Description

Technical Field

[0001] The utility model relates to the technical field of low-pressure steam recovery and utilization, in particular to a low-pressure steam recovery and utilization device. Background Art

[0002] Low-pressure steam refers to steam produced at a lower pressure. In industrial applications, steam is usually produced as gaseous water by heating liquid water above its boiling point. When the steam is produced at a lower pressure, we call it low-pressure steam. The pressure range of this steam is usually below atmospheric pressure (i.e. negative pressure) to medium pressure levels (e.g., a few bars to tens of bars), depending on the application requirements. Low-pressure steam is widely used in many industrial fields. For example, in industries such as food processing, textiles, papermaking, and chemicals, low-pressure steam is often used as an energy source for heating, drying, distillation, or driving equipment. Due to its lower pressure, low-pressure steam is safer, easier to operate, and easier to manage than high-pressure steam.

[0003] At present, more water vapor will be produced in low-pressure steam, and the gas with more water will be discharged into the air, which will cause the humidity in the discharge area to be higher. At the same time, low-pressure steam has a certain amount of heat. These low-pressure steams discharged into the air will also cause the humidity in the discharge area to be higher, which will have a certain impact on the environment of the discharge area. Therefore, a low-pressure steam recovery and utilization device is proposed. Utility Model Content

A rectangular drainage port is provided inside the drainage seat 8, and the flow limiting seat 7 is installed at an inclined angle and has the same inclination angle as the steam collecting plate 6. The outer walls on the opposite side of the two flow limiting seats 7 are at the same distance from the outer walls on the opposite side of the two drainage seats 8.

[0026] A cooling assembly is provided on the outer wall of the recovery box 1, and the cooling assembly includes a mounting plate 13 fixedly mounted on the right outer wall of the recovery box 1, a water pump 14 is fixedly mounted on the top of the mounting plate 13, a water inlet pipe 15 and a water input pipe 16 are fixedly mounted on the water inlet end and the water outlet end of the water pump 14, respectively, a water outlet pipe 17 is fixedly mounted on the left outer wall of the cold water tank 12, a second valve 18 is sleeved on the outer peripheral wall of the water outlet pipe 17, the input pipe 16 passes through the right side wall of the recovery box 1 and is fixedly mounted on the right side wall of the cold water tank 12, the water outlet pipe 17 passes through the left side wall of the recovery box 1 and extends to the outside, and both the input pipe 16 and the water outlet pipe 17 are connected to the interior of the cold water tank 12.

[0027] In this embodiment, the front and rear outer walls and the left and right outer walls of the steam collecting plate 6 are fitted with the front and rear inner walls and the left and right inner walls of the recovery box 1 .

[0028] In this embodiment, when low-pressure steam encounters the heat conducting plate 10, heat exchange will occur, and the heat in the steam will be transferred to the heat conducting plate 10, causing the steam temperature to decrease and then condense into water. Due to the heat exchange, the heat in the steam is effectively transferred and released, and at the same time the steam is converted into liquid water.

[0031] The working principle of the above embodiment is:

[0032] First, the steam is input into the interior of the recovery box 1 through the steam inlet pipe 2. At this time, most of the low-pressure steam will contact the steam collecting plate 6 and part of the water vapor will adhere to its outer wall. At this time, the water vapor will gather into water droplets and drip into the interior of the recovery box 1. Then the gas will flow upward through the vents and contact the heat conduction plate 10 and the first guide seat 11. At this time, after being affected by the cold water tank 12, the low-pressure steam will quickly condense into water and drip on the top of the steam collecting plate 6. The collected water will be limited by the flow limiting seat 7 and then discharged into the bottom inner wall of the recovery box 1 through the drain seat 8. Finally, the cooled gas will be discharged through the exhaust pipe 3.
