Abstract

The invention discloses coal-to-gas multi-pollution-source integrated treatment system and method. The system comprises a normal-low pressure gasification device (11), a primary gas-solid separation device (12), a heat exchanger (13), a scrubber tower (14), a self-cleaning filter (17) and a water heat exchanger (18), wherein the normal-low pressure gasification device (11), the primary gas-solid separation device (12), the heat exchanger (13), the self-cleaning filter (17), the scrubber tower (14) and the water heat exchanger (18) are sequentially connected. The primary gas-solid separation device (12) is the following treatment device of the normal-low pressure gasification device (11), the heat exchanger (13) is the following treatment device of the primary gas-solid separation device (12), the self-cleaning filter (17) is the following treatment device of the heat exchanger (13), the scrubber tower (14) is the following treatment device of the self-cleaning filter (17), and the water heat exchanger (18) is the following treatment device of the scrubber tower (14). The system and the method solve the problems of poor environmental protection effect, serious pollution to the surrounding environment and the like in the existing process.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an integrated treatment system and method for multiple pollution sources of coal-based gas. Background technique [0002] In my country, the atmospheric and low pressure coal-to-gas process accounts for more than 50% of all gas-making processes. This process has the obvious advantages of simple gas-making process and low investment. The carbon in the raw coal forms raw coal gas under the comprehensive reaction of oxygen (air, enriched oxygen, pure oxygen) and water vapor in the primary effect gas-solid separation device. The main reaction of coal gasification: [0003] 1. Carbon oxidation reaction C+O 2 =CO 2 -393.8kJ / mol [0004] 2. Partial oxidation reaction of carbon 2C+O 2 =2CO-231.4kJ / mol [0005] 3. Carbon dioxide reduction reaction C+CO 2 =2CO+162.4kJ / mol [0006] 4. Decomposition reaction C+H of water vapor 2 o (g) =CO+H 2 +131.5kJ / ...
