Abstract
The utility model discloses a novel electrical heating anti-freezing device of an internal-circulation sealing water cooling system. The device comprises a blower, a spraying heat, a circular copper coil, a spraying water pump, a corrosion-resistant electrical-heating pipe, a temperature-measurement thermocouple head and a high-precision temperature controller, wherein inner-circulation water is circulated in the copper coil, the heat of a pipe wall is discharged through the blower arranged at the top of the system after the heat of liquid is absorbed by the outer wall of the copper coil, when the temperature of the inner-circulation water rises (the temperature is higher than a set temperature), a spraying system is started automatically for cooling, external-circulation spraying water is sprayed on the outer surface of a hot and humid pipe wall to form a water film, the external-circulation spraying water absorbs the heat, becomes vapor, is evaporated and is brought away by flow gas, and the water which is not evaporated drops in a water-collecting groove arranged on the lower portion of the system and is used circularly. The device is simple, easy to implement, stable and reliable, has practicability and generality, can be widely used in sealing water cooling systems with various specifications, solves the anti-freezing problem fundamentally and enlarges the usage range of sealing water cooling systems.
Description
Technical field
The utility model relates to the closed water-cooling system of a kind of interior circulation, is specifically related to the novel electrical heating antifreezing device of a kind of interior closed water-cooling system of circulation.
Background technology
In the closed water-cooling system of circulation be to be used for medium-high frequency induction heating equipment water-cooled but or the professional cooling system of other liquid cools.Its operation principle is that interior recirculated water circulates in copper coil pipe, and the liquid heat is discharged the tube wall heat through the blower fan at system top after being absorbed by copper coil pipe outer wall; When interior circulating water temperature raises (temperature that is higher than default); Automatically start the spray system cooling, the outer circulation shower water is sprayed on the damp and hot outer surface of tube wall and forms moisture film, and heat absorption becomes the steam evaporation and taken away by flowing gas; The water droplet that is not evaporated then falls in the water leg of system bottom, recycles.Fluid in the coil pipe is closed circulation, consumes minimumly, and the consumption of shower water also is merely the 1-2 ‰ of specific discharge.But the water temperature of the closed water-cooling system of interior circulation is wanted 5-35 ℃, and environment temperature bronze pan tube bursting by freezing problem occurred generally at-5--30 ℃ when arrived winter, and the antifreeze problem scheme of present solution is the industrial alcohol of adding 30%.The maximum defective of this kind scheme is to have tangible disaster hidden-trouble; The supercooled water alcohol volatilization burning that leaks outside once took place in certain electric furnace factory, the major accident of burning apparatus and factory building, therefore; The structure of the closed water-cooling system that must internally circulate is improved, and fundamentally solves antifreeze problem.
The utility model content
The utility model mainly provides a kind of simple and practical, novel electrical heating antifreezing device of the closed water-cooling system of interior circulation of being convenient to operate.
The novel electrical heating antifreezing device of the interior closed water-cooling system of circulation comprises blower fan, spray head, the copper coil pipe of circulation, spray water pump, anti-corrosion electric heating tube, temperature thermocouple head, high accuracy temperature controller; Interior recirculated water circulates in copper coil pipe, and the liquid heat is discharged the tube wall heat through the blower fan at system top after being absorbed by copper coil pipe outer wall; When interior circulating water temperature rising promptly is higher than the temperature of default; Automatically start the spray system cooling, the outer circulation shower water is sprayed on the damp and hot outer surface of tube wall and forms moisture film, and heat absorption becomes the steam evaporation and taken away by flowing gas; The water droplet that is not evaporated then falls in the water leg of system bottom, recycles.
As a kind of technological improvement, the utility model has increased the electrical heating antifreezing device, has solved the winter temperature problem that causes the bursting by freezing of copper coil pipe on the low side.This electrical heating antifreezing device is made up of gauge tap, high accuracy temperature controller, anti-corrosion electric heating tube, A.C. contactor; Adopt control device and performer to divide body structure; Control device is installed in the control cabinet, and the anti-corrosion electric heating tube is installed in the water leg middle and lower part.High accuracy temperature controller is installed in the water leg bottom, and the water temperature of coming the detected set tank is when water temperature in the water leg is lower than lower limit (as 5 ℃); Temperature controller XMT1 action; Its normal opened contact is closed, and A.C. contactor KM1 coil gets electric adhesive, and the anti-corrosion electric heating tube begins heat temperature raising; When water temperature in the water leg reaches upper limit design temperature (as 15 ℃); XMT1 breaks off; KM1 coil blackout, anti-corrosion electric heating tube stop heating, and water temperature is in the antifreeze temperature range of setting in the control water leg that so moves in circles; Control the spray water temperature with this, reach the purpose that prevents that copper coil pipe from freezing and ftractureing.
Because this electrical heating antifreezing device is simple, reliable and stable, has practicality, versatility, can seal extensive use on the water-cooling system at different size, has fundamentally solved antifreeze problem, so enlarged the use zone of sealing water-cooling system.
