Project: The annual output of 600 tons of amphoteric ionic starch graft polyacrylamide production workshop for design
Amphoteric ionic starch grafted polyacrylamide as a synthetic polymer flocculant, Not only would it remove suspended solids and colloid in waste water, but also it would remove the common flocculant than the scope -- Dissolved waste water. Therefore, gender starch graft in the treatment of polyacrylamide has broad application prospects
In this design, took use of starch, MAA, AM and DMDAAC as raw materials, urea, ammonium persulfate as the initiator, in the inverse emulsion polymerization environment and the product of gender-ion starch grafted polypropylene-ammonium. Reaction process, using ethanol and the use of kerosene recoverable through access to information, Ion pairs of gender-based starch grafted polyacrylamide production have a certain amount of understanding, completed the design of the production equipment selection and layout of the workshop. Finally, the mapping of the production process map material balance map, the map of major equipment, workshop floor plan, elevation and other workshops.
1. Design origin
This design is the design of chemical plant in Shenyang. That is, the design is a necessary route for the scientific research achievement transforms for the industrialization big production must pass through the way.
2. Design standard
This design has referred to below the national standard and the stipulation.
a. Production process dangerous material and harmful factor classification and code.（GB/T13816-1992）
b. Commonly used dangerous chemistry classified standard.（GB13690-1992）
c. Inpressure vessel chemistry medium model harm and explosion hazard degree classification (HGJ43-1991)
d. Factory fire protection stipulation (GBJ16-1987)
e. The sewage synthesis discharges the stipulation (GBJ8978)
f. The steel pins down the pressure vessel (GB150)
g. Shell type heat interchanger standard (GB151)
h. Craft system arrangement of equipment design stipulation (HG20570)
i. Chemical installment piping arrangement design stipulation (HG/T20549)
3.Principle of design and main design standard
Principle:
(1) Safe: In the chemical production the massive matter are flammable, explosiveor are virulent. Therefore, the design must fully consider each kind is obvious and the latent danger, the guarantee production personnel's health and the security.
(2) Ease of operation: While determines each production process and equipment, but also must reasonably determine the operating condition. Because of it to the production process and the equipment establishment and it’s the function display and the control plan determination, all has the direct relations.
(3) Investment province: Namely the request economically uses the equipment investment, the construction invests, the public project investment and the manpower cost.
(4) Is advantageous for the installment: The factory arrangement should satisfy the construction and the installment work request. Specially should consider the large-scale equipment the hoisting, in the factory the path pavement structure and the load standard and so on should satisfy the work the request.
Main design standard:
(1) standard of the calculation
600 tons of annual production, product purity was 99.5% Working days for 300 days each year, 60 days to repair the machine, motor 5 days.
Key words : amphoteric ionic; polyacrylamide; Graft Copolymer; Inverse emulsion
