Description

Technical Field

[0001] This utility model relates to the field of condenser extraction systems, and more specifically, to a cooling device for a condenser extraction system. Background Technology

[0002] The condenser extraction system, also known as the vacuum system, is a crucial component of a condensing steam turbine unit. Its primary function is to establish and maintain low back pressure in the turbine unit and a vacuum state in the condenser to ensure the turbine's normal operation. This system continuously extracts non-condensable gases that leak into the turbine and condenser through various pathways, preventing their accumulation in the condenser and thus maintaining the condenser's vacuum level. The condenser extraction system typically consists of a water ring vacuum pump and a steam-water separator, among other equipment. The extracted non-condensable gases are treated before being released into the atmosphere.

[0003] The existing condenser extraction system faces a significant challenge in summer: when using cooling tower circulating water as makeup water, the temperature of the circulating water rises due to increased ambient temperature, and this hot water, when added to the ejector pool, causes a simultaneous increase in the pool's water temperature. This temperature rise leads to a decrease in water density, which in turn affects the density of the water column inside the ejector. The reduced water column density weakens the ejector's extraction capacity, ultimately lowering the turbine's vacuum and impacting the unit's overall operating efficiency and performance.

[0004] Therefore, we have made improvements to this by proposing a cooling device for a condenser extraction system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cooling device for a condenser extraction system, which solves the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A cooling device for the condenser extraction system is provided to solve the above problems.

[0008] The application is as follows:

[0009] The device includes a water jet air ejector, a connecting pipe installed on one side of the water jet air ejector, and a T-pipe fixedly connected to the middle of the connecting pipe. A valve is fixedly installed on the upper surface of one side of the T-pipe, and a water supply pipe is provided at one side interface of the T-pipe. One end of the water supply pipe extends into the water tank, and a connecting mechanism is provided between the water supply pipe and the T-pipe.

[0010] As a preferred technical solution of this application, the connection mechanism includes a fixing head and an installation head. The fixing head is fixedly installed on one side surface of the tee pipe, and the installation head is fixedly installed on one end surface of the water supply pipe. The installation head and the fixing head are connected by a snap-fit ​​connection, and the water supply pipe and the tee pipe form a snap-fit ​​structure.

[0011] As a preferred technical solution of this application, the inner wall of the fixing head is provided with sliding grooves on both sides, and the sliding grooves are slidably connected with locking blocks, and the lower end of the locking blocks is inclined. The outer surface of the mounting head is provided with a locking groove, and the inner surface of the locking groove is inclined. The lower end of the locking block is locked and connected to the locking groove.

[0012] As a preferred technical solution of this application, the inside of the slide is rotatably connected with a threaded rod, and the threaded rod is connected to the locking block by a threaded connection. A knob is fixedly installed on the other end surface of the threaded rod.

[0013] As a preferred technical solution of this application, a sealing ring is fixedly installed inside the fixing head, and a sealing groove is opened on one side surface of the mounting head, and the sealing ring and the sealing groove are connected by a snap-fit ​​connection.

[0014] As a preferred technical solution of this application, a sealing ring is bonded to the inside of the sealing groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By introducing low-temperature makeup water from the water tank, this device can replenish the water jet pool in a timely and flexible manner, effectively balancing and reducing the water temperature of the water jet pool that rises due to increased ambient temperature. This function directly solves the problem of reduced water density and weakened pumping capacity of the water jet caused by rising water temperature, thereby ensuring the stability of the turbine vacuum value. By maintaining a suitable density of the water column inside the water jet, this device can maintain the optimal pumping state of the water jet and avoid a decrease in pumping capacity due to rising water temperature. This not only improves the overall efficiency of the condenser pumping system, but also significantly enhances the unit's operating performance and thermal economy.

[0018] 2. The use of a connecting mechanism, employing a snap-fit ​​connection and threaded rod tightening, ensures a secure connection between the water supply pipe and the tee pipe. Simultaneously, the multi-seal design (including sealing rings and sealing collars) effectively prevents leakage during the water supply process, reducing installation difficulty and facilitating subsequent maintenance and inspection, thus ensuring clean water quality and minimizing energy loss.

[0031] Combination Figure 1 - Figure 4 As shown, the present invention provides a cooling device for a condenser extraction system, including a water jet ejector 1, a connecting pipe 2 installed on one side of the water jet ejector 1, and a three-way pipe 3 fixedly connected to the middle of the connecting pipe 2. A valve 4 is fixedly installed on the upper surface of one side of the pipe of the three-way pipe 3, and a water supply pipe 5 is provided at one side interface of the three-way pipe 3. One end of the water supply pipe 5 extends into a water tank, and a connecting mechanism 6 is provided between the water supply pipe 5 and the three-way pipe 3.

[0032] In this embodiment, the core component of the device is the water jet ejector 1. A connecting pipe 2 is cleverly installed on one side of the ejector 1, and a tee pipe 3 is securely connected to the middle of the connecting pipe 2. A valve 4 is fixedly installed above one side of the tee pipe 3 to control the water flow. Crucially, the other port of the tee pipe 3 is connected to a water supply pipe 5, which extends directly into the water tank to provide low-temperature water to the ejector tank. This solves the problem of reduced water density and weakened ejector pumping capacity caused by rising water temperature, thus ensuring the stability of the turbine vacuum value.

[0033] As a preferred embodiment, based on the above method, the connecting mechanism 6 further includes a fixing head 601 and an mounting head 602. The fixing head 601 is fixedly installed on one side surface of the tee pipe 3, and the mounting head 602 is fixedly installed on one end surface of the water supply pipe 5. The mounting head 602 and the fixing head 601 are connected by a snap-fit ​​connection, and the water supply pipe 5 and the tee pipe 3 form a snap-fit ​​structure.

[0034] In this embodiment, the connecting mechanism 6 consists of two parts: a fixing head 601 and an mounting head 602. The fixing head 601 is firmly installed on one side surface of the tee pipe 3, while the mounting head 602 is fixedly connected to one end surface of the water supply pipe 5. The two parts are connected by a snap-fit ​​connection, which allows the water supply pipe 5 to be easily and securely connected to the tee pipe 3, forming a tight and reliable snap-fit ​​structure, which facilitates installation when needed.

The lower end of the locking blocks 604 is designed to be inclined. Matching this, the outer surface of the mounting head 602 is formed with an inclined slot 605. When the mounting head 602 approaches the fixing head 601, the lower end of the locking blocks 604 will automatically slide along the inclined inner surface of the slot 605 and finally lock into it. It can also squeeze the mounting head 602 to form a firm and stable connection. The installation process is simple and the connection efficiency is improved.

[0038] In this embodiment, a rotatable threaded rod 606 is added inside the slide groove 603, and the threaded rod 606 is threadedly connected to the locking block 604. By rotating the knob 607 at the other end of the threaded rod 606, the locking block 604 can be easily driven to move within the slide groove 603, thereby achieving the fastening or release between the mounting head 602 and the fixing head 601.
