The purpose of this utility model is in that to provide the sour method composite heat transfer high-efficient liquid ammonia evaporator that a kind of vaporization efficency is high, ammonia output is stable, quality of filling gas is good.
In order to reach object above, this utility model be the technical scheme is that a kind of sour method composite heat transfer high-efficient liquid ammonia evaporator includes being provided with the housing of water inlet pipe and outlet pipe, described water inlet pipe and outlet pipe are connected to the two ends of housing, being provided with upper spacer and lower clapboard in the inner chamber of housing, described upper spacer is cone structure；Between upper spacer and lower clapboard, being provided with heat exchange coil and return duct in the inner chamber of housing, the upper/lower terminal of described return duct extends through and is inserted on upper spacer and lower clapboard；Housing above upper spacer is provided with ammonia delivery outlet；Being provided with the liquefied ammonia input pipe of connection heat exchange coil lower end on housing between upper spacer and lower clapboard, the upper end of heat exchange coil is run through and is inserted on upper spacer.
Hull outside below lower clapboard is provided with high temp jacket, and described high temp jacket is provided with high-temperature inlet water mouth and high-temperature tempering mouth.
Water inlet pipe is provided with inlet flow rate and regulates device, outlet pipe is provided with rate of discharge and regulates device；Ammonia delivery outlet is provided with temperature sensor and pressure transducer；One of them signal output part of described temperature sensor and pressure transducer is connected to inlet flow rate and regulates the positive feedback of device through controlling device and control end, and the signal output part of another sensor is connected to rate of discharge and regulates the positive feedback of device through controlling device and control end.
The beneficial effects of the utility model are in that: this vaporizer vaporization efficency is high, ammonia output is stable, quality of filling gas is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of sour method composite heat transfer high-efficient liquid ammonia evaporator includes the housing 3 being provided with water inlet pipe 1 and outlet pipe 2, hot water inputs in housing 3 from water inlet pipe 1, and the water after heat exchange is discharged from outlet pipe 2.Described water inlet pipe 1 and outlet pipe 2 are connected to the two ends of housing 3, are provided with upper spacer 4 and lower clapboard 5 in the inner chamber of housing 3, and the inner chamber of housing 3 is separated into three spaces；Described upper spacer 4 is cone structure；Between upper spacer 4 and lower clapboard 5, being provided with heat exchange coil 6 and return duct 7 in the inner chamber of housing 3, the upper/lower terminal of described return duct 7 extends through and is inserted on upper spacer 4 and lower clapboard 5, links up the space of upper spacer more than 4 and the space of lower clapboard less than 5；Housing 3 above upper spacer 4 is provided with ammonia delivery outlet 8；Being provided with the liquefied ammonia input pipe 9 of connection heat exchange coil 6 lower end on housing 3 between upper spacer 4 and lower clapboard 5, the upper end of heat exchange coil 6 is run through and is inserted on upper spacer 4.Liquefied ammonia is input to heat exchange coil 6 from liquefied ammonia input pipe 9, after heat exchange coil 6 heat exchange, vaporization becomes ammonia, discharge through upper spacer 4 and ammonia delivery outlet 8, in the process, the a small amount of liquid ammonia do not vaporized is pooled in return duct 7 through the upper spacer 4 of taper, enters the space below lower clapboard 5 through return duct 7.
Housing 3 arranged outside below lower clapboard 5 has high temp jacket 10, and described high temp jacket 10 is provided with high-temperature inlet water mouth 11 and high-temperature tempering mouth 12.High temp jacket 10 passes into the hot water that temperature is higher, enters ammonia delivery outlet 8 through return duct 7 after promoting the liquid ammonia vaporization of backflow and discharge.
It addition, be provided with inlet flow rate on water inlet pipe 1 to regulate device 13, outlet pipe 2 be provided with rate of discharge and regulate device 14；Ammonia delivery outlet 8 is provided with temperature sensor T and pressure transducer P；Described temperature sensor T and pressure transducer P one of them signal output part through control device be connected to inlet flow rate regulate device 13 positive feedback control end, the signal output part of another sensor through control device be connected to rate of discharge regulate device 14 positive feedback control end.Described inlet flow rate regulates device 13 and rate of discharge adjustment device 14 is the valve with electric control gear.
During use, if temperature sensor T and pressure transducer P detects that temperature, pressure exceed standard, then by controlling the aperture of device adjustment inlet flow rate adjustment device 13 and rate of discharge adjustment device 14, adjust speed and the pressure of current, it is achieved automatically control.Temperature sensor T and pressure transducer P can adopt electronic sensor, it would however also be possible to employ mechanical sensor, controls device and the signal of sensor is changed into the acceptable signal form of flow regulator, be then passed to corresponding flow regulator.Pressure transducer P is to the control principle of flow regulator ibid.Control device and circuit structure can have multiple known technology, do not describe one by one at this.
