Abstract
The utility model discloses a chlorination liquid discharge system for production of chloroactic acid. The chlorination liquid discharge system comprises a chlorination kettle and crystallization kettles, as well as an intermediate storage tank, wherein an outlet of the chlorination kettle is connected with an inlet of the intermediate storage tank, the intermediate storage tank is provided with a low liquid level outlet and a high liquid level outlet, and the low liquid level outlet and the high liquid level outlet are respectively communicated with the crystallization kettles. The chlorination liquid discharge system disclosed by the utility model has the advantages that chlorination liquid in the chlorination kettle is firstly discharged into the intermediate storage tank, and the chlorination liquid is respectively pressed into the two crystallization kettles at twice according to the liquid level so as to facilitate the control of discharge and pressing processes of the chloroactic acid chlorination liquid, greatly reduce the retention time of the chlorination liquid in the chlorination kettle, improve the utilization rate and the chlorination yield of the chlorination kettle, effectively improve the economic benefits of a chloroactic acid device, reduce the risk of being in compression of the chlorination kettle and improve the safety in production of the chloroactic acid.
Description
Technical field
The utility model relates to a kind of chlorated liquid material drain system of production of chloroacetic acid.
Background technology
In existing monoxone device production process, chlorated liquid directly is pressed into crystallisation by cooling in crystallization kettle by chlorination tank.Due to corresponding two crystallization kettles of the difference of the chlorated liquid in a chlorination tank,, for two crystallization kettles, there is long problem of binder time in a still chlorated liquid, and and high to the chlorination tank requirement of withstand voltage.When two crystallization kettles only have one when idle, that still chlorated liquid will have 50% to be pressed into this idle crystallization kettle, and the residue chlorated liquid will be waited for the another crystallization kettle free time.Chlorated liquid time of staying in chlorination tank is long, causes the chlorination tank utilization rate low, and the chlorination tank pressurized is prone to leak source, affects the normal production of monoxone and chlorination tank utilization rate.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model is to provide a kind of chlorated liquid material drain system of production of chloroacetic acid, shortens the time of staying of chlorated liquid in chlorination tank, improves chlorination tank utilization rate and output, reduces the pressurized risk of chlorination tank.
Technical scheme: a kind of chlorated liquid material drain system of production of chloroacetic acid, comprise chlorination tank, crystallization kettle, also comprise intermediate storage tank, described chlorination tank outlet is connected with the import of described intermediate storage tank, described intermediate storage tank arranges low liquid level outlet and the outlet of high liquid level, and described low liquid level outlet and described high liquid level outlet are communicated with a described crystallization kettle respectively.
The corrosion resistant enamel structure that described intermediate storage tank is the jacketed insulation.
The air pressure mouth is set on described intermediate storage tank, by access nitrogen, chlorated liquid is pressed into to crystallization kettle.
Beneficial effect: compared with prior art, the utility model has the advantages that the chlorated liquid in chlorination tank is first put into to intermediate storage tank, at twice chlorated liquid is pressed into respectively to two crystallization kettles by intermediate storage tank according to liquid level, in order to control the blowing of monoxone chlorated liquid and the process of binder, greatly shortened the time of staying of chlorated liquid in chlorination tank, improve chlorination tank utilization rate and chlorination output, effectively improved the economic benefit of monoxone device, reduce the pressurized risk of chlorination tank, improve the security of production of chloroacetic acid.
The accompanying drawing explanation
Accompanying drawing is the utility model system architecture schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, a kind of chlorated liquid material drain system of production of chloroacetic acid, comprise chlorination tank 1, crystallization kettle 2, intermediate storage tank 3, import 5, air pressure mouth 8 and low liquid level outlet 6, high liquid level outlet 7 are set on intermediate storage tank 3, chlorination tank 1 outlet 4 is connected with import 5, low liquid level outlet 6 and high liquid level outlet 7 are communicated with a crystallization kettle 2 respectively, and air pressure mouth 8 is connected into nitrogen.
Chlorated liquid in chlorination tank 1 is first directly put into intermediate storage tank 3, and chlorated liquid is pressed into two crystallization kettles by nitrogen at twice because the height of liquid level is different in intermediate storage tank 3.
Intermediate storage tank 3 is the corrosion resistant enamel structure of jacketed insulation, and the import 5 on it, air pressure mouth 8 and low liquid level outlet 6, high liquid level outlet 7 adopt four fluorine tube to connect.
