Abstract
The utility model discloses an air preheater with spoilers. The air preheater with the spoilers comprises a box body and a sealed cavity, wherein the box body is communicated from the left side to the right side and is formed by an upper pipe plate, a lower pipe plate and two side wallboards, the cavity is formed by pipe cavities of the upper pipe plate, the lower pipe plate, a smoke inlet pipe, a smoke outlet pipe and a plurality of thin-wall steel pipes, a middle separation plate is arranged on the middle position of thin-wall steel pipes in the box body and divides the box body into an upper part and a lower part, an air outlet pipe is arranged at the upper portion of the left side of the box body, an air inlet pipe is connected with the lower part at the left side of the box body, an air communication cover is connected with the right side of the box body, the air inlet pipe, the lower part of the box body, the air communication cover, the upper part of the box body and the air inlet pipe form a complete air return path, and the spoilers are respectively arranged at the left side and the right side inside the box body, and the air inlet pipe and the air outlet pipe are respectively arranged at two sides of the air communication cover. The air preheater with the spoilers has the advantages of being simple in structure, largely improving the heat exchange efficiency, and being obvious in energy-saving and consumption-reducing effect.
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 spoiler 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, Mist heat recovering also is an important energy saving way.A kind of air preheater that the applicant applies on the same day, it tube chamber that comprises the casing of the sealing that lower perforated plate, front and back two side wall panels, left and right sides air communication cover consist of and upper lower perforated plate, flue gas inlet tube, smoke outlet tube, some thin-wall steel tubes consists of the cavity of a sealing; 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 is made lateral flow in thin-wall steel tube external space casing, 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, because there is the dead angle in air when making lateral flow in thin-wall steel tube external space casing, heat exchange is insufficient, has reduced heat exchange efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, air preheater with spoiler of significantly improving heat exchange efficiency, can saving energy and reduce the cost is provided.
The utility model is achieved by the following technical solution: with the air preheater of spoiler, 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; It is characterized in that: 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, 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; 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 comprises by upper perforated plate, lower perforated plate, two side wall panels with the air preheater of spoiler and consists 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; When 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.Because left side, right side in the casing are respectively equipped with spoiler, have increased the disturbance of air, have avoided the dead angle of Air Flow, improve heat exchanger effectiveness.
Further, the left side in the described casing, the length sum of right side spoiler be less than the length of median septum, so that air flows in casing is more abundant.
The utility model compared with prior art has following beneficial effect: simple in structure, significantly improve heat exchange efficiency, energy conservation and consumption reduction effects is obvious.
