Energy-saving boiler capable of rapidly settling dust

Abstract

The invention discloses an energy-saving boiler capable of rapidly settling dust. The energy-saving boiler comprises a boiler body; a boiler flue is arranged in the boiler body; the upper end of the boiler flue communicates with an air filter chamber; the end, away from the boiler flue, of the air filter chamber communicates with multiple air pipes; the respective ends, away from the air filter chamber, of all the air pipes jointly communicate with a discharge pipe, and the discharge pipe penetrates through the boiler body and communicates with the outside; a filter screen is arranged at the communicating position of the air filter chamber and the boiler flue; the inner wall of the air filter chamber is fixedly connected with two first supports; the two first supports are jointly connectedwith a first rotating shaft rotationally; the end, adjacent to the filter screen, of the first rotating shaft is fixedly sleeved and connected with an impeller; the middle part of the first rotatingshaft is further fixedly sleeved and connected with a first bevel gear; and the upper end and the lower end of the first bevel gear are each engaged with a second bevel gear. The energy-saving boilerhas the advantages that not only can a large amount of dust be prevented from adhering to the inner walls of the air pipes, but also smooth circulation of hot air can be guaranteed, and accordingly, the utilization efficiency of heat energy is higher, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of boiler energy saving, in particular to an energy-saving boiler capable of rapidly reducing dust. Background technique [0002] Nowadays, many factories still use boilers to heat water. In the process of boiling water, coal or natural gas energy raw materials are fed into the furnace for combustion. The heat is transferred to the water in the boiler through the furnace, and then the water in the boiler for heating. The fuel will produce carbon dioxide during the combustion process, and a large amount of heat will be taken away in the process of exhausting the air containing a large amount of carbon dioxide. In order to increase the utilization efficiency of heat, some existing boilers are also equipped with multiple gas pipes. The air pipe is located inside the boiler and directly contacts the water. When the hot air is discharged through the air pipe, the heat carried by itself can also be directly trans...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that raw materials such as coal will produce a large amount of dust during the combustion process in the prior art, and these dusts will easily adhere to the inner wall of the air pipe after entering the air pipe with hot air, reducing the heat conduction efficiency in the air pipe, thereby Due to the problem of reducing the heat utilization rate, an energy-saving boiler that can quickly reduce dust is proposed
