Abstract

The invention discloses a flue gas deep dedusting and filtering device for a coal boiler, and belongs to the field of dedusting and filtering equipment. The flue gas deep dedusting and filtering device for a coal boiler includes a base, and telescopic sleeves are fixed to the four corners of the top of the base correspondingly. A supporting plate is arranged above the base. The tops of the telescopic sleeves are fixedly connected with the bottom of the supporting plate. The outer side of each telescopic sleeve is sleeved with a first spring, and the two ends of each first spring are fixedly connected with the top of the base and the bottom of the supporting plate correspondingly. Fixing plates are symmetrically fixed to the top of the base, second springs are symmetrically fixed to one side walls of the fixing plates, and sliding plates are symmetrically connected to the top of the base in a sliding mode. The device is good in damping effect, so that a good protection effect can be achieved in the transportation process. When a stainless steel filter screen plate is blocked, dredging can be conducted conveniently and rapidly. A heat energy recovery function is achieved.

Description

technical field [0001] The invention relates to the technical field of dust removal and filtration equipment, in particular to a deep dust removal and filtration device for flue gas used in coal boilers. Background technique [0002] When the coal boiler is burning, it will produce flue gas, which contains dust, sulfur dioxide, nitrogen dioxide and other harmful gases, so it will cause great pollution to the environment. In order to reduce environmental pollution, flue gas is usually used Dust filter device. [0003] However, the use effect of the current flue gas dust removal and filtering device is poor, and the filter plate is prone to clogging, and the current flue gas dust removal and filtering device does not have the function of heat energy recovery and utilization, and there will be a certain amount of heat in the flue gas. Recycling these heat will be a waste of energy, and the current flue gas dust removal and filtering device has poor shock absorption effect, and...
