工藝改進(jìn)

　　Process Improvement

　　分析生產(chǎn)工藝，尋找可能產(chǎn)生粉塵的環(huán)節(jié)，通過改進(jìn)工藝減少粉塵的產(chǎn)生。例如，在物料破碎過程中，采用濕式破碎技術(shù)，將水加入破碎設(shè)備中，使物料在濕潤狀態(tài)下破碎，可有效抑制粉塵飛揚(yáng)。對于一些產(chǎn)生粉塵的加工過程，盡量采用密閉式生產(chǎn)設(shè)備，將粉塵源封閉在設(shè)備內(nèi)部，減少粉塵向車間空氣中的散發(fā)。如在粉料包裝工序，使用自動包裝機(jī)，并配備密閉吸塵罩，防止粉料泄漏。

　　Analyze the production process, identify potential areas that may generate dust, and reduce dust generation by improving the process. For example, in the process of material crushing, wet crushing technology is used to add water to the crushing equipment to crush the material in a moist state, which can effectively suppress dust flying. For some processing processes that generate dust, try to use enclosed production equipment to seal the dust source inside the equipment and reduce the emission of dust into the workshop air. In the powder packaging process, an automatic packaging machine should be used and equipped with a sealed vacuum hood to prevent powder leakage.

　　物料管理

　　Material Management

　　合理規(guī)劃物料的儲存和運輸方式，對易產(chǎn)生粉塵的物料，如煤炭、礦石等，應(yīng)采用封閉儲存，如筒倉或密閉倉庫。在物料裝卸過程中，采取噴淋降塵措施，減少裝卸過程中的粉塵飛揚(yáng)。優(yōu)化物料的輸送方式，盡量采用皮帶輸送機(jī)、氣力輸送等密閉輸送方式，避免物料在輸送過程中暴露在空氣中產(chǎn)生粉塵。

　　Reasonably plan the storage and transportation methods of materials, and for materials that are prone to dust generation, such as coal, ore, etc., closed storage should be adopted, such as silos or sealed warehouses. During the material loading and unloading process, spray dust reduction measures are taken to reduce dust flying during the loading and unloading process. Optimize the conveying method of materials, and try to use closed conveying methods such as belt conveyors and pneumatic conveying to avoid dust generation caused by exposure of materials to the air during the conveying process.

　　通風(fēng)系統(tǒng)設(shè)計

　　Ventilation system design

　　全面通風(fēng)

　　Comprehensive ventilation

　　根據(jù)車間的大小、生產(chǎn)設(shè)備的布局以及粉塵產(chǎn)生的特點，設(shè)計合理的全面通風(fēng)系統(tǒng)。一般來說，車間內(nèi)的通風(fēng)換氣次數(shù)應(yīng)根據(jù)粉塵濃度和衛(wèi)生標(biāo)準(zhǔn)來確定，通常每小時換氣次數(shù)在 5 - 15 次左右。合理設(shè)置進(jìn)風(fēng)口和排風(fēng)口的位置，使車間內(nèi)形成良好的氣流組織，避免氣流短路和死角，確保新鮮空氣能夠均勻地分布到車間各個角落，同時將含塵空氣有效地排出車間。

　　Design a reasonable comprehensive ventilation system based on the size of the workshop, the layout of production equipment, and the characteristics of dust generation. Generally speaking, the ventilation and air exchange rate in the workshop should be determined based on dust concentration and hygiene standards, usually around 5-15 times per hour. Reasonably set the positions of the air inlet and outlet to form a good airflow organization in the workshop, avoid airflow short circuits and dead corners, ensure that fresh air can be evenly distributed to all corners of the workshop, and effectively discharge dusty air from the workshop.

　　局部通風(fēng)

　　Local ventilation

　　對于粉塵產(chǎn)生較為集中的設(shè)備或工作區(qū)域，設(shè)置局部通風(fēng)系統(tǒng)。如在焊接工位上方設(shè)置局部排風(fēng)罩，將焊接時產(chǎn)生的煙塵直接收集并排出車間，防止煙塵在車間內(nèi)擴(kuò)散。局部排風(fēng)罩的設(shè)計應(yīng)根據(jù)粉塵源的特點和氣流運動規(guī)律進(jìn)行，確保能夠有效地捕捉粉塵。例如，對于高溫、高速氣流產(chǎn)生的粉塵源，應(yīng)采用傘形罩或吹吸式排風(fēng)罩，提高捕塵效率。高效除塵設(shè)備選擇。

　　For equipment or work areas where dust generation is concentrated, a local ventilation system should be installed. If a local exhaust hood is installed above the welding station, the smoke and dust generated during welding can be directly collected and discharged from the workshop to prevent the spread of smoke and dust in the workshop. The design of local exhaust hoods should be based on the characteristics of dust sources and the laws of airflow movement to ensure effective capture of dust. For example, for dust sources generated by high temperature and high-speed airflow, umbrella shaped hoods or blow suction exhaust hoods should be used to improve dust capture efficiency. Selection of high-efficiency dust removal equipment.

　　布袋除塵器

　　bag filter

　　適用于處理常溫、干燥、非纖維性粉塵。其工作原理是利用纖維布袋對粉塵的過濾作用，將粉塵截留在布袋表面，凈化后的空氣通過布袋排出。布袋除塵器的過濾效率高，可達(dá) 99% 以上，能夠有效去除微米級的粉塵顆粒。在選擇布袋除塵器時，要根據(jù)車間的粉塵濃度、處理風(fēng)量、粉塵性質(zhì)等因素來確定除塵器的型號和規(guī)格。同時，要注意布袋的材質(zhì)和質(zhì)量，選擇耐磨損、耐腐蝕、透氣性好的布袋，以延長除塵器的使用壽命。

　　Suitable for handling room temperature, dry, non fibrous dust. Its working principle is to use the filtering effect of fiber cloth bags on dust, trapping the dust on the surface of the cloth bag and discharging the purified air through the cloth bag. The filtration efficiency of bag filter is high, reaching over 99%, and it can effectively remove micron sized dust particles. When choosing a bag filter, the model and specifications of the dust collector should be determined based on factors such as workshop dust concentration, processing air volume, and dust properties. At the same time, it is important to pay attention to the material and quality of the bag, and choose bags that are wear-resistant, corrosion-resistant, and have good breathability to extend the service life of the dust collector.

　　旋風(fēng)除塵器

　　cyclone dust collector

　　主要用于處理大顆粒粉塵，其工作原理是利用旋轉(zhuǎn)氣流產(chǎn)生的離心力，使粉塵顆粒在離心力的作用下與氣流分離，從而達(dá)到除塵的目的。旋風(fēng)除塵器結(jié)構(gòu)簡單、運行穩(wěn)定、維護(hù)成本低，對于粒徑大于 5 微米的粉塵具有較高的去除效率。對于一些粉塵濃度較高、顆粒較大的車間，如礦山破碎車間，可以將旋風(fēng)除塵器作為一級除塵設(shè)備，先對大顆粒粉塵進(jìn)行預(yù)分離，然后再將含塵氣體送入其他高效除塵設(shè)備進(jìn)行進(jìn)一步處理。

　　Mainly used for processing large particle dust, its working principle is to use the centrifugal force generated by rotating airflow to separate dust particles from the airflow under the action of centrifugal force, thereby achieving the purpose of dust removal. The cyclone dust collector has a simple structure, stable operation, and low maintenance cost, and has a high removal efficiency for dust particles larger than 5 microns. For some workshops with high dust concentration and large particles, such as mining crushing workshops, cyclone dust collectors can be used as primary dust removal equipment to first pre separate large particle dust, and then send the dust containing gas to other high-efficiency dust removal equipment for further processing.

　　維護(hù)與管理設(shè)備維護(hù)

　　Maintenance and management of equipment maintenance

　　制定完善的除塵設(shè)備維護(hù)計劃，定期對設(shè)備進(jìn)行檢查、清潔、保養(yǎng)和維修。例如，對于布袋除塵器，要定期檢查布袋的破損情況，及時更換破損的布袋；對于靜電除塵器，要定期清理集塵極和電暈極上的粉塵，確保電場強(qiáng)度正常。建立設(shè)備維護(hù)檔案，記錄設(shè)備的運行情況、維護(hù)內(nèi)容和維修記錄等信息，以便及時發(fā)現(xiàn)設(shè)備存在的問題，并采取相應(yīng)的措施進(jìn)行處理。

　　Develop a comprehensive maintenance plan for dust removal equipment, and regularly inspect, clean, maintain, and repair the equipment. For example, for bag filters, it is necessary to regularly check the damage of the bags and replace damaged bags in a timely manner; For electrostatic precipitators, it is necessary to regularly clean the dust on the collection electrode and corona electrode to ensure normal electric field strength. Establish equipment maintenance records to document the operation status, maintenance content, and repair records of the equipment, in order to promptly identify any issues with the equipment and take appropriate measures to address them.

　　人員培訓(xùn)

　　personnel training

　　對車間操作人員和維護(hù)人員進(jìn)行專業(yè)培訓(xùn)，使其熟悉除塵設(shè)備的工作原理、操作方法和維護(hù)要點。培訓(xùn)內(nèi)容應(yīng)包括設(shè)備的啟動、停止、日常巡檢、故障排除等方面的知識和技能。加強(qiáng)對員工的環(huán)保意識教育，提高員工對粉塵危害的認(rèn)識，使員工能夠自覺遵守環(huán)保規(guī)章制度，積極參與車間的除塵工作。

　　Provide professional training to workshop operators and maintenance personnel to familiarize them with the working principles, operating methods, and maintenance points of dust removal equipment. The training content should include knowledge and skills in equipment startup, shutdown, daily inspection, troubleshooting, and other aspects. Strengthen environmental awareness education for employees, raise their awareness of dust hazards, and enable them to consciously abide by environmental regulations and actively participate in dust removal work in the workshop.

　　監(jiān)測與評估

　　Monitoring and Evaluation

　　定期對車間內(nèi)的粉塵濃度進(jìn)行監(jiān)測，了解粉塵污染狀況，評估除塵效果。監(jiān)測點應(yīng)設(shè)置在粉塵產(chǎn)生源附近、工人操作崗位以及車間通風(fēng)口等位置，監(jiān)測頻率一般每月至少一次。根據(jù)監(jiān)測結(jié)果，及時調(diào)整除塵設(shè)備的運行參數(shù)或采取其他改進(jìn)措施，確保車間內(nèi)的粉塵濃度符合國家衛(wèi)生標(biāo)準(zhǔn)和環(huán)保要求。通過以上從源頭治理到高效設(shè)備應(yīng)用的全面除塵方案，并加強(qiáng)維護(hù)與管理，工廠車間能夠有效降低粉塵污染，創(chuàng)造一個清潔、安全、健康的生產(chǎn)環(huán)境。

　　Regularly monitor the dust concentration in the workshop, understand the dust pollution situation, and evaluate the dust removal effect. Monitoring points should be set up near dust sources, worker operation positions, and workshop ventilation openings, with a monitoring frequency of generally at least once a month. According to the monitoring results, adjust the operating parameters of the dust removal equipment in a timely manner or take other improvement measures to ensure that the dust concentration in the workshop meets national health standards and environmental protection requirements. Through the comprehensive dust removal plan from source control to efficient equipment application, and strengthened maintenance and management, the factory workshop can effectively reduce dust pollution and create a clean, safe, and healthy production environment.
