Heat pipe heat exchanger inside the activity of financial benefits in alumina production
Production of activated alumina working with the prevalent aluminum hydroxide as raw supplies, ready by Flash-calcining ?? aluminium. ?? is used as higher quality refractories, alumina production shape of activated alumina refractory fiber and its principal raw material. For Flash-calcining furnace and inside the production course of action of spherical alumina flow activated heat supply for a organic gas-fired roaster oven, are heat power units. Exhaust gas processing is for Flash-calcining furnace ahead of adoption of bag dust collector to drain, high-temperature exhaust heat loss and pollute the environment. A lot of waste heat from flue gas recycling is critical to power consumption. Gas-gas heat pipe heat exchanger made use of for Flash-calcining operation of high temperature flue gas heat, swapped out heat for preheating of aluminum ball activated prior to roasting. Application of heat-pipe heat exchanger increases output for Flash-calcining, and lessen gas consumption.
Economic benefits
Following you install the heat exchanger initial statistics single about 0. six t/d, heat hot air is utilized for preheating body activation of activated alumina, activated firing natural gas consumption is lowered eight.7m3/h. Industrial all-natural gas value is two.95 Yuan/M3, sales earnings by 300 Yuan/t of activated alumina, industrial electrical energy by 0.5 Yuan/kW*h, projects with a total investment price of 70,000 yuan.
15 depreciation of plant assets, depreciation:
Seven-fifteenths = year of 4,700 Yuan/a heat exchanger maintenance (by expense coefficient is 0. 13 dollars):
7 x 0. 13 =0. 910,000/a
Net profit for the year:
28.6-0.47-0.91-4.75=22.47 million/year
By way of practice proved, pipe heat exchanger of application on activity alumina production heat recycling applying is successful of, on boost activity alumina merchandise of integrated rewards effect is obviously, but production run within the also discovered has some issue, as activity alumina aluminum Flash speed roasting of flue gas containing dust volume larger, alumina particles on pipe put on extra heavy effects hot for using life, for remedy this issue can and heat exchanger companies go over in flue gas imports side for pipe enhanced anti-mill nursing w and for infiltration aluminum processing, in elevated for pipe Put on resistance has achieved fantastic outcomes following employing heat superior. Application of heat pipe heat exchanger in Al2O3 for production of activated alumina's power consumption to create a contribution.
