The present invention and existing pump drainage wind system relatively have following outstanding substantive distinguishing features and obvious improvement:
1. the present invention adopts the blower fan air-supply to form the method for operation of eddy flow, Whirl entraining sleeve pump drainage wind, blower fan is separated fully with pump drainage gas, blower fan can be placed on outdoor, also can be placed on indoor from the clean air of outdoor extraction, draught fan impeller no longer contacts with pump drainage gas, and function only is equivalent to blowing device.The making material of Whirl entraining sleeve can be metal, also can be inorganic non-combustible type fiberglass, also can be resistant material or exotic material, a variety of selections are arranged, can be widely used in the pump drainage wind in fields such as workshop, warehouse, supermarket, food processing factory, chemical plant, hotel, hotel, subway station, stadium, mine, tunnel, underground garage.Particularly in air ambient, contain a lot of solid particles, dust, drop or corrosion thing; when perhaps environment temperature is very high; existing when directly taking out in line blower fan when using; very easily damage motor and impeller; and the spiral-flow type pump drainage wind apparatus of a kind of minute of the present invention body structure; the Whirl entraining sleeve is unblocked, so directly blower fan is protected, prolong its service life greatly.
2. the Whirl entraining sleeve utilizes the vortex fluid motion to produce powerful suction force, and a blower fan can mate one group of Whirl entraining sleeve, also can mate the combining structure of two groups or more Whirl entraining sleeve simultaneously.Through numerical simulation and experimental verification repeatedly, the suction force of Whirl entraining sleeve is directly proportional with the air supply velocity of blower fan.When using one group of Whirl entraining sleeve, the air supply duct sectional area of blower fan equals 0.8 to 1.2 times that annular eddy flow slot cross-section amasss, it highly is 1 to 1.2 times of annular eddy flow groove height, and the sectional area of inner core entrance equals 0.8 to 1.5 times of air inlet sectional area of blower fan; When using two groups or more combining structure, the air supply duct of blower fan is divided into two parts or more parts are corresponding with it, each part tangentially communicates with a Whirl entraining sleeve, and the situation during Whirl entraining sleeve of the sectional area of each part and use is consistent; Under the constant situation of the air output of blower fan, the mean wind speed of blower fan output is more big, and the air supply duct sectional area of blower fan is just more little, and the suction force of Whirl entraining sleeve will be more big.When only adopting one group of Whirl entraining sleeve, total exhaust air rate is greater than the air output of blower fan; When adopting two groups or more Whirl entraining sleeve, total exhaust air rate can surpass the twice of blower fan air output.That is to say that even blower fan does not participate in pump drainage wind just as blowing device, the Whirl entraining sleeve also can reach identical suction effect, even directly take out in line suction effect above original blower fan.As seen, the spiral-flow type pump drainage wind apparatus of a kind of minute body structure of the present invention had both realized that blower fan separates with pump drainage gas, can reach best practical function again.
3. Whirl entraining tube-in-tube structure compactness does not have complicated manufacture craft, and easy cleaning is fit to a lot of occasions and installs and uses.Particularly the blower fan air-supply is rotated at a high speed after entering annular eddy flow groove, and the air-flow of suction discharges with the swirling eddy motion.In this process, if environmental gas contains a large amount of solid particles, dust or drop, will under the centrifugal action that high-speed rotational produces, throw to tube wall and accumulation, thereby realize filtering the purpose of holding back.
4. pump drainage wind was handled when the spiral-flow type pump drainage wind apparatus of a kind of minute body structure of the present invention was particularly suitable under the adjacent area varying environment.Such as in the chemical plant, the processing of corrosive gas is in a workshop, the processing of non-corrosiveness gas is in adjacent another one workshop, so the blast pipe of blower fan can be extend into the processing workshop of non-corrosiveness gas, and the exhaust column of Whirl entraining sleeve extend into the processing workshop of corrosive gas, and the spiral-flow type pump drainage wind apparatus that such two workshops can share a kind of minute body structure of a cover the present invention can reach pump drainage wind effect simultaneously.A blower fan is realized the pump drainage wind of two cover blower fans, and power does not increase, and effect but increases doubly, so reach efficient, purpose of energy saving.
In a word, the spiral-flow type pump drainage wind apparatus of a kind of minute of the present invention body structure is owing to adopt novel cyclone technique, and taked than the reasonable configuration assembling mode; blower fan is protected; and pump drainage wind effect do not subtract, and install and function of use aspect, give user's multiple choices.
