Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and particularly relates to a steam-water separation device and a reaction kettle. Background Technique

[0002] Chemical equipment is the general term for machines and equipment used in chemical industry production. Its main functional components are static or have very little movement machinery, such as various containers (tanks, pots, kettles, etc.), ordinary kilns, tower apparatuses, reactors, heat exchangers, ordinary dryers, evaporators, reaction furnaces, electrolytic cells, crystallization equipment, mass transfer equipment, adsorption equipment, fluidized bed equipment, ordinary separation equipment, and ion exchange equipment, etc. Among them, the reaction kettle is a device used for chemical reactions, physicochemical processes, and laboratory research. It is usually made of steel plates with a certain thickness and has high corrosion resistance and the ability to withstand high temperature and high pressure. When the reaction kettle is heated up, most of them use high-temperature heat-conducting oil or steam introduced into the jacket to complete. At present, the steam introduced into the jacket usually uses a steam trap to achieve the separation of steam and water and the energy saving of steam. In actual use, although the steam trap can play a certain role, it is extremely easy to cause serious steam waste problems due to the high failure rate and short service life of the steam trap.

[0003] There are studies in the prior art on the serious waste of steam during the steam-water separation of the steam in the jacket. For example, in the patent CN208194367U - A chemical reaction waste heat steam recycling oven system, after the waste heat steam is separated by a steam-water separator and then introduced into the oven, the recovery and utilization of the steam heat are realized, and the problem of serious waste of steam during the steam-water separation of the current steam in the jacket is solved. However, the existing steam recycling device can only ensure the recovery and utilization of steam heat, but it is very difficult to effectively control the consumption of the steam in the jacket, and it is very difficult to meet the increasing efficiency requirements of steam energy conservation. Therefore, a new technical solution is needed to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a steam-water separation device and a reaction kettle to solve the problems in the above background technique that it is very difficult to effectively control the consumption of the steam in the jacket of the current reaction kettle, resulting in difficulty in meeting the increasing efficiency requirements of steam energy conservation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steam-water separation device, comprising a separator, the top of the separator is sealed and connected with a cover plate, the inner middle part of the separator is provided with a hole tube area, a plurality of triangular hole tubes with a honeycomb structure are provided in the hole tube area, and two adjacent triangular hole tubes in a row are arranged in opposite directions, a steam flow area connected to the top of the triangular hole tube is provided in the inner upper part of the separator, a condensate collection area connected to the bottom of the triangular hole tube is provided in the inner lower part of the separator, an injection pipe connected to the condensate collection area is fixed on the outer lower wall of the separator, a plurality of nozzles arranged in an array are provided through the injection pipe, a flow regulating valve is connected to the injection pipe at the rear and is connected to a condensate discharge pipe through the flow regulating valve, a bypass pipe is connected to the condensate discharge pipe and is connected to a straight discharge port at the bottom of the condensate collection area through the bypass pipe.

[0006] Furthermore, a steam pipe is externally connected to one side wall of the separator, a ball valve is connected to the steam pipe and the steam pipe is connected to the steam flow zone through the ball valve, and the lower outside of the other side wall of the separator is connected to the condensate discharge pipe.

[0007] Furthermore, one end of the condensate discharge pipe is connected to the condensate collection area through a flow regulating valve and an injection pipe, the other end of the condensate discharge pipe is connected to a condensate collecting tank, the side of the condensate discharge pipe is connected to a bypass pipe, one end of the bypass pipe is connected to the condensate discharge pipe and is arranged on the rear end side of the flow regulating valve, the other end of the bypass pipe is connected to a direct discharge valve and is connected to a direct discharge port on one side of the bottom of the condensate collection area through the direct discharge valve, a sewage outlet is opened on the other side of the bottom of the condensate collection area, the sewage outlet is connected to a sewage valve, and the setting position of the sewage outlet is lower than the setting position of the direct discharge port.

[0008] In addition to the above technical solutions, there is also a reactor with the steam-water separation device, and the steam-water separation device is connected to the steam jacket of the reactor through a steam pipe.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The present utility model adopts the setting of triangular hole pipes with a honeycomb structure, so that when steam flows into the triangular hole pipes, it is divided into countless tiny steam flows, effectively expanding the contact area between the tiny steam flows and the wall of the hole pipe area. Thus, the steam-water separation device has the wall effect. Using the principle of the wall effect, countless tiny steam flows are cooled to form condensed water and flow into the condensed water collection area. In the early stage, it is discharged into the condensed water discharge pipe through the bypass pipe, and in the later stage, the bypass pipe is closed and it is discharged into the condensed water discharge pipe through the injection pipe and the flow regulating valve. By setting the injection pipe connected to the rear end of the condensed water collection area, the steam that has not condensed when passing through the triangular hole pipe (hereinafter referred to as residual steam) can flow from the large-diameter condensed water collection area to the small-diameter injection pipe. Thus, the steam-water separation device has the adiabatic expansion and Joule-Thomson effects. Using the adiabatic expansion and Joule-Thomson effects, the residual steam condenses into condensed water when flowing out of the small-diameter injection pipe and flows into the condensed water discharge pipe. Then, by using the regulating function of the flow regulating valve, the residual steam can be converted into condensed water and discharged to the maximum extent, ensuring that all the steam can be condensed into water, greatly reducing the difficulty of recovering and utilizing steam condensed water. Thus, the steam-water separation device can effectively control the consumption of steam, and the consumption of steam is reduced by at least more than 5%, effectively improving the stability and service life of the separator, meeting the demand for increasing efficiency in steam energy conservation, and at the same time solving the problem of high ambient temperature at the production site caused by "smoking" in the steam condensed water system;

[0011] 2. The present utility model adopts the setting of nozzles arranged in an array, so that the injection pipe can adjust the number of nozzles in circulation under the regulation of the flow regulating valve, so that the flow rates of both the condensed water and the residual steam are within the controllable range, achieving the purpose of saving steam and reducing the impact on the ambient temperature;

[0012] 3. The present utility model, by setting the flow regulating valve connected to the injection pipe, enables the residual steam to be converted into condensed water and discharged to the maximum extent when the opening of the flow regulating valve is large, and at the same time can reduce the flow area of the injection pipe when the opening of the flow regulating valve is small, so that the steam can fully achieve heat exchange, greatly improving the efficiency of steam use;

[0013] 4. The present utility model, by setting a bypass pipe on the condensed water collection area, enables a large amount of condensed water generated at the initial stage of heating when the temperature of the reaction kettle jacket is low at the beginning of the separator's operation to be quickly discharged through the bypass pipe. By setting the position of the sewage outlet lower than the position of the direct discharge port, impurities that may exist in the separator can be quickly discharged under the action of the sewage valve, effectively improving the purity of the condensed water collection.

[0021] The following embodiments are used to further illustrate the content of the present utility model and do not limit the application of the present utility model. Embodiment 1:

[0022] Please refer to Figures 1 - 5, A steam-water separation device, including a separator 1 for steam-water separation. A cover plate 10 for sealing is hermetically connected to the top of the separator 1. In the middle part inside the separator 1, there is a hole tube area 2 for steam flow. Inside the hole tube area 2, there are several triangular hole tubes 3 arranged in a honeycomb structure and used to generate wall effects, so that steam can only flow through the triangular hole tubes 3. Two adjacent triangular hole tubes 3 in a row are arranged in opposite directions. The top of the triangular hole tube 3 is connected to a steam flow conversion area 4 arranged in the upper part inside the separator 1 and used for steam to enter. The steam flow conversion area 4 is connected to a steam pipe 11 arranged outside one side wall of the separator 1. A ball valve 12 is connected to the steam pipe 11. The bottom of the triangular hole tube 3 is connected to a condensate collection area 5 arranged in the lower part inside the separator 1 and used for condensate flow. A jet pipe 6 for generating adiabatic expansion and Joule-Thomson effects and communicating with the condensate collection area 5 is fixed on the outer lower wall of the separator 1. Inside the jet pipe 6, there are several nozzles 601 arranged in an array. After the jet pipe 6, there is a flow regulating valve 7 for regulating the flow rates of condensate and residual steam, and through the flow regulating valve 7, it is connected to a condensate discharge pipe 8 arranged outside the other side wall of the separator 1 and used for discharging condensate. A bypass pipe 9 for directly discharging the condensate in the condensate collection area 5 is connected to the condensate discharge pipe 8 and is connected to the direct discharge port 501 at the bottom of the condensate collection area 5 through the bypass pipe 9.

[0023] Please refer to Figure 1 and Figures 4 - 5 , One end of the condensate discharge pipe 8 is connected to the condensate collection area 5 through the flow regulating valve 7 and the jet pipe 6. The other end of the condensate discharge pipe 8 is connected to a condensate collection tank 13 for collecting and recycling steam condensate. The side part of the condensate discharge pipe 8 is connected to the bypass pipe 9.

[0024] One end of the bypass pipe 9 is connected to the condensate discharge pipe 8 and is arranged on the rear side of the flow regulating valve 7. The other end of the bypass pipe 9 is connected to a direct discharge valve 14 and is connected to the direct discharge port 501 on one side of the bottom of the condensate collection area 5 through the direct discharge valve 14.

[0025] On the other side of the bottom of the condensate collection area 5, there is a sewage discharge port 502 for discharging impurities inside the separator 1. The sewage discharge port 502 is connected to a sewage discharge valve 15 for controlling the discharge of impurities. The setting position of the sewage discharge port 502 is lower than the setting position of the direct discharge port 501.

[0026] The working principle and usage process of this embodiment: As Figures 1 - 5As shown in the schematic diagram, after the steam-water separation device is assembled, the operator installs the entire steam-water separation device at the steam outlet of the steam jacket 17 outside the reaction kettle 16 through the steam pipe 11. By utilizing the principles of wall effect, adiabatic expansion, and Joule-Thomson effect, the steam temperature is rapidly reduced and condensed into water, thereby achieving steam-water separation. The purpose is to reduce the steam consumption by at least more than 5%, effectively improving the working stability and service life of the separator 1, meeting the demand for energy-saving and efficiency improvement of steam energy, and at the same time solving the problem of high ambient temperature at the production site caused by "smoking" in the steam condensate system;

[0027] When the reaction kettle 16 starts to work, since the temperature inside it is relatively low, a large amount of condensate will be generated. The operator will open the direct drain valve 14 in advance, so that the condensate directly drains into the condensate discharge pipe 8 through the bypass pipe 9, and then drains into the condensate collection tank 13 through the condensate discharge pipe 8. After the temperature of the distillation equipment becomes normal, the direct drain valve 14 is closed. At this time, the steam in the steam jacket 17 outside the reaction kettle 16 enters the steam pipe 11 (as Figure 6 shown by the arrow direction), passes through the ball valve 12 (the ball valve is in the normally open state) and enters the steam flow area 4. The steam entering the steam flow area 4 will be divided into countless small steam flows under the action of the triangular hole pipe 3 with a honeycomb structure. The wall effect is used to cool the countless small steam flows to form condensate and flow into the condensate collection area 5. The condensate will drain into the condensate discharge pipe 8 through the bypass pipe 9. Since there will still be residual steam when the steam flows through the triangular hole pipe 3 and into the condensate collection area 5, the residual steam will flow out from the nozzle 601 of the injection pipe 6. The adiabatic expansion and Joule-Thomson effect are used to condense the residual steam into condensate when it flows out of the small-diameter injection pipe 6 and is controlled by the flow regulating valve 7 to flow into the condensate discharge pipe 8. At this time, all the water flowing out of the condensate discharge pipe 8 is condensate, and finally it drains into the condensate collection tank 13 through the condensate discharge pipe 8 (the flow directions of the steam and condensate are as Figure 1 shown by the arrow direction in the figure);

[0028] When the operator adjusts the flow regulating valve 7, the number of channels in the separator 1 and the flow resistance of the steam at the front end of the separator 1 will increase or decrease through the flow regulating valve 7, so as to achieve the best use effect of the separator 1, and achieve the purpose of saving steam and reducing the impact on the ambient temperature. Specifically: when the opening of the flow regulating valve 7 is adjusted larger, the condensate flowing out from the condensate collection area 5 will increase, and at the same time, the liquid level of the condensate collection area 5 will decrease, and fewer nozzles 601 are submerged, so that the residual steam is maximally converted into condensate and discharged. When the opening of the flow regulating valve 7 is adjusted smaller, the condensate flowing out from the condensate collection area 5 will decrease, and at the same time, the liquid level of the condensate collection area 5 will rise, and more nozzles 601 are submerged, and the flow area of the outflow is reduced, so as to form a pressure space in the separator 1, so that the residence time of the steam in the steam jacket 17 is extended, the heat exchange is fully realized, and the utilization efficiency is greatly improved. Embodiment 2:

[0029] Please refer to Figure 6 , as another object of the present utility model, there is provided a reaction kettle, in which the above-mentioned steam-water separation device is provided in the reaction kettle 16, and the steam-water separation device is connected to the steam jacket 17 outside the reaction kettle 16 through a steam pipe 11. Therefore, the reaction kettle 16 can obtain any beneficial effect of the above-described steam-water separation device, which will not be elaborated here.
