【摘要】：目前國內(nèi)外冶煉煙氣制酸凈化工序主要采用濕法洗滌,逆流接觸法達(dá)到凈化降溫的效果,受技術(shù)、材料等因素的影響,其設(shè)備龐大、占地面積大,除塵降溫能力有限。伴隨著冶煉系統(tǒng)產(chǎn)能的不斷增加,絕對制酸系統(tǒng)凈化工序增加負(fù)擔(dān)。根據(jù)金川公司化工廠制酸系統(tǒng)觀察來看,煙氣量的增加導(dǎo)致設(shè)備內(nèi)部填料、噴頭、篦子板堵塞,塔體底部積泥嚴(yán)重。不僅降低了設(shè)備的除塵降溫效果,而且增加了人員的勞動強(qiáng)度,檢修難度增加。本文通過對凈化工序的湍沖塔、洗滌塔以及電除霧器內(nèi)部結(jié)構(gòu)和配置進(jìn)行了改造和優(yōu)化,縮短了工藝流程,洗滌效果提高,減少了占地面積,同時節(jié)省了投資。在冶煉煙氣中含塵較高的制酸系統(tǒng)中具有很高的推廣意義。
[Abstract]:At present the domestic and foreign smelting flue gas acid-making purification process mainly uses the wet method to wash, countercurrent contact method to achieve the purification cooling effect, by the technical, the material and so on factor influence, its equipment is huge, the occupation area is big, the dedusting cooling ability is limited.With the continuous increase of production capacity of smelting system, the purification process of absolute acid-making system increases the burden.According to the observation of acid-making system in chemical plant of Jinchuan Company, the increase of flue gas amount leads to the blockage of internal packing, nozzle and grate plate, and serious sludge accumulation at the bottom of tower body.It not only reduces the dedusting and cooling effect of the equipment, but also increases the labor intensity and maintenance difficulty.In this paper, the internal structure and configuration of the turbulent scouring tower, the washing tower and the electric mist remover in the purification process are reformed and optimized, the process flow is shortened, the washing effect is improved, the area of occupation is reduced, and the investment is saved at the same time.It has high popularization significance in acid making system with high dust content in smelting flue gas.
