Abstract
The utility model provides a vacuum degassing device. An air exhaust device of the vacuum degassing device specially used for a heating ventilation closed water system comprises a vacuum tank (1), a vacuum pump (2), a water level limiter (3), a pressure sensor (4), a water draining electromagnetic valve (5), a water supplementing electromagnetic valve (6), a water inlet flow limiter (7), a water outlet flow limiter (8), a pressure gauge (9), a gas outlet and inlet one-way automatic exhaust valve (10), a check valve (11), a filter (12), a control unit (13) and a ball valve (14). The vacuum degassing device can effectively remove gas inside the heating ventilation closed water system, enable the system to avoid the problems of gas etching and gas blocking caused by the gas, prolong the service life of the system, improve the running efficiency of the system and eliminate algae and bacteria growth, thereby enabling the system to be more energy-saving and environment-friendly in running.
Description
Technical field
The utility model belongs to the exhaust apparatus that a kind of specialty is used for the HVAC closed Water System.
Background technology
The heating more than 90% and the air conditioner water circulatory system, all be subjected to the puzzlement of air problem, a large amount of air that exist in the water system (free gas in the water and dissolved gas) will cause following series of problems: the harm of cavitation (in, the heat exchange efficiency that influences end-equipment and dehumidification function, corrosion and microorganism, noise pollution etc.Existing exhaust equipment, its exhaust mode adopt high point or end to install automatic exhaust steam valve or manual exhaust valve additional more, and can only get rid of the gas that is free in the pipeline peak, can't get rid of dissolved gas and dead angle place gas; Cause the system operation cost height, operational efficiency is low, service life is short.
According to Henry's law, gas is solubility and water temperature and pressure correlation in water, at a certain temperature, is directly proportional with the pressure of gas.Under certain pressure, water temperature reduces, and gas solubility increases, and water temperature raises, and gas solubility reduces.When the pressure that reduces the water surface, then can under low water temperature, gas soluble in water be separated out, thereby remove the gas in anhydrating.When water is under the negative pressure state, the boiling point of water can reduce, and molten tolerance also can reduce.
Summary of the invention
The utility model is exactly by producing vacuum, free gas in the water and solution gas are discharged, discharge system by exhaust outlet again, water after the degassing system of reinjecting, the water of these low gas content amounts is unsaturated water, gas is had high absorption, it with the gas in the absorption system to seek the air water balance.The vacuum type degasser repeats such periodic duty.So move in circles, all gas in the system water is removed.
Vacuum type degasser of the present utility model comprises: vacuum tank (1), vavuum pump (2), water level limitation device (3), pressure sensor (4), sluicing magnetic valve (5), moisturizing magnetic valve (6), flow of inlet water limiter (7), water flow limiter (8), Pressure gauge (9), put the unidirectional automatic exhaust steam valve of gas (10), check-valves (11), filter (12), control module (13) ball valve (14) into and form; It is fetched water from system through sluicing magnetic valve (5), flow of inlet water limiter (7), filter (12) by vacuum tank (1); Drawn water through check-valves (11), water flow limiter (8) and injected system from vacuum tank (1) by vavuum pump (2), described water level limitation device (3) is positioned at the medium position of vacuum tank (1) again.
Described vavuum pump (2), water level limitation device (3), pressure sensor (4), sluicing magnetic valve (5), moisturizing magnetic valve (6), flow of inlet water limiter (7) and (8) start and stop of water flow limiter and data read are all concentrated and are arranged in the control module (13).
Vacuum tank (1) in form vacuum negative pressure condition because flow of inlet water limiter (7) exists difference in flow to force with water flow limiter (8) this moment, vavuum pump (2) was out of service when the interior water level of vacuum tank (1) dropped to water level limitation device (3), be dissolved in the vacuum tank (1) that gas parses in the water from water under the effect of negative pressure, along with the interior water level of vacuum tank (1) rises, gas is discharged by the unidirectional automatic exhaust steam valve of anti-air inlet (10) that is located at vacuum tank (1) top; When if pressure sensor (4) detection system pressure is lower than setting value, moisturizing magnetic valve (6) opens and cuts out sluicing magnetic valve (5) simultaneously, vacuum tank (1) will be fetched water from the water source, after vacuum exhaust, mend system with vavuum pump (2), system pressure rises in the setting range, moisturizing magnetic valve (6) cuts out and opens sluicing magnetic valve (5) simultaneously, continues vent sequence.Thereby eliminated because of there being air in the system and perplexed our difficult problem for many years---cavitation (in, reduce end-equipment heat exchange and dehumidification function, generation corrosion and problems such as microorganism and noise pollution.
Description of drawings
Fig. 1 is composition of the present utility model and connection diagram.
The specific embodiment
As shown in the figure, the utility model comprises: vacuum tank (1) is fetched water from system through sluicing magnetic valve (5), flow of inlet water limiter (7), filter (12); Draw water through check-valves (11) from vacuum tank (1) by vavuum pump (2) again, water flow limiter (8), and injected system, vacuum tank (1) in form vacuum negative pressure condition because flow of inlet water limiter (7) exists difference in flow to force with water flow limiter (8) this moment, vavuum pump (2) was out of service when the interior water level of vacuum tank (1) dropped to water level limitation device (3), be dissolved in the vacuum tank (1) that gas parses in the water from water under the effect of negative pressure, along with the interior water level of vacuum tank (1) rises, gas is discharged by the unidirectional automatic exhaust steam valve of anti-air inlet (10) that is located at vacuum tank (1) top; When if pressure sensor (4) detection system pressure is lower than setting value, moisturizing magnetic valve (6) opens and cuts out sluicing magnetic valve (5) simultaneously, vacuum tank (1) will be fetched water from the water source, after vacuum exhaust, mend system with vavuum pump (2), system pressure rises in the setting range, moisturizing magnetic valve (6) cuts out and opens sluicing magnetic valve (5) simultaneously, continues vent sequence.
