The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1-2, the present invention provides a tail gas combustion apparatus, comprising:
the combustion chamber 1 is cylindrical, and the top of the combustion chamber is provided with an air outlet 2;
the air inlet pipe 6 is annularly arranged on the outer side of the lower part of the combustion chamber 1, one side of the air inlet pipe, which is close to the combustion chamber 1, is uniformly provided with a plurality of air inlet holes 13 communicated with the combustion chamber 1, and the air inlet pipe 6 is connected with a tail gas inlet 9 and an air inlet 8; tail gas and air enter annular intake pipe 6 in, enter into combustion chamber 1 by a plurality of inlet ports 13 after mixing, inlet port 13 along circumferencial direction evenly distributed on the lateral wall of combustion chamber 1, it is more even to admit air, the burning is more abundant.
The igniter 5 is arranged in the combustion chamber 1 and used for oil injection and ignition;
and the heating device 4 is arranged in the combustion chamber 1, so that high temperature is kept in the combustion chamber 1 to ensure that the tail gas is fully combusted.
The air outlet end of the air duct 7 is connected with the air inlet pipe 6 along the tangential direction of the air inlet pipe 6, because the air inlet pipe 6 is provided with an air inlet hole 13 communicated with the combustion chamber 1, if the air duct 7 is connected with the air inlet pipe 6 in a vertical manner, one part of air can directly enter the combustion chamber 1 through the air inlet hole 13, and the other part of air is still in the air inlet pipe 6, so that uneven air inlet is caused; air duct 7 is connected along the tangent line with intake pipe 6, and the inner wall that 1 one side of combustion chamber was kept away from along intake pipe 6 after gaseous entering is that the circumference form is full of intake pipe 6 then gets into combustion chamber 1 through inlet port 13, and more even and gaseous that tail gas and air can mix can enter into combustion chamber 1 simultaneously.
And an air flow meter 12 is arranged at the tail gas inlet 9 and used for detecting the amount of the entering tail gas.
8 departments of air intake are equipped with fan 11, and the tail gas volume that detects according to air flow meter 12 blows in the intake pipe 6 with the air in, guarantees that tail gas can fully burn.
The igniter 5 is an atomizing igniter, and the sprayed kerosene is atomized and ignited, so that the environment is polluted without atomizing and self-burning. The igniter 5 is arranged above the air inlet pipe 6 and close to the air inlet pipe 6, and ignites the gas at the first time.
The heating means 4 are a plurality of ceramic tubes arranged above the inlet tube 6. The igniter 5 is required to be ignited before the equipment is started, the temperature of the ceramic tube is heated to about 820 ℃, so that gas passing through the combustion chamber 1 can be fully combusted, and gases such as carbon monoxide, methane, hydrogen and the like in tail gas can be automatically combusted at high temperature, so that the tail gas treatment chamber can continuously heat the tail gas treatment chamber, and substances passing through the combustion chamber 1 become colorless and odorless.
The ceramic tube is internally provided with a heating rod which is an electric heating rod and used for keeping the temperature of the ceramic tube.
The inside top that is located intake pipe 6 of combustion chamber 1 is equipped with the pressure fire dish 3, and pressure fire dish 3 sets up with combustion chamber 1 is concentric, namely sets up in the center of combustion chamber 1, and its diameter is greater than the radius of combustion chamber 1, is equipped with the interval between the outside edge of pressure fire dish 3 and the combustion chamber 1 inner wall. The hot gas after burning rises and contacts the pressure fire plate 3 to make the rising gas flow to both sides, thereby delaying the rising speed of the gas, prolonging the burning time of the gas in the combustion chamber 1 and ensuring the gas to be more fully burnt.
A temperature sensor 10 is arranged in the combustion chamber 1 and used for detecting the temperature in the combustion chamber 1 and ensuring that the combustion chamber 1 keeps high temperature.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
