Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hazardous waste flue gas coking, and in particular to a disturbance anti-coking device in a high temperature environment of the hazardous waste industry. Background Art
[0002] Coking is a problem that troubles industry insiders, especially in the process of hazardous waste incineration with high salt content and liquid furnaces in alkaline environments. In the process of burning high calorific value salt-containing liquid hazardous waste, ash particles flow with the flue gas. When passing through the connecting pipes, the ash particles will be cooled due to the low temperature of the pipe wall. If the liquid slag particles have solidified due to the temperature drop before approaching the water-cooled wall or furnace wall, when they adhere to the heated surface pipe wall, a loose ash layer will be formed, which can be easily removed by blowing soot during operation. When the temperature in the liquid furnace is high, some ash particles have reached a molten or semi-molten state. If these ash particles are not sufficiently cooled to reach a solidified state before contacting the pipe wall, they will have a high bonding ability and are easy to adhere to the flue wall, or even reach a molten state. The adhesion of molten or semi-molten ash particles and unburned coke causes coking to continue to develop.
[0003] In actual use, the fusible or gasifiable substances contained in the coal powder particles evaporate rapidly during the combustion process, enter the flue gas in a gaseous state, and condense when the temperature drops, or adhere to the flue wall, or condense on the surface of the fly ash particles to form a molten alkali film, which then adheres to the heated surface to form an initial coking layer, which becomes a condition for the development of coking and eventually forms large coke blocks, causing certain damage to the flue.

[0009] Furthermore, a thickened plate is provided on the surface of one end of the iron block away from the soft rope, and the surface of the thickened plate is fixedly connected to the inner wall surface of the main flue.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] For example, see Figure 1-Figure 4 As shown in the figure, a disturbance anti-coking device under high temperature environment in hazardous waste industry includes a main flue 100, one end of the main flue 100 is penetrated and fixedly connected with a liquid furnace 500, the other end of the main flue 100 is penetrated and fixedly connected with a waste heat boiler 600, a feeder 700 is arranged at the bottom of the waste heat boiler 600, a feeder cone 900 is arranged between the waste heat boiler 600 and the feeder cone 700, the top of the feeder cone 900 is fixedly connected to the bottom surface of the waste heat boiler 600, and the bottom is fixedly connected to the top of the feeder cone 700. The design of the feeder cone 900 helps to achieve uniform distribution in the process of solid particles flowing to the feeder cone 700. Through the appropriate angle and shape design, it can be ensured that the solid particles are evenly distributed in the feeder cone 700 during the feeding process, avoiding the situation that may cause uneven flow or blockage. The top of the feeder cone 900 is fixedly connected to the bottom surface of the waste heat boiler 600, and the bottom is fixedly connected At the top of the feeder 700, the stability of the entire system is enhanced, and it ensures a tight connection between the feeder cone and the waste heat boiler 600 and the feeder 700, reducing possible loosening or displacement, thereby improving the reliability and safety of the system. A disturbance air duct branch 200 is arranged at the bottom of the main flue 100, and the bottom of the disturbance air duct branch 200 is penetrated and fixedly connected with a gas distributor 300. There are multiple groups of disturbance air duct branches 200, and they are evenly connected to the top of the gas distributor 300 and the bottom surface of the main flue 100 respectively. By introducing gas from the gas distributor 300 and distributing it evenly into the main flue 100, the gas can be better mixed in this area, thereby improving the combustion efficiency or other corresponding fluid process effects. By introducing gas on the bottom surface of the main flue, it can help to improve the uniformity of temperature. The bottom of the gas distributor 300 is penetrated and fixedly connected with an air supply channel 400.
[0030] When in use, the material is worked in the liquid furnace 500, and the flue gas generated by the processing enters the waste heat boiler 600 through the main flue 100. At the same time, when the flue gas enters the main flue 100, the high-pressure fan or compressed gas inside the air supply channel 400 is used to provide continuous and stable high-pressure wind, and then enters the gas distributor 300 through the air supply channel 400. The gas distributor 300 distributes the wind into several branches according to the fluid law and sends the wind into the main flue 100 through the disturbance wind branch 200. After the wind enters the main flue 100, it can provide a cold source. Its purpose is to cool the molten particles that sink due to gravity to form loose solids, and to provide a forward thrust for the solid particles that form solids to prevent the particles from settling, gathering and clogging the flue. After the solid particles enter the waste heat boiler 600 through the flue 1 under the support of their own gravity and wind force, they enter the discharge cone 900 and are finally discharged through the discharger 700, effectively avoiding blockage inside the main flue 100.
[0031] At the same time, in order to prevent impurities from sticking to the inner wall of the flue, please refer to Figure 1-Figure 4 As shown in the figure, an anti-sticking device 800 is arranged inside the main flue 100, and the anti-sticking device 800 includes a triangular support frame 803, the surface of the triangular support frame 803 is fixedly connected to the top inner wall of the disturbance air duct branch 200, the top of the triangular support frame 803 is rotatably connected to a wind wheel 804, the top of the wind wheel 804 is fixedly connected to a triangular rod 805, the end of the triangular rod 805 away from the wind wheel 804 is fixedly connected to a round rod 806, the surface of the end of the round rod 806 away from the triangular rod 805 is provided with a soft rope 807, and the end of the soft rope 807 away from the round rod 806 is fixedly connected to an iron block 808. 08. A thickened plate 801 is provided on the surface of one end of the iron block 808 away from the soft rope 807. The surface of the thickened plate 801 is fixedly connected to the inner wall surface of the main flue 100. When the iron block 808 collides with the thickened plate 801, it helps to vibrate the impurities stuck inside the main flue 100 to make them fall off. There are three groups of soft ropes 807 and iron blocks 808, which are evenly fixedly connected to the surface of the triangular rod 805. This can achieve multiple effects such as balanced load distribution, stable structure, optimized space utilization, simplified installation and maintenance, and improved overall performance, which helps to improve the efficiency and reliability of the system.
[0032] When in use, after the disturbance duct branch 200 supplies air to the inside of the main flue 100, it drives the wind wheel 804 in its inner wall to rotate synchronously. It is explained here that the wind wheel 804 is connected to the inner wall of the disturbance duct branch 200 by using the triangular support frame 803 at the bottom. At the same time, after the wind wheel 804 rotates, it drives the triangular rod 805 connected to the top to move synchronously. Round rods 806 and soft ropes 807 are connected to the end points of the triangular rod 805. The iron block 808 connected to the other end is driven to rotate around the wind wheel 804 by swinging. At the same time, after the iron block 808 rotates, it collides and hits the thickened plate 801 on the inner wall of the main flue 100. It is explained here that the iron block 808 generates vibration by hitting the thickened plate 801, which helps to assist in the removal of impurities stuck to the main flue 100.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
