Description

Technical Field

[0001] This utility model relates to the technical field of pressure boosting devices, and in particular to a high-temperature condensate pressure boosting device. Background Technology

[0002] In industrial production, after steam completes its heat exchange, it releases a large amount of latent heat and transforms into high-temperature condensate. This high-temperature condensate typically reaches temperatures above 100°C, and in some processes even exceeds 180°C, containing abundant thermal energy. If this high-temperature condensate can be effectively recycled and reused, and then fed back into the boiler system as makeup water, it can not only reduce boiler fuel consumption and lower energy procurement costs, but also significantly improve energy efficiency.

[0003] Currently, among existing high-temperature condensate pressurization equipment, such as the patent with authorization announcement number CN221505706U, this utility model relates to the technical field of pressurization devices, and in particular to a high-temperature condensate pressurization device. It activates the pressurization component to increase the pressure inside the storage tank, and then opens the drainage component. The high-temperature condensate at the bottom of the storage tank is discharged into the heat-using equipment under the pressure inside the storage tank, thereby improving the secondary utilization of high-temperature condensate.

[0004] However, it was found during the use of the device that its filtration effect on condensate was poor, which increased the likelihood of dirt in the condensate contaminating the equipment and increased maintenance costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-temperature condensate pressurization device that reduces the contamination of the tank by dirt in the condensate, lowers the personnel cleaning and maintenance costs, and improves the ease of use.

[0006] This utility model discloses a high-temperature condensate pressurization device, comprising a tank and a drain valve, the drain valve being connected to the outer wall of the tank; it also includes a detection device, a pressurization component, a delivery box, an inlet pipe, and a first shut-off valve. The delivery box is installed on the upper part of the outer wall of the tank, the inlet pipe is connected to the upper part of the outer wall of the delivery box, the first shut-off valve is connected between the bottom of the delivery box and the top of the tank, a first filter screen is installed on the inner wall of the delivery box, and a detection device is provided at the bottom of the first shut-off valve. The detection device is used to detect the liquid level in the tank and to seal the gap between the tank and the delivery box. The pressurization component is connected to the tank and is used to pressurize the tank. The system is pressurized internally; high-temperature condensate is transported to the delivery box through the inlet pipe. The condensate entering the delivery box is filtered through the first filter screen, and the filtered condensate is then transported to the tank for storage, thereby reducing the contamination of the tank by dirt in the condensate and lowering personnel cleaning and maintenance costs. The liquid level in the tank is detected by a detection device. When the condensate in the tank reaches the set height, the detection device seals the gap between the tank and the delivery box and controls the first shut-off valve to close. Then, the pressurization component increases the pressure in the tank to the set pressure. By opening the drain valve, the pressurized condensate is discharged for reuse, improving the ease of use of the device.

[0007] Preferably, the detection device includes a control device, a cylinder, a ring, a support rod, a float, and a sealing plate. The top of the cylinder is connected to a first shut-off valve. The ring is installed on the inner wall of the cylinder. The support rod is slidably installed on the lower part of the cylinder. A float is provided at the bottom of the support rod. The top of the support rod is connected to the bottom of the sealing plate. The sealing plate matches the ring. A control device is provided on the cylinder to control the first shut-off valve to close. The first shut-off valve delivers condensate from the delivery box to the cylinder. The condensate is discharged into the tank through the bottom of the cylinder. When the water level in the tank rises, the water level causes the float to rise. The float then moves the sealing plate upward, thereby causing the sealing plate and the ring to cooperate in sealing the cylinder. At the same time, the control device is triggered to close the first shut-off valve, thereby improving the convenience of automatic sealing when the water level in the tank reaches the set height.

[0008] Preferably, the pressurization assembly includes a pump body, an air pipe, and a second shut-off valve. The pump body is connected to the tank via the air pipe, and the second shut-off valve is connected to the air pipe. The pump body pressurizes the tank via the air pipe, and the second shut-off valve improves the convenience of maintaining pressure in the tank by closing it.

[0009] Preferably, the control device includes a push switch and a controller. The push switch is located on the outer wall of the cylinder, and the controller is located on the outer wall of the conveying box. After the support rod moves upward, it presses the push switch. The push switch controls the first shut-off valve to close through the controller, thereby improving the convenience of automatic control of the first shut-off valve to close.

[0010] Preferably, it also includes an air intake hood and a second filter screen. The air intake hood is connected to the input end of the pump body, and the second filter screen is installed inside the air intake hood. The pump body draws in outdoor air through the air intake hood and filters the air through the second filter screen to reduce the amount of dirt in the air entering the tank.

[0011] Preferably, it also includes a safety valve, which is connected and installed on the tank body; by installing a safety valve, the safety of pressure control inside the tank is improved.

[0012] Preferably, the top of the conveyor box is provided with an inspection port; this improves the convenience of cleaning and maintaining the first filter screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: High-temperature condensate is transported to the conveying box through the water inlet pipe. The condensate entering the conveying box is filtered through the first filter screen. The filtered condensate is then transported to the tank for storage, thereby reducing the contamination of the tank by dirt in the condensate and reducing personnel cleaning and maintenance costs. The liquid level in the tank is detected by a detection device. When the condensate in the tank reaches the set height, the detection device seals the tank and the conveying box and controls the first shut-off valve to close. Then, the pressure in the tank is increased to the set pressure by the pressurization component. By opening the drain valve, the pressurized condensate is discharged for reuse, improving the ease of use of the device. Attached Figure Description

[0022] like Figure 4 As shown, the detection device includes a control device, a cylinder 7, a ring 8, a support rod 9, a float 10, and a sealing plate 11.

[0023] In this embodiment, high-temperature condensate is transported to the conveying tank 3 through the inlet pipe 4. The condensate entering the conveying tank 3 is filtered through the first filter screen 6. The filtered condensate is then transported to the tank 1 for storage, thereby reducing the contamination of the tank 1 by dirt in the condensate and reducing personnel cleaning and maintenance costs. The liquid level in the tank 1 is detected by a detection device. When the condensate in the tank 1 reaches the set height, the detection device seals the tank 1 and the conveying tank 3 and controls the first shut-off valve 5 to close. Then, the pressure in the tank 1 is increased to the set pressure by the pressurization component. By opening the drain valve 2, the pressurized condensate is discharged for reuse, improving the ease of use of the device. Example 2

[0024] Based on Example 1, such as Figure 3 As shown, this utility model discloses a high-temperature condensate pressurization device.

At the same time, the control device is triggered to close the first shut-off valve 5, thereby improving the convenience of automatic sealing after the water level in the tank 1 reaches the set height.
