Stack gas desulfurizing and dedusting apparatus

Abstract

The invention relates to a fume desulfurizing and dust-cleaning device mainly used in industrial fume purification, and its reaction main body includes several parallel or serial reaction components, each of which has a spray head-inserted diffuse pipe at the upper end and connects in series with several reaction main parts, in the shell of each reaction main part, there is a hammer body on the top and a converter ring at the bottom, where the top and bottom surfaces of the hammer body protrude upwards or downwards, respectively, there is a gap left between the outer edge and the shell, there is a throat formed by the side wall protruding inwards in the middle part of the converter ring, the top and bottom side walls smoothly expand and hermetically connect with the inner wall of the shell. When it is used, the fume enters the reaction components from the upper end, is firstly sprayed by alkali absorption liquid and then goes through two water curtains and multiple deflection and speed change in each reaction main part, so as to make smoke dust and SO2 enter into the absorption liquid. It can be completely made of corrosion-resistant, wearable, temperature-resistant modified material, and has advantages of high purifying efficiency, long service life, non-corroding and convenient installation, operation and use.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a flue gas desulfurization dust collector mainly suitable for industrial flue gas purification. Background technique [0002] There are many kinds of desulfurization and dust removal equipment for industrial flue gas, among which the wet method equipment is widely used due to the advantages of low investment and low operating cost. Bubble type, rotating water film type and other structural forms, the main defect is that the equipment structures in these forms are relatively complicated, especially due to structural constraints, the main components need to be made of metal materials, due to the commonly used carbon steel The anti-corrosion performance is poor, and there has never been a fundamental breakthrough in surface anti-corrosion technology, so that the service life of equipment made of carbon steel is very short; The lifespan is not long; if titanium steel and other s...

[0002] There are many kinds of desulfurization and dust removal equipment for industrial flue gas, among which the wet method equipment is widely used due to the advantages of low investment and low operating cost. Bubble type, rotating water film type and other structural forms, the main defect is that the equipment structures in these forms are relatively complicated, especially due to structural constraints, the main components need to be made of metal materials, due to the commonly used carbon steel The anti-corrosion performance is poor, and there has never been a fundamental breakthrough in surface anti-corrosion technology, so that the service life of equipment made of carbon steel is very short; The lifespan is not long; if titanium steel and other steels with high anti-corrosion and wear resistance are used instead, the price is very expensive, which exceeds the affordability of users; therefore, these desulfurization and dust removal equipment are severely restricted in practice, which affects the pollution of flue gas sulfur dioxide control
