[0002] Exhaust steam is generated during the operation of the deaerator. The exhaust steam still contains a high amount of heat and has considerable utilization value. Direct emission not only causes waste of energy, but also causes thermal pollution to the environment and generates noise. Therefore, it is necessary to use a recovery device to recycle and reuse the exhaust steam from the deaerator.

[0003] The existing patent (publication number: CN218626804U) discloses a waste steam recovery device for a deaerator, comprising a base; a deaerator body, the deaerator body is installed on one side of the top of the base, a water inlet is installed on one side of the top of the deaerator body, and an air outlet is installed on the other side of the top of the deaerator body; the waste heat steam recovery device is installed on the other side of the top of the base, a vent pipe is installed on the top of the air outlet, and a jet component is arranged between the other end of the vent pipe and the top of the waste heat steam recovery device, and the water pump is installed At the top of the base, a water pumping pipe is connected between the water pumping end of the water pump and the bottom end of the waste heat steam recovery device, and a water pipe is connected between the output end of the water pump and the water inlet. Although the device can absorb low-temperature water and waste heat steam through the waste heat steam recovery device to achieve the recycling of resources, the device cannot quickly separate gas and liquid when in use, resulting in the discharge of gas with water, thereby reducing the quality of gas-liquid separation, and at the same time, the efficiency of cooling the exhaust steam is low, and the cooling temperature and flow rate are uncontrollable.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) By setting a separation plate and an exhaust device, the cooled fluid is introduced into the injection coil through the connecting elbow and discharged through the injection coil. After the gas is discharged, it flows upward. The liquid falls downward due to its weight. The liquid will carry a part of the gas when it falls downward. When the liquid contacts the separation plate, the gas and liquid are buffered on the separation plate. The liquid is introduced into several connecting pipes through the holes on the separation plate, and then introduced into the V-shaped groove in the guide plate through the connecting pipe, and then flows into the collection tank. The gas is blocked by the separation plate so that it does not mix with the liquid, so that the gas flows upward. The gas rises and is introduced into the collection box. The gas contacts several arc plates. The liquid carried in the gas adheres to the bottom of the arc plate when contacting the arc plate, and the gas flows upward through the gaps between the arc plates and is discharged through the exhaust pipe.

[0015] (2) A steam-water ejector is set up and installed together with the deaerator through a mounting base. A high-speed fluid is introduced into the exhaust steam discharged from the deaerator to generate a negative pressure effect, so that the exhaust steam is carried away by the steam-water ejector. When the high-speed fluid is ejected into the environment, it will generate a negative pressure area, so that the surrounding air or liquid is attracted in. The new fluid entering the negative pressure area is mixed with the high-speed fluid, thereby achieving a cooling effect and improving the cooling efficiency. The desired cooling effect can be achieved by adjusting the operating parameters of the steam-water ejector, such as flow rate, pressure, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] Embodiment 1:

[0023] See also Figure 1 - Figure 4As shown, a deaerator exhaust steam recovery device comprises a base 1: four support frames 2 are fixedly connected to one side of the top of the base 1 at equal distances, and a steam-water ejector 3 is fixedly connected between the four support frames 2, a mounting seat 4 is fixedly connected to one side of the top of the steam-water ejector 3, a connecting elbow 5 is fixedly connected to one end of the steam-water ejector 3 away from the mounting seat 4, a gas-liquid separation device 6 is fixedly and insertedly connected to one end of the connecting elbow 5 away from the steam-water ejector 3, an exhaust device 7 is installed in the middle of the top of the gas-liquid separation device 6, a controller 8 is fixedly connected to the top of the base 1, and the bottom end of the gas-liquid separation device 6 is fixedly connected to the top of the base 1.

[0024] Depend on Figure 2 and Figure 3 It can be seen that the gas-liquid separation device 6 includes a separation tank 61, a spray coil 62, a separation tower plate 63, a collecting tank 64 and a guide pipe 65. The spray coil 62 is fixedly connected to the upper part of the inner wall of the separation tank 61, the separation tower plate 63 is fixedly connected to the middle part of the inner wall of the separation tank 61, the collecting tank 64 is fixedly connected to the lower part of the inner wall of the separation tank 61, and the bottom end of the collecting tank 64 is fixedly connected to the guide pipe 65. The separation tank 61 is fixedly connected to the base 1 together; the separation tower plate 63 includes a separation plate 631, and a plurality of connecting pipes 632 are fixedly connected to the bottom end of the separation plate 631 at equal distances. Two connecting frames 633 are fixedly connected to the outer surfaces of the connecting pipes 632, and guide plates 634 are fixedly connected between the transverse connecting frames 633. The separation plate 631 is fixedly connected to the inner wall of the separation tank 61 together.

[0025] As can be seen from the above, by installing the mounting base 4 and the deaerator together, a high-speed fluid is introduced into the exhaust steam discharged from the deaerator to generate a negative pressure effect, so that the exhaust steam is taken away by the steam-water ejector 3, and the working parameters of the steam-water ejector 3 are adjusted to ensure that the exhaust steam can be effectively recovered. When the high-speed fluid is injected into the environment, it will generate a negative pressure area, so that the surrounding air or liquid is attracted in. After the new fluid entering the negative pressure area is mixed with the high-speed fluid, a cooling effect is achieved. The cooled fluid is introduced into the injection coil 62 fixedly connected to it through the connecting elbow 5, and is discharged through the injection coil 62. The gas After the liquid is discharged, it flows upward, and the liquid falls downward due to its weight. When the liquid falls downward, it will carry a part of the gas. When the liquid contacts the separation plate 631, the gas and liquid are buffered on the separation plate 631. The liquid is introduced into several connecting pipes 632 through the holes on the separation plate 631, and is introduced into the V-shaped groove in the guide plate 634 through the connecting pipe 632, and then flows into the collection tank 64, and then discharged through the outlet pipe 65 fixedly connected to the collection tank 64 for recycling. The gas is blocked by the separation plate 631, so that it does not mix with the liquid, thereby allowing the gas to flow upward.

[0026] Preferably, one end of the injection coil 62 is fixedly connected with the connecting elbow 5, and the end of the outlet pipe 65 away from the collecting tank 64 passes through one side of the outer surface of the separation tank 61 and extends to the outside; the top of the guide plate 634 is set as a V-shaped groove.

[0027] As can be seen from the above, by connecting the injection coil 62 to the connecting elbow 5, the exhaust steam after cooling by the steam-water ejector 3 can be introduced into the injection coil 62, and by setting the top of the guide plate 634 as a V-shaped groove, the flow of liquid is facilitated.

A number of arc plates 74 are fixedly connected at equal distances between the two sides of the inner wall of the connecting frame 73. The collecting box 71 is installed together with the gas-liquid separation device 6.

[0030] As can be seen from the above, after the gas and liquid are introduced into the separation tank 61, the gas rises and is introduced into the collection box 71, and the gas contacts a plurality of arc plates 74. The liquid carried in the gas adheres to the bottom of the arc plate 74 when contacting the arc plate 74, and the gas flows upward through the gaps between the arc plates 74, opening the valve 75 so that the gas in the collection box 71 is discharged through the exhaust pipe 72.

[0031] Preferably, the plurality of arc plates 74 are all tilted and fixedly connected to the connection frame 73 , and the lower portion of the collection box 71 is movably inserted and connected to the top of the separation tank 61 .

[0032] As can be seen from the above, by installing the arc plate 74 at an angle, the flow of gas is facilitated.
