Implement a kind of device for preventing natural gas pressure regulating device from freezing of the utility model, have the advantages that：
1st, the utility model carries out intensification heating before natural gas adjusting valve group to natural gas, it is ensured that by after regulating valve
Natural gas temperature is more than 5 DEG C, it is to avoid the situation that pipeline freezes and blocks pipeline and valve occurs.
2nd, the utility model is heated using plate solar heater to raw natural gas, can greatly save heating day
Fuel cost or the electricity charge that right gas is used.
3rd, solar energy heating circulation loop and combustion of natural gas heating system are used and connected and/or in parallel by the utility model
Mode is run, and the method for operation flexibly, can at utmost save gas fuel.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is a kind of structural representation of the device for preventing natural gas pressure regulating device from freezing of the utility model.
In figure：First Heat Exchanger 1, the second heat exchanger 2, pressure regulator valve 3, plate solar heater 4, storage tank 5, burner 6.
Specific embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed
Illustrate specific embodiment of the present utility model.
As shown in figure 1, the utility model prevent natural gas pressure regulating device freeze device include and high-pressure natural gas webmaster
Output end pass sequentially through the First Heat Exchanger 1 of pipeline connection, the second heat exchanger 2 and pressure regulator valve 3, pressure regulator valve 3 and mesolow day
The input connection of right tracheae.The device also includes heat cycles loop, and heat cycles loop includes passing sequentially through pipeline successively
Form closed circuit plate solar heater 4, storage tank 5 and First Heat Exchanger 1；The output end of high-pressure natural gas webmaster is changed with second
Burner 6 is connected with by pipeline between hot device 2.Wherein, between the output end of high-pressure natural gas webmaster and First Heat Exchanger 1,
Between the output end of high-pressure natural gas webmaster and the second heat exchanger 2, between the heat exchanger 2 of First Heat Exchanger 1 and second, second heat exchange
Valve is provided between device 2 and pressure regulator valve 3, between pressure regulator valve 3 and the input of mesolow natural gas tube；Plate solar adds
Between hot device 4 and storage tank 5, between First Heat Exchanger 1 and plate solar heater 4, the input of plate solar heater 4
Valve is provided between output end；Valve is provided between the output end and burner 6 of high-pressure natural gas webmaster.
Operation principle of the present utility model is as follows：
As shown in figure 1, the heat exchange of First Heat Exchanger 1, second successively of the high-pressure natural gas from upstream high gas distributing system
Device 2 and pressure regulator valve 3, use into mesolow gas distributing system for downstream user.On daytime, recirculated water is in plate solar heater
Heat temperature raising in 4, by storage tank 5 into high-pressure natural gas are heated in First Heat Exchanger 1, returns plate solar and adds after cooling
Recycled in hot device 4.Wherein, recirculated water is ordinary cycle water, can add antisludging agent according to actual conditions.Recirculated water is by too
Temperature after positive energy panel heater 4 is heated is 50~70 DEG C, is 40~50 by the natural gas temperature after First Heat Exchanger 1
DEG C, by into the temperature of mesolow natural gas being more than 10 DEG C after pressure regulator valve 3.It is 50,000 N.m with gas discharge3/ h is calculated,
In First Heat Exchanger 1, natural gas temperature rises about 30 DEG C, and hot water temperature declines about 30 DEG C, and use time is matched somebody with somebody in daily hot water storage
It is 14 hours, then needs to configure the volume for about 300m of hot water storage tank 53.When sunlight is weaker, if passing through First Heat Exchanger 1
When natural gas temperature cannot be heated into predetermined value, can now open the output end of high-pressure natural gas webmaster and burner 6 it
Between valve and start burner 6, a part of natural gas enters to be burnt in burner 6 and produces high-temperature flue gas, and high-temperature flue gas pass through
Into in the second heat exchanger 2, further natural gas is heated up to reach predetermined temperature.When overcast and rainy, then the sun
Energy panel heater 4 will be unable to work, the valve now closed between the output end and First Heat Exchanger 1 of high-pressure natural gas webmaster
And the valve between the heat exchanger 2 of First Heat Exchanger 1 and second, and open the output end and the second heat exchanger of high-pressure natural gas webmaster
Valve between 2, upstream high natural gas exchanges heat in being then directly entered the second heat exchanger 2 with the high-temperature flue gas that burner 6 is discharged.
