Referring to fig. 3, in one embodiment, the steam delivery mechanism 200 further includes a dust remover 244, and the dust remover 244 is disposed at the end of the tail gas pipe 240. Since a large amount of dust is inevitably generated during the combustion of coal in the steam furnace 210, in order to treat the large amount of dust in the exhaust gas, the dust remover 244 is a wet dust remover in this embodiment, which separates and collects dust particles in the exhaust gas by utilizing the hydrophilic wetting of water. In other embodiments, the dust collector is a dry dust collector that uses the inertial and gravitational effects of the dust to effect settling of the dust. When the steam boiler 210 burns clean energy such as natural gas, less dust particles are generated, in another embodiment, the dust remover is an electric dust remover, the electric dust remover guides dust-containing air flow into an electrostatic field, gas is ionized under the action of a high-voltage electric field to generate positive and negative ions, the dust particles can bear charges when meeting the charged ions, and the dust particles are removed to a settling plate with the sign opposite to the negative charges of the dust particles at a certain speed to complete settling. Therefore, dust in the exhaust gas of the steam furnace 210 is removed, and the environmental protection performance of the steam conveying mechanism 200 is improved.

In order to desulfurize the offgas discharged from the steam furnace 210. In one embodiment, the steam delivery mechanism 200 further comprises a desulfurizer disposed at the end of the tail gas pipe 240. The fuel of the steam furnace 210 inevitably contains sulfur and sulfur-containing compounds, and the exhaust gas generated by combustion also contains harmful gases such as sulfur dioxide. Further, the desulfurizer is a box-type desulfurizer. In further embodiments, the desulfurizer is a tower desulfurizer. Therefore, harmful gases such as sulfur dioxide in the exhaust gas of the steam furnace 210 are removed, and the environmental protection performance of the steam conveying mechanism 200 is improved.

To improve the combustion efficiency of fuel in the steam boiler 210 and reduce the combustion cost. Referring to FIG. 3, in one embodiment, the steam delivery mechanism 200 further includes an air preheater 245 and a return pipe 246, the air preheater 245 is at least partially disposed in the exhaust pipe 240, the air preheater 245 is connected to an input end of the return pipe 246, and an output end of the return pipe 246 is communicated with the combustion chamber 211. On one hand, the air preheater 245 accelerates the drying, firing and burning processes of the fuel in the combustion chamber 211 by using the waste heat of the tail gas discharged from the steam boiler 210, thereby ensuring the stable combustion of the fuel in the steam boiler 210 and improving the combustion efficiency of the fuel. On the other hand, the air preheater 245 heats the combustion-supporting air by using the waste heat of the exhaust gas discharged from the steam boiler 210, and the hot air improves the incomplete combustion condition of the fuel, so that the fuel in the steam boiler 210 is fully combusted, and the conversion rate of the fuel is improved. In this way, the air preheater 245 increases the combustion efficiency of the steam boiler 210 by using the waste heat of the exhaust gas discharged from the steam boiler 210, thereby reducing the combustion cost of the steam boiler 210.

In order to further improve the combustion efficiency of the fuel in the steam oven 210, in one embodiment, the steam oven 210 is further provided with a blower (not shown). In this embodiment, the input of the blower is connected to the output of the return conduit 246. The heated air in return conduit 246 heats the air used for combustion to assist the fuel under the suction of the blower. In this embodiment, the blower is a variable frequency blower, and the blower flow rate is controlled by changing the rotation speed of the ac motor with a frequency converter, thereby greatly reducing the energy loss caused by the flow rate regulation and control in the past mechanical manner. Thus, the fuel in the steam boiler 210 is sufficiently combusted, and the conversion rate of the fuel is improved. The production cost of the steam delivery mechanism 200 is reduced.

In order to reduce the heat dissipation of the steam delivery mechanism 200 and the production cost of the steam dissipation device, in one embodiment, the water pipe 242 and the recovery pipe 170 are provided with heat insulation sleeves, and the heat insulation sleeves are made of rubber and plastic heat insulation materials. It should be noted that the water in the water tank 241 is heated by the tail gas pipe 240 to increase the temperature, and the heat insulation sleeve arranged outside the water pipe 242 reduces the heat loss in the process of the warm water from the water tank 241 to the steam boiler 210. Further, a heat insulation sleeve is arranged outside the return pipe 246, and the heat insulation sleeve is made of high-temperature resistant materials. Therefore, heat loss of the warm water and the high-temperature air in the steam conveying mechanism 200 is reduced, and the production cost of the steam dispersing device is reduced.
