Description

Technical Field

The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two major parts: pot and furnace.

[0031] The working principle of the boiler flue gas integrated treatment system disclosed in the present invention is as follows: first, the mounting base 103 is installed on the boiler exhaust port. When the flue gas enters the heat absorption chamber 101, part of the heat in the flue gas will be absorbed by the heat absorption sheet 102. The heat absorption sheet 102 transfers the temperature to the heat absorption chamber 101. A temperature difference will be generated at both ends of the power generation diode on the power generation component 116. At this time, the heat energy of the heat absorption chamber 101 can be converted into electrical energy for utilization. At the same time, the top drive motor 206 and the bottom drive motor 209 need to be started. The output shafts of the top drive motor 206 and the bottom drive motor 209 are respectively The top driving gear 207 and the bottom driving gear 208 are driven to rotate respectively, and the top driving gear 207 and the bottom driving gear 208 drive the top executing gear 212 and the bottom executing gear 213 to rotate respectively through the top intermediate gear 210 and the bottom intermediate gear 211, and the top executing gear 212 and the bottom executing gear 213 will respectively drive the second boosting fan 215 and the first boosting fan 214 to rotate, thereby driving the smoke flow in the installation cylinder 216. When the smoke moves to the spiral nozzle 203, since the spiral nozzle 203 is spirally arranged, the smoke ejected from the spiral nozzle 203 will spirally rotate. The smoke turns upward. At this time, the solid particles in the smoke will be pulled to the inner wall surface of the centrifugal cylinder 201 because there is no other force to offset the centrifugal force generated by the high-speed rotation. At this time, the solid particles in the smoke at the axis position of the centrifugal cylinder 201 are less than the solid particles far away from the axis of the centrifugal cylinder 201. At this time, the smoke in the middle will pass through the conical cover 217 and enter the turbine sleeve 114, while the smoke on the outside will enter the diverter cover 303. At the same time, the smoking motor 305 is started, and the smoking motor 305 drives the smoking fan 310 to rotate, and generates a pressure difference to suck the smoke in the diverter cover 303. To the primary air intake pipe 306, the flue gas in the primary air intake pipe 306 will be discharged into the head purification box 307. It should be noted that the head purification box 307 is provided with a calcium hydroxide solution for absorbing carbon dioxide gas in the flue gas and reducing the temperature of the flue gas. Then the calcium hydroxide solution will generate bubbles to discharge the undissolved gas, which is then discharged into the tail purification box 302 through the terminal air intake pipe 309. The tail purification box 302 is provided with a sodium hydroxide solution for absorbing sulfur dioxide gas in the flue gas and further reducing the temperature of the flue gas, and is discharged outward through the exhaust pipe 301. A purification component can be installed on the exhaust pipe 115 as needed to purify the flue gas discharged from the exhaust pipe 115.At the same time, the flue gas discharged upward in the turbine sleeve 114 will drive the turbine 113 to rotate, and the turbine 113 drives the linkage rod 111 to rotate through the second belt transmission mechanism 112, and the linkage rod 111 drives the first belt transmission mechanism 106 to rotate. The rotation of the first belt transmission mechanism 106 will drive the lever 108 to move back and forth in a straight line to the left, and at the same time, the sliding block 107 and the lever 108 will slide relative to each other, and the slider 109 will also rotate synchronously. At this time, the vibration paddle 110 will continuously contact each heat absorbing sheet 102, causing the heat absorbing sheet 102 to vibrate, thereby shaking off the solid particles attached to the surface of the heat absorbing sheet 102, and discharging them into the head purification box 307 through the rising flue gas. A detachable sewage seat 308 is set at the bottom of the head purification box 307. When too much non-meltable solid enters the head purification box 307, the inside of the head purification box 307 can be cleaned by disassembling the sewage seat 308.
