Description
Technical field
The utility model relates to a kind of air preheater, is specifically related to a kind of air preheater for boiler.
Background technology
Air preheater main application improves the heat exchange performance of boiler, reduces energy ezpenditure.At present, air preheater can be divided into box type and swinging.The feature of box type air preheater is that principle is simple, and be easy to manufacture processing, good airproof performance, heat transfer efficiency is high, but its volume is excessive, easily piles ash in steel pipe, and be not easy to cleaning and gas approach place, these cause its life cycle short; Rotary regenerative air preheater, it utilizes flue gas and air to add hot-air alternately through metal heated, and its problem is to leak out, corrosion, and stifled ash, in order to address these problems, in design, manufacture and install on rotary regenerative air preheater, take too high budget; And all there is the problem causing fire due to air channel blocking in this two air preheater, so efficiently a in order to research and develop, safety, the air preheater of low cost is the main path improving boiler effect.
Utility model content
With regard to the defect of above prior art, the purpose of this utility model is to provide a kind of air preheater for boiler, and it is efficient, safety, production cost are low.
For solving the problems of the technologies described above, the utility model discloses a kind of air preheater for boiler, comprising body and being positioned at the PLC below body, wherein:
Body is from left to right disposed with air inlet, fan, adsorption chamber, heating clamber and air outlet;
Heating clamber comprises temperature controller, heating element and baffle plate, and baffle plate is positioned at heating clamber sidepiece, and temperature controller is arranged on top and the bottom of heating clamber, and heat-insulation layer is attached to the outside of temperature controller, and three heating elements are arranged on heating chamber uniformly.
Preferably, heating element inside is provided with PTC potsherd, and PTC potsherd quantity is 12, and every root heating element inner homogeneous arranges four.
Preferably, baffle plate comprises peg, the multiple louver board be set up in parallel and stacks drag-line, and peg is separately positioned on top and the bottom of baffle plate, stacks the top that drag-line hangs over peg, and multiple louver board is together in series by stacking drag-line.
Preferably, the top of two baffle plates 12 and bottom are respectively arranged with fastener 4.
Preferably, fastener 4 is positioned at the outside of body 9.
Adsorption chamber and heating clamber join in air preheater for boiler by the utility model, first the flue dust in air and impurity are adsorbed, pass through oven heats again, can by PLC and baffle plate during heating, ensure that the heating effect of whole heating clamber highly effective and safe, effectively prevent the problem that the irregular or heating-up temperature of air preheater heating does not reach boiler demand, and production cost is lower.
