Abstract
The utility model relates to an antiseptic wearable air pre-heater, which comprises a pre-heater main body, a tube plate, a heat exchanging pipe, a fire-resisting cement layer and a draft tube, wherein a ventilating duct is respectively arranged above and below the pre-heater main body, an air inlet and an air outlet are arranged at the middle part of the pre-heater main body, the tube plate is divided into an upper tube plate and a lower tube plate which are arranged at the inlet end and the outlet end of the ventilating duct, a plurality of heat exchanging pipes are uniformly distributed between the upper and the lower tube plates, the lower surface of the lower tube plate is provided with the fire-resisting cement layer, and one end of the air inlet of each heat exchanging pipe is welded with the draft tube. By adopting the above structure, the tube plate can bear the corrosion and erosion of multi-composition medium of the smoke gas, so the problem that the head of the heat exchanging pipe of the air pre-heater is fractured and loses effectiveness can be solved, and the service life of the air pre-heater is prolonged.
Description
Technical field
The utility model relates to a kind of air preheater, a kind of specifically anticorrosion antiwear regenerative air heater.
Background technology
With the arrival of global energy crisis, the energy-saving equipment of UTILIZATION OF VESIDUAL HEAT IN, saving coal is the important topic of every profession and trade research always.
Since many components of the flue gas that generates behind the coal combustion, the CO that burning generates
2, SO
2Do not participate in the O of combustion reaction
2, N
2, H
2O water vapour, CO and particle flue dust, corrosion to air preheater under the condition of high temperature is more serious, quickened the corrosion and the wearing and tearing of air preheater, made vitals heat exchange tube head wearing and tearing Cracking Failure in the air preheater, the service life of having reduced air preheater.
Summary of the invention
The purpose of this utility model is that a kind of simple and reasonable, the problem that there is not Cracking Failure in the heat exchanger tube tube head, the anticorrosion antiwear regenerative air heater of long service life will be provided.
The object of the present invention is achieved like this, this air preheater comprises preheater body, tube sheet, heat exchanger tube, refractory cement layer, mozzle, described preheater body upper and lower settings has ventilating duct, the centre is provided with air ports, tube sheet is divided into upper perforated plate and lower perforated plate, is set at the entrance end of ventilating duct, and a plurality of heat exchanger tubes are uniform to be arranged between the lower perforated plate, be provided with the refractory cement layer below lower perforated plate, air inlet one end of each heat exchanger tube is welded with mozzle.
The utility model is owing to adopt said structure to make tube sheet withstand the corrosion and the erosion of many components of flue gas medium, thereby solved the problem of air preheater heat exchanger tube tube head Cracking Failure, prolonged the service life of air preheater.

The specific embodiment
Shown in accompanying drawing: this air preheater comprises preheater body 1, tube sheet 2, heat exchanger tube 3, refractory cement layer 4, mozzle 5, described preheater body 1 upper and lower settings has ventilating duct 6, the centre is provided with air ports 7, tube sheet 2 is divided into upper perforated plate 2-1 and lower perforated plate 2-2, be set at the entrance end of ventilating duct 6, a plurality of heat exchanger tube 3 uniform being arranged between lower perforated plate 2-1, the 2-2, be provided with refractory cement layer 4 below lower perforated plate 2-2, air inlet one end of each heat exchanger tube 3 is welded with mozzle.
Operation principle: the flue gas (thermal medium ↑) of heat from top to bottom flows, and is flowed out by the air inlet of ventilating duct 6 through trumpet-shaped mozzle 5, heat exchanger tube 3 from the air inlet of ventilating duct 6.
Air (cold medium ←) is entered by the air air inlet, carries out being flowed out by the air air outlet after the heat exchange through the outer fin of heat exchanger tube 3 pipes.
