The present invention the integrated combustion type perlite bloating plant based on spiral tube heat exchange basic functional principle with
The course of work：
(1) during perlite high-temperature roasting expanding processing, flow of cooled air is continuously blasted sky by air blower 5
Letter shoot road 4, to form the air draught of one-way flow in airflow pipe 4, the air draught of one-way flow passes through
After airflow pipe 4 is delivered to spiral heat exchange tube road 2, and in the interior air gas for forming one-way flow in spiral heat exchange tube road 2
Stream carries out fast cooling by the cold air of one-way flow in pipeline to the inner wall for expanding the burner hearth masonry walls wall 12 of furnace body 1
Cooling, the local temperature to avoid the burner hearth masonry walls wall 12 of expansion furnace body 1 is excessively high, and utilizes expansion 1 burner hearth 11 of furnace body
Interior high temperature preheats the cold air of one-way flow in pipeline, and the burner hearth 11 of expansion furnace furnace body 1 is discharged to carry out waste heat
It recycles.Spiral heat exchange tube road 2 be arranged in the shape of a spiral expansion furnace body burner hearth 11 in, increase spiral heat exchange tube road 2 with
The area of heat contact in burner hearth 11, extends flowing time of the air draught in spiral heat exchange tube road 2, improves spiral
The efficiency of air heat exchange in heat exchange pipeline 2.The flow of cooled air of one-way flow is empty after the heat exchange of spiral heat exchange tube road 2
Temperature degree is up to 300 DEG C~500 DEG C.In the actual production process, control and regulation air stream is provided on airflow pipe 4
The flow regulator of amount, and adjusting control device is provided on air blower, to be adjusted simultaneously by flow regulator and controller
The flow and flow rate for controlling air in spiral heat exchange tube road 2 obtains lower temperature to realize when air mass flow is big, flow velocity is fast
300 DEG C~400 DEG C of hot-air obtains the hot-air of 400 DEG C~500 DEG C of higher temperature when air mass flow is small, flow velocity is slow,
To be swapped out the hot-air within the scope of required temperature according to actual needs.
(2) hot-air flows into the gas mixing chamber 61 of gas burner 6 after the heat exchange of spiral heat exchange tube road 2, from natural
Gas air inlet 611 enters the natural gas of gas mixing chamber 61 and the high warm for entering gas mixing chamber 61 from air inlet 612
Air is uniformly mixed in moment in the gas mixing chamber 61, and make the natural gas of room temperature carry out Hybrid Heating with formed temperature compared with
The mixed fuel gas of high heat, avoids mixed gas local temperature excessively high；The mixed fuel gas of the higher heat of temperature is from gas
The gas mixing chamber 61 of volumetric combustion device 6 flows into gas catalysis chamber 62, due to the day in the mixed fuel gas of the higher heat of temperature
Right gas has higher temperature (200 DEG C or more) so that natural gas exists with the gas catalysis oxidant 621 in gas catalysis chamber 62
Catalytic oxidation occurs under hot conditions, improves the catalysis oxidation efficiency of natural gas.
Since airstrainer 622 is transverse in gas catalysis chamber 62, so that gas catalysis chamber 62 forms upper chamber
And lower chamber, gas catalysis oxidant 621 are set on airstrainer 622 and fill up upper chamber, gas catalysis chamber 62
The position of upper correspondence chamber to its upper is equipped with the air outlet that be connected to upper chamber, corresponding under it on gas catalysis chamber 62
The position of portion's chamber is equipped with the air inlet port 626 being connected to lower chamber, and the air inlet port 626 and gas of gas catalysis chamber 62 are mixed

Logical, gas catalysis oxidant 621 is arranged on airstrainer 622, and is filled in the upper chamber of gas catalysis chamber 62,
Effective closure is formed with the air outlet to gas catalysis chamber 62, so that the lower chamber formation of gas catalysis chamber 62 has
The pressurizing chamber of the mixed fuel gas of the higher heat of temperature, i.e. the higher heat of the indoor temperature of lower chamber of gas catalysis chamber 62
Certain pressure difference can be formed between mixed fuel gas and the air inlet pipe of gas spray head 63, when the mixing of the higher heat of temperature is fired
Material gas constantly concentrates on the lower chamber of gas catalysis chamber 62, and the mixed fuel gas of the higher heat of temperature will pressurize upwards
Formed turbulent flow flow at high speed air-flow, push the higher heat of temperature mixed fuel gas in combustion gas unite molecule with fire
Gas catalytic oxidant 621 comes into full contact with, and the combustion gas in mixed fuel gas to reach the higher heat of temperature is united molecule point
From the purpose at combustion gas macromolecular mass, and detach lower chamber indoor height of the combustion gas macromolecular mass in gas catalysis chamber 62 of formation
Under the action of pressure gas stream, continue the indoor gas catalysis oxidant 621 of upper chambers for quickly being repelled away from gas catalysis chamber 62, finally
So that the combustion gas macromolecular mass that separation is formed is delivered to the air inlet pipe of gas spray head 63 in the form of combustion gas subset, that is, make
Combustion gas subset after dissociation is rapidly separated the carrier for being adsorbed with active constituent formed in gas catalysis oxidant 621 and forms
For the combustion gas subset of desorption, the combustion gas subset of desorption continues the air inlet along gas spray head 63 under the action of pressure difference
Pipe quickly flowing, the air inlet pipe of gas spray head 63, which is equipped with, is coated with magnetizer, and magnetizer is for the natural gas combustion that induces and polarize
Gas subset formed marshalling combustion gas small molecule chain, and make combustion gas small molecule chain under the impetus of air-flow along
The air inlet pipe olderly flowage of gas spray head 63, in this way, combustion gas small molecule chain is easier to capture when burning at gas spray head 63
Flame reaches quick igniting, clean-burning purpose, to effectively increase the hot combustion rate of Natural Gas, to realize very
Few generate even does not generate NO substantiallyX, the pollutants such as CO and CH, have the effect of efficiently, energy-saving and environmental protection.
