[0003] 1. Not conducive to environmental protection and energy saving
When using the Mannheim method reactor to produce potassium sulfate, the actual reaction temperature of potassium chloride and concentrated sulfuric acid is about 530 degrees, and considering that the concentrated sulfuric acid and the hydrogen chloride gas produced by the reaction are highly corrosive, leading to the traditional The Mannheim method reaction furnace uses refractory brick material as the main material of the furnace body. Although the refractory brick material has good corrosion resistance and high temperature resistance, its heat conduction efficiency is very low. Therefore, in order to ensure the temperature in the reaction furnace To maintain it at about 530 degrees, it needs to use an external temperature of about 1000 degrees, which will cause a lot of energy loss in the middle, and the heat transfer area on the top of the traditional Mannheim method reactor is small, the heat utilization rate is low, and heat energy is wasted; Heim method reactor is not conducive...

Abstract

The invention provides a potassium sulphate reaction furnace. The potassium sulphate reaction furnace comprises a reaction furnace body, an outer furnace body surrounding the reaction furnace body and a flame path arranged between the reaction furnace body and the outer furnace body. A concentrated sulfuric acid inlet and a potassium chloride inlet are formed in the upper portion of the reaction furnace body, and the reaction furnace body is made of nickel chrome. A chlorine hydride gas discharging opening is formed in the upper portion of the reaction furnace body. Four overhauling observing openings are formed in the lateral sides of the reaction furnace body, each lateral side of the reaction furnace body is correspondingly provided with one overhauling observing opening, and the overhauling observing openings are communicated with the outer furnace body. According to the potassium sulphate reaction furnace, the materials of the furnace body are improved to achieve the energy-saving aim and the environment-friendly aim.

Example Embodiment

[0024] See figure 1 , The present invention proposes a potassium sulfate reaction furnace, including a reaction furnace 1, an outer furnace body 2 surrounding the periphery of the reaction furnace, and a fire channel 3 arranged between the reaction furnace and the outer furnace body; the selection of materials for the reaction furnace 1 Existing nickel-chromium alloys; can also choose to include nickel 20%-30% by mass, 20%-30% chromium, and the rest are rare earth nickel-chromium alloys. The best choice is a nickel-chromium alloy with a mass ratio of 20%-30% nickel, 25%-30% chromium, and the rest is rare earth.
[0025] The top of the reactor 1 is provided with a feed port, and there are two feed ports, namely the concentrated sulfuric acid feed port 4 and the potassium chloride feed port 5; the top of the reactor 1 is also provided with a hydrogen chloride gas discharge port 6, which reacts The lower part of the furnace 1 is provided with two potassium sulfate outlets 7; the outer furnace body 2 adopts a three-layer structure, the inner and outer layers are made of high alumina bricks, the outer layer is made of refractory bricks, and the middle layer is filled with insulating materials 8, such as perlite. The reaction furnace 1 is formed by splicing a plurality of nickel-chromium alloy plates, which is convenient and quick to install and combine.
[0026] The side of the reaction furnace 1 can be provided with 4 inspection observation ports 9, and one side of the reaction furnace 1 is provided with an inspection observation port 9, which is connected to the outer furnace body 2. The number of inspection observation ports 9 can be set as required In the present invention, four are used, and the four inspection and observation ports 9 are symmetrically arranged on the four sides of the reactor. When equipment fails, the cause can be easily found.
[0027] The reaction furnace 1 may be provided with a stirring device. The stirring device includes a rotating shaft 10 and blades 11 provided on the rotating shaft 10. The rotating shaft 10 is controlled to rotate by a motor and a reducer to perform a raw material mixing reaction.
[0028] The lower part of the reaction furnace 1 is provided with a support frame 12, and the entire furnace body is supported by the support frame 12 and the platform 13. There are preferably four support frames 12, which can effectively support the furnace body. The lower end of the reaction furnace 1 is in a position that is directly opposite to the axis of rotation. An alloy protective sleeve 14 is provided, and the alloy protective sleeve 14 is connected to the platform 13.
