Background technique
It is limited to the particularity of economic technology condition and silver furnace self structure, the waste heat boiler for silver furnace must be through special
Structure design, and since silver copper smelter is bulky, smelting system is complicated, not ready-made mature technology is for using for reference, pot
Furnace is under production at high load (high concentration oxygen, high feeding quantity) operating condition, and cigarette ash bonding is serious on side wall in boiler, boiler system
The continuous production at high load that not can guarantee silver copper smelter becomes and restricts the bottleneck problem that process system improves production efficiency.
Summary of the invention
It is an object of the invention to prior art system there are aiming at the problem that, providing one kind can effectively reduce silver copper metallurgy
The gas sealing system of furnace waste heat boiler water-cooling wall dust stratification, bonding.
For this purpose, the present invention adopts the following technical scheme: a kind of 1. reduction silver copper smelter waste heat boiler water-cooling wall dust stratifications,
The gas sealing system of bonding, which includes sequentially connected uptake flue, downward-flow flue, radiation chamber and convection current
Room, convection cell tail end are equipped with exhanst gas outlet, and implementation steps are as follows:
(1) pneumatics wind is transported to boiler uptake flue position by main pipeline, and installs stainless steel shut-off valve one,
Installation remote control liquid flowmeter one；
(2) it is controllable that high pressure is installed at the predetermined absolute altitude of boiler uptake flue, on both side plate pipe type water cold wall middle position
Spray gun and spray gun seat, spray gun are fixedly mounted, and obliquely, spray gun passes through metal hose and steel pipe and pneumatics wind main pipeline to spray angle
Connection, pneumatics wind main pipeline are connected with plant area's power center (PC) pneumatics air pipe network；
(3) draw two branch pipes from supervisor to connect with boiler uptake flue two sides spray gun, connection metal hose, two branch
Manage each installation stainless steel shut-off valve one；
(4) in the operation of boiler nominal situation, valve air-supply, adjustment supervisor's air quantity are opened, gas sealing system is started to work.
The outage presses controllable spray gun and spray gun seat to have controllable flow rate valve group, and the spray gun seat is set using inclined in type
Meter, spray gun are connect by metal hose and steel pipe with pneumatics wind main pipeline, and pneumatics wind main pipeline is and plant area's power center (PC) pneumatics
Air pipe network is connected.
The beneficial effects of the present invention are: contain by the flue gas that uptake flue enters downward-flow flue, radiation chamber and convection cell
Dust quantity is greatly lowered, and can be effectively reduced boiler water wall knot ash degree, reduces the deashing labor intensity of stoker personnel, improves
The production efficiency of boiler system.

Specific embodiment
A kind of gas sealing system reducing silver copper smelter waste heat boiler water-cooling wall dust stratification, bonding, the blowing area waste heat boiler
Including sequentially connected uptake flue 2, downward-flow flue 3, radiation chamber 4 and convection cell 5,5 tail end of convection cell is equipped with exhanst gas outlet, real
Apply that steps are as follows:
(1) pneumatics wind is transported at boiler uptake flue 2 by pressure-air supervisor 11, and is responsible in pressure-air
Stainless steel shut-off valve one, remote control liquid flowmeter one is installed on 11；
(2) pressure-air spray is installed at the predetermined absolute altitude of boiler uptake flue, on both side plate pipe type water cold wall middle position
Rifle 8 and spray gun seat 9, pressure-air spray gun 8 are fixedly mounted, and spray gun seat is designed using inclined in type, and obliquely, high pressure is empty for spray angle
Gas spray gun 8 is connected to pressure-air supervisor 11, and pressure-air supervisor 11 is connected with plant area's power center (PC) pneumatics air pipe network.；
(3) draw two pressure-air branch pipes 6 from pressure-air supervisor 11 and 2 two sides pressure-air of boiler uptake flue sprays
Rifle 8 connects, and is connected with metal hose 7, respectively installation branch pipe control valve 10 1 of two pressure-air branch pipes 6；
(4) in the operation of boiler nominal situation, valve air-supply is opened, adjustment pressure-air is responsible for 11 air quantity, gas sealing system
It starts to work.
The system is that high pressure draught is sprayed into boiler uptake flue 2, and injection direction flows to phase with uptake flue flue gas
Right, flue gas can be compressed in uptake flue by pressure-air, so that most of not sufficiently combusted in flue gas and be brought into rising
The soot dust granule of flue burns away to thawing, and fusant mutually adsorbs bonding and reaches constant weight, while in pressure-air
Fall after cooling lower solidification into burner hearth, after such process persistently carries out, by uptake flue enter downward-flow flue, radiation chamber and
The dust content of convection cell is greatly lowered, and can be effectively reduced boiler water wall knot ash degree, reduces the clear of stoker personnel
Grey labor intensity improves the production efficiency of boiler system.
