[0002] Hydrochloric acid synthesis is usually carried out in a flash tank. High-pressure, high-temperature fluid enters the flash tank, and after expansion, the pressure decreases. The fluid boils and vaporizes rapidly in the flash tank, and the vapor and liquid phases are separated.

[0003] A flash evaporator (CN203483896U) is provided, comprising a tank body, a feed inlet, a liquid phase outlet, a gas phase outlet, and a support located at the bottom of the tank body. A homogenization device is provided at the lower part of the tank body. Its advantage is that by setting a homogenization device consisting of a first baffle and a second baffle in the tank body, the liquid phase entering from the feed inlet overflows from the first baffle to the surface of the second baffle. Since the second baffle is a horizontal rectangular plate structure with its two sides connected to the inner wall of the tank body, the liquid phase overflowing to the surface of the second baffle can spread rapidly, expand the evaporation area, accelerate the evaporation rate, improve flash evaporation efficiency, and improve flash evaporation quality.

[0004] However, the steam from the aforementioned utility model is directly emitted after processing, and the gas contains a small amount of acidic substances, which is not conducive to environmental protection. Utility Model Content

[0005] The purpose of this invention is to provide a steam flash evaporation tank, which aims to solve the problem that existing devices directly discharge steam after processing, resulting in the presence of a small amount of acidic substances in the gas, which is detrimental to environmental protection.

Figure 3 This is a cross-sectional schematic diagram of a steam flash evaporation tank according to the present invention.

[0021] This utility model provides a steam flash evaporation tank, comprising a flash tank body 101 and a steam recovery assembly 102. The steam recovery assembly 102 includes a connecting pipe 103, a tank body 104, a branch pipe 105, a spiral pipe 106, a collecting pipe 107, a water inlet pipe 108, a water outlet component 109, a water outlet pipe 110, a first control valve 111, a second control valve 112, a temperature monitor 113, a collection box 114, an observation window 115, rollers 116, and a corrugated pipe 117. This solution solves the problem of existing devices directly emitting steam after processing, resulting in the steam containing a small amount of acidic substances, which is detrimental to environmental protection.

[0022] In this embodiment, the connecting pipe 103 is connected to the flash tank body 101 and located on one side of the flash tank. The tank body 104 is installed at the end of the connecting pipe 103 away from the flash tank body 101. The diverter pipe 105 is fixedly connected to the tank body 104 and located at the top of the tank body 104. The collector pipe 107 is fixedly installed at the bottom of the tank body 104. The spiral pipe 106 communicates with the diverter pipe 105 and the collector pipe 107, and is located between the diverter pipe 105 and the collector pipe 107. The inlet pipe 108 is installed at the top of the tank body 104. The outlet component 109 is connected to the tank body 104 and located on the outside of the tank body 104. The flash tank body 101 is used for hydrochloric acid synthesis processing. The steam generated during processing is discharged through the steam outlet of the flash tank body 101 and enters the tank body 104 through the connecting pipe 103. The diversion pipe 105 on the tank body 104 divides the steam into multiple groups that enter the spiral tube 106. Water is injected into the tank body 104 through the water inlet pipe 108. The injected water absorbs the heat generated by the spiral tube 106. The water that absorbs heat and heats up is discharged through the water outlet component 109 for subsequent use. The steam in the spiral tube 106 is cooled and liquefied, and enters the collector pipe 107 for centralized discharge. This solves the problem that existing devices directly discharge steam after processing, and the steam contains a small amount of acidic substances, which is not conducive to environmental protection.

[0023] The water outlet component 109 includes a water outlet pipe 110 and a first control valve 111. The water outlet pipe 110 is connected to the tank 104 and is located on one side of the tank 104. The first control valve 111 is connected to the water outlet pipe 110 and is located on one side of the water outlet pipe 110. The water outlet pipe 110 is used to discharge water from inside the tank 104. The opening and closing of the water outlet pipe 110 is controlled by the first control valve 111.

[0024] Secondly, the steam recovery assembly 102 also includes a second control valve 112 and a temperature monitor 113. The second control valve 112 is connected to the manifold 107 and is located on one side of the manifold 107. The temperature monitor 113 is connected to the tank 104 and is located on the top of the tank 104. The second control valve 112 can control the opening and closing of the manifold 107, thereby controlling the amount of liquid discharged. The temperature monitor 113 is used to monitor the water temperature inside the tank 104 to facilitate the control of drainage and water injection.

[0025] Furthermore, the steam recovery assembly 102 also includes a collection box 114 and an observation window 115. The collection box is located at the bottom of the manifold 107, and the observation window 115 is fixedly connected to the collection box 114 and located on one side of the collection box 114. The collection box 114 is used to collect the liquid discharged from the manifold 107, so as to facilitate the collection of liquid for subsequent processing. The observation window 115 is used to observe the amount of liquid in the collection box 114.

[0026] Finally, the steam recovery assembly 102 also includes a roller 116 and a bellows 117. The bellows 117 is connected to the collection box 114 and is slidably connected to the manifold 107, and is located on one side of the collection box 114. The roller 116 is rotatably connected to the collection box 114 and is located at the bottom of the collection box 114. The roller 116 reduces the friction between the collection box 114 and the placement surface, making it easier to move the collection box 114. The bellows 117 is connected to the manifold 107 via the collection box 114 to prevent liquid splashing.

[0027] In the use of a steam flash evaporator of this utility model, the flash evaporator body 101 is used for hydrochloric acid synthesis processing. The steam generated during processing is discharged through the steam outlet of the flash evaporator body 101 and enters the tank body 104 through the connecting pipe 103. The diverting pipe 105 on the tank body 104 divides the steam into multiple groups that enter the spiral tube 106. Water is injected into the tank body 104 through the water inlet pipe 108. The injected water absorbs the heat generated by the spiral tube 106. The water that absorbs heat and heats up is discharged through the water outlet component 109 for subsequent use. The steam in the spiral tube 106 is cooled and liquefied, and enters the manifold 107 for centralized discharge. This solves the problem that existing devices directly discharge steam after processing, and the steam contains a small amount of acidic substances, which is not conducive to environmental protection.

[0028] The above description is merely a preferred embodiment of the steam flash evaporation vessel of this utility model, and should not be construed as limiting the scope of the utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this utility model are still within the scope of the utility model.
