Background
At present, a sludge dryer used in the sludge treatment industry mostly adopts water vapor as an indirect heating medium of sludge. During drying, steam and mud indirect heat exchange, heat transfer in the steam for mud for the temperature reduction of steam becomes steam condensate, and steam condensate is discharged and is gathered to the ordinary pressure water tank through the trap on the mud desiccator condensate pipe way. However, in the steam condensate pipeline from the steam trap to the normal-pressure water tank, secondary flash evaporation is generated after steam condensate passes through the steam trap, so that a mixture of secondary steam and hot water is released, and the operation of a water pump in a subsequent working section is influenced without separation, thereby causing cavitation erosion of the water pump.
In order to ensure the normal operation of subsequent process equipment, a vertically arranged steam-water separation device is arranged in the section of pipeline to separate the mixture of secondary steam and hot water. When the vertically arranged steam-water separation device works, a mixture of secondary steam and hot water enters from the top of the steam-water separation device, the separated hot water is discharged from the bottom, and the steam is discharged from the top. The device utilizes that water is bigger than steam density, and under the action of gravity, hot water sinks in the bottom of device, and steam floats on the top of device to realize the separation of secondary steam and hot water.
However, the pipeline arrangement of the steam-water separation device is complex, so that the occupied area is large generally; in addition, the conventional steam-water separation device is provided with a steam-water mixture (a mixture of secondary steam and hot water) introduced from the top, and since the steam-water mixture inlet is communicated with the upstream dryer steam condensate outlet, if the steam-water mixture can flow to the steam-water separation device, the height of the dryer steam condensate drain valve outlet needs to be higher than that of the steam-water mixture inlet and at least needs to be consistent with that of the steam-water mixture inlet, so that the foundation of the dryer needs to be raised. If the base of the dryer is not lifted, the water pump needs to be added, and the increase of the water pump steam-water mixture can cause serious cavitation of the water pump.

Detailed Description
The present invention will be described more specifically and further illustrated with reference to specific examples, which are by no means intended to limit the scope of the present invention.
The steam-water separation device for the steam condensation water pipeline provided by the utility model has the structure as shown in fig. 1 and 2, and is a horizontally arranged pipeline from a drain valve on the steam condensation water pipeline, namely a sludge dryer condensation water pipeline, to a normal pressure water tank. The steam-water separation device comprises a main body 4, wherein a steam-water mixture inlet 1 is formed in one side of the bottom of the main body 4, and a hot water outlet 2 is formed in the other side of the bottom of the main body 4, namely the hot water outlet 2 is arranged opposite to the steam-water mixture inlet 1; the steam-water mixture inlet 1 is connected with the upstream of the steam condensate pipeline (namely, connected with the side of a drain valve), and the hot water outlet is connected with the downstream of the steam condensate pipeline (namely, connected with the side of a normal-pressure water tank); the steam-water mixture inlet 1, the hot water outlet 2 and the steam condensate pipeline are arranged on the same horizontal line, and no height difference exists in the vertical direction; or the steam-water mixture inlet 1 and the steam condensate pipeline have the same height, but the hot water outlet 2 is slightly lower than the steam-water mixture inlet 1. The top of the main body 4 is provided with a steam outlet 3, and the steam outlet 3 is directly communicated with the atmosphere or connected with other equipment which can utilize the steam.
The body 4 is generally cylindrical or rectangular in shape (including the height and cross-sectional size of the particular shape) selected according to the actual operating space. The bottom surface of the main body 4 is flush with the bottom surface of the steam condensation pipeline, the height H in the vertical direction is higher than the pipe diameter D of the steam condensation pipeline, and generally H is (4-5) D. A backflow plate 5 is horizontally arranged in the main body 4, a plurality of through holes are formed in the backflow plate 5, and the height h between the backflow plate 5 and the bottom surface of the main body 4 is larger than D. The periphery of the backflow plate 5 is connected with the inner wall of the main body 4, so that the backflow plate 5 and the middle upper part of the main body 4 enclose a relatively closed chamber 6, and the chamber 6 takes the backflow plate 5 as the bottom and the main body 4 as the top and the side wall. A plurality of stainless steel wire balls are contained in the chamber 6 and used for preventing fine water particles in the steam-water mixture from rising; the filling density degree of the stainless steel wire balls can be adjusted according to the actual steam-water separation amount, for example, when the quantity of the steam-water mixture to be separated is large, the stainless steel wire balls need to be filled tightly, and when the quantity of the steam-water mixture to be separated is small, the stainless steel wire balls can be filled sparsely.
The working principle of the steam-water separation device for the steam condensate pipeline is as follows: the steam condensate flows out of a drain valve of the condensate pipeline of the sludge dryer and enters a steam condensate pipeline leading to the normal-pressure water tank. The pressure in the steam condensation water pipeline is lower than that in the condensation water pipeline, so that the steam condensation water is converted into a steam-water mixture containing secondary steam and hot water. The steam-water separation device is arranged on the steam condensation pipeline, and a steam-water mixture is bound to pass through the steam-water separation device in the process of flowing to the normal-pressure water tank. After the steam-water mixture enters the main body 4 of the steam-water separation device of the utility model from the steam-water mixture inlet 1, most hot water is positioned at the bottom of the main body 4 and is discharged from the hot water outlet 2 due to the action of gravity; the steam and fine water particles float upwards and pass through the through holes on the return plate 5 into the chamber 6. The water particles are blocked by stainless steel wire balls in the chamber 6, the water particles are condensed and converged into water drops under the combined action of blocking and cooling, then flow back to the bottom of the main body 4 through the through holes on the flow returning plate 5, are discharged from the hot water outlet 2 and finally converge to the normal-pressure water tank; the steam continuously floats upwards and is discharged to the atmosphere or other equipment which can utilize the steam from the steam outlet 3, and the separation of the secondary steam and the hot water in the steam condensation pipeline is completed. Because the height of the backflow plate 5 is slightly higher than the upper edges of the steam-water mixture inlet 1 and the hot water outlet 2, only fine water particles and steam can enter the cavity 6, most of hot water cannot enter the cavity 6, which is equivalent to that the backflow plate 5 performs primary separation on the steam-water mixture, and stainless steel wire balls in the cavity 6 further separate the steam-water mixture, so that the separation effect is better.
Therefore, the steam-water separation device has the advantages of simple structure, small occupied area, no need of changing the height of the original steam condensate pipeline, no fuel, no power consumption of a motor, a water pump and the like, and the like.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the content of the present invention.
