Problems solved by technology

[0004] The use of coal to support combustion can buffer the change in the calorific value of garbage and stabilize the combustion state, but the adjustment of the furnace temperature is slow, difficult to control, and the amount of coal used is large (more than 20%), and there are many factors such as coal stacking, pretreatment, transportation, metering, and transportation. Complicated and cumbersome equipment and increased management

Embodiment Construction

[0020] 1. Use a small amount of pulverized coal to mix in advance the domestic garbage that has removed recyclable materials such as steel, iron, non-ferrous metals and plastics, or input the furnace after synchronous metering and mixing (the pulverized coal dosage is 1-5% of the weight percentage of garbage, can be adjusted appropriately according to the situation);

[0021] 2. Collect the sewage (including the flushing water of garbage vehicles) from the garbage seepage storage pit in the sewage pool and filter it through the filtering facilities. The filtered sewage, emulsifier and oil are injected into the agitator according to the weight percentage of water of 1-5% and 30-70%, and emulsification is realized by the action of a special emulsification mill.

[0022] 3. The garbage and pulverized coal are mixed by the mixing device and sent to the boiler furnace for combustion.

[0023] 4. The emulsified oil is sent to the special casing nozzle through the gear oil pump with...

Abstract

The invention discloses a three-in-one garbage incineration method. The three-in-one garbage incineration method is characterized by being performed according to the following technological process: (a) pulverized coals are doped in garbage to be mixed for future use; and the doping quantity is 1-5% of the garbage by weight; (b) an emulsifying agent and oil are added in water to prepare emulsifying oil; and the adding quantities of the emulsifying agent and the oil are respectively 1-5% and 30-70% of the water by weight; and (c) the garbage containing the pulverized coals is fed into a boiler hearth for burning; and the prepared emulsifying oil is sprayed into the boiler hearth for burning.

Description

technical field [0001] The invention relates to a three-in-one garbage incineration method, which belongs to a garbage power generation boiler combustion system. Background technique [0002] Waste incineration, as an effective means to realize the reduction, recycling and harmless treatment of domestic waste, has been more and more widely used. Currently, there are mainly two types of furnaces for waste incineration: grate furnaces and fluidized bed furnaces. They all need fuel to support combustion. According to the characteristics of the furnace type, fuel oil (gas) is generally used as the combustion-supporting material of the grate furnace; coal is used as the combustion-supporting material of the fluidized bed furnace. [0003] Fuel oil (gas) has the advantages of fast combustion speed, stable combustion, convenient adjustment, and easy control of furnace temperature, etc., but its high combustion cost is about 10 times that of coal, which makes the system operatio...
