Abstract
The utility model discloses a smoke cutting turbulence device of an ordinary pressure boiler. A spiral strip-shaped smoke turbulence belt is arranged in a high-temperature smoke tube of the boiler; smoke cutting holes are formed in the lengthways direction of the smoke turbulence belt; the high-temperature smoke tube of the boiler is spiral or a screw thread is formed in the inner surface. According to the smoke cutting turbulence device of the ordinary pressure boiler, the smoke cutting holes are utilized to cut the high-temperature smoke to form local turbulence, damage border layer at the tube wall and increase exchange time and efficient heat exchange area; meanwhile, turbolator per se is of a spiral structure, so that the high-temperature smoke is enhanced to scour the inner wall of the smoke tube, cleanness of the inner wall is kept, a traveling distance of the high-temperature smoke in the smoke tube is increased, heat exchange time is added, heat efficiency of the boiler is improved greatly, running cost is reduced, convenience is brought to the maintenance, and the service life of the boiler is prolonged.
Description
Technical field
The utility model belongs to the boiler heat exchange equipment technical field, relates to a kind of normal-pressure boiler flue gas and shears disturbing flow device.
Background technology
The smoke pipe of normal pressure fuel-oil or fuel-gas boiler design at present adopts many return structures mostly, and this structure is conducive to the thermal energy exchange of high-temperature flue gas in boiler, and the thermal efficiency increases.In actual production, Boiler smoke tube adopts the inner wall smooth pipe fitting more, and it is unobstructed that this structure is beneficial to smoke pipe, is convenient to safeguard, but due to the smoke pipe inner wall smooth, press close to the tube wall place and be easy to form boundary layer, and high-temperature flue gas time of staying in boiler is shorter, affect the thermal efficiency of boiler integral body.Improvement smoke pipe internal structure is significant to promoting the thermal efficiency, the saving energy, reduction operating cost, protection of the environment etc.
The utility model content
The purpose of this utility model is to provide a kind of normal-pressure boiler flue gas and shears disturbing flow device, has solved prior art smoke pipe inner wall smooth, press close to the tube wall place and be easy to form boundary layer, and high-temperature flue gas time of staying in boiler is shorter, affects the problem of boiler thermal output.
The technical scheme that the utility model adopts is, a kind of normal-pressure boiler flue gas is sheared disturbing flow device, is provided with flue gas flow-disturbing band in the boiler high temperature smoke pipe, and flue gas flow-disturbing band is the helix shaped strip shape.
Normal-pressure boiler flue gas of the present utility model is sheared disturbing flow device, is further characterized in that:
Vertically evenly have the flue gas shearing perforation on flue gas flow-disturbing band.
The boiler high temperature smoke pipe is set to spiral-shaped or inner surface and is provided with screw thread.
The beneficial effects of the utility model are, install flue gas flow-disturbing band in Boiler smoke tube additional, and merge and adopt the spiral smoke pipe, utilize flue gas shearing perforation cutting high-temperature flue gas, form local turbulence, destroy boundary layer, tube wall place, increase heat exchanger time and available heat exchange area; Turbolator, originally as helical structure, has increased high-temperature flue gas the smoke pipe inwall has been washed away simultaneously, keeps the inwall cleannes, increase it and walk distance and strengthen heat exchanger time the smoke pipe expert, significantly promote boiler thermal output, reduce operating cost, be convenient to safeguard the prolonged boiler life-span.
The accompanying drawing explanation
Fig. 1 is the perspective view of the flue gas flow-disturbing band in the utility model device;
Fig. 2 is the plane outspread drawing of the flue gas flow-disturbing band in the utility model device.
In figure, 1. flue gas flow-disturbing band, 2. flue gas shearing perforation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1 and Figure 2, the structure of the utility model normal-pressure boiler flue gas shearing disturbing flow device is to be included in the boiler high temperature smoke pipe and to be provided with flue gas flow-disturbing band 1; Flue gas flow-disturbing band 1 is the helix shaped strip shape, and vertically evenly has flue gas shearing perforation 2 on flue gas flow-disturbing band 1.
In addition, the boiler high temperature smoke pipe is set to spiral-shaped or inner surface and is provided with screw thread, referred to as spiral smoke pipe or threaded flue, coordinates the use of flue gas flow-disturbing band 1, and effect is better.
The operation principle of the utility model device is, high temperature flue-gas from boiler enters the spiral smoke pipe, utilizes flue gas flow-disturbing band 1 and flue gas shearing perforation 2 cutting high-temperature flue gas thereof in the spiral smoke pipe, forms local turbulence, destroy boundary layer, tube wall place, increase heat exchanger time and available heat exchange area; Flue gas flow-disturbing band 1 itself is also helical structure simultaneously; according to the air force principle; increasing high-temperature flue gas washes away the smoke pipe inwall; keep the inwall cleannes; increasing high-temperature flue gas walks distance and strengthens heat exchanger time the smoke pipe expert; significantly promote boiler thermal output, save the energy, reduce operating cost, protection of the environment, prolonged boiler life-span.
