Problems solved by technology

However, this heating method will easily form scale on the inner wall of the heating tube, which will greatly affect the heating efficiency after long-term use
The flue gas used for heating also contains a large amount of dust, which is easy to adhere to the outer wall of the heating pipe or the flue, which will also affect the heating efficiency

Embodiment

[0029]SeeFigure 1-3, A flue waste heat recovery heater, comprising a box body 1, four legs 2 are fixedly connected to the bottom end of the box body 1, and the bottom ends of the four legs 2 are fixedly connected to a support 31, The bottom end of the seat 31 is fixedly connected with an anti-skid pad 32. The four supports 31 increase the contact area of ​​the leg 2 with the ground. The anti-skid pad 32 increases the friction between the leg 2 and the ground to improve the stability of the heater. The front end of the box 1 is provided with a square groove penetrating the inside of the box 1, and the inside of the square groove is fixedly connected with a transparent baffle 35. The transparent baffle 35 facilitates the observation of the inside of the box 1. The top end of the top plate 3 is fixedly connected with the top plate 3 by screws, and the bottom end of the top plate 3 is fixedly connected with a sealing ring 29, and the bottom end of the sealing ring 29 contacts the top en...

Abstract

The invention relates to the technical field of waste heat recovery heaters, in particular to a flue waste heat recovery heater which comprises a box body. A heat dissipation barrel is arranged in thebox body, an air pipe network is arranged in the heat dissipation barrel, the air inlet end of the air pipe network is connected with a filter box, one side of the filter box communicates with an airblower, and a first scraper and a second scraper are rotationally arranged in the box body and make contact with the outer wall and the inner wall of the heat dissipation barrel correspondingly. According to the flue waste heat recovery heater, heat carried by flue gas in a flue can be utilized, the utilization rate of heat energy is increased, the side walls of the heat dissipation barrel can bescraped, the heat dissipation effect of the heat dissipation barrel is improved, and the use practicability of the heat dissipation barrel is improved.

Description

Technical field[0001]The invention relates to the technical field of waste heat recovery heaters, in particular to a flue waste heat recovery heater.Background technique[0002]The distance between the large boiler and the chimney is very long, and it is necessary to add a flue between the boiler and the chimney to discharge the flue gas through the flue.[0003]The flue gas exhausted from the boiler will take away a lot of heat, and a lot of heat will be discharged into the air, causing a large amount of heat loss and waste of energy.[0004]Chinese patent CN201672653U discloses a flue waste heat recovery heater, which includes a shell, a heating tube and a wind pipe; the shell is a water jacket sandwich, with inlet and outlet ports at the upper and lower ends; the shell is built with heating tubes and heating tubes The heating tube communicates with the water jacket interlayer of the shell; the air tube is semi-circular with holes on the inner tube wall and is placed between the shell a...
