Abstract
The invention relates to a chemical adding device for a bottom-blowing furnace waste heat boiler and a reducing furnace waste heat boiler. The chemical adding device comprises a bottom-blowing furnace waste heat boiler water inlet pipeline, a reducing furnace waste heat boiler water inlet pipeline, a chemical adding storage tank A and a chemical adding storage tank B. The chemical adding storage tank A is connected to the bottom-blowing furnace waste heat boiler water inlet pipeline through a pipeline A. The chemical adding storage tank B is connected to the reducing furnace waste heat boiler water inlet pipeline through a pipeline B. The pipeline A and the pipeline B are communicated through a communicating pipe and a balance valve. Free adjustment can be carried out according to the laboratory report of boiler water of the two waste heat boilers, operation is convenient, and the treatment pertinence of the water in the boilers is effectively improved.
Description
Technical field
The present invention relates to the water treatment of boiler, particularly a kind of chemicals dosing plant for bottom convertor and afterheat of reducing furnace boiler.
Background technology
The bottom convertor that lead smelt industry uses and reduction furnace, its exhaust chimney is all equipped with waste heat boiler, plays the effect that flue gas is discharged in cooling.Waste heat boiler is operated in hot environment, needs constantly toward supplementing water inside boiler.In order to prevent fouling, will put into some medicaments in the process of supplementing water, such as water softener, scale preventative etc. improve the quality of water to reach requirement.Two waste heat boilers are not or not same place, and the fume afterheat of bottom convertor and reduction furnace chimney is also different.Therefore two cover chemicals dosing plants are just configured with respectively by inlet channel respective boiler boiler water conditioning along with water enters together.And often overlap chemicals dosing plant and all need to add two or more chemical agents; And when stove aquation is tested, often occur that the stove aquation of two waste heat boilers tests data deviation excessive, as basicity is normal, phosphate radical is abnormal, is difficult to accurately carry out Reasonable adjustment to stove water.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of chemicals dosing plant for bottom convertor and afterheat of reducing furnace boiler, use this chemicals dosing plant, at will can adjust according to the result of laboratory test of two waste heat boiler stove water, operation is convenient, effectively improves the specific aim of boiler water conditioning.
Technical scheme of the present invention: a kind of chemicals dosing plant for bottom convertor and afterheat of reducing furnace boiler, comprises bottom convertor waste heat boiler inlet channel, afterheat of reducing furnace boiler water pipe, A dosing storage tank and B dosing storage tank; A dosing storage tank is connected on bottom convertor waste heat boiler inlet channel by A pipeline, and B dosing storage tank is connected on afterheat of reducing furnace boiler water pipe by B pipeline; It is characterized in that: A pipeline and B pipeline are by ganging up pipe and balanced valve is communicated with.
The present invention increases and gangs up pipe and balanced valve, gross investment about about more than 5,000 yuan on the former chemical feed pipe of A dosing storage tank and B dosing storage tank.Can carry out dosing flow according to the result of laboratory test of two waste heat boiler stove water to adjust arbitrarily, operation is convenient, reaches the pharmaceutical quantities changing and enter two waste heat boilers, effectively improves the specific aim of boiler water conditioning.Present invention achieves boiler water treatment regulation and control in waste heat boiler pot convenient, effective, timely, operation convenient utility is strong, makes waste heat boiler water stabilization, and minimizing material consumption is cost-saving and efficiency is high, reach and guarantee that boiler water quality is qualified stable, effectively improve the safe operation of waste heat boiler boiler.
