Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steam condensate systems, and more specifically, to a high-efficiency steam condensate system. Background Technology
[0002] In existing technologies, to handle steam condensate, the steam condensate from the condensate pipeline network flows into a flash tank, where a flash evaporation process occurs, rapidly separating it into gas and liquid phases. The gas phase is then transported to the flash tank condenser for cooling via a gas phase pipeline at the top of the flash tank, transforming into a liquid phase. The cooled liquid phase then flows back to the flash tank by gravity. However, this method is not only inefficient but also fails to reduce energy consumption during production and does not achieve efficient resource utilization. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This invention involves the flow of steam condensate from the condensate pipeline into a flash condensate tank. The flash condensate tank then flashes the steam condensate, rapidly separating it into gas and liquid phases. The gas phase enters the flash condenser through the flash steam outlet, where it is cooled and converted into a liquid phase. This liquid phase then flows back into the flash condensate tank's inner cavity through the flash steam condensate inlet, ensuring system stability and continuity. Simultaneously, the liquid phase within the flash condensate tank is pumped to the inner cavities of the heavy component buffer tank and the heavy residue buffer tank. Heat recovery is then achieved in these tanks, effectively reducing energy consumption during production and improving the overall system's economy. After heat recovery, the liquid in the heavy component buffer tank and the heavy residue buffer tank flows back to the circulating water station for further condensate recovery. This achieves efficient resource utilization and a closed-loop cycle, ensuring the sustainable development of the entire process.
[0014] 2. In this invention, the steam condensate entering the inner cavity of the condensate flash tank passes through the inner cavity of the filter chamber via the steam inlet pipe. Then, the steam condensate undergoes a first filtration through the filter box, filtering out impurities and collecting them in the inner cavity of the filter box. Next, the steam condensate undergoes a second filtration through the activated carbon box, thus ensuring that the steam condensate entering the inner cavity of the condensate flash tank is free of impurities, thereby preventing scale formation in the inner cavity of the condensate flash tank.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a high-efficiency steam condensate system, including a condensate flash tank 1, a steam inlet pipe 2 fixedly connected to the top of the condensate flash tank 1, a flash steam outlet 5 provided at the top of the condensate flash tank 1, a flash tank condenser 6 fixedly connected to the end of the flash steam outlet 5 away from the condensate flash tank 1, a flash steam condensate inlet 7 fixedly connected to the bottom of the flash tank condenser 6, a pumping device 9 provided at the bottom of the condensate flash tank 1, a heavy component buffer tank 10 and a heavy residue buffer tank 16 provided at the output end of the pumping device 9, and a circulating water station 11 provided at the bottom of both the heavy component buffer tank 10 and the heavy component buffer tank 16.
[0023] The condensate from the steam condensate through the condensate pipeline 8 flows into the flash condensate tank 1. The flash condensate tank 1 then flashes the condensate, rapidly separating it into gas and liquid phases. The gas phase enters the flash condensate condenser 6 through the flash steam outlet 5, where it is cooled and converted into a liquid phase. This liquid phase then flows into the inner cavity of the flash condensate tank 1 along the flash steam condensate inlet 7, ensuring system stability and continuity. Simultaneously, the liquid phase in the inner cavity of the flash condensate tank 1 is dispersed and transported by pumping equipment 9 to the inner cavities of the heavy component buffer tank 10 and the heavy residue buffer tank 16. Heat is then recovered through these tanks, effectively reducing energy consumption during production and improving the overall system's economy. After heat recovery, the liquid in the heavy component buffer tank 10 and the heavy residue buffer tank 16 flows back to the circulating water station 11, completing the condensate recovery process again. This achieves efficient resource utilization and a closed-loop cycle, ensuring the sustainable development of the entire process.
[0024] Among them, the top end of the steam inlet pipe 2 is fixedly connected to the filter chamber 17, the upper part of the filter chamber 17 is slidably connected to the filter box 18, and the lower part of the filter chamber 17 is slidably connected to the activated carbon box 20.
[0025] The steam condensate passing through the inner cavity of the condensate pipe network 8 passes through the inner cavity of the filter chamber 17 and enters the inner cavity of the condensate flash tank 1 through the steam inlet pipe 2. Then, the steam condensate undergoes a first filtration through the filter box 18, filtering out impurities in the steam condensate and collecting them in the inner cavity of the filter box 18. Then, the steam condensate undergoes a second filtration through the activated carbon box 20, thus ensuring that the steam condensate entering the inner cavity of the condensate flash tank 1 is free of impurities, thereby preventing scale formation in the inner cavity of the condensate flash tank 1.
[0026] The condensate flash tank 1 is fixedly connected to a local level gauge port 12 and a remote level gauge port 13 on its right side, and the local level gauge port 12 and the remote level gauge port 13 are in communication with the inner cavity of the condensate flash tank 1.
[0027] The liquid level is recorded by the local liquid level gauge port 12 and the remote liquid level gauge port 13, thereby determining the liquid level inside the condensate flash tank 1.
[0028] Among them, the top of the condensate flash tank 1 is fixedly connected to a spare pipe 3, and the top of the condensate flash tank 1 and the right side of the spare pipe 3 are fixedly connected to a remote pressure gauge port 4.
[0029] The system is kept in reserve via the spare pipe 3, and the pressure of the condensate flash tank 1 is monitored via the remote pressure gauge port 4.
[0030] Among them, the front side of the condensate flash tank 1 is fixedly connected with an inlet 14, and the front side of the condensate flash tank 1 and the left side of the spare pipe 3 are provided with a remote thermometer port 15.
[0031] The inner cavity of the condensate flash tank 1 can be viewed through the manhole 14, and the temperature of the inner cavity of the condensate flash tank 1 can be detected through the remote thermometer port 15.
[0032] The top of the filter chamber 17 is fixedly connected to the condensate pipe network 8, which is in communication with the inner cavity of the filter chamber 17. The filter box 18 is located above the activated carbon box 20.
[0033] The condensate pipe network 8 is connected to the inner cavity of the filter chamber 17, so that the steam condensate in the inner cavity of the condensate pipe network 8 is filtered twice by the filter box 18 and the activated carbon box 20 before entering the interior of the condensate flash tank 1 along the steam inlet pipe 2.
[0034] The filter chamber 17 has sliding grooves on both the front and rear sides of its inner cavity, and the filter box 18 and the activated carbon box 20 are fixedly connected to sliders 19 on both the front and rear sides. The filter box 18 and the activated carbon box 20 are slidably connected in the sliding grooves through the sliders 19.
[0035] Using the sliders 19 on the front and rear sides of the filter box 18 and activated carbon box 20, when a large amount of impurities are collected in the inner cavity of the filter box 18 or when the activated carbon box 20 has been used for a long time, the filter box 18 and activated carbon box 20 can be pulled out to clean the impurities in the inner cavity of the filter box 18 and then replace the activated carbon box 20.
[0036] Among them, the left side of the filter box 18 and the activated carbon box 20 are fixedly connected with handles, and the bottom of the condensate flash tank 1 is fixedly connected with a support base.
[0037] The handles on the left side of the filter box 18 and activated carbon box 20 make it easy for workers to pull the filter box 18 and activated carbon box 20 out of the inner cavity of the filter chamber 17, and then the support base at the bottom of the condensate flash tank 1 facilitates the installation of the condensate flash tank 1.
[0038] The working principle and usage process of this utility model: the steam condensate from the condensate pipeline 8 flows into the condensate flash tank 1, and the impurities in the steam condensate are filtered by the filter box 18 and collected in the inner cavity of the filter box 18. The steam condensate after coarse filtration by the filter box 18 is then filtered a second time by the activated carbon box 20.
[0039] Next, the condensate flash tank 1 flashes the steam condensate, quickly separating it into two phases: gas and liquid. The gas phase enters the flash tank condenser 6 through the flash steam outlet 5, and is then cooled by the flash tank condenser 6, causing the gas phase to be converted into the liquid phase. The liquid phase then flows into the inner cavity of the condensate flash tank 1 along the flash steam condensate inlet 7.
[0040] Meanwhile, the liquid phase inside the flash condenser 1 is dispersed and transported to the inner cavities of the heavy component buffer tank 10 and the heavy residue buffer tank 16 by the pumping equipment 9. Then, heat is recovered through the heavy component buffer tank 10 and the heavy residue buffer tank 16. After heat recovery, the liquid inside the heavy component buffer tank 10 and the heavy residue buffer tank 16 flows back to the circulating water station 11, completing the recovery of the condensate again.
