Incinerator (electronic, breeding, clothing)

The 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 coal, fuel oil, gas and other fuels to burn and carbonize the objects to be treated at high temperature to achieve the purpose of disinfection.

Introduction

The incinerator is a kind of high-temperature incineration of exhaust gas, waste liquid, solid waste: for example, toxic gas (paint exhaust), toxic rocket liquid fuel, medical waste, domestic waste, animal carcasses, etc., to reduce or reduce the number of quantitative It is a kind of environmental protection equipment, and at the same time achieves a product that utilizes part of the heat energy of the incineration medium. Divided into fixed incinerators and mobile incinerators .

Working principle: Garbage is sent to the drying bed of the incinerator through the automatic feeding unit for drying, and then sent to the first-stage grate, where it is volatilized and cracked at high temperature on the grate, and the grate is thrown under the impetus of the pulse air power device. The garbage is thrown into the next level of grate step by step, at this time, the polymer material is cracked and other substances are burned. It goes on like this until it enters the ash pit after burning out and is discharged by the automatic slag removal device. Combustion-supporting air is sprayed in through the air holes on the grate and mixed with the garbage for combustion, while making the garbage suspended in the air. The volatilized and cracked substances enter the second-stage combustion chamber for further cracking and combustion, and the unburned flue gas enters the third-stage combustion chamber for complete combustion; the high-temperature flue gas heats the steam through the heating surface of the boiler, and the flue gas passes through Let cool and drain.

Its advantages are:

(1) A wide range of waste disposal can handle industrial waste, domestic waste, hospital waste, waste rubber tires, etc.

(2) High thermal efficiency of combustion The thermal efficiency of normal combustion is over 80%, and the thermal efficiency of combustion is over 70% even for domestic waste with a lot of moisture.

(3) Low operation and maintenance costs Due to the adoption of many special designs and a high level of automation control, there are fewer operating personnel (only two people are required for one furnace including the ash removal personnel), and the maintenance workload is also less.

(4) High reliability After nearly 20 years of operation, the failure rate of this incinerator is very low, with an annual operation of more than 8,000 hours, and the general utilization rate can reach more than 95%.

(5) High emission control level Due to the use of secondary flue gas reburning and advanced flue gas treatment equipment, the flue gas has been fully treated. After long-term testing, the CO content in the flue gas emissions is 1-10 PPM, the HC content is 2-3 PPM, and the NOx content is 35 PPM, which fully meets the European and American emission standards. When the flue gas is burned in the secondary and tertiary combustion chambers, the temperature reaches 1000°C, and the residence time is more than 2 seconds, which can basically decompose dioxins. The content of dioxins in the flue gas is 0.04 ng/m3, which is much lower than that in Europe and the United States The standard is 0.1 ng/m3.

(6) The grate has a self-cleaning function under the purging of compressed air.
