Description

Three-phase multi-functional mixed combustion furnace

Technical field

The invention provides a kind of three-phase multi-functional mixed combustion furnace, belong to industrial burner technical field.

Background technology

In the combustion furnace of chemical fields such as fixed bed semiwater gas, great majority are the waste gas burning stove, occur the combustion furnace of gas, solid cofiring in recent years, i.e. solid contents such as combustion furnace bottom fire coal or cinder, top combustion gas.Though this combustion technology is immature, but still solved simple fuel gas buring stove, made the halfway phenomenon of fuel gas buring in the combustion furnace because of heat source insufficiency.Yet modern enterprise is comprehensive enterprise mostly, outside removing exhaust gas, the waste residue, also has a lot of waste liquids, and particularly the waste liquid of most high heating value or high pollution brings tremendous economic loss and environmental pollution for enterprise and society.

Summary of the invention

The object of the present invention is to provide a kind of three-phase multi-functional mixed combustion furnace that can overcome above-mentioned defective, on the basis of coal-fired slag and waste gas, can also burn high heating value waste liquid, excellent working performance.Its technical scheme is:

Comprise main burning furnace coal-fired and combustion waste gas, the bottom of main burning furnace is provided with air compartment, the upper surface of air compartment is an air distribution plate, be evenly equipped with blast cap on the air distribution plate, the fire coal district, middle and lower part of main burning furnace burner hearth tilts or vertically is provided with the many water pipes that circulate with extraneous formation water, the burner hearth middle part is provided with the burning shower nozzle, exhaust gas inlet place on the sidewall of main burning furnace middle part is provided with mixed burner, it is characterized in that: set up secondary combustion furnace, the top of secondary combustion furnace tangentially is communicated with main burning furnace through flue, the top of secondary combustion furnace is provided with waste-liquor burner, and the bottom is an ash hole, and the sidewall of middle and lower part has heat outlet.

Described three-phase multi-functional mixed combustion furnace, air compartment are provided with air inlet and the manhole of connecting air blast, and the fire coal district of main burning furnace is provided with mechanical coal feeder mouth and manhole.

Described three-phase multi-functional mixed combustion furnace, the many water pipes that coal-fired district tilts to bury underground are 20 °~45 ° angles with level, and every water pipe all circulates with external world's formation water, is used to reduce chamber temperature, prevents coking.

Described three-phase multi-functional mixed combustion furnace, the furnace wall of main burning furnace and secondary combustion furnace and the sidewall of flue are provided with three layers from the inside to surface: the shell that flame retardant coating, heat-insulation layer and steel plate are made.

Described three-phase multi-functional mixed combustion furnace is equipped with venting on the sidewall of the middle and lower part of main burning furnace and secondary combustion furnace.

Its operation principle is: mixed combustion furnace is established main burning furnace and secondary combustion furnace, main burning furnace is used for reference the fluidized bed furnace structure, and air distribution plate is established in the bottom, blast cap is used for coal-fired slag, and distinguishes the water pipe of burying underground with extraneous circulation at the middle and lower part fire coal, water pipe is used to reduce chamber temperature, prevents coking; Exhaust gas inlet is established at the middle part, but middle part and top hollow, so that sufficient combustion space to be provided; The autonomous upper furnace side of gas fume after burning goes out, and goes into from secondary upper furnace tangential side again, forms eddy flow; The waste-liquor burner that is used for the waste liquid atomizing is established in center, secondary combustion furnace top, and the waste liquid after the atomizing at high temperature gasifies, and burns.The high-temperature flue gas that the common burning of ternary fuel is produced after bottom dedusting in secondary combustion furnace, the slagging-off, enters heat reclaim unit by heat outlet in the lump, carries out heat recovery.

The present invention compared with prior art has following advantage:

1, not only can burn to cinder, waste gas, the high temperature that can also utilize its burning to be produced burns waste liquid, has realized that really the gas, liquid, solid three-phase replenishes the good situation of utilizing, burning jointly together mutually;

2, sufficient combustion, after measured, the fixed carbon content of carbon containing waste residue burning back residue enters the flue gas of secondary combustion furnace, every 10000Nm in 2.2~4% scopes 3Just can burn the 1000Kg waste liquid, and secondary combustion furnace outlet measures imflammable gas, combustion rate improves 8~10% than ordinary combustion stove, and combustion furnace resistance ratios ordinary combustion stove reduces 800Pa;

3, this combustion furnace can solution-air, gas-solid, liquid-solid pair of combined burning use, also burning gases or solid-state coal and cinder separately, excellent working performance.
