Abstract

The invention provides a waste heat recycling type deduster which is used for recycling waste heat of high-temperature flue gases. The waste heatrecycling type deduster comprises a plurality of box bodies connected in sequence, high-temperature flue gas flow channels are formed in the box bodies, and a plurality of filter devices for filtering flue gases are vertically arranged in each high-temperature flue gas flow channel; water cooling devices are respectively arranged on the outer walls of the box bodies, and the water cooling devices on the outer walls of the box bodies exchange heat with high-temperature flue gases flowing in the box bodies, and heat recycling devices are respectively connected to the water cooling devices so as to recycle the heat generated after the heat is exchanged between the water cooling devices and the high-temperature flue gases. The waste heatrecycling type deduster not only can remove dust, but also can recycle heat in the high-temperature flue gases at the same time.

Description

technical field [0001] The invention relates to a dust collector, in particular to a waste heat recovery type dust collector capable of recovering high-temperature flue gas. Background technique [0002] The process of traditional high-temperature dusty flue gas purification and waste heat recovery system is generally: flue gas from the furnace → waste heat boiler → low-pressure pulse bag filter → dust removal fan → chimney. In the traditional high-temperature dusty flue gas purification and waste heat recovery system, the high-temperature filter material used in the low-pressure pulse bag filter is generally P84 high-temperature-resistant needle-punched felt filter material or high-temperature resistant filter material such as Fluomes. The filter materials are all fiber filter materials, and the maximum operating temperature cannot exceed 240°C. Long-term over-temperature operation will drastically shorten the service life of the filter bag, and the flue gas must not have s...
