More than 15cm is reached into cylindrical length；In order to environment-friendly, it is to avoid produce substantial amounts of nitrogen oxides, it is necessary to pacify in igniter
Low nitrogen burning system is filled, to ensure the control of the fuming-off temperature in coal-dust explosion container below 1200 DEG C；High temperature high voltage resistant is set
Container, be shaped as cylinder or other, goes out provided with piston, charging aperture, igniting, monitoring, discharge flue dust and ashes in cylinder body
Device needed for mouth etc..Pressure, temperature, coal dust cloud dust concentration, oxygen concentration sensor are drawn from coal-dust explosion container outer wall simultaneously,
To carry out coal-dust explosion on-line monitoring, automatic ignition, when into cylinder body moment spray into meet the coal dust cloud dirt of detonation condition when,
The more uniform aerial coal dust cloud dirt that suspends can be lighted a fire in time（850 DEG C, more than 4.5mJ）Cause detonation, produce it
Give birth to HTHP and promote piston to do work.In four stroke movements of piston, when in exhaust stroke, crank connecting link machine is utilized
Structure makes soot emissions mouthful opening, and piston moves to top dead centre from lower dead center, and the flue dust and tail gas after work by combustion in cylinder body is complete
Portion is discharged, and is extracted dump energy by processing system, is done work, moved in circles with this again.
To be generated electricity using coal dust acting as embodiment, the invention will be further elaborated below, and acting device is designed to
Cylinder block, piston is moved up and down inside it, is done work and generated electricity using the stroke operation principle of engine four.It may be designed to
Coal dust enters back into cylinder body work by combustion after being closed with air pre-mixing.
From volatile matter is higher and the relatively low raw coal of ash content moisture（Volatilization is divided into more than 25%, and ash content is below 15%）It is used as original
Material, is processed into the coal cinder that particle diameter is less than 20mm by disintegrating machine 1, then enters back into ball mill 2 and become the coal cinder less than 20mm
Particle diameter is less than 75 μm of coal dust, then by coal dust processing unit 3 to adjust coal powder density and air velocity and pressure, to incite somebody to action
Coal powder density is handled to 40g/m3Left and right, coal dust moisture is further reduced, reach coal-dust explosion using principle is dried
It is required that（Below moisture 8%）.The coal dust for meeting detonation condition is delivered into pre-mixing apparatus 5, while utilizing air distribution device 4（Can be right
The humidity temperature of natural air is handled, and reaches optimal explosion condition, air humidity≤10%, temperature >=20 DEG C）By fresh sky
Gas is delivered in pre-mixing apparatus 5, coal dust is thoroughly mixed to form coal dust cloud dirt with air, circle is delivered to by blowing device 6
The charging aperture 8 of post cylinder body 7 (coal dust detonation container), makes coal dust is more uniform to be suspended in cylinder block 7 (coal dust detonation container), when
Cylinder block 7（Coal dust detonation container）The Dust Concentration sensor 11 that outer wall is installed, oxygen concentration sensor 12, pressure sensor
13, related data is transmitted to central control system by the first temperature sensor 14, and pressure, oxygen concentration and coal dust cloud dirt are judged through system
When concentration, temperature, humidity meet coal dust detonation condition, starting ignition device 10 is aerial by more uniform suspension in time
Coal dust is lighted a fire（850 DEG C, more than 10mJ）Cause detonation, it is produced HTHP and promote piston acting 16.According to hair
The stroke operation principle of motivation four, piston 16 does first stroke, bottom dead center position is moved to from top dead centre, completes the mistake into fuel
Journey, following piston 16 does compression stroke, and top dead center position is moved to from lower dead center, and igniter 10 makes coal dust detonation promote work
Plug 16 does work, and acting promotes piston 16 to be moved to from top dead centre after bottom dead center position, and piston 16 completes the 4th stroke again, from
Lower dead center moves to top dead center position, and the flue dust and tail gas that are produced after coal dust detonation are discharged from soot emissions mouthful 9, pass through pipeline
Into flue dust and exhaust treatment system 18, also repeated after specially treated and utilize dump energy, finally enter recycling dress
Put 19 to be done work, further improve coal dust utilization rate.
