Description

Odor gas treatment equipment and treatment method for HDPE plastic pipe production line

technical field

The invention belongs to the field of extruding and granulating peculiar smell gas of HDPE regenerated materials, in particular to a kind of peculiar smell gas treatment equipment used in HDPE plastic pipe production line.

technical background

With the increase in the price of plastic raw materials, various manufacturers have adopted various methods to reduce production costs, especially in the field of HDPE plastic pipe production, adding a large amount of fillers and recycled materials to the production raw materials. However, the production of recycled materials is accompanied by a large number of Odor gas affects the health of employees and causes environmental pollution. The treatment of odor gas has become a problem that cannot be ignored.

At present, the main methods of odor gas treatment include absorption method, adsorption method, microbial method, plasma method and dry neutralization method, etc. These methods are suitable for various odor gas treatment. The peculiar smell produced in the plastic production process usually adopts a single activated carbon adsorption method, absorption method or dry neutralization method. There is no mature treatment method for extrusion granulation of HDPE recycled materials.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a novel HDPE regenerated material extrusion granulation odor gas treatment equipment.

Another object of the present invention is to provide a treatment method, which combines activated carbon adsorption method, absorption method and dry neutralization method to control the odorous gas of HDPE recycled material extrusion granulation.

In order to realize the above-mentioned purpose of the invention, the technical scheme adopted is as follows:

A kind of odor gas treatment equipment for HDPE plastic pipe production line, including gas collecting pipe, said gas collecting pipe is connected to the end of the pipe collection system of HDPE plastic pipe production line, said gas collecting pipe is provided with adsorption net and spray water tower in sequence and gas purification equipment.

The adsorption net adopts an activated carbon adsorption net, and the activated carbon adsorption net is arranged at the front end of the air collecting pipe, and the thickness of the activated carbon adsorption net is 3-5 mm.

The activated carbon adsorption net is provided with grooves with a depth of 2-4mm.

A deodorant is added to the water in the spray water tower.

The gas purification equipment is provided with a deodorizing membrane.

The gas collecting pipe is also equipped with a centrifugal fan after the gas purification equipment.

The end of the air collecting pipe is provided with a high-altitude discharge cylinder.

In order to realize the second invention object, the technical scheme adopted is as follows:

A method for treating peculiar smell gas, comprising the steps of:

1) At the end of the pipeline collection system of the HDPE plastic pipeline production line, the impurities with larger particles in the odorous gas are removed by setting an adsorption net;

2) The odorous gas treated by the adsorption net is then sprayed through the spray water tower to remove water vapor and small particles in the odorous gas;

3) The odorous gas after spraying is further purified by gas purification equipment.

After step 3), the treated gas is discharged through a centrifugal fan.

The present invention first designs a suitable odor gas pipeline collection system according to the machine layout of the granulation workshop, and its function is to collect particles, flocs, dust, etc. in the waste gas, and optimize the production environment of the workshop. In the present invention, an activated carbon adsorption net is placed at the end of the pipeline collection system, that is, the discharge outlet. The main function is to remove impurities with relatively large particles in the odorous gas, and to isolate smaller particles through the activated carbon adsorption net. The odorous gas treated by the activated carbon adsorption net is then passed through the spray water tower with deodorant added to remove the water vapor and smaller particles in the odorous gas. The odorous gas passing through the spray water tower is then added to the air duct through the deodorant released by the deodorizing membrane in the gas purification equipment, and the treated gas is discharged by the centrifugal fan. So as to achieve the purpose of HDPE recycled material extrusion granulation odor gas treatment.
