那么海沙脫鹽設(shè)備-海砂除氯設(shè)備是如何除鹽工作的?通過供水系統(tǒng)連續(xù)不斷注入淡水,對(duì)含有鹽分的海沙進(jìn)行不斷沖洗,降低海沙的氯離子含量,然后使含鹽水從分離筒低端口溢出,完成去鹽工作。
如何檢測(cè)海砂除鹽效果?我國檢測(cè)海砂是否合格常用的方法有物理檢測(cè)法和磨粉檢測(cè)法。 國家的施工質(zhì)量標(biāo)準(zhǔn)國家標(biāo)準(zhǔn)《建筑用沙GB/T14684-2001》、《混凝土質(zhì)量控制標(biāo)準(zhǔn)(GB60164-92)》,以及建筑行業(yè)標(biāo)準(zhǔn)《普通混凝土用沙質(zhì)量標(biāo)準(zhǔn)及檢驗(yàn)方法(JGJ52-92)》、《建設(shè)部關(guān)于嚴(yán)格建筑用海沙管理的意見(建標(biāo)[2004]143號(hào))》等相關(guān)文件
那么海沙脫鹽設(shè)備-海砂除氯設(shè)備有哪些種類呢?
1.鏈斗式海沙脫鹽設(shè)備
優(yōu)點(diǎn):生產(chǎn)能力大,每小時(shí)清洗海沙可達(dá)350-400噸,能耗低,淡水用量少,淡化劑跟氯離子轉(zhuǎn)換率高,淡化后的海沙氯離子含量穩(wěn)定,部分廢水可以循環(huán)利用,設(shè)備使用壽命長、穩(wěn)定性和連續(xù)工作能力強(qiáng)。
缺點(diǎn):設(shè)備基礎(chǔ)前期投資大,場(chǎng)地面積占用大,前期需要建造2-3個(gè)掏斗池,易損件需要周期性更換。
1. chain bucket sand washing equipment
Advantages: high production capacity, up to 350-400 tons per hour cleaning sand, low energy consumption, water consumption, desalination agent with high conversion rate of chlorine ion, chlorine ion content of sand stability after desalination, wastewater can be recycled, long service life, stable and continuous working ability.
Disadvantages: large investment in equipment foundation, large occupation of the site area, the need to build 2-3 early excavation pool, wearing parts need periodic replacement.
2.輪式海沙脫鹽設(shè)備
優(yōu)點(diǎn):設(shè)備節(jié)能,前期投資少,維修率低,對(duì)場(chǎng)地要求低(平整即可)
缺點(diǎn):除氯效果差,細(xì)沙流失多,淡水消耗大。
2. wheeled sand cleaning equipment
Advantages: equipment energy saving, early investment, low maintenance rate, low requirements on the site (leveling can)
Disadvantages: the effect of chlorine removal is poor, the sand loss is more and the consumption of fresh water is large.
3.螺旋式海沙脫鹽設(shè)備
優(yōu)點(diǎn):設(shè)備能耗低,用淡水少,淡化效果好,淡化后的海沙指標(biāo)穩(wěn)定。
缺點(diǎn):處理能力低,設(shè)備投資大。
3. spiral sand washing equipment
Advantages: low energy consumption, less water desalination, good effect, stable index after desalination of sea sand.
Disadvantages: low processing capacity and large investment in equipment.
