Description
Technical field
The utility model relates to gas-fired equipment technical field, particularly relates to a kind of CNG high-efficiency heat exchanger.
Background technology
CNG and compressed natural gas (Compressed Natural Gas is called for short CNG) are natural gas pressurization and store in a reservoir with gaseous state.Compressed natural gas is except with except the natural gas in oil field and gas field, can manually manufacturing biogas (main component is methane).Compressed natural gas is identical with the constituent of pipe natural gas, and main component is methane (CH4).CNG can be used for making LNG (Liquefied NaturalGas, i.e. liquefied natural gas), and this is that the vehicle of fuel is called NGV (NaturalGasVehicle) with CNG.
CNG gas station can be divided into three types according to site and function, is divided into normal station, CNG mother station, CNG substation 3 type.Normal station is that gas is got from pipe network by gas station, directly to vehicle aerating.Normal station equipment has ground high-pressure gas cylinder group (200 ~ 250kg), control system, filling machine, compressor sled block usually, and in general website, rush-harvesting and rush-planting filling machine 2 ~ 4 is established at station.CNG mother station is except the function of normal station, and CNG mother station also has other function, and namely add gas column to substation trailer aerating by being located in station, CNG can be transported to substation by substation trailer, to substation air feed.A refueling mother station can fill fortune gas bottle truck more than ten day, for periphery 4-6 air entraining substations.CNG substation mainly build the large inner city periphery of vehicle flowrate in, is mainly applicable to tubine performance difficulty, and uneconomical or existing gas supply capacity can not meet the website with gas needs of gas station, adopts the form of building air entraining substation to implement refueling.The capital equipment of CNG gas station comprises: gas-drying apparatus, compressor bank, caisson, inflation two priority classes dish, add gas column, gas selling machine etc.
Need fuel gas pipeline to carry out heat exchange intensification before gas pressure-reducing in heat exchanger, in order to ensure temperature rise effect, the volume of heat exchanger is larger often, heat transfer effect is better, this is because the volume of heat exchanger increases, just more fuel gas pipeline can be held therein, to increase heat-exchange time.The volume of heat exchanger is larger, can make troubles, add equipment cost for the installation of equipment and use.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of CNG high-efficiency heat exchanger.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of CNG high-efficiency heat exchanger, is characterized in that: comprise housing, described housing is provided with water inlet and delivery port, and the inside of housing is provided with at least one electric heater; The side of described housing is provided with the second entrance A and the first entrance B, and the opposite side of housing is provided with the first outlet C and second outlet D; Described first entrance B and first outlet C, described second entrance A and second outlet D is connected by respective independently heat exchanging pipe in the inside of described housing; Described second entrance A is connected by exterior line with the first outlet C.
The outside of described housing is also provided with steam vent.
Operation principle of the present utility model is: first, is made the inner filling water of housing, opening electric heater by water inlet; Combustion gas enters the first entrance B, then by heat exchanging pipe, combustion gas is heated up, then from the first outlet C out; Then, combustion gas enters the second entrance A, carries out secondary temperature elevation by combustion gas during heat exchanging pipe; Finally, combustion gas by the second outlet D out.The heat-exchanger rig that the utility model provides is provided with two entrances and two outlets, and its inside is provided with two and overlaps independently heat exchanging pipe; Combustion gas can carry out twice intensification heat exchange in a heat-exchanger rig, improves heat exchange efficiency, reduces equipment volume, decrease power consumption.

As shown in Figure 2, the side of described housing 1 is provided with the second entrance A and the first entrance B, and the opposite side of housing 1 is provided with the first outlet C and second outlet D; Described first entrance B and first outlet C, described second entrance A and second outlet D is connected by respective independently heat exchanging pipe in the inside of described housing 1; About the design of two heat exchanging pipes in the utility model, follow separate, to make full use of housing 1 inner space principle, have numerous embodiments in prior art, such as pipeline detours the inwall of housing 1, the S-type distribution of pipeline, pipeline in the shape of a spiral etc.
Further, described second entrance A and first outlet C be connected by exterior line, and can on exterior line mounted valve, pressure regulator, filter, flowmeter, thermometer or Pressure gauge etc.
In addition, the outside of described housing 1 is also provided with steam vent.
The idiographic flow of heat exchange operation is:
(1) inner filling water of housing 1 is made by water inlet 2, opening electric heater; Combustion gas enters the first entrance B, then by heat exchanging pipe, combustion gas is heated up, then from the first outlet C out;
(2) combustion gas enters the second entrance A, carries out secondary temperature elevation by combustion gas during heat exchanging pipe;
(3) combustion gas by the second outlet D out.
In sum, above-mentioned heat-exchanger rig is provided with two entrances and two outlets, and its inside is provided with two and overlaps independently heat exchanging pipe; Combustion gas can carry out twice intensification heat exchange in a heat-exchanger rig, improves heat exchange efficiency, reduces equipment volume, decrease power consumption.
