Abstract
The utility model discloses a gas leak detection device, which utilizes the physical property that the liquefaction temperatures of water vapor and leaking process gas are different, concretely, water vapor is pumped into a cooling tube and is condensed by a cooling medium, then condensed fluid is collected and pumped into water, and leakage phenomenon of equipment is proved if bubbles appear on the water surface or sampling analysis is performed, so that the gas leak detection device plays a favorable protection role on safe operation and control of production equipment; and meanwhile, the gas leak detection device is convenient for an operator to operate and observe in the field, is not only accurate but also convenient and safe, and can be widely applied to the places such as a waste heat boiler, a steam heater and the like in the industries such as petrochemical industry, etc.
Description
Technical field
The utility model relates to a kind of gas leak detection device; Especially a kind of leakage detection apparatus of leakage that is mainly used in process gas (hydrogen, nitrogen) in the monitoring production of synthetic ammonia can be widely used in the places such as waste heat boiler, steam heater of industries such as petrochemical complex.
Background technology
Process gas in production of synthetic ammonia mainly refers to hydrogen, nitrogen, methane etc., and these gases all belong to inflammable, explosion hazard gases.Equipment is more and complicated in Ammonia Production, and high, medium and low voltage equipment is interweaved (not waiting from normal pressure to 32.0MPa pressure), and some equipment high, medium and low voltage is integrated in one; And processing medium is different, like the waste heat boiler in the ammonia synthesis system, walks about 320 ℃ of high pressure hydrogen and nitrogen gas, temperature in its tube bank; Pipe is leaked water outward, steam, in case in use hydrogen, nitrogen leak, can not in time find; High pressure is scurried low pressure, the danger of just might build the pressure, exploding.
The utility model content
In order to address the above problem; The utility model provides a kind of gas leak detection device; This gas leak detection device can be monitored the leakage of process gas in the production of synthetic ammonia (hydrogen, nitrogen); Avoid occurring security incident, can be widely used in the place such as waste heat boiler, steam heater of industries such as petrochemical complex.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of gas leak detection device; Have cooling tube and coolant medium container; In the said coolant medium container heat eliminating medium is housed; Said cooling tube is arranged in said coolant medium container and is immersed in said heat eliminating medium, and said cooling tube has steam inlet and condensate outlet, and said steam inlet connects the steam sampling mouth of heat transmission equipment.
Said cooling tube has at least one section spiral coil pipe that is immersed in the heat eliminating medium.
Said coolant medium container is uncovered tank.
Said uncovered tank has water inlet and overflow vent.
The beneficial effect of the utility model is: the described gas leak detection device of the utility model is a physical characteristics of utilizing water vapor different with the process gas condensing temperature of leakage; Water vapor is carried out condensation; Collect and feed condensed fluid in the water again; There is bubble to occur or is that provable this equipment has leakage phenomenon if find the water surface, good guaranteeing role has been played in the safe operation and the control of process units, be convenient to site operation personnel's operation simultaneously and observe through sampling analysis; Not only accurately but also convenient and safe, can be widely used in the place such as waste heat boiler, steam heater of industries such as petrochemical complex.
Description of drawings
Fig. 1 is the gas leak detection apparatus structure synoptic diagram of the utility model.
Embodiment
Embodiment: generally speaking, it is that high pressure is scurried low pressure that equipment take place to leak, and these equipment majorities are heat transmission equipment, has not only reclaimed heat but also byproduct steam.When process gass such as hydrogen, nitrogen bled vapour system, these process gass had incoagulability at water etc. during as heat eliminating medium, but water vapour is then different, when running into water etc. as heat eliminating medium, became liquid state from steam state.
According to the above-mentioned physical characteristics of gas, thereby produced the gas leak detection device of the utility model.
A kind of gas leak detection device; Have cooling tube 1 and coolant medium container 2, in the said coolant medium container heat eliminating medium is housed, said cooling tube is arranged in said coolant medium container and is immersed in said heat eliminating medium; Said cooling tube has steam inlet 11 and condensate outlet 12; Said steam inlet connects the steam sampling mouth of heat transmission equipment, and condensate outlet is taken over flexible pipes such as can adopting rubber, is convenient to observation and dismounting, sampling etc.
Said cooling tube has at least one section spiral coil pipe that is immersed in the heat eliminating medium.Cooling tube can be selected the material that is complementary for use according to processing medium and pressure rating;
Said coolant medium container is uncovered tank.Uncovered tank has water inlet 21 and overflow vent 22.Uncovered tank is a normal pressure, and plain carbon steel gets final product.
Be condensed into condensed fluid with heat eliminating medium in the cooling tube of elder generation with water vapor feeding the utility model gas leak detection device of heat transmission equipment; Said heat eliminating medium must possess simultaneously can be with water vapor condensation and can not be with two conditions of process gas condensation; Again condensed fluid is collected; Then condensed fluid analysis has been judged whether the process gas leakage phenomenon; This analytical approach has two kinds: a kind of is that condensed fluid is directly fed in the water, if the water surface has bubble to occur, then this heat transmission equipment place has process gas to leak; Another kind is that this condensed fluid is carried out sampling analysis.
The application of this gas leak detection device is following:
One, in the production of synthetic ammonia:
The steam heater steam (vapor) outlet of A, raw material gas purifying workshop section---pure hydrocarbonylation purification section, from equipment critical point 200---on the pipeline of 500mm.
Steam outlet on the waste-heat recoverer of B, ammonia synthesis workshop section, position and A are together.
Two, in the methanol production process:
Tube and shell type methanol synthesis converter drum steam outlet pipe place, position and A are together.
This gas leak detection device can be widely used in places such as the waste heat boiler, steam heater of industries such as petrochemical complex.This gas leak detection Unit Installation place can freely be confirmed according to on-site actual situations, but answer as close as possible sampling point position.
If monitor out the process gas leakage phenomenon at this gas leak detection device place; Need to stop or plan processing according to the size of leakage rate; Good guaranteeing role has been played in safe operation and control to process units, is convenient to site operation personnel operation simultaneously and observes, not only accurately but also convenient and safe.
