Waste incinerators are widely used

Garbage incinerator is a kind of harmless treatment equipment commonly used in the harmless treatment of medical and domestic waste and animals. Its principle is to use the combustion of coal, oil, gas and other fuels to incinerate and carbonize the objects to be treated at high temperature to achieve the purpose of disinfection treatment.

In order to solve the problem of irritating flue gas and carbon black pollution, the first measure taken is to increase the incineration temperature to 700 °C, and later further to 800~1100 °C. At that time, people already knew the influence of the amount of combustion air and the input method on the flue gas temperature, so measures such as raising the chimney and configuring the supply fan and induced draft fan were successively adopted to increase the ventilation volume and meet the demand for the amount of combustion air in the incineration process. After the chimney is heightened, it also solves the problem of diffusion of irritating harmful substances in the flue gas. The world's Taiwan solid waste incineration equipment was born in Europe during the second technological revolution. By the second half of the 19th century, Paddington, England, had developed into a densely populated industrialized city. In 1870, a waste incinerator was put into operation in the city of Paddington. At that time, the waste had a large moisture and ash content, so it had low calorific value and was difficult to incinerate, so the incinerator was in poor condition and soon ceased operation. In response to the problem of poor quality of garbage and the difficulty of incineration, a double-layer grate (a strong burning coal seam on the lower grate) was adopted, and then in 1884, an attempt was made to co-burn the garbage with coal to improve the combustion characteristics of garbage fuel. However, neither attempt yielded satisfactory results, and the low chimney caused the nearby environment to be polluted by irritating fumes. Waste incineration is suitable for domestic waste, medical waste, general industrial waste (general industrial waste adopts high-temperature combustion, secondary oxygenation, automatic slag discharge high-tech measures to meet the monitoring requirements of sewage discharge), etc.

Compared with landfill and composting, waste incineration is more land-efficient and does not cause surface water and groundwater pollution. With the acceleration of urbanization and the near-limit of construction land indicators, waste incineration has gradually become a realistic choice for large and medium-sized cities in the central and eastern regions with dense population, land shortage and garbage siege. Garbage incinerators

The garbage incinerator is a device that incinerates and disposes of garbage, the garbage is burned in the furnace, becomes exhaust gas and enters the secondary combustion chamber, which is completely burned under the forced combustion of the burner, and then enters the spray dust collector, and is discharged into the atmosphere through the chimney after dust removal. The garbage incinerator is composed of four systems: garbage pretreatment system, incineration system, smoke biochemical dust removal system and gas generator (auxiliary ignition incineration), which integrates automatic feeding, screening, drying, incineration, ash cleaning, dust removal and automatic control.

Since the type and composition of waste can vary greatly depending on the region and season, the waste incineration equipment must have good fuel adaptability. In this regard, the technical measures taken at that time were the addition of a waste drying area in the incinerator and the preheating of combustion air.
