Embodiment Construction

[0021] The present invention will be described in detail below through specific embodiments.

[0022] A combustion control method in waste incineration treatment, an oxygen sensor 10 is installed on the flue gas pipe 6 between the flue gas outlet 5 of the second combustion chamber 17 provided in the incinerator and the induced draft fan 7, and the oxygen sensor 10 detects The oxygen content in the flue gas,

[0023] According to the index of the gas content, the opening and closing degree of the damper of the secondary air supply is controlled, and the air volume of the secondary air supply is adjusted to realize the control of the air supply so that the oxygen content detected by the oxygen sensor 10 is maintained at a volume fraction of 5-13%. At the same time, the induced draft fan 7 is controlled within the range of -1000 to -100 Pa according to the negative pressure value.

[0024] Described incinerator comprises furnace body 1, and the upper part of this furnace body 1 ...

Abstract

The invention belongs to the technical field of waste treatment and particularly relates to a burning control method for waste incineration. In an incinerator, an air supply monitoring sensor is mounted on a smoke pipeline which is between a smoke outlet of a second burning chamber and an induced draft fan, content of the corresponding gas in the smoke is detected by the air supply monitoring sensor, and the air supply is controlled according to a content index of the gas, and meanwhile the induced draft fan is controlled according to a negative pressure value. By the use of the burning control method, incineration effect of waste is excellent, and air supply is accurately monitored.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a combustion control method in garbage incineration treatment. Background technique [0002] Domestic garbage and medical waste not only destroy the ecological environment of the city, but also cause serious harm to human health. Therefore, the harmless treatment of medical waste has become an urgent problem to be solved. At present, waste treatment mainly adopts incineration technology or process disposal. [0003] The essence of the incineration process is to control the combustion. At present, the air supply for waste incineration only relies on the induced draft fan to form a negative pressure on the incinerator, and it is impossible to accurately control the timing and volume of the air supply. If there is too much air supply, the temperature will be lowered. It affects the decomposition of garbage, and the load of the fan is too large; if the air supp...
