Description

Technical Field

[0001] The utility model relates to the technical field of sodium sulfide production, in particular to a methyl halide separation and clarification device for sodium sulfide production. Background Art

[0002] The production process of sodium sulfide mainly includes several major production processes such as waste thenardite material, batching process, roasting process, thermal process, evaporation and tableting, and packaging.

[0003] During the thermal process, the ash cake car is pulled to the thermal tower by a winch. During the transportation, the crude alkali ash cake will naturally cool down and form a crust; the ash cake is lifted to the top of the feed port of the thermal tank (the thermal tank is inside the thermal tower) by a hoist, and then slowly enters the thermal tank after being continuously crushed by the thermal tower's built-in crusher. At the same time, the recycled secondary brine is added for thermalization. Stirring is always turned on during the entire thermal process. The sodium sulfide solution (concentrated alkaline water) after complete thermalization is pumped into the transfer tank, filtered and pressed by the transfer tank's built-in mechanical filter, and then enters the primary brine tank for standby use. Solid waste washing mud residue S1 is generated during the mechanical filtration process.

[0004] When brine A is concentrated and the temperature is too low, the reducing substances cannot be adsorbed and will soon precipitate, causing the volume of the cylinder to become smaller until it cannot be used normally, thereby shortening the service life of the clarification cylinder, which is not conducive to its promotion and use.

[0005] Therefore, how to provide a methyl halide separation and clarification device for sodium sulfide production with a heating function has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by the utility model is how to provide a methyl halide separation and clarification device for sodium sulfide production with a heating function.

[0007] To achieve the above-mentioned purpose, the utility model provides a methyl halide separation and clarification device for sodium sulfide production, comprising: a clarification cylinder body, the clarification cylinder body is provided with a feed inlet for methyl halide liquid to be treated, and the clarification cylinder body is provided with a discharge port for the methyl halide liquid after clarification, the clarification cylinder body is provided with a heating mechanism, the heating mechanism is a heating disc groove, and the heating disc groove is fully surrounded and installed outside the clarification cylinder body, forming a heating function for the clarification cylinder body.

[0008] The clarification tank body adopts the existing structure in the market in this field, and is used for the clarification and separation process of the methyl brine. The feed inlet and the discharge port form a material channel for the methyl brine to enter and exit the clarification tank body. The heating function of the heating mechanism on the clarification tank body accelerates the separation and clarification of the methyl brine after being heated by the heating disc groove, which not only improves the separation and clarification effect, but also avoids blockage inside the clarification tank body, thereby increasing the service life of the clarification tank body.

[0009] Preferably, the clarification tank body is a cylindrical structure with a size of 5 meters*3.5 meters and is made of stainless steel.

[0010] The clarification tank body made of stainless steel has the characteristics of strong corrosion resistance, long service life, environmental protection, high temperature resistance, high pressure resistance, smooth surface and excellent texture.

[0011] Preferably, the heating plate grooves are arranged in six parallel longitudinal directions and are made of channel steel.

[0012] The heating plate slot has the following advantages:

[0013] Uniform heating: The heating plate slot is made with a special process, which can overcome the disadvantage that ordinary electric heating plates are easily damaged due to long-term continuous work. By selecting isostatically pressed high-purity graphite with excellent thermal conductivity as the heating body, the temperature uniformity of each point on the heating panel is guaranteed.

[0014] Precise temperature control: PID parameter self-checking can automatically adjust the heating rate to achieve a temperature control accuracy of ±0.1°C and a single-point temperature fluctuation of ±2.0°C, ensuring the accuracy of temperature control.

[0015] Energy saving and high efficiency: By adopting a unique heating and heat preservation method, it saves more than 20% energy compared with similar products and improves energy utilization efficiency.

[0016] Anti-corrosion design: The surface of graphite thermal conductive material is not afraid of strong acid and alkali corrosion, the connecting parts are made of anti-corrosion materials, and the chassis is treated with anti-corrosion spraying to resist harsh corrosive environments. The chassis holes are coated with high-temperature anti-corrosion materials to enhance the durability of the equipment.

[0017] Split design: The main chassis and controller are split, and the control part is placed outside the window through a data cable, which avoids corrosion of electronic components and facilitates the maintenance of the equipment.

[0018] Preferably, water inlets and water outlets are symmetrically installed on both sides of the heating plate groove, and the installation height of the water inlet is lower than the installation height of the water outlet.

[0019] With this design, the hot water inside the heating plate groove forms a low-in and high-out structure, and the temperature of the hot water is 110°.

[0020] Preferably, the feed inlet is a brine liquid inlet pipe, which is installed on the top of the clarification tank body, and the center point of the water outlet end of the brine liquid inlet pipe corresponds to the center point of the clarification tank body.

[0021] The other end of the brine inlet pipe is connected to an external chemical pump, so that the methane brine is transferred into the clarification tank body through the pump under the action of the brine inlet pipe, and a buffer pipe is preset inside the clarification tank body to reduce the flow of the methane brine.

[0022] Preferably, the material outlet is a material transfer pipe, which is installed on one side of the clarification cylinder body, and a valve is preset on the clarification cylinder body.

[0023] The installation height of the liquid transfer pipe is higher than the installation height of the lower hopper, and the separated clarified water is transferred into the external crystallization tank through the liquid transfer pipe for subsequent processing steps.

[0024] Preferably, the discharge port is a lower hopper, which is installed at the bottom of the clarification cylinder body and has a conical structure with specifications of 3.5 meters * 0.18 * 2 meters, and a sewage valve is installed on the lower hopper.

[0025] The clarified material accumulates inside the lower hopper and is discharged to the outside through the drain valve. The conical structure of the lower hopper has a strong arch-breaking ability and can effectively aid flow, ensuring that the material can flow smoothly and avoid blockage, thereby further reflecting the practicality of this device.

[0026] Preferably, the overflow pipe is installed on one side of the clarification tank body, above the water inlet.

[0027] Enter from the top to the bottom and then add evenly upwards. If the water level is too high, it will flow back to the designated position through the overflow pipe.

[0028] The beneficial effects of the utility model are:

[0029] When the utility model is in use, the heating function of the heating mechanism on the clarification cylinder body accelerates the separation and clarification of the methyl halide liquid after being heated by the heating disc groove, which not only improves the separation and clarification effect, but also avoids blockage inside the clarification cylinder body, thereby increasing the service life of the clarification cylinder body, and is conducive to promotion and use.
