Description
Technical field
The present invention relates to the technical field of air purification processing containing paint, in particular to a kind of paint spray booth to paint processing method.
Background technology
The surface pressure spray process of automobile, refrigerator, air-conditioning, phone housing and notebook accessory etc. is made in paint spray booth
Industry, during auto spray painting machine people and manual spray gun spray object, part paint directly acts on the table of spraying object
Face, and 30%~70% or so paint is respectively enterd in the form of coating cloud in air, air and environment around serious pollution；Make
Extensively using water curtain type paint spray booth in industry, purified treatment is carried out to coating cloud, but can be formed in cascade and fall paint, is on the one hand easy to block
Circulation line, the normal operation for influencing purification system, and then influence coating quality；On the other hand recirculating water purification effect can be reduced
Rate promotes recirculated water corruption smelly, increases recirculated water and replaces number, influences to produce.
Invention content
The object of the present invention is to provide a kind of good purification, paint spray booth simple in structure paint processing system and its paint
Processing method.
To achieve the above object, the technical solution adopted in the present invention is：
Paint spray booth paint processing method includes the following steps：The first step, according to the volume V of paint spray booth and rate of ventilation n come
Determine air quantity Q1, the Q1=n*V of paint processing unit, wherein n=60~80 time/h；Second step determines paint according to air quantity Q1
The stringing in room and air port and air hose each section caliber, to determine wind speed, wherein the wind speed v1=3~5m/s in air port, air hose
Change grade branch pipe in wind speed v2=6~9m/s, wind speed v3=8~12m/s in the supervisor of air hose；Third walks, and determines the wind of wind turbine
Measure Q, Q=(1.05~1.15) Q1；4th step determines the pressure P wind of wind turbine, P wind=(1.05~1.15) P pipes；And system
Drag overall：P is total=P1+P2+P3；Wherein：P1 is the sum of change grade branch pipe and supervisor's resistance of air hose；P2 is local resistance, including
The sum of air-valve, elbow, reducing, into or out air port, air port resistance；P3 is equipment resistance, including paint processing system, Fan Equipment
The sum of resistance；The air velocity of 5th step, flow slowing down room is controlled in 1~3m/s；6th step, the gas velocity of gas scrubbing room
Degree control is in 1~2m/s, and water speed control is just being atomized；7th step, the wet gas come out from gas scrubbing room is through gas-liquid
Realize that air-liquid separation is discharged by wind turbine again in separation chamber.
Preferably, rate of ventilation n values are n=75 times/h.
Preferably, the wind speed v1=4m/s in air port；Wind speed in the change grade branch pipe of air hose：V2=7m/s；And the supervisor of air hose
Interior wind speed：V3=9.5m/s.
The beneficial effects of the invention are as follows：By the way that in the reasonable stringing in Workpiece painting region and installation air port, sky can will be dispersed in
In coating cloud be collected；After band coating cloud air-flow enters gas reduction chamber, high-speed flow slows down suddenly, the heavier paint of proportion point
Son detaches due to inertia with air, and air-flow is made to play primary purifying；After entering back into gas scrubbing room, air-flow is by the hundred of first partition
Leaf air port flows to the air grille of second partition, forms air-flow up, and atomizing spray head then atomized water spray from top to bottom, is formed
Water, gas convection current expand gas and water contact area, can largely remove the harmful substance in air-flow, further be purified to air-flow；Through gas
The air-flow that body washing chamber comes out contains a large amount of moisture, into after gas-liquid separation chamber, using air velocity, makes gas logical in air-flow
The first orifice plate of road inner impact and the second orifice plate, it is different using air-liquid density, make liquid droplet during shock, makes liquid
It is attached on orifice plate, makes gas-liquid separation；It is final it is purified after air directly excluded by wind turbine.The paint processing system is compared
Water curtain type paint spray booth is more simplified in structure, can reach by the air quantity and pressure that control wind turbine and is greatly discharged better than national standard
The air purification effect of standard, and water curtain type paint spray booth is compared, operating cost is greatly reduced.

The paint processing unit 3 includes closed cavity, and the closed cavity is separated into the air-flow being laterally arranged in order
Reduction chamber 31, gas scrubbing room 32 and gas-liquid separation chamber 33, the top of the flow slowing down room 31 is equipped with to be connected with the air hose 2
The air inlet pipe 302 connect；Separated by first partition 303 between the flow slowing down room 31 and the gas scrubbing room 32, it is described
The hypomere of first partition 303 is equipped with air grille 304；Pass through between the gas scrubbing room 32 and the gas-liquid separation chamber 33
Two partition boards 305 separate, and the epimere of the second partition 305 is equipped with air grille 304；The top of the gas scrubbing room 32 is also set
There are several atomizing spray heads 306；Compartment of terrain is equipped with vertical the first orifice plate 307 and the second orifice plate in the gas-liquid separation chamber 33
308, first orifice plate 307 is extended by the top down of the gas-liquid separation chamber 33, and second orifice plate 308 is by the gas-liquid
The bottom of separation chamber 33 upwardly extends, and the gas-liquid separation chamber 33 is made to form the gas channel curved；The escape pipe 301 is set to
The tail end of the gas channel.
The outer bottom of the paint processing unit 3 is equipped with circulating water pool 5, and the circulating water pool 5 is separated by filter screen 51, institute
It states circulating water pool 5 and does not filter side and be connected to the paint processing unit 3, filtering side passes through circulating pump and the atomizing spray
First 306 connection.
The paint processing method that the paint spray booth paints processing system is as follows：One, according to the volume V (m3/ times) of paint spray booth and
Rate of ventilation n (secondary/h) paints the air quantity Q1 (m3/h), Q1=n*V, wherein n=60~80 time/h, one of processing unit to determine
As take n=75 times/h that can reach preferably effect.
Two, stringing and air port (air port there must be regulatory function) of paint locker are determined according to air quantity Q1, then coordinate air hose each
The setting of part caliber determines wind speed, generally by the air containing paint concentrate the place occurred centered on stringing and installation air port,
Wind speed determines as follows：Wind speed v1=3~the 5m/s in air port, preferably 4m/s or so；Wind speed in the change grade branch pipe of air hose：V2=6
~9m/s, preferably 7m/s or so, too greatly, windage is too big, and the blower pressure provided is too big, and operating cost is high；It is too small, air hose
Equipment investment is too high；And wind speed in the supervisor of air hose：V3=8~12m/s, preferably 9.5m/s or so；Air hose it is tubular general
Based on rectangle, material generally uses zinc-plated plate material, and resistance coefficient is smaller, while easy to repair.
Three, the air quantity Q of wind turbine, usual fan delivery value are determined：Q=(1.05~1.15) Q1.
