The equipment achieves the purpose of separation by utilizing the temperature difference between the upper part and the lower part in the stripping tower and the dissolution characteristics of carbon dioxide gas and amine in the solvent in water. Effectively ensuring the smooth proceeding of the subsequent dechlorination step. The solvent treatment capacity and the mass transfer efficiency are improved, and the operation performance of equipment is ensured.
Description
Technical field
The utility model belongs to environmental technology field, relates in particular to a kind of cleaning by solvent equipment.
Background technology
In the deep processing industries such as chemical industry, food, medicine, leather manufacture, metallurgy, one of the raw material that is absolutely necessary such as water, organic and inorganic solvent.Especially at some, raw material are required in stricter industry, while containing the impurity such as chlorine, carbon dioxide, amine, hydrogen chloride, aliphatic acid, oils if produce in water used, various other solvents, the as easy as rolling off a log quality of finished that affects, and long-term use also easily causes the corrosion of metallic conduit and equipment containing corrosive material.Therefore these raw materials must be through removing the impurity such as acid, chlorine, ammonia before using.And existing solvent pre-treatment equipment exists, said components removal efficiency is low, production is difficult to the problems such as use standard up to standard with solvent.
The reason that causes the problems referred to above be mainly due to: after existing solvent pre-treatment equipment generally adopts chemical-process that the amine in solvent, sour gas and chlorine are removed, then carry out biochemical treatment.Chemical-process has moved use for many years, and technology is more stable, but after solution depickling is processed, most of carbon dioxide in solvent is removed, make follow-up system pH meta-alkalescence, this will affect the removal effect of dechlorination system, can not reduce to greatest extent the content of raw material with chlorine in solvent.Therefore removing after sour gas and amine, ensure that as far as possible dechlorination system is in desirable pH value scope, the disposal ability that improves dechlorination depickling deamination equipment has just become existing technology urgent problem with mass-transfer efficiency.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of disposal ability and the de-amine equipment of mass-transfer efficiency is high, operating characteristics is good combined type solvent depickling dechlorination.
For achieving the above object, technical solution adopted in the utility model is:
A kind of solvent Combined pressurization depickling dechlorination deamination equipment, it is characterized in that comprising stripper, flash tank group and dechlorination tank, described stripper, flash tank group and dechlorination tank three connect to form a closed circuit by pipeline, stripper is also provided with condensation vapor outlet, colvent inlet, steam inlet and solvent outlet from top to bottom successively, described flash tank group is made up of the one-level flash tank being connected in series, two-stage flash tank and three grades of flash tanks, three grades of flash tank tops are connected with Ammonia collector, and below is connected with dechlorination tank.
Described stripper is up-thin-low-thick cylindrical structure, is provided with the column plate that quantity is no less than 2 in tower.
Described one-level flash tank, two-stage flash tank and three grades of flash tank internal pressures become gradient to increase.
In described dechlorination tank, be provided with water, hypochlorite or active carbon.
The beneficial effects of the utility model are: the upper and lower temperature difference in equipment utilization stripper that the utility model provides, and carbon dioxide and the dissolution characteristics of ammonia in water in solvent, reach the object of separation.Carbon dioxide is removed by air lift to tower top, and the ammonia containing in solvent is discharged through the effect of three grades of flash tank groups by circulation branch road, effectively reduces thus the pH value of deacidification except solvent after ammonia, thereby is conducive to carrying out smoothly of follow-up dechlorination step.Improve solvent disposal ability and mass-transfer efficiency, ensured the operating characteristics of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-stripper, 2-flash tank group, 3-dechlorination tank, 4-pipeline, 5-condensation vapor outlet, 6-raw material colvent inlet, 7-steam inlet, 8-solvent outlet, 9-one-level flash tank, 10-two-stage flash tank, tri-grades of flash tanks of 11-, 12-amine collector, 3-column plate.
Detailed description of the invention
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples and be described with reference to the accompanying drawings as follows:
The de-amine equipment of a kind of combined type solvent depickling dechlorination, comprise stripper 1, flash tank group 2 and dechlorination tank 3, stripper 1, flash tank group 2 and dechlorination tank 3 threes connect to form a closed circuit by pipeline 4, stripper 1 is also provided with condensation vapor outlet 5, raw material colvent inlet 6, steam inlet 7 and solvent outlet 8 from top to bottom successively, flash tank group 2 is made up of the one-level flash tank 9 being connected in series, two-stage flash tank 10 and three grades of flash tanks 11, three grades of flash tank 11 tops are connected with Ammonia collector 12, and below is connected with dechlorination tank 3; Wherein stripper 1 is up-thin-low-thick cylindrical structure, is provided with the column plate 3 that quantity is no less than 2 in tower, and one-level flash tank 9, two-stage flash tank 10 and three grades of flash tank 11 internal pressures become gradient to increase, and are also provided with water, hypochlorite or active carbon in dechlorination tank 3.
Operating principle of the present utility model is: the utility model utilizes the upper and lower temperature difference in stripper, and sour gas and the dissolution characteristics of amine in water in medium, reaches the object of separation.Under certain pressure and temperature, the relative volatility of carbon dioxide is greater than the relative volatility of amine, and the solubility of amine is far longer than the solubility of carbon dioxide, the condensed water that therefore stripper jacking enters makes most water vapours and amine proceed to liquid phase and flows to current downflow with liquid.Carbon dioxide mass fraction increases finally gradually to be removed by air lift to tower top.The amine of liquid phase enters through circulation branch road the amine that the further condensation simmer down to of flash tank group mass fraction is greater than 99%.The solvent of removing sour gas and amine removes dechlorination through dechlorination tank, is back in stripper and finally and discharges and remove.
Above detailed description of the invention of the present utility model is had been described in detail, but described content is only preferred embodiments of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
