興昌機(jī)械曼海姆法硫酸鉀生(shēng)産裝置工(gōng)藝特點

Process characteristics of mannheim potassium sulfate production unit of Xingchang Machinery

我公司采用的硫酸鉀成套設備采用曼海姆工(gōng)藝，在德國(guó)幹式陪燒法的基礎上(shàng)加以改進而成的新型燃燒反應爐，與其它專用設備結合，成功的解決了高(gāo)溫、高(gāo)濃度強酸腐蝕以及連續化投料生(shēng)産等多(duō)項工(gōng)藝技(jì)術(shù)問題。與傳統工(gōng)藝相(xiàng)比主要有以下(xià)優點：

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:

• 産量大

單台日産硫酸鉀成品大于40噸反應爐爐體采用獨立式反應爐，支撐在保溫牆之間，根據反應爐的結構用耐火材料将反應爐依次分為(wèi)爐頂、爐壁、爐底三個(gè)受熱部分，使爐體的受熱面積大大增加，提高(gāo)了熱量的利用率。來自(zì)節能(néng)燃煤爐的熱量依次經過爐頂、爐壁、爐底，使熱量盡量被反應爐吸收，提高(gāo)爐體内原料的反應量從(cóng)而使産量大大提高(gāo)。

1. 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.

二、耗煤量低(dī)

由于反應爐的結構和材質使熱量利用率大大增加，因此使煤的消耗量大大降低(dī)。

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.

三、耗電(diàn)量低(dī)

采用兩台反應爐共用一(yī)套配套設備、一(yī)套吸收裝置的設備配置，使耗電(diàn)量大大降低(dī)。每兩台反應爐的生(shēng)産裝置用電(diàn)量（不包括備用設備）約230KW/時。

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).

四、鹽酸吸收效率高(gāo)

操作方便鹽酸吸收系統采用聚丙稀材質，填料塔和石墨降膜吸收器(qì)相(xiàng)間使用，提高(gāo)了吸收效率和降溫效果；塔體和循環儲槽采用分離式布置，增大了循環儲槽容量，減少成品酸排放(fàng)次數，方便操作且價格低(dī)維修方便；循環泵采用直連式離心泵，使用壽命長(cháng)，維修保養方便；反應爐和吸收設備間的吸氣管道采用耐高(gāo)溫耐腐蝕材質砌成，使用壽命長(cháng)，減少維修清理次數，這是碳化矽反應爐所不能(néng)實現的。

4. 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.

五、采用節能(néng)燃氣爐代替煤氣發生(shēng)爐

由于本反應爐的受熱特點，可以采用新型的節能(néng)燃氣爐來代替煤氣發生(shēng)爐或其它加熱方式，使操作更加簡單、安全，比煤氣爐省煤20%左右。這是碳化結構的爐子不可能(néng)做到(dào)的。

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.

六、生(shēng)産穩定，操作方便

本反應爐采用特種材質制造，具有結構簡單堅固，耐高(gāo)溫，耐腐蝕，熱穩定性導熱性能(néng)好，而且操作簡單，維修率極低(dī)。爐内攪拌系統使用壽命在2年(nián)左右，大大降低(dī)了維修成本，延長(cháng)生(shēng)産周期。

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.
