Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of throttling, and in particular relates to a steam pipeline throttling device. Background Art
[0002] When steam is used in the distillation, synthesis and pyrolysis stations of the synthesis workshop, the distillation station requires that the distillation temperature of the ammonium sulfate mother liquor be increased to 90-100°C, and then the pulped lightly burned magnesium oxide material is added. The distillate is kept boiling during the feeding process, and the feeding time is controlled at 30-90 minutes. After the feeding is completed, the temperature is controlled at 90-100°C, and the distillation continues for 3-6 hours. When steam is used at the three stations at the same time, the steam valve at the distillation station is opened widely to ensure the temperature of the distillate. However, when the synthesis and pyrolysis are completed and the steam is deheated, the distillation station has sufficient steam, and the air intake suddenly increases, causing the distillate temperature to rise sharply, and the distillate overflows the tank, and even enters the distillation condenser, causing material leakage. The distillate entering the condenser due to ammonia will corrode the condenser. Utility Model Content
[0003] In order to solve the problems mentioned in the above background technology, the purpose of the utility model is to provide a steam pipeline throttling device, which always ensures the safe pressure of steam use, ensures that the distillation is not flooded, and does not cause material leakage and condenser corrosion.
[0004] The utility model discloses a steam pipeline throttling device, comprising an inlet pipe, a branch pipe 1, a branch pipe 2, a pipeline valve 1, a steam throttler, a pipeline valve 2, a manual steam controller, an outlet pipe, a first anti-reverse valve and a second anti-reverse valve; one end of the inlet pipe is respectively connected with the branch pipe 1 and the branch pipe 2, the other ends of the branch pipe 1 and the branch pipe 2 are both connected with the outlet pipe, the branch pipe 1 is respectively equipped with the pipeline valve 1, the steam throttler and the first anti-reverse valve, and the branch pipe 2 is respectively equipped with the pipeline valve 2, the manual steam controller and the second anti-reverse valve.
[0005] Preferably, the pipeline valve 1 and pipeline valve 2 are both manual valves.
[0006] Preferably, a main valve is installed on the inlet pipe.
[0007] Compared with the prior art, the utility model has the following beneficial effects: two-way control is achieved through the inlet pipe, branch pipe 1, branch pipe 2, pipeline valve 1, steam throttle, pipeline valve 2, manual steam controller, and outlet pipe, which can ensure the safe pressure of steam use and ensure that distillation is not flooded. The specific advantages are:
[0008] 1. When steam is used at three locations in the synthesis workshop at the same time, the manual steam controller is turned on for heating during the initial distillate heating stage (when the distillate temperature is <90°C).
[0009] 2. When the temperature reaches 90℃, the distillation steam opens the throttle pipe to control the steam pressure, always ensuring the safe pressure for steam use, ensuring that the distillation is not flooded, and that there is no material leakage and condenser corrosion.

[0014] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects that can be produced by the utility model and the purposes that can be achieved, should still fall within the scope of the technical content disclosed by the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0015] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0016] like Figure 1As shown, this specific implementation adopts two ways to achieve switching, which can ensure that distillation is not flooded, and specifically adopts the following technical scheme: including an inlet pipe 1, a branch pipe 1 2, a branch pipe 2 3, a pipeline valve 1 4, a steam throttle 5, a pipeline valve 2 6, a manual steam controller 7, an outlet pipe 8, an anti-reverse valve 1 9, and an anti-reverse valve 2 10; the inlet pipe 1 is equipped with a main valve 1-1, and one end of the inlet pipe 1 is respectively connected to the branch pipe 1 2 and the branch pipe 2 3, and two ways are adopted to achieve switching. The other ends of the branch pipe 1 2 and the branch pipe 2 3 are both connected to the outlet pipe 8, and the branch pipe 1 2 is respectively equipped with a pipeline valve 1 4, a steam throttle 5, and an anti-reverse valve 1 9, and the branch pipe 2 3 is respectively equipped with a pipeline valve 2 6, a manual steam controller 7, and an anti-reverse valve 2 10; the pipeline valve 1 4 and the pipeline valve 2 6 are both manual valves, and the steam throttle 5 is a method of adjusting and controlling the steam size by an induction solenoid valve to keep the liquid in the distillation tank slightly boiling without flooding.
[0017] In this specific implementation, a steam throttle device is added to the distillation steam pipeline, and its inlet pipe 1 and outlet 8 are respectively connected to the distillation steam pipeline. At the same time, the steam throttle device is divided into two pipelines, namely branch pipe 1 2 and branch pipe 2 3: a steam throttle 5 is installed on branch pipe 1 2, and a manual steam controller 7 is installed on branch pipe 2 3. When steam is used at three places in the synthesis workshop at the same time, the manual steam controller 7 is turned on for heating in the initial distillate heating stage (when the distillate temperature is <90°C); when the temperature reaches 90°C, the distillation steam turns on branch pipe 1 2, and the steam pressure is controlled by the steam throttle 5: it is controlled to not exceed 0.25Mpa during feeding, and it is controlled to not exceed 0.1Mpa after the feeding is completed; when steam is not used for synthesis and pyrolysis, the steam at the distillation station is controlled by a throttle valve, and the safe pressure of steam use is always guaranteed, and distillation is not flooded. Purpose: The steam at the distillation station is controlled by a throttle valve, and the safe pressure of steam use is always guaranteed, and distillation is not flooded, and material leakage and condenser corrosion do not occur.
[0018] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
[0019] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
