Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of toluene dehydrating agent recycling system, as depicted in figs. 1 and 2, it includes reactor 1, installed in reactor 1
On destilling tower 2, the condenser 3 connected with destilling tower 2 and the storage tank 5 for being stored the liquid after cooling.In storage
Return duct 4 is set between tank 5 and reactor 1, the upper toluene after being stood by storage tank 5 is back flowed into reactor
It is dehydrated again in 1.Reactor 1 is passed through steam and heated, and it is fierce that reaction is carried out, and to the toluene in reactor 1 with
And water is heated, it is converted into gaseous state, discharged gaseous mixture by destilling tower 2.Condenser 3 is entered to be condensed
Stood afterwards being drained into storage tank 5, allow toluene to be separated from water and be layered.By setting adjutage in the bottom of storage tank 5
53, and discharging valve 54 is installed on adjutage 53, lower floor's water is released.
As depicted in figs. 1 and 2, the problem of many times can be due to liquid level, there is portion in the derived toluene in storage tank 5
Point water enters return duct 4, in order to prevent water from entering reactor 1 along return duct 4, is inlet segment 41 by 4 points of return duct, dams
Section 42 and reflux section 43, are set by the concave shape tubular construction for section 42 of damming, allow water to stay in bend position, and then reach into one
Walk the purpose that intercept is carried out to water.General section 42 of damming includes descender and ascending part, so that concave configuration is formed, and then can
Water is carried out by therefore, section of damming 42 can be arranged to S types structure, U-shape structure or V-structure.The upper end of section of damming 42
Position is concordant with horizontal segment or less than horizontal segment, and this set can facilitate liquid to enter to dam in section 42.Reflux section 43
It is concordant with the top position of section 42 of damming or less than the top position set.It is this dehydrating agent to be allowed to be efficiently entering reflux section
43, and be flowed into reactor 1.
As depicted in figs. 1 and 2, storage tank 5 primarily to stratification and set, and fallen down in condenser 3
Condensed fluid can cause water level fluctuation, so as to be impacted to the liquid level of standing, and then influence layered effect, can enter during backflow
Compare many water, be unfavorable for recycling.As shown in figure 3, in order to solve the problem, air deflector is set in the tank mouth of storage tank 5
6, liquid is imported into by the inwall of storage tank 5 by air deflector 6, so as to allow liquid to be flowed down along inwall, by inwall to liquid
Attraction, slow down flowing velocity, and then liquid is entered storage tank 5 and will not be produced influence to the liquid level of standing.Air deflector 6 is wrapped
The mounting sleeve 61 for being wholely set and being connected with condenser 3 with storage tank 5 and the interior axle 62 in mounting sleeve 61 are included,
Set some connecting rods 63 to connect between interior axle 62 and mounting sleeve 61, in interior axle 62 connect flow deflector 64, flow deflector 64 it is straight
Footpath conversion mutually waited until with inwall to fitting from interior axle 62, and left gap 65 and slid for liquid.
As depicted in figs. 1 and 2, section of damming 42 has the effect intercepted water, so that, water can be accumulated in the position of section 42 of damming, and
After section of damming 42 intercepts water excessively, it can overflow, so that water can enter reactor 1.In order to avoid the generation of this problem,
The bottom of section of damming 42 sets drainpipe 44, while being provided with draining valve 45 on drainpipe 44.Dilutional hyponatremia in storage tank 5 surpasses
The position of inlet segment 41 is crossed, now, the moisture content that inlet segment 41 enters can cause water to enter reactor 1 than larger.For
This problem is solved, water intaking valve 46 is set on inlet segment 41, the setting of water intaking valve 46 can be prevented in draining or when depositing
Water in storage tank 5 it is too high and enter return duct 4 the occurrence of.
As shown in figure 1, in order to check whether the liquid level of the liquid in storage tank 5 exceedes the position of inlet segment 41, in storage
The outside of tank 5 is provided with liquid level tube 51.The water level observed by liquid level tube 51 in storage tank 5, so as to judge the water in return duct 4
It is whether excessive.Liquid level tube 51 is usually glass structure, thus is easily crashed, and liquid level tube 51 is protected, in liquid level tube 51
Outer rim is provided with guard rail 52.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
