Abstract
The utility model discloses a kind of production 2,5-dimethyl-3-hexin-2,5-glycol without in potential safety hazard and still, relate to a kind of chemical production device, in comprising and still body, and be arranged at described in and charging aperture and manhole on still body, on described manhole, be provided with manhole locking device, in described and on still body bottom, be connected with benzene liquid circulating pump, this benzene liquid circulating pump other end is connected with described charging aperture, between described benzene liquid circulating pump and described charging aperture, is provided with sample valve.Compared with the existing, the production 2 of the utility model protection, 5-dimethyl-3-hexin-2,5-glycol without in potential safety hazard and still not from manhole sampling, improved operating environment, removed potential safety hazard.
Description
Technical field
The utility model relates to a kind of chemical production device, particularly a kind of 2,5-dimethyl-3-hexin-2 that produce, 5-glycol without in potential safety hazard and still.
Background technology
Producing 2,5-dimethyl-3-hexin-2, in the process of 5-glycol, relating to and will contain 2,5-dimethyl-3-hexin-2, the benzole soln of 5-glycol carries out acid-base neutralization operation.In existing production process, the manhole place at enamel still in the situation that opening stirring tests pH value.Because the volatility of benzene is stronger, workman's operating condition is extremely severe, and operating environment has also been full of benzene vapour, very easily forms explosive mist, has larger potential safety hazard.And benzene is also larger to workman's health effect.Because the proportion of benzene is light compared with water, in still, be uniformly mixed in process, benzole soln, all the time in liquid level top, often mixes inhomogeneous.Cause workman to operate more difficult.
Utility model content
The purpose of this utility model is just to provide a kind of 2,5-dimethyl-3-hexin-2 that produce, 5-glycol without in potential safety hazard and still, this production 2,5-dimethyl-3-hexin-2,5-glycol without in potential safety hazard and still do not sample from manhole.
The technical solution of the utility model is: a kind of production 2,5-dimethyl-3-hexin-2,5-glycol without in potential safety hazard and still, in comprising and still body, and be arranged at described in and charging aperture and manhole on still body, on described manhole, be provided with manhole locking device, described in and on still body bottom, be connected with benzene liquid circulating pump, this benzene liquid circulating pump other end is connected with described charging aperture, between described benzene liquid circulating pump and described charging aperture, is provided with sample valve.
Compared with prior art, the beneficial effects of the utility model are: the utility model in and still this external installed a circulating pump and will in and still airtight, extract benzole soln in still out iterative cycles from bottom, and a sample valve is installed on pump discharge pipe and has been tested pH value, so, improved operating environment, remove potential safety hazard, ensured that again the stability of operating procedure has reduced the consumption of material.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the utility model one embodiment 1;
Fig. 2 is the overall structure schematic diagram of another embodiment 1 of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, produce 2,5-dimethyl-3-hexin-2,5-glycol without in potential safety hazard and still comprise in and still body 1, and in being arranged at and still body 1 on charging aperture 4 and manhole 2, on manhole 2, be provided with manhole locking device 3, in and still body 1 bottom on be connected with benzene liquid circulating pump 6, these benzene liquid circulating pump 6 other ends are connected with charging aperture 4, between benzene liquid circulating pump 6 and charging aperture 4, are provided with sample valve 5.
Manhole locking device 3 is by removable seal lid and be arranged on the handle that removable seal covers and form.
When production, directly detect pH value by sample valve 5 samplings, thereby prevented overflowing of benzene vapour, improved operating environment, removed potential safety hazard.
Embodiment 2
As shown in Figure 2, produce 2,5-dimethyl-3-hexin-2,5-glycol without in potential safety hazard and still comprise in and still body 1, and in being arranged at and still body 1 on charging aperture 4 and manhole 2, on manhole 2, be provided with manhole locking device 3, in and still body 1 bottom on be connected with benzene liquid circulating pump 6, these benzene liquid circulating pump 6 other ends are connected with charging aperture 4, between benzene liquid circulating pump 6 and charging aperture 4, are provided with sample valve 5.
Between charging aperture 4 and sample valve 5, be provided with benzene liquid measure control device 7, benzene liquid measure control device 7 is provided with feed pipe 8 and drainage conduit 9.
Manhole locking device 3 is by removable seal lid and be arranged on the handle that removable seal covers and form.
When production, the sample analysis result of taking out by sample valve 5, carries out the control of recycle benzene liquid measure, in the time that concentration is excessive, gets rid of a part of benzene liquid measure from drainage conduit 9, when concentration is too low, replenishes fresh benzene liquid measure from feed pipe 8.
Above-mentioned embodiment is only as explanation of the present utility model and unrestricted; the utility model protection domain also should comprise those apparent conversions to those skilled in the art, conversion, variation or substitute; and in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from the utility model aim, make various variations.
