集中式焊煙除塵器主要是針對治理在機械加工、鑄造廠、粉料回收、醫(yī)療生產(chǎn)、食品加工，焊接煙塵、切割、打磨、家具生產(chǎn)等行業(yè)生產(chǎn)時產(chǎn)生大量對人體有害的粉塵顆粒而設(shè)計的，處理風(fēng)量4000~60000m?/h，不同的組合滿足不同風(fēng)量的處理要求，可滿足生產(chǎn)車間多工序的粉塵收集處理，收集方式有移動吸臂式和固定收集罩等，減少粉塵逸散到車間內(nèi)，保障車間工作環(huán)境?？蓛艋罅繎腋≡诳諝庵袑θ梭w有害的粉塵顆粒。
The centralized welding smoke dust collector is mainly designed to control the large amount of harmful dust particles generated during production in industries such as mechanical processing, foundry, powder recycling, medical production, food processing, welding smoke, cutting, polishing, furniture production, etc. The processing air volume is 4000-6000m/ h. Different combinations meet the processing requirements of different air volumes and can meet the dust collection and treatment requirements of multiple processes in the production workshop. The collection methods include mobile suction arms and fixed collection covers, which reduce the escape of dust into the workshop and ensure the working environment of the workshop. It can purify a large number of dust particles suspended in the air that are harmful to the human body.
設(shè)備結(jié)構(gòu)組成:
Equipment structure composition:
本除塵器主要由前端過濾、集塵主箱體、脈沖清灰、阻火網(wǎng)、收集灰斗、支腳框架、排灰裝置、脈沖清灰系統(tǒng)組成。需防爆的工況，可加卸爆口；如需集成控制，可加PLC控制系統(tǒng)。
This dust collector mainly consists of front-end filtration, dust collection main box, pulse cleaning, fire screen, ash collection hopper, support frame, ash discharge device, and pulse cleaning system. Explosion proof working conditions can be equipped with explosion discharge ports; If integrated control is required, a PLC control system can be added.
工作原理:
Working principle:
本設(shè)備在系統(tǒng)主風(fēng)機的作用下，含塵氣體從除塵器下部或側(cè)面的進(jìn)風(fēng)口進(jìn)入除塵器的氣箱內(nèi)進(jìn)行含塵氣體的預(yù)處理，然后從底部進(jìn)入到上箱體的各除塵室內(nèi)；粉塵吸附在濾筒的外表面上，過濾后的干凈氣體透過濾筒進(jìn)入上箱體的凈氣腔并匯集至出風(fēng)口排出。
Under the action of the main fan of the system, the dust containing gas enters the air box of the dust collector from the lower or side air inlet for pre-treatment, and then enters each dust removal room of the upper box from the bottom; Dust is adsorbed on the outer surface of the filter cartridge, and the filtered clean gas enters the clean air chamber of the upper box through the filter cartridge and collects at the air outlet for discharge.
隨著過濾工況持續(xù)，積聚在濾筒外表面上的粉塵將越積越多，相應(yīng)就會增加設(shè)備的運行阻力，為了保證系統(tǒng)的正常運行，除塵器阻力的上限超出范圍內(nèi)，由PLC脈沖自動控制器通過定阻或定時發(fā)出指令，進(jìn)行壓縮空氣脈沖噴吹清灰。
As the filtering condition continues, the dust accumulated on the outer surface of the filter cartridge will accumulate more and more, which will correspondingly increase the operating resistance of the equipment. In order to ensure the normal operation of the system, the upper limit of the resistance of the dust collector exceeds the range. The PLC pulse automatic controller sends instructions through fixed resistance or timing to carry out compressed air pulse jet cleaning.
產(chǎn)品特點:
Product features:
■ 濾筒采用聚四氟乙烯材料，表面熱覆了一層纖維膜，它可以直接將粉塵阻接在濾材的表面上；
The filter cartridge is made of polytetrafluoroethylene material, with a layer of fiber membrane coated on the surface, which can directly block the dust onto the surface of the filter material;
■ 濾料折褶使用，可增大過濾面積，并使除塵器結(jié)構(gòu)更為緊湊；
The use of filter material folding can increase the filtering area and make the structure of the dust collector more compact;
■ 與同體積除塵器相比，過濾面積相對較大，過濾風(fēng)速較小，阻力?。?/div>
Compared with the same volume dust collector, the filtering area is relatively larger, the filtering wind speed is smaller, and the resistance is small;
■ 除塵器清灰采用脈沖噴吹在線清灰方式，清灰過程由脈沖控制儀自動控制，組合式除塵器清灰采用分離式脈沖自動循環(huán)清灰。每個除塵室內(nèi)設(shè)置多個濾筒以增加其過濾面積，當(dāng)某個除塵室內(nèi)濾筒滿足清灰設(shè)定要求時，即啟動噴吹裝置進(jìn)行清灰，其他除塵室正常工作，即達(dá)到清灰目的，又保障除塵器正常運轉(zhuǎn)；
The dust collector adopts a pulse injection online dust cleaning method, and the dust cleaning process is automatically controlled by a pulse control instrument. The combined dust collector uses a separate pulse automatic cycle for dust cleaning. Each dust removal room is equipped with multiple filter cartridges to increase its filtration area. When a certain dust removal room filter cartridge meets the requirements for dust removal, the spraying device is activated for dust removal, and other dust removal rooms work normally to achieve the purpose of dust removal while ensuring the normal operation of the dust collector;
■ 除塵效率高，且設(shè)備使用壽命長。
High dust removal efficiency and long service life of the equipment.
