[0028] Embodiment 1

[0029] See Figure 1 , the steam inversion system for pile pools in the embodiment of the present application includes:

[0030] Multiple curing pools 100, steam enters the curing pools to heat and cure the pipe piles in the curing pools; the curing pool includes a pool body and a pool cover, the pool cover is openable, and when the pool cover is closed, it forms a closed space with the pool body, and pressure relief holes are distributed on the pool cover to prevent excessive internal steam pressure;

[0031] The main steam supply pipe 200 and the steam supply branch pipes 210 corresponding to each steam curing pond. One end of each steam supply branch pipe 210 is connected to the steam curing pond 100, and the other end is connected to the main steam supply pipe 200. The main steam supply pipe is connected to a steam generating device, and the steam generated by the steam generating device passes through the main steam supply pipe 200 and the steam supply branch pipes 210 in sequence to supply steam to each steam curing pond 100. Conventionally, the steam generating device is a water heating device that generates steam by heating water.

[0032] The main steam return pipe 300 and the steam return branch pipes 310 corresponding to each steam curing pond. One end of each steam return branch pipe 310 is connected to the steam curing pond 100, and the other end is connected to the main steam return pipe 300. After steam curing, the residual steam in the steam curing pond is evacuated.

[0033] A first electric control valve 220 is provided on the steam supply branch pipe 210, and a second electric control valve 320 and a first steam extraction pump 330 are provided on the steam return branch pipe 310.

[0034] The pipe pile pond-to-pond steam inversion system provided by the embodiment of the present application is different from the prior art in that an additional steam inversion assembly is provided. The steam inversion assembly includes: steam inversion branch pipes 400 corresponding to each steam curing pond. One end of each steam inversion branch pipe 400 is connected to the steam curing pond 100, and the other end is connected to the main steam return pipe 300. A third electric control valve 410 and a second steam supply pump 420 are provided on the steam inversion branch pipe 400. The steam supply direction of the second steam supply pump 420 is from the main steam return pipe 300 to the steam curing pond 100.

[0035] The pipe pile steam curing generally can be divided into a preheating stage, a heating stage, a heat preservation stage, and an exhaust steam cooling stage. In the preheating stage, the heating stage, and the heat preservation stage, steam is supplied to the steam curing pond through the steam supply branch pipe. At this time, the first electric control valve is opened, and the second electric control valve and the first steam extraction pump are closed. The opening amplitude of the second electric control valve is controlled based on feedback by a temperature sensor to control the temperature of the steam curing pond. In the exhaust steam cooling stage, the first electric control valve is closed, and the second electric control valve and the first steam extraction pump are opened. It can be understood that the pipe pile steam curing process and the temperature control of each process stage belong to the scope of the prior art.

[0036] The steam inversion assembly provided by the embodiment of the present application operates in the preheating stage, and the process is as follows:

[0037] For the steam curing ponds arranged in an array, when a certain steam curing pond A is in the preheating stage, if there are other steam curing ponds B1, B2... in the exhaust steam cooling stage nearby, at this time, the residual steam in the steam curing ponds B1, B2 is discharged into the main steam return pipe. Then, the third electric control valve and the second steam supply pump of the steam inversion assembly corresponding to the steam curing pond A can be started to send the remaining steam near the main steam return pipe to the steam curing pond A, and the pipe piles in the steam curing pond A1 are preheated using the residual heat of the remaining steam, achieving the effect of recycling the residual heat of the remaining steam.

[0038] Exemplarily, it can be determined that curing pond A enters the preheating stage by the signal of closing the cover of curing pond A. After starting curing pond A and loading the pipe piles into curing pond A, it is first necessary to close the cover. By setting a cover closing signal detection sensor on each curing pond, the cover closing of the curing pond triggers the cover closing signal, and the cover closing signal triggers the operation of the steam inversion component; the cover closing signal detection sensor can use conventional existing sensors such as photoelectric sensors, spring switches, and micro switches to detect the cover closing signal.

[0039] Therefore, based on the pipe pile pond-to-pond steam inversion system provided in the embodiments of the present application, the method for recycling surplus steam and waste heat is as follows: After curing pond A is started, it is determined whether there is a nearby curing pond B that is exhausting steam. If there is a nearby curing pond B in the stage of exhausting steam and cooling down, the third electric control valve and the second steam supply pump of the steam inversion component corresponding to curing pond A are started, and the surplus steam in the steam return main pipe is sent to curing pond A.

[0040] Among them, the judgment criterion for proximity is set as: the physical distance between curing pond A and curing pond B is less than a preset threshold (for example, 10 meters);

[0041] Or, when all curing ponds are arranged in sequential order numbers, for example, the sequence number of curing pond A is 3 and the sequence number of curing pond B is 5, the judgment criterion for proximity can also be set as: the difference in sequence numbers between curing pond A and curing pond B does not exceed a preset threshold (for example, 3).

The steam return main pipe is connected to the high-temperature water tank, and the steam waste heat is used to heat the liquid in the high-temperature water tank to store heat; thus, the steam waste heat is recycled; one end of the hot water branch pipe is connected to the curing pond, the other end of the hot water branch pipe is connected to the hot water main pipe, the hot water main pipe is connected to the high-temperature water tank, a water pump is arranged on the high-temperature water tank, the water outlet of the water pump is connected to the hot water main pipe, a spray pipe connected to the hot water branch pipe is arranged in the curing pond, a fourth electric control valve is arranged on the hot water branch pipe, and in the early stage of curing, the hot water in the high-temperature water tank is pumped by the water pump and sequentially passes through the hot water main pipe, the hot water branch pipe, and the spray pipe to preheat the pipe piles in the curing pond.
