Description
Technical field
The present invention relates to a kind of miniature movable type skid flashed vapour (BOG) and reclaim compressed natural gas (CNG) device.
Background technique
Along with oil-gas price widens the in-depth with clean energy resource policy further, CNG has become a kind of optimal automobile-used alternative energy source, and its application technology reaches its maturity through many decades development.The features such as it is low that it has cost, high efficiency, pollution-free, and use safety is convenient, demonstrate powerful development potentiality just day by day.CNG filling station is generally divided into three fundamental types, namely fills type fast, and common (at a slow speed) fills and both hybrid type.CNG is also applied to gas cause, particularly resident living fuel.Along with the raising of living standards of the people and the enhancing of environmental consciousness, the demand of most of city to rock gas obviously increases.Rock gas (pipe natural gas) is also greater than industrial fuel as the economic benefit of domestic fuel.LNG fill tank car when filling in general first emptying tank car remaining BOG reduce tank internal pressure, also very large owing to filling the more total amount of dropping a hint of tank car, therefore reclaiming the BOG filled in tank car has very large meaning for raising combustion gas utilization efficiency.Measure very little because separate unit fills the BOG had in tank car, arranging fixing recovering device can not move, and is not suitable for this transition production status frequently.Skid-mounted device is used to replace fixing device then can solve transition problem frequently very well.
Summary of the invention
The present invention seeks to: be to provide a kind of miniature movable type skid BOG to reclaim CNG device.
The technical solution used in the present invention is: in steel structure frame, be provided with knock out drum, BOG heat exchanger, empty temperature recuperator, water-bath recuperator, CNG air compressor; Be provided with suction line in the middle part of knock out drum, knock out drum top is provided with outlet line; Knock out drum outlet line is connected to the import of BOG heat exchanger; The gaseous phase outlet pipeline of BOG heat exchanger is connected with the suction port of sky temperature recuperator, and empty temperature recuperator outlet line is connected with water-bath recuperator suction port; Water-bath recuperator gaseous phase outlet pipeline connects with CNG suction port of compressor, and CNG compressor outlet connects with BOG heat exchanger inlet line.
Steel structure uses H profile steel welding, and H profile steel is provided with equipped instrument perforate and appliance wiring groove box.
Steel structure size can adjust according to instrument size.
The invention has the beneficial effects as follows: BOG gas is recycled into the integrated one-tenth sled of CNG device, be conducive to tackling the frequent transition in production process, the major part of dropping a hint filling tank car can be recycled into CNG, the present situation filling tank car frequent emptying BOG gas waste resource and befouling environment can well be solved.
Accompanying drawing explanation
Fig. 1 is the axonometric drawing that BOG reclaims CNG sled;
Fig. 2 is the plan view that BOG reclaims CNG sled;
Wherein E-1100BOG heat exchanger, the empty warm recuperator of E-1101, E-1102 water-bath recuperator, V-1100 knock out drum, C-1100CNG compressor, 1 steel structure, 2-BOG gas enters knock out drum pipeline, 3-knock out drum top BOG gives vent to anger pipeline, the empty warm recuperator entrance of 4-, the empty warm recuperator outlet line of 5-, 6-water-bath recuperator suction port, 7-water-bath recuperator gaseous phase outlet pipeline, the water inlet pipe line of 8-water-bath recuperator, 9-water-bath recuperator water outlet pipeline, 10-CNG suction port of compressor, 11-CNG compressor outlet, 12-CNG hot gas enters the suction line of BOG heat exchanger, 13-CNG virgin gas pipeline, 14-BOG heat exchanger air inlet, the gaseous phase outlet pipeline of 15-BOG heat exchanger.
Embodiment:
Technical characterstic of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of miniature movable type skid BOG reclaims CNG device, is provided with V-1100 knock out drum, E-1100BOG heat exchanger, E-1101 empty warm recuperator, E-1102 water-bath recuperator, C-1100CNG air compressor in steel structure frame; Knock out drum (V-1100) middle part is provided with suction line (2), and knock out drum (V-1100) top is provided with outlet line (3); Knock out drum outlet line (3) is connected to BOG heat exchanger (E-1100) import (14); The gaseous phase outlet pipeline (15) of BOG heat exchanger is connected with the suction port (4) of sky temperature recuperator (E-1101), and empty temperature recuperator outlet line (5) is connected with water-bath recuperator (E-1102) suction port (6); Water-bath recuperator gaseous phase outlet pipeline (7) connects with CNG compressor (C-1100) entrance (10), and CNG compressor outlet (11) connects with BOG heat exchanger inlet line (12).
Steel structure uses H profile steel welding, and H profile steel manufactures perforate before dispatching from the factory, and equipped instrument and appliance wiring groove box before welded steel strueture, steel structure size can adjust according to instrument size.
All devices is all arranged on steel structure one deck; BOG gas through knock out drum (V-1100) suction line (2) by entering knock out drum (V-1100) in the middle part of knock out drum, BOG heat exchanger is entered from knock out drum (V-1100) top exit pipeline (3), enter the CNG hot gas heat exchange of BOG heat exchanger with pipeline (12) in BOG heat exchanger, the BOG gas heated up through heat exchange enters empty temperature recuperator continuation intensification through the gaseous phase outlet pipeline (15) of BOG heat exchanger, and CNG gas enters CNG virgin gas pipeline (13); The BOG gas heated up through re-heat enters water-bath recuperator through sky temperature recuperator outlet line (5); BOG gas heats up further with water heat exchange in water-bath recuperator, water-bath recuperator water inlet pipe line (8), water outlet pipeline (9), BOG gas after heat exchange enters CNG compressor pressurizes through water-bath recuperator gaseous phase outlet pipeline (7), and the water through heat exchange goes out water-bath recuperator by water-bath recuperator water outlet (9); CNG gas after boosting enters BOG heat exchanger through CNG compressor outlet (11).
Utilize device of the present invention, the production status that CNG is reclaimed in frequent transition can well be adapted to, the BOG gas filling about 70-80% in tank car can be recycled into CNG gas, greatly can improve the utilization ratio of the energy and can atmospheric pollution be reduced.
