Qingdao Zhida environmental protection smelting equipment limited company was founded in August 1990, is a collection of scientific research, production and sales in one of the high-tech enterprises, the company mainly produces “melting plant equipment, waste heat and pressure utilization device, environmental protection dust removal equipment, post-furnace feeding equipment, pouring equipment and rock (mine) cotton equipment” and other products. Products are sold well throughout the country and many Asian countries (India, Pakistan, Vietnam, Russia, etc.). Our company has rich experience in non-standard design, installation, commissioning and operation management of dust removal equipment. We have a unique opinion on dust and exhaust gas treatment in foundry workshops. We have manufactured or supported dust removal equipment for hundreds of projects of nearly 100 enterprises nationwide, and have won wide praise from users. 02 Product features: 1.02 Reasonably calculate the air volume and filtration area according to the working conditions to ensure the compact structure of the box. Ensure long service life, stable and reliable operation, and convenient maintenance. 2.02 The flue gas collection method is the whole process of collection. The flue gas capture rate is > 98% m, the dust removal efficiency is > 99%, and the dust emission concentration is ≤10mg/m3. 3.02 The overall sealing performance is high, the pipeline layout is reasonable, and the pressure loss during the dust removal process is low. 4.02 The PLC control pulse valve is used for offline pulse cleaning. The cleaning cycle is confirmed according to the resistance value of the system, which avoids the wear of the filter bag by frequent ash cleaning, and reduces the overall energy consumption. 5.02 fan room noise <80dB.
