Description

A kind of potassium sulfate Reaktionsofen
Technical field
The present invention is a kind of production unit of potassium sulfate, particularly a kind of potassium sulfate Reaktionsofen.
Background technology
What traditional potassium sulfate production equipment mainly adopted is Mannheim proeess Reaktionsofen, double-layer furnace body structure inside and outside this Reaktionsofen is built into by refractory brick, and internal layer Reaktionsofen adopts silicon carbide brick to be built into, and forms quirk between interior external furnace body.During production, Repone K and the vitriol oil are added in Reaktionsofen and stir by the Repone K arranged by Reaktionsofen top and vitriol oil entrance, in quirk, produce the high-temperature flue gas of about 1000 degree simultaneously, mainly through silicon carbide vault to Reaktionsofen internal heat transfer, keep reaction in furnace temperature in 530-560 degree left and right, reaction generates potassium sulfate, and the hydrogen chloride gas of generation is discharged by bottom.There is following shortcoming in the structure of this kind of Mannheim proeess Reaktionsofen:
1, environmental protection and energy saving are unfavorable for.When utilizing Mannheim proeess Reaktionsofen to produce potassium sulfate, the temperature of reaction of Repone K and vitriol oil reality is about 530 degree, and consider the vitriol oil and react the hydrogen chloride gas produced all have very high severe corrosive, traditional Mannheim proeess Reaktionsofen is caused to adopt refractory brick material as the main raw of body of heater, although refractory brick material has good erosion resistance and high thermal resistance, but its heat conduction efficiency is very low, therefore in order to ensure that the temperature in Reaktionsofen maintains about 530 degree, need the outer temperature of stove with about 1000 degree, very large energy waste can be caused in centre, and traditional Mannheim proeess Reaktionsofen tip heat transfer area is little, heat utilization efficiency is low, waste heat energy, therefore this Mannheim proeess Reaktionsofen is unfavorable for environmental protection and energy saving.
2, Reaktionsofen base plate is perishable, produces and leaks sour phenomenon.Heat conduction portion due to traditional Mannheim proeess Reaktionsofen mainly concentrates on the silicon carbide vault of Reaktionsofen, and the hydrogen chloride gas that therefore Reaktionsofen produces can only be discharged bottom furnace wall, is therefore easy to corrosion reaction furnace bottom, thus produces the sour phenomenon of leakage.
3, Measuring error inconvenience.Traditional Mannheim proeess Reaktionsofen is owing to adopting firebrick structure, because it is by the brick one-tenth of one piece one piece, be not easy to out more access hole, access hole can only be offered in two of a Reaktionsofen side, can only observe two of a body of heater face and keep in repair, therefore Measuring error be very inconvenient; In addition, traditional Mannheim proeess Reaktionsofen heat radiation is slow, promotes temperature slow, causes the repair time long.
Summary of the invention
The present invention, in order to solve the above-mentioned technical problem existed in background technology, provides a kind of new potassium sulfate Reaktionsofen, transforms the material of body of heater, to reach the object of energy-conserving and environment-protective.
Technical solution of the present invention is: a kind of potassium sulfate Reaktionsofen, comprises Reaktionsofen, is looped around the outer body of heater of Reaktionsofen periphery and is arranged on the quirk between Reaktionsofen and outer body of heater; Be provided with vitriol oil feeding mouth and Repone K feeding mouth above Reaktionsofen, it is characterized in that: the material of described Reaktionsofen is nichrome; Described hydrogen chloride gas discharge outlet is arranged on above Reaktionsofen; The side of described Reaktionsofen is provided with 4 maintenance portholes, and described Reaktionsofen side correspondence arranges a maintenance porthole, and described maintenance porthole is communicated with outer body of heater.
Above-mentioned outer body of heater adopts three-decker, and internal layer is high alumina brick, and skin is refractory brick, middle layer fill insulant material.
Above-mentioned nichrome comprises quality than nickel 20% ?30%, chromium 20% ?30%, and all the other are rare earth.
Above-mentioned nichrome comprises quality than nickel 25% ?30%, chromium 25% ?30%, and all the other are rare earth.
Above-mentioned Reaktionsofen two bottom sides is provided with potassium sulfate outlet.
Above-mentioned lagging material is perlite.
Above-mentioned Reaktionsofen inside is provided with whipping appts, and described whipping appts comprises rotating shaft and is located at the blade in rotating shaft, and described rotating shaft is controlled by motor and step-down gear.
Above-mentioned Reaktionsofen is by multiple nichrome board material splice composition.
The bottom of above-mentioned Reaktionsofen arranges bracing frame, is supported by bracing frame and platform, and bracing frame is 4.
The just right orientation of the lower end of above-mentioned Reaktionsofen and rotating shaft arranges alloy protecting cover, and alloy protecting cover is connected with platform.
The present invention has the following advantages:
1, energy-conserving and environment-protective.Application of the present invention artificially solves potassium sulfate reacting furnace-e/or material should be high temperature resistant, corrosion-resistant and the high problem of thermal conductivity, by a large amount of experiments, practice and demonstration repeatedly, finally select nichrome as the material of Reaktionsofen, meet high temperature resistant, corrosion-resistant and the high requirement of thermal conductivity, the temperature in quirk is made only to need to reach temperature required in body of heater, because of the heat transfer of W-response stove entirety, independent body Reaktionsofen is outward quirk entirely, quirk periphery have employed refractory materials insulation, top light-weight mullite furred ceiling, reach the object of energy-conserving and environment-protective.
2, Reaktionsofen base originally can not corrode, and furnace bottom have employed integral construction, can not produce Lou sour phenomenon.After Reaktionsofen material of the present invention adopts nichrome, the heating region of quirk is comprehensive 360 degree of heat transfers, and therefore hydrogen chloride gas discharge outlet of the present invention can be arranged on above Reaktionsofen, and hydrogen chloride gas can be discharged above body of heater, absorbed completely by absorption tower, can not atmospheric pollution be caused.
3, good in economic efficiency.Reaktionsofen internal diameter of the present invention 6.5 meters, increases and feeds intake, and output is large, good in economic efficiency.
4, maintenance is convenient.After Reaktionsofen material of the present invention adopts nichrome, four maintenance portholes can be set on reacting furnace-e/or side, and be connected with outer body of heater, can overhaul to pinpoint the problems more accurately sooner multiple faces of body of heater, overhaul in time; Minor issue in easy processing production process, also serves the multinomial economic benefits such as cooling is fast, quick heating, maintenance convenience, shortens twice, brought very large energy-conservation usefulness to enterprise than the former production line repair time.
4, good heat-insulation effect.Outer body of heater of the present invention adopts three-decker, and internal layer is high alumina brick, outer refractory brick, middle layer fill insulant material, and general employing fills perlite, and heat insulating is good.
