Discharge.
Invention content
, be costly and difficult to reach thorough complete treatment effect the problem of big for chemical enterprise wastewater treatment difficulty, this
Invention provides a kind of more burner top-jet-type water cooling wall-shaped coal gasification equipment that can recycle industrial wastewater and the work that gasifies
Skill.Have coal adaptability is wide, efficiency of carbon con version is high, single stove ability is big, Load Regulation it is elastic it is big, production run is stable, equipment is thrown
The features such as money is saved, the simple and environmentally-friendly performance of Maintenance and Repair is good.
To achieve the above objectives, the present invention takes following technical essential to be achieved：Fine coal charging, pressurization pure oxygen gasification,
Reuse industrial wastewater replaces part pure oxygen as gasifying agent, water-cooling wall reactor, more burner top sprays, water chilling process.
A kind of powder coal gasification furnace, including a pressure-bearing furnace body, one reactor isolated with water-cooling wall of furnace interior,
Down-comer, a slag bath being located at below reactor and the shock chamber being connect with reactor cinder notch.
Pressure-bearing furnace body epimere uses the ellipse head of flanged joint, is convenient for the integral installation of furnace interior part, upper end ellipse envelope
The head cover of head center setting flanged joint, head cover center location is waste water burner interface, in same circle around waste water burner
Three fine coal burner interfaces are evenly arranged on week, waste water burner and fine coal burner are all installed on head cover, respectively by Industry Waste
Water, oxygen and fine coal spurt into stove straight down.Below head cover in advance installation water cooling coil pipe by furnace high-temperature region and to hold
The lid that bears down on one is kept apart.
Gasification furnace inner upper space crosses high temperature of the region as reactor for coal gasification to occur using water-cooling wall
It reacts, the pin of protrusion is devised on tube wall with the silicon carbide refractory liner of fixed about 20 millimeters thicks on the inside of water-cooling wall.Water-cooling wall
Reactor lower central position crosses a cinder notch with water-cooling wall, high-temperature gas after gasification and is molten into the slag of liquid together
It flows downward into shock chamber from cinder notch by gravity.
It is connected using the down-comer of metal material between cinder notch and shock chamber, declines pipe diameter and be more than cinder notch diameter, decline
Pipe lower end is arranged dentalation and immerses slag bath liquid level or less.Down-comer top is arranged spraying ring pipe and is swashed by tangential direction penetrating
