[0002] The main process for removing ammonia from coal gas is to use sulfuric acid to react in a spray saturator to generate ammonium sulfate. Coal gas contains a large amount of organic matter, collectively referred to as tar. After removing most of the large molecular tar and tar residue in front of the coal gas blower, there are still organic matter with larger molecular weights that are sent to the subsequent process section with the coal gas. The tar in the coal gas will react with the sulfuric acid in the saturator to generate acid tar. The full flow tank is a device used in the ammonium sulfate section of the coking industry to remove acid tar from the spray saturator, ensure the quality of sulfuric acid in the saturator, and regularly add sulfuric acid to the full flow tank to ensure the acidity in the saturator.

[0003] The structure of the existing full flow trough is as follows Figure 1 As shown in the figure, its liquid seal area occupies part of the middle area of ​​the box. Figure 1 As shown in the figure, since the liquid seal area is set narrowly and the mother liquid flows into the full flow slot at a high speed, the mother liquid will surge, resulting in the inability to form an effective liquid seal in the liquid seal area, which will lead to gas leakage. Gas leakage will cause product loss, resulting in economic losses; it will cause environmental pollution, so it is necessary to effectively solve the gas leakage problem. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
