Abstract
The invention provides a method for purifying circulating water in a smelting furnace. When the circulating water is circularly used and generates foams, deionized water is added to a circulating water inlet, wherein the use amount of the deionized water is 5-10% of the total use amount of the circulating water. The method for purifying the circulating water in the smelting furnace has the advantages that the operation is simple, the cost is low, the purification effect is good, and the use time of the circulating water can be prolonged, so that the use cost of the smelting furnace is reduced.
Description
Technical field
The present invention relates to water-treatment technology field, especially relate to a kind of method purifying smelting furnace internal recycle water.
Background technology
Cooling circulating water is the major portion of smelting furnace, and traditional smelting furnace cooling circulating water circulates in ruhmkorff coil, water power cable, can generate a large amount of foreign ions and foam, and smelting furnace induction coil can make to form incrustation scale in recirculated water.Foam and incrustation scale can make cooling performance reduce, thus make coil surface working temperature too high, power consumption is increased, even causes local superheating, burn out coil and cause the accident.In addition, on the impact of copper pipe behaviour in service very greatly, it directly changes the working temperature of copper pipe for foam and incrustation scale.
Even if installed antisludging equipment in circulating water system additional, the incrustation scale in water coolant can be removed, but but cannot have been removed foam.Common practices often changes recirculated water, but large-scale smelting furnace requires very large to the consumption of recirculated water, and frequent recirculated water of changing can cause very large waste, improves production cost.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides a kind of smelting furnace circulation water purification method.Present method is simple to operate, with low cost, good purification, can extend the duration of service of recirculated water, thus reduces the use cost of smelting furnace.
Technical scheme of the present invention is as follows:
A kind of smelting furnace circulation water purification method, when recirculated water recycles generation foam, adds deionized water in the ingress of recirculated water; The consumption of described deionized water is 5 ~ 10% of whole recirculated water consumption.
The technique effect that the present invention is useful is:
The present invention does not need scale remover or the defoamer of raw material complex and expensive, only need add deionized water, can eliminate the foam in recirculated water, makes recirculated water can multi cycle 5 ~ 8 times, saves a large amount of Municipal Sewage for Circulating, reduces production cost.
Embodiment
Embodiment 1
For the body of heater cooling system of smelting furnace, start to produce foam when cooling circulating water recycles 3 times, now add deionized water in the ingress of recirculated water; The consumption of deionized water is 5% of whole recirculated water consumption.After interpolation, the removal of foam in recirculated water, can continue circulation 5 times.
Embodiment 2
For the body of heater cooling system of smelting furnace, start to produce foam when cooling circulating water recycles 3 times, now add deionized water in the ingress of recirculated water; The consumption of deionized water is 8% of whole recirculated water consumption.After interpolation, the removal of foam in recirculated water, can continue circulation 7 times.
Embodiment 3
For the body of heater cooling system of smelting furnace, start to produce foam when cooling circulating water recycles 4 times, now add deionized water in the ingress of recirculated water; The consumption of deionized water is 10% of whole recirculated water consumption.After interpolation, the removal of foam in recirculated water, can continue circulation 8 times.
Claims (1)
1. a smelting furnace circulation water purification method, is characterized in that, when recirculated water recycles generation foam, adding deionized water in the ingress of recirculated water; The consumption of described deionized water is 5 ~ 10% of whole recirculated water consumption.
