Description

Technical Field

[0001] The utility model relates to the technical field of brine nitration, in particular to a brine nitration preheating device. Background Art

[0002] Brine refers to highly mineralized water, which is often used to extract certain chemical raw materials, such as salt, iodine, boron, bromine, etc. Zigong, Sichuan, China has been famous for its abundant brine since ancient times. Brine or salt brine is classified according to its burial location. There are two types of shallow brine and deep brine. The brine minerals in the Sichuan region represented by Zigong belong to deep brine. Deep brine is generally located deep in the stratum and is a highly mineralized groundwater. This type of brine is buried deep and is highly closed. Its formation is mainly determined by paleogeology, paleoclimate and paleohydrogeology. Therefore, deep brine is often accompanied by oil, gas and rock salt deposits.

[0003] When the brine evaporates, the water content gradually decreases, and the salt substances in the brine gradually reach a saturated state. As the evaporation continues, some of the salt substances begin to crystallize, commonly known as evaporation crystallization. Since the boiling point of water in the brine is approximately equal to 100°C, a longer heating time is required during evaporation crystallization, and more heat and operating costs are consumed. Therefore, a brine preheating device for nitrate precipitation is proposed to solve the above-mentioned problems. Utility Model Content

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] In the embodiment, Figure 1-2 A preheating device for saltpeter separation of brine is provided, comprising a support 1, an insulated box 2 is arranged on the support 1, a transport pipe 3 for transporting brine is arranged in the insulated box 2, and the two ends of the transport pipe 3 respectively penetrate the two side surfaces of the insulated box 2, a water storage tank 4 is arranged on the support 1, a heating component 5 for outputting heat to the insulated box 2 is arranged in the water storage tank 4, a condensed water reflux component 6 is arranged in the insulated box 2, and the condensed water reflux component 6 is connected to the water storage tank 4, and the brine enters the insulated box 2 through one end of the transport pipe 3 and flows in the transport pipe 3. At the same time, the heating component 5 in the water storage tank 4 starts to work, generates heat and transfers the heat to the insulated box 2. The heat in the insulated box 2 causes the brine to gradually heat up during transportation, thereby achieving a preheating effect.

[0019] Reference Figure 1-2 , wherein a plurality of support plates 7 are fixedly installed in the insulated box 2, and the support plates 7 are located outside the transport pipe 3;

[0020] Through the above-mentioned structural setting, the support plate 7 is used to fix and support the transport pipe 3 to ensure that it maintains a stable position and shape in the insulation box 2. Since the transport pipe 3 needs to pass through the two side surfaces of the insulation box 2, if there is no support from the support plate 7, the transport pipe 3 may be deformed or displaced due to its own weight or the force generated by the flow of brine, affecting the preheating effect.

[0021] Reference Figure 1-2, wherein the transport pipe 3 includes a plurality of arc-shaped joints and a plurality of connecting pipes, wherein the plurality of connecting pipes and the plurality of connecting pipes are arranged in a rectangular array and are all located on the same horizontal plane, the plurality of arc-shaped joints and the plurality of connecting pipes are arranged in a staggered distribution, the two openings of the arc-shaped joints are connected to the ends of the adjacent connecting pipes, and the plurality of arc-shaped joints and the plurality of connecting pipes are combined together to form a curved serpentine spring distribution;

[0022] Through the above-mentioned structural setting and the unique design of the transport pipe 3, the brine can flow in the heat preservation box 2 along a longer path and at a slower flow rate, thereby absorbing heat more fully and achieving efficient preheating. This working principle ensures that the brine can reach the ideal preheating temperature before entering the evaporation crystallization equipment, providing favorable conditions for subsequent processing.

[0023] Reference Figure 1-2 , wherein the heating assembly 5 includes an electric heating wire 51, which is arranged in the water storage tank 4, a water inlet 52 is arranged on one side surface of the water storage tank 4, a three-way pipe 53 is connected to the top of the water storage tank 4, and the other two ends of the three-way pipe 53 are connected to an air inlet pipe 54 which has one end penetrating and extending into the heat preservation box 2, and the two air inlet pipes 54 are respectively located on both sides of the heat preservation box 2;

[0024] Through the above-mentioned structural setting, the electric heating wire 51 is set in the water storage tank 4. When powered on, the electric heating wire 51 will generate heat, thereby heating the water in the water storage tank 4, and further generate water vapor. The water vapor entering the insulation box 2 will mix with the air in the insulation box 2 to form convection, thereby increasing the temperature in the insulation box 2, and can disperse heat more evenly, making the temperature distribution in the insulation box 2 more uniform, thereby improving the preheating effect of the brine.

[0025] Reference Figure 1-2 , wherein the condensed water reflux assembly 6 comprises a collecting hole 61, the inner cavity bottom wall of the heat preservation box 2 is provided with a collecting hole 61, one end of the collecting hole 61 is connected with a U-shaped liquid sealing tube 62, and the end of the U-shaped liquid sealing tube 62 away from the collecting hole 61 is connected with the water storage tank 4;

[0026] Through the above-mentioned structural setting, the brine will evaporate and condense due to heat, and condense water will be produced on the bottom wall of the inner cavity of the insulation box 2. The condensed water enters the collecting hole 61 and flows into the U-shaped liquid seal tube 62, which can not only guide the condensed water from the collecting hole 61 to the water storage tank 4 for reuse, but also prevent the water or other liquids in the water storage tank 4 from flowing back to the insulation box 2, thereby effectively preventing the reverse flow of gas.

[0027] Reference Figure 1-2, wherein a cover plate 8 is hingedly connected to the top of the insulated box 2 by a hinge, and an overload protection device 9 is provided on the cover plate 8, and the overload protection device 9 includes a corrugated hose 91, and the corrugated hose 91 is connected to the cover plate 8, a blower 92 is provided on one side of the bracket 1, and the suction end of the blower 92 is connected to the corrugated hose 91, and a temperature sensor 93 is provided on the cover plate 8;

[0028] Through the above-mentioned structural arrangement, when the temperature sensor 93 detects that the temperature inside the insulation box 2 is too high, the linkage mechanism between the corrugated hose 91 and the blower 92 will be immediately started, and the hot air in the insulation box 2 will be sucked in through the corrugated hose 91. Due to the strong suction action of the blower 92, the hot air in the insulation box 2 is quickly drawn out, thereby reducing the internal temperature and preventing the occurrence of overload or overheating.
