A kind of known common purification method is to utilize pressure pulse to remove sediment.Pressure pulse purifies, and at first is the sedimental surface of carrying is under the very high pressure, and then is under the very low pressure that this pressure official post sediment expands, and removes from the surface.For the inside surface of process for purifying equipment, must make pressure pulse pass equipment and produce mobile pressure differential.
The typical method that produces pressure pulse is to discharge the gases at high pressure short pulse by a valve to impact.Utilize gas burst as the method that produces shock wave.People's such as Enoksson (hereinafter claiming Enoksson) United States Patent (USP) 4089702 discloses a kind of explosive mixed gas that ignites, to produce the method for shock wave.This shock wave can be used for removing particle, as sand dust on the object inside surface and squama dirt.Yet the method for Enoksson has several shortcomings.The method of Enoksson must seal the equipment outlet device that will purify, and charges into the internal cavities of equipment with damp.The shortcoming of this method is that the technological process of the equipment that is cleaned is stopped, and another shortcoming of this method is a requirement segmentation purification main equipment, therefore, requires to seal each section with the valve in the process equipment or other device, and charges into each section with damp.Another shortcoming of Enoksson is can not strict control blast.
The United States Patent (USP) (hereinafter claiming Koerner) of granting Koerner discloses a kind of sound wave engine, produces ultrasound wave by an explosive gas.Yet it is imperfect that this sound wave engine is used for process for purifying equipment, and the method for Koerner is to vibrate or shake the equipment that is cleaned by producing loud resonant frequency, and the vibration of equipment or shake the inside surface of particle slave unit is removed.Koerner says that also this resonant frequency is continuous sound wave basically.Yet the vibration purification method of Koerner is imperfect for purifying large-scale process equipment, and is unaccommodated in other words conj.or perhaps.Most of main equipments are fixedly mounting mode firmly, and this equipment that just makes is difficult to vibration.And the sound wave that utilizes Koerner method purification main equipment need produce fortissimo comes induced vibration.This continuous loud sound wave is very unhappy and/or dangerous to life and near live in the equipment of being cleaned people.Koerner also advises, before purifying beginning, must suspend or finish the technological process of the equipment that is cleaned.
Therefore, an object of the present invention is to provide a kind of cleaning equipment and method, overcomes the shortcoming of known pulse cleaning equipment.This cleaning equipment and method can be used in the process equipment, when this equipment carries out technological process, needn't often dismantle.
Another object of the present invention provides a kind of explosion gas to produce the equipment of shock wave, and process equipment is passed in this shock wave motion, and removes sediment and the particle that is bonded on the process equipment inside surface.
The 3rd purpose of the present invention provides a kind of can pilot-gas the blast to produce the equipment of shock wave.
