Description
Technical field
The present invention is a kind of natural gas line noise reduction, the anti-icing stifled device that reaches cold energy use.Relate to the pipe-line system technical field.
Background technique
Internal pressure-regulating valve place, field, natural gas line station is the main source of noise, and the noise that produces behind the common pressure regulator valve for the design of not eliminating the noise can reach more than the 100dB (A) through field measurement.Because can cause the stifled problem of pressure regulator valve ice after the defeated gas water content of institute is higher and ambient temperature is lowered the temperature, influence is carried.Temperature reduced after the natural gas via of being failed was crossed the pressure regulator valve step-down, and the cold energy that is produced if can be used, and can produce extra economic benefit.
The technology of taking the anti-icing stifled injection pipe of electric heating type is arranged at present, be characterized in spout surface uniform winding electric heating wire, injection pipe is formed the inner and outer pipes form by stainless steel outer tube and copper interior pipe, insulating is set between the inner and outer pipes, cold transmission with the outer high temperature media of cryogenic media and injection pipe in the pipe in reducing reduces the icing rate at spout place.When cryogenic media in the interior pipe when spout sprays direct ice making in water, because of the long-pending spout that causes of the embacle at spout place stops up, the electric heating wire that is wrapped in the spout surface is controlled by the cryogenic media flow switch, automatically energising heating, ice-melt rapidly, it is stifled to eliminate spout place ice, keeps spout unimpeded, makes the direct ice making of jet-type normally carry out.This technical pattern is simple and reliable, and is easy to use, and power consumption is few.This technology is used for the jet-type ice making, is not to be used to solve natural gas line pressure regulator valve place's noise and the stifled problem of ice.
Also having a kind of is the pressure relief valve testing apparatus of band noise reduction and safety protection case, and it comprises air compressor, surge tank, solenoid valve, pneumatic valve, controller, and described testing apparatus is provided with sound insulation safety protection case.
The characteristics of this technology are: 1. the Total Test condition meets technical requirementss such as JB/T7065-2004, JB/T7069-2004; 2. sensitive switch automatically resets and adopts the minitype pneumatic element design, can avoid the operator and be contacted by the trial target zero distance; 3. noise reduction safety protection effect obviously improves; 4. can one the screen multi-point monitoring, realize remote-controlled operation, reliable operation, simple and safe operation, rate of fault is low.This device is used for pressure relief valve test, is provided with sound insulation safety protection case, and is stifled and cold energy use is irrelevant with pipeline ice.
Summary of the invention
The objective of the invention is to invent a kind of elimination volute tongue controlled with the natural gas line pressure regulator valve within national Specification, sound deadening capacity is big, alleviate the stifled problem of ice, the cold energy use effect is obvious, do not influence the device of flow, simple installation, natural gas line noise reduction that cost is low, anti-icing stifled and cold energy use.
The invention discloses a kind of natural gas line pressure regulator valve place and carry out noise reduction, anti-icing method and the device that blocks up and carry out cold energy use.With pressure regulator valve and front and rear tube heating thereof, can prevent that stagnant ice is stifled; Cold water after the heat exchange can be used for indoor coolings such as air-conditioning; The heat exchange thermal insulation apparatus is wrapped in the body outside outward, can stop the transmission of noise to the pipeline outside again.
Formation of the present invention comprises flat heat exchange pipe 1, pressure regulator valve 2, overcoating 3, natural gas line 4, Constant pressure tank 5, recycle pump 6, water knockout drum 7, solar heater 8, work living area indoor cold supply system 9 in summer, gas heating furnace 10, water-collecting machine 11, inlet rock gas 12, export gas 13, low temperature water 14 and high-temperature water 15 as shown in Figure 1.By pressure regulator valve 2 two sections natural gas lines 4 are linked into an integrated entity, outside whole natural gas line 4 and pressure regulator valve 2, be surrounded by the flat heat exchange pipe 1 of overcoating 3; Between water knockout drum 7 and the water-collecting machine 11 and connect solar heater 8, work living area indoor cold supply system 9 in summer and gas heating furnace 10, water-collecting machine 11 has pipeline to connect a end to flat heat exchange pipe 1, the other end of flat heat exchange pipe 1 is received water knockout drum 7 after connecing recycle pump 6 by pipeline again, connects Constant pressure tank 5 in the inlet of recycle pump 6.
Wherein flat heat exchange pipe 1 is selected the red copper flat tube for use.
Principle:
Be tied with flat heat exchange pipe 1 on pressure regulator valve 2 and front and back natural gas line 4 outer walls thereof and carry out heat exchange, the water that in the flat heat exchange pipe 1 is certain flow rate is as heat transferring medium, with the natural gas line 4 of heating pressure regulator valve 2 and front and back thereof, improve valve body and tube wall temperature, reduce the stifled possibility of ice.Flat heat exchange pipe 1 closely is wrapped on pressure regulator valve 2 and the natural gas line 4 side by side, and skin is coated with overcoating 3 again, and this layer is respectively polyurethane heat insulation material, sound absorption and insulation material and galvanized sheet iron protective layer from inside to outside.
Natural gas line 4 tube walls of pressure regulator valve 2 and front and back thereof are heated, can be in pressure regulator valve 2 aperture etc. locate to destroy the stifled formation temperature of ice, the anti-icing stifled mode of this kind can be saved the natural gas burning amount in a large number compared to the mode of using water jacket furnace heating rock gas before pressure regulator valve.
The flat heat exchange pipe 1 of pipeline outer wall, sound absorption and insulation material can absorb obstruct to the noise at pressure regulator valve place, reduce the noise that outwards transmits.
The cold water that forms after the heat exchange in summer can be used for carrying out the radiation cooling of office area, and is aided with solar water heater and heats, and can switch when the stifled possibility of ice in winter strengthens and use gas heating furnace to improve water temperature.
Practical application shows, this silencer sound deadening capacity is big, alleviate the stifled problem of ice, the cold energy use effect is obvious, and it is low not influence flow, simple installation, cost.
The present invention both can be used for long defeated rock gas and had divided defeated station, can be used for city gas gate station again, was installed on internal pressure-regulating valve place, station.Domestic have many natural gas lines, and the rock gas pressure regulator valve of installing and using much all exists noise or the stifled problem of ice, if can promote, has a extensive future.
Sound deadening capacity of the present invention is big, alleviate the stifled problem of ice, the cold energy use effect is obvious, and it is low not influence flow, simple installation, cost.
