Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a smoke treatment device for a thermal power plant. Background Art

[0002] Thermal power generation is a method of power generation that uses the heat energy generated by the combustion of combustibles and converts it into electrical energy through a power generation device. It mainly uses coal, oil, natural gas, etc. as fuel. Its power generation process includes fuel combustion, heat energy conversion, and mechanical energy conversion into electrical energy.

[0008] Furthermore, a vibrating hammer is fixedly connected to the left side of the movable plate, a telescopic rod is hinged between the right side of the movable plate and the front inner wall of the filter box, and a spring is sleeved on the telescopic rod.

[0009] Furthermore, the stirring mechanism includes a second motor fixedly connected to the top of the water tank, the output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling, the bottom end of the second rotating shaft extends into the interior of the water tank and is rotatably connected to the water tank, and a plurality of stirring rods are fixedly connected to the second rotating shaft.

[0012] The present invention has the following beneficial effects: (1) The present invention uses a treatment mechanism, and smoke enters the interior of the filter box through the air inlet pipe. The fan is started, and the fan sucks in the filtered smoke in the filter box through the suction pipe, and then transmits it to the coil through the air transmission pipe. The smoke in the coil is discharged into the reaction tank through the connecting pipe 1, and the smoke in the reaction tank enters the reaction tower through the connecting pipe 2. Finally, the smoke is discharged through the exhaust pipe. The heat in the smoke can be effectively recovered and utilized by the treatment mechanism to heat the water in the water storage tank, thereby improving the energy utilization efficiency of the entire system, which helps to reduce energy waste and reduce production costs. Recovering the heat in the smoke can also reduce the demand for additional energy, help reduce greenhouse gas emissions and other pollutants, and meet the environmental protection requirements of energy conservation and emission reduction. At the same time, the heat of the smoke is transferred to the water in the water storage tank, which can reduce the temperature of the smoke, which helps to reduce the heat load on subsequent smoke treatment equipment, extend the service life of the equipment, and reduce the equipment maintenance cost.

[0013] (2) The present invention uses a vibration mechanism. When the smoke enters the filter box, the dust in the smoke is filtered through the filter plate. The motor is started, and the motor drives the rotating shaft to rotate. When the rotating shaft rotates, the cam is driven to rotate. When the cam rotates, the roller is driven to move. When the roller moves, it contacts the rhombus block to make the rhombus block move. When the rhombus block moves, it drives the moving plate-fixed rod to move as the axis. When the moving plate moves, it drives the vibrating hammer away from the filter plate. When the moving plate moves, it drives the telescopic rod and the spring to contract. Through the vibration mechanism, as the filtering proceeds, the smoke particles will gradually accumulate on the filter plate. By making the filter plate vibrate, the accumulated particles can be loosened and these adhered particles can be separated from the filter plate, thereby maintaining the permeability of the filter plate, ensuring the stability of the filtering effect, and improving the filtering accuracy and efficiency. At the same time, the filter plate is kept clean by vibration, which can reduce the resistance of the smoke passing through the filter plate, reduce the operating load of equipment such as the fan, and reduce energy consumption, thereby ensuring the stable operation of the entire smoke treatment system.

[0014] (3) The present invention starts motor 2 through a stirring mechanism, and motor 2 drives shaft 2 to rotate. When shaft 2 rotates, it drives the stirring rod to rotate. When shaft 2 rotates, it drives the connecting plate to rotate. When the connecting plate rotates, it drives the sliding rod to revolve around shaft 2 as the axis. When shaft 2 revolves, it drives the supporting plate to revolve around shaft 2. When the supporting plate revolves, it drives the internal thread block to rotate on the spiral sleeve. When the spiral sleeve rotates on the internal thread block, it in turn drives the supporting plate to slide on the sliding rod, thereby driving the stirring plate to rotate around shaft 2 as the axis and slide on the sliding rod at the same time. The stirring mechanism causes water to flow, allowing water at different positions in the tank to more fully contact the coil, so that heat is more evenly transferred to the water, thereby improving the efficiency of heat exchange, accelerating the heating speed of water, avoiding the situation where the local water temperature is too high or too low, making the water temperature in the entire water storage tank more uniform, and reducing the possibility of excessively high surface temperature of the coil, which is more beneficial for protecting the coil and ensuring stable heat exchange.

Recovering the heat in the flue gas can also reduce the demand for additional energy, help reduce greenhouse gas emissions and other pollutants, and meet the environmental protection requirements of energy conservation and emission reduction. At the same time, the heat of the flue gas is transferred to the water in the water tank, which can reduce the temperature of the flue gas, which helps to reduce the heat load on subsequent flue gas treatment equipment, extend the service life of the equipment, and reduce equipment maintenance costs.

[0022] The vibration assembly includes a filter plate 31 fixedly connected to the inner wall of the filter box 21, a sealing door 32 is provided on the left side of the filter box 21, a motor 33 is fixedly connected to the top of the filter box 21, the output shaft of the motor 33 is fixedly connected to a rotating shaft 34 through a shaft coupling, the bottom end of the rotating shaft 34 extends to the inside of the filter box 21 and is rotatably connected to the filter box 21, a cam 35 is fixedly connected to the bottom end of the rotating shaft 34, a roller 36 is rotatably connected to the inner wall of the cam 35, a fixing rod 37 is fixedly connected to the inner top wall of the filter box 21, a moving plate 38 is rotatably connected to the fixing rod 37, a rhombus block 39 is fixedly connected to the left side of the moving plate 38, and a vibration hammer 33 is fixedly connected to the left side of the moving plate 38 10. A telescopic rod 311 is hinged between the right side of the movable plate 38 and the front inner wall of the filter box 21. A spring 312 is sleeved on the telescopic rod 31. Through the vibration mechanism 3, as the filtration proceeds, the smoke particles will gradually accumulate on the filter plate 31. By vibrating the filter plate 31, the accumulated particles can be loosened, and these adhered particles can be separated from the filter plate 31, thereby maintaining the permeability of the filter plate 31, ensuring the stability of the filtration effect, and improving the accuracy and efficiency of the filtration. At the same time, the filter plate 31 is kept clean by vibration, which can reduce the resistance of the smoke passing through the filter plate 31, reduce the operating load of equipment such as the fan, and reduce energy consumption, thereby ensuring the stable operation of the entire flue gas treatment system.

[0023] The stirring mechanism 4 includes a motor 41 fixedly connected to the top of the water tank 25, the output shaft of the motor 41 is fixedly connected to the rotating shaft 42 through a shaft coupling, the bottom end of the rotating shaft 42 extends to the inside of the water tank 25 and is rotatably connected to the water tank 25, a plurality of stirring rods 43 are fixedly connected to the rotating shaft 42, a protective shell 44 is fixedly connected to the inner wall of the water tank 25, a spiral sleeve 45 is fixedly connected to the inner bottom wall of the protective shell 44, an internal thread block 46 is threadedly connected to the spiral sleeve 45, a support plate 47 is fixedly connected to the outer wall of the internal thread block 46, a connecting plate 48 is fixedly connected to the rotating shaft 42, and the connecting plate 48 is fixedly connected to the inner wall of the protective shell 44. Two sliding rods 49 are fixedly connected to the bottom, and both sliding rods 49 penetrate the support plate 47 and are slidably connected to the support plate 47. A plurality of stirring plates 410 are fixedly connected to the outer wall of the support plate 47. The stirring mechanism 4 causes the water to flow, so that the water at different positions in the tank can more fully contact the coil 27, so that the heat can be transferred to the water more evenly, thereby improving the efficiency of heat exchange, accelerating the heating speed of the water, avoiding the situation where the local water temperature is too high or too low, making the water temperature in the entire water storage tank 25 more uniform, and reducing the possibility of the surface temperature of the coil 27 being too high, which is more beneficial for protecting the coil and ensuring the stable heat exchange.

[0024] When in use, smoke enters the interior of the filter box 21 through the air inlet pipe 22, and the dust particles in the smoke are filtered out by the filter plate 31, and the fan 23 is started. The fan 23 sucks the filtered smoke in the filter box 21 through the suction pipe 24, and then transmits it to the coil 27 through the air pipe 26. The circulation speed of the smoke in the water tank 25 is slowed down by the coil 27. At the same time, the smoke and the water in the water tank 25 are heat exchanged through the coil 27, and a large amount of heat energy contained in the smoke is transferred to the water in the water tank 25 through the coil 27, so that the waste heat in the smoke is fully recovered, and the energy is improved. The utilization efficiency of the resource is improved and the energy consumption is reduced. The heated water is subsequently discharged from the drain pipe 29 through the valve 210 for treatment. At the same time, new water is added to the water storage tank 25 through the water injection pipe 28. The flue gas in the coil 27 is discharged into the reaction tank 211 through the connecting pipe 1 212. The flue gas reacts with the alkaline solution in the reaction tank 211 to remove the sulfur dioxide in the flue gas. The flue gas after desulfurization enters the reaction tower 213 through the connecting pipe 214. The nitrogen oxides in the flue gas are adsorbed by the silica gel material in the reaction tower 213. Finally, the flue gas is discharged from the exhaust pipe 215.

[0025] When the smoke enters the filter box 21, the dust in the smoke is filtered through the filter plate 31 to reduce the dust particles in the smoke, thereby reducing the pollution to the atmospheric environment caused by the dust particles contained in the smoke when the smoke is discharged. At the same time, the concentration of dust particles in the smoke is effectively reduced, the risk of fire and explosion is reduced, and damage to the equipment is avoided. The dust in the filter box 21 can be cleaned through the sealing door 32, and the motor 33 is started. The motor 33 drives the shaft 34 to rotate. When the shaft 34 rotates, it drives the cam 35 to rotate. When the cam 35 rotates, it drives the roller 36 to move. When the roller 36 moves, it contacts the rhombus block 39 to make the rhombus block 39 move. When the rhombus block 39 moves, it drives The movable plate 38 and the fixed rod 37 move axially. When the movable plate 38 moves, the vibrating hammer 310 is driven away from the filter plate 31. When the movable plate 38 moves, the telescopic rod 311 and the spring 312 are contracted. When the roller 36 is not in contact with the rhombus block 39, the spring 312 is reset, thereby driving the telescopic rod 311 to stretch. When the telescopic rod 311 is stretched, it drives the movable plate 38 to move, thereby causing the vibrating hammer 310 to impact the filter plate 31 to vibrate. By vibrating the filter plate 31, the dust attached to the filter plate 31 can be loosened and fallen off, thereby preventing the filter holes on the filter plate 31 from being blocked and keeping the filter channel unobstructed, thereby improving the passing efficiency of the smoke and enhancing the filtering effect of the filter plate 31.

[0026] Start the second motor 41, the second motor 41 drives the second shaft 42 to rotate, and the second shaft 42 drives the stirring rod 43 to rotate when the second shaft 42 rotates. The stirring rod 43 stirs the water in the water storage tank 25, improves the fluidity of the water in the water storage tank 25, reduces the thermal resistance between the water and the pipe surface, makes it easier for heat to be transferred from the pipe to the water, and improves the efficiency of heat transfer. When the second shaft 42 rotates, it drives the connecting plate 48 to rotate. When the connecting plate 48 rotates, it drives the sliding bar 49 to revolve around the second shaft 42 as the axis. When the second shaft 42 revolves, it drives the support plate 47 to revolve around the second shaft 42. When the support plate 47 revolves, it drives the internal thread block 46 to rotate in the screw thread. The spiral sleeve 45 rotates on the internal thread block 46, which in turn drives the support plate 47 to slide on the slide bar 49, thereby driving the stirring plate 410 to rotate around the rotating shaft 42 as the axis while sliding on the slide bar 49, further enhancing the fluidity of the water in the water storage tank 25, so that the bottom water and the upper water in the water storage tank 25 are replaced, which can better transfer heat to various parts of the water, avoid local overheating or overcooling, and make the water temperature more uniform, thereby improving the uniformity and efficiency of heating, so as to achieve a better stirring effect in the same time, shorten the stirring time, and then shorten the heating time.
