Technical Field

Background

Air and impurities are important factors influencing the operation effect and the service life of the heat supply and refrigeration water circulation system, and have great influence on the output of a heat exchanger, the conveying capacity of a pipe network and the heat dissipation capacity of indoor facilities. Meanwhile, air in circulating water causes serious corrosion of the system and cavitation corrosion of parts, impurities accelerate abrasion and accumulation of the system parts, and the service life of the system is shortened. The operation and maintenance mode of the water system can cause the problems to occur repeatedly, heavy exhaust and slag removal labor can be brought to operating personnel before the beginning of a heating or refrigerating season, and unavoidable maintenance cost and user complaints are caused.

The air content in the circulating water is increased by a number of factors such as free gas trapped at the top of the system during initial charging, fine bubbles entrained by the charging or replenishing water and air dissolved in the water, air penetrating through parts of the system that are not well sealed, etc. During operation, fine bubble type and dissolved type gases are released due to changes of pressure and temperature, and are carried by water in a bubble mode for circulation until the fine bubble type and dissolved type gases are gathered at a dead angle position to form a circulating air resistance or a heat transfer air cushion. Impurities and corrosion particles can damage water pumps, valves and cold and heat source equipment in the heating/cooling system. When the sediment in the system increases, the heat exchange begins to deteriorate, so that the output of the equipment is greatly reduced, the valve is blocked and is difficult to open and close, the balance valve loses the regulation characteristic, and the flow area of the pipeline is remarkably reduced and even completely blocked … …. We have found that fouling is far less harmful than the accumulation of fine silt particles and rust when cleaning plate heat exchangers, which cannot be solved by conventional filter scrubbers.

In addition, air and impurities in the pipeline can cause the pipeline to generate noise and reduce the heat transfer effect, longer starting/running time and higher return water temperature are needed, the heat dissipation effect of the system is poor, the system resistance is increased, and the heat supply efficiency is reduced.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The invention is described in further detail below with reference to the accompanying drawings:

as shown in fig. 1 and 2, a spiral-fin type air and impurity separator according to the present invention comprises: the device comprises a cylinder body 1, a spiral wing type separation device 2, an exhaust valve 3 and a blow-down valve 4; the side surface of the cylinder body 1 is respectively provided with a water inlet 11 and a water outlet 12, the spiral fin type separation device 2 is arranged in the cylinder body 1, the exhaust valve 3 is arranged at the upper end of the cylinder body 1, and the drain valve 4 is arranged at the lower end of the cylinder body 1; the spiral fin type separation device 2 is a propeller-shaped structure formed by obliquely arranging tooth-shaped fins, and retention areas are formed among the tooth-shaped fins.

In the embodiment, the spiral fin type air and impurity separator is mainly applied to systems such as heating, refrigeration, solar energy and the like, a circulating system without air and impurities is obtained under the condition of not adopting a traditional filtering mode, and the problems of resistance addition, blockage and frequent maintenance caused by using a traditional filter screen are avoided, so that the water system can conditionally realize energy-saving operation. The spiral fin type separation device 2 in the separator cylinder 1 adopts a shape that a tooth-shaped fin is inclined into a propeller, and when circulating water transversely sweeps across a spiral fin structure, a relatively static area formed by the blades tangentially guides bubbles to move upwards and impurities to move downwards.

Specifically, when air and impurities flow through the separator along with circulating water, on one hand, the volume expansion and the speed reduction are realized, on the other hand, the propeller-shaped structure in the separator provides tangential power required by separation, and a plurality of relatively static detention zones are formed. In this stagnant zone, the gas bubbles can rise and collect at the top and exit the system through the exhaust valve 3, and fine particulate impurities can settle to the bottom of the cylinder, which unique separation principle ensures that gas and impurities are separated efficiently.

In the above embodiment, preferably, a plurality of rows of propeller-shaped structures are arranged in the fin-type separation device 2, and the plurality of rows of propeller-shaped structures are arranged inside the cylinder 1 in parallel in the up-down direction according to a preset interval, so as to further improve the filtration efficiency. The spiral fin type separating device 2 adopts a stainless steel belt with the thickness of 0.5 mm to be directly processed into a finished product after passing through a tooth punching machine and an automatic winding machine, and is simple and rapid. In addition, the free-state toothed fins have good elasticity, can generate axial shaking and tangential optional installation along the guide rod under the impact of water flow, can well prevent the attachment of impurities and bubbles, and improve the settling speed of the impurities and the rising speed of the bubbles.

In the above embodiment, preferably, the water inlet 11 and the water outlet 12 are located on the same horizontal line in the up-down direction of the cylinder 1, the water inlet 11 and the water outlet 12 are located on the upper portion of the cylinder 1 and serve as impurity separators, the water inlet 11 and the water outlet 12 are located on the lower portion of the cylinder 1 and serve as air separators, and the water inlet 11 and the water outlet 12 are located in the middle portion of the cylinder 1 and serve as air and impurity separators.

In the above embodiment, preferably, the impurity separator is installed at a low point of the facility pipeline and/or at an inlet of the facility, and the air separator is installed at a high point of the facility pipeline and/or at a high temperature of the facility pipeline.

Specifically, since the solubility of air in water decreases with increasing water temperature and bubbles accumulate toward high points, the bubble separator is mainly installed at the high temperature of the secondary side outlet water and the high point of the pipeline, so as to remove the newly separated gas in water. Because the impurities with high density are easy to gather at the low point of the system and are easy to enter equipment and dead angles of pipelines along with water flow, the impurity separator is arranged at the low point of the system and the inlet of the equipment to remove the impurities.

That is, an air separator is rotated up and down by 180 degrees, and the exhaust valve 3 and the blow-down valve 4 are exchanged to be used as an impurity separator. When the air separator cannot be installed at the high point, the bubble and impurity separator is suggested to be adopted at the low point, free bubble gas in water is discharged as far as possible, the quantity of accumulated gas at the top of the pipeline is reduced, and the accumulated gas is discharged through the top automatic exhaust valve 3.

In the above embodiment, preferably, one end of the blowoff valve 4 of the cylinder 1 is provided with a blind pipe, and the dry magnetic rod can be inserted into or pulled out of the blind pipe. The dry magnetic rod is inserted into the blind pipe, so that the magnetism can be enhanced, rust impurities can be adsorbed and collected, and the slag removal effect is enhanced.
