[0002] At present, a large amount of high-temperature water in the high-temperature slag pool during the production of yellow phosphorus in a yellow phosphorus factory cannot be directly used as the jacket heat preservation water because it contains phosphorus slag. Even if the high-temperature water in the high-temperature slag pool is filtered by a filtering device, it still cannot be used as the jacket heat preservation water because the filtered high-temperature water will inevitably contain fine powder substances, and these fine powder substances are prone to precipitation and cause blockage in the jacket.

[0003] Therefore, in the prior art, clear water heated separately is usually introduced into the heat preservation jacket of the high-temperature slag pool to insulate the high-temperature slag pool. However, this method requires an additional heating device to heat the water for the heat preservation jacket, resulting in high costs and high energy consumption. Summary of the Utility Model

[0012] Preferably, one side wall of the hot water storage tank is attached to the outer side wall of the high-temperature slag pool, and the part of the outer side wall of the high-temperature slag pool attached to the hot water storage tank is not wrapped with the heat preservation jacket.

[0013] Preferably, an automatic water replenishing device is arranged in the hot water storage tank.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a heat preservation system for a high-temperature slag pool in yellow phosphorus production to solve the problems existing in the above-mentioned prior art and reduce the heat preservation cost of the high-temperature slag pool in yellow phosphorus production.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] As Figures 1 to 2 shown, this embodiment provides a heat preservation system 100 for a high-temperature slag pool in yellow phosphorus production, including:

[0031] The heating pipeline 3 is arranged in the high-temperature slag pool 1;

[0032] The hot water storage tank 2 is arranged outside the high-temperature slag pool 1, and the water outlet of the heating pipeline 3 is communicated with the hot water storage tank 2;

[0033] The heat preservation unit, the heat preservation unit includes three heat preservation jackets 8; all the heat preservation jackets 8 are connected in series; each heat preservation jacket 8 is sleeved on the equipment to be heat-preserved, and the heat preservation jacket 8 is used to heat-preserve the equipment to be heat-preserved;

[0034] The hot water pump 6, the water pumping port of the hot water pump 6 is communicated with the water outlet of the hot water storage tank 2 through the water pumping pipe 5, the water outlet of the hot water pump 6 is communicated with the water inlet of the heat preservation unit through the water supply pipe 7, and the water outlet of the heat preservation unit is communicated with the water inlet of the heating pipeline 3 through the water return pipe 4.

[0035] In the heat preservation system 100 of the high-temperature slag pool in the yellow phosphorus production of this embodiment, the heating pipeline 3 arranged in the high-temperature slag pool 1 can use the high-temperature water in the high-temperature slag pool 1 to heat the water in the heat preservation jacket 8. Under the pumping action of the hot water pump 6, the water in the heat preservation jacket 8 circulates continuously in the heat preservation jacket 8, the heating pipeline 3 and the hot water storage tank 2. When the water in the heat preservation jacket 8 passes through the heating pipeline 3, it is heated by the high-temperature water in the high-temperature slag pool 1, so that the water in the heat preservation jacket 8 is maintained at a relatively high temperature. It not only does not require an additional heating device to heat the water in the heat preservation jacket 8, reducing the heat preservation cost, but also can ensure that the water in the heat preservation jacket 8 is maintained at a relatively high temperature, improving the heat preservation effect of the high-temperature slag pool 1.

[0036] In the optional scheme of this embodiment, preferably, the heating pipeline 3 is spirally distributed in the high-temperature slag pool 1 and the heating pipeline 3 is closely attached to the inner wall of the high-temperature slag pool 1. The spiral distribution of the heating pipeline 3 makes the heating pipeline 3 have a longer length, extending the retention time of the water in the heat preservation jacket 8 in the heating pipeline 3, that is, increasing the heating time of the water in the heat preservation jacket 8 by the high-temperature water in the high-temperature slag pool 1, thereby improving the heating effect and temperature of the water in the heat preservation jacket 8. Making the heating pipeline 3 closely attached to the inner wall of the high-temperature slag pool 1 minimizes the impact of the heating pipeline 3 on the processes in the high-temperature slag pool 1.

[0037] In the optional scheme of this embodiment, preferably, one side wall of the hot water storage tank 2 is attached to the outer side wall of the high-temperature slag pool 1, and the part of the outer side wall of the high-temperature slag pool 1 attached to the hot water storage tank 2 is not wrapped with the heat preservation jacket 8. Since one side wall of the hot water storage tank 2 is attached to the outer side wall of the high-temperature slag pool 1, and the outer side wall of the high-temperature slag pool 1 has a relatively high temperature due to the high-temperature water inside, the outer side wall of the high-temperature slag pool 1 can heat and insulate the hot water storage tank 2, making full use of the heat energy of the high-temperature slag pool 1.

[0038] In this embodiment, the hot water storage tank 2 is annular and the hot water storage tank 2 is sleeved outside the high-temperature slag pool 1.

[0039] In an alternative embodiment of the present embodiment, preferably, an automatic water replenishing device (not shown in the figure) is provided in the hot water storage tank 2. The automatic water replenishing device includes a water replenishing pipe and a float travel switch. One end of the water replenishing pipe extends into the hot water storage tank 2 and the other end is communicated with a water source. The float travel switch is used to control the opening and closing of the end of the water replenishing pipe extending into the hot water storage tank 2. The automatic water replenishing device in the hot water storage tank 2 can automatically replenish water to the hot water storage tank 2 to ensure the water volume for the heat preservation jacket 8. Specifically, when the liquid level in the hot water storage tank 2 is lower than the set value, the float travel switch controls the opening of the end of the water replenishing pipe extending into the hot water storage tank 2, so that the water in the water source enters the hot water storage tank 2 through the water replenishing pipe. It should be additionally noted that the water source is preferably a faucet.

[0040] In an alternative embodiment of the present embodiment, preferably, a sewage outlet is further provided at the bottom of the hot water storage tank 2. The sewage outlet at the bottom of the hot water storage tank 2 can discharge the polluted water for the heat preservation jacket 8 when the water for the heat preservation jacket 8 is polluted, which is convenient to use. The specific operation during sewage discharge is as follows: First, close the water outlet of the hot water storage tank 2, disconnect the connection between the water pumping port of the hot water pump 6 and the water outlet of the hot water storage tank 2, and turn off the hot water pump 6. Then, install a water extraction pump at the water outlet of the heating pipeline 3, and then open the sewage outlet. The stored water in the heating pipeline 3 and the heat preservation jacket 8 is pumped out into the hot water storage tank 2 through the water extraction pump and discharged through the sewage outlet. After the discharge is completed, remove the water extraction pump, close the sewage outlet, open the water outlet of the hot water storage tank 2, reconnect the water pumping port of the hot water pump 6 and the water outlet of the hot water storage tank 2, and then add clean water to the hot water storage tank 2 as the water for the heat preservation jacket 8.

[0041] In an alternative embodiment of the present embodiment, preferably, the water outlet of the heating pipeline 3 is located at the top of the hot water storage tank 2, so that the pressure at the water outlet of the heating pipeline 3 is relatively low, ensuring the normal water discharge at the water outlet of the heating pipeline 3.

[0042] In an alternative embodiment of the present embodiment, preferably, the water outlet of the hot water storage tank 2 is located at the bottom of the hot water storage tank 2.

[0043] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0044] In the present utility model, specific examples are used to illustrate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
