Description
Technical field
The utility model is related to chemical production device technical field, the process units of specifically a kind of orthanilic acid.
Background technology
Orthanilic acid, also known as 2- aminobenzenesulfonic acids, can be dissolved in concentrated hydrochloric acid, be slightly soluble in water, not dissolve in ethyl alcohol and ether.
It is a kind of important reactive dye intermediate, is widely used in reactive brilliant red K-2B, bright red K-2BP, bright red K-2G, bright red M-
2B, bright red X-B, bright red X-10B, active purple k-3r etc..
The technique of traditional mode of production orthanilic acid can be expressed as, using ortho-nitrochlorobenzene as predominant starting material, through several
Chemical conversion is walked, synthesizes o-nitrobenzene sulfonic acid or ortho-nitrophenyl sulfonic acid chloride, then in acid condition, using iron powder reducing method handle
O-nitrobenzene sulfonic acid or ortho-nitrophenyl sulfonic acid chloride are converted into orthanilic acid, and reaction terminates, and cooling, crystallization is separated by solid-liquid separation, i.e.,
Orthanilic acid product can be obtained.As iron powder reducing method is put into the disabling synthesis technology ranks that ban to approve, there is advanced environmental protection
The catalytic hydrogenating reduction method of property is used in the building-up process of orthanilic acid, since catalytic hydrogenating reduction method is in PH=6 ~ 8
It is carried out in range, therefore, catalytic hydrogenating reduction reaction terminates, and material need to be after acid out, cooling, crystallization, separation of solid and liquid etc.
Reason process can just obtain orthanilic acid.Existing acid out device is carried out in conventional tank reactor, and artificial detection is passed through
The acidity of material in kettle, hydrochloric acid dosage is significantly exceeded in acidization, cause orthanilic acid yield is high, at acid waste water
Reason amount is big.
Utility model content
Utility model aims to solve the problems mentioned above in the background art, provide a kind of orthanilic acid
Process units.
A kind of process units of orthanilic acid described in the utility model includes two connected by pipeline, valve
Combined into one apparatus and DCS control devices, the two-in-one device include the built-in two-in-one tank for being rotatable through filter plate, frequency conversion stirring
Device, filtrate collecting tank, orthanilic acid collecting tank；The DCS control devices include hydrochloric acid tank, flowmeter, automatically cut off
Valve, DCS system, the thermometer being installed on inside two-in-one tank, the PH being installed on inside two-in-one tank meters.
Further, the built-in filter plate that is rotatable through is porous plate, and 300 ~ 400 mesh of aperture, material is resistance to hydrochloric acid material.
Further, the frequency conversion blender agitating paddle bottom and the built-in spacing for being rotatable through filter plate about 2cm.
Further, automatic packaging machine is equipped in the orthanilic acid collecting tank.
Further, the two-in-one tank is jacket canister.
The advantages of the utility model and generation good effect are：By to sour in existing orthanilic acid production process
The device upgrade for analysing process has achieved the purpose that reduce hydrochloric acid dosage, has reduced artificial and spent acidic water, and orthanilic acid is received
Rate improves five percentage points, meanwhile, reduce acid waste water processing pressure.
