Abstract
The utility model relates to a waste gas collection and treatment device for the phenolic resin production process; the device comprises a collecting cover covered above a phenolic resin cooling conveyer belt, and an output pipe connected on the top of the collecting cover; the output pipe is sequentially connected with a waste gas absorption tank, a draught fan and a spray absorption tower, wherein a plurality of layers of mesh plates are arranged in the waste gas absorption tank, and activated carbon is filled among the mesh plates; and the top of the spray absorption tower is provided with a qualified gas emission receiving pipe. The waste gas collection and treatment device has the beneficial effects that after being collected, the waste gas is filtered and absorbed by the activated carbon and then is absorbed by water or dilute alkali liquor in a spraying way, so that the waste gas mainly containing formaldehyde and acid gas can completely reach the qualified gas emission standard, and the environmental pollution caused by the production waste gas can be completely eliminated. The waste gas collection and treatment device is simple in structure, wide in source of the adopted absorbing medium and lower in cost.
Description
Technical field
The utility model relates to a kind of gas sampling treating apparatus.
Background technology
After the phenolic resins of fusion came out from reaction pot, crystallisation by cooling solidified on cooling conveyor, the free volatilization gas of some formaldehyde and the acid solution of can overflowing this moment, and these gases are dispersed in the workshop condition can have a strong impact on health of operators.Present treating method is that the gas sampling cover is set above cooling conveyor, by pipeline and air-introduced machine outdoor atmosphere is gone in the harmful exhaust delivery in the collecting hood then, though improved the office work environment like this, the outside atmosphere environment caused bigger pollution.
The utility model content
The purpose of this utility model provides a kind of phenol formaldehyde resin production process gas sampling treating apparatus that can thoroughly eliminate exhaust emission.
The technical solution that realizes above-mentioned purpose is: a kind of phenol formaldehyde resin production process gas sampling treating apparatus, comprise the collecting hood of shroud above the phenolic resins cooling conveyor and the efferent duct that is connected in the collecting hood top, be parallel with the admission line that is connected with the bottom air inlet of waste gas tourie before the control valve of described efferent duct, in the described waste gas tourie several layers mesh plate is installed, be filled with active carbon between each mesh plate, the top exit pipe of waste gas tourie is connected to the inlet of air-introduced machine, the outlet of described air-introduced machine connects the spray absorber lower inlet by pipeline, the spray delivery side of pump is connected to the shower nozzle of spray absorber internal upper part, spray absorber bottom liquid outlet is connected with the inlet of spray pump, and the spray absorber top is provided with qualified gas discharge nozzle.
As preferably, place, described spray absorber gas outlet is provided with liquid barrier.
As preferably, be parallel with liquid supplementation pipe on the described spray pump intake piping.
As preferably, be parallel with useless spray liquid discharge conection before the control valve of the outlet of described spray pump.
As preferably, be added with alkali lye in the spray liquid of described spray absorber.
The beneficial effects of the utility model are: absorb through activated carbon filtration behind the gas sampling, spray through water or sig water absorbs again, make the waste gas that mainly contains formaldehyde and sour gas reach qualified gas discharge standard fully, thoroughly eliminated the pollution of process gas environment.The utility model is simple in structure, the absorbing medium wide material sources that adopted, and cost is lower.
