The small end opening of bucket shape opening is connect with natural gas air inlet, and big end opening and the gas mixing chamber of the first funnel-shaped opening connect
Logical, the small end opening of the second funnel-shaped opening is connect with air inlet, and big end opening and the gas of the second funnel-shaped opening mix
Close chamber connection.The first funnel-shaped opening and the second funnel is respectively adopted in the natural gas air inlet and air inlet of gas mixing chamber
Shape opening design so that natural gas and air are sprayed respectively by the first funnel-shaped opening and the second funnel-shaped opening, due to the
The opening diameter of one funnel-shaped opening and the second funnel-shaped opening increases gradually, can form demolition effect in gas mixing intracavitary,
On the one hand the gas flow rate of natural gas and air point is reduced, reduces the pressure of follow-up air-flow inflow gas mixing chamber so that day
The space increase of right gas and air dispersing contact, realizes that natural gas and air reach the mixing that is uniformly dispersed in moment；On the other hand,
As gas flow radius increases, and will along the gas flow rate of the first funnel-shaped opening and/or the second funnel-shaped opening side wall
Higher than the first funnel-shaped opening and/or the gas flow rate of the second funnel-shaped opening center, in this way so that the natural gas of room temperature
It will be more towards the outer wall dispersion flows of gas mixing chamber with air so that the contact area bigger of natural gas and air,
The mixing velocity of gas mixing chamber is accelerated, and is not easy to form the phenomenon that natural gas gas local concentration is excessively high, is conducive to improve natural
The combustion rate of gas.

The basic functional principle and the course of work of the energy-efficient combustion type perlite bloating plant of the present invention：
(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 the air draught of one-way flow is formed in the spiral heat exchange tube road 2,
It is cold that fast cooling is carried out to the inner wall for expanding the burner hearth masonry walls wall 12 of furnace body 1 by the cold air of one-way flow in pipeline
But, the local temperature to avoid the burner hearth masonry walls wall 12 of expansion furnace body 1 is excessively high, and utilizes and expand in 1 burner hearth 11 of furnace body
High temperature the cold air of one-way flow in pipeline is preheated, and discharge the burner hearth 11 of expansion furnace furnace body 1 to carry out waste heat again
It utilizes.Spiral heat exchange tube road 2 is arranged in the shape of a spiral in the burner hearth 11 of expansion furnace body, increases spiral heat exchange tube road 2 and stove
The area of heat contact in thorax 11, extends flowing time of the air draught in spiral heat exchange tube road 2, improves spiral and change
The efficiency of air heat exchange in hot channel 2.The flow of cooled air of one-way flow is after the heat exchange of spiral heat exchange tube road 2, air
Temperature is up to 300 DEG C~500 DEG C.In the actual production process, control and regulation air mass flow is provided on airflow pipe 4
Flow regulator and adjusting control device is provided on air blower, to adjust and control by flow regulator and controller
The flow and flow rate of air in spiral heat exchange tube road 2 processed to realize when air mass flow is big, flow velocity is fast, obtains lower temperature 300
DEG C~400 DEG C of hot-air, when air mass flow is small, flow velocity is slow, the hot-air of 400 DEG C~500 DEG C of higher temperature is obtained, with root
The hot-air being swapped out according to actual needs in the range of required temperature.
(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
The natural gas that gas air inlet 611 enters gas mixing chamber 61 is warmed with entering the high of gas mixing chamber 61 from air inlet 612
