Description

Technical Field

[0001] The utility model relates to the technical field of condensed water utilization, in particular to a sodium hydroxide heated steam condensed water recovery and flushing device. Background Art

[0002] When sodium hydroxide is configured into a high-concentration solution, it dissolves and causes the solution temperature to rise (the heat released during the hydration process is greater than the heat absorbed during the diffusion process). Therefore, the solubility of sodium hydroxide increases at this time, and more sodium hydroxide is dissolved in the solution. During the transportation process, the solution will gradually cool down, the solubility of sodium hydroxide will decrease, and the amount of sodium hydroxide that can be dissolved will decrease. Therefore, the excess sodium hydroxide that was originally dissolved will precipitate in the form of crystals. In order to ensure the smooth transportation of the sodium hydroxide solution, the applicant sets the sodium hydroxide delivery pipe to a multi-layer structure, and introduces hot steam into the steam-insulated outer pipe of the sodium hydroxide delivery pipe to ensure that the transportation environment temperature of the sodium hydroxide is always at a high value.

[0003] When the steam used for heating and heat preservation is cooled, part of it will remain in the steam state, while the other part will condense into condensed water. This part of the water vapor mixture has high purity. If it is discharged directly, it will cause huge waste. It can be used to flush other equipment. However, different equipment requires different flushing temperatures. Usually, the temperature of condensed water is relatively high, and there may be situations where it cannot be used directly. Therefore, we propose a sodium hydroxide heating steam condensed water recovery and flushing device. Utility Model Content

[0024] See also Figure 1-2 The utility model provides a technical solution: a sodium hydroxide heated steam condensate water recovery and flushing device, comprising a support plate 1, a cold water tank 2 and an insulation box 3, the cold water tank 2 is supported on the surface of the support plate 1, the insulation box 3 is supported above the cold water tank 2 by a support pad 4, and a water inlet pipe 31 is connected to the upper left side of the insulation box 3, the water inlet pipe 31 is connected to the interior of the insulation box 3, so that the hot condensate enters the insulation box 3 through the water inlet pipe 31 and is stored inside.

[0025] A conduit 5 is connected between the upper side of the cold water tank 2 and the upper side of the insulation box 3. When the insulation box 3 is full of condensed water, excess condensed water flows downward from the conduit 5 into the cold water tank 2 for storage. Fins 21 are provided on both side surfaces of the cold water tank 2. The fins 21 are evenly distributed on the surface of the cold water tank 2, so that the condensed water entering the cold water tank 2 is quickly cooled under the heat dissipation and cooling effect of multiple fins 21. In addition, an overflow pipe 22 connected to the interior of the cold water tank 2 is connected to the upper side of the cold water tank 2. The height of the overflow pipe 22 is less than the bottom height of the conduit 5. When the amount of condensed water stored in the cold water tank 2 is too much, it can be discharged from the overflow pipe 22.

[0026] A water pump 7 is installed on the surface of the support plate 1 on the right side of the cold water tank 2 and the insulation box 3, and a vertical pipe 6 is vertically arranged on the side of the water pump 7. The vertical pipe 6 is connected to the inlet of the water pump 7, and a connecting pipe 61 is connected between the vertical pipe 6 and the bottom of the cold water tank 2 and the bottom of the insulation box 3, and an electromagnetic valve 63 is installed on the connecting pipe 61. A water outlet pipe 71 is connected to the outlet of the water pump 7, and the water outlet pipe 71 is connected to the outlet of the water pump 7, so that the water outlet pipe 71 is connected to the water gun. When in use, the upper electromagnetic valve 63 can be opened alone to allow hot condensed water to be pumped into the water gun and sprayed out of the flushing equipment, or the lower electromagnetic valve 63 can be opened alone to allow cool condensed water to be pumped into the water gun and sprayed out of the flushing equipment, and the upper and lower electromagnetic valves 63 can also be opened at the same time to mix the hot condensed water and the cool condensed water to form warm water that is pumped into the water gun and sprayed out of the flushing equipment.

[0027] A cold water pipe 62 is connected to the side of the vertical pipe 6, and a solenoid valve 63 is installed on the cold water pipe 62. When the amount of cool condensed water in the cold water tank 2 is insufficient or the condensed water in the cold water tank 2 is not cooled to a suitable temperature, the cold water pipe 62 can be connected to the cold water supply pipeline to open the solenoid valve 63 to supplement cool water to meet usage needs.

[0028] When in use, the water inlet pipe 31 is connected to the outflow pipe of condensed water, the cold water pipe 62 is connected to the clean water supply pipe, the overflow pipe 22 is connected to the drainage pipe, and the outlet pipe 71 is connected to the water gun. The condensed water will enter the insulation box 3 through the water inlet pipe 31 for insulation storage. Excess condensed water will overflow into the cold water tank 2 below through the conduit 5, and under the action of the fins 21, the condensed water in the cold water tank 2 will be quickly cooled down. If there is a lot of water, it can overflow from the overflow pipe 22. When other chemical equipment needs to be flushed, if hot water flushing is required, the solenoid valve 63 on the connecting pipe 61 between the insulation box 3 and the vertical pipe 6 is opened separately, and the water pump 7 is started to extract the hot condensed water, which is guided from the outlet pipe 71 to the water gun to spray out and use hot water to flush the equipment. When it is necessary to use warm water to flush the equipment, the solenoid valve 63 on the connecting pipe 61 between the vertical pipe 6 and the insulation box 3 and the cold water tank 2 can be opened at the same time. The hot condensed water in the insulation box 3 and the cooled condensed water in the cold water tank 2 are mixed and pumped to the water gun for spraying. When only cold water is needed for flushing, the solenoid valve 63 on the connecting pipe 61 between the vertical pipe 6 and the cold water tank 2 can be opened separately to draw the cooled condensed water into the water gun for spraying to flush the equipment. When the amount of condensed water in the cold water tank 2 is insufficient or the temperature has not dropped to the angle temperature, and warm water needs to be mixed or cold water is used alone for flushing, the solenoid valve 63 below can be closed, and the solenoid valve 63 on the cold water pipe 62 can be opened to directly add cold water to the vertical pipe 6, thereby replacing the cooled condensed water.
