Summary: The study investigated the impact of pulse-jet cleaning interval on the filtration performance of a pleated filter, finding that the effective filtration area decreased over time regardless of the interval length. Increasing the interval could help suppress the reduction in effective filtration area. The resistance coefficient of the filter media increased with decreasing pulse-jet interval, which in turn improved total dust collection efficiency.

Summary: The dust-cleaning efficiency of the ceramic filter tube is crucial for the stable operation of the dust removal system, and the type of nozzle used significantly affects its performance. This study compared the dust-cleaning effect of four types of nozzles on the ceramic filter tube and found that the tubular and induction nozzles can improve the deviation angle of pulse-jet airflow. The residual pressure drop was found to change exponentially with the dust removal quality under different nozzle types.

Summary: The re-deposition of detached dust is an important issue during filter regeneration and can be reduced by using multi-pulsing jet cleaning schemes. Experimental testing was conducted using a pilot-scale pulse-jet cleaning dust collector with a vertically installed pleated filter cartridge. It was found that the multi-pulsing jet with a short pulse interval effectively inhibited dust re-deposition, while a longer pulse interval significantly decreased re-deposition. The multi-pulsing scheme extended the duration of reverse pulse flow, allowing more time for detached dust to fall freely, thus inhibiting re-deposition.

Summary: The research introduced a dry-wet mixed chemical method to improve the collection and removal efficiency of fine coal dust particles. By using an ultrasonic atomizer to transform chemical polymer solution into fine droplets and adding it into the dust removal process, the capture and removal of coal dust particles of less than 500 mesh were significantly enhanced. The modified carboxymethyl chitosan polymer (AM/AA-CMCS) showed promising results in wetting, binding, and agglomerating coal dust particles.

Summary: The release behavior of dust particles can be divided into five stages: radial expansion, axial crack, flaky release, irregular disruption, and secondary deposition. Cleaning performance of smaller sized dust particles is less efficient compared to larger ones, mainly because large, flaky-shaped dust aggregates are easily broken into smaller fragments during irregular disruption, forcing more particles back to the filter surface during secondary deposition. Also, a low-pressure and long-pulse width cleaning method improved the cleaning efficiency of ultrafine test dust from 81.4% to 95.9%.

Summary: Liquid flow experiences head loss due to viscous force, surface tension, friction force, etc. Some of the energy is irreversibly converted into heat and dissipates into the environment. Head loss is intensified in turbulent state. Currently, there are few studies exploring the laws of head loss caused by secondary flow, cavitation intensity, and turbulence intensity. In this study, the head losses in different sections of a jet pump were investigated by controlling the cavitation number, the secondary flow rate, and the inlet pressure. The experimental results were analyzed using computational fluid dynamics. The results indicate that increasing the secondary flow rate can weaken the variations in the transitional stage of cavitation. Additionally, the cavitation number, secondary flow rate, and inlet pressure have varying influences on head loss. Cavitation intensity and turbulence intensity are the main factors for head loss and jet temperature difference. In particular, the influence of the secondary flow rate on head loss provides guidance for reducing energy loss and expanding the stable range of the jet. Moreover, the main factors of energy loss caused by jet cavitation were analyzed in detail, which can effectively facilitate pipeline design to reduce local and frictional head loss.

Summary: A double chamber electrochemical system was developed, consisting of a boron-doped diamond anode and a graphite cathode, which efficiently degrades sulfamethoxazole (SMX) and generates hydrogen peroxide (H2O2) simultaneously. The system showed excellent performance at optimized conditions, achieving SMX degradation of 95% and COD reduction of 90% after 180 minutes of electrolysis, while accumulating around 535 μM H2O2. A degradation pathway for SMX was proposed based on the identification of five intermediates.

Summary: Concentrated Solar Power (CSP) is a renewable energy technology that uses heliostats to concentrate solar irradiance onto a receiver, where a fluid is used as a heat carrier. Using gas/solid suspensions as heat transfer medium in CSP offers advantages over other fluids, including higher achievable temperatures. Recent experiments have shown promising results using upflow bubbling fluidized beds for heat transfer in CSP systems. Challenges still remain in transferring particles between different components of the system.

Summary: This study investigated the degradation kinetics and mechanisms of different types of recalcitrant organic pollutants (ROPs) using a biochar-CuO/periodate (PI) system. The study found that the pH had significant effects on the formation of oxidative species, with the system being most efficient at pH 7. The system was able to efficiently remove methylene blue (MB) at pH 7, while under highly alkaline pH values, the degradation kinetics of the pollutant were lower. The system maintained its efficiency for other types of ROPs and could detoxify MB.
