The combustion module is used for combusting the group of the combustible garbage crushing materials. High-temperature flue gas generated by the combustion is used as a heat source of a waste heat boiler, so as to drive a steam turbine to work. Furthermore, the application also provides a garbage combustion method capable of ensuring temperature stability.

Description

Technical Field

[0001] This invention relates to the field of municipal solid waste incineration power generation technology, and in particular to a waste combustion system and method that ensures stable temperature. Background Technology

[0002] Urban solid waste mainly includes municipal solid waste, sewage sludge, kitchen waste, and medical waste. Currently, landfill and incineration are the primary technologies used for its treatment. Cities with large volumes of municipal solid waste and high calorific value are encouraged to use incineration power generation technology for waste treatment. This can reduce the land area occupied by waste treatment, reduce secondary pollution, and achieve the harmlessness, reduction, and resource recovery of waste.

[0003] Due to the diversity, complexity, and unevenness of the composition of municipal solid waste, the calorific value of the waste fluctuates significantly. Examples include shredded waste wood, discarded clothing, shoes, waste paper, and plastic products. Although shredded waste materials continuously enter the incineration unit, the composition of the shredded waste materials entering at different times differs. For example, when the shredded waste materials entering the waste incineration system are mostly waste paper, the combustion time is short and less heat is generated. Conversely, when the shredded waste materials entering the waste incineration system are mostly wood, the combustion time is long and more heat is generated. Ultimately, this leads to unstable combustion temperatures in the waste incineration system, requiring operators to conduct real-time on-site inspections and adjustments. This causes significant challenges and increases the workload for operators. Summary of the Invention

[0004] In view of this, the present invention discloses a waste incineration system that ensures stable temperature.

[0005] It is also necessary to provide a waste incineration method that ensures stable temperatures.

[0006] A waste incineration system ensuring stable temperature includes a waste storage module, a non-combustible material removal module, a crushing module, a drying module, a temperature stabilization module, a feeding module, and an incineration module. The waste storage module stores municipal solid waste transported by garbage trucks. The non-combustible material removal module physically removes iron, glass, and bricks from the stored municipal solid waste to obtain combustible waste. The crushing module crushes the combustible waste to obtain combustible waste shredded material. The drying module dries the combustible waste shredded material. The feeding module groups and feeds the dried combustible waste shredded material to the incineration module for combustion. The temperature stabilization module measures the current volume and weight of each group of combustible waste shredded material fed by the feeding module. When the current weight value corresponds to a pre-stored baseline weight value, the module controls the feeding rate based on the current volume and a predetermined feeding time to deliver the group of combustible waste shredded material to the incineration module. The incineration module incinerates the group of combustible waste shredded material, and the high-temperature flue gas generated during incineration serves as a heat source for a waste heat boiler to drive a steam turbine.

[0007] A method for ensuring stable temperature in waste combustion, applied in a waste combustion system that includes a waste storage module, a non-combustible material removal module, a crushing module, a drying module, a temperature stabilization module, a feeding module, and an incineration module, comprising the following steps:

[0008] Utilizing waste storage modules to store urban household waste transported by garbage trucks;

[0009] The non-combustible material removal module is used to physically remove iron, glass, and bricks from stored municipal solid waste to obtain combustible waste.

[0010] The crushing module is used to crush combustible waste to obtain combustible waste crushed material.

[0011] The combustible waste shredded material is dried using a drying module;

[0012] The feeding module transports the dried, shredded combustible waste in groups to the incineration module for combustion. Specifically, the temperature stabilization module measures the current volume and weight of each group of shredded combustible waste transported by the feeding module. When the current weight of the shredded combustible waste corresponds to a pre-stored baseline weight, the feeding module's conveying rate is controlled based on the current volume and the scheduled conveying time to deliver the group of shredded combustible waste to the incineration module. The incineration module then incinerates the group of shredded combustible waste, and the high-temperature flue gas generated serves as a heat source for the waste heat boiler, producing steam and driving a turbine to power a generator.

[0013] In the aforementioned waste incineration system and method for ensuring stable temperature, a waste storage module stores municipal solid waste transported by waste trucks. A non-combustible material removal module physically removes iron, glass, and bricks from the stored municipal solid waste to obtain combustible waste. A crushing module crushes the combustible waste to obtain combustible waste shredded material. A drying module dries the combustible waste shredded material. A temperature stabilization module measures the current volume and weight of each batch of combustible waste shredded material conveyed by the feeding module. When the current weight value of the combustible waste shredded material corresponds to a pre-stored benchmark weight value, the feeding rate of the feeding module is controlled according to the current volume and the predetermined conveying time to deliver the batch of combustible waste shredded material to the incineration module. Thus, the weight of the combustible waste shredded material is monitored before entering the incineration module to ensure that the weight of the combustible waste shredded material entering the incineration module is consistent, thereby ensuring stable incineration.
