Embodiment Construction

[0026] The present invention will be further described below using the accompanying drawings and examples.

[0027] refer to figure 1 , The high-efficiency falling film evaporation reboiler of the present invention includes a cylinder body 3, and a support 5 is fixedly connected to the middle of the cylinder body 3, and the high-efficiency falling film evaporation reboiler is installed on a position of a set height through the support 5. A steam inlet d and a vent opening f are arranged on the upper part of the cylinder body 3, and a steam outlet e and a clean outlet g are arranged on the lower part of the cylinder body 3. The vent port f is used to vent the internal gas before the test run, and the drain port g is used to drain the internal liquid after parking. The lower end of the cylinder body 3 is fixedly connected with the lower cover plate 19, and the lower cover plate 19 is provided with a lower head 2, and a lower connection pipe 1 is fixedly connected in the lower h...

Abstract

The invention relates to a high-efficiency falling film evaporation reboiler which is characterized by comprising a cylinder body, wherein at least two porous evaporating and reboiling block bodies, a distributing cone, a thin-film evaporating and absorbing lower single block, at least one thin-film evaporating and absorbing middle single block, a thin-film evaporating and absorbing upper single block, a gas-liquid distributing disk and a gas-liquid mixing chamber are sequentially arranged in the cylinder body from bottom to top in an accumulating way, the gas-liquid distributing disk is fixedly connected with a plurality of absorbing weirs communicated with the gas-liquid mixing chamber, the upper part of the gas-liquid mixing chamber is provided with a defogger, and the top end of the gas-liquid mixing chamber is fixedly connected with an upper cover plate by a graphite cover plate. The Hcl and the C2H5OH of the mixed liquid material of isobutyric acid, the Hcl and triethyl phosphate can be removed by the heat exchange of steam so as to separate out a finished product of the triethyl phosphate. The high-efficiency falling film evaporation reboiler has the advantages of reasonable structure, low height, small floor area, low cost, high separation efficiency, good effect, energy saving, the environmental friendliness, simpleness for operation, low working pressure, high safety performance and the like.

Description

technical field [0001] The invention relates to an alcohol and hydrogen chloride separation device, which is a high-efficiency falling film evaporation reboiler. Background technique [0002] Existing alcohol and hydrogen chloride separation devices, one is to use a glass-lined reactor, graphite condenser, distillation tower, vacuum pump, etc. to heat the materials in the reactor, the alcohol will be heated and gasified, and hydrogen chloride will be released at the same time, and enter the condenser to condense. The device has small production capacity, high energy consumption, high cost, and the material stays in the high-temperature gasification zone for a long time, and the leaked gas is flammable and explosive. The acid-containing gas stays in the high-temperature zone for a long time, which will cause high damage to the equipment and low service life of the equipment. , there is a security risk. The second is to adopt the tower type dealcoholization and deacidificatio...
