Description

Technical Field

[0001] The utility model relates to the technical field of flue gas waste heat recovery, and particularly relates to a waste heat recovery device for a new type of kiln flue gas. Background Technique

[0002] A flue gas heat exchanger is a heat energy recovery device, mainly used for recovering the heat in the flue gas generated in industrial or domestic heating systems.

[0003] The metal pipes of the flue gas heat exchanger need to be cleaned regularly because the flue gas usually contains dust, particulate matter and other deposits. Over time, these substances may accumulate on the inner wall of the metal pipes, forming a layer of dirt, which will reduce the heat conduction efficiency of the metal pipes, thus reducing the performance of the entire flue gas heat exchanger. The existing cleaning method usually involves first disassembling the flue gas heat exchanger, then removing the metal pipes, and finally cleaning the metal pipes. Such a cleaning method is rather troublesome for a series of operations, and during cleaning, power needs to be cut off and the machine needs to be stopped, affecting production efficiency. To reduce the cleaning frequency of the metal pipes in the flue gas heat exchanger and facilitate the cleaning of the dust, particulate matter and other deposits accumulated on the outer wall of the metal pipes, we propose a flue gas heat exchanger;

[0004] The existing patent (Publication No.: CN219390615U) discloses a flue gas heat exchanger, which includes a shell, a plurality of tube bundles installed inside the shell, a water inlet pipe and a water outlet pipe connected to both ends of the plurality of tube bundles, and an air inlet and an air outlet installed at the front and rear ends of the shell. There are fixing parts between the water outlet pipe and the water inlet pipe and the shell. A scraper is slidably sleeved on the outer walls of the plurality of tube bundles. The beneficial effects of the utility model are: through the mutual cooperation between the fixing parts, the scraper, the sliding rod, the connecting rod, the limiting parts and the collecting mechanism, this device can clean the dirt accumulated on the outer wall of the metal pipes inside the flue gas heat exchanger to a certain extent without disassembling the flue gas heat exchanger, reducing the cleaning frequency of the metal pipes in the flue gas heat exchanger, with simple operation and no need to cut off power and stop the machine, improving the production efficiency to a certain extent; and the scraped dirt can be collected and uniformly treated.

[0005] Regarding the above problems, the existing patent gives a solution, but when the existing flue gas heat exchanger is installed, it does not have an auxiliary installation structure. During the installation process, the user needs to detect whether the installation working surface is flat to determine the subsequent installation plan, resulting in a decrease in its installation efficiency, which the existing patent cannot solve, so it is not conducive to the user's use.

[0006] Therefore, a waste heat recovery device for a new type of kiln flue gas is proposed. Content of the Utility Model

[0028] The bearing assembly 401 includes a bearing plate 4011, a fixing plate 4012, a reinforcing rod 4013, a limiting frame 4014, and a longitudinal support plate 4015. The bearing plate 4011 is movably connected to the front side and the rear side of the top of the flue gas heat exchanger body 1. The fixing plate 4012 is fixedly connected to the bottoms of both sides of the bearing plate 4011. The reinforcing rod 4013 is threadedly connected to the inside of the fixing plate 4012. The limiting frame 4014 is fixedly connected to both sides of the top of the bearing plate 4011. The longitudinal support plate 4015 is slidably connected to the inside of the limiting frame 4014.

[0029] In this embodiment: By setting the bearing plate 4011, the fixing plate 4012, the reinforcing rod 4013, the limiting frame 4014, and the longitudinal support plate 4015, when using this waste heat recovery device for a new type of kiln furnace flue gas, the user can combine the bearing plate 4011, the fixing plate 4012, the reinforcing rod 4013, the limiting frame 4014, and the longitudinal support plate 4015 with the flue gas heat exchanger body 1, so that the bearing plate 4011, the fixing plate 4012, the reinforcing rod 4013, the limiting frame 4014, and the longitudinal support plate 4015 can cooperate with each other to fix the auxiliary installation assembly 402 around the flue gas heat exchanger body 1, thus facilitating the subsequent use by the user.
