Bidirectional environment-friendly energy saving boiler with three return strokes

Abstract

The invention relates to a bidirectional environment-friendly energy saving boiler with three return strokes, which comprises a boiler body, an inner water jacket and an outer water jacket, wherein a heat collecting plate and a heat collecting tube are extended at the upper part of the inner water jacket; a heat collecting tube is additionally installed in a bent flue; and a dust falling chamber and a dust removing door are arranged at the lower part of a flame outlet. In the invention, combustion chambers of the bidirectional environment-friendly energy saving boiler with three return strokes comprise a reverse combustion chamber and a secondary combustion chamber, and a double-layer water tube grate is arranged below the reverse combustion chamber, thereby having larger heat absorption capacity and fastest heat energy transmission. The invention has the advantages that the flue with three return strokes is used, thus the flue is lengthened in the boiler body so as to be convenient for heating the heat collecting plate and the heat collecting tube; and in addition, the flame in the reverse combustion chamber goes downwards from the gap of the first layer of the double-layer water tube grate, and the tongue of flame directly goes to the second layer of the water tube grate, so the boiler has high heating speed and more heat utilization, saves coal by more than 45%, and can burn industrial and household garbage. The boiler of the invention can be widely applied to large factories and mines, organizations, districts and hotels for heating and bathing. Thus, the boiler of the invention is ideal equipment for meeting the current national requirements of energy saving and emission reduction.

Description

technical field

[0001] The invention belongs to a bituminous coal-fired boiler, in particular to a two-way three-pass environment-friendly and energy-saving boiler and a tea bath boiler. Background technique

[0002] At present, conventional coal-fired boilers are still used in heating and tea bath furnaces in most areas, and the structure is unreasonable, resulting in insufficient combustion, insufficient use of heat energy, and poor thermal efficiency. Combustibles and heat are discharged into the atmosphere, resulting in waste of energy. Bad situation of polluted air. Contents of the invention

[0003] The purpose of the present invention is to propose a new technical solution for the above problems, a two-way three-pass environmental protection and energy-saving boiler.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0005] The two-way three-pass environmental protection and energy-saving boiler is ...

Examples

Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0008] A two-way three-pass environmental protection and energy-saving boiler, such as figure 1 As shown, it includes the furnace body 14 composed of the outer water jacket 3 and the inner and outer cylinders, and an inner water jacket 4 is added in the furnace body 14. The inner water jacket 4 is divided into upper and lower parts, both of which are composed of an inner layer and an inner layer. The outer layer is composed of a coal charging door 15 in the lower part. Bituminous coal and combustible garbage are fed through the coal charging door 15 and enter the anti-burning chamber 16. Since the upper part of the anti-burning chamber is not connected with the chimney, it depends on the suction of the chimney outside. The burning flame burns downwards, and double-layer water tube furnace grates are arranged below the counter-burning chamber, t...
