Description

Spiral case centrifugal multiblade environmental protection special fan

First, technical field

This technology is exclusively used in atmosphere pollution in environmental protection：Oil smoke vapor PM2.5 COMPLEX MIXED polluted gas source It administers.

2nd, background technology

1st, in this technology without before, used spiral case centrifuges leafy wind turbine, centrifugal-fan-type axial fan, is used for It inhales, in line or cooling dehumidifier etc. of blowing.

2nd, found during the design of invention kitchen PM2.5 and pollutant air cleaning machine, manufacture, use and repair and maintenance Spiral case centrifuges leafy wind turbine, and impeller has centrifugation grease, and grease is allowed to polymerize, and wraps up the effect of dust and PM2.5 particulate matters： Oil smoke, vapor with mix complicated gas and various particulate matters enter wind turbine after, like into a small-sized oily water mist dust-removing system System, so I just generates design spiral case centrifugal multiblade environmental protection special fan, tool purification (reception) oil smoke aqueous vapor, PM2.5 etc. The thought of the functions such as particulate matter mixing complex material, and tested, effect is fine.Experimentation：Utilize the electricity of 180W power Machine drives common leafy wind turbine, in the case of 1450 revs/min of impeller, polluted gas (during culinary cuisine frying) grease PM2.5 etc. What the particulate matter in complex mixture can be dissolved in grease in wind turbine is dissolved in grease, it is impossible to be dissolved in the particulate matter of grease by grease bag Spiral case wall is thrown to after wrapping up in rebound back again impeller, is repeated, random partial is by wind-force feeding atmosphere pollution face bigger, pattern It is wider.Put the process of dirt from dedusting to extension, here it is it is to be solved the problem of.

3rd, find that the aggregation feature that expand pollutant must increase the contact surface of impeller blade and pollutant under study for action The general centrifugal multiblade fan blade number of product is 60,1450 turns per minute of motor, then rotates 24 turns each second.That is rapidly Pollutant number is dished out as 60 leaves in the section of impeller generation each second of rotation, and section × 24 revolutions per second=1450 blade sections/second are general During logical centrifugal multiblade blower fan work, generate 1450 sections each second and fly out pollutant under the action of the forces of the wind closely 90% Spiral case is flown to, and the impeller that rebounds back, blade or converges at spiral case.Be repeated, 10% or so pollutant it is in line enter air.In wind Under the action of power last more than 95% pollutant with minimum particle with the wind it is in line enter air, spread farther, contaminated area bigger； Here it is the dedusting in wind turbine, pollution generation and the diffusion process of dirt are made outside wind turbine.

4th, to solve the above-mentioned problems, spiral case centrifugal multiblade environmental protection special fan has then just been invented.

3rd, the content of the invention

1st, the fan blade of common centrifugal multiblade wind turbine is 60, and environmentally friendly special fan blade design is 72,360 ° of circumference Often degree installation 2, and pollutant contact area increase 20% throw to wind with tangentially the fly out pollutant speed in face of every paper money clock 1740 Machine spiral case wall creates conditions for more than 90% pollutant of receipt of subsequent.

2nd, every 0.618 in impeller axle vertical direction at install totally three pieces of a concentric circles gusset, as Fig. 3, D, C, E, B for electricity Machine direction end, A are air inlet end, and 1. purpose is to increase impeller intensity, reduce vibrations, noise reduction.2. it is control grease section Fly out direction, i.e., orientation flies to receiver under the action of the centrifugal force, stronger to the receiving ability of pollutant with sharp receiver, absorption Depth is deeper, running away (see attached drawing 3) under windproof power effect.

3rd, receiver is made of plant fiber, is fixed between wind turbine iron spiral case and metallic sieve, receiver inner casing geometry Shape is identical with centrifuging leafy volute of blower geometry, and during blower fan work, the grease PM2.5 pollutions converged on blade are complicated mixed Object is closed under the escorting of gusset, spiral case is flown in orientation section direction.And the reception of the receiver plant fiber on spiral case is fixed on, The receiver prevents the rebound of oily wastewater pollution object to spread (meaning for having careless ship to borrow arrow), after work residual temperature by water evaporation, And other materials are then stayed in plant fibre is.Receiver is made of plant fiber and plant fiber of the grease absorption than more than 1: 1, Ability with stronger absorption oil smoke aqueous vapor PM2.5 and other particulate matters.Plant fiber receiver adds the intensity of spiral case It reduces vibrations, there is certain sound-absorbing erasure effect (see attached drawing 1, attached drawing 2 and attached drawing 4).

3rd, in air outlet installation taper oil smoke aqueous vapor pollution mixture plant fiber receiver, being equivalent to increases in air outlet It is mounted with muffler (see attached drawing 1, attached drawing 2).

The 4th, as long as culinary art or industrial production, burning grease type will generate oil smoke vapor and PM2.5 COMPLEX MIXED pollutants Place all suitable for installing and using the wind turbine, which is used in combination effect with kitchen PM2.5 and polluted gas clearing machine can be more It is good.
