Abstract
The invention relates to a smoke recovery device for a boiler. The smoke recovery device is used for recovering waste heat of smoke in a boiler chimney. A heat insulation layer is arranged on the outer portion of the chimney to surround the chimney; a gap is reserved between the heat insulation layer and the chimney; and a heat exchange cavity is formed by the gap. A heat exchange water pipe is a spiral pipe coiled on the outer wall of the chimney; the cross section of the heat exchange water pipe is a semicircle formed by an arc surface and a straight surface; and the straight surface is tightly attached to the outer wall of the chimney. According to the smoke recovery device for the boiler, the heat exchange cavity is formed in the outer portion of the chimney of the boiler, the cross section of the heat exchange water pipe is the semicircle formed by the arc surface and the straight surface, and the straight surface is tightly attached to the outer wall of the chimney, so that the heat exchange contact area between the heat exchange pipe and the chimney is increased, the heat exchange efficiency is improved, and the waste heat recycling rate of smoke is increased.
Description
Technical field
The present invention relates to waste heat recovery field, be specifically related to a kind of boiler smoke retracting device.
Background technology
Existing boiler smoke-gas residual-heat recovering device is a lot, and the heat exchanger tube of general heat exchange is cross section is circular helix tube, the water heat exchange of flue gas outside heat exchanger tube and in heat exchanger tube, the water in heating heat exchanger tube, thus the heat recovery to flue gas.Said method, heat exchange efficiency is low, and the heat recovery rate for flue gas is not high.
Summary of the invention
For solving the problem, technical problem to be solved by this invention is to provide a kind of boiler smoke retracting device.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of boiler smoke retracting device, this device is used for the recovery of fume afterheat in boiler chimney, heat-insulation layer is provided with in described chimney outside, described chimney is surrounded by described heat-insulation layer, and leave gap between described heat-insulation layer and described chimney, this gap forms heat exchanging chamber;
Be provided with intake antrum on described heat exchanging chamber top, at described heat exchanging chamber bottom water chamber, in described heat exchanging chamber, be also provided with described heat exchanging water pipe, described heat exchanging water pipe connects described intake antrum and described water chamber;
Described heat exchanging water pipe is the spiral coil being coiled in chimney outer wall, and the cross section of described heat exchanging water pipe is arc surface and faces the semicircle of composition directly, described in face directly and be close to described chimney outer wall.
Further, described intake antrum is provided with water inlet.
Further, described water chamber is provided with delivery port.
Further, described heat-insulation layer is that the insulating brick of perlite material is built into.
The invention has the beneficial effects as follows: a kind of boiler smoke retracting device provided by the invention, heat exchanging chamber is provided with in the outside of boiler chimney, the cross section of heat exchanging water pipe is arc surface and the semicircle facing composition directly, face directly and be close to described chimney outer wall, add the comes into heat transferring contact area of heat exchanger tube and chimney, improve heat exchange efficiency, thus improve the heat recovery rate of flue gas.
