Specific embodiment
It is described in detail referring to the drawings with reference to embodiment, to be carried out more to technical characteristic of the invention and advantage
Deep annotation.
As shown in Figure 1-2, a kind of many source of the gas gas air supply systems of the invention, including gas pipeline 10 and PLC are controlled
System processed, is sequentially provided with ball valve 3, filter 4, turbine flowmeter 8, electric control valve 9, calorific value on described gas pipeline 10
Instrument 11, oxygen conten analyser 13 and static mixer 14, are provided with pressure transmitter 5, flow transmitter 6 on turbine flowmeter 8
With temperature transmitter 7, caloric value instrument 11 and oxygen conten analyser 13 are arranged between electric control valve 9 and static mixer 14
On gas pipeline 10, static mixer 14 connects the gas pipeline of upstream source of the gas A1, upstream source of the gas B2 and downstream client 12 respectively
10, pressure transmitter 5, caloric value instrument 11 and oxygen are also equipped with the gas pipeline 10 between static mixer 14 and downstream client 12
Content analyzer 13；Described PLC control system connects turbine flowmeter 8, electric control valve 9, caloric value instrument 11 and oxygen and contains respectively
Amount analyzer 13, is also connected with pressure transmitter 5, flow transmitter 6 and temperature transmitter 7.
As shown in Fig. 2 PLC control system of the invention receives the pressure transmitter 5, flow installed on turbine flowmeter 8
The data that transmitter 6 and temperature transmitter 7 are gathered, also receive the data that caloric value instrument 11 and oxygen conten analyser 13 are detected,
PLC control system is analyzed calculating by the data for receiving, and controls the work of electric control valve 9, i.e. control enters static
The ratio of the various sources of the gas of the blending of blender 14, so as to reach the calorific value requirement of natural gas needed for downstream client 12.
Operation principle of the invention is as follows：Two kinds of gases to be blended, one is primary source of the gas, and one is servo-actuated source of the gas,
Servo-actuated source of the gas follows the changes in flow rate of active source of the gas and changes automatically, is blended according to the ratio being previously set.
As shown in Figure 1-2, it is described using two kinds of sources of the gas in the present embodiment, practical work process can increase as needed
