Background
Common dust pelletizing system all is that the soot blowing system adds defeated grey system and constitutes, and theory of operation is when the flue gas flows through the heat exchanger, because heat exchanger cross sectional dimension grow and heat exchanger resistance reason itself lead to the flue gas velocity of flow to reduce, and the dust in the flue gas can be attached to the finned tube surface or fall in the heat exchanger bottom under the action of gravity, the heat transfer effect of greatly reduced heat exchanger to can cause whole flue gas system resistance increase. The principle of the soot blowing system is that when dust in flue gas is attached to the surface of the finned tube, the soot blowing system blows the soot attached to the surface of the finned tube into a soot hopper at the bottom of the heat exchanger through a steam soot blower or a sound wave soot blower, and then the soot is conveyed into a soot tank through a soot conveying system below the soot hopper. The traditional dust removal system has the defects that the heat exchanger is cleaned through the dust blower after dust is accumulated, the purging difficulty is increased by purging after the dust is accumulated, the purging cannot be performed once, and the dust can be accumulated continuously until the heat exchanger is blocked.

The utility model discloses a finned tube heat exchanger dust pelletizing system for stirling engine group, prior art compares produced beneficial effect and is:
1) compared with the traditional soot blowing system and the soot conveying system, the dust removing system designed by the invention can effectively prevent dust from attaching to the surface of the finned tube and depositing at the bottom of the heat exchanger instead of removing the dust after the dust is deposited on the heat exchanger, and can better prevent the dust from being deposited on the heat exchanger.
2) The hot air generated by the air preheater is used for blowing, the heat exchange tube can be prevented from being damaged by the overlarge temperature difference of cold air directly, and the air preheater in the original system is utilized, so that the cost is saved.
3) The heat exchanger ash removal system is simple, the number of equipment is small, the maintenance is simple, the investment cost is low, no steam is consumed, no power consumption equipment is added, and the operation and maintenance cost is low.
