Problems solved by technology

[0006] 1. The flue gas at the top of the furnace is exhausted by the original smoke exhaust system, and there is residual gas above the stove. Although the residual gas is small, it also has the danger of polluting the indoor air
[0007] 2. The original heat exchanger can well exchange heat from the side wall of the furnace and the heat of the flue gas, but the waste heat at the top of the furnace is not fully utilized

Embodiment 1

[0035] Such as Figure 1-3 As shown, the fume collecting hood includes a fume collecting hood 4, the fume collecting hood 4 includes a cavity suitable for water circulation, and the side wall of the fume collecting hood 4 is provided with a fume collecting hood water inlet 41 and a fume collecting hood water outlet 43 and is connected with The cavity is connected, and the side wall of the middle part of the smoke collecting hood body 4 includes a smoke exhaust port 3 , and the cavity surrounds the smoke exhaust port 3 . The smoke exhaust outlets 3 are evenly distributed on the side wall of the middle part of the smoke collecting hood body 4, and there are three smoke exhaust outlets 3. The side wall of the smoke collecting hood 4 is also provided with a water temperature sensor 42 , an explosion-proof valve 44 and a temperature detection port 46 . An air source and air distribution pipe installation hole 45 is axially arranged at the bottom of the smoke collecting hood 4 clos...

Embodiment 2

[0037] Embodiment 2 is basically the same as Embodiment 2, except that the middle side wall of the smoke collecting hood 4 includes 2 or 4 or 5 or 6 smoke outlets.

Embodiment 3

[0039] Such as Figure 1-6 As shown, the heating device includes the aforementioned smoke collecting hood, and also includes the furnace 1 and the exhaust pipe 10, and includes the stove 30, and the top of the stove 30 is equipped with a furnace cover smoke exhaust device 33, and the furnace cover smoke exhaust device 33 includes a furnace cover The smoke exhaust cavity 331 and the side wall of the furnace cover smoke exhaust cavity 331 are provided with a furnace cover smoke exhaust interface 332 , the furnace cover smoke exhaust interface 332 is connected with a connecting pipe 34 , and the connecting pipe 34 is connected to the exhaust pipe 10 .

[0040] The cooktop 30 fits on the top of the smoke collection hood 4, and the cooktop 30 surrounds the furnace mouth 2. Below the smoke collection hood 4 are the upper air distribution device 11 and the furnace 1 in turn. The outside of the furnace 1 is a heat exchanger 14, and the heat exchanger Including the heat exchanger water...

Abstract

The invention discloses an exhaust fume collecting hood and a heating device, and belongs to the field of civil heating devices. Exhaust fume at the top of a hearth is exhausted through an original exhaust fume exhaust system, a residual gas exhaust structure is additionally arranged above a cooking bench, and the influence of the heating device on the indoor air quality is effectively eliminated through exhaust of residual gas. Waste heat at the top of the hearth of the novel heating device is fully utilized, the sealing performance is better, energy loss is reduced, the fuel utilization rate of the heating device is higher, and the heating effect is better.

Description

technical field [0001] The invention belongs to the field of civil heating devices, and in particular relates to a smoke collecting hood and a heating device. Background technique [0002] At present, civil heating furnaces mainly include electric heating furnaces, fuel gas heating furnaces, coal-fired heating furnaces, etc. Among them, coal-fired heating furnaces are economical and affordable. A coal-fired heating furnace with lower heating costs is ideal. [0003] my country has established a complete classification system for coal, including coal calorific value classification, coal phosphorus classification, sulfur classification, etc. Different classifications of coal have different combustion characteristics. There is no record in the prior art of giving different combustion-supporting methods to different coals. In the prior art, a vertical coal-fired atmospheric hot water boiler is mainly composed of a pot shell head, a furnace furnace, a furnace roof, a lower seal...
