在打葉復(fù)烤車間里，煙葉經(jīng)過多道工序的處理，釋放出大量粉塵，讓車間仿佛籠罩在迷霧之中，嚴(yán)重影響能見度，不僅威脅著工人的身體健康，還存在一定的安全隱患。想要打破這層 “迷霧”，需要一套全方位、多層次的高效除塵方案，從源頭控制到末端治理，多管齊下重塑清朗的作業(yè)環(huán)境。

　　In the tobacco roasting workshop, after multiple processes, a large amount of dust is released from the tobacco leaves, making the workshop seem shrouded in mist, seriously affecting visibility. This not only threatens the physical health of workers, but also poses certain safety hazards. To break through this "fog", a comprehensive and multi-level efficient dust removal plan is needed, from source control to end treatment, to reshape a clear working environment through multiple measures.

　　首先，從生產(chǎn)工藝環(huán)節(jié)入手，減少粉塵的產(chǎn)生是關(guān)鍵的第一步。在煙葉的預(yù)處理階段，通過優(yōu)化煙葉的加濕工藝，讓煙葉保持合適的含水率。當(dāng)煙葉濕度適宜時(shí)，在后續(xù)的打葉、風(fēng)分等工序中，破碎產(chǎn)生的粉塵量會明顯降低。比如，精確控制加濕器的噴水量和噴霧均勻度，使煙葉在進(jìn)入打葉機(jī)前達(dá)到理想的柔軟度，降低煙葉碎裂成細(xì)小粉塵的概率。此外，對打葉機(jī)的刀片進(jìn)行改良，采用更鋒利、更耐磨且設(shè)計(jì)更科學(xué)的刀片，讓煙葉在切割過程中受力更均勻，減少因切割不順暢而產(chǎn)生的額外粉塵。同時(shí)，合理調(diào)整風(fēng)分設(shè)備的風(fēng)速和風(fēng)量，既能保證有效分離煙葉和雜質(zhì)，又避免因風(fēng)速過大將煙葉過度吹碎產(chǎn)生大量粉塵。

　　Firstly, starting from the production process, reducing the generation of dust is the key first step. In the pre-treatment stage of tobacco leaves, by optimizing the humidification process of tobacco leaves, the appropriate moisture content of tobacco leaves can be maintained. When the humidity of tobacco leaves is suitable, the amount of dust generated by crushing will be significantly reduced in subsequent processes such as leaf cutting and air conditioning. For example, precisely control the amount of water sprayed by the humidifier and the uniformity of spray, so that the tobacco leaves can reach the ideal softness before entering the thresher, and reduce the probability of tobacco leaves breaking into fine dust. In addition, the blades of the tobacco cutting machine have been improved by using sharper, more wear-resistant, and scientifically designed blades, which make the force on the tobacco leaves more uniform during the cutting process and reduce the additional dust generated due to poor cutting. At the same time, adjusting the wind speed and volume of the air separation equipment reasonably can ensure effective separation of tobacco leaves and impurities, while avoiding excessive crushing of tobacco leaves due to excessive wind speed, resulting in a large amount of dust.

　　安裝高效的除塵設(shè)備是直接解決粉塵彌漫問題的核心手段。在車間內(nèi)合理布局吸塵罩，將其安裝在粉塵產(chǎn)生的源頭位置，如打葉機(jī)、風(fēng)分機(jī)、篩分機(jī)等設(shè)備的出料口和進(jìn)料口。吸塵罩的設(shè)計(jì)要符合空氣動力學(xué)原理，確保能夠最大限度地捕捉粉塵。通過管道將吸塵罩與大型的集中式除塵器相連，常見的布袋除塵器就十分有效，它利用纖維織物的過濾作用，當(dāng)含塵氣體通過濾袋時(shí)，粉塵顆粒被阻留在濾袋表面，清潔空氣則通過濾袋排出。定期對布袋進(jìn)行清理和更換，防止因布袋堵塞影響除塵效果。另外，也可搭配使用旋風(fēng)除塵器，先通過旋風(fēng)除塵器去除較大顆粒的粉塵，減輕后續(xù)布袋除塵器的負(fù)擔(dān)，提高整體除塵效率。兩種設(shè)備相互配合，能夠有效降低車間內(nèi)的粉塵濃度。

　　Installing efficient dust removal equipment is the core means to directly solve the problem of dust dispersion. Reasonably arrange the vacuum hood in the workshop and install it at the source of dust generation, such as the discharge and feed ports of equipment such as leaf blowers, fans, and screening machines. The design of the vacuum hood should comply with aerodynamic principles to ensure maximum capture of dust. By connecting the vacuum hood to a large centralized dust collector through a pipeline, the common bag filter is very effective. It utilizes the filtering effect of fiber fabric. When the dusty gas passes through the filter bag, the dust particles are trapped on the surface of the filter bag, and the clean air is discharged through the filter bag. Regularly clean and replace the bag to prevent dust removal from being affected by bag blockage. In addition, a cyclone dust collector can also be used in combination to remove larger particles of dust first, reducing the burden on subsequent bag filters and improving overall dust removal efficiency. The combination of two devices can effectively reduce the dust concentration in the workshop.

　　加強(qiáng)車間的通風(fēng)換氣系統(tǒng)，能進(jìn)一步改善粉塵彌漫的狀況。設(shè)計(jì)合理的通風(fēng)管道和排風(fēng)口，確保車間內(nèi)的空氣能夠形成良好的流動循環(huán)。采用機(jī)械通風(fēng)與自然通風(fēng)相結(jié)合的方式，在車間頂部安裝排風(fēng)扇，及時(shí)排出積聚在車間上方的粉塵；在車間墻壁上設(shè)置可開啟的窗戶，在天氣條件允許時(shí)，打開窗戶進(jìn)行自然通風(fēng)，引入新鮮空氣。同時(shí)，對進(jìn)風(fēng)口進(jìn)行過濾處理，防止室外的灰塵進(jìn)入車間，保證進(jìn)入車間的空氣潔凈。通過良好的通風(fēng)換氣，不僅能降低車間內(nèi)粉塵的濃度，還能改善車間的空氣質(zhì)量，為工人創(chuàng)造更舒適的工作環(huán)境。

　　Strengthening the ventilation system in the workshop can further improve the situation of dust dispersion. Design reasonable ventilation ducts and exhaust outlets to ensure good air circulation in the workshop. Adopting a combination of mechanical ventilation and natural ventilation, installing exhaust fans at the top of the workshop to promptly remove dust accumulated above the workshop; Install openable windows on the workshop walls, and when weather conditions permit, open the windows for natural ventilation to introduce fresh air. At the same time, filter the air inlet to prevent outdoor dust from entering the workshop and ensure clean air entering the workshop. Through good ventilation, not only can the concentration of dust in the workshop be reduced, but the air quality in the workshop can also be improved, creating a more comfortable working environment for workers.

　　建立完善的清潔管理制度和工人防護(hù)措施也必不可少。制定嚴(yán)格的日常清潔計(jì)劃，安排專人定期對車間地面、設(shè)備表面、墻壁等進(jìn)行清掃，使用吸塵器或濕布擦拭，避免采用揚(yáng)塵較大的清掃方式。定期對車間的除塵設(shè)備進(jìn)行維護(hù)保養(yǎng)，檢查管道是否有破損、漏風(fēng)，除塵器的運(yùn)行是否正常等，確保除塵設(shè)備始終處于高效運(yùn)行狀態(tài)。為工人配備專業(yè)的防塵口罩、防護(hù)眼鏡、工作服等個(gè)人防護(hù)用品，并加強(qiáng)對工人的培訓(xùn)，讓他們了解粉塵的危害和正確的防護(hù)方法，提高自我保護(hù)意識。

　　Establishing a comprehensive cleaning management system and worker protection measures are also essential. Develop a strict daily cleaning plan, assign dedicated personnel to regularly clean the workshop floor, equipment surfaces, walls, etc., using a vacuum cleaner or damp cloth to wipe, and avoid using cleaning methods with high dust. Regularly maintain and upkeep the dust removal equipment in the workshop, check for any damage or air leakage in the pipelines, and ensure the normal operation of the dust collector to ensure that the dust removal equipment is always in efficient operation. Equip workers with professional dust masks, protective goggles, work clothes and other personal protective equipment, and strengthen training for workers to understand the hazards of dust and correct protection methods, and improve self-protection awareness.
