Abstract
The utility model is related to a kind of performance heater modules for preposition module.Including heat exchanger, hot water line and gas pipeline, wherein hot water line is made of water isolation valve I, II and water control valve I, II；Natural gas tube routing gas inlet to outlet sets gradually natural gas flowmeter, natural gas isolating valve and natural gas cut-out valve group, and two traditional shell-and-tube heat exchangers being installed in series are replaced in particular by a printed circuit board heat exchanger.The utility model technological process compared with general performance heater module is more succinct, due to the high reliability and design feature of printed circuit board heat exchanger, equipment, the leakage points such as installation liquid-level switch isolating valve, liquid-level switch, blowdown valve, natural gas bypass valve is no longer needed to greatly reduce.
Description
Technical field
The utility model belongs to heated by natural gas system regions, and in particular to a kind of performance heater for preposition module
Module.
Background technology
Preposition module is the process system of fuel gas disposal needed for the heavy duty gas turbine of plant gas, mainly by filtering,
Heating, steam-water separation function module composition, make the clean level of natural gas, temperature meet the needs of combustion engine.Performance heater mould
Block main function be exactly using high temperature medium-pressure boiler water in heat exchanger by heated by natural gas to after about 180 DEG C, be conveyed to combustion engine
Burning uses.
General design, as shown in Figures 1 and 2, performance heater module are exchanged heat by two horizontal shells being installed in series
The compositions such as device, valve, pipeline, instrument.Since the heat exchange area of needs is larger, so shell-and-tube heat exchanger appearance and size is larger,
Heavier-weight；Simultaneously because the characteristics of plant gas frequent start-stop, shell-and-tube heat exchanger easily occurs due to thermal force fatigue
Leakage, power plant on-line maintenance or must not reduce generating efficiency using cryogenic natural gas.
Invention content
Technical problem to be solved in the utility model is：The performance heater module appearance and size being typically designed is larger,
The problem of being easy to happen leakage.
The utility model is that technical solution used by solving its technical problem is to provide a kind of property for preposition module
It can heater module.The module is made of heat exchanger, hot water line and gas pipeline three parts, and the hot water line is located at
Exchanger heat water inlet side is provided with water isolation valve I and water control valve I, and the hot water outlet side of heat exchanger is provided with water management
Valve II and water isolation valve II；The gas pipeline be located at heat exchanger gas inlet side be provided with natural gas flowmeter and
The gas outlet side of natural gas isolating valve, heat exchanger is provided with natural gas cut-out valve group, using a printed circuit board
Heat exchanger substitutes two shell-and-tube heat exchangers being installed in series of traditional performance heater module.
Two shell-and-tube heat exchangers of core equipment of performance heater module are replaced with a printing electricity by the utility model
Circuit plate（PCHE）Heat exchanger simplifies technological process；Meanwhile the natural gas other than original preposition module is cut off into valve group, matter
Amount flowmeter is integrated in performance heater module.
Printed circuit board（PCHE）Heat exchanger is a kind of novel high-efficiency compact formula heat exchanger, and main heat exchange structure is not
It is traditional steel pipe, but steel plate.Every piece of plate both sides etch small flow of media channel, are welded using diffusion welding (DW) between plate and plate
It connects.Therefore circuit board type（PCHE）The coefficient of heat transfer of heat exchanger is far longer than traditional shell-and-tube heat exchanger, under identical thermic load, most
Small appearance and size can reach 15% or so of only shell-and-tube heat exchanger；And use is more reliable, is not susceptible to leak.

Specific implementation mode
The utility model is described further with specific embodiment below in conjunction with attached drawing.
It is Tthe utility model system schematic diagram and layout drawing as shown in Figures 3 and 4.The system is by heat exchanger, hot water line and day
Right air pipe three parts composition, the hot water line are located at exchanger heat water inlet side and are provided with water isolation valve I 1 and water control
The hot water outlet side of valve I 2 processed, heat exchanger is provided with water control valve II 6 and water isolation valve II 5；The gas pipeline position
Heat exchanger gas inlet side is provided with natural gas flowmeter 8 and natural gas isolating valve 7, the gas outlet one of heat exchanger
Side is provided with natural gas cut-out valve group 4, and a printed circuit board heat exchanger 3 is used to substitute traditional performance heater module
Two shell-and-tube heat exchangers being installed in series.
The utility model（Fig. 3）With originality energy heater module（Fig. 1）It is more succinct compared to technological process, due to printed circuit
Plate heat exchanger（PCHE）High reliability and design feature, it is no longer necessary to liquid-level switch isolating valve, liquid-level switch, blowdown are installed
Equipment, the leakage points such as valve, natural gas bypass valve greatly reduce.
Compare the utility model（Fig. 4）And originality energy heater module（Fig. 2）Layout drawing can be seen that the reality of module
It is arranged in length, is obviously reduced in broadband direction, and new performance heater module total weight reduces 50% or more.Meanwhile newly
Performance heater module will original natural gas flowmeter mounted on other positions, natural gas cut-out valve group both equipment collection
At coming in, make that Operation and Maintenance is more convenient, management is more concentrated.
