Further, the filter plate is arranged in parallel with several layers, and several columns filter opening is provided on the filter plate.
By using above-mentioned technical proposal, by increasing the quantity of filter plate, layering is carried out to the flue gas of discharge, into
One step crosses the cleaning for guaranteeing the gas of discharge, and the sundries in air is avoided to be involved in exhaust fan, further reaches protection exhaust fan
Purpose.
Further, the filter opening on neighbouring two pieces of filter plates is in and is staggered.
By using above-mentioned technical proposal, filter effect is improved, further such that the cleaning gas of discharge, protection human body peace
Entirely.
Further, the one end of the air inlet pipe far from installs case is in horn-like.
By using above-mentioned technical proposal, air inlet pipe is open at one end in horn-like, increases contact of the air inlet pipe with flue gas
Area facilitates collection flue gas to be discharged.
Further, semicircular pull ring is provided in the maintenance door.
By using above-mentioned technical proposal, staff is facilitated to open maintenance door, replaces bag dust filter.
In conclusion the utility model has the following beneficial effects:
1, fume extractor is installed, a large amount of flue gases can be discharged, excessive harmful smoke is sucked when escape personnel being avoided to escape, is protected
Hinder human-body safety；
2, containing the gases such as sulfur dioxide, installation bag dust filter and filter plate and in bag dust filter in the flue gas generated due to burning
The substances such as interior placement milk of lime can carry out desulfurization process to flue gas, so that the sulfur dioxide in flue gas content of discharge reduces, protection
Environment and human-body safety.
