Description

Diffuser pipe and the evaporative condenser including it
Technical field
The utility model is related to a kind of diffuser pipe, more particularly to a kind of evaporative condenser diffuser pipe and including this The evaporative condenser of diffuser pipe.
Background technology
Since in the 1980s, introducing evaporative condenser China, it is big that evaporative condenser is mainly used in freezer Type ammonia refrigeration system, in other field using less.Over nearly 30 years, with the exploitation of evaporative condenser technology, various new evaporations Formula condensable product comes out, and evaporative condenser there occurs very big change in structure, on heat exchange efficiency other relative water coolings and Air-cooled condenser there has also been certain advantage, evaporative condenser series of products be gradually applied to central air-conditioning, pharmacy, chemical industry, All conglomeraties such as oil.For other cooling devices, limitation and China's water resource due to geographical position lack, and steam at present The ratio that hairdo condenser apparatus is accounted in the application is not very high, focuses primarily upon coastal area, but its high efficient heat exchanging Feature, makes evaporative condenser have very good application prospect.
Because there is heat and mass, the heat exchange efficiency of evaporative condenser is higher than general condenser.Influence is steamed One of principal element of heat exchange efficiency of hairdo condenser is the air velocity by evaporative condenser, i.e., cold by vaporation-type The air quantity of condenser.
At present, the solution for improving air quantity is to improve the rotating speed of blower fan, and after the rotating speed for improving blower fan is directly brought Fruit is that energy consumption is significantly increased, therefore, and how to improve air quantity without energy consumption is significantly increased is always to perplex the difficult point of enterprise.
Utility model content
The problem of the utility model exists for prior art and not enough there is provided a kind of new diffuser pipe and including it Evaporative condenser.
The utility model is to solve above-mentioned technical problem by following technical proposals:
The utility model provides a kind of diffuser pipe, and its feature is, the diffuser pipe is cone, and the import of the diffuser pipe is straight Footpath is D1, and the outlet diameter of the diffuser pipe is D2, and the height of the diffuser pipe is H, and outlet diameter D2 is more than inlet diameter D1;
Wherein, H and D2 and D1 relation is:H=a* (D2-D1)/2, a is coefficient.
It is preferred that inlet diameter D1 numerical value is identical with the diameter of the air outlet of the blower fan of an evaporative condenser.
It is preferred that inlet diameter D1 value is 1200mm, outlet diameter D2 value is 1500mm, height H Value be 1160mm.
It is preferred that coefficient a span is 6-10.
The utility model also provides a kind of evaporative condenser, and its feature is, it includes a blower fan and an above-mentioned expansion Pressure pipe, the diffuser pipe is installed at the air outlet of the blower fan.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, produce the utility model it is each compared with Good example.
Positive effect of the present utility model is:
The evaporative condenser of the present utility model for being provided with diffuser pipe, the evaporative condenser with being fitted without diffuser pipe Compare, air quantity can be greatly improved;Compared with changing mode of the rotating speed to improve air quantity, power consumption can be greatly lowered.This practicality New diffuser pipe production and install simple, and install diffuser pipe evaporative condenser energy-saving effect significantly, can push away Wide application.
Brief description of the drawings
Fig. 1 is the structural representation of the diffuser pipe of the utility model preferred embodiment.
Fig. 2 is the structural representation of the evaporative condenser for being provided with diffuser pipe of the utility model preferred embodiment.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made all belongs to The scope protected in the utility model.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of evaporative condenser, and it includes a diffuser pipe 1 (see Fig. 1) and one Blower fan 2, the diffuser pipe 1 is installed on the air outlet of the blower fan 2.
The diffuser pipe 1 is cone, and the inlet diameter of the diffuser pipe 1 is D1, and the outlet diameter of the diffuser pipe 1 is D2, should The height of diffuser pipe 1 is H, and outlet diameter D2 is more than inlet diameter D1.
Wherein, H and D1 and D2 relation is:H=a* (D2-D1)/2, a is coefficient, and coefficient a span is 6-10, Inlet diameter D1 numerical value is identical with the air outlet of the blower fan 2.
Inlet diameter D1 value is 1200mm, and outlet diameter D2 value is 1500mm, and height H value is 1160mm。
The effect after diffuser pipe installation in order to verify evaporative condenser, the steaming to being fitted without and being mounted with diffuser pipe Hairdo condenser is tested contrast.
1st, the instrument and test method that test is used
(1) air-quantity measuring:Use ZRQF types heat bulb (ZRQF be using measure wind speed as basic function and by wind-warm syndrome, Relative humidity measurement function is combined and one instrument), it is each on 9 fixing points in the vertical horizontal air intake surface of air intake surface and tower top Tested.
(2) air stagnation pressure value is surveyed in the air chamber of blower fan suction inlet bottom, measuring instrumentss are to use the stagnation pressure with kuppe Probe (handing over big manufacture) and the YAMA MOTO W0-80 pressure difference meters of Japan's production.
2nd, test result
The total blast volume for being fitted without diffuser pipe is G'=56284m3/h;It is G=to install the total blast volume after diffuser pipe 69844m3/h。
The ratio that air quantity is improved is (G-G')/G=(69844-56284)/69844=24.1%.
3rd, validation test
Using in the air chamber of tower, air stagnation pressure value is measured, measures and is fitted without the stagnation pressure value of diffuser pipe for 78.48Pa, It is 117.72Pa to install stagnation pressure value after diffuser pipe.
According to Bernoulli equation, the absolute value of stagnation pressure value is directly proportional to air quantity square in air chamber, therefore installs diffuser pipe with not having Have and the flow ratio of diffuser pipe is installed for (117.72/78.48) 1/2=1.51/2=1.225.This numerical value is measured with anemobiagraph The ratio between flow 1.241 compared to closely.
4th, the test and analysis of power input to machine
It is 7.547kW to be fitted without electrical power after the evaporative condenser of diffuser pipe, test;The vaporation-type of diffuser pipe is installed Electrical power is 7.866kW after condenser, test.Power increases 0.319kW, and the percentage of power increase is 4.22%.
If improving air quantity by changing rotating speed, power will increase 14.3kW.In contrast to this, the steaming of diffuser pipe is installed Hairdo condenser energy-saving effect is notable.
In summary, diffuser pipe of the present utility model is notable using rear energy-saving effect in evaporative condenser, expands simultaneously Pressure pipe produces and installed simple, and air quantity can be greatly improved by installing the evaporative condenser of diffuser pipe, therefore, highly be applied Promote.
Although the foregoing describing embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art Member can make numerous variations or repair to these embodiments on the premise of without departing substantially from principle of the present utility model and essence Change, but these changes and modification each fall within protection domain of the present utility model.
