Description
Technical field
The utility model relates to that a kind of spoke stream toilet air-conditioning send, the spoke air supply stream lane device of air return system, belong to room air clean technology field, be applicable to cleanliness factor is had the room of requirement, such as medicine, food production workshop, the workshop of retrofit manufacturing enterprise and the aseptic ward of hospital etc.
Background technology
At present, turbulent flow clean room air-conditioning commonly used send, air return system is used by the scheme of the high efficiency particulate air filter in toilet's top layout some, the clean gas flow penetrated from indoor diffusing cover after filtering mixes with original air in toilet, makes original airborne pollutant obtain " dilution ".High efficiency particulate air filter use " point distributes " due to its top, toilet, cause indoor air flow to distribute very inhomogeneous, although this turbulent flow clean room cost and operating cost are lower, but, due to the intrinsic defect of clean indoor air flow, generally be only applicable to the toilet of cleanliness factor more than ten thousand grades and 100,000 grades.Turbulent flow clean room air blow and return mode commonly used is sent wall return air under side for top.
The structure of the air-supply passage of turbulent flow clean room is as follows:
The air-conditioning unit is used the typing complete sets of products, its machine room majority of laying unit has certain distance apart from toilet, therefore need to lay special-purpose give, return air duct connected with it, usually also need to lay special-purpose blast main road at the top, toilet and the 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 in order to carry out the air quantity adjusting.Existing turbulent flow clean room send, return air duct system process complexity, and difficulty of construction is larger, and air-conditioning air blow and return running resistance is large, causes operating cost high.
The shortcoming of turbulent flow clean room is to form " eddy current " because its flow field of sending into the pure air in toilet often causes the indoor section zone, make the harmful substance of indoor generation not discharge with minimum diffusion, cause toilet's cleanliness factor detection of dynamic effect not good enough.
At present Unidirectional air flow clean rooms commonly used is that high efficiency particulate air filter is covered with along the top, toilet, makes whole toilet form equally distributed clean gas flow, most of pollutant along with air-flow with the shortest path flow to return air inlet.Thereby 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 the 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.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, small investment, can meet that the spoke stream toilet air-conditioning that the required cleanliness class in toilet requires send, the spoke air supply stream lane device of air return system.
The utility model solves the technical scheme that its technical problem adopts:
A kind of spoke stream toilet air-conditioning send, the spoke air supply stream lane device of 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; Be evenly equipped with flow-out hole on described arc spoke stream cover, 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; Be evenly equipped with balancing orifice described all the 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 lays respectively at the above and below of toilet's top board, static-pressure box type air-supply passage and all to press the chamber between dividing plate be vent passages; All pressing the chamber between dividing plate and arc spoke stream cover is surge tank; The longer elongated layout in length direction top side wall position of length direction medium position or edge that described arc spoke stream cover is longer along the top, toilet; One end of described static-pressure box type air-supply passage is connected with pipeline for giving wind for air conditioner by the 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 that is arranged on air-conditioner air outlet.
Be positioned at that described all to press the balancing orifice on dividing plate be circular hole or bar hole, when being bar hole, the described dividing plate of all pressing, by forming more than 2, all presses the gap between dividing plate adjustable for adjacent two.
The flow-out hole be positioned on arc spoke stream cover is circular hole or bar hole.
The area S of described balancing orifice is calculated 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;
The discharge coefficient that μ is balancing orifice mouth place;
P
jpfor the average static pressure at balancing orifice mouth place, unit is Pa.
Described arc spoke stream cover is semicircle spoke stream cover.
The radius of curvature of described arc spoke stream cover is determined by the required ventilation in toilet, the radius of curvature of described 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 circulation wind lane device:
Spoke stream toilet is not because the flow field of the air-flow that its flow-out hole is sent is single direction, but uniform along arc spoke stream cover radial direction, its purification mechanism both had been different from the dilution blending effect of turbulent flow clean room, the piston action that also is different from Unidirectional air flow clean rooms air flow stream line parallel, it uses less high efficiency particulate air filter group, the flow field of indoor formation displacement stream in toilet, it has adopted new flow-out hole form and air current composition scheme, with the least possible pure air to meet the required cleanliness class in toilet.
Static-pressure box type air-supply passage and all press cavity between dividing plate to form vent passages.Because the sectional area of this vent passages is greater than the sectional area of pipeline for giving wind for air conditioner, 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 equably by all pressing dividing plate and the arc spoke stream chamber between covering.Because arc spoke stream cover inwall is provided with damping layer, make air-supply further evenly be reallocated, make to cover stream by arc spoke stream more even.In like manner, due to the drag effect of damping layer to the air-supply air-flow, make again all to press the air-supply uniformity of dividing plate to obtain further assurance.
The beneficial effects of the utility model are as follows:
(1) the utility model adopts the ventilating system of " spoke air supply stream ", uses the static-pressure box type air-supply passage, has saved volume damper, reduced give, the running resistance of air return system;
(2) layout of static-pressure box type air-supply passage of the present utility model and return air inlet, make the harmful suspended particles in toilet reach minimum at toilet's inner diffusing rate, makes the cleanliness factor in toilet reach higher rank;
(3) relatively, the high efficiency particulate air filter group of use is less, makes the Construction of Cleaning Room small investment, and energy saving in running, easy to maintenance for the utility model and Unidirectional air flow clean rooms.
