Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of expansion tanks, in particular to a high-efficiency condensation drain expansion tank. Background Art
[0002] The drain expansion tank is an instrument for separating steam and drain. The drain expansion tank expands and reduces the pressure of the drain in the pressure drain pipeline, separates steam and drain, and introduces the steam into the heat exchanger or deaerator to make full use of its thermal energy, while the drain is introduced into the drain tank and regularly sent to the water supply system.
[0003] The fundamental reason why ordinary hydrophobic expansion tanks have high noise and high working pressure is that the steam temperature in the hydrophobic expansion tank is high. The higher the temperature, the larger the steam volume produced after the separation of the same mass of hydrophobic steam and water. The larger the steam volume, the higher the pressure in the expansion tank, and the greater the flow rate at the exhaust port. The higher the flow rate, the greater the noise, which seriously affects the working environment at the job site. Therefore, it is necessary to improve the existing device to meet actual needs.

[0008] Preferably, a steam exhaust pipe is installed through the top end of the expander body, and a water drain pipe is installed through the bottom end of the expander body.
[0009] Through the above technical solution, a large amount of high-temperature water vapor and hydrophobicity enter the cavity of the expander body, steam and water separation occurs in the cavity, steam is discharged from the upper exhaust pipe, and water is discharged from the lower drain port.
[0010] Preferably, four groups of hydrophobic inlets are provided.
[0011] Through the above technical solution, by providing four groups of drain inlets, the drain can enter uniformly on the circumference, so that the steam in the drain can uniformly contact the guide plate, thereby improving the working efficiency of the expander body.
[0012] Preferably, two groups of guide plates are provided, and the two groups of guide plates are inclined.
[0013] Through the above technical solution, by setting the guide plate, the path of the drain flow is extended, thereby further improving the heat release. Because the guide plate is set at an angle, the condensed water drips to the lower part of the expansion tank body due to its own weight and can then be discharged through the drain pipe.
[0014] Preferably, the cooling pipe is filled with cooling liquid for circulation.
[0015] Through the above technical solution, the coolant in the cooling pipe exchanges heat with the steam to realize the condensation of the steam into water, thereby achieving the purpose of cooling.

[0017] Through the above technical solution, the setting of the micro-perforated plate silencer further plays a role in eliminating airflow noise and meets the low-noise working requirements.
[0018] Compared with the prior art, the utility model provides a high-efficiency condensation drain expansion container, which has the following beneficial effects:
[0019] 1. The utility model transports the drain in the pressure pipeline into the expansion tank body through the drain inlet to expand the capacity and reduce the pressure, separates the drain and steam, and discharges the drain to the outside through the drain pipe. The separated steam rises and is discharged in sequence through the guide plate, blades, micro-perforated plate muffler and exhaust pipe. During the discharge of high-temperature steam, cooling water is input into the cold water pipe, and the cooling water sprays water mist into the inside of the expansion tank body through the nozzle. The cooling water contacts the high-temperature steam, thereby achieving the purpose of preliminary cooling of the high-temperature steam.
[0020] 2. The utility model extends the path of drain flow by setting a guide plate, thereby further improving the release of heat. Because the guide plate is inclined, the coolant in the cooling pipe exchanges heat with the steam to realize the condensation of steam into water. The condensed water drips to the lower part of the expansion tank body due to its own weight, and then can be discharged through the drain pipe, thereby achieving the purpose of secondary cooling. At the same time, the motor is started, the motor drives the shaft to rotate, the rotation of the shaft drives the blades to rotate, the rotation of the blades can disperse the steam, reduce the exhaust steam volume flow, and greatly reduce the working pressure of the expansion tank body.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-3 A high-efficiency condensation hydrophobic expansion tank comprises an expansion tank body 1, a hydrophobic inlet 2 is installed through the lower outer wall of the expansion tank body 1, a cold water pipe 3 is installed inside the expansion tank body 1, a nozzle 4 is installed on the outer wall of the cold water pipe 3, a guide plate 5 is installed inside the expansion tank body 1, a cooling pipe 6 is installed in an annular manner inside the guide plate 5, a motor 7 is fixedly installed on the upper side end of the expansion tank body 1, a rotating shaft 8 is fixedly installed on the output shaft of the motor 7, and blades 9 are installed in a circular array on the outer wall of the rotating shaft 8.
[0027] Specifically, a steam exhaust pipe 10 is installed through the top of the expander body 1, and a drain pipe 11 is installed through the bottom of the expander body 1. The advantage is that a large amount of high-temperature water vapor and hydrophobicity enter the cavity of the expander body 1, and steam-water separation occurs in the cavity. The steam is discharged from the upper steam exhaust pipe 10, and the water is discharged from the lower drain port.
[0028] Specifically, four groups of drain inlets 2 are provided. The advantage is that by providing four groups of drain inlets 2, the drain can enter uniformly on the circumference, so that the steam in the drain can uniformly contact the guide plate 5, thereby improving the working efficiency of the expander body 1.
[0029] Specifically, two groups of guide plates 5 are provided, and both groups of guide plates 5 are inclined. The advantage is that by providing the guide plates 5, the path through which the hydrophobic flow passes is extended, thereby further improving the release of heat. Also, because the guide plates 5 are inclined, the condensed water drips to the lower part of the expansion vessel body 1 due to its own weight, and can then be discharged through the drain pipe 11.
[0030] Specifically, the cooling tube 6 is filled with cooling liquid for circulation. The advantage is that the cooling liquid in the cooling tube 6 exchanges heat with the steam to condense the steam into water, thereby achieving the purpose of cooling.
[0031] Specifically, the outer wall of the exhaust pipe 10 is wrapped with a micro-perforated plate muffler 12. The advantage is that the provision of the micro-perforated plate muffler 12 further plays a role in eliminating airflow noise, thereby meeting the low-noise working requirements.
[0032] When in use, the drain in the pressure pipeline is transported to the expansion tank body 1 through the drain inlet 2 for expansion and pressure reduction, and the drain and steam are separated. The drain is discharged to the outside through the drain pipe 11, and the separated steam rises and is discharged in sequence through the guide plate 5, the blade 9, the micro-perforated plate muffler 12 and the exhaust pipe 10. During the discharge of high-temperature steam, cooling water is input into the cold water pipe 3, and the cooling water is sprayed into the expansion tank body 1 through the nozzle 4. The cooling water contacts the high-temperature steam, thereby achieving the purpose of preliminary cooling of the high-temperature steam. By setting the guide plate 5, the path through which the drain flows is extended, thereby further improving the release of heat. Because the guide plate 5 is inclined, the coolant in the cooling pipe 6 exchanges heat with the steam to realize the condensation of the steam into water. The condensed water drips to the lower part of the expansion vessel body 1 due to its own weight, and then can be discharged through the drain pipe 11, thereby achieving the purpose of secondary cooling. At the same time, the motor 7 is started, the motor 7 drives the shaft 8 to rotate, and the rotation of the shaft 8 drives the blade 9 to rotate. The rotation of the blade 9 can disperse the steam, reduce the exhaust steam volume flow, and greatly reduce the working pressure of the expansion vessel body 1.
