Smoke collecting and processing device for plastic sheet die head and working method of smoke collecting and processing device

Abstract

The invention discloses a smoke collecting and processing device for a plastic sheet die head. The smoke collecting and processing device comprises the plastic sheet die head, a plastic sheet, a water tank, a sealing cover, a gas outlet pipe, an activated carbon treatment tank, a water ring vacuum pump, a tubular cooler, a gas-liquid separator and a tail gas treatment box; the plastic sheet die head is installed on the top of the water tank, the sealing cover is arranged on the top of the water tank, the plastic sheet is extruded out of the output end of the plastic sheet die head, and the air outlet pipe is arranged on the top face of the water tank; the water tank is connected to the activated carbon treatment tank through the air outlet pipe, and the activated carbon treatment tank is connected to the tubular cooler through the water ring vacuum pump; the exhaust end of the tubular cooler is connected to the gas inlet end of the gas-liquid separator; and the exhaust end of the gas-liquid separator is connected to the tail gas treatment box. The smoke treatment device is simple in structure, convenient and fast; the energy consumption is low; and circulating water is adopted, so that secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of plastic sheets, in particular to a device for collecting and processing smoke from a plastic sheet die head and a working method thereof. Background technique [0002] Plastic packaging sheets are mainly used to produce thermoformed products such as disposable plastic cups, plates, bowls, plates, boxes, etc., and are widely used in the packaging of food, vegetables, fruits, beverages, dairy products, industrial parts and other fields. With the increasing domestic demand, the use of packaging plastic thermoforming sheets is becoming more and more extensive, and the consumption is also increasing year by year. The prospect is promising. [0003] The traditional smoke treatment scheme adopts the collection of smoke hood and the centralized treatment of smoke pipe transportation; the traditional smoke treatment scheme cannot solve the problems of smoke drift, smoke deposition inside the pipeline, energy consu...
