[0013] The utility model has the following beneficial effects:

[0014] 1. By setting up a recovery mechanism, when the condensate of the boiler needs to be recovered, the device can be started. After the condensate flows into the device, due to the effect of buoyancy, it will push up the floating ball in the transfer box, thereby driving the pressure relief block and the pressure block to move upward, so that the pressure relief pipe is closed and the pressure pipe is opened. The air pressure pushes the water into other devices through the connecting pipe. When the water level drops, the floating ball will also move downward, thereby driving the pressure relief pipe to open and the pressure pipe to close for circulation. This helps to improve the energy efficiency of the steam system, reduce energy consumption and waste, and maintain the pressure balance in the steam system to avoid instability caused by condensate accumulation or vacuum generation, which helps to maintain the normal operation of the system and extend the service life of the equipment;

[0015] 2. By setting the piston, when the condensed water in the device flows to the piston through the connecting pipe, the water pressure will push the piston backward, opening a gap for the condensed water to flow. Due to the action of the spring telescopic rod, the piston will form a smooth-open and reverse-closed environment for the connecting pipe, ensuring that the condensed water flows in the system in the correct direction, avoiding unnecessary mixing or backflow, and helping to improve the stability, reliability and safety of the system.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figure 1-7 As shown, the present utility model is a condensate water recovery and utilization device for a natural gas boiler, including a rectangular bottom plate 1, and a recovery mechanism and a condensation mechanism are arranged on the rectangular bottom plate 1;

[0029] The recovery mechanism includes a floating component, a connecting component, an elastic component and a pressure control component.

[0035] By setting the pressure control component, it can ensure that the device operates within a safe range, avoiding equipment damage caused by excessive pressure or the device being unable to work properly due to too low pressure.

[0036] As shown in the figure, the condensation mechanism includes a condensation water tank 22 arranged above the rectangular bottom plate 1, a support frame 23 is fixedly sleeved on the outer wall of the condensation water tank 22, and the bottom end of the support frame 23 is fixedly connected to the rectangular bottom plate 1, two baffles 24 are fixedly installed on the inner wall of the condensation water tank 22, and a plurality of half baffles 241 are fixedly installed on the inner wall of the condensation water tank 22, and a plurality of coolant circulation pipes 25 are arranged in the condensation water tank 22, and the plurality of coolant circulation pipes 25 pass through the two baffles 24, and the plurality of coolant circulation pipes 25 pass through the plurality of half baffles 241, and a baffle 2 26 is fixedly installed on the top of the corresponding baffle 1 24, and the baffle 2 26 is adapted to the condensation water tank 22, a coolant inlet 27 is fixedly installed on the outer wall of the condensation water tank 22, a coolant outlet 28 is fixedly installed on the outer wall of the condensation water tank 22, and an air intake pipe 29 is fixedly installed on the outer wall of the condensation water tank 22.

[0037] By providing a condensing mechanism, when the steam in the boiler enters the condensing water tank 22, it will be condensed into water, which can be recycled and reused after treatment, thereby achieving the purpose of saving water resources.

[0038] As shown in the figure, two connecting pipes 30 are fixedly installed on the outer wall of the transfer water tank 2, and the ends of the corresponding connecting pipes 30 extend into the condensation water tank 22.

[0040] A specific application of this embodiment is as follows: During use, first introduce the steam of the boiler into the condensate tank 22 through the intake pipe 29, and then pour the coolant into the condensate tank 22 through the coolant inlet 27. After the coolant circulates through the coolant circulation pipe 25, it flows out through the coolant outlet 28 to take away the heat of the steam. After the steam turns into liquid, due to the effect of pressure, the water passes through the piston 34 in the connecting pipe 30 and achieves the effect of being unobstructed when flowing forward and closed when flowing backward under the action of the telescopic rod 32 and the second spring 33. After the water flows into the transfer tank 2, the floating ball 4 will drive the U-shaped frame 6 on the first connecting rod 5 due to the buoyancy of the water, causing the second connecting rod 10 to move upward under the action of the sliding rod 7 and the U-shaped frame 6. When the water in the transfer tank 2 reaches a certain amount, the first spring 14 will move the second support rod 16 on the second connecting block 15 upward under the action of the third connecting block rod 12 and the second connecting rod 10. At this time, the pressure in the transfer tank 2 will flow out through the pressure relief pipe 21 to stabilize the pressure in the transfer tank 2. The second support rod 16 drives the pressure relief pipe block 20 and the pressure adding pipe block 18 upward to close the pressure relief pipe 21 and open the pressure adding pipe 19. At this time, the air pressure enters the transfer tank 2 through the pressure adding pipe 19, and the condensed water can flow out through the corresponding connecting pipe 30.
