All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a slag hole spray device of a gasification furnace, referring to fig. 1, 2, 3 and 4, fig. 1 is a schematic diagram of the front structure of the slag hole spray device of the gasification furnace; FIG. 2 is a schematic view of the circular header of FIG. 1; FIG. 3 is a schematic top view of FIG. 2; fig. 4 is an enlarged schematic view of the male coupling boss of fig. 1. This gasifier slag notch spray set includes: the water spraying device comprises a circular header 10, lifting lugs 11, a nozzle 12, a steel wire mesh 13, a connecting pipe 14, an external threaded pipe joint 15, a pipe seat 16, a baffle ring 17, a sealing gasket 18, a hanging plate 19 and a water spraying header 20.
The top of the round header 10 is welded on a square pipe at the bottom of the slag hole of the gasification furnace through a hanging plate 19 fixed on a plurality of hanging lugs 11.
The bottom of the circular header 10 is uniformly provided with 16 nozzles 12, the nozzles of the nozzles 12 form an included angle of 5 degrees with the vertical direction, the nozzles are arranged in a counterclockwise direction, and the inner diameter of the nozzles 12 is 8mm.
A circle of steel wire mesh 13 is arranged at the periphery of the 16 nozzles, and the top of the steel wire mesh 13 is welded with the bottom of the circular header 10 through rib plates. The steel wire mesh 13 is 1000mm in height, the diameter of the steel wire is 4.5mm, the length and width of mesh eyes are 12.5mm, and the steel wire mesh 13 is made of stainless steel Incoloy825.
The outer side wall of the circular header 10 is uniformly distributed and connected with 3 connecting pipes 14, and the specification of the connecting pipes 14 is phi 57x5mm. An external thread pipe joint 15 is arranged at one end of the connecting pipe 14 far away from the circular header 10, and the external thread pipe joint 15 is connected with the water spraying header 20 through a pipe seat 16. The tube seat 16 is a saddle-shaped tube seat, the tube seat 16 is fixed on the joint of the water spray header 20 through the baffle ring 17 by the external thread tube joint 15, and the sealing gasket 18 is arranged between the baffle ring 17 and the tube seat 16.
The operation principle of the spraying device is as follows: the cooling water is led from the original water spraying header 20 at the upper part of the slag pool and is sprayed out evenly through the nozzles of the connecting pipe 14, the circular header 10 and the 16 nozzles 12, the cooling water forms a layer of even water film on the steel wire mesh 13, liquid slag is quickly condensed into solid state in contact with the water film and falls down along the steel wire mesh 13 and falls into the slag pool, the possibility of completely and effectively isolating the adhesion of the liquid slag and the water-cooling wall is achieved, the slag cannot be hung on the steel wire mesh, and therefore the phenomenon that slag is gathered between the lower edge of a slag hole and the water-cooling wall and is combined into a large block, and the situation of blocking a channel and crushing equipment is caused is eliminated.
