Description

Technical Field

[0001] The utility model relates to the field of pipelines, and more specifically, the utility model relates to a self-balancing water storage type condensate recovery device Background Art

[0002] Condensate recovery and discharge devices are widely used in steam-using equipment. Their main function is to recover and discharge the condensate in the steam, improve the steam dryness, and ensure the steam quality. The existing main methods of condensate recovery and discharge are as follows: The drain outlet of the steam-water separator in the steam pipeline is directly connected to the steam trap and then connected to the condensate recovery and storage device

[0003] However, there are certain problems in the above design. Especially in the scenario of unified recovery of condensate from multiple steam equipment with scattered layouts, in this scenario, the conveying distance between the steam trap and the condensate recovery and storage device is long, which is likely to cause too high back pressure of the steam trap, directly resulting in poor condensate discharge, seriously affecting the steam quality, and directly affecting the safe and efficient production of the equipment Summary of the Utility Model

[0004] The utility model overcomes the deficiencies of the prior art and provides a self-balancing water storage type condensate recovery device, hoping to solve the problem of poor condensate discharge existing in the prior art

[0005] To solve the above technical problems, the utility model adopts the following technical solutions

[0006] A self-balancing water storage type condensate recovery device, comprising a steam delivery pipe, a steam trap, a condensate pipe, and a condensate tank

[0007] The steam delivery pipe is connected to the steam trap, and the outlet of the steam trap is connected to the condensate tank through the condensate pipe

[0008] The condensate tank includes an exhaust pipe and a drain pipe, and the exhaust pipe and the drain pipe are arranged on the condensate tank

[0009] The exhaust pipe is communicated with the atmosphere, and a valve is arranged on the drain pipe

[0010] By connecting the condensate pipe to the condensate tank, the condensate discharged from the steam trap is temporarily stored in the condensate tank via the condensate pipe, and the exhaust pipe of the condensate tank is directly communicated with the atmosphere, ensuring that the pressure in the condensate tank is always 0, thereby ensuring that the pressure at the outlet end of the steam trap is always less than the pressure at the inlet end of the steam trap, ensuring the normal operation of the steam trap, the normal discharge of condensate from the steam equipment, and ensuring the steam quality

[0011] A further technical solution is that the condensate tank further includes a liquid level gauge

[0012] The liquid level gauge is installed on the condensate tank. The valve is a solenoid valve, and the liquid level gauge is connected to the solenoid valve.

[0013] Since the condensate tank only stores the condensate temporarily, in order to prevent the condensate tank from being filled up, the excess condensate must be drained after reaching the liquid level.

[0014] A further technical solution is that the steam delivery pipe includes a steam stop valve, and the steam stop valve is installed on the steam delivery pipe;

[0015] The condensate pipe includes a check valve, and the check valve is installed on the condensate pipe.

[0016] A further technical solution is that the steam delivery pipe further includes a steam filter;

[0017] The steam filter is installed on the steam delivery pipe.

[0018] A further technical solution is that the condensate pipe further includes a sight glass and a pressure gauge;

[0019] The sight glass and the pressure gauge are installed on the condensate pipe.

[0020] The pressure gauge can timely measure the pressure condition of the condensate pipe and can timely detect the situation of too high pressure in the condensate pipe. Once it occurs, the fault can be confirmed through the sight glass.

[0021] A further technical solution is that the self-balancing water storage type condensate recovery device further includes a drainage device, and the drainage device includes a return pipe;

[0022] The return pipe is connected to the drain pipe;

[0023] A water pump, a return water stop valve, a return water check valve, and a return water filtering device are arranged on the return pipe, and the water pump, the return water stop valve, the return water check valve, and the return water filtering device are installed on the return pipe.

[0024] The return pipe is responsible for transporting the condensate in the condensate tank to the subsequent usage location.

[0025] A further technical solution is that the self-balancing water storage type condensate recovery device further includes a drainage device, and the drainage device further includes a pressure relief pipe;

[0026] The pressure relief pipe is connected to the drain pipe, and a pressure relief stop valve is arranged on the pressure relief pipe;

[0027] The condensate tank further includes a liquid level gauge, the liquid level gauge is installed on the condensate tank, and the liquid level gauge is connected to the pressure relief stop valve.

[0028] When the liquid level of the condensate tank exceeds the height of the liquid level gauge, the liquid level gauge controls the pressure relief stop valve to open, and discharges the excessive water from the drain pipe to the pressure relief pipe to avoid excessive pressure in the condensate tank.

[0029] Compared with the prior art, the utility model has at least the following beneficial effects: by connecting the condensate pipe to the condensate tank, the condensate discharged from the steam trap is temporarily stored in the condensate tank via the condensate pipe, and the drain pipe of the condensate tank is directly open to the atmosphere, ensuring that the pressure in the condensate tank is always 0. Furthermore, it ensures that the pressure at the outlet end of the steam trap is always less than the pressure at the inlet end of the steam trap, ensuring the normal operation of the steam trap, the normal discharge of condensate from the steam equipment, and ensuring the steam quality. This device realizes the efficient and safe discharge of condensate, and can also realize functions such as remote control recovery of condensate, automatic control, water level storage and liquid level monitoring, water pressure monitoring, and emergency discharge of condensate.

[0032] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0033] A self-balancing water storage type condensate recovery device, see Figure 1 , including a steam delivery pipe 1, a steam trap 2, a condensate pipe 3, a condensate tank 4, and a drainage device 5;

[0034] The steam delivery pipe 1 is connected to the steam trap 2, and the outlet of the steam trap 2 is connected to the condensate tank 4 through the condensate pipe 3;

[0035] The number of the steam delivery pipes 1 can be determined according to the requirements of the steam delivery system.

[0036] The steam delivery pipe 1 includes a steam stop valve 11 and a steam filter 12, and the steam stop valve 11 and the steam filter 12 are installed on the steam delivery pipe 1;

[0037] The condensate pipe 3 includes a check valve 31, a sight glass 32, and a pressure gauge 33, and the check valve 31, the sight glass 32, and the pressure gauge 33 are installed on the condensate pipe 3.

[0038] The condensate tank 4 includes an evacuation pipe 41, a drain pipe 42, and a liquid level gauge 43. The evacuation pipe 41 and the drain pipe 42 are provided on the condensate tank 4;

[0039] The liquid level gauge 43 is installed on the condensate tank 4. The valve is a solenoid valve, and the liquid level gauge 43 is communicated with the solenoid valve.

[0040] The evacuation pipe 41 is communicated with the atmosphere, and a valve is provided on the drain pipe 42.

[0041] The drainage device 5 includes a return water pipe 421 and a pressure relief pipe 51;

[0042] The return water pipe 421 is connected to the drain pipe 42;

[0043] A water pump, a return water stop valve 422, a return water check valve 423, and a return water filtering device 424 are provided on the return water pipe 421, and the water pump, the return water stop valve 422, the return water check valve 423, and the return water filtering device 424 are installed on the return water pipe 421.

[0044] The pressure relief pipe 51 is connected to the drain pipe 42, and a pressure relief stop valve is provided on the pressure relief pipe 51;

[0045] The condensate tank 4 further includes a liquid level gauge 43. The liquid level gauge 43 is installed on the condensate tank 4, and the liquid level gauge 43 is connected to the pressure relief stop valve.

[0046] During use, the steam containing condensate passes through the steam stop valve 11 and the steam delivery pipe 1 to reach the steam trap 2. In this embodiment, the steam stop valve 11 is a Spirax sacro DN25 standard stop valve, and the steam trap 2 is a Spirax sacro FT14-10 float type steam trap 2;

[0047] The condensate is separated in the steam trap 2 and flows from the water outlet of the steam trap 2 to the condensate tank 4. The check valve 31, the sight glass 32, and the pressure gauge 33 are installed on the condensate pipe 3. In this embodiment, the check valve 31 is a Shanghai Hugong Valve H41H DN25 check valve 31, the pressure gauge 33 is a pressure vacuum gauge, and the sight glass 32 is a Spirax sacro SG253 DN25 sight glass 32. The main function of the pressure gauge 33 is to observe the pressure of each pipeline of the condensate recovery and discharge device, and the function of the sight glass 32 is to observe the internal situation of the condensate pipe 3.

[0048] Since the drain pipe 41 of the condensate tank 4 is directly open to the atmosphere, the pressure in the condensate tank 4 is always maintained at 0, thereby ensuring that the pressure at the outlet end of the steam trap 2 is always lower than the pressure at the inlet end of the steam trap 2, and ensuring the normal operation of the steam trap 2.

[0049] When the liquid level sensor in the condensate tank 4 can monitor the water level height in the condensate tank 4, when the liquid level is too high, the solenoid valve of the drain pipe 42 is opened, and the condensate is discharged from the condensate tank 4.

[0050] When the condensate is discharged from the condensate tank 4, it enters the return pipe 421. After the water level reaches a certain height, the return water stop valve 422 is opened, and the water pump is started. The water pump discharges the condensate from the condensate tank 4;

[0051] If the return pipe 421 fails to work, the liquid level gauge 43 in the condensate tank 4 will detect that the water level has not dropped. At this time, the pressure relief water stop valve of the pressure relief pipe 51 is opened to prevent the pressure in the condensate tank 4 from being too high.

More specifically, within the scope of the disclosure of this application, various variations and improvements can be made to the components and / or layout of the subject combination layout. In addition to the variations and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
