Embodiment Construction

[0036] The present invention will be further described below with reference to specific embodiments in conjunction with the accompanying drawings, so as to better understand the present invention.

[0037] refer to figure 1 , a treatment system for waste gas produced in polyolefin wood pellets, comprising a waste gas collection device, a primary dust removal device, a spray washing device, a secondary dust removal device, a deodorization device and a fan 90 connected in sequence.

[0038] The waste gas collection device includes a dust collection hood 10 and a conveying pipe 20, one end of the conveying pipe 20 is connected to the outlet of the dust collection hood 10, and the other end is connected to the inlet of the primary dust removal device.

[0039] The dust collection hood 10 can be provided with one or more according to the air flow rate. When there are multiple dust collection hoods, branch pipelines are designed, and each branch pipeline is collected into the main pip...

Abstract

The invention provides a treatment system of waste gas generated by polyolefin wood-plastic granulation. The treatment system comprises a waste gas collecting device, a primary dust removal device, a spraying washing device, a secondary dust removal device, a deodorization device and a fan which are sequentially communicated, wherein the waste gas collecting device is utilized for collecting waste gas, dusts with large grain diameters can be removed by the primary dust removal device, the spraying washing device is adopted for spraying and washing, water added with a surface active agent is used as an adsorbing carrier for removing dusts with small grain diameters and water-soluble organic low-molecular-weight volatile matters, drying is carried out, then the secondary dust removal device is adopted to remove fine dusts and residual water vapor, and finally, ultraviolet rays generated by the deodorization device and ozone induced by the ultraviolet rays can be used for decomposing organic low-molecular-weight volatile matters, and the exhausted gas meets the requirements. The treatment system can be used for effectively removing low-molecular-weight volatile matters, dusts, water vapor and the like in granulating waste gas, and the whole system can be used for achieving the environment-friendly and energy-saving effects completely.

Description

technical field [0001] The invention relates to a waste gas treatment system, in particular to a treatment system for waste gas produced in polyolefin wood pellets. Background technique [0002] In the production process of polyolefin wood pellets, under the action of high temperature (≤200°C) and high pressure of the flat twin extruder, the main raw material is recycled polyolefin, and plant fibers will produce a small amount of low-molecular volatiles. These low-molecular volatiles It is often accompanied by odor and is discharged together with dust and water vapor. If it is discharged directly without treatment, it will have adverse effects on human health and the surrounding environment. With the rapid expansion of the wood-plastic composite material industry and the increasing public demand for environmental quality, it is required that manufacturers must effectively treat their production waste gas before allowing it to be discharged. [0003] At present, the wood-pla...
