る層流化つまり整流化が計られる。For example, in heating and cooling equipment or hot water equipment,
When supplying fluid to each unit, the fluid contains bubbles, or bubbles are generated when water is heated in boilers, etc., so during a considerable period of time, air conditioning equipment and its units The metal parts of the body or unit as well as the inner walls of the fluid circuit become oxidized and eventually corrode. Therefore, in the fluid circuit of the heating and cooling equipment that passes from a boiler or other supply source to each unit, it is desirable to provide a degassing device on the upstream side of the unit for discharging air bubbles contained in the fluid. Another advantageous benefit of installing a deaeration device in a fluid circuit is that when fluid is pumped using the circulation pump blades in a fluid circuit of air-conditioning equipment, the fluid may bite the inner wall surface of the piping circuit. Because it flows in a turbulent state, it wears down the inner wall surface of the circuit and causes corrosion, but if this turbulent flow goes up the inner diameter of the connecting main pipe and passes through the expansion pipe of the degassing device, which has a larger diameter, it causes damage to automobiles. The exhaust muffler principle, that is, the principle of continuity, reduces the flow rate and pressure, so the flow in the downstream main pipe circuit that connects to the discharge pipe of the deaerator is in a parallel line along the inner wall surface of the fluid circuit. Laminar flow, or rectification, is achieved.

てないことが主な原因である。In this way, by rectifying the flow of the fluid circuit on the downstream side where the deaerator is installed, various elements dissolved in the form of ionic elements in the flowing water are transferred to the inner wall of the circuit due to the ion exchange phenomenon. An iron oxide film is formed, a calcium film is formed on the epithelial surface, a silicic acid film is formed on the epithelial surface, and then a zinc film is formed on the most epithelial surface. The formation of a natural anti-rust film has already been proven by scale analysis at the Hokkaido Industrial Research Institute, and is also well known in the major equipment industry. However, when this type of deaerator is installed in the fluid circuit of air conditioning equipment, depending on the water quality, it may take a considerable amount of time to form the rust-preventing natural film layer on the inner wall surface of the fluid circuit. be. The main reason for this is that, for example, in raw water in Japan, only a very small amount of calcium component, which is the base material of the calcium coating that forms the base layer of the rust-preventive natural coating layer, is dissolved.

Using flange joints at appropriate places on the test bead short tube T. It is desirable to arrange P. Next, regarding a degassing device related to this invention, for example, an inverted Y-shaped degassing device 10 according to an applied design disclosed in the specification of patent application number 1983-026745 shown in FIG. 2 will be summarized. Explain. 31, 3 in Figure 2
3 is an expansion cylinder arranged in an inverted Y shape, and the expansion cylinder 31,
33 are provided with coupling devices 17 and 19 for connection to the upstream inlet conduit C1 and the downstream outlet conduit C2, respectively. The expansion tube 31 arranged in the inverted Y shape
, 33, a gas reservoir cylinder 32 is fixed upwardly. A deaeration pipe 24 is inserted into the gas storage cylinder 32 from the upper wall surface of the gas storage cylinder 32 and attached thereto, and an automatic exhaust valve 25 is fixed to the upper end of the deaeration pipe 24. When the fluid flows from the inflow conduit C1 with a small diameter into the first expansion part E1 of the expansion cylinder 31 with a larger diameter, the fluid flows at a reduced flow rate and pressure according to the "principle of an automobile exhaust muffler". Therefore, the minute air bubbles that were caught in the water flow in the circulation circuit and were flowing with the liquid,
The gas increases its buoyancy in the expansion section E1 and then the second expansion section E2, rises rapidly into the gas reservoir cylinder 32, and is discharged into the atmosphere from the automatic exhaust valve 25 via the degassing pipe 24. . On the other hand, the liquid pumped by the blades of the circulation pump flows in a turbulent manner that bites the inner wall surface of the circuit, as shown by the streamlines in FIG. 3
2, passes through the first expansion section E1, second expansion section E2, and third expansion section E3, and flows into the downstream outlet conduit C2, as shown by the streamlines in FIG. Along the inner wall surface of the circuit, the flow changes from a parallel linear flow to a laminar flow, that is, a rectified flow. In this way, if the flowing liquid in the circuit is provided with conditions such that air bubbles in the water are simultaneously degassed through the deaerator 10 and rectified at the same time, the flowing liquid in the circuit will be dissolved in ionic form as described above. Due to the ion exchange phenomenon of various elements, a strong rust-preventing natural film layer is formed on the inner wall surface of the circuit, consisting of the following layers: iron oxide film, calcium film, silicate film, and zinc film. Therefore, by arranging the deaerator 10 at an appropriate location in the heating and cooling equipment, the air bubbles mixed in the flowing liquid can be degassed all at once to prevent the formation of ferric hydroxide, which is the cause of rust and red water. At the same time, the turbulent flow is rectified and the above-mentioned solid natural film is formed, which has the advantage of preventing corrosion on the inner wall surface of the metal circuit. However, if only a small amount of calcium components are dissolved in the water, Since it takes time and time to form the calcium film that is the base layer for forming the rust-preventing natural film layer, there is a disadvantage that it takes a considerable amount of time to complete the formation of the rust-preventing natural film layer on the inner wall surface of the circuit. It may be harmful.

Coupling devices 52 and 54 are provided at both ends of the connecting pipe section 47 for connection to the upstream conduit P1 and the downstream conduit P2. In the embodiment of the calcium supplement replenishing device of the present invention, since it is configured as described above, the raw water flowing into the connecting pipe section 47 from the conduit P1 easily flows through the introduction action of the fluid deflecting section 49. It is guided into the conduit 48 and rises into the mixing water chamber 60 . The raw water that has flowed into the mixing water chamber 60 passes through the perforated water plate 61 under the influence of the rising water flow generated from the rotating blade 63 that rotates under the action of the water flow.

果がある。The raw water sent into the calcium agent storage chamber 51 passes through the calcium agent layer evenly, taking on a flowing form as if washing the surface of each particle of the calcium agent 53. By allowing the raw water to flow through the calcium agent layer in a flowing manner as if washing it, it has the effect of increasing the release efficiency when the calcium component is eluted from the surface of the granular calcium agent into the water in the form of elemental calcium ions.

えで、引続き脱気装置を設置することが望ましい。Incidentally, as a calcium agent, it is preferable to use one obtained by baking and pulverizing the husks to form activated calcium carbonate, as it has good solubility. The flowing water that has passed through the calcium agent layer becomes calcium ion water, passes through the perforated water plate 61 again, flows out into the mixing water chamber 60, and flows out into the communication pipe section 47 through the outflow conduit 50 as shown by the streamline. Then, it flows into the downstream conduit P2 connected by the coupling device 54, passes through the unit UT shown in FIG. 1, for example, returns to the hot water boiler B through the conduit C, and repeats the circulation of the fluid circuit again. . Therefore, each time flowing hot water passes through the calcium agent replenishing device 40 of the present invention, dissolved calcium ion components become concentrated in the flowing hot water, and calcium ion elements in the flowing hot water are absorbed into the fluid circuit due to the ion exchange phenomenon. A calcium film is quickly formed by adhering to the wall surface, and the object of the invention is achieved. Furthermore, even when the calcium agent replenishment device of the present invention is installed on the upstream side of a water supply piping system, for example, an outflow pipe from an elevated water tank, the same result of film formation as described above can be obtained on the inner wall surface of the downstream piping circuit. At the same time, the calcium ions in the water have the benefit of making the drinking water more delicious and mellow. Incidentally, even after the formation of the rust-preventing natural film layer on all the inner wall surfaces of the fluid circuit is completed, it is desirable to continue installing a deaeration device in order to prevent wear and tear on the inner wall surface due to turbulent flow.
