Brown gas type integrated solid waste incinerator

Abstract

The invention relates to a brown air integrated solid waste incinerator, which lifts the solid waste via the feeding belt machine (11) to the waste feeding inlet (12) into the burning room (6); then fires the burning machine (5) while the generated smoke is fed into the secondary burning room (8); then fires the oil ejector (7) which can burn the air, brown air or the mixture between air and brown air; the burnt smoke will be fed into gas-gas heat exchanger (9); and discharges the tail gas. The invention has the characterized in that fully burning, less CO discharge as 5mg / NM3 which is less than national discharge standard, simplified process, reduced device, saved cost and the application for integrating incinerate system.

Description

1. Technical field [0001] The invention relates to a solid waste incinerator in the environmental protection industry, in particular to a Brown gas type integrated solid waste incinerator which introduces Brown gas for combustion support. 2. Background technology [0002] Traditional solid waste incinerators include hopper elevators, combustion chambers, burners, secondary combustion chambers, fuel spray guns, gas-gas heat exchangers, blowers, exhaust pipes, semi-dry spray acid removers, soda-dissolving tanks, soda-dissolving It consists of pumps, air compressors, chimneys and other components. The process flow is to lift solid waste from the hopper lift to the feeding port into the combustion chamber, ignite the burner, and inhale air to support combustion; The cooling water is circulated, hot air is introduced into the combustion chamber, and the smoke generated after combustion enters the secondary combustion chamber, and the fuel spray gun is ignited in the secondary com...

AI Technical Summary

Problems solved by technology

[0003] Traditional solid waste incinerators adopt the method of supplementing air, usually by controlling the oxygen content of the combustion chamber to achieve the purpose of incineration of the tail gas of the furnace body and the secondary combustion chamber, and the temperature of the tail gas in the secondary combustion chamber is basically maintained at 1100 Above ℃, the spray flame of the fuel spray gun is dark red, and the diameter of the combustion flame is small, the diffusion flame is long, the amount of fuel is large and the degree of cracking of the fuel is not high, and the combustion is insufficient, so there are many harmful components in the exhaust gas, which is harmful to air pollution. Moreover, the traditional incinerator has a long process flow, various equipment, loose layout, large floor area, and high tail gas treatment costs.
