The flue (1) and the cylinder body (2) adopt an integrated structure, and the cylinder body (2) is connected with the flue (1) through the thermotube (5), and the metallic expanding sub (7) is connected with the flue (1). During the operation of varying loads, the utility model has lustral effect. Once scale formation occurs, the cycling loop can not be blocked and is easy to rinse. The structure is more simple and compact by adopting an integrated structure and arranging the flue horizontally. The complete set of device adopts the metallic expanding sub to connect with the diesel engine flexibly, has no heat or additional effect upon the diesel engine, and simplifies the installation process by fixing and supporting independently.
Description
The utility model is a kind of drilling diesel engine heat pipe heat recovery boiler that utilizes oil drilling diesel engine high-temperature flue gas to produce steam.
At present, in the process of drilling well production in winter, owing to the requirement to steam, drilling crew all need be equipped with fire coal or oil burning boiler.Should be equipped with the professional increases human input, increases energy resource consumption again.And simultaneously drilling crew must be equipped with three or four diesel engines and carries out alternation and provide power for drilling well in ordinary production.And every diesel engine is when operate as normal, and 30%～40% energy is along with high-temperature flue gas, and as waste gas emitting in vain, flue-gas temperature causes very big waste up to 450 ℃.In some former diesel residual heat retracting devices, adopt modes such as boiler coil pipe, water quality heat pipe to carry out heat exchange, heat exchange efficiency is low, and result of use is not good, does not reach intended purposes, and uses inconvenience.
The purpose of this utility model is to provide that a kind of water-flow circuit is simple, the high drilling diesel engine of not tying ash, the not blocking heat pipe heat recovery boiler of heat transfer efficiency.
The utility model is achieved in that by flue 1, cylindrical shell 2, Pressure gauge 3, safety valve 4, heat pipe 5, limnimeter 6, expansion of metal pipe nipple 7, automaton device 8 to be formed, Pressure gauge 3 and safety valve 4 are housed on the cylindrical shell 2, there is limnimeter 6 cylindrical shell 2 ends, flue 1 adopts integrative-structure with cylindrical shell 2, cylindrical shell 2 is connected with flue 1 by heat pipe 5, and expansion of metal pipe nipple 7 is connected with flue 1.
The utility model also can be realized like this: flue 1 import and Way out are at an angle of 90.Flue 1 horizontal positioned.
On the heat pipe 5 in flue 1 fin is housed.
Pressure gauge 3 on the cylindrical shell 2 is electrically connected with the magnetic valve of automatic controller 8, and magnetic valve has the pipeline that connects cylindrical shell 2 inside.
Advantage of the present utility model is: owing to adopted inorganic heat pipe is heat transfer element, and inserting flue partly is the hot junction, absorbs heat, inserts the cold junction of shell portion by the inorganic heat transfer element conduction.Wherein, it is little that inorganic heat transfer element has thermal resistance, and the characteristics that equivalent heat conductivity is high have very high heat transfer efficiency so guaranteed waste heat boiler.In addition, conventional heat transmission equipment generally all is the partition heat exchange, and cold fluid and hot fluid flows through in the both sides of tube wall respectively, if tube wall leaks, will cause very big loss.And the waste heat boiler that adopts inorganic heat pipe is the heat exchange of secondary partition, cold fluid and hot fluid is respectively in the cold side and the hot effluent mistake of inorganic transport element, generally can not cold and hot side damage simultaneously, one side is damaged and is only lost a small amount of exchange capability of heat, the equipment that do not influence normally uses, and has strengthened the equipment reliability of operation greatly.Therefore, this waste heat boiler has safe and reliable characteristic.Have again, in this heat pipe waste heat boiler,, during the equipment variable load operation, have,, clean easily in case fouling can not stopped up closed circuit from the snaking effect because water is heat transfer free convection in the cylindrical shell large space.Because design the time has taken into full account rate of flow of fluid and relation from the deashing flow velocity, and the installation site of adjusting the flow direction of fluid and heat pipe to be reaching the purpose of deashing, and is provided with shoot door, is convenient to cleaning behind the knot ash.Adopt integrated design, and flue employing horizontal positioned, when increasing heat exchange area, make structure simpler, compact.Complete equipment adopts expansion of metal pipe nipple and diesel engine to flexibly connect, and diesel engine is not produced heat and added influence, and independent stationary, and independent support has been simplified installation process.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of flue 1.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model package unit level is installed in diesel engine top, is serially connected in the exit flue.Diesel engine is when normal operating conditions, and the high-temperature flue gas of discharge is by waste heat boiler flue 1, and through the vertical heat pipe that has fin 5 hot junctions of placing, and is delivered to cold section of the heat pipe of cylindrical shell 2 through inorganic heat transfer working medium, and the water in the cylindrical shell is heated to be water vapour.Wherein, fin is equipped with to increase heat exchange area in the hot junction of heat pipe in the flue.Cylindrical shell 2 is provided with safety valve 4, it is mouthful safe in utilization to guarantee waste heat boiler to diffuse, and transmit signal by limnimeter 6 and give automaton 8, when water level is in low level in the cylindrical shell 2, magnetic valve is opened, the pump work automatic water supplement, when high water level was arrived in moisturizing, pump quit work, closed electromagnetic valve is with the supply steam of guaranteeing that waste heat boiler can be continual and steady.
Flue 1 adopts horizontal positioned, and the import and export of flue become 90 ° of layouts, can make full use of the diesel smoke mouth, reduces energy loss.
Safety valve 2, Pressure gauge 3 are equipped with in horizontal cylinder 2 tops, and are provided with and diffuse mouthful, detect with hand hole and heating steam outlet, and a side is provided with limnimeter 6 interfaces, with hand control simplified in the water level vertical parallax, guarantee that boiler feedwater is reliable.Opposite side is equipped with sewage draining exit, is beneficial to incrustation scale and dirt.
Inorganic heat transfer heat pipe 5 adopts the product of Dalian entropy Li De company, heat pipe 5 fuses flue 1 and cylindrical shell 2, form an overall structure, wherein heat pipe 5 is arranged vertically, and the hot junction of an end band fin places flue 1, absorbs the energy in the high-temperature flue gas, make an end place in the cylindrical shell 2 as cold junction, by the inorganic working medium in the heat pipe 5, the useless flue gas heat of the diesel engine in the flue 1 is delivered in the cylindrical shell 2, water is heated becomes water vapour.
Expansion of metal pipe nipple 7 is used to connect the exhanst gas outlet of waste heat boiler flue air inlet and diesel engine, makes to form between waste heat boiler and the diesel engine to flexibly connect.
Automaton 8 comprises pump, magnetic valve and control circuit etc., and its main effect is that the steam of water level in the cylindrical shell and generation is controlled automatically, and cylindrical shell 2 is carried out giving automatically moisturizing.
