Description

Technical Field

[0001] This utility model relates to the field of condensate recycling technology in papermaking, and in particular to a condensate recycling device. Background Technology

[0002] The traditional paper industry has always been a major water user and generates a large amount of wastewater, resulting in high annual costs for wastewater treatment for paper manufacturers.

[0003] The evaporation stage of pulp production produces a large amount of steam, which contains many pollutants and cannot be directly discharged. The processing plant needs to condense the steam to form condensate, which is then treated as wastewater. In traditional condensate recycling devices, when steam is condensed, it condenses into water droplets through the condenser tube and then drips naturally. During this process, the water droplets coat the outer surface of the condenser tube, preventing subsequent steam from making better contact with the condenser tube, resulting in a significant reduction in condensation efficiency.

Detailed Implementation

[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 4As shown, this utility model discloses a condensate recycling device, comprising a condensate tank 4, a cooling mechanism, and a water droplet sweeping mechanism 7. The cooling mechanism is installed inside the condensate tank 4, and the water droplet sweeping mechanism 7 is connected to the cooling mechanism. A steam inlet is provided at the bottom of the condensate tank 4, and a steam outlet 2 is provided at the top of the condensate tank 4.

[0028] The cooling mechanism includes several sets of condensing components 9 and a cooling circulation component. Several sets of condensing components 9 are arranged from bottom to top inside the condensing box 4. All condensing components 9 are connected to the cooling circulation component. The water droplet sweeping mechanism 7 is connected to the condensing components 9.

[0029] The water droplet sweeping mechanism 7 includes several wiper blades 701, connectors 703, and linear drive components 704. One of the wiper blades 701 is sleeved on the outside of a condensation component 9 and is movably connected to the condensation component 9. The wiper blades 701 are connected to each other through the connectors 703, and the linear drive component 704 is driven to connect with the connectors 703.

[0030] The working principle of this utility model is as follows: In actual production and use, when it is necessary to condense the steam in the papermaking process, the steam can be introduced into the condenser box 4 through the steam inlet, so that the steam passes through several sets of condenser components 9 one by one from bottom to top. The cooling circulation component continuously replenishes the condenser components 9 with cold water in a circulating manner. When the steam comes into contact with the surface of the condenser component 9, heat exchange occurs, thereby condensing the water vapor in the steam into water droplets. When it is necessary to accelerate the falling of water droplets on the condenser component 9, the linear drive component 704 can be operated, so that the linear drive component 704 drives the scraper 701 through the connector 703 to continuously scrape off the water on the outer surface of the condenser component 9, so that the water droplets can fall into the lower part of the condenser box 4 for collection.

[0031] Furthermore, the condensation assembly 9 includes an inlet pipe 904, an outlet pipe 901, two flow dividers 903, and several condenser pipes 902. A flow divider 903 is respectively arranged on both sides of the interior of the condensation chamber 4. One side of one flow divider 903 is connected to the other side of the other flow divider 903 via several condenser pipes 902. A flow channel is provided inside the flow divider 903, and the interior of each condenser pipe 902 communicates with the flow channel. The inlet pipe 904 is provided on the other side of one flow divider 903, and the outlet pipe 901 is provided on the other side of the other flow divider 903. Both the inlet pipe 904 and the outlet pipe 901 are connected to the cooling circulation assembly. Several scraper holes 702 are provided on the scraper blade 701, and one scraper hole 702 passes through the outside of one condenser pipe 902. The scraper blade 701 is movably connected to the outer surface of the condenser pipe 902.

[0032] As can be seen from the above description, when better condensation of the steam passing through the condenser tube 902 is required, the cooling circulation component can be operated, so that the cooling circulation component continuously introduces cooling water into the condenser tube 902 through the water inlet pipe 904. When the steam comes into contact with the condenser tube 902, heat exchange occurs between the steam and the cooling water inside the condenser tube 902, thereby condensing the water in the steam into water droplets. After the cooling water has exchanged heat, the hotter cooling water flows back into the cooling circulation component through the water outlet pipe 901 for further cooling, and the cooled water is then replenished into the condenser tube 902.

[0033] Furthermore, the cooling circulation assembly includes a cooling water circulation tank 1, an inlet pipe 3, and an outlet pipe 8. The cooling water circulation tank 1 has an outlet on one side and an inlet on the other side. One side of the outlet pipe 8 is connected to the outlet, and the inlet pipes 904 are all connected to the other side of the outlet pipe 8. One side of the inlet pipe 3 is connected to the inlet, and the outlet pipes 901 are all connected to the other side of the inlet pipe 3.

[0034] As can be seen from the above description, when it is necessary to continuously cool the cooling water in the condenser tube 902, the cooling water circulation tank 1 can be operated to cool the cooling water to a suitable temperature, and then introduced into the condenser tube 902 through the outlet pipe 8. When it is necessary to cool the cooling water in the condenser tube 902 again, the cooling water in the condenser tube 902 can be introduced into the cooling water circulation tank 1 through the inlet pipe 3 for further cooling.

[0035] Furthermore, it also includes a steam extraction assembly, which is provided on the steam inlet. The steam extraction assembly includes a steam extraction pump and a steam outlet pipe 11. The steam outlet pipe 11 is vertically arranged inside the steam inlet. The upper part of the steam outlet pipe 11 is arranged inside the condenser box 4, and the lower part of the steam outlet pipe 11 is connected to the steam extraction pump.

[0036] Furthermore, it also includes a steam dispersion component 12, which is disposed above the steam outlet pipe 11. The steam dispersion component 12 is connected to the inner surface of the condenser box 4, and the lower part of the steam dispersion component 12 is configured as an arc shape.

[0037] As can be seen from the above description, when it is necessary to better disperse the water entering the condenser 4, the steam pump can be operated to draw the steam that needs to be condensed into the condenser 4 through the steam inlet pipe. Then, the steam discharged from the steam inlet pipe collides with the arc-shaped lower surface of the steam disperser 12, causing the steam to be dispersed, thereby enabling the condenser pipe 902 to better condense the dispersed steam.

[0038] Furthermore, it also includes a drain outlet 10, which is provided at the lower part of the condenser box 4.

[0039] As can be seen from the above description, the condensate that falls into the lower part of the condensation box 4 can be discharged through the drain outlet 10.

[0040] Furthermore, it also includes support feet 5, and several support feet 5 are fixedly connected to the bottom of the condenser box 4.

[0041] As can be seen from the above description, it is beneficial for the device to operate more stably.

[0042] Furthermore, it also includes a PLC controller, which is electrically connected to both the cooling mechanism and the water droplet sweeping mechanism 7.

[0043] As can be seen from the above description, it is beneficial to adjust the parameters of the condensate recycling device through the PLC controller, and makes it more convenient for operators to operate the condensate recycling device. Example 1
