Tubular reactor and pre-and in the comparison tank reactor technology


Maintained at about 1.4 to maintain the solubility of ammonium phosphate of Sheng Tai, the product water from the pipe reactor granulator,[link widoczny dla zalogowanych], granulating machine in accordance with appropriate adjustments to the granulation. Grain production in order to achieve the requirements of the final N / P,[link widoczny dla zalogowanych], will be making the rest of the ammonia sticking out of solid material inside the nozzle under the bed to join. Granulator the f1 exhaust venting through the two after washing liquid; export gas dryer dust first group by the cyclone, and then into the second washing liquid, washing the exhaust vent. Phosphate absorption in which a washing most of the ammonia gas, sulfuric acid washing the secondary absorbed ammonia, washing liquid into the granulator after the recovery of tubular reactor. Therefore, the process has the advantages of liquid does not emit pollution. Since the】 990 sets of equipment put into operation since December, more than two years of comprehensive experience in the production units, the sets of production equipment can be summarized as _F1. Make good use of the thermal phosphoric acid, sulfuric acid and ammonia and in response only carried out the tubular reactor, the reaction heat is used to vaporize almost all the material in the water,[link widoczny dla zalogowanych], which avoids the traditional method of heat loss to the outside world. 2. High efficiency granulator used to replace the pipe reactor and in pre-groove, its length 5.9m, diameter of ten 0.122m, 48.4 aspect ratio, Reynolds number of approximately quasi-1.3x10. Granulator tubular reactor can be l993 Jing four years and spread manure as fertilizer almost plug-flow type, while the pre-and slot in the stirred tank reactor, basically. Thus,[link widoczny dla zalogowanych], in the same flow rate and yield, the pipe reactor and the required volume in the tank than the pre-small, thus saving materials and construction costs. 3. System and the material easy to maintain heat balance pipe reactor operating conditions for the t pressure 0.5-0.8MPa, temperature 120 ~ 160 ℃, the slurry water content is very low, the surface and are of pre-atmospheric pressure in the operation, and requires transmission,[link widoczny dla zalogowanych], so its final moisture content in the slurry 18 to 20. Therefore, the pipe reactor process of granulation of the water balance is very favorable. Week granulator silver export of materials with low moisture (<2) it is possible to achieve without the dry production process, and because less liquid, required to maintain the solid volume of grain has been greatly reduced. As mentioned above, the traditional method of returning to 1 ratio, (4-6), face the process of return ratio of 1: (2-2.5). 4. Abolished the reaction slurry delivery system directly within the tubular reactor, the slurry spray directly onto the material bed granulator, and therefore, without jurisdiction of the feed slurry, eliminating the slurry pump and the corresponding pipeline, metering device to make the investment cost reduction. 5. Unit cost reduction due to production of high (65-70t / h), surface equipment and the size is only pre-production of equipment in the taxi a ÷, therefore, depreciation, reduced power consumption of fuel and other expenses. 6. Conducive to environmental protection throughout the production system is a closed loop type, no waste, gas emissions, thereby protecting the environment, save the environmental aspects of the investment. 7. High utilization of raw materials, the obtained particle size (on the next page 60) Table 4 on the Japanese economy benefits Ao chant modified impeller impellers l l a direct result of the reform and open ttI ... ...

In view of the tubular reactor process the outstanding merits of the complex world countries have invested in Taiwan Fertilizer manufacturers transform the original use of the traditional process pipe reactor technology. China should catch up, trying to phosphate and compound fertilizer production technology to achieve the international advanced level. Round one to save money more than 10,000 yuan. Step back when they cut a lot of maintenance work. Analysis and transformation of the actual use prove t extraction slurry pump impellers and related components are necessary and simple. As part of the pump impeller and its related transformation, the pump failure rate significantly reduced. The last 3 years, I plant a single super-power to complete the design task to create the conditions for ammonium phosphate production.
