The dual-spray-pipe pulse combustion thermal aerosol sprayer comprises a carburetor and a pulse engine body. The pulse engine body comprises a combustion chamber and spray pipes, one ends of the spray pipes are communicated with the combustion chamber, the carburetor is connected to the combustion chamber, drug inlets are formed in the spray pipes, and the spray pipes are two in number and are communicated through a communication pipe.
Description
Technical field
The utility model relates to a kind of intermittent combustion thermal aerosol generator, relates in particular to Helmholtz type intermittent combustion engine, belongs to intermittent combustion heating power atomization technique field.
Background technology
The intermittent combustion thermal aerosol generator also can be regarded as the intermittent combustion engine, is mainly used in forestry pest control.Helmholtz type pulse-jet engine generally comprises carburetor and pulsed motor body; The pulsed motor body comprises combustion chamber, tapering transition pipe, jet pipe that is connected successively; The large end of tapering transition pipe communicates with the combustion chamber, and small end communicates with jet pipe.Carburetor comprises inlet plenum and trunnion, being provided with on the locular wall of inlet plenum can be to the breather cheek valve of one-way air inlet in the inlet plenum, air inlet pipe communicates with inlet plenum, and the oil nozzle that communicates with oil pipe is arranged on the trunnion, and the combustion chamber inlet duct that is connected with carburetor in the combustion chamber arranges spark plug.
Because Helmholtz type intermittent combustion engine is by the shake result of mutual coupling of burning and gas column sound, therefore the function steady operation of normally pulsing is started in intermittent combustion, necessarily requiring acoustic construction condition and heating condition to satisfy simultaneously could realize, its size to each parts especially combustion chamber, tapering transition pipe, jet pipe, shape etc. have strict requirement, and each component structural will mate mutually.At present, owing to also have many working mechanisms unclear for the intermittent combustion engine, therefore also there is not fully reliable theory to determine the structure of intermittent combustion engine.Therefore in order can so that pulsed motor hugging is worked, constantly to debug each parts; Even through repeatedly debugging, the pulse-combustion engine can have been worked, the pulse-combustion engine exists still that engine is difficult to be started, and work be difficult for continual and steady, i.e. the easy problem such as flame-out.
Summary of the invention
The purpose of present technique provides a kind of double venturi intermittent combustion thermal aerosol generator that starts easily, can work continually and steadily.
The described double venturi intermittent combustion of present technique thermal aerosol generator, comprise carburetor and pulsed motor body, the pulsed motor body comprises the jet pipe that combustion chamber and an end communicate with the combustion chamber, carburetor is connected on the combustion chamber, be provided with feeding opening on the jet pipe, described jet pipe has two, is connected by a connecting pipe between two jet pipes.
Above-mentioned double venturi intermittent combustion thermal aerosol generator, two jet pipes parallel, and are positioned at the same side of combustion chamber.Best, communicating pipe and jet pipe are perpendicular.
Above-mentioned double venturi intermittent combustion thermal aerosol generator, carburetor comprises inlet plenum and trunnion, being provided with on the locular wall of inlet plenum can be to the breather cheek valve of one-way air inlet in the inlet plenum, air inlet pipe communicates with inlet plenum, the oil nozzle that communicates with oil pipe is arranged on the trunnion, and the combustion chamber inlet duct that is connected with carburetor in the combustion chamber arranges spark plug.
The beneficial effect of present technique: present technique adopts the double venturi form, and two jet pipes directly communicate with the combustion chamber (having removed tapering transition pipe of the prior art), simultaneously, and by communicating pipe two jet pipes being connected.This structure is so that easier formation sound thermal coupling between two jet pipes excites vibration mutually, so that engine is convenient to starting, and can lasting stability work, be conducive to simultaneously agricultural chemicals heating power fuming effect.
Description of drawings
Fig. 1 is the structure chart of double venturi intermittent combustion thermal aerosol generator;
Embodiment
Double venturi intermittent combustion thermal aerosol generator referring to shown in Figure 1 comprises carburetor 1 and pulsed motor body, and the pulsed motor body comprises combustion chamber 2 and two jet pipes that parallel 3.One end of two jet pipes 3 communicates with the same side of combustion chamber 2, between two jet pipes by with vertical being connected communicating pipe 4 of jet pipe.Between communicating pipe and jet pipe spout, be respectively arranged with feeding opening 9 on two jet pipes.
Carburetor 1 comprises inlet plenum 11 and trunnion 12, be provided with on the locular wall of inlet plenum and can (belong to prior art to the breather cheek valve of one-way air inlet in the inlet plenum, not shown), air inlet pipe 5 communicates with inlet plenum 11, the oil nozzle 7 that communicates with oil pipe 6 is arranged on the trunnion, and the combustion chamber inlet duct 10 that is connected with carburetor in the combustion chamber arranges spark plug 8.
Pass through air inlet pipe by air pump (hand pump or electric pump) output high-pressure gas during starting, enter the trunnion of carburetor, since the trunnion place to pass through area less, and air velocity is higher, form vacuum, oil is sucked by oil nozzle from oil pipe, and mix with air and to form combustion mixture, enter the combustion chamber through combustion chamber inlet duct, combustion mixture in the air inlet pipe of plug ignition ignition combustion chamber, spark is stretched rapidly to the combustion chamber, moment forms strong burning, air pressure in the combustion chamber rises rapidly and is higher than atmospheric pressure, this moment, breather check valve was in closed condition under the internal pressure of combustion chamber effect, waste gas after the internal combustion of combustion chamber can only be discharged from two jet pipes, air pressure in the combustion chamber drops to outside atmosphere presses when consistent, air-flow continues to efflux to pipe under the effect of gaseous mass inertia, pressure in the combustion chamber continues to descend, this moment, breather check valve was opened, fresh air enters the trunnion of carburetor through breather check valve, is mixed into mutually the combustion chamber from oil nozzle sucking-off fuel oil and with fresh air.When double venturi intermittent combustion engine work, close spark plug, the combustion mixture that enters the combustion chamber is lighted again at the ember of a upper circulation or by the high temperature combustors wall, the process that moves in circles of the burning of a formation new round-expansion-exhaust-air inlet enters the steady-working state of intermittent combustion.
In the startup of double venturi intermittent combustion thermal aerosol generator and course of normal operation, at synchronization, the parameters such as the gas flow rate in two jet pipes, pressure, flow can not be identical, always have the inflow and outflow of gas in communicating pipe, be conducive to reinforcement sound thermal coupling between two jet pipes, mutually excite vibration, so that this double venturi intermittent combustion thermal aerosol generator starts easily work that can be continual and steady.
Utilize and enter the oil solvent agricultural chemicals that the thermal current in the double venturi will enter in the jet pipe from feeding opening respectively after the double venturi pulsed motor burning and carry out the heating power fuming, adopt the coupled version of double venturi to be conducive to strengthen the turbulence intensity of air-flow in the jet pipe, this is conducive to heating power fuming effect so that the oil solvent agricultural chemicals that enters in the jet pipe can obtain rapidly more kinetic energy.
