【摘要】：隨著國家對(duì)燃煤電廠污染物排放控制的日趨嚴(yán)格,現(xiàn)役燃煤電廠電除塵器需提效改造或通過增加新的除塵設(shè)備達(dá)到環(huán)保要求。通過對(duì)近年來國內(nèi)外煙氣除塵新技術(shù)的原理及現(xiàn)狀進(jìn)行深入分析研究,整合、集成靜電除塵器的電源配置、靜電除塵器前加裝低溫省煤器、脫硫除霧器改造、脫硫除塵一體化改造、增加濕式電除塵器等多項(xiàng)技術(shù),最終實(shí)現(xiàn)煙塵超低排放。本文以三河電廠4臺(tái)300MW等級(jí)燃煤機(jī)組為研究對(duì)象,根據(jù)該電廠所處地理位置、各機(jī)組現(xiàn)有除塵設(shè)備配置情況及運(yùn)行情況、燃用煤質(zhì)、煙氣條件、設(shè)備布局等先天因素,選擇了不同的除塵技術(shù)路線。1號(hào)、2號(hào)機(jī)組采用電除塵器入口加裝低溫省煤器+電除塵器高頻電源改造+GGH拆除+脫硫高效除霧器改造+濕式電除塵器技術(shù)路線,3號(hào)、4號(hào)機(jī)組采用電除塵器入口加裝低溫省煤器+電除塵器高頻電源改造+脫硫除塵一體化+濕式電除塵器技術(shù)路線。工程實(shí)踐表明,三河電廠4臺(tái)機(jī)組的煙氣除塵方案經(jīng)濟(jì)、可行,完全達(dá)到預(yù)期效果既煙塵排放≤5mg/m3�；鹆Πl(fā)電廠作為耗煤大戶,煙塵近零排放技術(shù)具有極高的推廣價(jià)值,對(duì)區(qū)域大氣環(huán)境治理、對(duì)實(shí)現(xiàn)燃煤電廠持續(xù)發(fā)展具有很重要的現(xiàn)實(shí)意義。
[Abstract]:With the increasingly strict emission control of pollutants in coal-fired power plants, the existing electric precipitators of coal-fired power plants need to improve their efficiency or to meet the environmental protection requirements through the addition of new dust removal equipment. Through the thorough analysis and research on the principle and present situation of the new technology of flue gas dust removal at home and abroad in recent years, integrating and integrating the power supply of electrostatic precipitator, installing low temperature economizer before electrostatic precipitator and retrofitting of desulfurization and mist remover. Desulphurization and dust removal integration reform, the addition of wet electrostatic precipitator and other technologies, the ultimate realization of ultra-low emissions of smoke and dust. In this paper, four 300MW grade coal-fired units in Sanhe Power Plant are taken as the research object. According to the location of the power plant, the configuration and operation of the existing dust removal equipment, the burning coal quality, the flue gas condition, the equipment layout and other congenital factors, etc. Different dedusting technical routes were selected. No. 1 and No. 2 units adopted the introduction of electric precipitator with low temperature economizer electric precipitator high frequency power source transformation GGH removal desulfurization and high efficiency fogger retrofit wet type electrostatic precipitator technical route No. 3 The No. 4 unit adopts the low temperature economizer at the entrance of the electric precipitator and the high frequency power supply of the electric precipitator to reform the technical route of the integrated wet electrostatic precipitator of desulphurization and dust removal. The engineering practice shows that the scheme of flue gas dust removal of 4 units in Sanhe Power Plant is economical and feasible, and the expected result is that the smoke emission is less than 5 mg / m ~ (3). As a large coal user, the technology of near zero emission of smoke and dust in coal-fired power plant has high popularization value, which is of great practical significance to regional atmospheric environment treatment and sustainable development of coal-fired power plant.
