Abstract
Disclosed is a film and wall desulfurizing heat exchanger used in flue gas desulfurization. A wing panel is arranged outside a seamless steel tube and along an axle, and is connected with a neighboring steel tube. A bundle of seamless steel tubes is connected with the wing panel to form a film wall along a steel tube axle. The bundle of seamless steel tubes can be arranged in parallel, staggered, or in sequence. The ratio of the lateral space S1 between seamless steel tubes versus the external diameter (d) of a seamless steel tube equals to 2.0 to 3.0; the ratio of the vertical space S2 versus the external diameter (d) of the seamless steel tube equals to 1.0 to 2.0; the ratio of (d) of the seamless steel tube versus the thickness (t) of the wing panel equals to 9.5 to 16. Since dust is unsusceptible to deposit on the film wall, the corrosion of seamless tubes and the wing panel is greatly slowed down. Consequently, the ventilation resistance is reduced and the heat transmission efficiency is strengthened.
Description
Technical field
The utility model relates to energy device, refers in particular to a kind of membrane type wall type desulfurization heat exchanger that is used for flue gas desulfur device.
Background technology
At present, along with the continuous reinforcement of environmental requirement, thermal power plant and boiler equipment all have dust-removing desulfurating apparatus.The desulfur technology of existing extensive use is lime stone (lime) gypsum wet flue gas desulfurizing method, and the cooling heat exchanger in order to reduce flue-gas temperature before the desulfurization is one of key equipment wherein, and its general spiral-finned tube that adopts is made heat exchange element now.Because the thermograde of heat exchanger is big, and heat exchanger exit place cigarette temperature has been lower than the dew-point temperature of flue gas, a large amount of SO
2And SO
3Easily form sulfuric acid, thereby form cement-like material, spiral-finned tube is blocked based on calcium sulfate with flying dust in the flue gas in the tube bank surface condensation, very difficult during cleaning, dust stratification causes heat transfer resistance sharply to increase simultaneously, and flowing resistance increases, and has quickened the corrosion of tube wall.
Summary of the invention
The purpose of this utility model is that a kind of heat transfer efficiency height will be provided, the membrane type wall type desulfurization heat exchanger of job stability and good endurance.
Its objective is such realization:
It has seamless steel pipe, it is characterized in that the seamless steel pipe outer is axially arranged with the fin that connects adjacent steel pipe, the seamless steel pipe bundle with fin link to each other form along steel shaft to membrane wall.
Seamless steel pipe Shu Caiyong is arranged in parallel, stagger arrangement, all can along row.Horizontal spacing S between seamless steel pipe
1Equal 2.0～3.0, longitudinal pitch S with the ratio of seamless steel pipe outside diameter d
2Equal 1.2～2.0 with the ratio of seamless steel pipe outside diameter d, seamless steel pipe d equals 9.5～16 with the ratio of the thickness t of fin.
Advantage of the present utility model is to adopt seamless steel pipe to link to each other with longitudinal fin and forms membrane wall structure, in the time of can guaranteeing when heat exchanger is worked the passage between wet every layer of membrane wall of dirt airflow passes, wet ash does not have obvious stagnant wake at the seamless steel pipe afterbody, therefore, wet ash is difficult for amassing on tube wall, but is taken away by the air-flow of certain flow rate.Heat exchanger is owing to be difficult for dust stratification like this, and the corrosion that has slowed down seamless steel pipe and fin has greatly reduced flowing resistance, has strengthened heat transfer efficiency.
