Description
Technical field
The utility model relates to steelmaking equipment field more particularly to a kind of water treatment systems for converter dedusting line.
Background technique
The wet electric dust removing system of wet process is a kind of dust pelletizing system of newest minimum discharge applied to converter, the dust pelletizing system
In include Wet-electric duster.Wet-electric duster includes polar curve pole plate, atomizer and washes away nozzle, and atomizer uses
Clean circulating water (water of relative clean) is used as atomized water, for improving the quality of flue gas；It is (relatively dirty using turbid circulating water to wash away nozzle
Water) wash away polar curve pole plate, prevent polar curve pole plate accumulate dust.
According to pneumatic steelmaking experience, when turbid circulating water temperature is at 65 degree or more, polar curve polar board surface can accelerate fouling；50
When to 65 degree, polar curve polar board surface will be slow fouling；At 50 degree or less, the less fouling of polar curve polar board surface；In the prior art
In, turbid circulating water is a kind of cycling use of water, and over time, the bulk temperature of turbid circulating water is gradually increasing, it is easy to lead to pole
Fouling is serious on line pole plate, influences converter gas dust removing effects.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of water treatment systems of converter dedusting line, reduce polar curve
The fouling of pole plate.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of for converter dedusting line
Water treatment system, including settling tank, clean circulating water pipeline and turbid circulating water pipeline；
The first water inlet, the second water inlet and discharge outlet are provided on settling tank, the first water inlet connects the ash bucket of converter,
The dust washed away in the water mixed flue gas of polar curve pole plate flows into settling tank through ash flue bucket again；Second water inlet passes through tee pipe fitting
Make-up water pump and overflow pipe are connected, water can be added by make-up water pump when the water level in settling tank is too low, when the water level in settling tank
When excessively high, it is automatically drained out by overflow pipe；Discharge outlet is connected to by tee pipe fitting washes away nozzle and sewage treatment plant, in water pump
Under the action of, the water in settling tank constantly recycles；
Clean circulating water pipeline is passed through out of settling tank, clean circulating water piping connection to atomizer, clean circulating water in settling tank with
Heat exchange occurs for water in tank, takes away the partial heat of water in tank, reduces coolant-temperature gage.
Further, the clean circulating water pipeline in settling tank in the shape of a spiral, increase the heat exchange of water in clean circulating water and tank
Time.
Further, the bottom of the settling tank is provided with sewage outlet, is equipped with valve on sewage outlet；Work as settling tank
After the dust concentration of interior sewage reaches a certain level, valve discharge sewage can be opened.
Further, the quantity of the settling tank is multiple, is aloft connected between settling tank and settling tank, clean circulating water pipe
It is passed through out of all settling tank；Multiple settling tanks can further increase settling efficiency, at the same also can increase clean circulating water with it is turbid
The heat exchanger time of ring water.
The utility model has the advantages that the water treatment system of the present embodiment constructs heat exchanger using settling tank and clean circulating water pipe, using net
Ring water constantly takes away the heat of turbid circulating water, avoids coolant-temperature gage in tank excessively high, reduces or remove the fouling on polar curve pole plate, improves
The efficiency of dust collection of converter dedusting line.
