Description

A kind of self-cleaning high-performance forces cold wind blower

Technical field

Energy-conserving and environment-protective technical fiel is the utility model is related to, specially a kind of self-cleaning high-performance forces cold wind blower.

Background technology

Quenching device is forced in various stove dust pelletizing systems, is used as high-temperature flue gas cooling, and current Generally used in domestic high temperature fume dust removal system, but find problems be present in use for many years：1. cooler Heat-exchanging part fume side is easier dust stratification, causes deashing frequent, and working strength is high；2. because equipment is huge, heat transfer area Greatly, the heat transfer coefficient of cooling device can not be further enhanced, and these problems not only increase investment and operating cost, also make The about development of dedusting technology.

The content of the invention

In view of the above-mentioned problems, the utility model, which provides a kind of self-cleaning high-performance, forces cold wind blower, it can be effective The dust stratification of heat-exchanging part fume side is prevented, and greatly improves heat transfer coefficient, investment reduction and operating cost.

Its technical scheme is such：It includes hollow housing, it is characterised in that it is included by upper header, screwed pipe Exhaust gases passes that beam, lower collecting box are linked in sequence, by axial flow blower, the housing and the screwed pipe bundle with being arranged in juxtaposition in it Between the cooling duct that is linked in sequence of the lateral outlet of space and housing, the upper header is provided with smoke inlet, the second line of a couplet Case is provided with exhanst gas outlet, in the lower section of the exhaust gases passes, the bottom connection ash bucket of the lower collecting box.

It is further characterized by, and in enclosure interior, the flue gas flow direction and cooling airflow are to vertical；

The axial flow blower has 3, is arranged in juxtaposition along the bar length direction of the screwed pipe bundle.

The beneficial effects of the utility model are that it uses heat exchanger components of the screwed pipe bundle as cooling device, and pipe is outer to be passed through Axial flow blower is forced to be blown into air, so as to carry out heat exchange with cooled flue gas；And in the flue gas of Bottomhole pressure, by spiral groove Guiding, part of smoke crossheading inside pipe wall face rotated, and another part flue gas is axially moved along wall, and helical structure makes Flue gas produces periodically disturbance, so as to not only be thinned the boundary layer of fluid, can cause disturbing for fluid particle in boundary layer again It is dynamic, accelerate by the heat transfer of wall to bodies of fluid, improve heat transfer coefficient, saved investment cost；And to wall Strong souring and due to outside pipe cooling air expand with heat and contract with cold the telescopic action with screwed pipe, shape is difficult on wall Into dust layer, dust stratification is effectively prevent, so as to reduce flue gas collateral resistance, reduces operating cost；Simultaneously because flue gas is downward Strength rotates, and part flue dust can fall into bottom ash bucket under inertia force effect, effectively play dustproof function.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the A-A profiles in Fig. 1.

Embodiment

As depicted in figs. 1 and 2, the utility model includes hollow housing 6, its also include by upper header 2, screwed pipe bundle, Exhaust gases passes that lower collecting box 4 is linked in sequence, by empty between axial flow blower 1, housing 6 and the screwed pipe bundle with being arranged in juxtaposition in it Between and housing 6 the cooling duct that is linked in sequence of lateral outlet, the heat exchanger tube for forming screwed pipe bundle is screwed pipe 3, and with just Square in-line arrangement is arranged in juxtaposition；Upper header 2 is used as flue gas shunting；Lower collecting box 4 is used as flue gas and confluxed；Upper header 2 is provided with flue gas and entered Mouthful, lower collecting box 4 is provided with exhanst gas outlet, in the lower section of exhaust gases passes, the bottom connection ash bucket 5 of lower collecting box 4；Inside housing 6, Flue gas flow direction and cooling airflow are to vertical；Axial flow blower 1 has 3, and the bar length direction threadingly restrained is arranged in juxtaposition.

Utility model works process is that flue gas enters upper header 2 by the smoke inlet of upper header 2, and then flue gas shunting enters Enter number screwed pipe 3 in terms of ten ~ hundred, lead to flue gas in pipe, flue gas flows, guided by spiral groove, one from top to bottom in pipe Partial fume crossheading inside pipe wall face is rotated, and another part flue gas is axially moved along wall, and helical structure produces flue gas Periodically disturbance, so as to not only be thinned the boundary layer of fluid, the disturbance of fluid particle in boundary layer can be caused again, accelerated By the heat transfer of wall to bodies of fluid, heat transfer coefficient is improved, saves material, has saved investment cost；And to wall The strong souring in face and because helicitic texture and the outer cooling air of pipe expand with heat and contract with cold the flexible work with screwed pipe 3 With being difficult to form dust layer on wall, effectively prevent dust stratification, so as to reduce flue gas collateral resistance, reduce operating cost； Axial flow blower 1 introduces cooling air, and forces the passage between blowing into outside screwed pipe 3 by axial flow blower 1, in screwed pipe 3 Flue gas carries out indirect heat exchange by the tube wall of screwed pipe 3, and flue-gas temperature, which reduces, to be cooled, and the flue gas after cooling enters lower collecting box 4 After collecting, discharged by the exhanst gas outlet of lower collecting box 4；And because flue gas strongly rotates downwards, effect of the part flue dust in inertia force It is lower to be separated with flue gas, bottom ash bucket 5 is fallen into by lower collecting box 4, periodically discharge, has effectively played dustproof function.
