Potassium sulfate complete equipment produced by our company is the digestion and absorption of Mannheim roasting method, optimized and improved late-model reaction furnace, combined with other special equipment, successfully resolved the high temperature, high concentration of acid corrosion and continuously feed production and so on a number of technical problems, no waste water, no waste gas, and no waste residue is exhausted, various technical indicators have reached the the state environmental protection requirements.
The company developed reaction furnace which adopted special heat resistant, corrosion resistant alloy material and the size of appearance is DN6000 (mm), has reasonable design, advanced technology, service life of ten years. The reaction furnace could produced superior potassium sulfate about 40 - 43 tons everyday, has the characteristics of Saving coal, electricity, and manpower, high efficiency, no pollution etc...
Hydrochloric acid recovery system, which is independent research and development, has the advantages of simple process, convenient operation, low energy consumption, less investment, far less than traditional absorption equipment.
Technological innovation
1, Large output: A single can produce potassium sulfate product more than 40 tons daily. The reaction furnace is independent type, the support is in the middle of the insulation walls, and increases the heating area of the furnace body. Heat of combustion through the bottom, reaction furnace wall, and the top part, can pick-up to absorb heat farthest, and improves the utilization rate of the heat, the yield can be increased by more than 50% finally.
2, Low energy consumption: Because of the unique structure and excellent material of the reactor, that improves the utilization ratio of heat, and the quantity of the coal consumption is decreased by more than 40%.
3, Low power consumption, high output: A few reaction furnaces share a set of equipment, that reduce the consumption of the power.
4, Hydrochloric acid with high absorption efficiency:
The equipment is easy to operate, the hydrogen chloride gas from the top air outlet, through the suction channel inhalation absorption system, that reduce the intake of furnace dust. Hydrochloric acid absorption system uses polypropylene material, packed tower and graphite falling film absorber are used each other, finally improved the absorption efficiency and the cooling effect;
The tower body and circulated tank adopts separate layout, that increases the capacity of circulated tank, reduces the emission times of the finished acid, besides convenient operation, low price and convenient repair
5, The energy-saving and coal-fired stove instead of gas furnace:
Due to the unique structure and good thermal conductivity of the reactor, and the reactor adopts the new energy-saving and coal-fired stove to instead of gas furnace or other heating modes, the operation of the reactor is more simple, safe, low coal consumption, saves about 40% than coal gas furnace.
6, The stability of production:
The reaction chamber adopts the special proprietary materials which has the performance of high temperature resistant, anti acid, good diathermancy, and has the advantages of simple structure, firmness, high temperature resistance, corrosion resistance, good thermal stability, good thermal conductivity. At the same time, simple operation, repair rate is very low. The rake arm adopts materials of non-metallic, high temperature resistant and corrosion resistant to package, heat resistance, corrosion resistance, wear resistance, large mechanical bearing capacity; And the extension of the production cycle.
7, It reduced the cost of production greatly:
The production technology of potassium sulfate based on the improved Mannheim process, is better than the traditional production technology, can save the cost of 230 yuan per ton.
