Description
Technical field
This utility model relates to High Temperature High Pressure gasification furnace field, specifically a kind of synthesis gas/steam co-producing gasification furnace.
Background technology
Existing gasification furnace internal layer generally uses refractory brick material, but refractory brick material is easy to wear, needs usually to carry out more
Changing, and cheap coal cannot be widely used, range of application is little.Additionally, the manufacture of refractory brick, install, maintain and change the most multiple
Miscellaneous, waste time and energy.It addition, existing gasification furnace uses the type of cooling of chilling ring, after Quench, synthesis gas is through waters, bottom, shock chamber
Cooling after, rise along down-comer outer wall and body of heater ring cavity, the top that synthesis gas causes shock chamber's liquid level is unlikely air-flow drum
During bubble, whole liquid level is produced excessive fluctuation, and cause a series of liquid level warning.This kind of type of cooling is by high-temperature nuclei
Gas is passed through shock chamber, directly contacts with chilled water so that be deposited in the bottom of shock chamber after the slag solidification carried secretly in air-flow, with
The synthesis gas of Shi Gaowen is also cooled down.But this kind of type of cooling falls at the bottom of shock chamber after contacting with synthesis gas due to chilled water
Portion, it is impossible to recycle, cause great waste heat to waste.
Summary of the invention
The problems that this utility model exists for existing gasification furnace structure, it is provided that a kind of synthesis gas/steam co-producing
Gasification furnace.
This utility model is achieved through the following technical solutions: a kind of synthesis gas/steam co-producing gasification furnace, including stove
Body, is opened in the upper and lower assembled nozzle of body of heater and waste water and dregs outlet respectively, and described furnace interior is from top to bottom divided into
Gasification section, radiant section and Quench section, be fixed with the gasification section being made up of membrane wall, stove by suspension hanger above furnace interior
Body is provided with and the membrane wall water inlet being connected inside membrane wall and membrane wall outlet；By fire door water-cooled above gasification section
Wall is connected with assembled nozzle, and lower section is communicated to radiant section by cinder notch water-cooling wall, solid by sidewall hanger in described radiant section
Surely having steam generator, this steam generator includes the water cold sleeve that some longitudinal directions are uniform, by fin phase between water cold sleeve
Connecting, body of heater is provided with and exports with the soda pop import being connected inside steam generator and soda pop；It is communicated to below radiant section swash
Cold section, the furnace body outer wall being positioned at Quench section is opened by syngas outlet.
This utility model uses membrane wall can effectively solve the liner of other forms such as refractory brick, joint as gasification section
About material cost, coal subject range width, it is possible to digestion high-sulfur, high ash, high ash melting point " three high " colm, reduce gasification
The use temperature of stove outer covering；And the steam generator of radiant section can effectively improve the conversion of synthesis gas waste heat, heat obtains
Reclaim, by-product high temperature and high pressure steam, effectively raise efficient energy conversion, reached making full use of of energy-saving and environmental protection, improve
In the service life of equipment, it is ensured that the safety of equipment, social benefit significantly improves, and expands the optimization choosing of case material simultaneously
Select scope, improve the use cycle of equipment.

Detailed description of the invention
A kind of synthesis gas/steam co-producing gasification furnace, including body of heater 1, is opened in body of heater 1 upper and lower assembled nozzle 2 He respectively
Waste water and dregs outlet 3, described body of heater 1 is internal is from top to bottom divided into gasification section, radiant section and Quench section, in body of heater 1
Being fixed with, by suspension hanger 4, the gasification section being made up of membrane wall 5 above portion, body of heater 1 is provided be connected internal with membrane wall 5
Membrane wall water inlet 6 and membrane wall outlet 7；It is connected with assembled nozzle 2 by fire door water-cooling wall 15 above gasification section, under
Side is communicated to radiant section by cinder notch water-cooling wall 8, is fixed with steam generator 9 by sidewall hanger 10 in described radiant section, should
Steam generator 9 includes the water cold sleeve that some longitudinal directions are uniform, is connected by fin between water cold sleeve, and body of heater 1 is provided with
The soda pop import 11 that be connected internal with steam generator 9 and soda pop outlet 12；It is communicated to Quench section below radiant section, is positioned at sharp
Body of heater 1 outer wall of cold section is opened by syngas outlet 13.
When being embodied as, body of heater 1 inwall being positioned at gasification section and radiant section is provided with thermal insulation layer 14.
Further, described membrane wall 5 inwall is lined with castable.
During use, water-coal-slurry and oxygen are sent in gasification furnace by assembled nozzle 2 by gasification furnace, and water-coal-slurry is passed through through burning
After complicated chemical reaction, producing crude synthesis gas, synthesis gas is entered in radiant section through cinder notch water-cooling wall 8 by membrane wall 5.Membrane type
Wall 5 and steam generator 9 manage interior internal flow for feedwater, water at membrane wall 5 by drum, owing to piping water distribution is uniform, logical
The thermal insulation layer crossed on membrane wall 5, castable and body of heater 1 inwall can be effectively protected the heat of burner hearth and the radiation of heat,
Making body of heater 1 shell amount of stored heat little, can shorten equipment and start and furnace outage time, case material domesticizes.Radiant section increases steam and sends out
After raw device 9, entering radiant section synthesis gas from gasification section and exchanged by the heat of steam generator 9, synthesis gas exchanges through heat
After entered follow-up system by the syngas outlet 13 of bottom, steam generator 9 can by-product high temperature and high pressure steam, heat is returned
Receiving, be effectively improved energy conversion efficiency, reduce energy consumption, investment cost reduces, and unitary device year increases benefit considerable, i.e. protects
The safety that gasification furnace equipment uses, has been improved the whole efficiency of coal gasification and the adaptability of coal.
