Crusting treatment method in urban garbage hazardous waste treatment system

Abstract

The invention discloses a crusting treatment method in an urban garbage hazardous waste treatment system. A smoke chamber slope, a throat, a tail chord and a top are all made of anti-crusting materials. Cement clinker comprises 72% of limestone, 16% of clay, 1% of iron ore, 7% of coal and 4% of oxide, wherein the limestone content in the cement clinker is reduced from original 74% to 72%, the claycontent is increased from 14% to 16%, and the 4% of oxides comprise MgO and SO3. The smoke chamber slope and a discharging support plate are additionally provided with air cannons, and the air cannonair pipes are aligned with the smoke chamber slope and the discharging support plate. The parts such as the smoke chamber slope, the throat, the tail chord and the top are made of the anti-crusting materials, so that the anti-crusting performance is improved; the air cannons are additionally arranged on the smoke chamber slope and the discharging support plate to purge generated crusts in time, and the crusts are prevented from becoming large; the ingredients are adjusted to improve the silicic acid rate in the clinker and prevent crusting.

Description

technical field [0001] The invention relates to the technical field of municipal garbage treatment, in particular to a method for treating crusts in a municipal garbage hazardous waste treatment system. Background technique [0002] With the improvement of living standards, the amount of garbage produced by people's living activities is also increasing, and the amount of garbage that needs to be disposed of is also increasing. Municipal waste includes food waste, general waste, construction waste and sweeping waste. [0003] A large amount of garbage will cause the following hazards: stacking will occupy cultivated land and pollute soil and crops; garbage will pollute groundwater or enter surface water through rainwater seepage, causing water pollution; garbage will generate a lot of heat during the process of decay, mainly ammonia, methane and Harmful gases such as hydrogen sulfide, if the concentration is too high, it will form a stench, seriously pollute the atmosphere, ...

[0003] A large amount of garbage will cause the following hazards: stacking will occupy cultivated land and pollute soil and crops; garbage will pollute groundwater through rainwater seepage or enter surface water, causing water pollution; garbage will generate a lot of heat during the process of decay, mainly ammonia, methane and Harmful gases such as hydrogen sulfide, if the concentration is too high, it will form a stench, seriously pollute the atmosphere, emit heat, and surround the city from the air; garbage will spontaneously ignite and self-explode, which is unsafe; a large number of bacteria will breed in garbage dumps, which will easily cause infectious diseases and endanger the human body healthy

[0004] At present, the cement kiln is used to co-process urban waste. When the cement kiln co-processes urban waste, the harmful substances circulating and enriched in the system will form crusts. Leading to a decrease in co-processing in cement kilns
