Embodiment Construction
[0016] Such as figure 1 As shown, the bromine drying device includes a tower body 1, and the tower body 1 is provided with a dividing plate 2 that separates the inner cavity of the tower body 1 into an upper packing cavity and a lower material liquid cavity, and a plurality of process tubes are arranged on the dividing plate 2. The liquid hole 3 is provided with a packing layer 4 placed on the partition plate 2 in the packing chamber. The packing layer 4 is composed of packing, and the packing is an existing product, such as Pall ring and Raschig ring, etc. Increase the contact area between concentrated sulfuric acid and bromine to improve the drying efficiency of bromine. The space between the packing layer 4 and the top wall of the tower body 1 is a liquid inlet chamber, and the wall of the liquid inlet chamber is provided with a bromine inlet pipe 5, a concentrated sulfuric acid inlet pipe 6 and an exhaust pipe 7 communicated with the liquid inlet chamber; The bromine inle...

The invention discloses a bromine drying device, comprising a tower body, wherein a separator is arranged in the tower body so as to divide the inner cavity of the tower body into a filler chamber at the upper part and a feed liquid chamber at the lower part; a plurality of liquid via holes are distributed on the separator; a filler layer placed on the separator is arranged in the filler chamber; the space between the filler layer and the top wall of the tower body is a liquid inlet chamber; a bromine inlet pipe, a concentrated sulfuric acid inlet pipe and an exhaust pipe all communicated with the liquid inlet chamber are arranged on the wall of the liquid inlet chamber; a main liquid outlet pipe is connected to the bottom of the tower body; a concentrated sulfuric acid outlet pipe and a bromine outlet pipe are communicated with the main liquid outlet pipe; the concentrated sulfuric acid outlet pipe is connected in series with a concentrated sulfuric acid outflow valve; a first bromine outflow valve and a second bromine outflow valve are orderly connected in series with the bromine outlet pipe; and an overflow branch which is arranged in parallel with the second bromine outflow valve and located above the bromine outlet pipe is connected with the bromine outlet pipe. The device is simple in structure, convenient for use and operation, high in bromine drying efficiency and good in drying effect.
Description
technical field [0001] The invention relates to a bromine drying device. Background technique [0002] Because industrial bromine contains a certain amount of water, this part of water will directly affect the direct application of bromine. In order to reduce or remove the water in bromine, traditional methods often use natural sedimentation for dehydration, that is, use bromine and The specific gravity of water is different, causing bromine to precipitate, so as to achieve the purpose of separating bromine and water. The above-mentioned bromine dehydration method mainly has the following defects, one is low dehydration efficiency, and the other is poor dehydration effect. Therefore, it is necessary to invent a bromine drying device to improve bromine dehydration efficiency and dehydration effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bromine drying device to achieve the purpose of quickly and thoro...
