Abstract
The invention discloses a rotary kiln refuse incinerator and a method for eliminating harmful gas generated from incinerated refuse. Refuse added with pulverized lime is sent into a rotary kiln from a refuse feed port and is then ignited, and a blower is used for providing air for refuse combustion. Fuel gas is pressurized through a fuel gas compressor, then the pressurized fuel gas is sent into a fuel gas pipe, is sprayed out from a fuel gas discharging nozzle above the inside of the rotary kiln and is then ignited for assisting refuse combustion, and a fuel gas blast blower is used for providing air for fuel gas combustion through an air inlet pipe. An electromotor drives the rotary kiln to rotate on a support table, and the refuse and the pulverized lime are taken to a high position by ribs in the rotary kiln and are then dumped, thereby increasing the contact area of the ignited refuse and the air, simultaneously forming acidic harmful gas generated from the pulverized lime and the incinerated refuse to generate a chemical reaction, and eliminating the harmful gas. The refuse discharged from the rotary kiln is roasted and slagged by fuel flames sprayed out from a fuel nozzle arranged below when passing through a furnace rake, and then flows out from a refuse slag outlet, and tail gas is used for firing a boiler after processed through a tail gas incinerator.
Description
Technical field
The present invention relates to the method for a kind of rotary kiln refuse incinerator and elimination harmful gas generated from incinerated refuse.
Background technology
The structure and the principle of existing rotary kiln refuse incinerator are as follows: rotary kiln is low early and high after, and rubbish is from the back side top of the rotary kiln rotary kiln of packing into, and the motor drives rotary kiln rotates on brace table, and the rubbish in the rotary kiln is moved forward; At the front end of rotary kiln, fuel pump is extracted the heavy oil in the fuel tank out the pressurization back and is lighted when fuel nozzle sprays into rotary kiln, and the fuel oil air blast provides air for heavy oil combustion, and pressure fan provides air for the further abundant burning and the incineration firing of heavy oil.In the process that rubbish moves forward in rotary kiln, through oven dry, low-temperature burning, high-temp combustion, last roasting slag making, the rubbish slag flows out from slag notch.Tail gas is separated big molecular gas through cyclone separator, carries out second-time burning before sending into the heavy oil flame of rotary kiln front end, and low weight gas is discharged from chimney through induced-draft fan pressurization back.
This kind rotary kiln refuse incinerator has a lot of shortcomings: at first be that efficiency of combustion is low, just rubbish can not burn at short notice, produces a large amount of heats and is used for burning boiler, and the steam of generation is used for generating.Next is to contain a large amount of pernicious gases in the flue gas.Rubbish is when oven dry and low-temperature burning, volatilization and decomposite a large amount of pernicious gases, and cyclone separator is difficult to these gases are all separated, still have a large amount of dioxin and deleterious acidic gases such as sulfur dioxide, nitrogen dioxide in the flue gas, we can remove these deleterious acidic gas with lime, but can't remove the nitric oxide that produces in this way in the thermal-flame of heavy oil.
The method of eliminating deleterious acidic gas has dry type pulverized limestone method and wet type lime water law, just allows flue gas pass through pulverized limestone or limewash, allows sour gas and lime generation chemical reaction, generates harmless solid calcium salt.
The method of eliminating dioxin has heating: flue gas is heated to more than 800 degree, allows dioxin at high temperature decompose.Burning method: allow flue gas lead to the flame of incinerator, allow flame that dioxin is lighted, burn into micro-molecular gas.
The method of more than eliminating pernicious gas all is to handle afterwards, and just the harmless treatment of the flue gas that produces burning away the refuse needs special equipment, and wants consumes energy and other materials.
Summary of the invention
The method of rotary kiln refuse incinerator of the present invention and elimination harmful gas generated from incinerated refuse can overcome above shortcoming.
Rotary kiln refuse incinerator of the present invention is burned device and is formed by gas compressor, gas valve, gas blowing engine, Gas Pipe, blast pipe, pressure fan, garbage inlet, rotary kiln, motor, brace table, fuel tank, fuel pump, fuel oil air blast, fuel nozzle, furnace rake, the outlet of rubbish slag, tail gas.Rotary kiln is installed on two brace tables, preceding high back is low, the motor drives rotary kiln rotates, there is garbage inlet the top that the rotary kiln front end is equipped with between pressure fan, pressure fan and the revolution sky, many row's fins are arranged on the rotary kiln inwall, there is the blast pipe that Gas Pipe is housed in the pipe to enter and pass the interior top of described rotary kiln, the downside of the blast pipe in the rotary kiln has row's aperture, the nozzle of Gas Pipe stretches out from the aperture of blast pipe, and the space between the nozzle of Gas Pipe and the blast pipe aperture is the outlet of the wind of blast pipe.Downside is equipped with furnace rake outside the rear end of rotary kiln, and furnace rake is tilted to down, and there is fuel nozzle the below of furnace rake.The back lower place of furnace rake is the outlet of rubbish slag, tail gas is housed in the flue of the back upper place of furnace rake burns device, and a heat(ing) coil that adds hot water is being twined in the outside of rotary kiln.Heat(ing) coil is made up of water inlet pipe, water inlet band, intake chamber, water inlet strip of paper used for sealing, heating tube, effluent trough, water outlet strip of paper used for sealing, water outlet band and outlet pipe, intake chamber and effluent trough are two grooves around rotary kiln that a segment distance installs of being separated by in described rotary kiln outside, be stamped a circle water inlet band and a water outlet band respectively at intake chamber with above the effluent trough, be pressed with a water inlet strip of paper used for sealing respectively on the both sides of water inlet band, on the water inlet band water inlet pipe that is connected with intake chamber be housed; The both sides of water outlet band are pressed with a water outlet strip of paper used for sealing respectively, and the outlet pipe that is connected with effluent trough is housed on the water outlet band.A heating tube is being twined in rotary kiln outside between intake chamber and effluent trough, and the water inlet pipe of heating tube and effluent pipe mouth are connected with intake chamber and effluent trough respectively.
