Each stirring reaction still is provided with a feed inlet and a discharge outlet, wherein the feed inlet is located at a position higher than that of the discharge outlet, and an included angle which is 5-15 degrees is formed between a connection line of the feed inlet and the discharge outlet and the horizontal plane. According to the reactor capable of preparing the anhydrous peroxycarboxylic acid continuously, continuous preparation of products is achieved, time for start-up and shutdown needed by batch production is shortened, production efficiency is improved, the technological process is stable and controllable, fluctuation of the technological parameter is small, and quality of the products is stable.
Description
Technical field
The utility model relates to the reactor of the anhydrous peroxycarboxylic acid of a kind of continuous production.
Background technology
The employed reactor of the existing anhydrous peroxycarboxylic acid of preparation is stirred tank, and material from the disposable adding of reactor head, is emitted from reactor bottom after reaction end and the cooling before reaction.Adopt " the thick solution of peroxycarboxylic acid " of this device preparation to finish by batch production, the reactor outlet flow need to be controlled with the control valve group, control valve group place forms between the citadel easily, thereby can cause the decomposition that may cause peroxycarboxylic acid of gathering of peroxycarboxylic acid, when serious even can set off an explosion.In addition, the control valve group control larger fluctuation of liquid level in the device that can induce reaction makes the time of staying produce fluctuation, and then has influence on the composition of outlet material.
The utility model content
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of and enhance productivity, make technical process steadily controlled, technological parameter fluctuation is little, the reactor of the anhydrous peroxycarboxylic acid of continuous production of constant product quality.
The reactor of the anhydrous peroxycarboxylic acid of a kind of continuous production, be composed in series by a plurality of stirred autoclaves with rectifying column, described each stirred autoclave is provided with charging aperture and discharging opening, the discharging opening position of described stirred autoclave is higher than the charging aperture of described adjacent stirred autoclave, and the connecting pipe of the discharging opening of described stirred autoclave and the charging aperture of described adjacent stirred autoclave is horizontal by 5 °～15 ° angle.
In the utility model, the inboard discharging opening of described stirred autoclave place is provided with downflow weir, the overfall of described downflow weir is the discharging opening of described stirred autoclave, and described stirred autoclave is connected with the charging aperture of adjacent stirred autoclave by the overfall of described downflow weir.
In the utility model, described rectifying column is installed on the described stirred autoclave, and the steam port of described stirred autoclave is connected with the import of described rectifying column.
Described a plurality of stirred autoclave is arranged in the shape of a spiral according to the sequencing of reaction.
Adopt said structure, the utlity model has following advantage:
1, the line of described charging aperture and described discharging opening is horizontal by 5 °～15 ° angle, a stirred autoclave after material can successfully flow to from last stirred autoclave like this, and it is residual not have material in the inlet/outlet pipe when stopping, and prevents decomposition or the blast of the peroxycarboxylic acid that causes because of gathering of peroxycarboxylic acid.
2, downflow weir is set and makes level stability in the reactor, need not to use the control valve group so that the stirred autoclave discharging flow can be regulated automatically.
3, adopt this device, can the continuous production product, reduced the required start-stop car time of Batch Process, improved production efficiency, make technical process steadily controlled, technological parameter fluctuation is little, constant product quality.
4, a plurality of stirred autoclaves are arranged in the shape of a spiral according to the sequencing of reaction, can save the area like this, also can each still of series connection be made up flexibly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the reactor of the anhydrous peroxycarboxylic acid of a kind of continuous production in detail.
As shown in Figure 1, the reactor of the anhydrous peroxycarboxylic acid of a kind of continuous production is composed in series by a plurality of stirred autoclaves with rectifying column.Stirred autoclave has chuck to heat or to cool off outward, in have coil pipe also can to heat or cool off, there is perforate the stirred autoclave both sides, be used for charging and discharging, there is downflow weir at the inboard discharging opening of stirred autoclave place, the discharging opening position of described stirred autoclave is higher than the charging aperture of described adjacent stirred autoclave, the connecting pipe of the discharging opening of described stirred autoclave and the charging aperture of described adjacent stirred autoclave is horizontal by 5 °～15 ° angle, a stirred autoclave after material can successfully flow to from last stirred autoclave like this, and it is residual not have material in the inlet/outlet pipe when stopping, and described stirred autoclave comprises the first stirred autoclave 1, the second stirred autoclave 2 and the 3rd stirred autoclave 3.
The inboard discharging opening of stirred autoclave place is provided with downflow weir, the overfall of described downflow weir is the discharging opening of described stirred autoclave, described stirred autoclave is connected with the charging aperture of adjacent stirred autoclave by the overfall of described downflow weir, downflow weir is set makes level stability in the still, avoid the fluctuation of rate of discharge, and rate of discharge does not need to use the control valve group to regulate, when feed rate reduces, liquid level descends in the downflow weir, rate of discharge reduces thereupon, and when feed rate increased, liquid level rose in the downflow weir, rate of discharge increases thereupon, does not need like this control valve group also can stablize liquid level in the control still.
Rectifying column 6 is directly installed on the stirred autoclave, the steam that produces in the stirred autoclave directly enters rectifying column 6, in rectifying column 6, contact with the liquid that refluxes from rectifying column 6 tops, final moisture azeotropic mixture steams from rectifying column 6 tops, in condenser, flow into standing demix in the water knockout drum of rectifying column 6 after the condensation, water flows out from water knockout drum bottom drainpipe 4, and organic solvent is used the pumped back rectifier from water knockout drum top return duct 5.
Concrete preparation process is as follows:
At first, boric acid is dissolved in the carboxylic acid solution that contains organic solvent, continuously send into first stirred autoclave 1 with pump, hydrogen peroxide is also continuously sent into the first stirred autoclave 1 middle part with pump, control the time of staying of material in reactor by the control charging rate, the first stirred autoclave 1 material continues reaction through overfall overflow to the second stirred autoclave 2, pass through again overfall overflow to the three stirred autoclaves 3 of the second stirred autoclave 2, in all stirred autoclaves with steam or hot water heating, and keep and be fluidized state in the stirred autoclave, so that aqueous peroxycarboxylic acid solution's water vapour and organic vapor enter rectifying column 6, in the rectifying column 6 filler is housed, contain organic solvent and water in the rectifying column 6 top distillates, carry out sedimentation separation after the condensation, the water of lower floor is discharged continuously by drainpipe 4, and the organic solvent on upper strata passes through return duct 5 continuous backflow to tower.
