Description

High-efficiency environmental protection and energy-saving furnace

Technical Field: The utility model relates to a stove, in particular to a civilian stove.

Background technology: At present, most civilian stoves are composed of a panel, a base, a furnace body fixedly connecting the two, a furnace core fixed in the furnace body, and a furnace bridge arranged under the furnace core. During use, because firewood and coal are often piled up at the bottom of the furnace core and block the furnace bridge, it is easy to cause insufficient oxygen supply to the furnace and lead to insufficient combustion; not only the fuel consumption is large, the waste is serious, but also the smoke pollution is large and the thermal efficiency is low. ; In addition, the traditional civil stoves must also uncover the furnace cover when adding fuel, which is troublesome and easily causes smoke to escape and pollute the environment.

Summary of the invention: In view of the above-mentioned defects in the prior art, the utility model aims to provide a high-efficiency, environment-friendly and energy-saving furnace with high thermal efficiency, fuel saving and low smoke pollution.

In order to achieve the above purpose, the utility model adopts the following technical solutions: it includes a base, a furnace body fixed on the base, a furnace core fixed in the furnace body, a flue and a panel fixed on the furnace body, a Furnace bridge at the lower port of the furnace, and ash box set under the furnace bridge; There are a number of ventilation holes; the upper port of the secondary combustion hood is fixed with a partition that divides the upper part of the furnace body into upper and lower parts. Below the partition is an oxygen supply chamber with a number of ventilation holes. Heating chamber with charging door and flue.

A water jacket is provided between the furnace body and the furnace core, and the water jacket is provided with a plurality of steam pipes that pass through the furnace core and extend into the furnace. A water cover and a safety valve are provided; a fire baffle is provided near the entrance of the flue; a heat insulation layer is provided between the furnace core and the furnace body.

Compared with the prior art, the utility model has the advantages of fuel saving, high thermal efficiency, low smoke pollution, and convenient use due to the adoption of the above-mentioned technical solution. The specific analysis is as follows:

1) Since the oxygen supply chamber and the secondary combustion hood are added on the basis of the original civilian stove, not only the oxygen supply near the upper port of the furnace core is increased, so that the combustible gas in the flue gas can be fully combusted, but also the flame more concentrated;

2) Since the fire baffle is set near the entrance of the flue, it can prolong the storage time of high-temperature flue gas and reduce the energy loss caused by heat discharge with the flue;

3) Due to the addition of the water jacket, the water vapor can chemically react with the coal or firewood in the furnace at high temperature to generate hydrogen and carbon monoxide with high combustion value, which further achieves the goals of saving fuel, improving thermal efficiency and environmental protection;

4) The charging door set on the side of the furnace not only facilitates adding fuel, but also can effectively prevent smoke from escaping.

The specific embodiment: the utility model will be further described below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1: the panel 1 is fixed on the base 15 through the furnace body 10 with an inverted convex structure, and the furnace core 12 is fixed on the lower part of the furnace body 10; The secondary combustion hood 19 of the shape structure is fixed on the upper port of the furnace core 12, and the upper port of the secondary combustion hood is provided with a dividing plate 4 which divides the upper section of the furnace body 10 into upper and lower parts. The area is the heating chamber 2, and the lower half area of the partition is the oxygen supply chamber 3; Corresponding to the bottom position of the oxygen supply chamber 3, there are several ventilation holes 18 communicating with the outside world. A push-pull movable furnace bridge 14 is provided at the lower port of the furnace core 12, and the bottom of the furnace bridge is fixed on the base 15. The ash box frame, the drawer-type ash box 13 is set on the ash box frame; controlling the opening of the ash box 13 can adjust the oxygen supply into the furnace, and then realize the control of the firepower. In order to enhance the combustion effect, in the furnace A water jacket 17 is provided between the body 10 and the furnace core 12, and the water jacket is provided with a plurality of steam pipes 16 that pass through the furnace core 12 and extend upward into the furnace in a spiral arrangement, and a water supply pipe arranged on the water jacket. 9 protrudes outward through the furnace body 10; in order to ensure safety, a water cover 7 and a safety valve 8 are provided on the water supply pipe 9. In order to prolong the time of high-temperature flue gas storage in the furnace and reduce the loss of heat with the flue discharge To cause energy loss, a fire baffle plate 5 is provided near the entrance of the flue 6; in order to reduce heat loss through the furnace body, a heat insulation layer 11 formed of thermal insulation material is filled between the furnace core 12 and the furnace body 10.
