Background technique
Vaporizer is as being a kind of industry and civilian cryogenic liquide vaporising device, and effect is the gas that liquid gas is converted into gaseous state.Cryogenic liquid vaporizer is as conventional a kind of vaporizer, be generally divided into three kinds, empty bath formula vaporizer, electric heating water bath vaporizer and steam heating type vaporizer, but these three kinds of cryogenic liquid vaporizer exists following technological deficiency:
(1) bathe formula vaporizer about sky, although have without external energy, the advantage of energy-conserving and environment-protective, this vaporizer volume is large, very easily influenced by ambient temperature, and gas outlet temperature fluctuation is larger and wayward.
(2) about electric heating water bath vaporizer, although have advantages of that volume is little and convenient mobile, this vaporizer requires power larger for ABAP Adapter, can not meet the requirement of energy-conserving and environment-protective, in addition, water-bath type structure causes temperature to regulate control hysteresis serious and insensitive.
(3), about steam heating type vaporizer, although have advantages of that volume is little, the thermal efficiency is high, this vaporizer is subject to external steam resource limitation and causes specific environment to use, poor practicability.
Summary of the invention
The utility model in order to solve large, the inconvenient vehicle-mounted mobile of existing cryogenic liquid vaporizer volume, efficiency is low, evaporating capacity is little, the uncontrollable technical problem of outlet nitrogen temperature, provide a kind of volume little, facilitate vehicle-mounted mobile, efficiency is high, evaporating capacity is large, export the direct-fired cryogenic liquid vaporizer that nitrogen temperature can accurately be controlled.
The utility model provides a kind of direct-fired cryogenic liquid vaporizer, comprise thermal-insulating body, burning machine device, fuel supplying device and control box, burning machine device is located at the intracavity bottom of thermal-insulating body, and the inner chamber top of thermal-insulating body is provided with set of heat exchange tubes, set of heat exchange tubes and burning machine device it
Between be provided with flame distributor, the top of thermal-insulating body is provided with ventilating fan, fuel supplying device and control box are located at the side of thermal-insulating body, burning machine device, fuel supplying device and ventilating fan are connected with control box respectively; Set of heat exchange tubes is provided with outlet and entrance, and outlet and entrance are located at thermal-insulating body outside.
Preferably, burning machine device comprises oil pump, firing chamber and burning machine nozzle, and outlet is connected with outlet(discharge) flange, and entrance is connected with inlet flange.
The beneficial effects of the utility model are, volume is little, facilitate vehicle-mounted mobile, efficiency is high, evaporating capacity is large, outlet nitrogen temperature is controlled.
Lift a concrete effect example, on probation in the time that the defeated Gas Company of long celebrating " middle silver-colored line " is stopped using oil transport pipeline displacement of reservoir oil displacement by Wugong County Jia Ying gas Co., Ltd in October, 2012, field working conditions requires liquid nitrogen vaporization amount to be 4800 cubes ms/h, it is 4 MPas that pressure requires, nitrogen temperature is 10～20 ℃, traffic requirement is 4800 cubes of ms/h of left and right, and pipeline total length 113.7 kms, require to establish the construction of 4 construction point contiguous segmentations according to pipeline valve chamber layout.For meeting construction requirement, construction party uses the present invention separately to join three cryogenic liquid pumps and one of generator set has carried out tentative operation.Through overtesting, discovery and former construction equipment relatively have the following advantages:
(1) direct-fired cryogenic liquid vaporizer volume of the present utility model is little.With a pickup truck loading 100kw generator (containing frequency variator, being mainly used in cryogenic liquid pump group), cryogenic liquid pump group (power is 55kw), one, a vaporizer of the present utility model (power is 1kw); And original equipment uses two decometer cars to load, one, shipment 180kw generator, one of electric control cubicle, cryogenic liquid pump group (power is 55kw) and one of a water-bath type electric heating carburetor (power is 50kw), another chassis shipment air temperature type vaporizer scene reconnects.Visible direct-fired cryogenic liquid vaporizer volume of the present utility model is little.
(2) temperature adjustment is accurate in time.In the time that temperature need to be adjusted, direct-fired cryogenic liquid vaporizer of the present utility model is just adjusted oil pump, accurately adjusted in real time in time nitrogen outlet temperature, and original equipment is adjusted and is observed water temperature after water-bath type electric heating carburetor electric current and taper to 30 minutes ability of constant need and determine nitrogen outlet temperature.
(3) consume less, freight is low, business efficiency is high.Using the liquid nitrogen fuel consumption (comprising generator and this product burning oil) of the device construction equal number of the direct-fired cryogenic liquid vaporizer of model utility is 2/3 of former technological scheme, has greatly saved fuel oil and freight.
(4) compare with former technological scheme, equipment fixed investment is little, and operating cost is low.
(5) of many uses: in oil, rock gas, shale gas exploitation pressure break, the pressure testing of oil and gas pipelines nitrogen, displacement, it is multi-field easy to use that construction etc. is speedily carried out rescue work, overhauled to field fuel-firing gas-firing line equipment, and practicability is very strong.
The further feature of the utility model, by the description of following embodiment, is clearly recorded.
