Environmental protection energy-saving smokeless furnace

Abstract

The invention discloses an environment-protective energy-conversation smokeless furnace, aiming at solving the problems of the high combustion expenses, insufficient combustion and environment pollution caused by discharged harmful substances, and low combustion efficiency and not meeting needed temperature and a large amount of harmful gas and smoke and dust discharging, all of which are caused by a conventional furnace employing flammable wastes as fuels, which does not meet the environmental protection. The invention comprises: a furnace body (1), a feeding mouth (2) arranged on a furnace wall of the furnace body (1), an ash discharging mouth (7) and a smoke discharging mouth (3); the furnace body (1) is connected with a wind box (9) with a fan (10), a group of wind channels (4) are evenly distributed around the peripheral line of the furnace wall of the furnace body (1), and one ends of the wind channels (4) are communicated with the wind box (9); each wind channel (4) is internally provided with a group of wind holes (5) communicated with a furnace cavity. The invention is characterized by high efficiency and energy conversation, and smokeless, dustless and environment protective, which can be widely applied to shell shaped boilers, environment protective boilers, warm wind furnaces, and drying furnaces and so on; and also can be applied to rural household cookers, outdoor heating or field heating, etc.

Description

Technical field: [0001] The invention relates to a combustion furnace, in particular to a smokeless combustion furnace using raw coal or combustible waste as fuel. The combustion furnace is suitable for shell-shaped boilers, environmental protection boilers, heaters and drying furnaces, and can also be used as rural household stoves, outdoor heating or field heating. Background technique: [0002] At present, raw coal is the main fuel for combustion furnaces. Since raw coal is a non-renewable resource, the price is also rising. Moreover, when raw coal is burned, it will produce harmful substances such as sulfur dioxide, which not only endangers human health but also pollutes the environment. At the same time, with the rapid development of society and the richness of material life, there are more and more industrial waste and domestic waste. How to make full use of these wastes and turn them into treasures has become a major problem for all countries. Due to the use of combu...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of conventional combustion furnaces, which use raw coal as fuel for high cost, insufficient combustion, and pollute the environment with harmful substances discharged, and use combustible waste as fuel, which has low combustion efficiency, cannot meet the required temperature, and will discharge a large amount of fuel. Harmful gas and dust, do not meet the environmental protection requirements, and provide an environmental protection and energy-saving smokeless furnace, which includes: a furnace body (1), a feed port is provided on the furnace wall of the furnace body (1) (2), ash outlet (7) and smoke outlet (3), the furnace body (1) is connected with the air box (9) with the blower (10), and the furnace wall of the furnace body (1) is A group of air ducts (4) are evenly distributed on the line, and one end of the air duct (4) communicates with the air box (9); a group of air holes (5) are arranged in each of the air ducts (4), and the air holes (5) communicated with the furnace
