Liyang Xingchang Machinery Co., LTD. Mannheim method production line advantages

Process characteristics of mannheim potassium sulfate production unit of Xingchang Machinery

The potassium sulfate complete set of equipment adopted by our company adopts Mannheim process and is improved on the basis of German dry combustion method. The new combustion reactor, combined with other special equipment, has successfully solved a number of technological problems such as high temperature, high concentration of strong acid corrosion and continuous feeding production. Compared with the traditional process, it has the following advantages:

A.Big output

A single potassium sulfate products more than 40 tons reactor furnace adopts independent type reactor, support between thermal insulation wall, according to the structure of the reactor with refractory reactor in turn divided into roof, furnace wall, furnace bottom three heated parts, makes the hot area of the furnace body greatly increased, improve the utilization rate of the heat. The heat from the energy-saving coal-fired furnace passes successively through the top, wall and bottom of the furnace, so that the heat is absorbed by the reactor as far as possible, and the reaction amount of raw materials in the furnace body is improved so that the output is greatly increased.

B.Low coal consumption

Because of the structure and material of the reactor, the utilization rate of heat is greatly increased, so that the consumption of coal is greatly reduced.

C.Low power consumption

Two reactors share a set of auxiliary equipment, a set of absorption device equipment configuration, so that the power consumption is greatly reduced. The production unit of each two reactors consumes about 230KW/ h of electricity (excluding backup equipment).

D.Hydrochloric acid absorption efficiency is high

Easy to operate hydrochloric acid absorption system adopts polyacrylic material, packed tower and graphite falling film absorber alternate use, improve the absorption efficiency and cooling effect; The tower body and circulating tank are arranged separately, which increases the capacity of circulating tank, reduces the number of acid discharge of finished products, and is convenient for operation and maintenance with low price. Circulating pump adopts directly connected centrifugal pump, long service life, convenient maintenance; The suction pipe between the reactor and the absorption equipment is made of high temperature and corrosion resistant material, which has a long service life and reduces the number of maintenance and cleaning, which can not be achieved by the silicon carbide reactor.

E. The use of energy saving coal stove instead of gas producer

Because of the heating characteristics of the reactant furnace, the new energy-saving coal-fired furnace can be used to replace the gas producer or other heating methods, so that the operation is more simple and safe, and the coal consumption is low, the coal quality requirements are low, than the gas furnace about 20% of the coal. This is not possible with a carbonized furnace.

F. Stable production and convenient operation

The reactor is made of special materials, with simple and solid structure, high temperature resistance, corrosion resistance, thermal stability and thermal conductivity, and simple operation, low maintenance rate. The service life of the stirring system in the furnace is about 2 years, which greatly reduces the maintenance cost and prolongs the production cycle.
