Description
Technical field
The present invention relates to that a kind of vector flow clean room air-conditioning send, the spoke air supply stream lane device of air return system, belong to room air clean technology field, be applicable to room cleanliness factor being had to requirement, such as medicine, food production workshop, the workshop of retrofit manufacturing enterprise and the bio-clean treatment unit etc. of hospital.
Background technology
At present, conventional turbulent flow clean room air-conditioning send, air return system uses scheme by the high efficiency particulate air filter in toilet's top layout some, the clean gas flow of diffusing cover injection indoor mixes with air original in toilet after filtering, and the pollutant in original air is obtained " dilution ".Because the high efficiency particulate air filter at its top, toilet uses " some distribution ", cause room test very uneven, although this turbulent flow clean room cost and operating cost lower, but due to the defect that clean indoor air flow is intrinsic, be generally only applicable to the toilet of more than ten thousand grades and 100,000 grades cleanliness factors.It is that wall return air under side is sent on top that turbulent flow clean room commonly uses air blow and return mode.
The structure of the air-supply passage of turbulent flow clean room is as follows:
Air-conditioner set uses sizing complete sets of products, there is certain distance its machine room most distance toilet of laying unit, therefore need to lay special to give, return air duct connects with it, usually also need at top, toilet to lay special blast main road and blowpipe road is connected with the plenum chamber of dispersion, between main air supply duct and blowpipe road and plenum chamber, be provided with control valve to carry out air quantity adjustment.Existing turbulent flow clean room send, return air duct system process complicated, and difficulty of construction is comparatively large, and air-conditioning air blow and return running resistance is large, causes operating cost high.
The shortcoming of turbulent flow clean room is because the flow field of its pure air sent in toilet often causes indoor section region to form " eddy current ", the harmful substance of indoor generation can not be discharged with minimum diffusion, cause cleanroom cleanliness detection of dynamic less effective.
At present conventional Unidirectional air flow clean rooms is covered with along top, toilet by high efficiency particulate air filter, makes whole toilet define equally distributed clean gas flow, and most of pollutant flows to return air inlet with the shortest path along with air-flow.Thus can reach very high cleanliness factor, be generally used for the environment of 100 grades of cleanliness factors.In addition, Unidirectional air flow clean rooms adopts foot level grill air return system, causes involving great expense.
The shortcoming of Unidirectional air flow clean rooms is that cost is too high, and Unidirectional air flow clean rooms is built and maintenance difficulty is larger.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of structure is simple, small investment, can meet that the vector flow clean room air-conditioning that the cleanliness class needed for toilet requires send, the spoke air supply stream lane device of air return system.
The technical solution adopted for the present invention to solve the technical problems:
Vector flow clean room air-conditioning send, a spoke air supply stream lane device for air return system, it is characterized in that by toilet's top board, static-pressure box type air-supply passage, all presses dividing plate, arc spoke stream cover, damping layer and high efficiency particulate air filter group to form; Described arc spoke stream cover is evenly equipped with flow-out hole, and described damping layer is affixed on the inwall of arc spoke stream cover, and described damping layer is the filter course that nylon material is made; Balancing orifice is evenly equipped with described all pressure on dividing plate, described static-pressure box type air-supply passage, all press between dividing plate, arc spoke stream cover and toilet's top board and be sealed connected together by connector, described static-pressure box type air-supply passage and arc spoke stream cover lay respectively at above and below toilet's top board, static-pressure box type air-supply passage and all press the chamber between dividing plate to be vent passages; All the chamber between dividing plate and arc spoke stream cover is pressed to be surge tank; The length direction medium position that described arc spoke stream cover is longer along top, toilet or along the longer elongated layout in length direction top side wall position; One end of described static-pressure box type air-supply passage is connected with pipeline for giving wind for air conditioner by high efficiency particulate air filter group, and described pipeline for giving wind for air conditioner is connected with the air-conditioner air outlet plenum chamber being arranged on air-conditioner air outlet.
The balancing orifice be positioned on described all pressures dividing plate is circular hole or bar hole, and when for bar hole, described dividing plate of all pressing forms by more than 2 pieces, all presses the gap between dividing plate adjustable for adjacent two pieces.
The flow-out hole be positioned on arc spoke stream cover is circular hole or bar hole.
The area S of described balancing orifice calculates by uiform section balanced ventilation pipeline theory, and computing formula is as follows:
In formula, Q is described vent passages air output, and unit is m
3/ s;
μ is the discharge coefficient at balancing orifice mouth place;
P
jpfor the average static pressure value at balancing orifice mouth place, unit is Pa.
Described arc spoke stream cover is semicircle spoke stream cover.
Radius of curvature ventilation needed for toilet of described arc spoke stream cover determines, the described radius of curvature of arc spoke stream cover, the size of flow-out hole and the triplicity of perforate density determine the wind speed v of arc spoke stream cover exhaust vent, and the scope of described wind speed V is: 0.3m/s<V<0.5m/s.
The operation principle of described spoke stream ventilating channel device:
Vector flow clean room is not single direction because of the flow field of the air-flow that its flow-out hole is sent, but arcuately spoke stream cover radial direction is uniform, its purification mechanism had both been different from the dilution blending effect of turbulent flow clean room, also the piston action that Unidirectional air flow clean rooms air-flow streamline is parallel is different from, it uses less high efficiency particulate air filter group, the flow field of indoor formation displacement stream in toilet, it have employed new flow-out hole form and air current composition scheme, with the least possible pure air to meet the cleanliness class needed for toilet.
Static-pressure box type air-supply passage and all press the cavity between dividing plate to form vent passages.Sectional area due to this vent passages is greater than the sectional area of pipeline for giving wind for air conditioner, and after air flows into this vent passages, flow velocity reduces, and the part dynamic pressure of air-flow can be converted into static energy, makes air uniformly across the chamber of all pressing between dividing plate and arc spoke stream cover.Because arc spoke stream cover inwall is provided with damping layer, air-supply is evenly reallocated further, make to go out stream by arc spoke stream cover more even.In like manner, because damping layer is to the drag effect of air-supply air-flow, the air-supply uniformity of all pressing dividing plate is made again to obtain further guarantee.
Beneficial effect of the present invention is as follows:
(1) the present invention adopts the ventilating system of " spoke air supply stream ", uses static-pressure box type air-supply passage, eliminates volume damper, reduce give, the running resistance of air return system.
(2) layout of static-pressure box type air-supply passage of the present invention and return air inlet, makes the harmful suspended particles in toilet reach minimum at toilet's inner diffusing rate, makes the rank that the cleanliness factor in toilet reaches higher.
(3) the present invention compares with Unidirectional air flow clean rooms, and the high efficiency particulate air filter group of use is less, makes Construction of Cleaning Room small investment, and energy saving in running, easy to maintenance.
