A kind of feedwater of zinc roasting relieving haperacidity of embodiment, circulation, including relieving haperacidity roasting feedwater, recirculated water
System, the feedwater of cleaning system, circulation, the feedwater of sulfur dioxide unit, circulation, the feedwater of dry desorption system,
Circulation；
It is calcined the remodeling method of relieving haperacidity circulating pump room：A DN50mm pipeline is connect on relieving haperacidity circulating-pump outlet main pipeline
To roasting water cooling pond, the moisturizing to being calcined pond is realized, with Valve controlling rate of water make-up；Connected in water supply pump with heat-exchanger pump installation one
Pipe, to adjust the liquid level in hot and cold pond, prevent from overflowing after hot water water is full；SO2The cooling water of blower motor winding is by producing
The water that water supply network provides is cooled down, and its cooling backwater pipeline is connected with relieving haperacidity circulating water pool, realizes and relieving haperacidity is circulated
The moisturizing in pond, the moisturizing of such circulating water pool have only been cleared up no longer with intrinsic production feedwater piping in parking maintenance
When past pond water filling is needed behind pond, just using the pipeline.Improved sulfuric acid pump house feedwater, circulation are as shown in Figure 2.
Relieving haperacidity merges use with firing cycles water system：Roasting relieving haperacidity circulating pump room relieving haperacidity circulation and roasting follow
Ring water system is each independent two systems.It is calcined relieving haperacidity circulating pump room relieving haperacidity circulation and firing cycles water system
Remodeling method：It is connected in relieving haperacidity water circulating pump outlet conduit installation Φ 273 × 6 welded tube branches with the outlet of firing cycles water pump
Connect, the butterfly valves of Φ 250 and flowmeter control water size are installed；System is branched in the heat-exchanger pump outlet conduit installation welded tubes of Φ 273 × 6
Sour circulating water pool, the cooling backwater of inflow hot-tub is set to be pumped directly into relieving haperacidity circulating water pool, as shown in Figure 5 without cooling tower.When
When outdoor temperature is less than 10 degree, it is possible to stop water supply pump and roasting cooling tower electric machine, control valve is opened and closed, by relieving haperacidity recirculated water
Pump directly feeds roasting system cooling water, so as to reach the purpose of water-saving and electricity-saving.When environment temperature is higher than 10 degree, control is opened and closed
Valve, enable original system water supply.When accident, which occurs, for roasting cooling tower is difficult to recover in short term, the covering device is enabled, ensures roasting
Recirculated cooling water regular supply, it is unlikely to influence production.
The transformation of Sulfuric Acid Circulation Pump room cooling column water receiver：Originally old-fashioned " V " type water collection device was used, water rate mistake of floaing
It is high.Remodeling method is " V " the type water collection device that will be used at present, is replaced by " M " type high-efficient water-recovering device." M " heavy duty detergent assembly type is received
Hydrophone, material PVC, there is the flame-retarding characteristic of resistance to combustion self-extinguishment；Planform is frame-type, and it is good to receive water effect；Meanwhile the receipts water
Device piece intensity is high, indeformable, easy to maintenance.
The moisturizing of the cleaning system, the transformation of drainage system：Export and install in diluted acid plate type heat exchanger circulating water pipeline
A piece DN100mm pipeline is connected with gas colling tower filler, while installs a DN50mm pipeline and Safety water seal filler
Connection, the moisturizing of gas colling tower and Safety water seal is set to be changed to the outer draining of recirculated water by original production feedwater, when purification is
To unite and discharge waste acid to environmentally friendly workshop, gas colling tower recycle acid liquid level is reduced when needing to add water, the moisturizing into tower with the pipeline, from
And the outer draining of relieving haperacidity circulation is set to be recycled utilization.400 tons or so of a water can be so saved daily.It is improved
Polished feedwater, circulation are as shown in Figure 7.
The transformation on economy of water cousumption of sulfur dioxide unit：In order to solve the higher problem of bearing bush temperature, a water is saved, is taken following
Measure：An oil cooler is further added by, is installed in series with the former cooler of oil, it is cold that lubricating oil passes sequentially through two coolers progress
But；In order to improve cooling effect, the cooler newly installed uses a water, and water source, which is taken on motor cooling feedwater piping, pacifies one
Root DN50mm branch pipes, with Valve controlling water, the backwater of cooler is connected to dry suction circulating slot technique filler pipe road, as dry suction
The technique moisturizing of regulation circulation acid concentration, reaches the purpose for saving a water；Circulating water pipeline and a waterpipe add communicating pipe,
Control is switched over valve, realizes circulating water temperature compared with water supplement heat rejecter of Gao Shitong, and when one party breaks down
Complementation can be carried out when cutting off the water supply.Improved recirculated water, water supply system are as shown in Figure 9.
Dry desorption system transformation on economy of water cousumption：Dry desorption system is needed to add water to adjust circulation acid concentration, and average water once a day is used
80 tons or so of water, suction plus water are done all the time by grid supply of plant area.SO after transformation2Blower fan Lubricating-oil Station adds one
Oil cooler, oil cooler water return pipeline are connected with dry technique filler pipe road of inhaling, and add water by the use of cooler backwater as dry technique of inhaling,
No longer add water from a grid, so as to save a water consumption.Improved dry desorption system feedwater, recirculated water plan are such as
Shown in Figure 10.
