Dust exhaust gas purification tower

Abstract

The invention discloses a dust exhaust gas purification tower. A water storage tank, a water wall purification module, a water-vapor convection purification module, a smoke gas transfer box and a purification pool are sequentially arranged inside the tower body from top to bottom, wherein a straight notch is formed in the bottom of the water storage tank along the diameter direction; a valve is arranged at the notch; the water wall purification module comprises a gas guide plate A and a gas guide plate B; the tilting gas guide plates A and B are alternatively and sequentially arranged vertically downwards from one side of the notch; the tilting gas guide plates B and A are alternatively and sequentially arranged vertically downwards from the other side of the notch; the bottom sides of the gas guide plates A and B and the side of the corresponding notch are positioned on the same vertical surface; two sides of the gas guide plates A and B are connected with the inner wall of the purification tower in a sealed manner; a gap is formed between the top side of the gas guide plate A and the inner wall of the purification tower; the top side of the gas guide plate B is connected with the inner wall of the purification tower in a sealed manner; the water-vapor convection purification module is of a periphery down-dip structure; the smoke gas transfer box is connected with a smoke gas inlet; a gas guide pipe is arranged on the bottom surface. Composite smoke prevention, dust control and sulfur removal can be achieved, and the purification effect is improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a soot and waste gas purification tower, which is mainly used in the aspects of smoke elimination, dust removal, desulfurization and waste gas treatment of oil-fired gas-fired coal-fired boilers. Background technique [0002] With the rapid development of modern industry, it has become the basic national policy of our country to improve the purification effect of smoke elimination, dust removal and desulfurization equipment, strengthen waste gas treatment, strictly implement the regulations on gas emission after reaching the standard, and realize environmental protection. The existing smoke elimination, dust removal and desulfurization equipment And waste gas treatment is mainly based on electronic dust removal, bag dust removal, dry dust removal, and wet dust removal. Among them, spray, spray, and wet dust removal are the most commonly used equipment in smoke elimination, ...

Problems solved by technology

[0002] With the rapid development of modern industry, it has become the basic national policy of our country to improve the purification effect of smoke elimination, dust removal and desulfurization equipment, strengthen waste gas treatment, strictly implement the regulations on gas emission after reaching the standard, and realize environmental protection. The existing smoke elimination, dust removal and desulfurization equipment And waste gas treatment is mainly based on electronic dust removal, bag dust removal, dry dust removal, and wet dust removal. Among them, spray, spray, and wet dust removal are the most commonly used equipment in smoke elimination, dust removal and desulfurization, and are generally valued by people. , Various wet smoke and dust removal and desulfurization devices developed in China generally have low smoke and dust removal efficiency, low desulfurization efficiency, equipment corrosion, serious blockage, backward technology for carrying water in flue gas, unreliable operation of equipment, and high investment costs. series of questions

[0003] The above problems greatly affect the actual effect of smoke elimination, dust removal, desulfurization and waste gas treatment. In addition to spraying, spraying, and wet methods, the environmental protection community has not yet found a new water carrier to more effectively eliminate smoke, dust, desulfurization and waste gas treatment.
