[0032] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Example

[0034] like Figures 1 to 3 As shown, a steam recovery stabilization system device includes a hydrochloric acid furnace 1, a steam flash tank 2, a gas-liquid separator 3 and a liquid chlorine vaporizer 4, wherein the hydrochloric acid furnace 1, the steam flash tank 2, the gas-liquid separator 3 and the liquid chlorine vaporizer 4 are connected in sequence, a regulating valve 5 is provided between the steam flash tank 2 and the gas-liquid separator 3, and a regulating valve 5 is provided between the gas-liquid separator 3 and the liquid chlorine vaporizer 4;

[0035] Since H2+Cl2=2HCl will release a lot of heat when reacting in the hydrochloric acid furnace 1, the heat generated by the reaction is used to evaporate the soft water. In order to make the steam carry more heat, the production pressure in the steam flash tank 2 is 0.16-0.4MPa. Since the steam pressure of the liquid chlorine vaporizer 4 is controlled at 0.02-0.05MPa during production, the steam pipeline is directly connected, and the pressure difference is large, which will form a large amount of condensate, causing steam fluctuations and affecting production. Under the joint action of the regulating valve 5 arranged between the liquid chlorine vaporizer 4, the high-pressure steam is decompressed twice to the working pressure of the liquid chlorine vaporizer 4 to achieve the stable pressure of the recovered steam. At the same time, the regulating valve 5 arranged between the steam flash tank 2 and the gas-liquid separator 3 can also cooperate with the liquid level meter (not shown in the figure) to adjust the liquid level in the gas-liquid separator 3. This is a conventional technical means and will not be described in detail here. The hydrochloric acid furnace 1, the steam flash tank 2, the gas-liquid separator 3 and the liquid chlorine vaporizer 4 are all conventional equipment in the field and will not be described in detail here.

[0036] The regulating valve 5 includes a three-way valve body 6, a regulating component 7 and a regulating head 8, wherein the regulating component 7 and the regulating head 8 are respectively arranged on both sides of the three-way valve body 6, the regulating component 7 includes an end cap 71, a threaded member 72, a spring 73 and a movable member 74, the threaded member 72 has a first end 721 and a second end 722, the first end 721 of the threaded member 72 is threadedly connected to the three-way valve body 6, the second end 722 of the threaded member 72 is exposed outside the three-way valve body 6 and is provided with the end cap 71, the end cap 71 and the threaded member 72 are threadedly connected, the first end 721 is recessed inwardly to form a rebound groove 723, a fixing column 75 is arranged in the rebound groove 723, the movable member 74 is arranged on the outer surface of the fixing column 75, the movable member 74 is provided with an expansion platform 76 at one end away from the threaded member 72, and the spring 73 is arranged on the outer surface of the movable member 74;

[0037] The fixed column 75 is protruded from the first end 721, and the movable member 74 has a larger movable range on the fixed column 75, so that the regulating range of the regulating valve 5 is larger;

[0038] The regulating head 8 is threadedly connected to the three-way valve body 6. A vent pipe 81 is provided in the regulating head 8. The central axis of the vent pipe 81 is consistent with the central axis of the movable part 74. A spherical protrusion 77 is provided on the side of the expansion platform 76 away from the movable part 74. The spherical protrusion 77 is used to guide the steam flowing through the vent pipe 81 to stabilize the airflow.

[0039] The diameter of the spring 73 is larger than that of the movable part 74. The expansion platform 76 is formed by the movable part 74 extending outward. The diameter of the spring 73 is smaller than that of the expansion platform 76. By setting the expansion platform 76, when the steam pressure fluctuates on the side of the expansion platform 76 away from the movable part 74, the elastic force of the spring 73 automatically adjusts the position of the movable part 74 on the fixed column 75, thereby adjusting the flow blocking effect of the expansion platform 76 on the airflow passing through the vent pipe 81, thereby achieving pressure regulation.

[0040] The movable member 74 is provided with a vent hole 78, the diameter of the movable member 74 is larger than the diameter of the fixed column 75, and the vent hole 78 allows steam to enter between the movable member 74 and the fixed column 75 through the vent hole 78, so that the internal and external pressures of the movable member 74 can be balanced, and the movable member 74 is convenient for self-regulation under the action of the spring 73;

[0041] A gasket 61 is provided between the end cap 71 and the three-way valve body 6. When the end cap 71 is rotated to adjust the position of the threaded member 72 in the three-way valve body 6, the gasket 61 can ensure the air tightness of the three-way valve body 6. A gasket 79 is provided on the outer sleeve of the fixing column 75. The gasket 79 is arranged in the rebound groove 723 to play a buffering effect when the movable member 74 is subjected to a large pressure fluctuation and hits the rebound groove 723.

[0042] The end cap 71 and the outer side of the adjusting head 8 are both provided with a polygonal adjusting ring 82, so as to facilitate the use of tools to adjust the distance between the expansion platform 76 and the end of the adjusting head 8;

[0043] How it works:

[0044] When adjusting the regulating valve 5, the end cap 71 or the adjusting head 8 is rotated, and the threaded member 72 or the adjusting head 8 is rotated along the thread and then moved in the three-way valve body 6, thereby adjusting the distance between the end of the movable member 74 and the end of the adjusting head 8 to achieve pressure regulation. When the steam pressure fluctuation becomes larger, the external pressure of the movable member 74 is relatively large. The movable member 74 is first squeezed by the pressure difference to squeeze the spring 73 and move along the fixed column 75. When the steam enters between the movable member 74 and the fixed column 75 through the vent hole 78, the pressure difference between the inside and outside of the movable member 74 is stabilized, and the movable member 74 is reset under the action of the spring 73 to achieve pressure stability.

[0045] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
