Description
Technical field
The present invention relates to water treatment fields, and in particular to it is a kind of suitable for underground type water treatment building without air duct blow
Device.
Background technique
Underground type water treatment building has become the new direction of municipal engineering construction, it generally divides three layers: ground floor, underground
One layer and two layers of underground.Removing shaft and Pedestrians and vehicles access way mouth is arranged in ground floor, and basement one is that equipment is lifted by crane and maked an inspection tour
Space, two layers of underground setting water treatment building.Wherein basement one is that personnel mainly stay area, natural due to relative closure
Ventilation condition is poor, it is necessary to guarantee air quality in this setting mechanical ventilation system.
At present in the built underground type water treatment building in China, air duct blow is generallyd use, that is, arranges a large amount of air supply tubes
It is lifted on basement one structure roof lower part.Since underground sewage treatment works belong to flat space, there is layer height (generally 4m
~ 6m), area is big, the structural particularity more than truss, easily brought using air duct blow system pipeline is long, truss intersection is not easy to arrange,
The problems such as there are dead angle, operation energy consumption and noises for ventilation greatly, maintenance is inconvenient.Further, since the volume that air hose occupies
It is larger, the air supply mode can make building storey height increase 0.4m ~ 0.6m, about building storey it is high 1/10, to make civil engineering cost
It is substantially increased.
Summary of the invention
The purpose of the present invention is overcoming the shortcomings of existing underground type water treatment building air duct blow, one kind is provided and is suitable for
Underground type water treatment building without air hose air supply device, there is age of air and pollutant (mainly H2S) low, drafting efficiency
The features such as high with contaminant removal effectiveness, can be effectively reduced the whole buried depth of underground type water treatment building, reduce fan pressure head, save
Engineering construction initial cost, operation energy consumption and maintenance cost.
To achieve the goals above, realization of the invention is completed by following technical scheme:
It is a kind of suitable for underground type water treatment building without air hose air supply device, it is characterised in that the air supply device include give
Ventilating shaft, air intake passage and air-supply gallery, wherein
Blowing shaft part is located at ground or more, and blowing shaft is connect with the external world, for being sent into fresh air；
Air intake passage one end is communicated by blowing shaft with outdoor, and the other end is connect with air-supply gallery, and pressure fan is set in air intake passage；
Gallery of blowing is arranged along underground type water treatment building width direction, is blown to ventilation target area, in air-supply piping lane
One-way piston stream is generated, lightweight blank wall is arranged in one upper lateral part of frontage and airiness target area, and lower part is arranged close to personnel activity region
Porosity is along the changed uniform flow orifice of structures width direction.
Further, blowing shaft surrounding air inlet sets noise elimination stormproof louvre, and inside is equipped with array silencer, minimizes
The noise of air inlet avoids having an impact surrounding resident.
Further, noise elimination stormproof louvre is made of outter frame shelf, sound absorption protective panel, sound-absorbing material three parts.
Further, the array silencer metal shell wedge body formula, by metal housing frame, sound absorption protective panel, suction
Sound material, four part of mounting bracket composition, array silencer is fixed in ventilating shaft by stainless steel stent modularization, easy to disassemble
Cleaning.
Further, it is described it is a kind of suitable for underground type water treatment building without air hose air supply device, feature exists
In in order to reduce fan resistance, connected between air intake passage and blowing shaft using fillet.
Further, the pressure fan console mode is installed in the air intake passage of basement one, should compared with hanging installation
Mode can make blower as far as possible far from air inlet, influence of the noise generated when reducing fan operation to ground resident.
It further, is the airflow homogeneity for improving personnel activity region, pressure fan is small using air quantity, uniform more than quantity
Arrangement.
Further, the pressure fan is small-sized variable-frequency axial flow blower, reduces noise supporting belt spring to reduce vibration
Damper, in order to reduce fan resistance supporting belt deflector and collector.
Further, the pressure fan air outlet setting diffuser and array silencer, diffuser can reduce feeding air
Dynamic pressure, improve its static pressure.Electric control valve is arranged in the outside of pressure fan air outlet, can pass through the valve of adjusting electric control valve
Aperture regulation air output.
Further, the air-supply gallery is equivalent to a plenum chamber, can reduce the dynamic pressure into air-supply gallery air-flow, increases
Its static pressure can also weaken airstream vibration other than steady air flow obtains uniform outlet air to reduce noise.
Further, it is contemplated that construction patrol officer is mainly living on the ground that space was lifted by crane and maked an inspection tour to basement one equipment
Dynamic, the air quality of space above is not paid close attention to, therefore is installed in air-supply gallery towards personnel activity region side top
Lightweight blank wall, uniform flow orifice is installed in lower part, and the height of uniform flow orifice is slightly larger than human body average height, which can make
Near Ground air velocity is larger, sufficiently the pollutant near dilution construction patrol officer, is guaranteeing personnel zone of action air
Air output is reduced while quality, reduces operation energy consumption.
Further, different according to air-supply gallery inner air static pressure distribution, the uniform flow orifice porosity is along structures
Corresponding variation occurs for width direction.Corresponding pressure fan exit is since static air pressure is big, the porosity of uniform flow orifice,
Remaining position porosity is larger, to realize one-way piston stream.
Further, it is the airflow homogeneity for improving ventilation target area, reduces fan resistance, no air hose air supply device one
As using positive installation.It is insufficient in special circumstances in certain construction lands, device can reversely be installed.
The invention has the advantages that (1) realize underground type water treatment building without air duct blow, pass through and cancel air-supply wind
Pipe avoids the intersection conflict of air hose and other pipelines and basement one structure roof primary-secondary beam；(2) it is thrown at the beginning of reducing air hose
The buried depth of underground type sewage treatment plant is decreased while money, significantly reduces civil engineering initial cost；(3) since the present invention is sent
Wind resistance is less than traditional air pipe device, and the reduction of 6 pressure head of pressure fan can effectively reduce the operation energy consumption and blower of air supply device
Run noise；(4) uniform flow orifice 9 is set by the reasonable Arrangement of pressure fan 6 and in air-supply gallery lower exit port, realizes people
The class one-way piston flowing of member zone of action air, improves the velocity uniformity of internal gas flow；(5) occupied zone is reduced
The age of air and pollutant (mainly H in domain2S) concentration improves drafting efficiency and contaminant removal effectiveness；(6) guaranteeing personnel activity
Air output can be reduced in the case where regional air quality, reduce operation energy consumption.
