Description

Technical Field

[0001] The utility model relates to the technical field of boiler dust collectors, in particular to a boiler dust collector capable of recovering waste heat. Background Art

[0002] Boiler dust collector is a device used to remove particulate matter from boiler flue gas. It is usually used in industrial boilers or power plants to reduce the impact of flue gas emissions on the environment. Its working principle is to capture particulate matter in flue gas through physical or chemical methods to purify the flue gas. Common dust removal technologies include electrostatic precipitator, bag filter, wet dust removal, etc.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN205391984U discloses a biomass boiler flue gas dust collector, which belongs to the field of boiler dust collectors. The sides of the dust removal chamber are respectively connected to the preheating chamber for inputting boiler flue gas and the heat exchange chamber for outputting flue gas. A multi-return heat exchange tube bundle is arranged inside the preheating chamber, and a finned heat exchange tube is arranged inside the heat exchange chamber. Compared with the prior art, the utility model is a preheating dust removal device that organically integrates the auxiliary equipment of the biomass boiler, rationally utilizes the space, reduces the system resistance, and adds a finned heat exchanger behind the dust collector to maximize the use of flue gas heat. In order to achieve the effects of improving combustion efficiency, saving fuel, protecting bags, and making full use of the heat of flue gas. The heat exchange of the air preheater is used to reduce the temperature of the flue gas entering the bag filter, effectively protecting the bag from being easily scalded by high-temperature flue gas.

Secondly, there may be certain errors when installing the boiler dust collector pipe, resulting in the inability to accurately connect the two pipes, which will greatly affect the efficiency of the dust collector pipe docking and is more troublesome to use.
