Shown in Figure 4 is the 3rd embodiment of liquefied gas evaporator of the present invention, and this embodiment has disposed a plurality of heat exchangers 22.In addition, connecting on the bottom and the liquid gas supply pipe 28 between each heat exchanger 22 of liquified gas container 21, be provided with switch valve 40 at the entrance side of each heat exchanger 22.In addition, each fuel feed pipe of the outlet side 22a of each heat exchanger 22 is connected with 1 fuel feed pipe 39, has pressure detector 41 on this fuel feed pipe 39.Be sent to controller 42 by pressure detector 41 detected signals, carry out the beginning of burning of the switching of switch valve 40 and catalytic combustion system 24 and the control that stops by this signal.
In addition, temperature-difference power generation module 43 is close to and is clipped between each heat exchanger 22 and the heater 23.
Below, the action of the device for gasifying liquefied gas of present embodiment is described.User's operation control 42, of opening switch valve 40 is from the liquid of liquid gas supply pipe 28 heat exchanger 22 supply liquefied gas.Simultaneously, the burning of the catalytic combustion system 24 that beginning and this heat exchanger 22 are corresponding.Catalytic combustion sends heat and is passed to heat exchanger 22, and the liquefied gas of the liquid state of supplying with from liquid gas supply pipe 28 begins gasification.As a result, pressure detector 41 detected pressure rise.
When above-mentioned catalytic combustion system 24 took fire, the generating of temperature-difference power generation module 43 also began.
In the controller 42 of Shi Yonging microcomputer is housed in the present embodiment, microcomputer has pressure detector 41 detected pressure and a reference value is compared, and according to the control program of the platform number of the heat exchanger 22 of this comparative result decision carrying out work.That is, when the reference pressure that has than microcomputer when this detected pressures is low, promptly, control, make it open the 2nd switch valve 40 automatically in the still more weak occasion of the firepower of burner 33.Like this, the quantity of the heat exchanger 22 by increasing work successively is in the pressure reference value that microcomputer has pressure detector 41 detected pressure.Like this, can adjust the quantity of the heat exchanger 22 of work, supply with the gasification liquefied gas of authorized pressure according to the requirement of temperature and burner 33.
In the above description, the structure of controller 42 as dress microcomputer in a kind of is illustrated, but also can show reference pressure at for example controller 42, pressure and this reference pressure that the user detects with visual comparative pressure detector 41, when the detected pressures of pressure detector 41 is low, operate, with the platform number of the heat exchanger 22 that increases work.
As described above, according to present embodiment, its structure is: heat exchanger 22 is for a plurality of, in the way of the liquid gas supply pipe 28 of the catalytic combustion system 24 that connects liquified gas container 21 and each heat exchanger 22, switch valve 40 is set, have and accept to be located at the signal of the pressure detector 41 on the fuel feed pipe 39 and the controller that above-mentioned switch valve 40 is carried out open and close, like this, just having realized can be according to temperature or according to the liquefied gas evaporator of the heat exchanger quantity of the gas pressure adjustment work of the kind of burner and requirement.
Shown in Figure 5 is the 4th embodiment of liquefied gas evaporator of the present invention, and in this embodiment, the heat exchanger 22 of a plurality of adjacency alternately connects outlet and inlet, arranged in series.In addition, on above-mentioned a plurality of heat exchangers 22, Temperature Detector 44 is set respectively, is provided with fuel cock valve 30 at the entrance side of being arranged to incorporate each catalytic combustion system 24 with each heat exchanger 22.In the present embodiment, the microcomputer of adorning in controller 42 has is accepted the signal of Temperature Detector 44 and is carried out the control program of each switch valve 30 of switch.In other words each switch valve 30 of switch is to the beginning of the burning of each catalytic combustion system 24 and stop to control.
Below, the action of the liquefied gas evaporator of present embodiment is described.In winter, when using burner 33,, can not supply with enough gasification liquefied gas to burner 33 sometimes because the heat of gasification of liquefied gas descends the temperature of liquified gas container 21 and heat exchanger 22.
Each heat exchanger 22 of the liquefied gas evaporator of present embodiment is provided with Temperature Detector 44, and the detected temperatures signal of this Temperature Detector is delivered to controller 42.Controller 42 is accepted the said temperature signal, opens in the switch valve 30, and catalytic combustion system 24 takes fire.Because descending, the temperature of heat exchanger 22 is to produce, so in the present embodiment, the catalytic combustion system 24 of Qu Donging at first is near liquified gas container 21 by heat exchanger near liquified gas container 21 1 sides.The heat that this catalytic combustion produces is delivered to heat exchanger 22, promotes the gasification of liquefied gas.At this moment, when the scarce capacity of the heat exchanger 22 of above-mentioned driving, then the temperature of the 2nd heat exchanger 22 is owing to the heat of gasification of liquefied gas descends.The Temperature Detector 44 that is installed on the 2nd heat exchanger 22 detects this temperature decline situation, and controller 42 is then opened the switch valve 30 of the 2nd catalytic combustion system 24, and catalytic combustion system 24 takes fire.Like this, when the scarce capacity of gasification,, can supply with enough gasification liquefied gas to burner 33 by the platform number of the heat exchanger 22 that increase to drive successively.
In addition, when the spent gas amount of burner 33 descended, the heat of gasification of liquefied gas tailed off, and the temperature of heat exchanger 22 rises.When Temperature Detector 44 detected this temperature rising, controller 42 cut out switch valve 30, catalytic combustion system 24 burn-outs.At this moment, it is opposite with the occasion of spent gas amount increase that the temperature of heat exchanger 22 rises, and taken place by the heat exchanger away from liquified gas container 21.For this reason, in the present embodiment, the catalytic combustion system that stops at first from aerosol container 21 farthest.
As described above according to present embodiment, its structure is: controller 42 accepts to be located at the signal of the Temperature Detector 44 on the heat exchanger 22, open and close switch valve 30, begin or stop the burning of catalytic combustion system 24, like this, having realized can be according to temperature or according to the liquefied gas evaporator of the heat exchanger quantity of the pressure adjustment work of the desired liquefied gas of kind of burner.
