Description

Technical Field

[0002] During cement production, the high-temperature flue gas produced by cement kilns has the characteristics of high temperature, high dust content, and high NOx content. These characteristics make it a great threat to the environment and equipment. Therefore, effective treatment is particularly important. By adopting advanced treatment technologies, such as high-temperature electrostatic precipitator, metal fiber felt filtration and dust removal, and selective catalytic reduction denitrification technology, the flue gas purification effect can be significantly improved; Existing flue gas desulfurization and dust removal devices for cement kilns usually occupy a large area and are very inconvenient to use. The installation location and layout structure of the device need to be carefully considered to ensure that the purification process is more energy-efficient and efficient. More importantly, the existing flue gas desulfurization and dust removal devices use the method of spraying the desulfurization catalyst directly into the pretreatment chamber during desulfurization treatment. Although this method is simple and easy to implement, the short contact time between the desulfurization catalyst and the flue gas leads to insufficient treatment of the flue gas. In addition, when the gas detection after subsequent treatment does not meet the standards, the existing device cannot return the gas to the device for re-processing, which means that once the gas emissions do not meet the standards, they will be directly discharged into the environment, causing serious pollution to the atmospheric environment.

[0003] Therefore, a cement kiln flue gas desulfurization and dust removal energy-saving integrated device is needed to improve the above problems. Summary of the invention

[0004] In order to solve the problem that the desulfurization and dust removal energy-saving integrated device performs desulfurization and dust removal on cement kiln flue gas, the existing flue gas desulfurization and dust removal device adopts the method of spraying the desulfurization catalyst directly into the pretreatment chamber during desulfurization treatment.

[0010] As a preferred embodiment of the present invention, the flexible baffles are all located on one side of the limiting block. The partition housing divides the installation housing into an outer treatment cavity and an inner treatment cavity. The outer housing is located in the inner cavity of the outer treatment cavity, and the inner housing is located in the inner cavity of the inner treatment cavity.

After layers of reactions, the cement kiln flue gas is catalyzed more thoroughly, thereby solving the problem of spraying the desulfurization catalyst directly into the pretreatment chamber, but the desulfurization catalyst is not sufficiently treated due to the short contact time between the flue gas and the flue gas.

[0017] The present invention arranges a gas analyzer in the cement kiln flue gas desulfurization and dust removal energy-saving integrated device to generate an electrical signal which is transmitted to a controller through a wire. When a set value is reached, the controller controls the electric control valve to operate and close, and one side of the piston is subjected to the air pressure of the third conduit, and the other side of the piston is subjected to the air pressure of the second conduit. When the air pressure in the second conduit is greater than the air pressure in the third conduit, the piston slides downward in the inner cavity of the limiting hole, and the gas in the second conduit flows into the third conduit through the connecting hole. When the gas does not meet the emission standard, it will be repeatedly purified, thereby solving the problem that when the gas detection after subsequent treatment does not meet the standard, the existing device cannot return the gas to the device for re-processing, which means that once the gas emission does not meet the standard, it will be directly discharged into the environment, causing serious pollution to the atmospheric environment.

At the same time, since the inner walls of the first spiral plate 810 and the second spiral plate 815 are respectively provided with flexible baffles 816, the flexible baffles 816 separate the inner cavities of the first spiral plate 810 and the second spiral plate 815 into multiple separate spaces, when the first spiral plate 810 and the second spiral plate 815 rotate, when the flexible baffle 816 is located on one side of the limit block 5 , its flexible baffle 816 and the first spiral plate 810 form a closed space, and at the same time, the controller 11 controls the electric-controlled atomizing nozzle 6 to operate, and its electric-controlled atomizing nozzle 6 sprays out a desulfurization catalyst liquid, and its desulfurization catalyst liquid and cement kiln flue gas are desulfurized. When the flexible baffle 816 contacts the limit block 5, the limit block 5 on the arc surface lifts the flexible baffle 816, thereby opening the flexible baffle 816, and the cement kiln flue gas moves to one side. Its two sets of reverse spiral structures increase the reaction time of the gas inside the device, and the cement kiln flue gas is catalyzed more thoroughly after layers of reaction, thereby solving the problem of spraying the desulfurization catalyst directly into the pretreatment chamber, but the desulfurization catalyst is not sufficiently treated due to the short contact time between the flue gas and the flue gas; The purified gas flows into the detection component 13 through the gas outlet pipe 12, an electric control valve 1302 is installed at one end of the first conduit 1301, and a second conduit 1303 is installed on the outer wall of the first conduit 1301, wherein the port of the second conduit 1303 is connected to a detection shell 1304, and a gas analyzer 1305 is embedded and installed on the outer wall of the detection shell 1304, and the sensing end of the gas analyzer 1305 is located in the inner cavity of the detection shell 1304. When the gas passes through the gas analyzer 1305, the gas analyzer 1305 generates data according to the gas, and then the gas analyzer 1305 generates an electrical signal which is transmitted through the wire. To the controller 11, when the set value is reached, the controller 11 controls the electric control valve 1302 to operate, the electric control valve 1302 operates to close, and a limit hole 1307 is opened on the outer wall of the partition block 1306, wherein the cross section of the limit hole 1307 is a T-shaped structure, and a piston 1308 is slidably connected to the inner wall of the limit hole 1307, and a limit spring 1309 is installed just above the piston 1308 and on the inner wall of the limit hole 1307, and one end of the limit spring 1309 is connected to the outer wall of the piston 1308. Under the action of the gas pressure in the inner cavity of the pipeline increases, the gas exerts pressure on the piston 1308, and the outer wall of the partition block 1306 A vent hole 1310 is provided in a circular array on the upper part, and the connection between the vent hole 1310 and the limiting hole 1307 is a communicating structure, and the vent hole 1310 is located at the lower side of the piston 1308, and a third conduit 1311 is provided on the bottom outer wall of the detection housing 1304, wherein the third conduit 1311 is connected to the outer wall of the intake pipe 9, and the third conduit 1311 is located on one side of the booster fan 10. Because one side of the piston 1308 is subjected to the air pressure of the third conduit 1311, the other side of the piston 1308 is subjected to the air pressure of the second conduit 1303. When the air pressure in the second conduit 1303 is greater than the air pressure in the third conduit 1311, the air in the second conduit 1303 is increased. The piston 1308 slides downward in the inner cavity of the limit hole 1307. When the piston 1308 moves to the bottom of the vent hole 1310, the gas in the second conduit 1303 flows into the third conduit 1311 through the vent hole 1310. When the air pressure on both sides of the piston 1308 is the same, the stretched limit spring 1309 drives the piston 1308 to reset. When the gas does not meet the emission standards, it will be repeatedly purified, thereby solving the problem that when the gas detection after subsequent treatment does not meet the standards, the existing device cannot return the gas to the device for re-processing, which means that once the gas emission does not meet the standards, it will be directly discharged into the environment, causing serious pollution to the atmospheric environment.
