Abstract: The present invention discloses a flue gas low-temperature adsorption denitrification method, including: pressurizing a flue gas that has been subjected to dust removal and desulfurization, precooling the pressurized flue gas, cooling the precooled flue gas to a temperature lower than room temperature by a flue gas cooling system, flowing the flue gas at the temperature lower than room temperature into a low-temperature denitrification system, performing physical adsorption denitrification in the low-temperature denitrification system, precooling the flue gas that has been subjected to dust removal and desulfurization with the denitrificated flue gas, and flowing the heat-absorbed clean flue gas into a chimney to be discharged.

Abstract: A split-type device for measuring rock mass deformation under high hydraulic pressure and a construction method and use thereof. Main components of the device include a metal measuring rod, a magnetic iron core, a shell, a waterproof coil framework, a coil, a tail accessory, a cable clamp, a cable, a signal processing bin, etc. Main electronic components are treated by adopting the all-metal shell and a vacuum particle sealing double-layer sealing process, and have hydraulic pressure resistance of 5 MPa or above. Measurement signals feature centralized processing, digitization and dual utilization of signals, i.e., after data of a plurality of sensors is processed in an electronic bin and then digitized signals are connected to an independent reader outside the bin or a centralized acquisition device for in-situ tests.

Abstract: Disclosed is a flue gas low-temperature adsorption denitration system and process. The system includes a booster fan, a cold energy recoverer, a flue gas cooling system, a flue gas switching valve, and two denitration adsorption towers. An inlet of the booster fan is in communication with an inlet flue gas pipeline. The booster fan, the cold energy recoverer, the flue gas cooling system, the flue gas switching valve, and the denitration adsorption towers are sequentially communicated. An outlet of the flue gas switching valve is in communication with each of the two second denitration adsorption towers. Flue gas outlets of the two denitration adsorption towers are in communication with a flue gas manifold. The flue gas manifold is communicated with the cold quantity recoverer. Two denitration adsorption towers take turns to carry out denitration and regeneration processes, so that continuous denitration operations of the system can be achieved.
