on shell 1.Steam plenum chamber 7 is terraced pyramidal structure, and the ratio of inlet diameter, outlet diameter and length is 1: 1.5: 2.Balance of steam chamber 8 is a spherical structure, and diameter is 2: 1 with steam current stabilization chamber outlet diameter ratio.Vapour-water mixing chamber 10 is a pyramidal structure, and outlet diameter is 1: 1.4 with the inlet diameter ratio.Noise elimination cavity is a pyramidal structure, and inlet diameter, outlet diameter are 1: 2: 3 with the length ratio.Cold water current stabilization chamber 3 is a pyramidal structure, and cold water nozzle 5 is a column structure, between them than being 4: 1.Shell 1 is a circular ring-shaped with jet pipe 4 formed steam jets 9, and its endless belt is 2-5mm.
Shown in figure one, the utility model is through the computer simulation test, and in the position (the cold water nozzle of original technology all designs the vertical place in the steam inlet) that surpasses the steam inlet, jet pipe external diameter and internal diameter of outer cover are formed the steamed mouth the cold water designs of nozzles.Since design like this, the one, steam jet and cold water nozzle are in same direction, and carbonated drink is mixed can be steady; The 2nd, when reaching certain pressure in the cold water nozzle, the cold water of ejection vaporization is moved on same axis and is mixed with steam, makes heat exchange more abundant.Mixed steam water interface is reduced into liquid at noise elimination cavity.The essence of this design is to have strengthened the area of carbonated drink exchange, and fluid is mixed in co-flow, has guaranteed characteristics such as noiseless, applying steam pressure are wide, heat exchanger effectiveness height.
Processing method of the present utility model is: at first distinguish cast casing 1 and jet pipe 4, and then be finish-machined to required size, at last jet pipe 4 and shell 1 are connected on same axis.
Shown in figure three, with double jet type vapour---the water direct heat-exchange device is installed among the system, and cold water inlet flange 2 is communicated with cold water control valve 16, and steam inlet flange 6 is communicated with steam control valve 15, hot water outlet flange 12 be communicated with hot water facility 13.Water pump 17 and water pot 18 also are connected among the system by figure.During use, at first cold water control valve 16 is opened, cold water is transferred to normal working flow, slowly open steam control valve 15 then reposefully and heat, heated hot water flows to 13 li uses of hot water facility.
