Description
Technical Field
[0001] This utility model relates to the technical field of flue gas purification equipment, specifically a flue gas purification device for waste incineration power generation. Background Technology
[0002] Waste-to-energy flue gas purification equipment is a device specifically designed to treat the harmful flue gas generated during the waste incineration process. It uses various technical means, such as deacidification, dust removal, denitrification, and removal of harmful substances such as dioxins, to purify the flue gas generated by waste incineration to meet emission standards, thereby reducing environmental pollution and ensuring the environmental protection and sustainability of the waste-to-energy incineration process.
[0003] During the normal operation of a waste incinerator, the flue gas temperature is usually high, generally around 800-1000℃. This is because the heat generated by the combustion of waste at high temperatures raises the flue gas temperature. This high temperature is conducive to the decomposition of some pollutants, such as the oxidation and decomposition of some organic matter at high temperatures.
[0004] In the process of purifying flue gas from waste incineration, although the filter can achieve a certain degree of filtration and purification of particulate matter in the flue gas, the impact of high-temperature flue gas and the phenomenon of thermal expansion and contraction will have a significant impact on the filter during long-term operation. Specifically, the wire mesh structure of the filter may gradually loosen and the pore size will increase. This structural change will weaken the filter's ability to intercept particulate matter, thereby leading to a decrease in the flue gas purification effect and failing to effectively guarantee the quality of flue gas purification. Therefore, a flue gas purification device for waste incineration power generation is proposed to address the above problems. Utility Model Content

[0030] Please see Figure 1-8 This utility model provides a technical solution:
[0031] A flue gas purification device for waste incineration power generation includes a water pipe 1 and a housing assembly 2. A filter assembly 3 is fixedly connected to the inside of the housing assembly 2. A vibration generating assembly 4 is installed inside the filter assembly 3. The filter assembly 3 includes a metal shell 31. A water inlet pipe 32 and a water outlet pipe 33 are fixedly connected to the front end of the metal shell 31. A spring plate 34, a metal partition plate 35, a metal pipe 36, and an embedded pipe 37 are fixedly connected to the inside of the metal shell 31. The vibration generating assembly 4 includes a shaft 41. The shaft 41 is rotatably connected to the inside of a vertical plate 42. A turbine blade 43 is fixedly connected to the outside of the shaft 41. A sleeve 44 is fixedly connected to the outside of the shaft 41. A spring 45 is fixedly connected to the outside of the sleeve 44. A hammer 46 is fixedly connected to the end of the spring 45 away from the sleeve 44. The vertical plate 42 is fixedly connected to the inside of the embedded pipe 37.
[0032] As a further implementation of this solution, the front end of the water inlet pipe 32 is fixedly connected to the rear end of the water pipe 1. Both the inner sides of the water inlet pipe 32 and the water pipe 1 are hollow structures. The inner side of the water inlet pipe 32 is connected to the inner side of the water pipe 1. The water pipe 1 is fixed to the outlet of the water pump. Through the above settings, this structural design ensures that the cooling water can smoothly enter the interior of the water inlet pipe 32 from the water pump through the water pipe 1, providing stable water flow support for the subsequent heat exchange and cooling process.
[0033] As a further implementation of this solution, the housing assembly 2 includes a housing 21. The housing 21 has an exhaust groove 22, a connecting port 23, an air inlet groove 24, and a collection port 27 on its inner side. The air inlet groove 24, the connecting port 23, and the exhaust groove 22 are connected. A collection box 28 is fixedly connected to the inside of the collection port 27 by bolts. The collection box 28 is sealed to the front end of the housing 21 by a rubber gasket. An air inlet pipe 25 is fixedly connected to the rear end of the housing 21. A fixing frame 26 is fixedly connected to the inner side of the housing 21. The inner side of the fixing frame 26 is fixedly connected to the outer side of the metal shell 31. Through the above settings, a channel is provided for the flow of flue gas, while ensuring the structural stability of the inside of the collection port 27 and preventing flue gas leakage, thereby improving the sealing and reliability of the equipment. The collection box 28 is located at the lower end of the filter assembly 3, which facilitates the entry of particles falling from the filter assembly 3 into the collection box 28 for collection.
[0034] As a further implementation of this solution, the metal shell 31 has through holes at both the upper and lower ends, and the inner side of the metal tube 36 is hollow. The inner side of the metal tube 36 is aligned with the through holes of the metal shell 31. Through the above arrangement, it is ensured that the flue gas can pass smoothly through the metal shell 31 and the metal tube 36 to achieve efficient filtration and heat exchange. This structure not only improves the flue gas purification efficiency, but also reduces the flue gas temperature through heat exchange, reduces the damage of high temperature to the equipment, and extends the service life of the equipment.
[0035] As a further implementation of this solution, spring plates 34 are fixed at both the upper and lower ends of the metal shell 31. The spring plates 34 are inserted and fixed inside the metal partition 35, with a gap between the two spring plates 34. The spring plates 34 are aligned vertically with the hammer 46. The inner side of the embedded tube 37 is a hollow structure, and the turbine blades 43 are embedded and installed inside the embedded tube 37. There are multiple vertical plates 42, with the rear vertical plate 42 fixed inside the metal shell 31. Through the above arrangement, the alignment design of the spring plates 34 and the hammer 46, combined with the rotation and centrifugal force of the hammer 46, can generate vibration and transmit it to the metal partition 35 and the metal shell 31. This vibration can effectively remove particulate matter inside the metal shell 31 and the metal tube 36, prevent filter clogging, improve flue gas purification efficiency, and ensure long-term stable operation of the equipment.
[0036] Workflow: When purifying the flue gas generated from waste incineration, the flue gas is discharged into the inlet pipe 25, then enters the inlet slot 24, and then enters the through-hole in the metal shell 31 through the connecting port 23 and the exhaust slot 22. It then passes through the metal pipe 36 and exits from the through-hole at the top of the metal shell 31. The metal pipe 36 and the through-hole in the metal shell 31 filter the particles in the flue gas before it is discharged from the top of the exhaust slot 22, thus achieving the purification of the flue gas. Due to the high temperature of the flue gas... When the flue gas passes through filter assembly 3, it will undergo thermal expansion and contraction. If the temperature of filter assembly 3 cannot be controlled, the through holes in filter assembly 3 will become larger, which will affect the purification quality of the flue gas. When the flue gas passes through metal pipe 36, metal pipe 36 absorbs the heat in the flue gas. Water is drawn by a water pump and transported through water pipe 1 to the inside of water inlet pipe 32. From water inlet pipe 32, it enters the inside of embedded pipe 37. When the water passes through turbine blades 43, the kinetic energy of the water fluid will drive turbine blades 43 to rotate. The rotation of turbine blades 43 drives the shaft 41 to rotate, which in turn drives the sleeve 44, spring 45, and hammer 46 to rotate. When the hammer 46 rotates, it collides with the spring plate 34 under centrifugal force, causing the spring plate 34 to vibrate. The spring plate 34 extends into the metal partition 35, transmitting the vibration to the metal partition 35 and the metal shell 31, causing the metal shell 31 to rotate. This vibration removes particles from the through-holes of the metal shell 31 and inside the metal pipe 36, improving flue gas purification efficiency. The water flows into the metal shell 31, where it exchanges heat with the metal pipe 36. The arrangement of the metal baffles 35 provides an approximately S-shaped channel for the water flow, ensuring that each metal baffle 35 is cooled. At the same time, the metal shell 31 is also cooled. The water after heat exchange flows out from the outlet pipe 33 for collection. Based on the above principles, when purifying the flue gas generated by waste incineration, the device can cool the filter components 3 used for purification in real time. This will significantly reduce the probability of deformation of the metal shell 31, thereby improving the quality of delayed purification.
