Description
Technical field
The utility model relates to a kind of heater, especially relates to a kind of carbon dioxide heater.
Background technology
At present, people have accumulated the heating means enriching exothermal gas and liquid substance at industrial circle, and the heating of carbon dioxide is exactly one of them.But in the introduction, the heating problems of carbon dioxide fails to solve very well always.In recent years, adopt the electric heater of electrical heating gaseous carbon dioxide to occur, but CO2 heater is not industrially used widely.Main cause is, adopts the direct-fired mode heat transfer efficiency of electrical heating to be restricted, and under gaseous condition, the uniformity of its heating and stability are all difficult to control, and gaseous state directly heats, and the amount of heating carbon dioxide does not increase.The situation that some industry carbon dioxide demands are large can not be met.On the net except the report of some carbon dioxide heating rods, do not see reasonably feasible carbon dioxide heating means and device, and some pertinent literatures report.Illustrate that the carbon dioxide heating of large discharge remains a difficult problem.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of carbon dioxide heater is provided, making carbon dioxide add heat can promote greatly, heating-up temperature energy stability contorting.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of carbon dioxide heater, is characterized in that, comprising:
Constant water bath box, for storing constant-temperature hot water;
Inside is full of the heat exchanger tube of liquid carbon dioxide, is arranged in constant water bath box, is heated by the liquid carbon dioxide in heat exchanger tube by hot water heat convection;
Replenishing water tank of water, is connected with constant water bath box, for controlling height of water level in constant water bath box;
Electric heater, is arranged in constant water bath box, to the hot water heating in constant water bath box;
Agitator, is arranged in constant water bath box, for ensure that the constant and even of water bath with thermostatic control the temperature inside the box.
Described heat exchanger tube is arranged in the middle part of constant water bath box, comprises symmetrical left side coil pipe and right side coil pipe.
Described agitator is arranged in the constant water bath box between left side coil pipe and right side coil pipe.
Described electric heater is provided with 4, is arranged in coil pipe upper and lower.Adopt the technical measures that electric heater multiple spot is arranged and agitator is challenged.Such as, the indivedual electric heater of suitable switch; Increase the stirring frequency of agitator; Supplement or discharge certain hot water etc.
Be provided with thermocouple thermometer in described constant water bath box, and Sewage outlet is set in bottom.
Described heat exchanger tube is imported and exported and is provided with upper flange and lower flange, is connected respectively with carbon dioxide holding tank and pressure-reducing valve.
The hot water of uniform temperature is heated by electric heater constant temperature, and by the stirring action of agitator, rapidly bottom hot water is mixed with top hot water, hot water transfers heat to the tube wall of heat exchanger tube, by the conductive force of tube wall, heat is finally passed to the liquid carbon dioxide of heat exchanger tube inside, carbon dioxide temperature is raised, flowed out from heat exchanger tube outlet by the carbon dioxide after heating.
This device, in whole heat transfer process, makes carbon dioxide all be in liquid flow regime, and hot water temperature controls at 60 ~ 80 degree, avoids a large amount of steam raising of steam and carbon dioxide to gasify in heat exchanger tube.
The utility model utilizes the method for electric heater heat hot water and heating liquid carbon dioxide, and the coefficient of heat transfer that make use of convective heat transfer liquid is far longer than the principle of gas converting heat coefficient.Like this when transmitting identical heat, greatly can reduce heat exchange area, easily realizing the big upgrade adding heat.Here need to explain, the liquid carbon dioxide of certain flow and pressure, after determining out temperature, its caloric receptivity is constant, so electrical heating input power substantially constant.Only have like this and consider the water temperature of constant water bath box and the relation of heating surface area.After heating surface area is determined, carbon dioxide caloric receptivity is just only relevant with water tank water temperature, and that is the height of water temperature determines carbon dioxide caloric receptivity.As long as regulate for this reason and keep water temperature just can ensure carbon dioxide recepts the caloric.
Compared with prior art, the utility model has the following advantages: the heating carrying out carbon dioxide in a large number continuously, when heat exchange area is certain, by increasing or reduce the temperature of water bath hot water, under ensureing carbon dioxide flow fluctuation situation, export the uniformity of carbon dioxide temperature.Heated by liquid towards carbon dioxide, decrease heat exchange area.Facilitate the layout of device, solve the technical problem that this area is thirsted for solving for a long time.
