The application discloses a kind of multi-dimensionally regulated city high-density block health effect optimal path exploration method, comprising first obtaining the social dimension, economic dimension and material form dimension data of city high-density block, and the data is standardized processing;On this basis, social dimension function SD, economic dimension function ED and material form dimension function PMD are constructed;Further, a health effect comprehensive model H is established;Combined with population density, green coverage, road structure and building intensity and other constraint conditions, the optimal regulation path of health effect maximization is solved by using multi-objective optimization algorithm;And the model is updated in real time through dynamic feedback mechanism, realize the continuous optimization of path.The present application realizes the change from health effect evaluation to regulation path decision by constructing multi-dimensionally coupled model and path optimization mechanism, can provide scientific, quantifiable technical support for urban high-density block human settlement environment design and management, and has good application prospect.

This invention discloses a process and apparatus for positive pressure biomass gasification and co-production of charcoal. The process includes the following steps: transporting biomass fuel to a pre-furnace silo; feeding the biomass fuel into a fluidized bed gasifier via a positive pressure feeding system, and replenishing the fluidized bed gasifier with bed feed as needed via a bed feed supply system; gasifying the biomass fuel under the action of a centrifugal fan at the bottom of the fluidized bed gasifier, adjusting the supply of fluidizing air and air gasifying agent by a variable frequency centrifugal fan, thereby regulating the temperature of the fluidized bed gasifier and thus adjusting the ratio of generated gasified fuel gas to biochar; collecting and utilizing lumpy biochar at the bottom of the fluidized bed gasifier; and collecting and utilizing ash-like biochar at the top of the fluidized bed gasifier via a cyclone separator. This invention operates under positive pressure, better adapting to changes in downstream fuel gas and biochar demand, as well as changes in upstream biomass fuel.
