The technical solution adopted by the present invention to solve the technical problems is, including following methods:
A, new sustained release antisludging agent is researched and developed;
Compatibility is carried out by organic phosphoric acid, polymer, zinc salt etc., is examined using medicament synergistic effect of the research technique to compatibility
It examines, explores its scale inhibition sustained release performance, formulate the technology path of composite drug development, determine its compatibility ingredient;New sustained release resistance
The compatibility of dirty agent is always formulated 15%, acid aminotrimethylene phosphoric acid (ATMP) Zhan for 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP) Zhan and is always formulated
8%, phosphoryl hydroxy acid copolymer (POCA) Zhan is always formulated 8%, acrylic acid-sulfonic acid copolymer Zhan and is always formulated 8%, maleic-acrylic acid
Copolymer (MA/AA) Zhan, which is always formulated -1,2,4 acid tri hydroxy acid (PBTCA) Zhan of 5%, 2- phosphate butane and is always formulated 5%, zinc sulfate, to be accounted for
Total formula 5%, water Zhan are always formulated 46%;
B, it formulates recirculated water high concentration ratio and runs control strategy, recirculated water concentration rate is increased to 6 times by existing 3 times;
C, new sustained release antisludging agent is added in the recirculated water after improving concentration rate;
It can be realized by above-mentioned technological means with 2 300wm units, for quantity of circulating water 30000T/H × 2, recirculated water concentration times
Rate is increased to 6 times by 3 times, and rate of water make-up can reduce 210 ton/hours, can be calculated with 5000 hours with unit year, can be water-saving
1050000 tons/year, it can be calculated with 5000 hours with unit year, 1050000 tons/year of blowdown flow rate can be reduced simultaneously.
The beneficial effects of the present invention are: recirculated water is concentrated the method for the reduction thermal power plant recirculated cooling water utilization rate
Multiplying power is increased to 6 times by 3 times, cooperates the New Cycle water anti-incrustation corrosion inhibitor of research and development, has reached water conservation, high-efficiency sustained-release, resistance
Dirt prevents to corrode the beneficial effect that leakage causes the hidden danger of compressor emergency shutdown due to condenser tube materials;With 2 300wm units, circulation
For water 30000T/H × 2, recirculated water concentration rate is increased to 6 times by 3 times, and rate of water make-up can reduce 210 ton/hours, with machine
Group year can be calculated with 5000 hours, can be 1050000 tons/year water-saving, can use calculating in 5000 hours with unit year, can the row of reduction simultaneously
1050000 tons/year of dirt amount.
