Abstract

The invention provides a sleeve type centrifugal dehumidifying and purifying ventilator, relates to and utilizes a centrifugal fan; with the principle of full-angle direct exhaust, when the centrifugal fan works, a flow field with minimum fluid emission resistance is formed, thus the problems of fluid vortex disorder and motor energy internal friction caused by the design of a volute housing of a traditional centrifugal fan are prevented. The effect of impellers of the centrifugal fan in the centrifugal separation action force is improved, the structural design manner of sleeve type ventilation is adopted, the effects of separating gas from liquid and improving the exhaust of the centrifugal fan are realized, and the characteristics of the structure are utilized, thus the problem of dehumidification drying during the circulating or exhaust process of high wet air flow is solved. The designed sleeve type centrifugal dehumidifying and purifying ventilator is matched with a wet type air purifier for use, the effect is particularly obvious on the basis of improving the air purification efficiency, and the ventilator has unique use and effect in the fields of environmental protection and energy saving.

Description

Telescopic centrifugal except wet purification ventilator

Technical field

Centrifugal blower is the equipment of (to, air draft) as ventilating, and no matter is at all types of industries manufacturing shop, thermal power plants, or public area, hospital operating room, underground railway, tunnel etc., and its application is extremely extensive.Exemplify the ventilation in thermal power plant, its power consumption accounts for 30% left and right of total power consumption, ventilates and has consumed a large amount of disposable energy.Therefore, the design and fabrication of research and transformation centrifugal fan, improves its effect, for energy efficiency, has great importance.Meanwhile, utilize the fluid mechanics feature of centrifugal blower, carry out the design and fabrication of new concept, reach more perfect ventilation effect, especially the application aspect circularly purifying ventilation, realizes again the effect to gas dehumidification and purification.These designs all have good realistic meaning at energy-conservation and field of Environment Protection.

Background technique

The centrifugal blower fan blade wheel that traditional people's power ventilator adopted in the past and ventilation body (spiral case or straight tube) design, all exist function singleness and effect loss compared with people's problem.

At some industrial sites, such as: between manufacturing shop, smelting and power station, Coal Exploitation tunneling, underground railway, also have some large-scale indoor public places, especially large-scale library, gymnasium, building are indoor, need to be in the winter time incubated the place of interior circulating ventilation, the traditional ventilation equipment that use, all exist the indelible series of problems of secondary pollution that in energy consumption waste and air-flow, moist particulate pollutant causes.The ventilator of tradition people power, highly energy-consuming, has increased user's operating cost, has aggravated whole society's public energy source problem in short supply.

Adopt the ventilation equipment of invention design, can either meet the energy-saving and cost-reducing demand of modern society, can play again air purification effect to a certain degree, especially in conjunction with the coupling of field of Environment Protection liquid-type off-gas cleaning equipment, aspect the air purification of polluting in ventilation and dedusting, removal, effect energy-conservation and that purify is more remarkable.

Summary of the invention

Technical problem

1. the outstanding disadvantage of traditional centrifugal blower volute housing, is that ventilation effect is low.Fluid after centrifugal blower fan blade wheel centrifugal action, density increases, pressure increases, and moment assembles, the active force state that fluid is pressed after front squeezing.The fluid of assembling produces towards the lower outside of pressure the extruding of expanding, and finally on corresponding inclined-plane, 40 ° of angles of less than, leaves Centrifugal Fans Shell, completes fluid drainage.In this process, the fluid with malleation pressure, in the diffusion angle of 360 ° of centrifugal wind wheels, area corresponding to angle that only has 40 ° of left and right, supplying with compression fluid directly discharges, and space on all the other corresponding angle areas in 320 ° of left and right is all the space that the fluid of pressurized gathering pushes mutually.On this space, reality is exactly the fluid with the higher pressure pressure of inertia potential energy, and the extruding that is subject to the high-pressure liquid of rear generation promotes and moves ahead.Before and after this, between fluid, produce mutual drag effect, thereby reduced the centrifugal force that centrifugal wind wheel produces, caused the power that motor produces to produce in-fighting, reduced motor effect, so the problem of produce power waste.

2. the design of traditional standardized centrifugal blower, can not meet in specific resistance coefficient flow field, especially the flow field under higher drag coefficient state, the work requirements of ventilation within the unit time, other materials that can not meet moist fluid and contain larger quality are blended in the discharge of the fluid in fluid, the demand of the reasonable distribution in effect in discharge amount and delivery pressure.

3. fluid (liquid) and the wherein material of other compositions (impurity), the effect of separated gathering later and water conservancy diversion, shunting under centrifugal action.

Solution

1. the present invention takes telescopic centrifugal Design of ventilation, motor and wind wheel are taked axially direct-connected mode (Fig. 1), motor and impeller shaft to be sleeved on 101 urceolus within, within motor is sleeved on again 201 inner sleeves, thereby completed the fluid after centrifugal impeller pressurization, with the direct ventilation on 360 ° of corresponding areas of full angle.Therefore, overcome the design of traditional centrifugal blower volute, the disadvantage that mutually reduces power that fluid produces in flow process, has improved the useful horsepower of motor greatly.

2. centrifugal blower fan blade wheel is with 360 ° of full angle air drafts, there is the problem of 90 ° of knuckle wind directions intuitively, be actually from the centrifugal impeller flow direction of pressurized dispatch radially, its line angle degree is to be greater than the line angle of 125 ° of 90 °, to adopt 104 diving boards, 105 guide plates and 105 to carry out compound plate, set intervention plate face forms formed round and smooth streamline labyrinth, finally forms the flow field of minimum drag.

3. for centrifugal blower unit time flow and wet type dirt and its carrying gas centrifuges designing requirement, dispensed motor is at centrifugal impeller flow and operating on centrifugal force, the power in this two aspects power.By adjusting fan blade meridian plane and the multistage winged petiole of increase, blade, cut the compound mode of wind angle, and the power of motor that reasonable selection matches and rotating speed, make full use of motor energy, ensure required flow, improving again the optimum efficiency of gas, liquid centrifugation, solved in specific resistance flow field, is again larger resistance coefficient flow field, and the requirement on the unit time flow under particular requirement, solved the unappeasable problem of design of the centrifugal blower of traditional standardized.

Beneficial effect

Improved power of motor efficient, reasonable distribution energy, the effect of having played removal moisture drying and having removed dirt for exhausting air.
