Embodiment Construction

[0026] The utility island that provides heat and electricity is composed of gasification system, steam power generation system, air separation system, solid waste treatment system and sewage treatment system.

[0027] The gasification system is as follows: a part of the syngas obtained by gasifying the gasification raw materials with a gasification agent in a gasifier is separated to obtain pure CO and H 2 , the unseparated synthesis gas is supplied as fuel gas to relevant users respectively; the coal used in the gasification system is gas coal, lignite or long-flame coal, and the gasifier is Texaco furnace, Shell gasifier or aerospace gasifier, Gasification agent is H 2 O.CO 2 , O 2 or H 2 ; The hydrogen-to-carbon ratio of the syngas in the gasification system is 0.5-2.5, and the total syngas output is 80,000-350,000 m 3 / h, H 2 The output is 50,000 to 250,000 m 3 / h, CO production is 30,000 to 50,000 m 3 / h, the output of fuel gas is 10,000 to 80,000 m 3 / h.

Abstract

The invention discloses a public engineering island for supplying heat and power, which consists of a gasification system, a steam power generating system, an air separation system, a solid waste treatment system and a sewage treatment system. The public engineering island has the characteristics that energy and gas raw material media can be uniformly supplied in the whole industrial park, and users do not need to build self energy supply stations. Investment cost spent for building, maintaining and managing main body projects and the like can be greatly reduced, which is favorable to attracting investment. In the public engineering island, concentrated stage processing and utilization are carried out on different resources and natures of 'three wastes' and the clean production and the efficient energy comprehensive utilization of the industrial park are favorably realized. With the public engineering island, relevant or similar enterprises of upstream and downstream products can be attracted to aggregate, and the production cost can be reduced. Besides, the public engineering island is favorable to the vertical and horizontal extension of the product chain and the realization of industry cycle chaining.

Description

technical field [0001] The invention belongs to the technical field of clean energy and chemical engineering, in particular to a utility island for providing heat and electricity. Background technique [0002] Energy has become a topic of increasing international concern today. my country's energy composition is characterized by more coal, less oil and less gas. At present, with the continuous development of the national economic situation, the coal processing industry is also growing, and the accompanying high energy consumption, high pollution and environmental pressure are becoming more and more serious. It is a major technical problem in the field of energy and chemical industry to achieve circular economy, meet the requirements of energy saving and emission reduction, and take the road of sustainable development and low-carbon economy. [0003] At present, most of the air separation gas, synthesis gas, steam and other media and energy required by most chemical and petr...
