Problems solved by technology
Induced fans are generally installed on the chimney of modern boilers. The induced fan blows into the chimney through the air duct to quickly discharge the flue gas in the chimney. The service life of the induced draft fan is reduced, and now the flue gas generally contains mechanical water. Because the flue gas contains acid, this time it will cause serious corrosion to the inner wall of the chimney, resulting in a reduction in the service life of the chimney. There will be a very violent collision between the flue gas and the inner wall of the flue, causing the flue gas to lose a lot of kinetic energy. The consumption of this type of chimney is very high. To solve the above problems, a new type of boiler chimney is needed

The invention discloses an anti-corrosion chimney for a boiler, which comprises a chimney body, a flue and an induced draft fan. An air hole is arranged on the side, and a dust-proof bump is provided on the inner wall of the chimney body at the upper end of the air hole; A flue is arranged symmetrically on both sides. The flue is composed of a horizontal section and a curved section. The horizontal section is the starting end of the flue; Rotary structure, the invention has a simple structure, can effectively solve the corrosion problem of the inner wall of the chimney, change the traditional smoke inlet method, reduce the kinetic energy loss of the flue gas, protect the induced draft fan from the intrusion of smoke and dust, and prolong the service life.
Description
technical field [0001] The invention relates to a chimney, in particular to an anti-corrosion chimney for a boiler. Background technique [0002] Boiler is a kind of equipment commonly used in industrial production. A chimney will be installed on the boiler to exhaust smoke. Induced fans are generally installed on the chimney of modern boilers. The induced fan blows into the chimney through the air duct to quickly discharge the flue gas in the chimney. The service life of the induced draft fan is reduced, and now the flue gas generally contains mechanical water. Because the flue gas contains acid, this time it will cause serious corrosion to the inner wall of the chimney, resulting in a reduction in the service life of the chimney. There will be a very violent collision between the flue gas and the inner wall of the flue, causing the flue gas to lose a lot of kinetic energy. The consumption of this type of chimney is very high. To solve the above problems, a new type of boi...
