Embodiment Construction
[0009] combined with figure 1 , attached figure 2 and attached image 3 The present invention is described below.
[0010] The present invention is made up of exhaust pipe assembly 1, silencing fire extinguishing pipe 2, silencing blade 3, water spray ring 4. The exhaust pipe assembly 1 is divided into a front exhaust pipe 1a and a rear exhaust pipe 1b; an annular sound-absorbing blade 3 and a water spray ring 4 are welded in the cavity of the sound-absorbing fire-extinguishing pipe 2, and the inner chamber of the sound-absorbing fire-extinguishing pipe 2 is divided into Front noise reduction chamber 2a, cooling chamber 2b and rear noise reduction chamber 2c, ring-shaped front sealing cover 5a and rear sealing cover 5b are installed at both ends of the silencer fire extinguishing pipe 2, and the lower part of the rear sealing cover 5b has drainage holes 7. The upper part is welded with the water inlet pipe 6 connected to the water spray ring 4; the front exhaust pipe 1a is...

The invention relates to an exhaust pipe of a drilling diesel engine, which is composed of an exhaust pipe assembly, a silencer fire extinguishing pipe, a silencer vane and a water spray ring. The total composition of the exhaust pipe is a front exhaust pipe and a rear exhaust pipe; the cavity of the silencer and fire extinguishing pipe is welded with ring-shaped silencer blades and water spray rings, and ring-shaped front and rear seal covers are installed at both ends. The lower part of the rear sealing cover has a drain hole, and the upper part is welded with a water inlet pipe connected to the water spray ring; the front exhaust pipe is inserted into the central through hole of the front sealing cover and the sound-absorbing blade, and the rear exhaust pipe is inserted into the In the through hole in the center of the rear sealing cover. The present invention utilizes the exhaust pipe assembly, the silencing fire extinguishing pipe, the silencing blades, and the water spray ring to divide the silencing fire extinguishing pipe into a front noise reduction chamber, a cooling chamber and a rear noise reduction chamber, so as to realize multi-stage high-temperature exhaust gas discharged from the exhaust pipe of a diesel engine. The purpose of secondary noise reduction and cooling and fire extinguishing meets the safety and environmental protection requirements of drilling construction.
Description
technical field [0001] The invention relates to an exhaust pipe of a drilling diesel engine, which belongs to the technical field of diesel engine equipment for oil drilling rigs. Background technique [0002] Oil drilling mechanical drilling rigs are generally equipped with three 190-type diesel engines as power machines to provide continuous power for drilling construction. During drilling construction, the exhaust gas and smoke from the diesel engine are discharged out of the body through the exhaust pipe. Due to the relatively loud noise of the diesel engine, it seriously affects the health and normal life of employees and local residents; at the same time, in the construction of natural gas exploration wells, with the increase of well depth, the drilling load becomes heavier and heavier, and the temperature of the diesel engine is high or the combustion is incomplete. Sparks are often ejected, and if the natural gas in the well overflows, a major fire accident will eas...
