Description

[0002] The molten slag of the yellow phosphorus electric furnace contains a considerable amount of heat. At present, the domestic yellow phosphorus production generally adopts the water quenching process. A slag pool is set at the slag outlet of the yellow phosphorus furnace, and the molten slag flows directly into the slag pool. The water vapor generated after the water quenching water absorbs heat rises and evaporates the water vapor formed by the cold air. The water temperature in the slag pool will be maintained above 60°C, especially in autumn and winter. The evaporation mist formed by the water vapor emitted in the slag pool directly affects the sight distance of the slag grabbing crane operator, making the operation difficult, resulting in the inability to use the slag grabbing crane normally, and even causing the slag grabbing crane to be paralyzed, forcing the yellow phosphorus furnace to stop production. There are major safety hazards and production shutdown hazards at the work site due to too much water mist, so it is necessary to remove the water vapor in the slag pool.
[0003] The current slag pool water vapor removal device mainly relies on a motor-driven negative pressure fan to absorb water vapor. However, when the amount of water vapor in the slag pool is too large, the load on the motor is too large. In addition, during the production process of the yellow phosphorus industry, a large amount of heat energy in the yellow phosphorus tail gas cannot be utilized, resulting in energy waste.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-6 The utility model provides a technical solution: a device for removing water vapor from a slag pool based on the heat of combustion of yellow phosphorus tail gas, comprising a shell 1, a cylinder 2, a connecting pipe 3, a hose 4, a gas collecting hood 5, a partition 6, a heat inlet pipe 7, a turbine 8, a fan blade 9, a connecting rod 10, a spiral tube 11, and a one-way valve 12.
[0025] This device has the effect of adjusting the position of the gas collecting hood, specifically:
[0026] The outer shell 1 is a hollow cylindrical structure, with a cylinder 2 connected to the top of the outer shell 1. The inside of the cylinder 2 is hollow, and a connecting pipe 3 is arranged through the upper surface of the cylinder 2. The connecting pipe 3 is L-shaped, and two connecting pipes 3 are symmetrically arranged. A hose 4 is connected between the two connecting pipes 3, and one end of the connecting pipe 3 on the other side is connected to an air collecting hood 5. A connecting rod 10 is arranged on the outer surface of the air collecting hood 5 to be connected to the outer surface of the cylinder 2, and the connecting rod 10 is a telescopic structure.
[0027] like Figure 1 As shown, the shell 1 is placed on one side of the Huanglin slag pool, and the gas collecting hood 5 is held and pulled to one side so that the gas collecting hood 5 is located above the slag pool. When the gas collecting hood 5 moves, the gas collecting hood 5 drives the connecting pipe 3 on one side to move, and at the same time stretches the connecting rod 10 and the hose 4, so that the connecting rod 10 and the hose 4 are extended, so as to always keep the gas collecting hood 5 connected with the device.
[0028] This device has the effect of removing water vapor by utilizing the heat from the combustion of yellow phosphorus tail gas, specifically:
[0029] A driving structure is provided inside the shell 1. The driving structure is provided with a turbine 8 to utilize the heat generated by the combustion of yellow phosphorus tail gas, so as to achieve the effect of collecting water vapor without using a motor. The driving structure includes a partition 6. The partition 6 is fixedly installed on the inner wall of the shell 1, and two partitions 6 are provided in parallel up and down. The two partitions 6 divide the interior of the shell 1 into three chambers. A heat inlet pipe 7 is provided on the side surface of the shell 1, and the other end of the heat inlet pipe 7 penetrates the surface of the shell 1 and enters the lowermost chamber inside the shell 1. The middle chamber inside the shell 1 contains water. A water inlet with a cover is provided on the side surface of the shell 1 and penetrates the middle chamber of the shell 1. A vent is provided on the surface of the upper partition 6. The inner wall of the upper chamber of the shell 1 is rotatably connected to the turbine 8, and the turbine 8 is aligned with the vent on the surface of the partition 6. The rotating shaft of the turbine 8 penetrates the surface of the shell 1 and the cylinder 2 and is connected to the fan blade 9. The fan blade 9 is located inside the cylinder 2.
[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the heat inlet pipe 7 is connected to the yellow phosphorus tail gas combustion device, so that the heat from the combustion of the yellow phosphorus tail gas enters the interior of the shell 1 through the heat inlet pipe 7, and water is injected into the space between the two partitions 6 through the water inlet provided on the side surface of the shell 1. The heat from the combustion of the yellow phosphorus tail gas is used to heat the water, so that the water evaporates. The steam generated by the evaporation rises from the air vents on the surface of the partition 6, driving the turbine 8 to rotate. The rotation of the turbine 8 drives the upper fan blades 9 to rotate. The rotating fan blades 9 generate negative pressure in the cylinder 2, so that the water vapor in the slag pool is absorbed through the air collecting hood 5.
[0031] This device has the effect of steam condensation and reflux, specifically:
[0032] A condensation structure is arranged on one side of the outer shell 1, and a spiral tube 11 is arranged in the condensation structure to condense water vapor and then reflux it. The condensation structure includes the spiral tube 11, and the spiral tube 11 is a hollow spiral structure. One end of the spiral tube 11 penetrates the surface of the outer shell 1 and enters the upper chamber of the outer shell 1, and the other end of the spiral tube 11 penetrates the surface of the outer shell 1 and enters the middle chamber of the outer shell 1. A one-way valve 12 is arranged inside the spiral tube 11, and the flow direction of the one-way valve 12 is from the spiral tube 11 to the outer shell 1.
[0033] like Figure 3 and Figure 5 As shown, after the steam drives the turbine 8 to rotate, the steam enters from the spiral tube 11 on one side. During the downward movement of the spiral tube 11, the steam is condensed into water by the condensation of the air and flows back to the cavity of the shell 1 along the one-way valve 12 at the end of the spiral tube 11 to evaporate again.
[0034] Working principle: When using the device for removing water vapor from the slag pool based on the heat of yellow phosphorus tail gas combustion, the gas collecting hood 5 can be used to collect water vapor in the slag pool, and the heat generated by the combustion process of yellow phosphorus tail gas drives water to evaporate, so that the water vapor is used to drive the turbine 8 to rotate. The rotation of the turbine 8 drives the fan blades 9 to rotate to generate negative pressure, which drives the gas collecting hood 5 to collect water vapor. The fan blades 9 are driven by the yellow phosphorus tail gas to reduce energy. The connecting pipes 3 are connected by a hose 4, so that the gas collecting hood 5 can be retracted, which is convenient for extending the gas collecting hood 5 above the slag pool to absorb water vapor. After the water vapor drives the turbine 8 to rotate, it is condensed through the spiral tube 11 and can be returned to the outer casing 1 for recycling, thereby increasing the overall practicality.
