Description
Technical field
The utility model relates to the heat-exchange device that is used for flue gas waste heat recovery on the boiler, relates in particular to a kind of air preheater with expansion appliance for flue gas waste heat recovery.
Background technology
Because the energy is a kind of non-renewable resource, energy day is becoming tight, and the various energy saving pot type of furnaces are gradually improved, and adopts behind the high-quality insulation material so that the boiler radiation loss obviously descends; Adopt advanced burner to strengthen burning, reduced the imperfect combustion amount, it is reasonable that air-fuel ratio also is tending towards.Yet, reducing the become estranged technology of Mist heat recovering of exhaust gas heat loss still makes progress unhappy, flue gas is the main path of general energy consumption equipment waste energy at present, the smoke evacuation power consumption of boiler is greatly about about 15%, in order further to carry the thermal efficiency of boiler, reach energy-saving and cost-reducing purpose, utilizing the air preheater Mist heat recovering also is an important energy saving way.Existing a kind of air preheater mainly comprises the cavity that is made of a sealing the tube chamber of upper perforated plate, lower perforated plate, flue gas inlet tube, smoke outlet tube, some thin-wall steel tubes; Consisted of the casing that communicates about by upper perforated plate, lower perforated plate, two side wall panels; The medium position of thin-wall steel tube is provided with median septum in the described casing, casing is divided into up and down two parts, the left upper portion of described casing is divided and is connected with the air outlet slit pipe, and part is connected with the air intlet pipe under the left side of described casing, and the right side of described casing is connected with the air communication cover; Described air intlet pipe, lower box divide, part, air intlet pipe consist of a complete air loop on the air communication cover, casing; When high-temperature flue gas flows in the cavity of sealing through the Steel Thin-Wall tube chamber, flow from top to bottom, parallel baffled thin-wall steel tube cavity wall, air enters successively that air intlet pipe, lower box divide, part, air intlet pipe on the air communication cover, casing, in thin-wall steel tube external space casing, flow, wash away outer wall, thereby make flue gas and air carry out heat exchange at Steel Thin-Wall tube wall place, air enters the further work environment after obtaining heating.The problem of its existence is, high-temperature flue gas is not stopped to have entered in the flue gas inlet tube the inside, and flue gas inlet tube is heated, and its swell increment is larger, flue gas inlet tube is fragile, and after flue gas inlet tube damaged, flue gas was excessive, serious environment pollution not only, damage equipment, and reduced heat exchange efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, solved flue gas inlet tube free wxpansion, prevented device damage, the air preheater with expansion appliance that increases the service life.
The utility model is achieved by the following technical solution: with the air preheater of expansion appliance, comprise by upper perforated plate, lower perforated plate, two side wall panels consisting of the casing that communicates about; Consisted of the cavity of a sealing by the tube chamber of upper perforated plate, lower perforated plate, flue gas inlet tube, smoke outlet tube, some thin-wall steel tubes; The medium position of thin-wall steel tube is provided with median septum in the described casing, casing is divided into up and down two parts, the left upper portion of described casing is arranged with the air outlet slit pipe, and part is connected with the air intlet pipe under the left side of described casing, and the right side of described casing is connected with the air communication cover; Described air intlet pipe, lower box divide, part, air intlet pipe consist of a complete air loop on the air communication cover, casing; It is characterized in that: described flue gas inlet tube is provided with expansion appliance.
Left side, right side in the described casing are respectively equipped with spoiler.
Left side in the described casing, the length sum of right side spoiler are less than the length of median septum.
The utility model owing to be provided with expansion appliance at flue gas inlet tube, has solved flue gas inlet tube free wxpansion with the air preheater of expansion appliance, has prevented the problem of device damage.
The utility model compared with prior art has following beneficial effect: simple in structure, flue gas inlet tube can free wxpansion, prevent from device damage from increasing the service life.
