As background technology is introduced, exist in the prior art thermoelectricity unit air-introduced machine power consumption is more and thermoelectricity unit
The problem of waste heat can not be utilized effectively, in order to solve technical problem as above, present applicant proposes one kind to utilize back pressure machine steam discharge
The system for driving air-introduced machine, makes full use of to the steam discharge of back pressure machine, takes developing heat user, plant area's interior energy is replaced with waste heat
Electricity, waste heat is just utilized as far as possible；Scheme of the present utility model solves the problem of back pressure machine energy cascade utilization, saves
Station service, net coal consumption rate is reduced, improve the utilization rate of company's energy thermal efficiency.
In a kind of typical embodiment of the application, as shown in Figure 1, there is provided one kind is drawn using the driving of back pressure machine steam discharge
The system of blower fan, including air-introduced machine 3, air-introduced machine 3 are connected with steam turbine 2, the air intake of steam turbine 2 and the steam drain of back pressure machine 1
Connection, the steam drain of steam turbine 2 are connected by exhaust line with steam manifold 5.The steam discharge of back pressure machine is made full use of, utilized
The steam discharge of back pressure machine carries out Steam Turbine Driven air-introduced machine, instead of motor drive mode, has saved the energy, reduces station service
