Abstract
The utility model discloses a soot deposition avoiding heat exchanger, which comprises a first shell, a second shell and a third shell which are arranged in parallel, wherein the upper end of the first shell is provided with an air inlet, the lower end of the first shell is connected with the lower end of the second shell through a connecting pipe, the upper end of the second shell is connected with the upper end of the third shell through a connecting pipe, the lower end of the third shell is provided with an air outlet, heat exchange pipes are uniformly arranged in the first shell, the second shell and the third shell, each heat exchange pipe comprises an inner pipe and an outer pipe which are concentric, the wall of each inner pipe is provided with small spraying holes, and the outer wall of each outer pipe is coated with a high-temperature-resistant corrosion-resistant ceramic coating. Due to the adoption of vertical arrangement for the heat exchange pipes, soot is prevented from being deposited on the outer walls of the heat exchange pipes.
Description
Technical field
The utility model belongs to resource and environment field, is specifically related to one and exempts from dust stratification heat exchanger.
Background technology
Heat exchanger is one of nucleus equipment in whole consumer waste incineration system, the problem that how to solve that house refuse calorific capacity is low, ash content is high, moisture content is high, is difficult to smooth combustion is a large problem, and the temperature that improves combustion air is the place of key, and the height of heat exchanger efficiency is the core that determines combustion air temperature height.In refuse burning system, adopt at present traditional heat exchangers easily to occur heat exchanger tube internal corrosion coking, manage outer fouling phenomenon, cause heat exchanger tube heat exchange efficiency greatly to decline, have a strong impact on the normal stable burning of rubbish.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides one to exempt from dust stratification heat exchanger, because heat exchanger tube adopts vertical, has prevented that dust deposition is on heat exchanger tube outer wall.
The technical scheme that the utility model adopts is: one is exempted from dust stratification heat exchanger, comprise the first housing be arrangeding in parallel, the second housing and the 3rd housing, described the first housing upper end is provided with air inlet, the first housing lower end and the second housing lower end, the second housing upper end is all connected by tube connector with the 3rd housing upper end, the 3rd housing lower end is provided with air outlet, described the first housing, in the second housing and the 3rd housing, be evenly provided with heat exchanger tube, described heat exchanger tube comprises inner and outer tubes, inner tube and outer concentric tube, on inner tubal wall, have jet apertures, outer tube outer wall scribbles high-temperature-resistant and anti-corrosion ceramic coating.
As preferably, described the first housing, the second housing and the 3rd hull shape, consistent size.
As preferably, described air inlet is connected with the first housing and the 3rd housing by ring flange respectively with air outlet.
The beneficial effects of the utility model are: the first housing, the second housing and the 3rd housing coordinate air inlet, air outlet and tube connector, form a circulation, can carry out heat exchange repeatedly, have reached better heat transfer effect.Jet apertures on inner tubal wall is because jet velocity is high, and vertical outwards pipe inspection, has destroyed the friction layer on outer tube wall, and heat convection is strengthened.

Fig. 2 is the utility model heat exchanger tube cross-sectional view.
In figure: 1, the first housing; 2, the second housing; 3, the 3rd housing; 4, air inlet; 5, tube connector; 6, air outlet; 7, heat exchanger tube; 71, inner tube; 72, outer tube; 73, jet apertures; 74, high-temperature-resistant and anti-corrosion ceramic coating.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, one is exempted from dust stratification heat exchanger, comprise the first housing 1 be arrangeding in parallel, the second housing 2 and the 3rd housing 3, described the first housing 1 upper end is provided with air inlet 4, the first housing 1 lower end and the second housing 2 lower ends, the second housing 2 upper ends are all connected by tube connector 5 with the 3rd housing 3 upper ends, the 3rd housing 3 lower ends are provided with air outlet 6, described the first housing 1, the interior heat exchanger tube 7 that is evenly provided with of the second housing 2 and the 3rd housing 3, described heat exchanger tube 7 comprises inner tube 71 and outer tube 72, inner tube 71 is concentric with outer tube 72, on inner tube 71 walls, have jet apertures 73, outer tube 72 outer walls scribble high-temperature-resistant and anti-corrosion ceramic coating 74.As preferably, described the first housing 1, the second housing 2 and the 3rd housing 3 shapes, consistent size.As preferably, described air inlet 4 is connected with the first housing 1 and the 3rd housing 3 by ring flange respectively with air outlet 6.
The first housing 1, the second housing 2 and the 3rd housing 3 coordinate air inlet 4, air outlet 6 and tube connector 5, form a circulation, can carry out heat exchange repeatedly, have reached better heat transfer effect.Jet apertures 73 on inner tube 71 walls is because jet velocity is high, and vertically sprays to outer tube 72, destroyed the friction layer on outer tube 72 inwalls, and heat convection is strengthened.
Claims (3)
1. exempt from dust stratification heat exchanger for one kind, it is characterized in that: comprise the first housing be arrangeding in parallel, the second housing and the 3rd housing, described the first housing upper end is provided with air inlet, the first housing lower end and the second housing lower end, the second housing upper end is all connected by tube connector with the 3rd housing upper end, the 3rd housing lower end is provided with air outlet, described the first housing, in the second housing and the 3rd housing, be evenly provided with heat exchanger tube, described heat exchanger tube comprises inner and outer tubes, inner tube and outer concentric tube, on inner tubal wall, have jet apertures, outer tube outer wall scribbles high-temperature-resistant and anti-corrosion ceramic coating.
