Embodiment Construction

[0012] The flue gas from the boiler or other industrial kilns is pulled by the induced draft fan and enters the trapping separator 6 from the smoke inlet of the venturi tube 5. In the trapping separator 6, the flue gas and the trapping column 7 The droplet separator 6 spirally rises along the swirl plate 9 to absorb the gray water droplets and SO 2 The resulting sediment is thrown out for interception, and after being trapped, it settles down to the water seal 8 for discharge. The treated flue gas descends from the inner liner column 7 to the slag removal box 4, and is then drawn by the induced draft fan to the air outlet of the slag removal box. At this time, the flue gas contains different densities of moisture, dust and flue gas, and it hits the interception plate and is intercepted. The flue gas can pass the interception plate and pass through the air outlet of the slag removal box. The flue gas processed by the slag removal box 4 has removed moisture that may cause water in t...

Abstract

The invention discloses a scum box in the fume disposal technique domain, which consists of a row of interception board and scum door, wherein the sloping angle, space and area of interception board is set according to the smoke venting quantity, temperature, speed and scum box length to prevent exhauster from liquid and dust. The invention is fixed in front of wet smoke desulfuration and dedusting system exhauster and behind the desulfuration and dedusting tower, which can be used in the pure wet smoke dedusting system to standardize the discharged smoke.

Description

Technical field [0001] The invention relates to flue gas treatment technology in the environmental protection industry, in particular to the dust removal and liquid removal equipment before the induced draft fan of the wet flue gas desulfurization and dust removal system and after the desulfurization and dust removal tower. Background technique [0002] At present, the design and manufacture of domestic wet flue gas desulfurization and dust removal systems mostly follow the provisions of the "Technical Conditions for the Certification of Environmental Protection Products in China". The main part is mostly composed of a venturi tube and a drip separator or a combination of main and auxiliary towers. After the flue gas is processed by this combined desulfurization and dust removal system, it is directly introduced to the chimney from the exhaust port through the induced draft fan. [0003] The above-mentioned wet flue gas desulfurization and dust removal treatment methods have inev...
