Description

Technical Field

[0001] This utility model relates to the technical field of liquid chlorine unloading filtration devices, and in particular to a liquid chlorine unloading filtration device. Background Technology

[0002] Unloading liquid chlorine involves pressurizing the tanker truck with a compressor and transferring it to the liquid chlorine tank via a liquid phase pipeline. During unloading, impurities from the tanker truck can enter the liquid chlorine tank through the liquid phase pipeline. During operation, these impurities can clog the regulating valves and elbows of the discharge pipeline at the bottom of the liquid chlorine tank, causing insufficient liquid chlorine supply to the chlorination reaction unit. This can be resolved by opening the regulating valves or by restoring the supply after a period of time. When the chlorination reaction unit is started, the precipitated impurities at the bottom of the liquid chlorine tank can cause unstable chlorine pressure in the reaction unit, leading to start-up failure. This also poses safety hazards, and repeated start-ups and shutdowns increase the frequency of these risks, wasting manpower and resources. Utility Model Content

[0006] As a preferred embodiment, the connecting plate is equipped with a handle.

[0007] As a preferred embodiment, the filter barrel is provided with filter mesh holes.

[0008] As a preferred embodiment, the liquid chlorine supply pipeline is connected to the liquid chlorine tank via a liquid chlorine bypass pipeline, and the liquid chlorine bypass pipeline is equipped with a liquid chlorine bypass control valve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The liquid chlorine unloading and filtration device of this utility model filters the liquid chlorine supplied through the liquid chlorine supply pipeline through a liquid chlorine filter before sending it into the liquid chlorine tank. The liquid chlorine filter can filter out impurities in the liquid chlorine, preventing impurities from clogging the liquid chlorine tank. Furthermore, it can prevent unstable chlorine pressure in the reaction unit due to impurities settling at the bottom of the liquid chlorine tank, thus avoiding start-up failure.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0015] A liquid chlorine unloading filtration device includes a liquid chlorine supply pipeline 1, a liquid chlorine filtration branch pipeline 2 connected to the liquid chlorine supply pipeline 1, and a liquid chlorine filter 3 connected to the liquid chlorine filtration branch pipeline 2. The liquid chlorine filter 3 includes a housing 31, an insulation layer 30 on the outer wall of the housing 31, a liquid chlorine inlet 32 ​​on the housing 31, and a filter screen barrel 33 placed inside the housing 31. The top of the filter screen barrel 33 has an inclined opening 34, and an annular connecting plate 35 is provided around the inclined opening 34. The outer wall of the connecting plate 35 is sealed to the inner wall of the housing 31. The liquid chlorine inlet 32... Located at the upper part of the connection between the connecting plate 35 and the outer shell 31, the outer shell 31 has a top cover 36, a nitrogen input pipeline 4 connected to the top cover 36, a nitrogen input valve 5 on the nitrogen input pipeline 4, a vacuum pipeline 6 connected to the top cover 36, a vacuum tank 61 connected to the vacuum tank 61 connected to the vacuum buffer tank 7, a liquid outlet 37 located at the bottom of the outer shell 31, a liquid chlorine filter discharge pipeline 8 connected to the liquid chlorine filter discharge pipeline 8 connected to the liquid chlorine tank 9, and a liquid chlorine filter discharge valve 10 on the liquid chlorine filter discharge pipeline 8.

[0016] Furthermore, a liquid chlorine filter feed valve 21 is provided on the liquid chlorine filter branch line 2.

[0017] Furthermore, a handle 11 is connected to the connecting plate 35.

[0018] Furthermore, the filter barrel 33 is provided with filter mesh holes 12.

[0019] Furthermore, the liquid chlorine supply line 1 is connected to the liquid chlorine tank 9 via a liquid chlorine bypass line 13, and a liquid chlorine bypass control valve 14 is provided on the liquid chlorine bypass line 13.

[0020] During operation, the liquid chlorine unloading filtration device filters the liquid chlorine supplied through the liquid chlorine supply pipeline 1 through the liquid chlorine filter 3 before sending it into the liquid chlorine tank 9. The liquid chlorine filter 3 filters out impurities in the liquid chlorine, preventing them from clogging the liquid chlorine tank 9. It also prevents unstable chlorine pressure in the reaction unit due to impurities settling at the bottom of the liquid chlorine tank, which could lead to start-up failure.

[0021] The handle allows the filter canister 33 to be lifted out for periodic cleaning. When cleaning the liquid chlorine filter 3, because liquid chlorine is toxic and inhalation can harm the human body, the liquid chlorine inside the filter 3 must be completely drained before cleaning. This is done by opening the nitrogen inlet valve 5, allowing nitrogen to enter the liquid chlorine filter 3 through the nitrogen inlet line 4, replacing the liquid chlorine inside. After replacement, the vacuum line 6 is opened, creating a negative pressure environment inside the liquid chlorine filter 3, allowing nitrogen to circulate and purge impurities from the filter 3.

[0022] The specific implementation of this utility model has been described in detail above, but it is only an example. This utility model is not limited to the specific implementation cases described above, and equivalent modifications to this utility model are also within the protection scope of this utility model.
