Description

Technical Field

[0001] The utility model belongs to the field of scattered gas collecting devices, in particular to a scattered gas collecting device for ferrosilicon casting production. Background Art

[0002] After the existing diffused gas collection device collects the collected waste gas, it still requires additional equipment to filter and treat it before it can be discharged, which greatly affects the waste gas treatment efficiency and treatment cost; when the waste gas is filtered, the density of the filter material itself is relatively large, and the waste gas flow rate is slow, which affects the waste gas treatment efficiency.

[0003] The Chinese patent publication number CN213827002U discloses a device for collecting exhaust gases during the ferrosilicon pouring process, comprising: a negative pressure main pipe, a plurality of negative pressure branch pipes, and a fume collection hood. The negative pressure main pipe is used to guide the exhaust gases generated during the ferrosilicon pouring process. One end of the negative pressure branch pipe is installed on the side of the negative pressure main pipe and is connected to the negative pressure main pipe. A plurality of fume collection hoods are arranged below the negative pressure branch pipes. An air inlet is provided on the top of the fume collection hood, and the air inlet is connected to the negative pressure branch pipe. Under the action of negative pressure, the fume generated during the ferrosilicon pouring and cooling process enters the negative pressure branch pipe from the air inlet on the top of the fume collection hood, reducing the escape of fume during the ferrosilicon pouring and cooling process, improving the fume recovery efficiency, improving the workshop environment, and ensuring the health of the operators.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] 1. Through the setting of the filter component, after the exhaust gas is generated inside the ferrosilicon blast furnace, the exhaust gas directly increases the flow rate through the booster component and enters the inside of the filter tube. The exhaust gas passes through the coarse filter to block larger particles. Then, the pollutants in the exhaust gas are adsorbed and filtered through the activated carbon layer and the filter cotton layer.

[0016] 2. Through the setting of the booster component, the negative pressure impeller rotates, so that a strong negative pressure is generated inside the hood, the exhaust gas formed above the ferrosilicon ore furnace is sucked in, and the speed at which the exhaust gas moves from the inside of the hood to the filter component is greatly increased. The exhaust gas can pass through the filter component quickly, thereby avoiding the slow exhaust gas passing speed due to the high density inside the filter component and improving the exhaust gas filtration efficiency.
