How to remove dust from the foundry? In the foundry, a large amount of flue gas is generated when the box is dropped, the sand is returned to the conveyor, and the unloading is carried out. The old sand bucket is used for unloading, the old sand is screened, cooled, and lifted into the warehouse. Dust, if these flue dust adhere to the wall of the tube in the cold, it will be difficult to clean up, so how to remove dust from the foundry?
How to remove dust from the foundry? 、 分散治理法方案 Method 1.Decentralized governance law scheme
The solution of the decentralized treatment method is to directly process, collect, and filter the source point of foundry soot dust, and the purification effect is good. The dust industry and dust removal method of the foundry industry must be comprehensively treated. In order to prevent mutual pollution between the various industrial departments, it is necessary to have a solution for each production process that generates dust and exhaust gas.
The sand-mixing process, cupola smelting process, mechanical vibration sand-falling process, and artificial sand-clearing process, which are relatively easy to produce dust, should adopt strict dust-proof and dust-removal measures.
Appropriate equipment and processes for the recovery and regeneration of used sand during the production process, cleaning processes and equipment for unpacking, sand removal, and shot blasting casting, and transportation, collection processes and equipment of raw materials and waste sand should be configured Dust and dust removal measures.
How to remove dust from the foundry? Method 1.Comprehensive governance law
The comprehensive treatment method adopts the layered air supply technology, and the treatment scheme is effective, not affected by the process size, and the overall plant environment can be effectively improved.
In the non-concentrated casting workshop, the overall treatment method can be used for dust removal and ventilation, and the resin sand production core workshop and the resin sand core storeroom. Due to the requirements of process conditions, the overall treatment method can be used to control temperature, humidity, dust and odor.
How to remove dust from the foundry? Method 3: Treatment plan of bag filter
、 布袋除尘器铸造厂除尘效率可高 达到 98% 以上； 1. The dust removal efficiency of the baghouse dust collector foundry can reach more than 98% ;
、从粉尘产生，到粉尘收集，只需一套完整的设备 2. From dust generation to dust collection, only a complete set of equipment is needed
、全自动的清灰系统 3.Automatic ash cleaning system
、通风管道布局合理、美观 4. Reasonable and beautiful layout of ventilation ducts
、处理后的气体能直接排放 5.The treated gas can be directly discharged
、能够通过环保局的检测． 6 , can pass the test of the Environmental Protection Agency.
Working principle of bag filter:
的气体从管道进入灰斗上部进风口里面，在风机的引力下 ，铸造厂烟气 气体朝上流动，比较大的粉尘 颗粒 在惯性力的原理下掉落到灰斗下面。 Casting and falling sand in the foundry, returning sand conveying, unloading, old sand bucket lifting and unloading, old sand screening, cooling, lifting and storage, soot and gas generated from sand mixing and pulverized coal combustion enter the upper part of the ash bucket through the pipeline and enter Inside the tuyere, under the gravity of the fan , the foundry smoke gas flows upward, and the relatively large dust particles fall below the ash bucket under the principle of inertial force. 烟气 粉尘的气体进入中箱体被滤袋隔离，粉尘被隔离在滤袋的表面处，隔离后的干净的气体由滤袋的出口处进入上箱体，最后从风机上面的消声器排出 。 The gas with smoke and dust enters the middle box and is isolated by the filter bag. The dust is isolated at the surface of the filter bag. The isolated clean gas enters the upper box from the outlet of the filter bag and is finally discharged from the muffler above the fan. .
