Abstract
The utility model discloses a semi-pre-mixed-type secondary combustor energy-saving device which comprises a hearth, a gas valve, an air valve and a primary combustion pipe, wherein the air valve comprises a primary air valve and a secondary air valve; the gas valve is installed on a gas inlet pipe of the primary combustion pipe; and the primary air valve is installed on the air inlet pipe of the primary combustion pipe; a flame spray nozzle of the primary combustion pipe is connected with a fuel material inlet of the hearth; and the secondary air valve is installed on the air inlet of the hearth. According to the utility model, a method that combustible gases and air are premixed and then are subjected to high-speed spraying combustion, so that a short flame with purple red outer flame is generated is adopted, and the short flame in the hearth forms rotational flow injection by the thrust of injection along fire channels of a furnace cavity and a fusion aluminum crucible, thus heat radiation energy and flue in the hearth are propelled spirally, the detention time of heat energy in the hearth is prolonged, the smoke exhaust speed and temperature are lowered, the smoke exhaust concentration and oxygen content in smoke are reduced, the energy-saving effect is much obvious, and the environment is protected.
Description
Technical field
The utility model relates to a kind of burner apparatus, relates in particular to a kind of half pre-mixing type secondary combustor energy saver.
Background technology
The potter had become one of big power consumer in China's building material industry already, and the burning kiln power consumption accounts for the over half of the sector, if add the drying equipment power consumption, then accounted for more than 70% of total energy consumption.Cause the too high major reason of above-mentioned energy consumption, adopt exactly the primary combustion device, i.e. fuel and air mixed combustion in burner hearth produces heat and is used for ceramic sintering.The defective of primary combustion is that burning is not thorough, contains many uncombusteds fuel in the flue gas of discharge, causes energy waste and environmental pollution.
Summary of the invention
The purpose of this utility model provides a kind of half pre-mixing type secondary combustor energy saver that makes the fuel second-time burning with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises burner hearth, gas valve, air valve and primary combustion pipe, described air valve comprises primary air valve and secondary air valve, the combustion gas that described gas valve is installed on described primary combustion pipe enters on the pipe, the air that described primary air valve is installed on described primary combustion pipe enters on the pipe, the flame-thrower nozzle of described primary combustion pipe is connected with the fuel inlet of described burner hearth, and the air that described secondary air valve is installed on described burner hearth enters on the pipe.
In the use procedure, air enters the primary combustion pipe by the primary air valve, fuel enters the primary combustion pipe by gas valve, fuel and air mix in the primary combustion pipe and the high velocity jet primary combustion produces the short flame of aubergine flame envelope, short flame enters burner hearth, the thrust of being sprayed in burner hearth forms swirl injection along the quirk of furnace chamber and aluminum melting crucible, make heat radiation energy and flue gas spiral promotion in burner hearth, prolonged the time that thermal energy stops in burner hearth, in this process, air enters burner hearth by secondary air valve, finishes second-time burning.
According to the actual range between combustion tube and the burner hearth, in order to reach the most rational linking, be connected by steel pipe between described primary combustion pipe and the described burner hearth.
The beneficial effects of the utility model are:
Because fuel and air form second-time burning in the utility model, make burning more thorough, thereby reduced flue gas velocity and exhaust gas temperature, have reduced the oxygen content in smoke density and the flue gas, energy-saving effect is fairly obvious, and is conducive to environmental protection.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, the utility model comprises burner hearth 6, gas valve 1, air valve, primary combustion pipe 2 and steel pipe 3, air valve comprises primary air valve 4 and secondary air valve 5, the combustion gas that gas valve 1 is installed on primary combustion pipe 2 enters on the pipe, the air that primary air valve 4 is installed on primary combustion pipe 2 enters on the pipe, be connected by steel pipe 3 between the fuel inlet of the flame-thrower nozzle of primary combustion pipe 2 and burner hearth 6, the air that secondary air valve 5 is installed on burner hearth 6 enters on the pipe.
As shown in drawings, in the use procedure, air enters primary combustion pipe 2 by primary air valve 4, fuel enters primary combustion pipe 2 by gas valve 1, fuel and air mix in primary combustion pipe 2 and the high velocity jet primary combustion produces the short flame of aubergine flame envelope, short flame enters burner hearth 6 after by steel pipe 3, the thrust of being sprayed in burner hearth 6 forms swirl injection along the quirk of furnace chamber and aluminum melting crucible, make heat radiation energy and flue gas spiral promotion in burner hearth 6, prolonged the time that thermal energy stops in burner hearth 6, in this process, air enters burner hearth 6 by secondary air valve 5, finishes second-time burning.
