Description

Technical Field

[0002] In industrial sectors such as chemical, metallurgical, power, and waste incineration, flue gas emissions are one of the main sources of air pollution. Flue gas contains particulate matter, acidic gases, volatile organic compounds, and high-temperature components, so it needs to be treated by flue gas emission devices during emission.

[0003] However, existing flue gas emission devices still have certain shortcomings. For example, the purification core of traditional flue gas emission devices is mostly a single filter design, and a single filter is not very effective in treating harmful gases in flue gas. Secondly, flue gas itself is usually very hot, and even after filtration, the flue gas still maintains a very high temperature. The emission of high-temperature flue gas will cause the surrounding air temperature to rise sharply, burn the feathers of birds, and thus affect the living environment of birds.

[0021] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0022] Working principle: When in use, the water pump 6 is started, and the external water source or the liquid solution to be treated for flue gas is absorbed through the water inlet pipe 7, and then sprayed out in a ring through the water delivery pipe 8, the annular pipe 9, and the mist nozzle 10, thus forming a water curtain between the two activated carbon filters 12. Then, the flue gas is transported into the treatment box 3 through the air inlet pipe 1. After being filtered by the activated carbon filter 12 on the left, it passes through the water curtain to remove some impurities and continues to pass through the activated carbon filter 12 on the right for further removal of harmful gases. At the same time, the flue gas is cooled to a certain extent after passing through the water curtain, thus preventing high-temperature gas from being directly discharged and affecting the living environment of birds. When the activated carbon filter 12 needs to be cleaned or replaced, simply press the pressure blocks on the fixing components 15 on both sides. 18. Driving the pressure rod 17 causes the wedge block 19 to slide along the inclined surface of the trapezoidal block 21, which in turn causes the insert block 23 to retract along the slide rod 20 toward the interior of the fixing box 16 and compresses the spring 22, thereby releasing the restriction effect on the baffle 14. Then, the activated carbon filter 12 can be pulled out along the interior of the slot 11 to complete the disassembly. Afterward, the cleaned activated carbon filter 12 or a new activated carbon filter 12 is reinserted into the corresponding slot 11. When the slot 24 on the baffle 14 corresponds to the insert block 23, the pressure block 18 is released. Under the action of the spring 22's rebound force, the insert block 23 will automatically insert into the corresponding slot 24, thereby realizing the installation of the activated carbon filter 12 as a whole. It is simple, convenient and practical.
