Environment-friendly industrial flue gas pipeline and application method thereof

Abstract

The invention relates to the technical field of industrial flue gas emission, in particular to an environment-friendly industrial flue gas pipeline. The invention aims to solve the technical problems that the utilization rate of coke particle combustion heat and the utilization rate of flue gas waste heat are low, a large amount of heat is wasted, and an impurity accumulation layer on the inner wall is difficult to clean. In order to solve the technical problems, the environment-friendly industrial flue gas pipeline provided by the invention is composed of a boiler, a water tank, a support mechanism, an ash scraping mechanism and a worm gear mechanism. Coke particles are filtered out in the boiler and are fully combusted in a filter plate, and heat in the boiler is increased, so that the heat can be more fully utilized, energy waste is reduced, and the cost is reduced; through a metal exhaust pipe and a surrounding metal water pipe, water in a water inlet pipe can be preliminarily heated through preheating of a flue gas in the exhaust pipe, so that the energy utilization rate is increased; and the flue gas is cooled, and the heat emitted to the environment is reduced, so that the environment is protected.

Description

technical field [0001] The invention relates to the field of industrial flue gas discharge, in particular to an environment-friendly industrial flue gas pipeline and its use method. Background technique [0002] When the industrial boiler is working, the exhaust gas is discharged through the chimney, and the exhaust gas contains a large amount of dust and other harmful gases, especially when the combustion is insufficient, the billowing black smoke discharged is the coke particles of insufficient combustion, which contain a large amount of dust, particles If the gas is directly discharged into the environment, it will cause great harm to the environment. [0003] The existing patent (notification number: CN105042609B) discloses a purification device for exhaust gas emitted from industrial chimneys. The device can improve the purification effect, and can fully burn coke particles, purify the flue gas, and improve the purification efficiency and work efficiency. . In the pro...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an environment-friendly industrial flue gas pipeline and its use method, which solves the problem of low utilization rate of coke particle combustion value and waste heat of flue gas in the existing environment-friendly industrial flue gas pipeline. The utilization rate is low, causing a large amount of heat to be dissipated into the environment and wasted, and the impurity accumulation layer on the inner wall is difficult to clean up.
