Description
Technical field
The utility model relates to produce AKD technical field, in particular to a kind of exhaust system for AKD washing process.
Background technique
AKD (alkyl ketene dimer) is to react to obtain by fat acyl chloride and excessive triethylamine, while generating AKD
By-product triethylamine hydrochloride generally uses in industrial production to remove the triethylamine hydrochloride of excessive triethylamine and by-product
Dilute hydrochloric acid washing, system is divided into the more similar two-phase of appearance, i.e. upper organic phase AKD gas producing formation and lower layer's ammonium salt water after washing
Solution, lower layer's ammonium salt aqueous solution to be discharged, upper layer AKD carry out subsequent washing process again.
Currently, workshop row's ammonium salt aqueous solution is by manual operation, operator observes two-phase interface by glass mirror, leads to
Cross the valve that row's ammonium salt solution is closed in manual operation.Because two-phase appearance is similar, interface difficult judgment, it is easy to judgement occur and lose
Accidentally, causing AKD to drain into ammonium salt water causes AKD to lose or ammonium salt water is not clean influences subsequent processing, causes under AKD quality
Drop；In addition, this mode of operation, occupies manually, worker's heavy workload, time-consuming.
Therefore, it is necessary to it is a kind of be able to solve heavy workload existing for current manual separation, interface is difficult to the problems such as judging
System.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts, providing one kind can be realized two-phase interface
Accuracy of judgement prevents from AKD from misprinting causing product to lose and ammonium salt water does not drain influences product quality and improve AKD finished product and obtain
Rate and the exhaust system for AKD washing process for reducing worker's workload, improving production efficiency.
To achieve the goals above, the exhaust system for AKD washing process of the utility model has following constitute:
The exhaust system includes main discharge pipe, and the one end of the main discharge pipe is arranged with the first branch respectively
It puts pipeline and second branch's discharge pipe is connected, the main discharge pipe is provided with electric conductivity detector, and described first
Branch's discharge pipe is provided with the first pneumatic operated valve, and second branch's discharge pipe is provided with the second pneumatic operated valve, the electricity
Conductance detector is connected with first pneumatic operated valve and the second pneumatic operated valve, the knot detected according to the electric conductivity detector
The closing of existing first pneumatic operated valve of fruit and the opening of the second pneumatic operated valve.
Preferably, having pre-determined distance between the electric conductivity detector and the first pneumatic operated valve or the second pneumatic operated valve, use
In reduction loss of material.
Preferably, the other end of the main discharge pipe is connected with the discharge gate of AKD washing kettle.
Preferably, first branch's discharge pipe is the pipeline for discharging ammonium salt solution, second branch
Discharge pipe is the pipeline for discharging AKD.
Using the exhaust system for AKD washing process of the utility model, in washing kettle discharge, the row's of opening ammonium salt is molten
The valve of liquid detects material conductivity value by online electric conductivity detector, shows ammonium salt solution when conductivity changes
It is drained, the valve of the row's of closing ammonium salt solution, and the valve of the row of opening AKD carries out draw operation, two-phase interface accuracy of judgement prevents
AKD, which is misprinted, causes product loss and ammonium salt water not to drain influence product quality, and improves AKD finished product yield；Electricity can be used
Brain control is reduced worker's workload, is improved production efficiency with automatic operation.
