Description

TECHNICAL FIELD

[0001] The utility model relates to desulfurization and denitration dust removal technical field, more specifically, it relates to a desulfurization and denitration dust removal device. BACKGROUND

[0002] The flue gas produced in the processes of coal-fired power plants, industrial production and waste gas treatment often contains a large amount of harmful substances such as sulfur oxides, nitrogen oxides and particulate matter, which seriously affects the environment and human health. Therefore, the development of efficient and reliable desulfurization and denitration dust removal devices has become an important task in the current environmental protection field. Currently, some emerging desulfurization and denitration dust removal technologies have received widespread attention. For example, dry desulfurization technology uses new adsorbents to efficiently remove sulfur oxides from flue gas; selective non-catalytic reduction (SNCR) technology uses non-catalytic reducing agents to reduce nitrogen oxide emissions; pulse jet dust removal technology uses airflow and jet technology to efficiently remove particulate matter;

[0003] Referring to patent publication number CN218339428U, a desulfurization and denitration dust removal device is proposed, which mainly proposes that the traditional desulfurization and denitration device is complex, large in size, consumes a large amount of water, has high one-time investment, and the liquid or sludge after treatment is difficult to handle. In addition, during the desulfurization and denitration reaction process, the pressure changes, which may cause the phenomenon of flue gas backflow, affecting the entire process, or even causing insufficient flue gas treatment and environmental pollution;

[0004] However, we found that the device has some problems in use, such as the device is used for a long time, the inner wall top is directly affected by the temperature difference of the external temperature, which can easily cause corrosion of the top during long-term use, and the discharged flue gas is also easy to cause corrosion of the storage tank. After long-term use of both places, it is very troublesome to clean up, therefore, we design a desulfurization and denitration dust removal device with long service life. Utility model content

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A desulfurization and denitration dust removal device, comprising a reaction box body, a retention and reheating plate is arranged on the top of the reaction box body, a heating pipe is arranged on the top of the retention and reheating plate, a warm fan is arranged on the bottom of the reaction box body, a protective seal is arranged on the top of the reaction box body, the protective seal is embedded and installed in the inside of the retention and reheating plate, limit clamping blocks are arranged on the two sides of the protective seal, and a filter retention plate is arranged on the top of the protective seal.

[0007] Further, the top of the filter retention plate is provided with a flow pipe, one end of the flow pipe is provided with a condenser, and the condenser is arranged to condense the filter flowing through the flow pipe.

[0008] Further, the bottom of the condenser is provided with a convection air box, one side of the convection air box is provided with a hinge, and the convection air box is fixedly connected with the surface of the reaction box through the hinge.

[0009] Further, the bottom of the convection air box is provided with a storage tank, the storage tank is fixedly connected with the flow pipe and the convection air box, the hinge is also arranged on the surface of the storage tank, and the storage tank is fixedly connected with the surface of the reaction box through the hinge.

[0010] Further, the inside of the storage tank is provided with a rotating blade, the top of the storage tank is provided with a one-way pipe, and the top of the storage tank is embeddedly connected with a sealing plug.

[0011] Further, the inside of the filter retention plate is provided with a filter screen, and the surface of the filter screen is provided with a clamping plate.

[0012] In summary, the utility model has the following beneficial effects:

[0013] By arranging the filter retention plate, the flow pipe, the condenser and other mechanisms, the inner cavity top of the reaction box can be reduced in corrosion during use, so that the dust removal efficiency is improved, and the dust removal process is changed from cleaning and removing to slightly sweeping and disassembling, thereby fundamentally solving the problem that the existing device is too complex to clean and remove dust.
