Принадлежит:

The invention discloses a high-voltage electric wire fault detecting system based on a CAN bus. The high-voltage electric wire fault detecting system comprises sensors, system slave stations, a control main station and the CAN bus. The sensors are arranged on telegraph poles and nodes, the sensors are connected with the control slave stations, and the control slave stations are connected with the CAN bus. The sensors automatically judge the circuit operation state and accurately locate a fault position, and detection signals are transmitted to the control main station through the CAN bus. The control main station monitors high-voltage electric wires of a whole power grid. The fault detecting system has strong error detection capacity, communication distance is long, and therefore the system is suitable for occasions with strong interference, such as the high-voltage electric wires, time is saved, and work is facilitated.

Purification method of by-product hydrogen chloride of methane chloride

Номер: CN0101935020A
Автор: CHENGJIN WU, YOUPING DENG, LIANG WANG, WU CHENGJIN, DENG YOUPING, WANG LIANG
Принадлежит:

The invention discloses a purification method of by-product hydrogen chloride of methane chloride. In the method, hydrogen chloride gas from a methane chloride device is introduced into a pre-adsorption tower which is filled with adsorbent and a fine desorption tower, and impurities such as chloromethane, water and carbon dioxide are removed, thus obtaining high-purity hydrogen chloride gas which can be used for synthesizing polyvinyl chloride, metal chloride, chlorocarbon or trichlorosilane and the like which have high added value; and the purification method changes the existing process of utilizing the by-product hydrogen chloride of the methane chloride to produce hydrochloric acid with low added value and severe excess production capacity, and the purification method can not only relieve the problem of dull sale of the by-product hydrochloric acid in the original process but also increase the added value of the by-product hydrogen chloride gas, thus obtaining good economic benefit.
