The invention provides a high pressure heater 10 drainage liquid level control auxiliary device, comprising: the high-pressure heater 10, there is water pipe 110 on the outer wall of the high-pressure heater 10, the inboard wall of the high-pressure heater 10 has mounting parts 120, the mounting part 120 includes the first mounting part 121 and the second mounting part 122, the first mounting part 121 links with water pipe 110; the floating plate 20 is arranged in the high-pressure heater 10, a first fitting piece 210 and a second fitting piece 220 are respectively arranged on two sides of the floating plate 20, the first fitting piece 210 is matched with the first mounting part 121, and the second fitting piece 220 is connected with the second mounting part 122 in a sliding manner; a cavity is arranged in the floating plate 20 and is communicated with the water pipe 110, more than one water through hole 230 is arranged at the top of the floating plate 20, and the water through holes 230 are communicated with the cavity; the floating plate 20 is installed at a predetermined height inside the high pressure heater 10 according to a predetermined water level of the water level, because the height of the floating plate 20 corresponds to the water level, if the water level is higher than the floating plate 20, the boiling water and water vapor enter the cavity inside the floating plate 20 through the water passage holes 230, and thus the water entering the cavity is discharged out of the high temperature heater through the water passage pipe 110 for recycling; when the water level is lower than the floating plate 20, the water level control module 40 discharges less water from the high pressure heater 10 to the outside, and finally the water level rises, so that the water level in the high pressure heater 10 can be stabilized.
Specifically, the first mounting part 121 is a mounting ring, the first mating member 210 is a circular ring, and the size of the circular ring is matched with that of the mounting ring; so that the first mounting part 121 and the first fitting member 210 are more stably mounted.
Specifically, the second mounting portion 122 is a groove, the second mating member 220 is a mating ring, and the mating ring is slidably connected with the groove; because the water level inside the high pressure heater 10 can float up and down, the second fitting piece 220 can slide in the groove, so the second fitting piece 220 can float up and down along with the shaking of the water level, and if the water level is just higher than a preset position, redundant water can enter the floating plate 20, so that the water level inside the high pressure heater 10 can be stabilized to be more stable.
Specifically, the direction of the long side of the groove is consistent with the axial direction of the high-pressure heater 10; since the direction of the long side of the groove is kept coincident with the axial direction of the high pressure heater 10, it is ensured that the sliding of the second fitting member 220 is kept in the vertical direction.
Specifically, the water through holes 230 are arranged at the top of the floating plate 20, and the water through holes 230 are uniformly arranged at intervals along the circumferential direction of the floating plate 20; the floating plate 20 is provided with an arc groove 240, the section of the arc groove 240 is arc-shaped, and the arc groove 240 is communicated with the top and the bottom of the floating plate 20; the top of the arc groove 240 is connected with the limber hole 230; the water higher than the top of the floating plate 20 directly enters the water passage holes 230 formed at the top of the floating plate 20, and is discharged to the outside of the high pressure heater 10 through the water passage pipe 110 communicating with the first mounting part 121 to be recycled.
Specifically, the high-pressure heater also comprises a liquid level meter 30, wherein a mounting groove 310 is formed in the side wall of the high-pressure heater 10, and the liquid level meter 30 is matched with the mounting groove 310; the liquid level gauge 30 is used to observe the water level inside the high pressure heater 10.
Specifically, the device further comprises a liquid level control module 40, wherein the liquid level control module 40 is arranged on one side of the high-pressure heater 10; the liquid level control module 40 is connected with the side wall and the bottom of the high-pressure heater 10; the working process of the liquid level control module 40 is as follows: when the water level in the high-pressure heater 10 rises, the steam volume signal is reduced and is transmitted to the steam-liquid two-phase flow steam trap 410 through the gas phase pipe 411, the liquid level in the steam-liquid two-phase flow steam trap 410 rises, the drainage displacement is increased, and finally the water level in the high-pressure heater 10 is lowered; on the contrary, when the water level in the high pressure heater 10 drops, the steam flow signal increases and is transmitted to the steam-liquid two-phase flow steam trap 410 through the gas phase pipe 411, the liquid level in the steam-liquid two-phase flow steam trap 410 decreases, the drainage discharge amount decreases, and finally the water level in the high pressure heater 10 rises, thereby achieving the purpose of controlling the water level.
The drainage liquid level control auxiliary device of the high-pressure heater 10 provided by the invention can enable the water level in the high-pressure heater 10 to be more stable and the measurement of the water level to be more accurate; after all, the adjustment of the liquid level control module 40 is a small-range water level condition, when the water level is too much and the liquid level control module 40 cannot be adjusted, because the high-pressure heater 10 drains the auxiliary device for liquid level control, the water vapor in the high-pressure heater 10 can be quickly discharged, the discharged water vapor can be recycled, and no energy is wasted;
the specific working principle is as follows: the floating plate 20 is installed at a predetermined height inside the high pressure heater 10 according to a predetermined water level, because the height of the floating plate 20 corresponds to the water level, if the water level is higher than the floating plate 20, the boiling water and water vapor enter the cavity inside the floating plate 20 through the water passage holes 230, and thus the water entering the cavity is discharged out of the high pressure heater 10 through the water passage pipe 110 for recycling; when the water level is lower than the floating plate 20, the water level control module 40 discharges less water from the high pressure heater 10 to the outside, and finally the water level rises, so that the water level in the high pressure heater 10 can be stabilized.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
