Problems solved by technology

[0003] The existing desulfurization, denitrification and dust removal equipment still has certain disadvantages in use. For example, when multiple desulfurization towers are connected in series with the denitrification tower, the floor area is too large, and the maintenance cost is high, which limits its use. At the same time, this type of desulfurization tower The denitrification and dust removal integrated equipment usually has a weak dust removal effect, and the catalyst in the denitrification zone is affected by the clogging of fly ash during the contact process with the flue gas, which will accelerate the gradual decrease of its activity, thereby reducing the treatment effect of the denitrification zone and increasing the operating cost

Abstract

The invention relates to desulfurization, denitrification and dust removal integrated equipment for industrial waste gas. The equipment comprises a gas inlet mechanism, a filtering mechanism and a gas exhaust mechanism which are sequentially arranged from bottom to top and communicate with one another, wherein the air inlet mechanism comprises a water storage tank as well as an air inlet device and a spraying device which are arranged in the water storage tank; the filtering mechanism comprises a filtering shell, an air extractor mounted on the filtering shell, and a primary filtering device and a secondary filtering device which are mounted in the filtering shell; the secondary filtering device is mounted in the primary filtering device; the exhaust mechanism is mounted on the filtering mechanism and comprises a catalytic device and a catalytic filtering device which are arranged in sequence. During dust removal, waste gas sequentially passes through the gas inlet device, the spraying device, the primary filtering device and the secondary filtering device for dust removal, then enters the catalytic device for denitration catalysis, is filtered by the catalytic filtering device and then is discharged. The equipment performs spraying dust removal, twice filtration and then the catalytic reaction, and is good in dust removal effect and low in operation cost.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to an integrated device for desulfurization, denitrification and dust removal of industrial waste gas. Background technique [0002] Combined flue gas desulfurization, denitrification and dust removal is a new type of flue gas purification technology that has been developed and developed at home and abroad in recent years. Promote the value of a new generation of flue gas purification technology. [0003] The existing desulfurization, denitrification and dust removal equipment still has certain disadvantages in use. For example, when multiple desulfurization towers are connected in series with the denitrification tower, the floor area is too large, and the maintenance cost is high, which limits its use. At the same time, this type of desulfurization The denitrification and dust removal integrated equipment usually has a weak dust removal effect, and the catalyst in the denitrif...
