Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] An energy-saving water mist dedusting system is disclosed in the embodiment. Through structural design, the system comprehensively utilizes the principles of centrifugal separation and water mist dedusting, adopts hierarchical settings, and is respectively equipped with a centrifugal separation device, a water mist dedusting device, and a demisting device. Humid (saturated), high temperature (not higher than 130°C) gas flows through each area in turn, and the large particles and fine particles of dust in the gas are sequentially removed under the action of different principles of gravity centrifugal separation, water film dust removal, and folding plate defogging. and moisture, to achieve a dust removal rate of more than 99% in high-temperature, high-humidity dusty gas, and clean and thorough separation of dust, gas, and water. The syste...

Abstract

The invention discloses a water mist dust removal system which comprises a centrifugal separation device, a water mist dust removal device and a mist removal device in hierarchical arrangement, wherein high-humidity and high-temperature gas flows through various areas in turn; through the structural design of a guide cylinder, a water distributor, a high-pressure extremely fine nozzle, a guide plate, a demister and the like in the device and under the actions of different principles of the areas, large-particle dust, fine-particle dust and moisture in the gas are removed sequentially; effective dust removal and cooling are performed on the high-humidity and high-temperature dust-containing gas; the dust removal rate can reach 99% or more. Furthermore, the system also can be integrated with a water purifying and circulating device; through the water purifying and circulating device, overflow water of the water mist dust removal device and the demisting device is purified; the purified water flows into the centrifugal separation device and the water mist dust removal device to realize recycling of the water, thereby greatly reducing the usage amount of the dust removal water and lowering the operation cost.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and treatment, and in particular relates to a water mist dedusting system applied to effectively remove dust in high-humidity (saturated) and high-temperature (not higher than 130°C) gas. Background technique [0002] In recent years, with the rapid development of the economy, the air pollutants emitted by industrial furnaces have caused great harm to the surrounding environment, so the technology of removing particulate matter from dusty gas to reduce its emission to the atmosphere has become more and more important. [0003] Due to the limitation of my country's energy endowment conditions, coal has always been the main primary energy source in my country. This coal-based energy structure determines that carbon dioxide, sulfur dioxide, smoke, dust, etc. produced by coal combustion are important causes of air pollution in our country. factor. At the same time, the rapid developme...
