No-smoke environment-friendly and energy-saving funnel

Abstract

The invention discloses a no-smoke environment-friendly and energy-saving funnel. The no-smoke environment-friendly and energy-saving funnel is characterized in that an air-removed sewage pool and an air-removed pure water pool are two closed cuboid spaces clinging to each other, and a smoke exhaust pipeline connected with a boiler communicates with the air-removed sewage pool through a smoke prevention and dust control device; the smoke exhaust pipeline comprises a plurality of insulated pipes which communicate in sequence, and a plurality of layers of transversely staggered and sequentially communicating heat absorbing water pipes are arranged in each insulated pipe in the length direction to absorb heat in exhaust gas of the boiler; and the smoke prevention and dust control device comprises a plurality of smoke prevention sheets arranged on a central upright in a sleeving manner, a plurality of round holes distributed in the circumferential direction are formed in each smoke prevention sheet, and the round holes in every two adjacent smoke prevention sheets are mutually staggered, so that smoke sedimentation and exhaust gas separation are guaranteed. According to the no-smoke environment-friendly and energy-saving funnel, energy of exhaust gas of the boiler is re-utilized through the heat absorbing water pipes, meanwhile, the leakproofness and the thoroughness of smoke prevention and dust control are guaranteed, and therefore, the no-smoke environment-friendly and energy-saving funnel is energy-saving and environment-friendly, long in service life and convenient to use and maintain.

Description

technical field [0001] The invention relates to a dust-free, environment-friendly and energy-saving chimney device, which is suitable for the flue gas purification treatment of large boilers. Background technique [0002] In recent years, the living environment of human beings has been seriously damaged, especially the increasing air pollution, including the increasingly frequent smog weather phenomenon, which poses a great threat to people's travel safety and health. There are many factors that lead to air pollution. Among them, the gas emissions from boiler combustion have a great impact on environmental damage, and the resulting boiler flue gas purification equipment is also emerging in endlessly. [0003] At present, there are mainly two types of boiler flue gas purification equipment, one is electrostatic dust removal, and the other is water curtain dust removal. Electrostatic dust removal is suitable for factory workshops with small dust, with low dust removal ability...

AI Technical Summary

Problems solved by technology

Electrostatic dust removal is suitable for factory workshops with small dust, with low dust removal ability and large investment; water curtain dust removal is suitable for flue gas dust removal in chimneys, but due to its non-tightness, it cannot completely remove the smoke generated by boiler combustion. The exhausted flue gas does not meet the national environmental protection requirements, and the service life is not long

Moreover, the flue gas produced by boiler combustion still contains a large amount of heat, and a large amount of white mist is often generated after contacting with the air. The existing boiler flue gas purification equipment cannot reuse the heat contained in the boiler flue gas, thus losing most of the energy

In addition, too fast smoke exhaust speed will often bring the tiny particles missed in the smoke into the air, which will cause environmental pollution
