化學(xué)除油器是綜合了斜管沉淀器及機(jī)械澄清池的優(yōu)點(diǎn)的一種高效節(jié)能的降濁除油設(shè)備，已廣泛用于鋼鐵、石化、石油行業(yè)含油廢水處理。連鑄污水中主要含有氧化鐵皮和少量油脂，連鑄污水處理系統(tǒng)常用化學(xué)除油器用于去除水中的氧化鐵皮懸浮物和油脂。The chemical degreaser is a high-efficiency and energy-saving turbidity reduction and oil removal equipment that combines the advantages of inclined tube settlers and mechanical clarifiers. It has been widely used in the treatment of oily wastewater in the steel, petrochemical, and petroleum industries. The continuous casting sewage mainly contains iron oxide scale and a small amount of grease. The chemical degreasing device is commonly used in the continuous casting sewage treatment system to remove the suspended iron oxide scale and grease in the water.

    化學(xué)除油器構(gòu)造及工作原理

化學(xué)除油器是采用三合一技術(shù)理論而設(shè)計(jì)的，加有凝聚劑的原水經(jīng)管道混合器混合后，進(jìn)入三角形環(huán)形槽，同時(shí)環(huán)形槽中加油絮凝劑，然后由槽底配水孔流入第一反應(yīng)室，在第一反應(yīng)室與清水分離后回流的水流混合（回流量為進(jìn)水量的3.5倍，回流量可以通過(guò)調(diào)節(jié)機(jī)構(gòu)來(lái)控制），混合后的水通過(guò)葉輪提升至第二反應(yīng)室。The chemical degreaser is designed using the theory of three-in-one technology. The raw water with coagulant is mixed by the pipeline mixer and enters the triangular annular groove. At the same time, the oil flocculant is added to the annular groove, and then flows into the first through the water distribution hole at the bottom of the groove In the reaction chamber, the refluxed water after the first reaction chamber is separated from the clean water is mixed (the reflux is 3.5 times of the inlet water, and the reflux can be controlled by an adjusting mechanism), and the mixed water is promoted to the second reaction chamber through the impeller.

再沿傘形罩進(jìn)入斜管區(qū)分離，清水上升由集水槽流出設(shè)備外，回流水由回流 縫回到第一反應(yīng)室，池底排泥管定期排泥。 池頂安裝有攪拌機(jī)，起攪拌及提升作用。攪拌 機(jī)為擺線(xiàn)針輪減速機(jī)，再經(jīng)大小齒輪減速，帶動(dòng)攪拌軸，攪拌軸頂設(shè)有手動(dòng)葉輪升降機(jī)構(gòu)，能調(diào)節(jié)攪 拌軸上葉輪出水口大小，從而調(diào)整回流水量。Then it enters the inclined pipe area along the umbrella-shaped hood and separates. The clear water rises and flows out of the equipment from the sump, and the return water returns to the first reaction chamber through the return seam. The mud drain pipe at the bottom of the pool is regularly drained. A mixer is installed on the top of the pool for mixing and lifting. The mixer is a cycloidal pinwheel reducer, which is decelerated by large and small gears to drive the mixing shaft. The top of the mixing shaft is equipped with a manual impeller lifting mechanism, which can adjust the size of the impeller water outlet on the mixing shaft to adjust the return water volume.

    針對(duì)第二反應(yīng)室內(nèi)積泥問(wèn)題，采取了如下改造 措施。將油絮凝劑直接向下伸至第一反應(yīng)室，從而 使大顆粒污泥沉積于第一反應(yīng)室內(nèi)的污泥斗內(nèi)。在 第二反應(yīng)室中沉降的是小顆粒污泥，對(duì)第二反應(yīng)室 和攪拌機(jī)運(yùn)行的影響便可大為減弱。In response to the problem of mud accumulation in the second reaction chamber, the following renovation measures were taken. Extend the oil flocculant directly down to the first reaction chamber, so that large particles of sludge are deposited in the sludge hopper in the first reaction chamber. The small particles of sludge settled in the second reaction chamber, and the influence on the operation of the second reaction chamber and the mixer can be greatly reduced.

化學(xué)除油器出水問(wèn)題
    對(duì)于化學(xué)除油器的出水的問(wèn)題，可在其出水立管內(nèi)插入一跟排氣管，用以釋放隨水流中的空氣，破壞氣水混合流，則可以提高出水流速，出水管中央的旋渦也可基本不見(jiàn)。排氣管插入出水立管的深 度根據(jù)現(xiàn)場(chǎng)實(shí)際試驗(yàn)確定，以破壞出水旋渦為準(zhǔn)，管徑可取ＤＮ８０。實(shí)際應(yīng)用后，確實(shí)起到了效果，并且在排氣管頂有類(lèi)似小噴泉的現(xiàn)象。For the problem of the water output of the chemical degreaser, an exhaust pipe can be inserted into the water outlet riser to release the air in the water flow and destroy the air-water mixed flow, which can increase the water flow rate and the vortex in the center of the water outlet pipe. But basically missing. The depth of the exhaust pipe inserted into the water outlet riser is determined according to the actual field test, and is subject to the destruction of the water outlet vortex. The pipe diameter can be DN80. After actual application, the effect is indeed achieved, and there is a phenomenon similar to a small fountain on the top of the exhaust pipe.

泥斗排泥管積泥問(wèn)題
    對(duì)于泥斗排泥管積泥問(wèn)題。主要的技術(shù)措施是在排泥管上電動(dòng)排泥電動(dòng)閥前（電動(dòng)排泥閥與泥斗之間）的管道上外接一路沖洗水源。沖洗水源可為廠(chǎng)區(qū)工業(yè)水或回用水，供水的水壓應(yīng)在0.2Mpa以上。對(duì)于泥斗排泥管，定期采用沖洗水源進(jìn)行沖洗，從 而起到疏通淤堵的問(wèn)題。For the problem of sludge accumulation in the hopper pipe. The main technical measure is to connect a flushing water source to the pipeline before the electric mud discharge valve on the mud discharge pipe (between the electric mud valve and the mud bucket). The flushing water source can be industrial water or reused water in the factory, and the water pressure of the water supply should be above 0.2Mpa. For the sludge discharge pipe of the hopper, the flushing water source is used for flushing on a regular basis, so as to dredge the clogging problem.

排泥方式問(wèn)題

    化學(xué)除油器底部污泥斗排泥管上取消電動(dòng)蝶閥，改為采用電動(dòng)閘閥或球閥、截止閥等其他便于 調(diào)節(jié)流量的閥門(mén)，閥門(mén)的電動(dòng)執(zhí)行器采用調(diào)節(jié)型。每次排泥周期按如下程序控制：全開(kāi)閥門(mén)10ｓ左右，再將閥門(mén)處于1/2開(kāi)度10s左右，最后將閥門(mén)關(guān)閉。按此實(shí)施后，原先化學(xué)除油器開(kāi)關(guān)型的排泥方式轉(zhuǎn) 變?yōu)檎{(diào)節(jié)型的排泥方式。采取該技術(shù)措施后，可以有效提高化學(xué)除油器排泥含固率，同時(shí)減少化學(xué)除油器排泥時(shí)耗水量。 The electric butterfly valve is removed from the sludge discharge pipe of the sludge bucket at the bottom of the chemical degreaser, and the electric gate valve or ball valve, stop valve and other valves that are convenient to adjust the flow are adopted instead. The electric actuator of the valve adopts the regulating type. Each mud discharge cycle is controlled according to the following procedure: fully open the valve for about 10 seconds, then place the valve at 1/2 opening for about 10 seconds, and finally close the valve. After this is implemented, the original switch-type sludge discharge method of the chemical degreaser has been changed to a regulated sludge discharge method. After adopting this technical measure, the solid content of the sludge discharged by the chemical degreaser can be effectively increased, and the water consumption of the sludge discharged by the chemical degreaser can be reduced at the same time.
