When the choice suits the system that the factory needs, demist implement the function of itself is the serious consideration element when choosing. But, still item of a few installation also can affect demist implement choice. They include demist implement predicting installation position, the choice of collect mist fan housing, and inspiratory spot position. Although demist implement install indoors, but appear to be installed about them ceaselessly at the problem outdoor. To this kind of installation, remember the following well please: Whether can be the temperature that should notice to predict to install the position to be in area above all reduced under 32 degree Fahrenheit, no matter be,now and then still is often, no matter be days,still be in night. If appeared such low temperature, so the water in water-solubility refrigerant can be frozen. Although pass demist implement the aeriform temperature of eduction will be a few higher, but discharge conduit to work to fall in environmental temperature normally, the likelihood freezes. In addition, return the case when system of Lv of take an examination is shut. Demist implement put can cloggy catchment on the ice mediumly, still can jam filter. Collecting pure oil other perhaps not dissolve when the liquid at water, the viscosity of the fluid is one of influencing factor. Although oil won't be frozen when 32 degree Fahrenheit, but as climate become cold its meeting thicken is stiff, restrain its to be mixed from filter discharge conduit to be discharged. When collecting water-solubility refrigerant, lunt or moist air discharges the meeting in the microtherm air outdoor to bring about water vapour to condense, produce Shui Yun thereby. This is similar to filter the system is not effective, if the plant area of the program is located in,perhaps near residential area, so the emission complaints are heard everywhere that these the people that suffers its to affect will be right seeing. This meeting draws place or the examination of bureau of national environmental protection (undertake probably investigating) . Should pay close attention the demist outdoor implement packing is seamed, electric join, measure crimp mouth, and similar component, cause undesirable effect in order to ensure rainwater and other weather situation are done not have to the function of equipment. The proposal is demist implement increase ceiling and / or local outer garment, the demist that concerns with weather with be being reduced as far as possible implement breakdown. If do not have a law to accomplish such, should be equipment so discharge a canal to install the cover that prevent rain. This will make demist implement vertical discharges a canal to turn to lower part, affect the odds of equipment interior with reducing rainwater and climate as far as possible. The design of fan housing although demist implement be installed directly or be in through conduit installation machine tool crust, but the fan housing design with the demist application special need that has about 10% . These use the old-style machine tool that includes more than 20 years; Exceed large part for treatment and the custom-built machine tool that cannot close completely; The machine tool with topmost very main to to load spare parts and cutting tool entrance; And besides metallic cutting and figuration, the situation that apply a standard to abide by indoor air quality and needs to undertake air is purified. When designing custom-built fan housing, " Industrial Ventilation " the likelihood is one of best reference material origin, it is conference of hygienists of American government industry recommend regulations manual what promulgate originally. Included a lot of fan housing designs among them, and recommends according to fan housing dimension air current computation. The specific measure of fan housing is not made clear sometimes, to determine proper fan housing size, how do the factory should consider mirage arise. Be forms because of heat treatment mist? Is mirage from the machine tool or refrigerant nozzle arises and along a direction ejective? Still diffused along each direction? The key depends on examining the generation fountainhead of mirage directly, and abide is worn the trace observation of mirage, is not to examine treatment process upper part or the mirage around. Below most circumstance, the much of mirage along a direction outspread, this makes its are arrested easily collect, what what fan housing should need like it is enough in that way big, in order to catch the mirage that market source place produces. Additional, it still should stand by mirage as far as possible to generate a source. After the measure that devises good fan housing, the factory wants computation to need how many air current to catch collect mirage (following watches are shown) . To decide the throughput that fan housing place needs, apply equality Q=V (10 X2 +A) , among them the throughput that Q is equal to minutely place to need (the unit is cubic metre foot) , v is the minutely speed that catch market (the unit is foot) , x is the distance with fountainhead (the unit is foot) , the surface that A is equal to fan housing is accumulated (the unit is square foot) . Source of generation of mirage of fan housing distance is closer, fan housing is smaller, the throughput that discharges mirage place to need will be smaller, demist implement smaller also.
