Description
Technical field
The utility model relates to cleaning equipment, relates in particular to a kind of explosion-proof low-frequency sound wave deashing device that is used for imflammable gas equipment.
Background technology
Because sound wave ash cleaner is extensive use of equipment such as boiler, heat exchanger, make that the dust stratification of its equipment inwall and flue inner surface is effectively removed, thereby improved labor strength and maintenance condition greatly, and improved operating efficiency, prolonged the service life of equipment.But dust stratification for imflammable gas medium apparatus inwall; blower fan as present domestic pressurizing point use; the dust stratification of inwalls such as its fan blade and pipeline has had a strong impact on the safe operation of equipment; thereby have to often shut down; under the hazardous environment condition of toxic gas, adopt and manually clear up; can not effectively guarantee personal safety, increase labour intensity again, also greatly reduce the service life of equipment simultaneously.
Summary of the invention
For make inflammable and explosive working environment especially the dust stratification of coal gas medium apparatus and conveying pipeline inner wall under equipment running status, effectively removed, the utility model provides a kind of safe, reliable, significant explosion-proof low-frequency sound wave deashing device of ash-removal effect.
Summary of the invention
The purpose of this utility model is achieved in that this explosion-proof low-frequency sound wave deashing device, and it comprises acoustic waveguide tube, base and is installed in fire-proof motor and low-frequency sound generator on the base respectively, fire-proof motor is connected with low-frequency sound generator by shaft coupling, with be equiped with explosion-proof solenoid valve on the air inlet pipeline that low-frequency sound generator is connected, and be equiped with explosion-proof solenoid valve, ball valve and loudspeaker successively on the acoustic waveguide tube that low-frequency sound generator is connected.
Above-mentioned low-frequency sound generator comprises rotor chamber and air accumulator, air accumulator air inlet and gas outlet join with high-pressure air source air inlet pipeline and rotor chamber air inlet respectively, the rotor chamber armature spindle is connected with fire-proof motor by shaft joint, and rotor chamber gas outlet and acoustic waveguide tube join.
Above-mentioned high-pressure air source adopts nitrogen, but not as the qualification to utility model, promptly also can adopt other inert gas is source of the gas.
The technological progress that the utility model is obtained:
(1). owing to taked a whole set of explosion precaution, each device in promptly installing, the standard that parts have all reached explosive-proof grade ExellT4, mechanical driving part also has higher explosive-proof grade, thereby the dust stratification cleaning that has fundamentally solved fan blade and equipment inwall under imflammable gas such as gas fittings running status, labor strength and maintenance condition have been improved greatly, improved operating efficiency, reduced simultaneously owing under the hazardous environment condition of toxic gas, adopt the danger of manually carrying out deashing, guaranteed personal safety effectively.
(2). because the low frequency wave that the utility model sonic generator produces is longer, decay is slow, be suitable for the acoustic energy transmission, have transmission, characteristics that refracting power is strong, thereby can form balanced energy field in the working region, not only can stop or destroy the combination between dust particle effectively, the deposition of prevention dust stratification on equipment, thereby can effectively stop owing to the dynamically balanced destruction of dust stratification to the equipment of running up, prolonged the service life of equipment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1,1 installing one fire-proof motor 2 and a low-frequency sound generator on the base of this explosion-proof low-frequency sound wave deashing device, with installing one explosion-proof solenoid valve 12 on the high-pressure air source air inlet pipeline 13 that low-frequency sound generator air accumulator 8 is connected, and install explosion-proof solenoid valve 5, stainless steel ball valve 6 and loudspeaker 7 successively on the acoustic waveguide tube 4 that low-frequency sound generator rotor chamber 3 gas outlets are connected.Described low-frequency sound generator comprises rotor chamber 3 and air accumulator 8, air accumulator 8 air inlets and gas outlet connect high-pressure air source air inlet pipe 13 and rotor chamber 3 air inlets respectively, rotor chamber armature spindle 10 is connected with fire-proof motor 2 by shaft joint 11, for instant playback be convenient to control pressure in the air accumulator 8, air accumulator 8 external Pressure gauges 9.
During the utility model work, fire-proof motor 2 rotates with the speed more than 2850 rev/mins, the working media high pressure nitrogen is through air source inlet 14, air inlet pipeline 13 and magnetic valve 12 enter air accumulator 8, and under the pressure of 0.3～0.8MPa, enter in the 3 high speed rotor rotated of low-frequency sound generator internal rotor chamber, the energy that the mechanical energy and the high pressure nitrogen of motor rotation produced is converted into the sound wave energy that frequency is 136～186Hz, after this sound wave enters acoustic waveguide tube 4, the explosion-proof solenoid valve 5 that is installed on the acoustic waveguide tube 4 is opened, and makes sound wave enter the loudspeaker 7 that are installed in the working region by stainless steel ball relief valve 6.This moment, the low-frequency sound wave of 136～186Hz acted on the energy field that forms equilibrium in working region such as gas fittings or the gas piping, this sound wave active force makes the dust particle in imflammable gas such as the coal gas produce concussion, stop or destroy between the dust particle and the combining of dust particle and equipment room, and make it to be in suspended state, dust particle to combination can make its fracture, and be broken into fine particle, thereby reach the purpose of deashing.
Use and detect through the scene to show, after on the gas fittings the utility model being installed, equipment blower fan running 3 months continuously is still working properly, and it is dynamically balanced unusual equipment not occur; And uninstalled equipment will once be shut down deashing in maximum one month.Therefore the utility model both can guarantee personal safety effectively, can increase work efficiency again, also can prolong the service life of equipment simultaneously, especially at coal gas pressurized equipment etc. very high value and promotion prospect was arranged at the imflammable gas medium.
Important technological parameters of the present utility model is:
Frequency of sound wave 136～186Hz
Acoustic power level＞136dB
Bleed pressure 0.3～0.8MPa
