Abstract
The invention discloses a novel mine axial flow ventilation diffuser which comprises a horn-shaped diffuser shell with a small inlet and a large outlet. A single-layer wind deflector or a multi-layer wind deflector or a cross-shaped wind deflector is arranged in the diffuser shell in the wind flow direction. The shape of the section of the inlet of the diffuser shell and the shape of the section of the outlet of the diffuser shell are rectangular or circular. The internal space of the diffuser shell is divided by the wind deflector into multiple parts according to the cross section, equivalently, multiple diffusers are connected in parallel, and wind flow is distributed and diffused. By adjusting the number or the shape of the wind deflector in the diffuser, running of wind flow of a wind outlet of a mine can be adjusted, a part of kinetic energy of a draught fan outlet is converted into draught fan static pressure energy, and therefore the effective power of a ventilator is increased. The novel mine axial flow ventilation diffuser is arranged on a wind outlet of a mine ventilation system and used for an auxiliary device of the main mine ventilator, and the operation efficiency of the main ventilator can be improved.
Description
Technical field
The present invention relates to a kind of auxiliary device of Mine Ventilator, particularly relate to a kind of New Mine ventilation by axial flow fan diffuser.
Background technique
At present, coal mine main ventilator power consumption accounts for about 20% of full ore deposit power consumption, and the blower fan apparatus operational efficiency of most of mine is less than 70%, and part mine fan operational efficiency does not even also reach 50%; Operational efficiency generally on the low side has a strong impact on main fan in mine ventilation economic benefit.As can be seen here, improve chief ventilators device operation efficiency, saving power consumption is many mines problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of New Mine ventilation by axial flow fan diffuser that can improve chief ventilators device operation efficiency.
The object of the invention is to be achieved through the following technical solutions:
New Mine ventilation by axial flow fan diffuser of the present invention, comprise import little, export large flaring diffuser housing, individual layer wind deflector or multilayer wind deflector or cross wind deflector are set along wind direction in described diffuser housing.
As seen from the above technical solution provided by the invention, the New Mine ventilation by axial flow fan diffuser that the embodiment of the present invention provides, due to comprise import little, export large flaring diffuser housing, individual layer wind deflector or multilayer wind deflector or cross wind deflector are set along wind direction in diffuser housing, for the auxiliary device of main fan in mine, chief ventilators device operation efficiency can be improved.

Embodiment
To be described in further detail the embodiment of the present invention below.
New Mine ventilation by axial flow fan diffuser of the present invention, its preferably embodiment be:
Comprise import little, export large flaring diffuser housing, individual layer wind deflector or multilayer wind deflector or cross wind deflector are set along wind direction in described diffuser housing.
The import cross section of described diffuser housing and the shape of outlet are rectangular or circle.
The inner space of described diffuser housing is divided into multiple part by described wind deflector on cross section, is equivalent to multiple diffuser in parallel.
This New Mine ventilation by axial flow fan diffuser is loaded on the exhaust outlet place of mine ventilation system.
New Mine ventilation by axial flow fan diffuser of the present invention, for the auxiliary device of main fan in mine, chief ventilators device operation efficiency is improved by the use of this device, using this diffuser of the present invention as main fan in mine auxiliary device, can utilize and carry out shunting diffusion containing wind deflector diffuser apparatus to colliery exhaust outlet is distinguished and admirable, by the distinguished and admirable flowing of different passages regulate mine exhaust outlet at diffuser wind inlet place, the operation that mine exhaust outlet is distinguished and admirable can be regulated, be fan static pressure energy a part of kinetic transformation of fan outlet, thus improve ventilator useful horsepower, form a kind of brand-new mine ventilation system.Solve the problem that current mine ventilation inefficiency diffuser using effect is undesirable.
Specific embodiment:
As shown in Figure 1, for importing and exporting the diffuser housing being definite shape (rectangular or circle), middle part setting single or multiple lift wind deflector as shown in Figure 2 or cross wind deflector as shown in Figure 3.
As shown in Fig. 4, Fig. 5, Fig. 6, wind deflector is positioned over diffuser housing inside.
The present invention is as main fan diffusion system, be arranged on mine exhaust outlet place, installation form is be seated to by diffuser also according to the bore of mine well head size adjustment diffuser wind inlet above mine exhaust outlet, and the quantity of wind deflector is according to the actual ventilation of shaft production and the adjustment of well head size.
New Mine ventilation by axial flow fan diffuser of the present invention, imports and exports the diffuser housing of (bore is rectangular or circle) owing to comprising definite shape; Middle part arranges single or multiple lift wind deflector.Described wind deflector can be single or multiple lift; May also be the wind deflector of cross shape; Described wind deflector is placed in described diffuser housing.This diffuser installed by main fan in mine auxiliary device, multilayer wind deflector diffuser apparatus can be utilized to carry out shunting diffusion to colliery exhaust outlet is distinguished and admirable, by regulating quantity or the shape of diffuser inside wind deflector, the operation that mine exhaust outlet is distinguished and admirable can be regulated, be fan static pressure energy a part of kinetic transformation of fan outlet, thus improve ventilator useful horsepower, form a kind of brand-new mine ventilation system.Utilize this diffuser apparatus carry out distinguished and admirable to mine exhaust outlet air quantity and spread, reach and reduce exhaust outlet dynamic pressure, improve the object of the kinetic energy of fan static pressure and recovery exhaust outlet further, thus define a kind of main fan diffusion system completely newly.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
