Cam-type dust-removing energy-saving boiler smoke waste heat recovery pipeline

Abstract

The invention discloses a cam-type dust-removing energy-saving boiler smoke waste heat recovery pipeline which comprises a smoke pipeline, wherein a fixing plate is mounted at the inner left end of the smoke pipeline; a rotating shaft is mounted at the middle of the fixing plate; a rotating plate is connected with the right end of the rotating shaft; a smoke dust filtering screen is mounted at theinner middle of the smoke pipeline; a power shaft is mounted at the inner right end of the smoke pipeline; rotating cams are mounted at the middle of the power shaft; a moving plate is in contact with the left sides of the rotating cams; moving rods are connected with the left end of the moving plate; a dust removing plate is fixed at the left ends of the moving rods; a heat recovery tower communicates with the right end of the smoke pipeline; and a snakelike recovery tube is mounted in the heat recovery tower. By adoption of the cam-type dust-removing energy-saving boiler smoke waste heat recovery pipeline disclosed by the invention, smoke dust can be prevented from directly entering the heat recovery tower and being attached to the outer side of the snakelike recovery tube; the recoveryeffect of the snakelike recovery tube on waste heat in smoke can be improved; and meanwhile, the smoke dust accumulated on the smoke dust filtering screen can be removed online, the blockage to the smoke dust filtering screen can be avoided, and the recovery efficiency of the waste heat in the smoke can be further guaranteed.

Description

technical field [0001] The invention relates to the technical field of energy-saving boiler flue gas recovery, in particular to a cam-type ash cleaning and energy-saving boiler flue gas waste heat recovery pipeline. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam produced in the boiler can be directly used for industrial production and human [0003] The heat energy required for people's daily life can also be converted into mechanical energy through a steam power plant, or mechanical energy can be converted into electrical ...

AI Technical Summary

Problems solved by technology

[0005] However, the waste heat recovery pipes of the common energy-saving combustion boilers on the market all have defects: the waste heat recovery pipes in the waste heat recovery pipes will accumulate a lot of soot on the outer layer during the heat recovery process, and the waste heat utilization of the flue gas is not thorough enough, resulting in A large amount of heat in the flue gas is wasted. The existence of these problems has affected the use of waste heat recovery devices on the market and cannot meet the needs of use. Therefore, we propose a more efficient energy-saving waste heat recovery pipeline for energy-saving combustion boilers
