Embodiment Construction

[0028] Below in conjunction with example and accompanying drawing, this method and device are further described

[0029] figure 1 It is a method and device for stable incineration of stale garbage with oxygen-enriched high-temperature intelligent control. The whole system includes a grate incinerator, an oxygen-enriched combustion system and a comprehensive control device for garbage clean combustion. The oxygen-enriched combustion system includes a burner 21, an auxiliary fuel The supply device 22, the oxygen supply device 23, and the ignition fuel supply device 24 are composed of the specific steps and methods:

[0030] 1. Put the stale garbage into the grate incinerator 1, and burn it in the drying section, combustion section and burnout section of the incinerator;

[0031] 2. The gaseous oxygen in the oxygen-enriched combustion system and the ignition fuel (such as fuel oil, gas, etc.) are fully premixed in the burner 21 to form a high-temperature fire core;

[0032] 3. ...

Abstract

The invention provides a stale refuse oxygen-enrichment high-temperature intelligent regulation and control incineration stabilization method and belongs to the field of refuse incineration. The method is characterized in that a grate incinerator and an oxygen-enrichment combustion system, wherein the oxygen-enrichment combustion system comprises a combustor, an auxiliary fuel supply device, an oxygen supply device and an ignition fuel supply device. The method has the beneficial effects that the oxygen-enrichment combustion system has the combustion stabilization effect on combustion of stalerefuse in the grate incinerator; the flame temperature and intensity and the rotational flow degree of fuel and the size of flames in the combustor are regulated and controlled through 3T+E; the internal temperature of the grate incinerator is increased; disturbance in the grate incinerator is enhanced; the staying time of flue gas in the grate incinerator is prolonged; generated harmful gas andsubstances are reduced; and high-efficiency clean combustion of the stale refuse is realized.

Description

technical field [0001] The method belongs to the field of garbage incineration, and specifically relates to a method for intelligently regulating and stably incinerating stale garbage with oxygen-enriched high temperature. technical background [0002] Given that the sanitary landfill method has the advantages of relatively mature technology, simple operation and management, large processing capacity, low investment and operating costs, and is applicable to all types of waste, it is also the most important municipal solid waste treatment method in my country at present. However, with the passage of time, the increase in waste production has led to prominent problems such as anti-seepage at the bottom of the site, leachate treatment, recycling of landfill gas, and increasingly precious landfill areas. Therefore, the demand for management of stale waste is imperative. These stale wastes are usually classified according to the category of material utilization. After treatment,...
