Description

Technical Field

[0001] The utility model belongs to the technical field of waste treatment, and particularly relates to a horizontal grate incinerator. Background Art

[0002] With the acceleration of the urbanization process, the generation amount of municipal domestic waste is also increasing continuously. One of the main ways to deal with these wastes is incineration treatment. Waste incineration can not only effectively reduce the volume of waste, but also convert it into energy resources. However, the existing waste incineration equipment generally has problems such as low combustion efficiency, high pollutant emissions, and complex operation, which are difficult to meet the requirements of modern environmental protection and energy utilization.

[0003] The existing waste incinerators are mainly grate furnaces and fluidized bed incinerators, and the daily treatment capacity of a single device is more than 400 tons. When the treatment capacity is small, the incineration effect of these devices is not good, and the investment and operation costs are high. In order to meet the demand for small-scale waste treatment, the small-scale incinerators on the current market mainly adopt single-body vertical incinerators, and the inner diameter of the furnace body generally does not exceed 3 meters, and the daily treatment capacity is only twenty or thirty tons. If the treatment capacity is to be increased, the furnace bed area must be enlarged. However, if the inner diameter of the vertical incinerator is enlarged, many problems will be faced in feeding and slag removal, such as uneven feeding and unsatisfactory slag removal effect, resulting in low treatment efficiency. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a horizontal grate incinerator, which can achieve the following: by adopting a separated and independent combustion chamber design, it solves the problem of uneven combustion caused by different waste components and calorific values, and further optimizes the combustion efficiency and environmental protection performance.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A horizontal grate incinerator includes a furnace body for incinerating waste, and a feeding mechanism is arranged at the top of the furnace body;

[0007] The feeding mechanism is used to put the waste to be incinerated into the furnace body;

[0008] One end of the feeding mechanism is provided with a feeding device, and the feeding device is used to convey the waste to be incinerated to a feeding trolley on the feeding mechanism;

[0009] A slag conveying mechanism is arranged at the bottom of the furnace body, and the slag conveying mechanism is used to convey the waste after incineration out;

[0010] A plurality of combustion chambers and a blanking chamber are arranged inside the furnace body, and the combustion chambers and the blanking chamber are arranged alternately; a slag discharge pipe is correspondingly arranged at the bottom of each combustion chamber.

[0011] Further, an air inlet pipe is provided at the bottom of the furnace body, and a smoke exhaust pipe is provided at the top of the furnace body.

[0012] Further, air outlet holes are formed on the side surface of the air inlet pipe, and smoke exhaust holes are formed on the side surface of the smoke exhaust pipe.

[0013] Further, a blower is provided at one end of the air inlet pipe.

[0014] Further, branch pipes are provided on both sides of the slag discharge pipe, and the top ends of the branch pipes are connected to the bottom of the furnace body.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] Firstly, a plurality of independent combustion chambers are arranged in the furnace body, and the garbage is separated by the wall. This not only provides sufficient combustion space for the garbage, but also dries the garbage by the high temperature of the wall, improves the calorific value of the garbage, and promotes the improvement of the combustion efficiency. This design solves the problem of incomplete combustion of garbage in the traditional incinerator, making the combustion more thorough and efficient.

[0017] Secondly, the feeding mechanism arranged at the top of the furnace body can evenly distribute the garbage to be incinerated in each combustion chamber, avoiding the uneven combustion phenomenon caused by garbage accumulation. The movement of the feeding trolley and the continuous conveying of the feeding mechanism ensure the uniform feeding of the garbage, improving the incineration effect. In addition, the combined use of the feeding mechanism and the feeding trolley simplifies the operation process, reduces manual intervention, and improves the automation level of the equipment.

[0018] Thirdly, the slag conveying mechanism arranged at the bottom of the furnace body can timely discharge the slag after combustion, preventing the slag accumulation from affecting the combustion efficiency. The design of the slag discharge pipe and the branch pipes ensures the smooth discharge of the slag, further improving the continuity and stability of the incineration process. This design solves the problem of inconvenient slag treatment in the traditional incinerator and ensures the efficient operation of the incinerator.

[0019] In addition, the arrangement of the air inlet pipe and the blower ensures sufficient oxygen supply in the combustion chamber. The air outlet holes on the air inlet pipe can evenly distribute the air, improving the combustion efficiency. The design of the smoke exhaust pipe and the smoke exhaust holes effectively discharges the flue gas generated by combustion, avoiding the interference of the flue gas on the combustion process. The use of the regulating valve enables the smoke exhaust and air intake to be adjusted according to the actual combustion situation, optimizing the combustion conditions and reducing pollutant emissions. This solution solves the problems of uneven air supply and inaccurate combustion control in the traditional incinerator, significantly improving the incineration efficiency and environmental protection performance.

[0020] Finally, compared with traditional vertical incinerators, the overall horizontal design makes it easier to adjust the length according to the processing capacity, thereby increasing the processing capacity without increasing the width of the furnace body. This not only avoids the problems of feeding and slag removal caused by increasing the inner diameter of vertical incinerators but also makes full use of space, improving the flexibility and adaptability of the equipment.

[0033] See Figure 3 , air outlet holes 131 are opened on the side of the air inlet pipe 13, and the air outlet holes 131 introduce the air conveyed by the fan 14 into the combustion chamber 11; smoke exhaust holes 151 are opened on the side of the smoke exhaust pipe 15, and the smoke exhaust holes 151 are used to discharge the flue gas generated by combustion.
