The invention discloses a system and a method for detecting and displaying a status and a fault of an automobile charging system. The method at least comprises the steps of: controlling a first triode to switch on or off a circuit of an indicator lamp by a controller, and enabling the indicator lamp to be on or off long so as to indicate a working status of a power generator; controlling a second triode to switch on or off the circuit of the indicator lamp by the controller, and enabling the indicator lamp to flash so as to indicate an output voltage value of the power generator; and controlling a third triode to switch on a circuit of a buzzer by the controller, and enabling the buzzer to generate an alarm sound so as to indicate that a storage battery is in an insufficient voltage status. As three triodes are adopted, the indicator lamps in the original automobile charging system can be controlled under the control of the controller to respectively indicate the working status and the ...

Dewatering preparation method for high-purity organic matters

Номер: CN102218228A
Автор: Yu Jingfu
Принадлежит:

The invention belongs to the field of organic matter dewatering treatment, particularly relating to a dewatering preparation method for high-purity organic matters. Firstly, water absorbent is adopted for absorbing the water of a target organic matter so as to purify the target organic matter; and a microfiltration film or ultrafiltration film is adopted for separating the water absorbent after absorbing the water and the purified target organic matter so as to obtain the high-purity organic matter. The dewatering preparation method for the high-purity organic matters solves the problem that the current organic matters with higher purity are diffuclt to meet high-purity requirement during dewatering process, in particular to the problem of overhigh energy consumption of the current dewatering method. Meanwhile, the product quality is improved; and the purity of the target organic matter can be stably improved to 99.0-99.9999 percent; meanwhile, the water absorbent can be recycled and used ...

Production process and filtration system of phosphoric acid

Номер: CN103303885A
Автор: Yu Jingfu, Li Songshan, Xiong Bin
Принадлежит:

The invention discloses a production process of phosphoric acid. The production process comprises the following steps of: S1: performing ultrafiltration a coarse phosphoric acid solution to obtain primary filtrate; and S2: performing nanofiltration on the primary filtrate to obtain secondary filtrate and a secondary concentrated solution. The coarse phosphoric acid is treated by ultrafiltration and nanofiltration through the process, so that the yield and purity of the obtained phosphoric acid product are high, and the coarse phosphoric acid is continuously produced by ultrafiltration and nanofiltration to facilitate the continuous production of the process and ensure the operation reliability of the process. The invention further provides a filtration system of phosphoric acid. The filtration system comprises a first charging bucket, an ultrafiltration unit, a nanofiltration unit and a second charging bucket, wherein the input end of the ultrafiltration unit is connected with the output ...

Extraction method of stevioside based on membrane method

Номер: CN102225957A
Автор: Yu Jingfu
Принадлежит:

The invention belongs to the field of stevioside preparation, and in particular relates to an extraction method of stevioside based on a membrane method. The method comprises the following steps: firstly, carrying out rough treatment on stevioside leach liquor so as to obtain a penetrating liquid; filtering the penetrating liquid with a tubular microfiltration membrane or ultrafiltration membrane so as to obtain filtrate; filtering the filtrate with a nanofiltration membrane so as to obtain a concentrated liquid; filtering produced water obtained by nanofiltration membrane filtration excluding the concentrated liquid with a reverse osmosis membrane, reusing the filtered produced water to a stevioside leaching process or a resin absorption process so as to carry out top washing on a resin column, and outwardly discharging after the concentrated liquid obtained by reverse osmosis membrane filtration is qualified by treatment; and finally, filtering the concentrated liquid with the ultrafiltration ...
