Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of condensate recovery, specifically a condensate recovery tank for chemical production. Background Technology
[0002] A condensate recovery tank is a device capable of recycling condensate generated in industrial or commercial processes. It effectively recovers water resources, preventing waste and reducing environmental pollution. Condensate recovery is used to recover condensate generated in various steam-water heat exchangers or production processes. Condensate is high-quality water containing a significant amount of heat energy, making its recovery in steam heating systems a crucial energy and water conservation measure. Currently, most condensate recovery tanks utilize gas heat exchange, but the cooling effect of gas on condensate is relatively poor, leading to incomplete liquefaction. Therefore, we provide a condensate recovery tank for chemical production to address these issues. Utility Model Content
[0003] To address the aforementioned problems, specifically those raised in the background section, this utility model proposes a chemical production condensate recovery tank, comprising a tank body, a heat exchange box disposed above the tank body, and a serpentine channel forming the inner cavity of the heat exchange box. An input pipe is connected to one end of the heat exchange box within the serpentine channel, and an output pipe is connected to the other end. The output pipe extends through the top of the tank body. A circulation pipe is disposed within the serpentine channel, with both ends of the circulation pipe extending outwards from the side wall of the heat exchange box and connected to a water tank at both ends. A pump body and a chiller are sequentially disposed on the input end of the circulation pipe. A drain valve is connected to the bottom of the side wall of the tank body, and a pressure regulating valve is connected to the top of the side wall of the tank body.
[0004] Preferably, the side wall of the tank is provided with an insertion port, a filter plate is inserted into the insertion port, and slides adapted to the filter plate are fixedly provided on both sides of the inner cavity of the tank. The filter plate is fixed to the tank with bolts.
[0005] Preferably, a liquid level sensor is embedded in the side wall of the tank below the filter plate.
[0006] Preferably, a water injection pipe is connected to the top of the water tank, and an observation window is provided on the side wall of the water tank.
[0007] Preferably, the heat exchange box is a split structure including a top shell and a bottom shell, which are fixed together by bolts, and the serpentine channel is located between the top shell and the bottom shell.
[0008] The beneficial technical effects of this utility model are as follows: This condensate recovery tank is equipped with a heat exchange box, and a serpentine channel is opened in the heat exchange box. The coolant in the internal circulation pipe circulates, so that the gaseous water in the serpentine channel can release heat and liquefy, and enter the inner cavity of the tank along with the gas. The liquid water remains in the pipe under its own gravity, while the gas can be discharged through the pressure regulating valve. This condensate recovery method can efficiently liquefy the gaseous water through the circulation of coolant in the circulation pipe, avoiding the problem of incomplete liquefaction of gaseous water.
[0009] By opening a port on the side wall of the pipe, the filter plate can be easily disassembled and installed, making it easier to clean or replace the filter plate. At the same time, by setting a slide that matches the filter plate in the inner cavity of the tank, the stability of the filter plate in the inner cavity of the tank is ensured, thereby enabling better filtration of condensate.

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0015] This utility model proposes a condensate recovery tank for chemical production, including a tank body 1. A port 14 is provided on the side wall of the tank body 1, and a filter plate is inserted into the port 14. Slides 41 adapted to the filter plates are fixedly provided on both sides of the inner cavity of the tank body 1. The filter plates are fixed to the tank body 1 with bolts. The port 14 on the side wall of the tank body facilitates the disassembly and assembly of the filter plates, thus facilitating cleaning or replacement. A heat exchange box 2 is provided above the tank body 1. The inner cavity of the heat exchange box 2 has a serpentine channel 21. The heat exchange box 2 is a split structure including a top shell and a bottom shell, which are fixed together with bolts. The serpentine channel 21 is located between the top shell and the bottom shell of the heat exchange box 2. This design facilitates the processing of the serpentine channel 21, and the top shell and bottom shell are sealed. An input pipe 22 is connected to one end of the serpentine channel 21, and an output pipe 23 is connected to the other end. The output pipe 23 passes through the top of the tank body 1. The input pipe 22 is used to connect to... The gaseous water is discharged into the inner cavity of the tank 1 at the output end. A circulation pipe 3 is installed in the serpentine channel 21. Both ends of the circulation pipe 3 extend outward from the side wall of the heat exchange box 2, and both ends of the circulation pipe 3 are connected to a water tank 31. A water injection pipe 311 is connected to the top of the water tank 31, and an observation window is provided on the side wall of the water tank 31. A pump body 32 and a chiller 33 are sequentially installed on the input pipe of the circulation pipe 3. The serpentine channel 21 is opened in the heat exchange box 2. By utilizing the circulation of the low-temperature coolant in the circulation pipe 3, the gaseous water in the serpentine channel 21 can release heat and liquefy, and enter the inner cavity of the tank 1 together with the gas. The liquid water remains in the pipe under its own gravity. A drain valve 11 is connected to the bottom of the side wall of the tank 1, and a pressure regulating valve 12 is connected to the top of the side wall of the tank 1. A liquid level sensor 13 is embedded in the side wall of the tank 1 below the filter plate. The liquid level sensor 13 can monitor the condensate water level in the inner cavity of the tank 1.

The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.
[0017] Working principle: When recovering condensate, the condensate pipeline to be recovered can be connected to the input pipe 22. At the same time, an appropriate amount of coolant is injected into the water tank 31 through the water injection pipe 311, and the pump body 32 and the refrigeration unit 33 are started. The pump body 32 can drive the coolant in the water tank 31 to circulate in the circulation pipe 3, and the refrigerant can reduce the temperature of the coolant. When the gaseous water flows in the serpentine channel 21, it can exchange heat with the coolant in the circulation pipe 3, thereby liquefying the gaseous water. The liquefied condensate and gas both enter the inner cavity of the tank 1. The condensate can fall to the top of the filter plate 4 by its own gravity, and fall to the bottom of the inner cavity of the tank 1 through the filtration of the filter plate 4. The gas can be discharged at the pressure regulating valve 12. When the liquid level sensor 13 detects the condensate water level in the inner cavity of the tank 1, the drain valve 11 can be opened to discharge and collect the condensate.
