Adopting this feed liquor distributor can obviously promote dry type evaporator's heat exchange efficiency, improving the energy efficiency ratio of evaporating temperature and system, the system that reaches moves energy -conserving efficient purpose.
Description
Technical field
The utility model relates to the improvement field of evaporimeter, particularly relates to a kind of feed liquor distributor for dry evaporator.
Background technology
Along with constantly sending out of Refrigeration Technique is opened, more high efficiency evaporimeter is constantly developed out, dry evaporator is substituted by full liquid evaporimeter and falling film evaporator gradually in conventional air-conditioning field, but dry evaporator still has irreplaceable advantage in some Refrigeration & Air-Conditioning field, as in cryogenic freezing field and part air-cooled heat pump unit, the oil return of dry evaporator than full liquid evaporimeter and falling film evaporator more reliable and stable, in addition, require it is not very high occasion in some Energy Efficiency Ratio, dry evaporator has the advantage of relative inexpensiveness, simultaneously, dry evaporator refrigerant charge is few, environmental protection more, therefore, dry evaporator remain at present main flow refrigeration plant consider adopt a kind of scheme, dry evaporator shortcoming is that heat exchange efficiency is low, one of them major reason is the problem of gas-liquid two flow assignment inequalities of cold-producing medium.
How to improve the uniform distribution of cold-producing medium, existing method mainly by gas-liquid mixture mixing chamber mixing after, be assigned in heat exchanger tube by capillary one to one by mixture, realization can distribute by this structure more uniformly, but shortcoming is also more outstanding, pressure drop is excessive, if expansion valve is large not, cause pressure of inspiration(Pi) low on the contrary, reduce heat exchange property, and manufacture complicated, cost is higher.
Utility model content
The purpose of this utility model to provide a kind of feed liquor distributor for dry evaporator, and make its structure simple, easy for installation, can make mixture distributed uniform, cost is low.
For solving the problem, the utility model provides a kind of feed liquor distributor for dry evaporator, comprise flow mixing device and porous plate, described flow mixing device is welded on evaporimeter inlet place, and described porous plate is arranged in the hydroecium of evaporimeter, and porous plate is provided with multiple circular hole, the thickness of described porous plate is 2-3mm, described flow mixing device top closure, both sides are provided with the identical circular hole of multiple size, and the diameter of described circular hole is 3-5mm, and flow mixing device front end is provided with mixed phase import.
Further, the Circularhole diameter of described porous plate is 3-4mm.
Further, the circular hole uneven distribution on described porous plate, top circular hole quantity is more than below circular hole quantity, and the Circularhole diameter on porous plate is identical.
Further, described porous plate is made up of carbon steel or stainless steel, and described flow mixing device is made up of carbon steel or stainless steel.
After adopting such design, the utility model at least has the following advantages:
The utility model is installed on the refrigerant inlet place in dry evaporator hydroecium, by changing to the flow direction of gas-liquid mixture the disturbance caused, refrigerant air-liquid two-phase is fully mixed, and by the guide functions of porous plate, realizes the distributed uniform of cold-producing medium.Experiment proves, uses the utility model that the heat exchange efficiency of dry evaporator can be made obviously to promote, realizes the energy-efficient operation of system, and low cost of manufacture, mounting process is simple, and reliability is high.
Obviously can promote the heat exchange efficiency of dry evaporator, improve the Energy Efficiency Ratio of evaporating temperature and system, reach the object of system cloud gray model efficient energy-saving.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of feed liquor distributor for dry evaporator of the utility model.
Fig. 2 is the top view of the flow mixing device of the utility model feed liquor distributor.
Fig. 3 is the porous plate end view drawing of the utility model feed liquor distributor.
Wherein, 1 is flow mixing device, and 2 is porous plate, and 3 is mixed phase import, and 4 is hydroecium.
Detailed description of the invention
With reference to shown in Fig. 1-3, the utility model provides a kind of feed liquor distributor for dry evaporator, comprise flow mixing device 1 and porous plate 2, described flow mixing device 1 is welded on evaporimeter inlet place, and described porous plate is arranged in the hydroecium 4 of evaporimeter, and porous plate is provided with multiple circular hole, the thickness of described porous plate is 2-3mm, described flow mixing device 1 top closure, both sides are provided with the identical circular hole of multiple size, and the diameter of described circular hole is 3-5mm, and flow mixing device front end is provided with mixed phase import 3.
Preferably, the Circularhole diameter of described porous plate is 3-4mm.
Circular hole uneven distribution on described porous plate 2, bottom circular aperture quantity is more than top circular hole quantity, and the Circularhole diameter on porous plate is identical.Porous plate is made up of carbon steel or stainless steel, and described flow mixing device 1 is made up of carbon steel or stainless steel.
Porous plate 2 can be made up of carbon steel or stainless steel, and flow mixing device also can be made up of carbon steel or stainless steel.
Gas-liquid mixture enters flow mixing device from mixed phase import, because flow mixing device one end is closed, mist flows out from radial aperture direction, clash into the hydroecium baffle plate of top and the hydroecium bobbin carriage of below, mix further, then entered the heat exchanger tube of evaporimeter by porous plate, because gas focuses mostly on relatively on top, therefore the below perforate of porous plate is comparatively sparse, and top perforate is more, and object is the liquid inlet volume ensureing each heat exchanger tube.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
