【正文】 吉林化工學(xué)院畢業(yè)設(shè)計(jì)（說明書） I 摘 要 隨著經(jīng)濟(jì)的發(fā)展和人民生活水平的提高，工作人員對(duì)自己的身心健康要求越來越高，同時(shí)更加關(guān)注工作環(huán)境。工業(yè)通風(fēng)是通風(fēng)工程的重要部分，其主要任務(wù)是降低工作環(huán)境中的粉塵濃度、有害氣體等，創(chuàng)造良好的生產(chǎn)環(huán)境和保護(hù)大氣。做好工業(yè)通風(fēng)工作，一方面能夠改善生產(chǎn)車間及其周圍的空氣條件，防止職業(yè)病的產(chǎn)生、保護(hù)人民健康、提高勞動(dòng)生產(chǎn)率；另一方面可以保證生產(chǎn)正常運(yùn)行，提高產(chǎn)品質(zhì)量。如何做好工業(yè)通風(fēng)除塵，職業(yè)安全健康管理以及環(huán)境保護(hù)是我們安全工作人員的一項(xiàng)重要職責(zé)。 此次畢業(yè)設(shè)計(jì)針對(duì)某企業(yè)電鍍車間進(jìn)行通風(fēng)除塵系統(tǒng)設(shè)計(jì)。通 過對(duì)該企業(yè)電鍍車間各工段進(jìn)行危險(xiǎn)有害因素辨識(shí)，找出問題所在，采取有效措施將污染物進(jìn)行收集、凈化并排至室外，控制車間的粉塵濃度，提高車間的空氣質(zhì)量，使車間內(nèi)有害物濃度低至國家衛(wèi)生標(biāo)準(zhǔn)規(guī)定的最高允許濃度以下。本研究通過對(duì)車間內(nèi)有害因素進(jìn)行分析，根據(jù)分析結(jié)果，設(shè)計(jì)通風(fēng)系統(tǒng)。 關(guān)鍵詞 ：電鍍車間 ； 粉塵 ； 通風(fēng)除塵 吉林化工學(xué)院畢業(yè)設(shè)計(jì)（說明書） II Abstract With economic development and people39。s living standards improve, the staff of their own physical and mental health have bee increasingly demanding, and more attention to the work environment. Industrial Ventilation Ventilation is an important part of the project, whose main task is to reduce the concentration of dust in the working environment, harmful gases, to create a good production environment and protection of the atmosphere. Industrial ventilation work to do, on the one hand to improve plant production and its surrounding atmospheric conditions to prevent the generation of occupational diseases, protecting people39。s health, improve labor productivity。 on the other hand can ensure normal operation of production, improve product quality. How to industrial ventilation and dust, occupational safety and health management and environmental protection is a safety of our staff is important duties. The graduation design for ventilation and dust removal system design an enterprise plating shop. Workshop harmful substances by the enterprise electroplating workshop each station identification of hazardous and harmful factors, identify problems and take effective measures to collect pollutants, purifying side by side outdoors, plant control dust concentration, improve air quality workshop, so concentrations as low as the national health standards for the maximum allowable concentration less. This study of the workshop harmful factors were analyzed, according to the results of the analysis, design of ventilation systems. Keywords: electroplating workshops, dust, ventilation dust 吉林化工學(xué)院畢業(yè)設(shè)計(jì)（說明書） III 目 錄 摘 要 ........................................................................................................................
