For this reason, the applicant proposes a yellow phosphorus slag high-temperature water quenching waste heat recovery device. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] In the processing of yellow phosphorus, the high-temperature yellow phosphorus slag needs to be water quenched, and the waste heat of water vapor in the water quenching process needs to be recovered and utilized. Therefore, a yellow phosphorus slag high-temperature water quenching waste heat recovery device is needed. In the actual use of most traditional yellow phosphorus slag high-temperature water quenching waste heat recovery devices, part of the heat cannot be well absorbed by the device during the circulation of water vapor inside the device, resulting in the loss of waste heat of water vapor, which reduces the practicality of the device and also reduces the waste heat recovery rate of water vapor. For this reason, the applicant proposes a yellow phosphorus slag high-temperature water quenching waste heat recovery device.

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a yellow phosphorus slag high temperature water quenching waste heat recovery and utilization device, comprising a yellow phosphorus slag high temperature water quenching box 1, the exhaust end of the yellow phosphorus slag high temperature water quenching box 1 is connected to a heat absorbing mechanism 2 by a pipeline, the heat absorbing mechanism 2 comprises a waste heat recovery box 201, a plurality of groups of fixed plates 202 are fixed to the inner wall of the waste heat recovery box 201, a steam exhaust hole 203 is opened at the top of one end of the fixed plate 202, and a heat insulation plate 202 is fixed between each group of adjacent fixed plates 202. 04, a heat absorbing pipe 205 is fixed at the center of the top of the inner wall of the waste heat recovery box 201, and the drainage end of the heat absorbing pipe 205 passes through the top of several groups of fixed plates 202 and several insulation plates 204, and then a shelf pipe 206 is fixed. Several groups of copper blocks 207 are fixed to the outer wall of the heat absorbing pipe 205, and the several groups of copper blocks 207 are respectively located inside the several groups of fixed plates 202. A water storage tank 208 is fixed to the top of the outer wall of the waste heat recovery box 201, and a water storage tank 208 is fixed to the top of the outer wall of the water storage tank 208. The motor 209, the output end of the motor 209 passes through the top of the outer wall of the water storage tank 208 and is fixed with a stirring rod 210, the outer wall of the heat absorption mechanism 2 is fixed with a stabilizing mechanism 3, the yellow phosphorus slag high temperature water quenching box 1, the heat absorption mechanism 2 and the stabilizing mechanism 3 are connected in sequence, the two sides of the outer wall of the water storage tank 208 are respectively fixed with water inlet pipes 211, the drainage end of the shelving pipe 206 passes through the bottom of the inner wall of the waste heat recovery box 201 and is fixed with a drainage valve 212, and one side of the top of the outer wall of the waste heat recovery box 201 is fixed An exhaust pipe 213 is fixed, a steam inlet pipe 214 is fixed to the bottom of one side of the outer wall of the waste heat recovery box 201, adjacent exhaust holes 203 are respectively located at the opposite ends of adjacent fixed plates 202, the cross-section of the insulation plate 204 is equal to the difference between the area of ​​the fixed plate 202 and the area of ​​the exhaust holes 203, the stirring end of the stirring rod 210 is located inside the heat absorption tube 205, the yellow phosphorus slag high-temperature water quenching box 1, the motor 209 and the drain valve 212 are electrically connected in sequence, and the three share a control terminal.

[0023] It should be noted that: when the device is in use, first, the water vapor inside the yellow phosphorus slag high-temperature water quenching box 1 will enter the steam inlet pipe 214 through the pipeline, and enter the bottom of the inner wall of the waste heat recovery box 201 through the steam inlet pipe 214. As the water vapor continues to enter, the water vapor will pass through several groups of fixed plates 202 in turn and be discharged from the exhaust pipe 213. In this process, water will enter from the water inlet pipe 211. At the same time, the motor 209 will also drive the stirring rod 210 to rotate. When the water flows into the heat absorption tube 205, it will be turned by the stirring rod 210 to make the water flow fully contact with the inner wall of the heat absorption tube 205. At this time, the heat of the water vapor inside the waste heat recovery box 201 will be absorbed by the heat absorption tube 205 and the copper block 207 until it is absorbed by the water flow. When the water flow just enters, the water vapor on the top is absorbed by the water flow at the bottom in the process of continuous flow. In addition, under the action of the insulation plate 204, the temperature transfer between each group of fixed plates 202 can be blocked. Therefore, the temperature of the top water vapor will become lower. At this time, the temperature of the flowing water is greater than the temperature of the top water vapor. At this time, the water flow can absorb the residual heat of the top water vapor very well. Because the steam inlet pipe 214 of the device is at the bottom of one side of the outer wall of the waste heat recovery box 201, at this time, the water flow at the bottom will fully absorb the heat of the water vapor and make the temperature of the water flow equal to the temperature of the water vapor. Subsequently, the absorbed water flow will accumulate in the shelf pipe 206. With the control of the drain valve 212, the water flow in the shelf pipe 206 is discharged into the water storage tank 301 for storage. A drain valve can be opened on the other side of the waste heat recovery box 201 to prevent water from accumulating in several groups of fixed plates 202 during long-term use of the device, thereby affecting the use of the device.

[0024] like Figure 4 As shown, the utility model provides a technical solution: a yellow phosphorus slag high-temperature water quenching waste heat recovery device, including a stabilizing mechanism 3, the stabilizing mechanism 3 includes a water storage tank 301, fixed frames 302 are respectively fixed on both sides of the outer wall of the water storage tank 301, a stabilizing plate 303 is commonly fixed to the bottom of the water storage tank 301 and the two fixed frames 302, stabilizing frames 304 are respectively fixed to the tops of the two ends of the stabilizing plate 303, a fixing frame 305 is commonly fixed to the opposite surfaces of the two stabilizing frames 304, and a support seat 306 is fixed to the bottom of the stabilizing plate 303.

[0025] It should be noted that: during the use of the device, the two stabilizing frames 304 and the fixing frame 305 can make the heat absorption mechanism 2 more stable, and the inner wall of the water storage tank 301 can be provided with a heat-insulating material to prevent the temperature of the water from being lost.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
