The spray gun adopts a single support structure and is fixed by a spray gun base, and the free end of the spray gun is supported on a spray gun bracket; the spray gun base adopts the bevel connection form, and the spray gun bracket adopts the recess face structure, and the spray gun can remove in the recess, and recess preset position is provided with the nozzle and reserves the breach to realize nozzle screens fixed function.
A method for overhauling a spray gun outside a desulfurizing tower of the device comprises the following steps: in the process of equipment maintenance, firstly, fixing bolts outside a spray gun base are removed, a spray gun is rotated, the spray gun is taken out through the assistance of a spray gun bracket, a spray gun base opening is sealed, the spray gun is maintained, the spray gun base opening is opened, the liquid spraying end of the spray gun is placed into the spray gun bracket, the spray gun is pushed to a mounting position, the spray gun is rotated to be in place, and the spray gun is fixed on the spray gun base through the bolts.
Compared with the prior art, the invention realizes the function of independently taking out any spray gun for maintenance under the condition of no system or equipment shutdown when the spray gun or the nozzle has a fault and needs to be overhauled by using the spray gun clamping and fixing mode of the spray gun bracket, thereby realizing the aim of online overhauling. Meanwhile, the spray gun base adopts an inclined flange connection mode, so that interface liquid drops can automatically flow into the desulfurizing tower, the aim of preventing corrosion of equipment is better fulfilled, the workload of equipment maintenance is reduced, the working time and the service life of the equipment are prolonged, and the purification efficiency and the working efficiency of the equipment are better improved.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
The labels in the figures are: the method comprises the following steps of 1-casing, 2-flue gas inlet, 3-liquid discharge port, 4-flue gas outlet, 5-demister, 6-spray gun, 7-spray gun bracket, 8-ladder stand, 9-maintenance platform, 10-annular water supply pipe, 11-spray gun base and 12-glass flake.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The spray gun 6 of the invention adopts a single supporting structure and is fixed by a spray gun base 11, and the free end of the spray gun 6 is supported on a spray gun bracket 7; the spray gun base 11 adopts an inclined opening form, so that interface liquid drops can automatically flow into the desulfurizing tower, and the aim of corrosion prevention of equipment is better fulfilled; the spray gun bracket 7 adopts a groove surface structure, the spray gun 6 can move in the groove, and a nozzle reserved notch is arranged at the preset position of the groove, so that the function of clamping and fixing the nozzle can be realized.
