Description
Technical field
This utility model is related to a kind of electric heater for natural gas line of natural gas technical field.
Background technology
Natural gas is the relatively low gaseous fluid of ratio of viscosities, after natural gas is produced from gas well, purifies work through desulfurization dewatering etc.
Skill, then by pipe high-pressure transport, then by the way of step pressure reducing by reduced pressure to use safely scope, be then sent to
Downstream user.When by reduced pressure, what is be usually used is pressure regulator valve reducing pressure, but in downstream after pressure regulation throttling
Gas, temperature are reduced, and after gas enters pilot valve, throttle again, can produce larger temperature drop, therefore pilot valve in pilot valve
Gas temperature at valve port can fall too low, and be easy to ice stifled phenomenon when winter, temperature was low.In order to anti-stagnant ice is blocked up
Generation, at present in Long-distance Transmission Pipeline it is general using electric heater come heated natural gas, when using electric heater, by
Very high in electric heater working surface temperature, if inclusion of air system, high temperature heater (HTH) surface be enough to light explosive mixing
Thing, so as to cause blast.So, must assure that when when using electric heater to heated by natural gas miscellaneous without air in gas
Matter.
The content of the invention
This utility model purpose is to improve the efficiency of heating surface of natural gas electric heater and safety, there is provided Yi Zhongyong
It is in the electric heater of natural gas line, convenient to use, the efficiency of heating surface and safety can be improved.
The technical scheme adopted by this utility model is：
This utility model is a kind of electric heater for natural gas line, mainly by housing, insulation material, heating chamber,
Gas distributor, Imported gas, sewage draining exit, mixed flow room, anti-explosion terminal box, first class of protection switch, overtemperature prote switch, it is natural
Gas is exported and temperature detecting resistance is constituted.Electric heater left end is provided with mixed flow room, anti-explosion terminal box, first class of protection switch, overtemperature prote
Switch, gas outlet and temperature detecting resistance, right-hand member are provided with gas distributor and Imported gas, and middle part is heating chamber, sewage draining exit
Located at the middle part of electric heater.Insulation material is provided with inside electric heater, housing is connected with insulation material；Set at Imported gas
There is gas distributor, its effect is to enable heating chamber to be uniformly distributed in into the indoor natural gas of heating.Inside electric heater
Insulation material is provided with, housing is connected with insulation material；Gas distributor is provided with Imported gas, its effect is made into heating
Indoor natural gas can uniformly be distributed in heating chamber.First class of protection is switched and is connected with overtemperature prote switch, and its effect is the same day
When being so mixed with air or other impurities gas in gas, horse back disconnecting power switch plays a protective role.Anti-explosion terminal box is located at
The left end of electric heater, for the generation for preventing from exploding.
Advantage of the present utility model：Convenient to use, inside is provided with insulation material, 5 heating rods and overtemperature prote and opens
Close, significantly improve can the efficiency of heating surface and safety.
Description of the drawings
Fig. 1 is a kind of structural representation of the electric heater for natural gas line of this utility model.
Fig. 2 is Fig. 1 (A-A) sectional view.
In figure：1. housing, 2. insulation material, 3. heating chamber, 4. gas distributor, 5. Imported gas, 6. sewage draining exit, 7.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in figure 1, a kind of electric heater for natural gas line of this utility model, mainly by housing 1, insulation material
2nd, heating chamber 3, gas distributor 4, Imported gas 5, sewage draining exit 6, mixed flow room 7, anti-explosion terminal box 8, first class of protection switch 9,
Overtemperature prote switch 10, gas outlet 11 and temperature detecting resistance 12 are constituted.The electric heater left end is provided with that mixed flow room 7 is explosion-proof to be connect
Line box 8, first class of protection switch 9, overtemperature prote switch 10), gas outlet 11 and temperature detecting resistance 12, right-hand member is provided with gas distribution
Device 4 and Imported gas 5, middle part are heating chamber 3.
As shown in Figure 1 and Figure 2, specific heating process is：Natural gas is entered from Imported gas 5, through gas distributor
4 tailing edge inwall surroundings flow into heating chamber 3 and are heated, the heated natural gas at the gap of electrical heating original paper, are added natural gas
Heat heats up, and then bout flows into mixed flow room 7, from gas outlet 11 is flowed out after being mixed in mixed flow room 7.Go out in natural gas
It is provided with temperature detecting resistance 12 to detect the temperature of eluting gas at mouth 11, gas outlet 11 can be flowed by controlling temperature control instrument
The natural gas temperature for going out is controlled.First class of protection switch 9 and overtemperature prote switch 10 are provided with electric heater, work as electrical heating
When natural gas temperature in device reaches the temperature of 9 setting of first class of protection switch, in switch board, catalyst will be switched off, and heater stops
Heating；When natural gas temperature is less than design temperature, can recovery heating automatically.When the natural gas temperature in electric heater reach it is super
During warm 10 design temperature of protection switch, the air switch in controller will be automatically powered off, and electric heater stops heating at once, concurrently
Go out sound and light alarm；The dirt produced in whole electrical heating process will be excluded from sewage draining exit 6, i.e. electrical heating process terminates.
