In particular, the waste incineration system 1 of the present application further comprises a cooling assembly 40. At least two wind chambers 10 are arranged side by side and at intervals, an intermediate channel 11 is formed between the opposite outer side walls of two adjacent wind chambers 10, an incineration grate 20 is arranged at the top of the wind chambers 10, the bottom of the incineration grate 20 is communicated with the inside of the wind chambers 10, a hydraulic cylinder 30 is arranged outside the incineration grate 20 and is arranged in the intermediate channel 11, the hydraulic cylinder 30 is used for driving grate segments in the incineration grate 20 to move, a cooling assembly 40 comprises a first fan 41, a cooling pipe 42 and a tuyere 43, the cooling pipe 42 is arranged in the intermediate channel 11, the cooling pipe is connected to an air outlet of the first fan 41, the tuyere 43 is arranged in the cooling pipe 42, and the tuyere 43 is arranged towards the hydraulic cylinder 30 and used for exhausting air to the hydraulic cylinder 30 so as to cool the hydraulic cylinder 30.

Therefore, the air nozzle 43 can be used for blowing air to the hydraulic cylinder 30 in real time, so that the temperature of the hydraulic cylinder 30 can be timely reduced in the running process of the hydraulic cylinder 30, and on one hand, the sealing performance and the service life of the hydraulic cylinder 30 are improved. On the other hand, the temperature of the hydraulic oil in the hydraulic cylinder 30 can be effectively reduced, so that the hydraulic oil maintains a good viscosity index, the load of a cooling device of the oil station is reduced, and the running stability of a hydraulic oil system is improved.

In some embodiments, the cooling pipe 42 includes a main cooling pipe 420 and a plurality of segments of sub-cooling pipes 421, the plurality of segments of sub-cooling pipes 421 are disposed on the main cooling pipe 420 and are communicated with the main cooling pipe 420, each sub-cooling pipe 421 extends along a direction forming an angle with the extending direction of the main cooling pipe 420, and each sub-cooling pipe 421 is provided with a tuyere 43. Therefore, the cooling air is conveyed in a grading manner, the arrangement of pipelines is simplified, and the flowing direction of the cooling air is reasonably distributed, so that the sub-cooling pipe 421 performs targeted air blowing cooling on the hydraulic cylinder 30, and the cooling efficiency is improved.

In some embodiments, one end of the sub cooling pipe 421 is welded to the main cooling pipe 420, and the other end of the sub cooling pipe 421 is located above the hydraulic cylinder 30 to blow air toward the hydraulic cylinder 30. Specifically, one end of the sub-cooling pipe 421 is connected to the main cooling pipe 420, and the other end is disposed in a suspended manner, and one end of the suspended arrangement is aligned with the hydraulic cylinder 30. Thus, after the main cooling pipe 420 is installed and fixed, the sub-cooling pipe 421 is installed accordingly, and a support structure for installing the sub-cooling pipe 421 is not required. The sub-cooling pipe 421 and the main cooling pipe 420 are connected by welding, so that the connection tightness of the sub-cooling pipe and the main cooling pipe can be improved, and the connection process is simplified.

In some embodiments, the air nozzle 43 and the sub-cooling pipe 421 may be integrally formed, which further simplifies the structure and improves the efficiency of design and installation.

For example, since the main cooling pipes 420 are disposed at the middle portion of the middle passage 11 in the width direction, distances from the main cooling pipes 420 to the hydraulic cylinders 30 on both sides, respectively, are equal, the sub cooling pipes 421 located on both sides of the main cooling pipes 420 may be disposed at the same length, and the air volume and the force of the cooling air obtained by the hydraulic cylinders 30 on both sides are substantially the same.

Each sub-cooling pipe 421 corresponds to one hydraulic cylinder 30, the air quantity distributed to each sub-cooling pipe 421 does not need to be too large, and the pipe diameter of the sub-cooling pipe 421 is set to be smaller than that of the main cooling pipe 420, so that reasonable distribution of the air quantity of the cooling air is facilitated, the cooling effect is achieved, and meanwhile, energy is saved.

In some embodiments, the outer side walls of two adjacent wind boxes 10 are provided with mounting brackets 12, and the main cooling pipes 420 are connected to the mounting brackets 12 through the straps 13. Illustratively, the strap 13 may be a steel hoop in the shape of a circular arc, which is bolted into the mounting bracket 12. The strap 13 has a simple structure and a simple installation process, so that the main cooling pipe 420 can be effectively installed and fixed in the middle channel 11 of the two air chambers 10, which is beneficial to the transmission of cooling air for the hydraulic cylinder 30.

Since the cooling pipe 42 and the tuyere 43 are disposed in the intermediate passage 11, and the intermediate passage 11 is in an environment of high temperature and humidity, in some embodiments, the surfaces of both the cooling pipe 42 and the tuyere 43 are provided with rust-proof coatings. By applying the rust-preventive coating, it is possible to improve the rust-preventive properties of the cooling pipe 42 and the tuyere 43 and to improve the reliability of the use of the cooling block 40.

In some embodiments, the hydraulic cylinder 30 includes a plurality of hydraulic cylinders 30, and therefore, the air nozzle 43 is also provided in a plurality, and the plurality of air nozzles 43 correspond to the plurality of hydraulic cylinders 30 one to one. Since the fire grate segments of the fire grate 20 need to carry the garbage to move along the burning path, a plurality of fire grate segments need to be arranged along the garbage moving direction, and correspondingly, a plurality of hydraulic cylinders need to be arranged to drive the fire grate segments to move. Therefore, the plurality of air nozzles 43 are provided in one-to-one correspondence with the hydraulic cylinders 30, and each hydraulic cylinder 30 can be effectively cooled, thereby improving the usability and reliability of the entire refuse incineration system 1.

In some embodiments, the waste incineration system 1 further comprises a pusher platform 50, a pusher 51 is disposed on the pusher platform 50, the pusher 51 is disposed at the waste inlet of the incineration grate 20, the pusher 51 is used for pushing the waste into the incineration grate 20, and the first fan 41 is disposed on the pusher platform 50. The pusher platform 50 can generate odor due to the accumulation of garbage, and the odor of the garbage around the pusher platform 50 can be absorbed by arranging the first fan 41 on the pusher platform 50, so that the flowing efficiency of air is improved, and the air quality of the environment around the pusher platform 50 is improved.

In some embodiments, the waste incineration system 1 further comprises a second fan 60 disposed on the pusher platform 50, the second fan 60 is in communication with the intermediate channel 11, and the second fan 60 is spaced apart from the first fan 41. The garbage generates a great deal of heat during the incineration process at the incineration grate 20, and a furnace wall (not shown) is arranged above the incineration grate 20 to surround the synthetic furnace chamber so as to keep the high temperature of the combustion process. However, excessive temperatures can reduce the life of the furnace wall bricks, and therefore require corresponding furnace wall cooling structures (not shown). The second fan 60 is used for providing cooling air for the furnace wall cooling structure, and the air suction port of the second fan 60 is arranged at the position of the middle channel 11 adjacent to the pusher platform 50. Thus, the odor collected around the pusher platform 50 is sucked by the first fan 41 and blown into the intermediate passage 11 through the cooling pipe 42, and the cooling air containing the odor is blown toward the hydraulic cylinder 30 through the tuyere 43 and then exists in the intermediate passage 11, and the cooling air is sucked again by the second fan 60 and is transported through the furnace wall cooling structure to cool the furnace wall. Thus, not only can the odor of the garbage around the pusher platform 50 be effectively removed, but also the cooling air cooled by the hydraulic cylinder 30 can be used again for cooling the furnace wall, which is beneficial to saving energy.
