In Figs. 2-4, a fan heater 3 is shown, which fan heater 3 comprises a housing 31, an axial fan 32 and a heat exchanger 33, wherein the housing 31 is provided with an air inlet and a fan blade air outlet 34, the heat exchanger 32 is a coil pipe, one end of the heat exchanger is provided with an inlet, the other end of the heat exchanger is provided with an outlet, the axial fan 32 is arranged on the housing 31, and the heat exchanger 33 is opposite to the axial fan 32. The steam inlet pipe 2 is communicated with the inlet end of the heat exchanger 33 of the warm air blower 3, and the outlet end of the heat exchanger 33 of the warm air blower 3 is communicated with the condensed water recovery pipe 4. The fan heater 3 of the steam treatment device can be arranged on the roof of a factory building for heating the factory building.

The working principle of the steam treatment device in working is as follows: when the pressure in the flash tank is greater than the use pressure required by a workshop, high-temperature and high-pressure steam in the flash tank needs to be discharged from a flash tank discharge pipe 1, at the moment, a first valve 5 is closed, a second valve 6 is opened, steam can enter a steam inlet pipe 2 and then flows into a bent pipe heat exchanger of a warm air blower 3, an axial flow fan of the warm air blower 3 guides air flow to blow to the heat exchanger, the air flow is heated by the heat exchanger to form warm air, the warm air enters the workshop for heating, the steam in the heat exchanger is condensed into water through the air flow, and finally the water flows into a condensate water recovery pipe 4 for recovery.

In a specific embodiment, a plurality of fan heaters 3 can be installed, the fan heaters 3 are connected in parallel between the steam inlet pipe 2 and the condensate recovery pipe 4, a third valve 7 is installed at the inlet end of the heat exchanger of each fan heater 3, and the third valve 7 is preferably a manual butterfly valve. According to the amount of hot steam discharged from the flash tank in practice, different numbers of warm air blowers 3 can be selectively started to work, and a third valve 7 on the warm air blowers 3 is opened when the warm air blowers 3 work.

In this embodiment, the first valve 5 and the second valve 6 are preferably manual butterfly valves. The safety valve 8 is also arranged on the flash tank discharge pipe 1, and the safety valve 8 is used for relieving pressure of the flash tank and ensuring safety of the flash tank.
