Abstract
The utility model relates to a self-cleaning H-type fin. The self-cleaning H-type fin comprises two symmetrical single-side fins (1), and the entirety of the self-cleaning H-type fin forms an H type, wherein each single-side fin (1) is provided with a bevel (3). According to the self-cleaning H-type fin, the bevel design is adopted, and on the premise of not influencing the heat exchange efficiency of the fin pipe set, parts in which dust is easily accumulated of rear fin pipes are washed by utilizing airflow refraction generated by impacting smoke on the bevels of the H-type fin, so that the dust deposition effect of the H-type fin pipe is reduced, and the heat exchange effect is improved.
Description
Technical field
The utility model relates to a kind ofly uses fin from deashing H type finned tube, is used for present coal-fired boiler in power plant flue and processes with H type finned tube with afterheat heat exchanger.Flue gas capable of using is prone to the dust stratification place to back row's finned tube group and washes away air-flow refraction in the fin flush, improves heat exchange efficiency.
Background technology
At present, be used for coal-fired power plant's smoke gas afterheat heat exchanger and all gradually adopt H type finned tube group, this pipe group has that dust stratification is few, and the flow of flue gas resistance is little, advantage such as compact conformation, weight of equipment are light.And in H type finned tube group smoke gas afterheat heat exchanger,, form certain dust stratification easily at lee face owing to leave certain interval in the middle of two butt welding fins, influence heat exchange efficiency.
Summary of the invention
[0003] purpose of the utility model provides a kind ofly from deashing H type fin, utilizes sweep of gases in the refraction of the air-flow that on deashing H type fin, produces, and the dust stratification on the rear of tube group is washed away, and improves heat exchange efficiency.
The technical scheme of the utility model is:
A kind ofly use fin from deashing H type finned tube, comprise 2 symmetrically arranged one-sided fins, integral body is the H type, and each one-sided fin is provided with knuckle.
Said one-sided fin is provided with heat exchanger tube coupling breach.
Said knuckle is arranged on top, one-sided fin windward side.Be used to reduce H type finned tube dust stratification effect in use.
The beneficial effect of the utility model is:
Guaranteeing under the heat exchange area prerequisite, utilizing sweep of gases, the dust stratification on the rear of tube group is being washed away, improving heat exchange efficiency in the air-flow refraction that on deashing H type fin, produces.
The utility model use fin from deashing H type finned tube.It adopts the knuckle design, and under the prerequisite that does not influence finned tube group heat exchange efficiency, flue gas capable of using impacts the air-flow refraction that produces at H type fin knuckle place, back row's finned tube is prone to the dust stratification place washes away, and reduces the dust stratification effect of H type finned tube, improves the heat exchange effect.
Description of drawings
Fig. 1 is the planar structure sketch map of the utility model.
Fig. 2 is the side structure sketch map of the utility model.
Fig. 3 is the perspective view of the utility model.
Among the figure: 1 is that one-sided fin, 2 is knuckle for heat exchanger tube matees breach, 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1 to 3, a kind ofly use fin from deashing H type finned tube, comprise 2 symmetrically arranged one-sided fins 1, integral body is the H type, each one-sided fin 1 is provided with knuckle 3.
One-sided fin 1 is provided with heat exchanger tube coupling breach 2.Knuckle 3 is arranged on top, one-sided fin 1 windward side.Be used to reduce H type finned tube dust stratification effect in use.Punch press adds man-hour with the design of top, fin windward side employing knuckle.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Do not breaking away under the utility model design concept prerequisite; Common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model, and the technology contents that the utility model is asked for protection all is documented in claims.
Claims (3)
1. use fin from deashing H type finned tube for one kind, it is characterized in that comprising 2 symmetrically arranged one-sided fins (1), integral body is the H type, and each one-sided fin (1) is provided with knuckle (3).
2. according to claim 1ly use fin, it is characterized in that said one-sided fin (1) is provided with heat exchanger tube coupling breach (2) from deashing H type finned tube.
