Description

Technical Field

[0001] The utility model relates to the technical field of steam stripping system application, in particular to a mixing device for steam and condensed water. Background Art

[0002] A stripping system uses steam or other gases to pass through a liquid to reduce the partial pressure of light components, causing them to evaporate and be removed. This process is based on Dalton's law of partial pressures and Raoult's law. A typical stripping system consists of a stripping tower, condenser, gas-liquid separator, and pump. The stripping tower is the core component, and its internal structure design has a significant impact on mass transfer efficiency.

[0003] The original steam and condensate pipes are merged into a unified pipe and then enter the stripping system. Due to the brushing phenomenon in the pipes, especially at the elbows, the pipe walls are easily thinned, which eventually leads to leakage and causes the entire system to stop. Therefore, the utility model proposes a mixing device for steam and condensate. Utility Model Content

By adding a mixing chamber at the mixing point of steam and condensate, the scouring of the pipeline by steam can be reduced, the service life of the pipeline can be extended, the normal production time can be extended, and the use efficiency of steam can be improved.

[0005] To solve the above technical problems, the present invention adopts a technical solution: providing a mixing device for steam and condensate, comprising a mixing chamber, one end of which is sealed and welded with a condensate conduit, the other end of which is sealed and welded with a mixture discharge pipe, and the bottom of which is sealed and welded with a steam conduit, which extends into the interior of the mixing chamber;

[0006] The mixing chamber is chamfered near the end surface, the steam conduit is in an inverted L shape, and the end surface of the mixture discharge pipe is connected to an external stripping system.

[0007] The utility model is further configured as follows: the end faces of the mixing chamber are symmetrically and fixedly connected with end face connecting flanges, and the two end face connecting flanges are respectively sealed and welded to the condensate conduit and the mixture discharge pipe.

[0008] The above technical solution facilitates the condensate conduit to be stably connected and fixed to the end face of the mixing chamber through the end face connecting flange, thereby facilitating the circulation of the internal condensate.

[0009] The utility model is further configured as follows: the end face of the condensate conduit away from the mixing chamber is sealed and connected with a connecting valve.

[0010] The above technical solution makes it easy to use the connecting valve to open and close the condensate pipe so that it can circulate with steam.

[0011] The utility model is further configured as follows: a plurality of spiral grooves are evenly opened in the circumferential direction of the inner portion of the mixture discharge pipe.

[0012] The above technical solution facilitates mixing inside the mixing chamber, and further mixing of the steam and condensate after discharge together under the further action of the spiral groove, thereby improving the mixing effect of the steam and condensate.

[0013] The utility model is further configured as follows: a fixed flange is fixedly connected to the outer wall of the steam conduit near the middle position, and the fixed flange is sealed and welded to the bottom connecting flange fixedly connected to the end surface position at the bottom of the mixing chamber.

[0014] With the above technical solution, after the steam conduit is inserted into the mixing chamber, the steam conduit can be stably mounted on the bottom connecting flange for fixation using the fixing flange.

[0015] The utility model is further configured as follows: two groups of nozzles are fixedly connected to the horizontal bending portion at the top of the steam conduit, and the two groups of nozzles are respectively installed on the upper and lower surfaces of the bending portion, and each group is configured with three nozzles.

[0016] The above technical solution facilitates the rapid spraying of steam in the steam conduit into the mixing chamber through a plurality of nozzles to quickly mix the steam with the incoming condensate.

[0017] The utility model is further configured as follows: the bottom of the steam conduit is threadedly connected to a connecting port, and the bottom of the connecting port is fixedly connected to a limiting sealing ring.

[0018] The above technical solution facilitates the connection and sealing of the external steam pipe through the limiting sealing ring to prevent leakage, and the steam can be guided to the interior of the mixing chamber through the connection port.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model proposes a mixing device for steam and condensate, which adds a mixing chamber at the mixing point of steam and condensate, thereby reducing the scouring of the pipeline by steam, extending the service life of the pipeline, extending the normal production time, and improving the use efficiency of steam.

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0027] like Figure 1-Figure 3 As shown, a mixing device for steam and condensate includes a mixing chamber 1, an end face of the mixing chamber 1 is symmetrically fixedly connected with an end face connecting flange 12, and the two end face connecting flanges 12 are respectively sealed and welded with the condensate conduit 2 and the mixture discharge pipe 3, so that the condensate conduit 2 is stably connected and fixed to the end face of the mixing chamber 1 through the end face connecting flange 12, which facilitates the circulation of the internal condensate. One end of the mixing chamber 1 is sealed and welded with the condensate conduit 2, and the end face of the condensate conduit 2 away from the mixing chamber 1 is sealed and connected with a connecting valve 21, so that the condensate conduit 2 can be connected to the condensate conduit 2 using the connecting valve 21. The channel is opened and closed to cooperate with the steam to circulate. The other end face of the mixing chamber 1 is sealed and welded with a mixture discharge pipe 3. A plurality of spiral grooves 31 are evenly opened in the inner circumferential direction of the mixture discharge pipe 3, which is convenient for mixing inside the mixing chamber 1. Under the further action of the spiral grooves 31, the steam and condensate are discharged together and further mixed, thereby improving the mixing effect of the steam and condensate. The mixing chamber 1 is chamfered near the end face, and the steam conduit 4 is in an inverted L shape. The end face of the mixture discharge pipe 3 is connected to the external steam stripping system.

[0028] like Figure 4As shown, a steam conduit 4 is seal-welded at the bottom of the mixing chamber 1, and the steam conduit 4 extends into the interior of the mixing chamber 1. Two sets of nozzles 41 are fixedly connected to the horizontal bend at the top of the steam conduit 4, and the two sets of nozzles 41 are respectively installed on the upper and lower sides of the bend. At the same time, there are three nozzles, so that the steam inside the steam conduit 4 can be quickly sprayed into the interior of the mixing chamber 1 through multiple nozzles 41 to quickly mix with the incoming condensate. A fixing flange 42 is fixedly connected to the outer wall of the steam conduit 4 near the middle position, and is seal-welded to the bottom connecting flange 11 fixedly connected to the bottom of the mixing chamber 1 near the end surface through the fixing flange 42, so that after the steam conduit 4 is inserted into the interior of the mixing chamber 1, the steam conduit 4 can be stably installed on the bottom connecting flange 11 using the fixing flange 42. A connection port 43 is threadedly connected to the bottom of the steam conduit 4, and a limiting sealing ring 44 is fixedly connected to the bottom of the connection port 43, so that when the external steam pipe is connected, it can be connected and sealed through the limiting sealing ring 44 to prevent leakage, and the steam can be directed to the interior of the mixing chamber 1 through the connection port 43.

[0029] When the present invention is in use, the steam conduit 4 is first inserted into the interior of the mixing chamber 1 through the opening at the bottom of the mixing chamber 1, and is sealed and welded to the bottom connecting flange 11 using a fixed flange 42. Then, the condensate conduit 2 and the steam conduit 4 are connected, so that the condensate and steam are mixed inside the mixing chamber 1, and are discharged through the mixture discharge pipe 3 after mixing. At the same time, under the action of the spiral groove 31 inside the mixture discharge pipe 3, the mixed mixture is further mixed, thereby improving the mixing effect of the condensate and steam, and finally discharged into the external steam stripping system through the mixture discharge pipe 3.
