The invention discloses a solid calcium-based carbon dioxide trapping system coupled with a coal-fired boiler and a method thereof, and belongs to the technical field of environmental protection. According to the system, a fixed bed is adopted as a reactor for absorbing CO2, CaO solid is adopted as a CO2 adsorbent, a large amount of water does not need to be consumed, and meanwhile the problem that a liquid chemical reagent serves as the CO2 adsorbent can be effectively solved. The system can efficiently capture CO2 and realize regeneration of the solid calcium-based absorbent through a fixed bed technology. And the vast majority of heat of high-temperature flue gas generated by the hot smoke generator is coupled with the coal-fired boiler, so that not only is the efficient recovery of energy promoted, but also the energy consumption of CO2 capture is remarkably reduced, and an economical and feasible strategy is provided for realizing the low-carbon target. According to the technical scheme provided by the invention, efficient capture of carbon dioxide in the flue gas discharged by the coal-fired power plant can be realized.

The invention relates to the technical field of nuclear power station equipment, in particular to a digesting agent preparation method and a method and system for removing iron-containing colloidal deposits, and the target digesting agent is obtained by synthesizing 4-aminobenzoic acid through a melt polycondensation method by using acetic acid as a catalyst. The method disclosed by the invention has the beneficial effects that the poly (aminobenzoic acid) serving as the target digestion agent is synthesized by taking 4-aminobenzoic acid as a monomer and adopting cheap and environment-friendly acetic acid as a catalyst through a melt polycondensation method for the first time. According to the innovation, the traditional synthesis process is simplified, the production cost is reduced, and the stability and efficiency of the target digesting agent in a high-temperature and high-pressure environment are also remarkably improved.

The utility model discloses a multistage rotational flow mixed type ozone oxidation wastewater treatment equipment relates to 111 technical field, this multistage rotational flow mixed type ozone oxidation wastewater treatment equipment, including upper cylinder, lower cylinder, flow guide inner piece and flow guide impeller group, upper cylinder is located at the top of lower cylinder, and the upper cylinder and lower cylinder port detachable connection and intercommunication, and the inner wall of upper cylinder and lower cylinder all is provided with the flow guide inner piece of helical distribution along its axial direction. The application can significantly strengthen the gas-liquid mixing effect through the combined design of the variable-diameter rotational flow cavity and the special-shaped flow guide blade. The variable-diameter structure can form an alternating flow field in the cavity, and the special-shaped flow guide blade can cut and guide the fluid. This design can promote the continuous fragmentation and dispersion of ozone bubbles in turbulent disturbance, effectively increase the gas-liquid contact area, and improve the collision frequency of ozone molecules and wastewater pollutants. The problem of insufficient gas-liquid mixing and low mass transfer efficiency in traditional technology is solved.

The present application relates to the technical field of luggage consignment label material, and discloses a kind of to stick luggage consignment label material and preparation method thereof, adopt the surface printing layer, heat response protective layer, hydrosol layer and backing paper layer of top-down sequentially compounded multilayer structure, surface printing layer is made by polylactic acid, polybutylene glycol terephthalate adipate and bamboo fiber blend, heat response protective layer includes the microcapsule of inside encapsulation thermochromic compound with degradable material as capsule wall, and hydrosol layer is made of polyvinyl alcohol, esterified starch and rosin glyceride.The scheme solves the environmental pollution caused by the non-biodegradable existing luggage label, and the security risk that cannot provide effective warning when encountering illegal heating disassembly.The present application will produce eye-catching alarm through microcapsule discoloration when abnormal heating, and the biodegradable material used ensures that the label can be quickly decomposed in the natural environment after being discarded, realizing the combination of safety and environmental protection.

The application discloses an activated carbon hazardous waste treatment method and relates to the field of hazardous waste treatment, aiming to solve the problems of traditional processes in parameter control, regeneration effect and safety guarantee and the like, and specifically comprises the following steps: collecting organic functional group characteristic data and water content data of activated carbon hazardous waste to be treated; inputting a machine learning model and outputting target temperature T L of a low-temperature section of a rotary kiln, target temperature T H of a high-temperature section and minimum residence time t of the high-temperature section; controlling the low-temperature section of the rotary kiln to treat the activated carbon hazardous waste in the interval [T L -15 ℃, T L +15 ℃] according to T L , and detecting the concentration of benzene series, and when the concentration is reduced to a predetermined concentration, the activated carbon hazardous waste is transported to the high-temperature section; controlling the high-temperature section of the rotary kiln to be treated for at least t minutes in the interval [T H -20 ℃, T H +20 ℃] according to T H and t; and sending the activated carbon hazardous waste from a discharge port of the rotary kiln into a quenching tower. The application improves the recycling value of the regenerated activated carbon, and takes into account the environmental protection effect and treatment economy.

The utility model discloses a kind of burner structures of high-purity magnesia sintering kiln, it is related to kiln technical field, including mounting ring, the outside of mounting ring is fixedly connected with mounting frame in annular arrangement mode, the side fixedly connected with burner body of mounting frame, the output end of burner body is movably penetrated in the inside of mounting frame.The utility model heats heating groove by burner body, removes residual moisture, carbonate in high-purity magnesia, while electric push rod drives mounting ring and burner body to carry out height reciprocating adjustment, so that heating groove is evenly heated, avoid local overheating or heating insufficient condition, to reduce the cracking, pulverization etc. Loss that high-purity magnesia is generated due to uneven heating, improve raw material utilization rate, simultaneously, uniform high-temperature environment can ensure that residual moisture and carbonate are completely decomposed, avoid impurity residue influence product purity.

The invention relates to the technical field of organic fertilizer production, and particularly discloses an agricultural waste treatment device for organic fertilizer preparation and a treatment method thereof.The agricultural waste treatment device comprises a device base, a grinding cylinder, a smashing cylinder and a discharging hopper are arranged at the top of the device base, a smashing assembly is arranged in the smashing cylinder, and a grinding assembly is arranged in the smashing cylinder; a stirring assembly is arranged in the device base, and the crushing assembly comprises a filter cylinder fixedly connected to the interior of the crushing cylinder; when agricultural wastes enter the crushing cylinder, long straws are cut into sections by virtue of a plurality of driving shafts and fall to the bottom after being crushed, the cut straws and excrement are deeply crushed and mixed by virtue of a blade I and a blade II, and the mixed wastes enter the grinding cylinder through the filter cylinder and are ground in the grinding cylinder; and the waste which does not conform to the specification is discharged through the communicating pipe, so that the waste is promoted to be in full contact, the decomposition of microorganisms is ensured, and the preparation efficiency and quality of the organic fertilizer are improved.
