Transformation of ammonia Ⅱ mud recovery system
Capacity of 38kt / a, Ⅱ mud recovery of ammonia as a belt filter system. After the expansion of water due to Hou system with vacuum filter recovery efficiency is low, the reasons for higher costs, ammonia recovery mud I lay, I mud ammonia directly into the sewer. As the last decade the company continued on innovation and technological innovation, production capacity has reached l80kt / a, increased emissions of ammonia I mud, resulting in increased product costs, while the sewage outfall of water and ammonia, chlorine, with no increase in root In order to reduce costs, increase efficiency, reduce pressure on sewage treatment, the company decided I mud couplets for recycling alkaline ammonia. I l ammonia necessary for mud recovery 1.1 ammonia and ammonia Ⅱ I muds mud economic losses caused by emissions from July 2004 under the Technological Check data,[link widoczny dla zalogowanych], soil emissions of nitrogen per day I 50m. , Slurry solid to liquid ratio (dry soil layer) l0, serum 9O, year by 345 days per year for the emissions caused by the loss of 3,671,300 yuan. (Prices for 2004 product sales and the purchase price). 1.2 The direct discharge of ammonia I mud caused by environmental pollution is serious, the company's total sewage outfall excessive ammonia and chlorine roots, to the great difficulty of treatment. 2 rehabilitation programs through the mud on the determination of ammonia Ⅱ, Ⅱ Gold of the group of ammonia in the 10 ~ 1OOum mud between particle size, ammonia I mud (dry basis) in l5m. / D, through the filter with a number of manufacturers producing advice, use the box is now fully automated production of ammonia I filter mud recycling company to meet the requirements. Transformation process is as follows: j?} Process Description: From the bottom of the barrel clear of ammonia emissions from slurry Ⅱ (solid to liquid ratio l0, flow of 30m / h) by the ammonia Ⅱ mud pump pressure,[link widoczny dla zalogowanych], the pressure increased to 0.4 0.6MPa into the box after the filter, the filter within the solid Received date: 2006 One of a O5 O6 liquid separation. Back to clarify the supernatant after the separation barrel; filter box full of mud cake pressure,[link widoczny dla zalogowanych], after pressure dry phase, the cake moisture content down to 35 below, the following automatically unloaded into the filter funnel, transported by the car outside the factory. Automatic dumping time is generally 30 ~ 40rain (including cleaning cloth time), mud pie to finish unloading, start the filter pump, filter plate after the opening of ammonia Ⅱ pressed mud pumps into the next cycle, class unloading mud again. Equipment Selection 3 3.1 Pursuant to the amount of ammonia containing mud and mud conditions I choose the LU East Laiwu Coal Mine Machinery Factory automatic box-type filter of a filtration area of 340m,[link widoczny dla zalogowanych], filter chamber volume of 5m. . 3.2 According to box-type filter on the inlet pressure requirements and ammonia I mud erosion and corrosion of the pump distinctive features, select a plant in Shandong Zibo slurry flow l5 ~ 50m. / H, the slurry head 40 ~ 70m 2, opening and equipment, slurry pumps with 37.5kw motor. To facilitate the work of the cake pull operation, making a 3.5m high steel platform, filter installed in the steel platform, the platform produced a lower set of 6 clay funnel. 4 Implementation of the project in 2004 to start construction in January l2, 7 January 2005 production debugging, January l0 day turned into a normal operation. Transformation to achieve the desired goal, to eliminate the ammonia efflux I mud. Meanwhile, to clarify the barrel due to increased excretion of A Ⅱ mud, so to clarify the bucket overflow turbidity Ⅱ ammonia decreased from the previous fall to around 200ppm 10O ~ 120ppm, so soda water insoluble product decreased, improved product quality, the following data quality can explain the changes. !!!!!!!!! 20030.090.090.090.090.090.090.090.090.090.090.090.0920040.090.090.090.090.090.090.090.100 .100.100.100.1020050.080.060.050.050.040.040.040.040.040.050.040.04 data in the table in units of 5.1% 5-benefit analysis of investment of 700,000 yuan to the project , the annual recovery of ammonia I mud 17250m, reduce costs 3.67 million, compared with the direct benefits achieved, payback of 2.5 months, 300 million in additional benefits. 5.2 to achieve significant environmental benefits, reduced efflux. 5.3 improve product quality and increase competitive advantage. 6 after the implementation of the project other problems with 6.1 United alkaline balance is an important associated factor in the production of alkali, the project's successful operation must be linked alkaline balance as a prerequisite and guarantee, or can not fundamentally solve the energy saving problem. 6.2 Quality of raw salt, ammonia Ⅱ mud turbidity, especially water-soluble impurities on the ammonia Ⅱ mud turbidity greater impact, to improve product quality and stability, but also guarantee the quality of raw materials.
