Embodiment Construction

[0009] The invention provides a distributed energy system for integrated recycling of energy and resources. The present invention will be further described below in conjunction with the drawings.

[0010] in figure 1 In the process flow diagram of the distributed energy system shown, the combined biogas generation unit 1, sewage treatment unit 2 and prime mover unit 3 are connected to each other to form a recycling and treatment of kitchen waste, feces and domestic sewage Then the water output of the sewage treatment unit 2 and the output of the prime mover unit 3 are connected to the water heat source unit 4; a distributed energy system with complementary renewable energy and natural gas and symbiosis of heat, electricity, clean water and fertilizer is formed .

[0011] The specific circulation process is as follows:

[0012] 1. An inlet a1 and an inlet a2 are provided in the solar energy and flue gas waste heat composite biogas generating unit 1. The kitchen waste is crushed and...

Abstract

The invention discloses a novel distributed energy system of integratedly recycling energy source and resource, comprising solar energy and smoke afterheat compounded methane generating unit, sewage treating unit, and prime mover unit, interconnected, an integrated device for recycling and treating remaining rubbishes in kitchen, dejecta, and domestic sewage, where the medium-grade water from the sewage treating unit and the smoke output from the prime mover unit are connected to a medium-grade water heat pump unit, thus forming a novel distributed energy system where renewable energy sources and natural gas are complementary and heat, electricty, clean water and fertilizer are symbiotic. And it enhances system stability, and energy source supply stability, increases matter recycling ratio and implements high efficiency, stepped energy utilization, applied to colleges, enterprises and institutions, restaurants, housing estates, etc.

Description

Technical field [0001] The invention belongs to the scope of comprehensive waste treatment technology and new energy technology, and particularly relates to a distributed energy system for integrated recycling of energy and resources for energy cascade utilization. Background technique [0002] In the new century, mankind is facing important challenges for sustainable economic and social development. In recent years, a large number of studies at home and abroad have tried to solve the contradiction between sustainable development, energy shortage and environmental pollution by taking advantage of the high efficiency, environmental protection, economy, and high reliability of distributed energy systems, and have achieved fruitful progress. Environmental protection, economy, and high reliability are based on the principle of "reduction, reuse, and resource utilization", with the basic characteristics of low consumption, low emission, and high efficiency, with the efficient utilizat...
