Flue gas dust removing and denitration device

Abstract

The invention discloses a flue gas dust removing and denitration device. The flue gas dust removing and denitration device comprises a dust removing bin, a dust removing cloth bag, a denitration chamber, a denitration catalyst bed layer and a gas absorber, the dust removing cloth bag is arranged inside the dust removing bin, the top of the dust removing cloth bag is connected with the top of the dust removing bin, the denitration chamber is arranged at the upper end of the dust removing bin, the internal space of the dust removing cloth bag is communicated with the denitration chamber, the denitration catalyst bed layer is horizontally arranged inside the denitration chamber, the internal space of the denitration chamber is divided into two parts, and the gas absorber is connected with the top of the denitration chamber through a gas suction pipe and is communicated with the internal space of the denitration chamber. The flue gas removing and denitration device is simple and novel in structure, low in cost, high in dust removing and denitration speed and good in dust removing and denitration effect.

Description

technical field [0001] The invention relates to an environment purification device, in particular to a flue gas dust removal and denitrification device. Background technique [0002] Coal-fired boilers are widely used. Coal-fired boilers will produce a lot of flue gas when they are in use, and the particles, sulfur-containing compounds and nitrogen-containing compounds contained in the flue gas are all substances that pollute the atmosphere. Coal-fired boilers The problem of smoke and dust has always troubled these people. With the development of the economy, people have higher and higher requirements for environmental protection, and the smoke and dust problem of coal-fired boilers has become more and more prominent. In order to solve the above problems, people have continuously developed new products, but now the general wet treatment method, in the After passing through the spray layer, it will still carry a large amount of mist particles and particulate matter.

Problems solved by technology

With the development of the economy, people have higher and higher requirements for environmental protection, and the smoke and dust problem of coal-fired boilers has become more and more prominent. In order to solve the above problems, people have continuously developed new products, but now the general wet treatment method, in the After passing through the spray layer, it will still carry a large amount of mist particles and particulate matter. If there are too many particles in the flue gas, it will affect the demisting effect in the flue gas treatment, and ultimately affect the desulfurization and denitrification efficiency of the device. Therefore, it is urgently needed now. A new type of flue gas desulfurization, denitrification and dust removal device to solve the above problems
