Description

Technical Field

[0001] The present invention relates to the technical field of rubber processing, in particular to an integrated treatment device for desulfurization, denitration and dust treatment of waste gas from a thermoelectric power plant. Background Art

[0002] Thermal power plant exhaust gases primarily originate from boiler combustion and chimney emissions. These gases contain large amounts of harmful substances such as sulfur dioxide, nitrogen oxides, and dust, severely impacting air quality and human health. Exhaust gas desulfurization primarily utilizes wet limestone desulfurization technology, where limestone slurry reacts with sulfur dioxide in the flue gas to produce calcium sulfite, which is then oxidized to gypsum, achieving desulfurization. Denitrification primarily utilizes selective catalytic reduction technology, where a reducing agent such as ammonia is injected to react with nitrogen oxides in the flue gas to produce nitrogen and water, achieving denitrification. Dust removal primarily utilizes electrostatic precipitators (ESPs) or bag filters, removing dust from the flue gas through electrostatic forces or filtration.

[0003] When the existing integrated desulfurization, denitrification and dust treatment equipment of thermal power plants is in use, such as application number CN202122492558.4, which discloses a power plant coal boiler combustion exhaust gas purification treatment equipment, the equipment comprises a box body and a filtering mechanism; a filtering mechanism is arranged in an array inside the box body, a separation mechanism is arranged at the bottom of the box body, and the separation mechanism is connected to the water supply mechanism through a connecting pipe; a spraying mechanism arranged at the top of the water supply mechanism is arranged on the box body; the separation mechanism arranged at the bottom of the box body performs sewage separation, and cooperates with the water pump arranged in the water supply mechanism to pump the separated water into the water supply machine In the structure, the spraying mechanism arranged at the top of the water supply mechanism sprays water into the box to complete the circulation treatment, and the particulate matter present in the gas is adsorbed by the water, and the water with adsorbed particles flows into the separation mechanism for separation, and the separated water is pumped into the water supply mechanism by cooperating with the water pump arranged in the water supply mechanism.

After adsorption, the wastewater is input into the sewage purification cabin 506 for temporary storage, and finally discharged by opening the drain valve block 507.

[0044] The working principle of the present invention is as follows: when in use, the device is placed at the device's use location by means of the pad 101 in conjunction with the base 102, and the various components of the device are spliced ​​and assembled by bolting the frame 103, the arc-shaped base top 104 and the arc-shaped matching plate 105. When it is needed to be used, the first air valve 206 is opened, and after opening, the first fan 205 outputs power to drive the output end to operate. The output operation of the power output of the first fan 205 causes the polluted exhaust gas to pass through the first connecting pipe 204, the first fan 205 and the first air valve 206 to be input into the interior of the dust removal cabin 201. When the polluted exhaust gas is input into the interior of the dust removal cabin 201, the annular pipe 3 02. The annular fin 303 effectively absorbs the heat of the exhaust gas. After absorption, the exhaust heat is output to the branch pipe 305 and the parallel fin 306 through the through-tube 301 and the end outlet pipe 304 to achieve the absorption and discharge of the exhaust heat, which can effectively improve the safety of the equipment. The cooled exhaust gas passes through the binding port 404 below the bolt hole plate 402 and contacts the non-woven cover 405, so that the dust particles in the exhaust gas are intercepted. After interception, the logistics is transmitted to the top output of the bolt hole plate 402. When the exhaust gas reaches the dust removal, the second air valve 501 is opened. After the second air valve 501 is opened, the second fan 502 outputs power to drive the output end to operate, so that the exhaust gas passes through the second connection After the transfer of pipe 503, node cabin 504, and second bolt bottom plate 505, it is input into sulfur nitrate separation cabin 601. When water adsorption is needed, the water inlet valve block 701 is used to open it. After opening the water inlet valve block 701, the water pump 702 outputs power to drive the output end to operate. After the water pump 702 outputs power, the water inlet 703, water separation seat 704 and atomizing nozzle 705 input water to achieve the effect of atomizing injection, so that the atomized water can absorb the soluble substances in the exhaust gas. After adsorption, the wastewater is input into the sewage purification cabin 506 for temporary storage, and finally discharged by opening the drain valve block 507. Then, the output end of the drive motor 6018 is used to output power to drive the output. The output end is operated, so that the output end of the driving motor 6018 drives the active gear 6017 to operate after operation, so that when the gear ring 6016 cooperates, the wheel frame 609 rotates the perforated plate 6010 and the upper plate 6013 at a high speed on the inner side of the second annular base 607. During the rotation, the adsorption rod 6015 on the inner side of the sleeve 6014 can fully achieve the effect of desulfurization and denitrification of the exhaust gas. The exhaust gas after denitrification and desulfurization is input to the top of the sulfur-nitrate separation cabin 601 through the perforated plate 6010 and the upper plate 6013, and then the exhaust fans 606 at both ends of the split cabin 604 are used to output power to drive the output end to operate, so as to discharge the treated exhaust gas and complete the treatment process.
