[0002] Steam recovery machine, also known as steam condensate recovery device, steam condensate recovery device, condensate recovery device, closed condensate recovery device, etc., is the main equipment for recovering condensate in steam heating system, and there are two types of recovery: separate recovery and closed recovery. In the closed recovery system, all condensate pipelines are under constant positive pressure, and the system is closed. Most of the energy of condensate in the system is directly recovered to the boiler through the recovery equipment, and the recovery temperature of condensate is only lost in the cooling part of the pipe network. The existing recovery machine cannot effectively control the temperature of steam recovery, which easily causes waste of heat energy. Summary of the invention

[0006] Preferably, the number of the blades and the number of the hooks are both four, and the controller model is HZ300.

[0007] Preferably, an air inlet is opened on the surface of the connecting disk corresponding to the heating tube. The air inlet disk adjusts the rotation of the fan blades through a controller to control the amount of air intake of the heating tube. The fan blades are pulled by springs and hooks to rotate back into the air inlet disk for reset movement.

[0008] Preferably, a heat-insulating filler is installed between the protective shell and the heating tube.

[0009] Preferably, the air inlet pipe, protective shell, water tank, downpipe, air inlet plate and heating tube are all made of stainless steel.

[0010] Compared with the prior art, the present invention has the following advantages: the present invention has an ingenious structure, a rigorous design and a low use cost; when a steam recovery economizer is used in a boiler to recover steam, the air outlet of the boiler is connected through an air inlet pipe, and steam flows into the air inlet disk through the air inlet pipe. The air inlet disk adjusts the rotation of the fan blades through a controller to control the air intake amount of the heating tube and the temperature inside the heating tube.

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] As shown in the figure, a high-efficiency temperature-controlled steam recovery economizer includes an air intake pipe 1, a protective shell 2, a water tank 3, a downpipe 4, an air intake disc 5 and a heating tube 7. A connecting disc 6 for fixing the heating tube 7 is welded on the left side of the protective shell 2. A heating tube 7 for recovering steam is installed inside the protective shell 2 through the connecting disc 6. An air intake disc 5 for controlling the steam intake amount is integrally formed on the outer side of the connecting disc 6. The air intake disc 5 is composed of a fixing ring 9, a fan blade 8 and a hook 10. The hook 10 is welded to the inner wall of the fixing ring 9. One end of a spring 11 is welded inside the fan blade 8, and the other end of the spring 11 is connected to the hook 10. A connecting groove 12 is provided inside the fan blade 8 corresponding to the hook 10. The fan blade 8 is connected to the controller through the air intake disc 5 to control the rotation.
