Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical production, and in particular relates to a device for removing water from by-product steam of a hydrogen chloride synthesis furnace. Background Art
[0002] Currently, most chemical industries use hydrogen chloride for synthetic hydrogen chloride. The main process is that hydrogen and chlorine generated from ion membrane electrolyzers are pressurized and then enter graphite hydrogen chloride synthesis furnaces for combustion. After combustion, hydrogen chloride is generated for use by subsequent devices. During the combustion process of the hydrogen chloride synthesis furnace, the pressure and temperature of the boiler supporting the hydrogen chloride synthesis furnace are reduced, so the by-product steam is unsaturated steam. Lower pressure means that the saturation temperature of the steam is correspondingly lowered. At this time, the steam is more likely to contain liquid water molecules, that is, the dryness of the steam is reduced and the water content is increased.
[0003] Currently, in routine hydrogen chloride synthesis production, water is removed by installing steam traps in steam transmission pipelines, but this is ineffective. The increased water content of the by-product steam reduces its heat transfer efficiency, seriously impacting subsequent production processes. Water droplets produced by steam condensation can impact pipelines and equipment, particularly at valves and elbows, causing water hammer, which can generate significant impact and damage pipelines, valves, and equipment. Furthermore, impurities in the water can accelerate corrosion of pipelines and equipment. Furthermore, when high-water-content steam flows through pipelines, if it encounters low winter temperatures or a sudden valve closure, the water can rapidly condense, creating transient high pressure and generating water hammer, which can lead to pipeline ruptures, equipment damage, and personal injury. Utility Model Content
[0004] The utility model provides a device for removing water from by-product steam of a hydrogen chloride synthesis furnace, so as to solve the problem that the existing drainage method is ineffective and the by-product steam without water removal causes great damage to the equipment.
[0005] The technical solution of the utility model is: a device for removing water from by-product steam of a hydrogen chloride synthesis furnace, comprising a water vapor separator, a vertical baffle being vertically installed at the bottom of the water vapor separator, a by-product steam inlet and a by-product steam outlet being provided on the water vapor separator on both sides of the vertical baffle, a plurality of staggered horizontal baffles being provided on both sides of the vertical baffle, and a drainage pipe being further provided at the bottom of the water vapor separator.
[0006] As a further improvement of the present invention, two drainage pipes are provided, the two drainage pipes are respectively arranged on both sides of the vertical baffle, and pipe sight glasses are installed on the drainage pipes.
[0007] As a further improvement of the present invention, the two drainage pipes are connected to a drainage main pipe, and a drain valve is provided at the end of the drainage main pipe.
[0008] As a further improvement of the present invention, manholes are provided on both sides and the top of the water vapor separator, and cleaning and inspection are carried out through the manholes after long-term operation.
[0009] The beneficial effects of the present invention are as follows: the present invention causes the by-product steam to move in an S-shaped line within the steam separator through cross-arranged baffles. During the movement, the by-product steam encounters the baffles multiple times. Since the suspended water droplets have a large mass and inertia, when they encounter the baffles, the flow direction changes, and the drying steam can bypass the baffles and continue forward, while the water droplets accumulate on the baffles. The by-product steam undergoes processes such as deceleration, collision, direction change, and condensation within the separator, removing the liquid water carried in the steam and achieving the purpose of steam drying. The present invention has a simple structure and high working efficiency, can efficiently achieve the dehydration and drying of the by-product steam, effectively reducing the damage of the by-product steam to the original equipment, and has extremely high promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a schematic structural diagram of the utility model.
[0011] In the figure: 1-steam separator, 2-by-product steam inlet, 3-by-product steam outlet, 4-vertical baffle, 5-drainage pipe, 6-trap, 7-horizontal baffle, 8-manhole, 9-drainage sight glass, 10-triangular bracket, 11-drainage main pipe. DETAILED DESCRIPTION
[0012] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0013] like Figure 1 As shown, a device for removing water from by-product steam of a hydrogen chloride synthesis furnace includes a water vapor separator 1. A vertical baffle 4 is vertically installed at the bottom of the water vapor separator 1. A by-product steam inlet 2 and a by-product steam outlet 3 are provided on the water vapor separator 1 on both sides of the vertical baffle 4. A plurality of staggered horizontal baffles 7 are provided on both sides of the vertical baffle 4. A drainage pipe 5 is also provided at the bottom of the water vapor separator 1. The horizontal baffles 7 are staggered and vertically installed on both sides of the vertical baffle 4 and on the inner wall of the water vapor separator 1.
[0014] There are two drainage pipes 5, which are respectively arranged on both sides of the vertical baffle 4. A pipe sight glass 9 is installed on the drainage pipe 5. The pipe sight glass 9 can help the operator to accurately and timely judge the drainage situation in the steam system under the premise of safety.
[0015] The two drainage pipes 5 are connected to the drainage main 11, and a steam trap 6 is provided at the end of the drainage main 11. The steam trap 6 can stably and timely remove condensed water under high temperature and high pressure, avoid ineffective escape of steam, and improve the overall thermal efficiency of the system.
[0016] Manholes 8 are provided on both sides and the top of the water vapor separator 1, and cleaning and inspection are carried out through the manholes 8 after long-term operation.
[0017] When in use, the water vapor separator 1 needs to be connected to the conveying pipeline of the by-product steam of the hydrogen chloride synthesis furnace first, and the water vapor separator 1 is fixed to the ground by the triangular bracket 10 so that the water vapor separator 1 can be firmly supported during the conveying process. When the hydrogen chloride synthesis furnace is burning, the by-product steam enters the water vapor separator 1 through the by-product steam inlet 2. The steam changes its flow direction many times in the water vapor separator 1. Since the suspended water droplets have a large mass and inertia, when the flow direction changes when encountering the baffle, the dry steam can bypass the baffle and continue to move forward, while the water droplets will accumulate on the vertical baffle 4 and the horizontal baffle 7. The condensed water accumulated on the baffle settles to the bottom of the water vapor separator 1 by gravity, and the water will finally be discharged through the drainage pipes 5 on both sides of the bottom. The steam trap 6 on the drainage pipe 5 can stably and timely remove the condensed water under high temperature and high pressure, while avoiding the ineffective escape of steam, so as to improve the overall thermal efficiency of the steam system.
