The wind force of off-gas treatment fixes spray paint house method

Roughly take a breath of means room bulk increases safe cost 20 times according to the circumstance again. Want to know everybody how look upon this problem? Is computation right incorrect? Ask the room is airtight even?

Example is as follows:

Use a requirement, repair place of room of spray paint of lacquer of knead dough of room of lubricious spray paint to produce waste gas to undertake handling to its now. The paint that you use is oily lacquer (PU lacquer) , the use that its repair agent of paint of house of lubricious spray paint, solidify and thinner deserves to be paint than the circumstance: Solidify agent: Thinner =1:0.5:1.5; The use of agent of paint of house of spray paint of its face lacquer, solidify and thinner deserves to be paint than the circumstance: Solidify agent: Thinner =1:0.5:0.6. Paint (PU lacquer) for polyester coating; Thinner composition is colophony water, colophony water is the organic dissolvent that place of this alkyl of octane, Ren, ethane, xylene, 3 toluene is allocated and becomes. The composition of organic waste gas that in after add is mixed, painting namely, can volatilize basically is total hydrocarbon of xylene and blame firedamp.

Show an user room of individual spray paint paints use quantity makes an appointment with 90~100 kilogram every classes / order, the about 140 kilogram when the biggest dosage / order, working hours uses dual class to be made, every work 10 hours (grow about 6 hours when actual and effective spray paint) , room of every spray paint uses a spray gun. Over all dimension grows room of face lacquer spray paint 8 meters of * are 8 meters wide * is 3.3 meters tall (among them the half is 4 meters long * is 8 meters wide * is 3.3 meters tall for air area, connect) , send new wind by machine of 2 air cooling (2.2KW of power of engine of every air cooling, wind force 14000m3/h) , gush room sets 1 to grow 3.7 meters of * 1.8 meters tall stage of spray paint of water shade type; Over all dimension grows room of the spray paint that write scene 12 meters of * are 8 meters wide * is 3.3 meters tall (grow 7.7 meters of * among them 8 meters wide * is 3.3 meters tall room of the lacquer that it is tone and air area, connect) , send new wind by machine of 3 air cooling (2.2KW of power of engine of every air cooling, wind force 14000m3/h) , gush room sets 1 to grow 3.7 meters of * 1.8 meters tall stage of spray paint of water shade type.

Spray paint craft basically is comprised by working procedure of solidify of spray paint, air, paint waste gas basically is in the working procedure such as solidify of spray paint, air volatilizes, of paint on lacquer rate is pressed 70% plan, the waste gas contaminant that spray paint working procedure volatilizes is occupied about 30% , the waste gas contaminant that air solidify working procedure volatilizes is pressed 80% plan. Room of individual spray paint paints use quantity makes an appointment with 140 kilogram by the biggest dosage every classes / order computation. Room of the spray paint that write scene presses 1:0.5:1The paint of.5 is used deserve to compare a situation, the contaminant =46.7 kilogram that paint volatilizes / order *30%=14 kilogram / order; The contaminant =70 kilogram that thinner volatilizes / order *80%=56 kilogram / order; Every basic cycle time grows 10 hours when spray paint (actual and significant basic cycle time is 6 hours) , the contaminant that volatilizes hourly namely is 11.66 kilogram / hour; Room of face lacquer spray paint presses 1:0.5:0The paint of.6 is used deserve to compare a situation, the contaminant =66.7 kilogram that paint volatilizes / order *30%=20 kilogram / order; The contaminant =40 kilogram that thinner volatilizes / order *80%=32 kilogram / order; Every basic cycle time grows 10 hours when spray paint (actual and significant basic cycle time is 6 hours) , the contaminant that volatilizes hourly namely is 8.66 kilogram / hour.

The chroma of the biggest processing of recombine purifying device, computation determines systematic wind force, can see from the unit how to calculate.
