Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment devices, in particular to high-temperature and high-efficiency dust and saltpeter integrated equipment. Background Art

[0002] High-temperature and high-efficiency dust and nitrate integrated equipment is an integrated environmental protection equipment used for industrial flue gas pollution control. It is mainly used to simultaneously remove dust, nitrate and other harmful pollutants in flue gas, especially for those industries that produce high-temperature flue gas after combustion, such as coal-fired power plants, steel mills, cement plants, chemical plants and biomass fuel combustion. However, most of the dust and nitrate integrated equipment currently used cannot completely remove particulate matter in the flue gas, resulting in poor denitrification effect, which will have a greater impact on the environment after emission.

[0003] In response to the above problems, the "integrated dust removal, desulfurization and denitrification equipment" with Chinese publication number CN216498314U realizes the function of effectively removing particulate matter through the arrangement of a main body, a stirring mechanism, a motor, a rotating shaft, a stirring rod, a bearing, a connecting rod, adsorption cotton, a block, a buckle and a stirring blade, solves the problem that the particulate matter in the flue gas cannot be completely removed, resulting in poor denitrification and deacidification effects. Through the arrangement of a spraying assembly, a water pump, a water inlet pipe, a water tank, an infusion pipe, a water outlet pipe and an atomizing nozzle, an effective spraying function is provided for the desulfurization and denitrification agent, solving the problem that the spraying efficiency is poor during operation, thereby affecting the poor denitrification and deacidification effects.

[0004] However, this type of integrated dust and saltpeter equipment still has certain defects when in use. For example, after the adsorption cotton inside the integrated dust and saltpeter equipment is full of dust particles, it is troublesome to replace the adsorption cotton. In addition, the integrated dust and saltpeter equipment does not have a flue gas cooling function. When filtering high-temperature flue gas, the acidic components in the high-temperature flue gas are prone to form an acid dew point, resulting in condensation during the flue gas cooling process, which in turn has a strong corrosive effect on the internal structure of the equipment.

An annular fixing frame 4 is provided under the winding box b6; two winding cavities a501 are opened inside the winding box a5, an equipment cavity a502 is opened inside the winding box a5, a double-axis servo motor a503 is provided inside the equipment cavity a502, and winding wheels a701 are provided inside the two winding cavities a501; two winding cavities b601 are opened inside the winding box b6, an equipment cavity b602 is opened inside the winding box b6, a double-axis servo motor b603 is provided inside the equipment cavity b602, and winding wheels b702 are provided inside the two winding cavities b601, and adsorption cotton 7 is provided between the winding wheels a701 and b702.

[0035] Among them, a liquid storage tank 103 is provided on one side of the filter box 1, and a liquid extraction pipe 107 is connected to the top of the liquid storage tank 103, one end of the liquid extraction pipe 107 is connected to a water pump a104, one end of the water pump a104 is connected to a water outlet pipe 105, one end of the water outlet pipe 105 extends into the interior of the filter box 1 and is connected to multiple nozzles 106, an exhaust pipe is provided on one side of the filter box 1, and a liquid discharge pipe is provided on one side of the filter box 1; a limiting groove 401 is provided on the top of the annular fixed frame 4, and the bottom ends of the limiting sliders 505 extend into the limiting groove 401; both sides of the equipment cavity a502 are respectively connected to the two winding wheels a701 through rotating shafts, and one end of the two winding wheels a701 is connected to the winding box a5 through bearings, and both sides of the dual-axis servo motor b603 are respectively connected to the two winding wheels b702 through rotating shafts, and one end of the two winding wheels b702 is connected to the winding box b6 through bearings.

[0036] When in use, the high-temperature flue gas is introduced into the cooling chamber 205 inside the cooling box 2 through the smoke inlet pipe 208, and then the high-temperature flue gas is cooled by the water pump b202 and the heat-conducting copper tube 204, and the flue gas is introduced into the filter box 1 through the air inlet pipe 206. At this time, the water pump a104 is started to extract the denitrification agent inside the liquid storage tank 103, so that the denitrification agent passes through the liquid extraction pipe 107 and the water outlet pipe 105 and is sprayed out from the nozzle 106, thereby denitrifying the flue gas entering the filter box 1, and at the same time, the servo motor 102 is started, and the winding box a5, the winding box b6 and the adsorption cotton 7 are rotated by the servo motor 102, and the dust particles in the flue gas are adsorbed by the adsorption cotton 7, thereby completing the dust removal.

[0037] When the adsorbent cotton 7 is full of dust particles, the user can start the device cavity a502 and the dual-axis servo motor b603, and drive the two winding wheels a701 to rotate and roll up the adsorbent cotton 7 through the device cavity a502, and rotate the two winding wheels b702 through the dual-axis servo motor b603, so as to unfold the adsorbent cotton 7 wrapped around the winding wheels b702, and then roll up the adsorbent cotton 7 covered with dust particles, and unfold the unused part of the adsorbent cotton 7, so as to simplify the cleaning and replacement process of the adsorbent cotton 7.

[0038] Example 3

[0039] On the basis of Example 1, the cooling component includes: a water cavity 201 opened inside the cooling box 2, a cooling cavity 205 opened inside the cooling box 2, an air inlet pipe 206 is provided on one side of the cooling box 2, and one end of the air inlet pipe 206 extends into the filter box 1, an electromagnetic valve is provided on the air inlet pipe 206, a temperature sensor 207 is provided on the bottom of the inner wall of the cooling cavity 205, a water pump b202 is provided inside the water cavity 201, a water pump 203 is connected to one side of the water pump b202, and a heat-conducting copper tube 204 is connected to the top of the water pump b202; a smoke inlet pipe 208 is arranged on the top of the cooling box 2, a solenoid valve is provided on the smoke inlet pipe 208, and two cooling fans 301 are provided on one side of the heat-conducting block 3; the top end of the heat-conducting copper tube 204 passes through the cooling cavity 205 and extends into the water cavity 201, and the heat-conducting copper tube 204 located inside the cooling cavity 205 has a spiral structure.

[0040] When in use, the solenoid valves on the smoke inlet pipe 208 and the air inlet pipe 206 are opened, and the high-temperature smoke is introduced into the cooling chamber 205 through the smoke inlet pipe 208, and then the water pump b202 and the heat dissipation fan 301 are started, and the cooling water in the water chamber 201 is extracted by the water pump b202, so that the cooling water passes through the water pump 203, enters the heat-conducting copper tube 204, and then flows back to the water chamber 201. When the cooling water flows through the part of the heat-conducting copper tube 204 with a spiral structure located in the cooling chamber 205, the cooling water will absorb the heat of the smoke entering the cooling chamber 205, and The heat is brought back to the water chamber 201, and then transferred to the heat conductive block 3. At this time, the cooling fan 301 is started to dissipate the heat on the heat conductive block 3. In this process, the temperature sensor 207 inside the cooling chamber 205 senses the temperature change of the flue gas. When the flue gas drops to a suitable temperature, the temperature sensor 207 generates an electrical signal and transmits it to the control terminal, thereby shutting down the water pump b202, or adjusting the power of the water pump b202 to reduce the amount of coolant extracted, so as to keep the flue gas at a temperature suitable for the denitrification reaction.

[0041] Among them, temperature sensor 207 can be a thermistor temperature sensor with model MF52D-503-3. Temperature sensor 207 is a sensor that uses special semiconductor materials to measure temperature. The resistance value of the thermistor material inside it will increase or decrease with the change of ambient temperature, thereby changing the output power of water pump B202, thereby changing the heat generated by water pump B202. Temperature sensor 207 is a mature conventional technology in this technical field, and this solution does not make improvements to the circuit or program of temperature sensor 207. Therefore, the circuit and signal connection relationship of temperature sensor 207 will not be elaborated.

[0042] In addition, a control panel is provided on one side of the filter box 1, which can control the start and stop of the servo motor 102, the water pump a104, the water pump b202, the temperature sensor 207, the cooling fan 301, the dual-axis servo motor a503 and the dual-axis servo motor b603.

[0043] The control program involved in the present utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art, and this part is not the innovation of the present utility model.

[0044] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of ​​the present application; ordinary technicians in this field should understand that: they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
