Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a steam-water separator disclosed in the embodiment of the present application includes a housing 1, separation regions 2, a separator 3, an input end 4, an output end 5, and a drainage pipe 6, where a posture of the housing 1 vertically placed on a horizontal plane is taken as a reference, the separation regions 2 are sequentially disposed in the housing 1 from bottom to top, each separation region 2 includes a drainage layer 21 and a diversion layer 22, and the drainage layer 21 is located below the diversion layer 22.
In some possible implementations, a plurality of plates are fixedly mounted in the housing 1, and these plates divide the area in the housing 1 to form the separation zone 2 composed of the drainage layer 21 and the diversion layer 22.
Referring to fig. 1 and 2, the separator 3 is disposed in the casing 1 and is used for separating water from saturated steam flowing into the casing 1, and specifically, the separator 3 has an input end, a liquid output end and a gaseous output end, the input end is located on a side wall of the separator 3, so that the saturated steam flowing into the separator 3 can make a circular motion along an inner wall of the separator 3, and under the action of centrifugal force, moisture of the saturated steam contacts with the inner wall of the separator 3 and slides down along the inner wall of the separator 3, and finally flows out from the liquid output end of the separator 3. The separated vapor flows out of the gaseous output of the separator 3.
The separators 3 are divided into a plurality of groups, the number of the separators 3 in each group is a plurality, each group of the separators 3 is arranged in one separation area 2, the specific mode is that in the direction from bottom to top, the input end of the separator 3 is communicated with the flow guide layer 22 of the next separator 3, the liquid output end is communicated with the drainage layer 21 of the next separator 3, the gaseous output end is communicated with the flow guide layer 22 of the previous separator 3, and the gaseous output end of the separator 3 at the uppermost layer is communicated with the space in the shell 1.
When viewed from the input end 4, the input end 4 is disposed on the housing 1 and is in a direction from bottom to top, and the input end 4 is communicated with the diversion layer 22 of the first separation zone 2, that is, the saturated steam flows into the diversion layer 22 in the lowest separation zone 2 from the input end 4 and then sequentially passes through each separation zone 2 from bottom to top under the guidance of the separator 3. In this process, the moisture in the steam is gradually separated.
Referring to fig. 3 and 4, in conjunction with a specific process, saturated steam flows into the interior of the shell 1 through the input end 4, first enters the diversion layer 22 in the separation zone 2 at the bottom layer, and then enters the plurality of separators 3 connected to the diversion layer 22.
After separation by the separator 3, the separated water flows into the drainage layer 21 below the diversion layer 22 and is discharged from the drainage pipeline 6, and the separated steam enters the separation zone 2 of the previous layer for secondary separation, and the process of secondary separation is the same as that described in the above description, and is not described again here. After multiple times of separation, the moisture in the steam is greatly reduced and finally flows out from the output end 5 on the shell 1,
in summary, the steam-water separator disclosed in the embodiment of the present application, with the help of the multi-component separator 3, can enable the steam flowing into the diversion layer 22 to flow rapidly, so as not to generate a large back pressure, and at the same time, the steam flowing into the separator 3 also makes a circular motion along the inner wall of the separator 3, so that the speed loss is small, and the multi-component separator 3 dispersed at different heights can be used for performing multiple separations on the steam, so as to effectively reduce the moisture in the steam.
Referring to fig. 1, in an embodiment of the steam-water separator, a bottom surface of the flow guide layer 22 is a plane, a bottom surface of the drainage layer 21 is an inclined surface, and one end of the bottom surface of the drainage layer 21 close to the drainage pipeline 6 is lower than the other end, so that accumulated water in the drainage layer 21 can be quickly drained without being retained.
Referring to fig. 5, as a specific embodiment of the steam-water separator provided by the application, a spiral flow guide plate 23 is disposed on the bottom surface of the flow guide layer 22, and the separators 3 in the flow guide layer 22 are sequentially disposed along the spiral flow guide plate 23.
In this way, for the diversion layer 22 at the lowest layer, the steam flowing into the diversion layer 22 flows back to rotate along the spiral diversion plate 23 and uniformly flows into each separator 3, and the flow velocity loss of the steam can be further reduced; for the flow guiding layer 22 of the other layer, the corresponding relation of the separator 3 can be made clear, that is, the steam flowing out from the lower separator 3 enters the upper separator 3, and the flow rate loss can also be reduced, because the steam does not need to enter the flow guiding layer 22 first and then be distributed in the flow guiding layer 22.
Referring to fig. 6, as an embodiment of the steam-water separator provided by the application, in the bottom-up direction, the gaseous output end of the next separator 3 faces the input end of the previous separator 3, that is, in the bottom-up direction, the steam sprayed from the next separator 3 can rapidly enter the previous separator 3 for separation, so that the speed loss of the steam can be minimized.
Further, referring to fig. 6, in the direction from bottom to top, the gaseous output end of the next separator 3 extends into the interior of the input end of the matching previous separator 3.
Referring to fig. 1, as a specific embodiment of the steam-water separator provided by the application, a pressure relief portion 7 is further added, where the pressure relief portion 7 is composed of a pressure relief pipeline 71, a pressure valve 72 and a one-way valve 73, a first end of the pressure relief pipeline 71 is connected to the casing 1 and is communicated with the diversion layer 22 on the separation region 2, and a second end of the pressure relief pipeline 71 is connected to the input end 4, and is used for reintroducing the redundant steam in the diversion layer 22 to the input end 4.
It will be appreciated that if the pressure in the diversion layer 22 is too great, this will result in an increase in back pressure, in particular a decrease in the flow rate of steam in the diversion layer 22, which will significantly reduce the process rate, and therefore require adjustment of the air pressure in the diversion layer 22 via the pressure relief conduit 71 to fluctuate within a suitable range.
The pressure valve 72 and the check valve 73 are both installed on the pressure relief pipe 71, the pressure valve 72 is an opening valve and automatically opens when the air pressure in the diversion layer 22 exceeds a permissible value, and the check valve 73 prevents the steam at the input end 4 from flowing into the pressure relief pipe 71, so that the pressure valve 72 needs to be located in front of the check valve 73 in the air flow direction in the pressure relief pipe 71.
Referring to fig. 7, if the spiral flow guide plate 23 is present in the diversion layer 22, the first end of the pressure relief pipe 71 passes through the casing 1, passes through the drainage layer 21, and then extends out of the center of the diversion layer 22.
Referring to fig. 1, as an embodiment of the steam-water separator provided by the application, a housing 1 includes a barrel portion 11 and a cone portion 12 disposed on the barrel portion 11, wherein a separation region 2 is located in the barrel portion 11, and an output end 5 is connected to a highest portion of the cone portion 12.
The conical part 12 serves to guide the separated steam to the output end 5, and can further reduce the flow rate loss of the steam.
Referring to fig. 1, as a specific embodiment of the steam-water separator provided by the application, an annular guide groove 121 is formed on an inner wall of the conical portion 12, and guide fins 122 are uniformly distributed on the inner wall of the conical portion 12, and the guide fins 122 are located between a connection position of the output end 5 and the conical portion 12 and the annular guide groove 121 and are uniformly arranged around an axis of the conical portion 12.
The steam flowing into the conical portion 12 contacts the inner wall of the conical portion 12 and the guide fins 122, and then water drops are generated on the inner wall of the conical portion 12 and the guide fins 122, and the water drops flow into the annular guide grooves 121.
Accumulated water in the annular diversion trench 121 is discharged through the liquid level sensor 123 and the electric control valve 134, the liquid level sensor 123 is located on the inner wall of the conical part 12 and located on the outer wall of the conical part 12, the control end of the electric control valve 134 is connected with the signal output end of the liquid level sensor 123, the input end of the electric control valve 134 is communicated with the annular diversion trench 121, and the output end of the electric control valve is communicated with the space outside the shell 1.
When the height of the accumulated water in the annular diversion trench 121 reaches a set value, the liquid level sensor 123 feeds back a signal, the electric control valve 134 receives the signal and then switches from a closed state to an open state, at the moment, the accumulated water in the annular diversion trench 121 flows out through the electric control valve 134, and after drainage is finished, the electric control valve 134 is closed.
In some possible implementations, the opening time of the electronically controlled valve 134 is set.
