Problems solved by technology

[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, making the system expensive to operate
[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 household 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 5-10% of the garbage weight percentage, 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 poured into the agitator according to the water weight percentage of 5-8% and 35-70%, 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 a fre...

Abstract

The invention discloses a waste incineration method. The method is characterized by the following process flow: a, mixing pulverized coal into waste and keeping the mixture for later use, the mixing amount of the pulverized coal is 5-10% by weight of the waste; b, adding an emulsifier and oil into water to prepare emulsified oil, the adding amounts of the emulsifier and the oil are respectively 5-8% and 35-70% by weight of the water; and c, sending the waste with the pulverized coal into a boiler furnace for combustion, and spraying the prepared emulsified oil into the boiler furnace for combustion. The purpose of the invention is to provide the waste incineration method which takes the waste as a base material, collects the advantages of the oil and the pulverized coal combustion-supporting material, turns the water into treasure, reduces the total amount of coal combustion, saves energy and reduces cost.

Description

technical field [0001] The invention relates to a garbage incineration method. 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 burning speed, stable burning, convenient adjustment, and easy control of furnace temperature, etc., but its high burning cost is about 10 times that of coal, which makes the operating cost of the system expensive. [0004] The use of coal for combustion can buffer the change in the...
