The feedwater of detailed description of the invention a kind of zinc roasting relieving haperacidity, 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;
The remodeling method of roasting relieving haperacidity circulating pump room: connect a DN50mm pipeline on relieving haperacidity circulating-pump outlet main pipeline To roasting water cooling pond, it is achieved the moisturizing to roasting pond, use Valve controlling rate of water make-up;Install one at water supply pump and heat-exchanger pump to connect Pipe, in order to regulate the liquid level in hot and cold pond, overflows after preventing hot water water full;SO2The cooling water of blower motor winding is by producing The water that water supply network provides cools down, and its cooling backwater pipeline is connected with relieving haperacidity circulating water pool, it is achieved circulate relieving haperacidity The moisturizing in pond, the moisturizing of such circulating water pool no longer with intrinsic production feedwater piping, has only been cleared up at parking maintenance When needing behind pond toward pond water filling, just use this pipeline.The feedwater of improved sulfuric acid pump house, circulation are as shown in Figure 2.
Relieving haperacidity and firing cycles water system integration simultaneously use: roasting relieving haperacidity circulating pump room relieving haperacidity circulation and roasting follow Ring water system is two each independent cover systems.Roasting relieving haperacidity circulating pump room relieving haperacidity circulation and firing cycles water system Remodeling method: at relieving haperacidity water circulating pump outlet conduit, Φ 273 × 6 welded tube branch is installed and is connected with firing cycles water delivery side of pump Connect, Φ 250 butterfly valve and flowmeter control water yield size are installed;At heat-exchanger pump outlet conduit, Φ 273 × 6 welded tube is installed and branches to system Acid circulating water pool, makes the cooling backwater of inflow hot-tub without cooling tower, is pumped directly into relieving haperacidity circulating water pool, as shown in Figure 5.When When outdoor temperature is less than 10 degree, it is possible to stop water supply pump and roasting cooling tower electric machine, open and close control valve, by relieving haperacidity recirculated water Pump directly feeds roasting system cooling water, thus reaches the purpose of water-saving and electricity-saving.When environment temperature is higher than 10 degree, open and close control Valve, enables original system and supplies water.When roasting cooling tower have an accident short-term be difficult to recover when, enable this covering device, it is ensured that roasting Recirculated cooling water regular supply, is unlikely to impact and produces.
The transformation of Sulfuric Acid Circulation Pump room cooling column water receiver: originally used old-fashioned " V " type water collection device, water rate mistake of wafing High.Remodeling method will use " V " type water collection device at present, is replaced by " M " type high-efficient water-recovering device." M " heavy duty detergent assembly type is received Hydrophone, material is PVC, has the flame-retarding characteristic of resistance to combustion self-extinguishment;Planform is frame-type, receives water effect good;Meanwhile, this receipts water Device piece intensity is high, indeformable, easy to maintenance.
The moisturizing of described cleaning system, the transformation of drainage system: install in the outlet of diluted acid plate type heat exchanger circulating water pipeline A piece DN100mm pipeline is connected with gas colling tower filler, installs a DN50mm pipeline and Safety water seal filler simultaneously Connect, make the moisturizing of gas colling tower and Safety water seal be produced, by original, the outer draining that feedwater changes recirculated water into, when purifying system System discharges waste acid to environmental protection workshop, when the reduction of gas colling tower recycle acid liquid level needs to add water, and the moisturizing in tower with this pipeline, from And make the outer draining of relieving haperacidity circulation be recycled utilization.So can save about 400 tons of water every day.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, save a water, take following Measure: being further added by an oil cooler, former cooler is installed in series with oil, lubricating oil passes sequentially through two coolers and carries out cold But;In order to improve cooling effect, newly installed cooler uses a water, and water source is taken in peace one on motor cooling feedwater piping Root DN50mm arm, uses the Valve controlling water yield, and the backwater of cooler is connected to dry circulating slot technique of inhaling and adds water pipeline, as dry suction The technique moisturizing of regulation recycle acid concentration, reaches to save the purpose of a water;Circulating water pipeline and a waterpipe add communicating pipe, Switch over control with valve, it is achieved circulating water temperature relatively 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 needs to add water to regulate recycle acid concentration, and water is used averagely once a day The water yield about 80 tons, dry suction adds water 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 is connected with the dry technique pipeline that adds water of inhaling, adds water as dry technique of inhaling with cooler backwater, No longer add water from a grid, thus saved a water consumption.The feedwater of improved dry desorption system, recirculated water plane are such as Shown in Figure 10.
