Problems solved by technology

[0004] 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
[0005] The use of coal for 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

[0021] 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);

[0022] 2. Collect the sewage (including the flushing water of garbage vehicles) from the garbage leach 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 1-5% and 30-70% by weight of water, and emulsification is realized by the action of a special emulsification mill.

[0023] 3. The garbage and pulverized coal are mixed by the mixing device and sent to the boiler furnace for combustion.

[0024] 4. The emulsified oil is sent to the special casing nozzle through the gear oil pump with a frequency modu...

Abstract

A garbage triad incineration method, of the garbage power generation boiler burning system technical field, includes the following technical technological process: a. mix the garbage with powder coal, the quantity added is 1-5% of garbage; b. add emulsifying agent and oil into water to create emulsified oil, with the quantity added of emulsifying agent and oil whose weight are 1-5% and 30-70% of water; c, the garbage mixed with powder coal is transferred into a boiler furnace cavity, burning, meanwhile, the emulsified oil prepared is injected to the boiler furnace cavity, burning. The invention uses garbage as base stock,and garbage, oil, powder coal combustion method, combines the advantages of oil and coal oxidizer, does good to making use of garbage, reducing coal quantity, cost and second pollution, saving energy, compared to the present technology.

Description

technical field [0001] The invention relates to a three-in-one garbage incineration method, which belongs to the combustion system of a garbage power generation boiler [0002] technology field. Background technique [0003] Waste incineration has been more and more widely used as an effective means to realize the reduction, recycling and harmless treatment of domestic waste. At present, 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 aid of the grate furnace; coal is used as the combustion aid of the fluidized bed furnace. [0004] 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 s...
