Description

Gasifier nozzle head protection architecture

Technical Field

The utility model relates to a gasifier technical field, concretely relates to gasifier nozzle head protection architecture.

Background

When the gasification furnace works, the whole burner is horizontally placed into the gasification furnace, 2 groups of corresponding burners are arranged in one gasification furnace for opposite spraying (four burners symmetrically arranged on the same horizontal plane are coaxially sprayed for working), entrainment can occur after oxygen and high-pressure coal slurry are sprayed by the burners (the entrainment can occur due to mutual collision of spraying and pressure suck back in the furnace after the materials are sprayed out under high pressure by the burners before the materials are sprayed out next time), the temperature of the materials for entrainment is about 1000-1300 ℃, the cooling water coils wound on the edges of the burners can be sprayed, the problem of leakage of the cooling water coils can be caused, CO generated in the gasification furnace can leak into a burner cooling water return separation tank at the moment, and an online alarm can occur by a CO alarm instrument arranged on the separation tank. The leakage of the burner cooling water coil causes high channeling and low channeling, and serious accidents such as coil burnthrough, synthesis gas leakage, burner flame spraying of the gasifier and the like can be caused seriously; the leakage of the burner cooling water coil can also lead to serious damage of the device, long downtime and maintenance time and other malignant consequences. During the preparation period of the drying furnace before the system is started, if the burner coil pipe leaks, the temperature in the gasification furnace does not rise, so that the gasification furnace chamber does not reach the feeding temperature, and the system cannot normally feed.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

Example 1

As shown in fig. 1 and 2, a gasifier nozzle head protection architecture, including nozzle body 1, cooling water coil 2, water inlet 3, return water mouth 4, water inlet 3 and return water mouth 4 link to each other with cooling water coil 2 respectively, and cooling water coil 2 twines and welds at nozzle body 1 front end, is equipped with fin 5 in nozzle head position, fin 5 is connected on nozzle body 1. And the fins 5 cover the connecting parts of the burner and the cooling water coil. Specifically, at nozzle head welded fastening 2 rectangular fins, rectangular fin is on a parallel with nozzle head terminal surface, and rectangular fin length is greater than the coil pipe external diameter, makes the material of resorption spout on the fin, protects the coil pipe not attached to by the resorption material, guarantees not to leak, and later stage only need regular inspection and change the fin just can.

Specifically, as shown in fig. 3, the fin 5 has an elliptical shape, and as shown in fig. 4, the fin 5 has a circular ring shape.

Specifically, still including the protective layer, the protective layer is located the surface of nozzle body 1, cooling water coil 2, water inlet and return water mouth. The protective layer is made of casting material. Because the whole of the burner is huge, when the burner is placed into the gasifier, the cooling water coil at the front end of the burner is inevitably collided, so that the coil is collided, deformed, leaked and the like, and before the burner is placed into the gasifier, castable is coated on the outer surface of the coil, so that the coil is prevented from being collided when the burner is placed into the gasifier in construction, and the castable placed into the gasifier is dropped to the bottom of the gasifier when meeting high temperature in a combustion furnace or burnt to ash and fly to extinguish when meeting high temperature. So that neither the slag falls on the furnace bottom nor the slag is burnt to be exhausted.

Specifically, the length of the protective layer is larger than or equal to the diameter D of the coil pipe of the cooling water coil pipe 2 wound on the burner body.

Specifically, the water inlet and the water return opening are distributed on two sides of the burner body in parallel.

Specifically, the material of the fin 5 is the same as that of the burner body 1, and both are the incinel 625.

Specifically, the fin 5 is an annular structure, and the outer diameter of the fin 5 is larger than the maximum diameter D of the coil.
