Collection and treatment device for asphalt flue gas generated during impregnation and tank leaving

Abstract

The invention provides a collection and treatment device for asphalt flue gas generated during impregnation and tank leaving. The collection and treatment device comprises an impregnation tank, a fluegas collection pipe, a flap valve, a fixed flue gas collection hood, a support, a cooling tank flue gas branch pipe, a chain car, a cooling tank, a movable flue gas collection hood, a gap bridge, a guide rail and a movable flue gas pipe, wherein the movable flue gas collection hood collects the asphalt flue gas generated during conveying of an impregnated product from the fixed flue gas collection hood to a door of the cooling tank; a fixed flue gas collection hood branch pipeline, a movable flue gas collection hood branch pipeline and a cooling tank flue gas branch pipeline communicate through the flue gas collection pipe; the flue gas collection pipe is connected with the flap valve arranged on the movable flue gas collection hood branch pipeline; and when the movable flue gas collection hood is retracted back onto the cooling tank, the flap valve is closed. The flue gas collection pipe communicates with an electrostatic dust removal system and collects the asphalt flue gas to be purified by the electrostatic dust removal system.

Description

technical field [0001] The invention relates to the technical field of impregnation process equipment manufactured by graphite materials, in particular to an asphalt fume collection and treatment device produced during the impregnation process product is transported from the impregnation tank to the cooling tank. The device can collect and process all the asphalt fume generated during the moving process of the impregnated product, so as to ensure that there is no smoke in the on-site environment, and the collected flue gas can be discharged up to the standard after treatment. Background technique [0002] The manufacture of high-strength and high-density graphite materials requires impregnation to increase product density and strength. The impregnating agent used is generally low-quinoline-content medium-temperature asphalt. Medium-temperature asphalt will produce smoke when it is above 120°C. The impregnation process equipment is generally hot in and hot out. When the prod...

AI Technical Summary

Problems solved by technology

The impregnation process equipment is generally hot in and hot out. When the product exits the impregnation tank, the temperature reaches above 180°C. After leaving the impregnation tank, it will produce asphalt fumes during the process of hoisting it into the cooling water tank. Because it needs to be hoisted by the crane, it will be moved upside down. When the asphalt fume cannot be collected, the working environment in the workshop is poor; in order to solve the collection and treatment of the flue gas from the tank out to the cooling process, our company conducts in-depth research and analysis, and researches and designs a set of transportation and cooling methods that change the process from the tank out to the cooling process. Developed a mobile flue gas collection and treatment device for impregnation out of the tank, which collects and processes all the asphalt fume generated during the moving process of the impregnated product to ensure that there is no flue gas in the on-site environment, and the collected flue gas is discharged up to the standard after treatment
