The Shandong gold sea heavy industry science and technology limited company new Mannheim stove our company produces the new Mannheim furnace body, is the digestion absorbs the Mannheim method of roasting, the optimized improvement new reactor, used technologies and so on appropriation material, the success solves the furnace body thermostablly, has borne the question which the highly concentrated strong acid corroded, achieved without the waste water, does not have the waste gas, the non-waste residue discharge, each technical specification met the country environmental protection requirements. The new Mannheim law potassium sulfate production craft, may produce the brand-new fertilizer type potassium sulfate, the hydrochloric acid and so on, has the energy consumption lowly, the output high, the craft advanced, the product purity high, the conversion rate high, the production efficiency high, the operation then characteristics and so on easy, domestic origination. The company develops the development the reactor to use specially heat-resisting, the corrosion-resistant alloy material, the outlook size is DN6000(mm), the design is reasonable, the craft is advanced, the service life above for 8 years, daily production excellent potassium sulfate 40-43 ton/, has the province coal, the province electricity, the province manpower, highly effective, does not have characteristics and so on pollution. Researches and develops voluntarily the hydrochloric acid recovery system, the craft is simple, the ease of operation, the energy consumption low, invests few, is lower than the traditional absorption equipment by far. First, economy, energy conservation, environmental protection: Our company researches and develops the heat installation uses conserves energy the coal-burning stove, heating ways and so on substitution producer gas generator, the direct coal-burning heats, invests, the operation few simplifies, the energy conservation environmental protection. May several improvement Mannheim stove use in common a set of hydrochloric acid recycling installment, saves the coal, the province electricity, the province manpower, the odd-numbered days readies the materials (potassium chloride) to measure for 33-35 ton/day, may produce the potassium sulfate 40-43 ton, the annual production potassium sulfate 12000 tons - 13500 tons, the hydrochloric acid 14000 tons - 16000 tons. The traditional potassium sulfate production installment (silicon carbide reactor) the single Taiwan batch feeding (potassium chloride) measures for 20-21 ton/day, may produce the potassium sulfate for 24-26 ton/day, yearly produces 7000-7500 ton. Second, craft innovation 1, the output is big: The single Taiwan daily production potassium sulfate end product is bigger than 40 tons, the reactor is the free standing reactor, supports among the heat preservation wall, increased the furnace body heating area.The burning quantity of heat after the reactor furnace bottom, the fire walls, the furnace top part, maximum limit absorbs the quantity of heat, raised the thermal use factor, makes the output to enhance above 50%. 2nd, the energy consumption is low: As a result of the reactor unique structure and the fine material quality, raised the thermal use factor, the coal-burning consumption reduced above 40%. 3rd, the power consumption low, the output is big: The multi-Taiwan reactor uses in common set of supplementary equipment, reduced the power consumption. 4th, the hydrochloric acid absorption efficiency is high: The equipment ease of operation, the Hydrogen chloride gas by the furnace top air outlet, the process suction passage inspiration absorption system, reduced in the stove the dust soakage.The hydrochloric acid absorption system used gathers the third thin material quality, the absorption chamber and the graphite falls the membrane absorber to use mutually, enhanced the absorption efficiency and the temperature decrease effect; The tower body and the circulation storage tank use the separation formula arrangement, has increased the circulation storage tank capacity, reduces the end product acid emissions number of times, facilitates the operation also the price low service is convenient; The circulating pump uses the straight company -like centrifugal pump, the service life is long, the service maintenance is convenient; Inspiration pipeline between the reactor and the absorption equipment uses the thermostable anti-corrosive material quality to build, the service life is long, reduces the service cleaning up number of times. 5th, uses conserves energy the coal-burning stove to replace the producer gas generator: As a result of the reactor unique structure and the good heat conduction performance, use the new energy conservation coal-burning stove to replace the producer gas generator or other heating way, the operation are simple, are safe, the coal consumption is low, compares the gas stove province coal about 40%. 6th, stabilization of production: Responded the furnace body uses thermostable, the anti-strong acid, the thermal conductible good appropriation material manufacture specially, the structure is simple, reliable, thermostable, anti-corrosive, the thermostability is good, the heat conduction performance is good.The concurrent operation is simple, the service rate is extremely low.The rake arm uses the nonmetallic thermostable anti-corrosive material package, heat-resisting, corrosion resistance, wearability, the mechanical carrying capacity is big; Lengthened the production cycle. 7th, the production cost reduces greatly: After the improvement Mannheim law production potassium sulfate craft, surpasses the traditional production craft, each ton may save about the cost 230 Yuan. Third, the technical process and the design shows 1, the flow chart 2, technical process showing ①Uses in producing K2O≥50% agriculture to use the potassium sulfate and HCL≥31% technical grade hydrochloric acid: Uses raw material for the potassium chloride (K2O≥60%) and the strong sulfuric acid (H2SO4≥98%), with calcium carbonate neutral half-finished product in residual sulfuric acid. ②Potassium chloride and in strong sulfuric acid investment high temperature reactor, in 550℃ the furnace bottom agitation, the response, agitation at the same time the response material toward the eversion, arrives the reactor discharge hole time, the strong sulfuric acid and the potassium chloride responded finished, the potassium chloride and the strong sulfuric acid transformed the potassium sulfate and the HCl gas. The potassium sulfate after discharge hole chiller cooling, takes along by the transportation to the smashing system, joins the right amount calcium carbonate powder during transportation by the neutral potassium sulfate in the residual sulfuric acid; After after the smashing potassium sulfate enters the packing system, (the general 50kg/bag) namely becomes the potassium sulfate end product after the measurement packing.Delivers the chlorine HCl gas by the drawing fan inspiration absorption system, after passes through three step acid pickling cooling, again in turn passes through two levels to fall the membrane absorber, three level of absorption chamber absorptions, the HCl gas namely is absorbed finished, the surplus air disperses into in the atmosphere after the rear part air blower.
