A system and method for separating aluminum trichloride from cold-hydrogenated silicon tetrachloride includes a pressure-reducing tank, a condenser, a first extraction tank, a second extraction tank, a clear liquid filter, and a clear liquid tank. The system is characterized by: a silicon tetrachloride inlet pipe at the top of the pressure-reducing tank; the bottom of the pressure-reducing tank being connected to the first and second extraction tanks via pipes; the bottoms of the first and second extraction tanks being connected to a dryer via pipes; the side walls of the first and second extraction tanks being connected to the clear liquid filter via pipes; the tops of the first and second extraction tanks being connected to the condenser via pipes; the bottom of the condenser having a liquid outlet pipe connected to the top of the clear liquid tank; and the bottom of the clear liquid tank having a silicon tetrachloride recovery pipe; and the clear liquid filter being connected to the liquid outlet pipe via a pipe. This invention improves the clogging situation of the entire cold hydrogenation system, solves the problem of long-term operation of the cold hydrogenation system, and reduces the equipment failure rate.

This utility model belongs to the technical field of filtration equipment and discloses a crude oil impurity filtration device. This crude oil impurity filtration device includes a receiving cylinder, a sleeve, a filtration mechanism, and a drain pipe. The receiving cylinder has a receiving cavity, including an oil inlet and an oil outlet. The sleeve is fixed inside the receiving cavity to divide it into a first chamber and a second chamber. The oil inlet communicates with the first chamber, and the oil outlet communicates with the second chamber. The filtration mechanism includes a filter cartridge assembly and a rotating assembly. The filter cartridge assembly is located inside the second chamber and is fixedly connected to the sleeve. The filter cartridge assembly has multiple circumferential filter holes and an opening at its top that communicates with the first chamber. The rotating assembly is rotatably disposed inside the filter cartridge assembly and includes several spirally distributed helical blades. One end of the drain pipe is connected to the bottom end of the filter cartridge assembly, and the other end extends outside the receiving cylinder. This crude oil impurity filtration device has low maintenance costs and high filtration efficiency.

The utility model relates to multi-stage filtering equipment for alkane production, which comprises a vertical filtering tank and is technically characterized in that an air inlet vertical pipe communicated with an air inlet is arranged in the center of the vertical filtering tank, the lower end of the air inlet vertical pipe extends to the bottom of the vertical filtering tank, and a rotatable sleeve is arranged on the outer side of the air inlet vertical pipe. A first-stage filtering assembly, a second-stage filtering assembly and a third-stage filtering assembly are arranged between the rotatable sleeve and the vertical filtering tank, a first flow guide plate is arranged at the position, between the first-stage filtering assembly and the second-stage filtering assembly, of the vertical filtering tank, and a second flow guide plate is arranged at the position, between the second-stage filtering assembly and the third-stage filtering assembly, of the vertical filtering tank; filter screen rings of the first-stage filter assembly, the second-stage filter assembly and the third-stage filter assembly are fixedly connected with the outer wall of the rotatable sleeve, and a radial cleaning brush body tightly connected with the lower surfaces of the filter screen rings is fixed on the inner wall of the vertical filter tank. The equipment improves the filtering efficiency on one hand, and enhances the filtering effect on the other hand.

The method includes: after the data middle station is built, importing the existing link driver file and device driver file in the local station of the equipment monitoring system; according to the link information composed of the monitored equipment, selecting the link driver file to configure the link driver information; according to the device information of all monitored devices in the link, selecting the device driver file to configure the device driver information; according to the monitoring interface specification requirements and network device configuration requirements of the monitoring device, connecting the monitored device to the network of the local station equipment monitoring system through the network device; according to the link and device conditions, configuring the data interaction information between the local station and the data middle station; through the main interface of the local station or the main interface of the data middle station, checking the equipment and link conditions of the monitored device. The present invention can realize the construction of a plug-and-play monitoring system using driver files.

One disclosure of the present specification proposes an operation method at a terminal. The method may comprise: a step of receiving, from a base station, system information including access control-related information on industrial signaling and / or data; a step of sending industrial signaling or data and determining an access type according to the access identifier; a step of performing a check for access control (Unified Access Control) on the basis of the access type and the access control related information; a step for determining a radio resource control (RRC) establishment cause or an RRC recovery cause on the basis of the access type when the access type has passed from the check, and a step for determining a radio resource control (RRC) establishment cause or an RRC recovery cause on the basis of the access type; and a step of transmitting, to the base station, an RRC message including the determined RRC establishment cause or RRC recovery cause.

The invention relates to the field of data processing, in particular to a public transport operation management scheduling system, and solves the problems that an existing intelligent public transport scheduling and management system cannot analyze urban buses in the driving process, so that the subsequent departure condition of the urban buses is scheduled, and the service life of the urban buses is prolonged. The problems of poor riding environment and serious traffic jam due to the fact that the driving route of the city bus cannot be analyzed and the form route of the subsequent city bus is changed are solved. The system can monitor the congestion degree of urban buses in real time, perform early warning and scheduling in advance, provide a comfortable riding environment and safe travel experience for passengers, reduce potential safety hazards caused by carriage congestion, monitor the congestion condition of driving routes in real time, perform early warning and change in advance, improve the punctuality of the urban buses, and improve the driving safety of the urban buses. The travel experience and satisfaction degree of passengers are improved, and the operation efficiency of public transportation is improved.
