Neutralization treatment device for nitrocellulose waste acid water and lime cream

The invention discloses a neutralization treatment device for nitrocellulose waste acid water and lime cream and relates to the field of wastewater treatment. The neutralization treatment device for the nitrocellulose waste acid water and the lime cream can stably control the neutralization pH value of the waste acid water and the lime cream and reduce failure rate of lime cream valves and comprises a neutralization reaction tank, a lime cream storage trough, lime cream pipelines, an acid water pipeline, controllers, a lime cream return pipeline and a pH value sensor of the neutralization reaction tank, wherein the acid water pipeline is connected with the neutralization reaction tank; an acid water pump is arranged on the acid water pipeline; two ends of the lime cream pipeline are connected with the lime cream storage trough and the neutralization reaction tank; a lime cream pump, a three-way connector and a lime cream valve with the fixed opening degree are sequentially arranged on the lime cream pipelines; two ends of the lime cream return pipeline are respectively connected with the lime cream storage trough and the three-way connector; the controllers control the rotational speed of the acid water pump according to the signals of the pH value sensor. The neutralization treatment device for the nitrocellulose waste acid water and the lime cream can be used for the design of neutralizing treatment devices for nitrocellulose waste acid water and the lime cream and reconstruction of conventional devices.
