Problems solved by technology

[0003] After the existing H-type fin economizer is used for a long time, dust will accumulate on the fins. The dust will affect the thermal conductivity and reduce the cleanliness. Not only that, when the temperature of the flue gas changes frequently, it will cause the H-type The feedwater temperature of the fin economizer changes frequently, and fatigue cracks occur in the metal, causing pipe bursts and reducing the service life

Embodiment Construction

[0028] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0029] like figure 1 As shown, a clean H-type fin economizer includes a conduit 1 and at least two fins 2, the conduit 1 is arranged horizontally, the fins 2 are vertically arranged, and the fins 2 are evenly distributed in On the conduit 1, the conduit 1 is provided with a cleaning mechanism and two control mechanisms, and the two control mechanisms are respectively arranged at both ends of the conduit 1;

[0030] The external equipment is connected with the conduit 1, so that the water flows into the conduit 1, absorbs the heat of the flue gas through the fins 2 and the conduit 1, and heats the water in the conduit 1, realizing the function of waste heat ut...

Abstract

The invention relates to a clean type H-shaped fin coal economizer. The clean type H-shaped fin coal economizer comprises a guide pipe and at least two fins, the guide pipe is horizontally arranged, the fins are vertically arranged, and are uniformly distributed on the guide pipe, a cleaning mechanism and two control mechanisms are arranged on the guide pipe, the two control mechanisms are arranged at the two ends of the guide pipe correspondingly, the cleaning mechanism comprises a driving assembly and at least two cleaning assemblies, the driving assembly comprises a fan blade, two connecting bearings and two driving units, each driving unit comprises a connecting plate and two supports, each control mechanism comprises a rotating disc and two control assemblies, each control assembly comprises a power unit and a friction unit, and each power unit comprises a power rod, a supporting plate, two polished rods and two connecting rods. The cleaning type H-shaped fin coal economizer has the advantages that the situation that the service life is shortened due to frequent change of the temperature is prevented through the control mechanisms, moreover, the dust removal function is achieved through the cleaning mechanism, and dust is prevented from affecting the heat conductivity.

Description

technical field [0001] The invention relates to the field of waste heat utilization equipment, in particular to a clean H-fin economizer. Background technique [0002] Waste heat utilization is the energy that is not used in energy utilization equipment under certain economic and technical conditions, that is, redundant and waste energy. Waste heat recovery and utilization is an important way to improve economy and save fuel. Among them, H-shaped fins save The coal burner is a kind of waste heat utilization equipment. The fins of the H-fin economizer are rectangular, approximately square, and its side length is about twice that of the light pipe. It is an extended heating surface. The H-fin economizer Using the flash resistance welding process, the welding seam has a high fusion rate after welding, the weld seam has high tensile strength, and has good heat conduction performance. The H-shaped finned tube can also be manufactured into a double-tube double H-shaped finned tube...
