The invention relates to a method for extracting lignin via paper liquor biological acidification-flocculation deposition, wherein said method comprises: the paper liquor is stored into the liquor storage; adding solid organic into biological acidification reaction container, to ferment and generate organic acid liquid, while the ferment temperature is 2-40Deg. C for 4-5 days; when the pH value of ferment liquid in the reaction container is reduced to 5-6; and the volatile fatty acid number (VFA) is 2-80mol / L at acetic acid density, to pump the acid liquid into the ferment acid liquid storage; mixing the liquor with the ferment acid liquid, depositing, and entering into the container, and discharging some; dewatering the deposit, drying to obtain the lignin.

The invention provides a device for grain drying, which mainly includes a hot air radiation bin and a heat source generator located therein, wherein the heat source generator includes a pulse burner and an infrared radiator. The grain drying device of the invention combines pulsating combustion, infrared radiation and hot air convection to simultaneously heat the grains by side-heating infrared radiation and high-frequency hot air convection with high temperature and high frequency oscillating airflow. Compared with the traditional method, the device has low fuel consumption rate and low power consumption rate, and the drying precipitation rate is increased, which greatly improves the drying efficiency.

The invention discloses a method, an intelligent gateway and a system for enabling multiple terminals to quickly log in to a website. The method comprises steps: a website access request of an internet terminal is received, wherein the website access request comprises the terminal identity of the internet terminal and a target website address; according to the terminal identity of the internet terminal, whether the internet terminal is a trusted terminal is judged; if the internet terminal is the trusted terminal, whether the target website is a trusted website is judged according to the target website address; if the accessed website is a trusted website, account password information corresponding to the target website address is queried according to the target website address; the account password information is added to the website access request; and the website access request after the account password information is added is sent to a website server. Account password filling is automatically completed for the user through the intelligent gateway, and thus, when the user accesses the internet through multiple terminals in a home network, login to the website without account input is realized.

The invention provides a semi-controlled intelligent high-power arc-free DC bus contact device (DCS), which is characterized in that a controller A, a mechanical main switch (contact switch) K, a power electronic main switch (non-contact main switch) are provided. switch) T1 and its dynamic reverse bias control circuit, its dynamic reverse bias control circuit is composed of diode D, power electronic control switch (non-contact control switch) T2, voltage source E, capacitor C, K and T1 are connected in parallel DC switch dual channel, connected between the DC emergency power supply (E02) and the DC output load (OUT), through the intelligent control of A to ensure: when the emergency power supply is turned on, the non-contact switch channel is connected first and the mechanical switch channel is connected last. When exiting, the mechanical switch channel is broken first and the non-contact switch channel is then broken, so as to avoid arcing when the DC circuit is turned on and off under load, and through the timely conduction of T2 to solve the problem that the semi-controller T1 cannot turn off the DC under load.

The invention belongs to the technical field of metallurgical iron-making devices, and specifically relates to a blast-furnace slag processing system. The blast-furnace slag processing system mainly comprises a bottom filter chamber group, a horizontal flow chamber and a circulating water chamber, wherein the bottom filter chamber group is arranged closely adjacent to a casting house in the long and narrow spare space at the casting house side and is positioned above the ground level, the horizontal flow chamber and the circulating water chamber connected in series are arranged behind the bottom filter chamber group, and the horizontal flow chamber and the circulating water chamber are positioned under the ground level. The invention is characterized in that the overall system is arrangedclosely adjacent to the casting house side, thereby avoiding the long distance conveyance of the slag-water slurry; and the bottom filter chamber is positioned above the ground level, thereby fully making use of the space in the horizontal plane and the vertical plane at the casting house side. The invention has the advantages of small occupied area, simple equipment and facility, low construction investment, low operating cost, convenient operation and maintenance and environmental friendliness, and achieves the effects of environmental protection, high efficiency and energy saving. The invention can be widely used in the blast-furnace slag processing system, and can also be used in other slag-flushing processing systems.
