Problems solved by technology

[0002] In thermal energy boilers with gas and biomass fuels as raw materials, the waste heat of the flue gas is generally at 200-300°C. In order to collect this part of energy, many flue gas waste heat recovery and dust removal devices have appeared, but most of them have unreasonable structures, resulting in The recycling efficiency is not high; in addition, the soot in the flue gas is one of the main causes of smog

Abstract

The invention discloses a flue gas waste heat recovery and dust removal device. A plurality of heat exchange pipes are adopted to absorb the waste heat of the flue gas of a boiler, and then the cold flue gas enters the bottom of a dust removal chamber; a spray device in the dust removal chamber is used for removing the dust of the flue gas; after that, dust-free gas is discharged outside from an exhaust hole arranged at the upper part of the dust removal chamber; sewage is discharged into a sewage settling tank from a sewage outlet arranged at the bottom of the dust removal chamber; clear water enters a clear water chamber under the action of a filter device and then is further treated by a water purifier, so that part of water source is provided for the spray device. The flue gas waste heat recovery and dust removal device not only is capable of fully absorbing the waste heat of the flue gas, thus achieving the aim of saving energy, but also is capable of carrying out full sedimentation on the dust and acid gas in the flue gas, thus guaranteeing the discharged gas to be colorless, odorless and very environment-friendly; the sewage used for removing the dust is recycled after being further treated, so that the water resource is saved.

Description

technical field [0001] The invention relates to a waste heat recovery device, in particular to a flue gas waste heat recovery and dust removal device. Background technique [0002] In thermal energy boilers with gas and biomass fuels as raw materials, the waste heat of the flue gas is generally at 200-300°C. In order to collect this part of energy, many flue gas waste heat recovery and dust removal devices have appeared, but most of them have unreasonable structures, resulting in The recycling efficiency is not high; in addition, the soot in the flue gas is one of the main causes of smog. Contents of the invention [0003] The object of the present invention is to provide a flue gas waste heat recovery and dust removal device to solve the problems raised in the background technology above. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A flue gas waste heat recovery and dust removal device, including a sew...
