The using method and the working principle of the device are as follows: the filter mechanism 4 is first placed in the corner of the spray booth and the fan 406 is then connected to the controller 307 by a second wire 407, since the spray booth is a closed room with filtered air for spraying paint on the treated work pieces. In the gas safety management, the paint thinner mainly contains xylene, the mass of the xylene is greater than that of air, so the filtering mechanism 4 needs to be placed on the ground, then the xylene is fixed through the fixed lining plate 1, the horizontal position of the detection mechanism 3 is adjusted through the telescopic rod 2, after the adjustment is finished, the combustible gas detector 304 can be connected with the controller 307 through the first lead 306, the number of the combustible gas detectors 304 can be added according to the size of a paint spray booth, the paint spray booth can be monitored in real time, when combustible gas exists in the paint spray booth, the combustible gas concentration in the paint spray booth can be detected through the combustible gas detectors 304, when the combustible gas enters the detectors, oxidation reaction (flameless combustion) is caused on the surface of a platinum wire in the gas detector 305, the temperature of the platinum wire is increased by the heat generated by the combustible gas, the resistivity of the platinum wire changes, whether the concentration of the xylene reaches the combustion standard or not is detected, when the concentration of the xylene exceeds a set mark, an instruction is sent to an alarm 309 and an alarm lamp 310 through a controller 307, an alarm sound is sent out when the alarm 309 receives a signal, so that a worker is reminded, the alarm lamp 310 sends out a flickering light, the concentration index of the xylene can be observed through the flickering frequency of the alarm lamp 310, when the spray booth starts to work, a water pump 314 is started, the water pump 314 pumps pure water in the water tank 301, the pure water flows out through a water discharge pipe 315 to form a water column, the water column falls down at a certain height by larger water flow, impacts on a round cover 317, a layer of thicker water film is extended from an impact point to the periphery, and the flow of the water film takes inertia force and surface tension as leading factors, the water film continuously moves forward while overcoming the surface tension pull of the water film, when the edge radius of the round cap 317 is smaller, the water film cannot obtain enough lateral component force because of overlarge deflection angle of normal viscous force, so that a larger deflection radius is maintained, the round cap 317 directly separates the water film to form a spherical water film, but the falling water does not do parabolic motion, the falling water is pulled by the surface tension of the water films at two sides along the tangential direction besides gravity, the resultant force points to the circle center, so that the water film continuously decelerates in the radial direction until the direction moves, the falling water film moves along the surface under the action of the viscous force and the atmospheric pressure after contacting a cylinder, so that an approximately spherical cavity is formed, and due to the surface tension of the water, the water film keeps the trend of radius shrinkage while falling under the gravity, when the horizontal speed almost disappears and the downward speed is not slower, the effect of the surface tension of the water film is greater than the inertia force and is dominant, the water film with an annular horizontal section is folded towards the circle center, so that the water film suddenly turns and falls, the water film without weight falls is connected into a whole due to viscosity, meanwhile, according to the quality continuous theorem, the thickness of the water film becomes thinner and thinner along with the increase of the falling speed, the resultant force of the surface tension pointing to the circle center is continuously received, the water film converges towards the center along an arc path to form a water ball, the falling pure water falls on the first disc 303, flows into the water conveying pipe 312 through the first round hole 311 and finally flows into the water tank 301 to form a cycle, so that the consumption of water resources can be saved, the cost is reduced, the spherical water film can block paint with larger adsorbed particles, the inner part of the water film is hollow, and the combustible gas detector 304 in the water film can not be influenced, because the quality of xylol is greater than the air, and is insoluble in water, xylol will fall downwards like this, will enter into the gas detection head 305 of bottom, and then detect the xylol concentration, because the paint is given by the water film at top and is blockked, so just can not enter into inside the gas detection head 305, just solved because the special operational environment in spray booth, free paint causes the jam to detecting the head very easily in the air to influence the detection effect's of device problem.

When the combustible gas detector 304 detects that the concentration of xylene in the paint spray booth is too high and reaches a combustion standard, the fan 406 is started, and the fan 406 generates a suction force downwards, so that gas in the paint spray booth flows upwards from the bottom of the filter box 401, and the gas passes through the biological membrane 403 in the flowing process of the filter box 401. The core of the technology for processing organic waste gas containing 'three benzene' by a biological method is a biological membrane 403, the basic principle is that a microorganism breeding technology is adopted, a plurality of types of special microorganism strains are formed through cultivation, domestication and enrichment, then the microorganism strains are inoculated on the surface of a porous filler to form a biological membrane layer, when waste gas containing a plurality of volatile organic matters flows through a filter box 401, due to the diffusion effect, pollutant substances in the waste gas are transferred onto the biological membrane 403, the biological membrane 403 performs a biochemical reaction through microorganism enzymes in the growth and propagation processes under a proper environmental condition, organic components in the waste gas are used as nutrient substances and are degraded into carbon dioxide, water and cell constituent substances, so that the purpose of purifying the waste gas is achieved, waste water generated in the purification process flows into a water collecting tank 410 at the bottom, the spray booth is not polluted, meanwhile, manual opening and exhaust dispersion are not needed, therefore, even if an alarm signal sent by an alarm 309 is not found manually, a filter mechanism 4 can also filter and purify the gas in the spray booth, so that the concentration of combustible gas in the spray booth is reduced, and the spray booth is increased in the safe paint.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and modifications of the invention can be made, and equivalents of some features of the embodiments and modifications can be made without departing from the spirit and scope of the invention.
