DETAILED DESCRIPTION

[0021] In order to make the utility model embodiment's purpose, technical scheme and advantage more clear, below will combine the drawing in the utility model embodiment, clear, complete technical scheme in the embodiment is described, following embodiment is used to explain the utility model, but not to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Refer to Figures 1-5 A ceramic tubular dust collector of synchronous denitration, including support 1, ceramic cyclone body 2 is fixedly installed on support 1, ceramic air inlet pipe 201 is connected on the upper end of one side of ceramic cyclone body 2, ceramic air inlet pipe 201 is tangent to ceramic cyclone body 2, ceramic exhaust pipe 202 is inserted on the upper end of ceramic cyclone body 2, and dust discharger is installed at the dust discharging port of the bottom of ceramic cyclone body 2, further include: ceramic mixing pipe 3 is fixedly connected at the air inlet of ceramic air inlet pipe 201, gas delivery pipe 301 is fixedly connected at the air inlet of ceramic mixing pipe 3, hollow ring 304 is fixedly connected in ceramic mixing pipe 3, and the air outlet of hollow ring 304 is arranged on the side close to ceramic air inlet pipe 201, ozone generator 306 is fixedly installed on support 1, and the air outlet of ozone generator 306 is connected with hollow ring 304 through suction pipe 307, mixing mechanism for mixing dust-containing gas and ozone is installed in ceramic mixing pipe 3, lye spray tower 4 is fixedly installed on support 1, and the air outlet of ceramic exhaust pipe 202 is connected with the air inlet of lye spray tower 4 through connecting air pipe 401.

[0024] The mixing mechanism comprises a rotating shaft 302, driving blades 303 and mixing blades 305. The rotating shaft 302 is rotatably connected in the ceramic mixing pipe 3. The driving blades 303 are fixedly connected on the rotating shaft 302 at a position close to the gas conveying pipe 301 in a circumferential equidistant manner. The mixing blades 305 are fixedly connected on the end of the rotating shaft 302 penetrating the hollow ring 304 in a circumferential equidistant manner.

[0025] When it is needed to remove dust from the dust-containing gas, the synchronous denitration treatment is performed. At this time, the dust-containing gas is conveyed from the gas conveying pipe 301 into the ceramic mixing pipe 3. The high-speed flowing dust-containing gas first impacts the driving blades 303. The driving blades 303 drive the rotating shaft 302 to rotate, and then the mixing blades 305 rotate rapidly. When the dust-containing gas flows in the ceramic mixing pipe 3 and passes through the hollow ring 304, a negative pressure is formed around the hollow ring 304 due to the rapid flow of the gas. At this time, the ozone generated by the ozone generator 306 installed on the support 1 is sucked into the hollow ring 304 through the suction pipe 307 under the suction action of the negative pressure, and is sprayed out from the gas outlet on the side of the hollow ring 304 close to the ceramic gas inlet pipe 201. The ozone is fully mixed with the dust-containing gas under the stirring action of the rapidly rotating mixing blades 305.

[0026] The mixed gas enters the ceramic cyclone body 2 through the ceramic gas inlet pipe 201. Since the ceramic gas inlet pipe 201 is tangent to the ceramic cyclone body 2, the gas makes high-speed rotational motion in the ceramic cyclone body 2 after entering. According to the principle of centrifugal force, the dust particles with relatively large mass are subjected to a large centrifugal force during rotation, and are thrown to the cylinder wall of the ceramic cyclone body 2. After the dust particles collide with the cylinder wall, they lose kinetic energy and slide down the cylinder wall to the dust discharge port at the bottom under the action of gravity, and are discharged through the ash discharger, so as to realize the separation of dust and gas.

[0027] The clean gas separated from the dust by the ceramic cyclone body 2 passes through the ceramic gas outlet pipe 202 and the connecting gas pipe 401 to enter the alkali liquor spraying tower 4. The nitrogen oxides in the dust-containing gas are oxidized to high-valence nitrogen oxides when mixed with ozone in the ceramic mixing pipe 3. In the alkali liquor spraying tower 4, the oxidized nitrogen oxides react with the sprayed alkali liquor to generate soluble salts, so as to be absorbed and removed. At the same time, the sulfur dioxide contained in the gas also has the property of acidic oxidant, and can react with the alkali liquor to generate sulfite or sulfate, and then is removed from the gas.

[0028] The denitration process of the dust remover mainly includes two stages. Firstly, the ozone oxidation stage. Ozone has strong oxidizing property and can oxidize low-valence nitrogen oxides that are difficult to dissolve in water into high-valence nitrogen oxides in the flue gas. The reaction principle is based on the redox reaction, in which the oxygen atom in ozone oxidizes the nitrogen element in nitrogen oxides and is reduced itself. Then, the alkali absorption stage. The oxidized high-valence nitrogen oxides have stronger water solubility and acidity, can react with alkali, such as sodium hydroxide and calcium hydroxide, to generate nitrite and nitrate, which are dissolved in the alkali, so as to remove nitrogen oxides from the gas and achieve the purpose of denitration.

[0029] Compared with the traditional ceramic tubular dust remover that can only separate dust and cannot simultaneously remove nitrogen oxides in the dust-containing gas, the dust remover simultaneously performs dust removal and denitration, reduces the subsequent separate denitration process, simplifies the process flow, improves the processing efficiency, and further improves the comprehensive treatment capacity of pollutants, so that the exhaust gas is cleaner and more conducive to environmental protection.

[0030] Embodiment 2

[0031] With reference to Figures 1-5 A ceramic tubular dust remover for simultaneous denitration, which is basically the same as Embodiment 1, and further has the following features: the hollow ring 304 is conical, which is more conducive to the formation of negative pressure around the hollow ring 304 when the dust-containing gas flows through, so that the ozone generated by the ozone generator 306 is sucked into the hollow ring 304 through the suction pipe 307 and fully mixed with the dust-containing gas, thereby improving the denitration pretreatment effect.

[0032] The bottom of the ceramic exhaust pipe 202 is fixedly connected with a conical body 2021, a plurality of filter holes 2022 that are in communication with the ceramic exhaust pipe 202 are equidistantly formed in the conical body 2021, and the conical body 2021 and the filter holes 2022 at the bottom of the ceramic exhaust pipe 202 can perform secondary filtration on the gas entering the ceramic exhaust pipe 202, separate residual dust, improve the cleanliness of the gas, and also buffer the airflow to make the gas enter the subsequent alkali spraying tower 4 for denitration and desulfurization more smoothly.

[0033] The ceramic exhaust pipe 202 and the ceramic cyclone body 2 are detachably connected through threads, which facilitates quick separation during equipment maintenance and repair, facilitates cleaning of internal dust and replacement of worn parts, is simple to assemble, can reduce maintenance difficulty and cost, and ensures long-term stable operation of the equipment.
