Specific embodiment
Presently in connection with specific embodiment, the present invention is further illustrated.These attached drawings are simplified schematic diagram only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Fig. 1 Fig. 2, a kind of danger wastes incineration residue melting plant, including molten bath forms top combustion in molten bath
Chamber 1A and lower slurry chamber 2A is burnt, molten bath upper end is arranged bell 4, opens up feed inlet and smoke outlet on bell 4.Feed inlet includes original
Expect import 41, quartz import 42 and ingredient import 43.
Run-off 5 is formed on rear side of molten bath, forms spill cavity 5A, the bottom spill cavity 5A and lower slurry chamber 2A in run-off 5
It is connected, 5 upper end of run-off forms thick liquid discharge mouth；Multiple burning spray guns 3 are respectively arranged on the molten bath of top combustion chamber 1A surrounding,
In the nozzle alignment top combustion chamber 1A of each burning spray gun 3.Each burning spray gun 3 forms 2 round knots on the side wall of molten bath
Structure, burning spray gun 3 are tilted down setting on molten bath.Burning spray gun 3 is existing matured product, can be produced with existing patent
This spray gun described in (patent No.: 201620439301- is used for the spray gun of side-blown submerged combustion bath smelting device).Respectively
A 3 independent control of burning spray gun, the quantity that can be started by burner, regulates and controls the temperature of melting furnace；Burning spray gun 3 uses
Submerged combustion technology, molten slurry are heated to 1300 DEG C or more.
Molten bath includes upper pool body and lower pool body；Lower slurry chamber 2A is formed in lower pool body, lower pool body and run-off 5 are by brick heap
Block forms integral structure, includes internal layer body 21 and outer layer body 22, and internal layer body 21 is piled up by high chromium and magnesium brick, and outer layer is by high alumina
Refractory brick is piled up, and clay liner 23 is provided with below outer layer body 22.
The lower pool body and run-off 5 for pile up out by high chromium and magnesium brick and alumina firebrick, due to directly being contacted with molten slurry,
Itself has good fire resisting, corrosion resistance；, there is convex-concave slot in the longitudinal spliced face of chromium and magnesium brick, and adjacent fire resisting chromium and magnesium brick passes through convex
