The particle collision behavior and heat transfer performance are investigated to reveal the heat transfer enhancement and fouling prevention mechanism in a Na_(2)SO_(4) circulating fluidized bed *** particle collision signals are analyzed with standard deviation by varying the amount of added particles ε(1%–3%),circulation flow velocity u(0.37–1.78 m·s^(-1)),and heat flux q(7.29–12.14 kW·m^(-2)).The results show that the enhancement factor reach up to 14.6%by adding polytetrafluoroethylene particles at ε=3%,u=1.78 m·s^(-1),and q=7.29 kW·m^(-2).Both the standard deviation of the particle collision signal and enhancement factor increase with the increase in the amount of added *** standard deviation increases with the increase in circulation flow velocity;however,the enhancement factor initially decreases and then *** standard deviation slightly decreases with the increase in heat flux at low circulation flow velocity,but initially increases and then decreases at high circulation flow *** enhancement factor decreases with the increase in heat *** enhancement factor in Na_(2)SO_(4) solution is superior to that in water at high amount of added *** empirical correlation for heat transfer is established,and the model results agree well with the experimental data.

A liquid-solid circulating fluidized bed boiler is designed and built for visualization research by applying the fluidized bed heat transfer and fouling prevention technology to the water side of the boiler. Four types of engineering plastic particles with different physical properties are selected as the solid working media. The effect of particle types on the fluidization and distribution of particles in the boiler is investigated under different feedwater flow rates and amount of added particles by using the charge couple device image measurement and acquisition system. The results show that all kinds of particles can't be normally fluidized and accumulate in the drum at low amount of added particles and feedwater flow rate. The particles with great density and low sphericity are more likely to accumulate. The average solid holdup in the riser tubes increases with the increase in feedwater flow rate and the amount of added particles. The non-uniform degree of particle distribution in the riser tubes generally decreases with the increase in feedwater flow rate and the amount of added particles. The particles with small density and settling velocity have high average solid holdup in the riser tubes under close sphericity. In generally,the smaller the density and settling velocity, the more uniform the particle distribution in the riser ***-dimensional diagrams of the non-uniform degree of particle distribution in the riser tubes of the boiler are established.

To cultivate high-quality rule-of-law talents, XI Jinping Thought on the Rule of Law must be fully carried out, the spirit of the Opinions on Strengthening Law Education and Law Theory Research in the New Era must be implemented, the law teaching system must be improved, and the paths of talent cultivation must be optimized. The first is improving the ideological and political education and legal professional ethics education, teaching the ideological and political courses and legal professional ethics courses well in line with the essence of “bringing out the facts and reasons,” and doing an excellent job in ideological and political theory teaching in all courses from the perspective of all persons, the whole process, and all-around education. The second is improving the multi-level law education and teaching system and quality certification system, supporting and developing legal vocational education, consolidating undergraduate law education, boosting graduate law education, and developing professional degree education in law. The third is improving the curriculum system for law majors, accelerating the construction of courses reflecting the achievements in the practice of state governance and administration in the new era, such as the science of intra-Party regulations, the science of oversight law, and social governance jurisprudence, and so on, exploring the availability of the characteristic new course “science of field law,” and setting up diversified major-oriented modules to accommodate a large number of new courses. The fourth is improving the practical teaching and cooperative education system, adapting to the new form and requirement of “internet + education” to innovate education and teaching methods and means, strengthening the cooperation between law schools and rule-of-law work departments and legal service providers, enhancing education through work practice, and improving the in-service education system for rule-of-law talents.
