An energy-saving and environment-friendly dust removal, sulfur removal and smoke removal system

Abstract

The invention discloses an energy-saving and environment-friendly dust removal, desulfurization and smoke removal system. The system consists of an exhaust pipeline I, a cooling water tank, a fan, a chimney I, a recovered water tank, a water pump, an exhaust passage II, a filter I, an exhaust pipeline III, a filter II, an exhaust pipeline IV, a negative pressure vacuum air pump, an exhaust pipeline V, a filter III, a circulating water tank and a chimney II. In an application process of the energy-saving and environment-friendly dust removal, desulfurization and smoke removal system disclosed by the invention, after an exhaust gas is cooled, the hot air temperature is effectively reduced, thus prolonging the service life of the fan. Through heat transfer of a waste gas, the temperature of water in the cooling water tank reaches 70-80 DEG C, and the water can be used for showering and heating in life of people. In addition, smoke dust firstly passes through mist-like moisture to completely convert and absorb solid substances and harmful substances in the smoke dust, the gas continuously passes through the filter I, the filter II, the filter III and the circulating water tank to further deepen the purification of the gas, and the gas discharged from the chimney II has completely disappeared. Therefore, completely zero discharge of harmful substances from boiler chimneys is achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection implementation equipment, and in particular relates to an energy-saving and environment-friendly dust removal, sulfur removal and smoke removal system. Background technique [0002] Due to insufficient anticipation and poor prevention of the negative impact of highly developed industries, people have led to three global crises: resource shortage, environmental pollution, and ecological destruction. Environmental pollution refers to the natural or artificial addition of certain substances to the environment that exceeds the self-purification capacity of the environment and causes harm. Due to human factors, the composition or state of the environment changes, and the quality of the environment declines, thereby disturbing and destroying the normal production and living conditions of the ecological system and human beings. [0003] Air pollution in environmental pollution means that the conc...

Problems solved by technology

The advantage of this method is that the process is simple, no secondary pollution, low energy consumption, conducive to the diffusion of chimney exhaust, and less corrosive; the disadvantage is that the desulfurization efficiency is low, the equipment investment and floor area are large, and the technical requirements are high.

[0011] my country is a big coal country, occupying the main domestic fuel market. With the increasing demand for energy, the toxic and harmful gases produced will seriously affect the survival of human beings and the ecological environment. The dry desulfurization and dust removal currently used Due to the low efficiency of desulfurization and dust removal, the technology often fails to meet the requirements of the national "Boiler Air Pollutant Emission Standard (GB13271-2001), and the general wet desulfurization and dust removal effect is good, but the structure of the process equipment is complex and the water consumption is large, so it is difficult to get rid of the generated The problem of secondary pollution
