Technical field
The utility model relates to the device that carries out the sand and dust Separation and Recovery in a kind of inner-walls of duct sandblast work progress.
Background technology
The derusting by sandblasting of oil field pipe inwall, the main spray material that adopts usually is common silica sand, the abrasive blast equipment of employing is open, can have serious pollution problem like this.The oil field adopts first grade subsides device (cyclone dust catcher) to improve operating environment mostly at present, but effect and not obvious.
Summary of the invention
In order to solve dust pollution and the unconspicuous problem of dust removing effects that exists in the oil field pipe inwall sandblast process; The utility model provides the sand and dust separate absorbent environmental protecting device that uses in a kind of inner-walls of duct sandblast construction, and coming into operation of this device can improve construction environment, guarantees that dust emission is up to standard; And can effectively reclaim the sandblast material; Also have the service efficiency height in addition, cost is low, the characteristics of safety and environmental protection.
In order to realize the foregoing invention purpose; The technical scheme that the application adopts is: the inner-walls of duct sandblast is with sand and dust separate absorbent environmental protecting device; Comprise sandblast disposal box, dust conveyer belt, twin-stage cyclone separator, cloth bag back pulse deduster, dust discharge tube, dust collection jar and air-introduced machine, the wall box of said sandblast disposal box is provided with opening, openend mounting flange bindiny mechanism; The bottom is provided with outlet valve; The top is connected through the inlet of the I level cyclone separator in pipeline and the twin-stage cyclone separator, the inlet of the top outlet conduit connection II level cyclone separator of I level cyclone separator, the inlet of the top outlet conduit connection cloth bag back pulse deduster of II level cyclone separator; The outlet of cloth bag back pulse deduster is connected with the inlet of dust discharge tube, and in the porch of dust discharge tube air-introduced machine is set; The outlet below, bottom of above-mentioned I level cyclone separator, II level cyclone separator and cloth bag back pulse deduster is provided with the dust transport tape, and the dust collection jar is placed in the transmission terminal below of dust conveyer belt.
In order further to separate the grit in the dust collection jar, this device also comprises a vibratory sieve.
The beneficial effect of the utility model: the sand and dust separating and reclaiming device is used in this inner-walls of duct sandblast; Under the acting in conjunction of sandblast disposal box, twin-stage cyclone separator, cloth bag back pulse deduster and dust conveyer belt; Having guaranteed that on the one hand construction carries out in airtight environment, the dust discharge amount after the separation is up to state standards, having solved the environmental issue that the sandblast of oil field pipe inwall brings greatly; Have again; Also realize the secondary separation of dust and particle, made effective grit recycling, further reached the purpose of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-sandblast disposal box, 2-dust conveyer belt, 3-I level cyclone separator, 4-II level cyclone separator, 5-pocket type back pulse deduster, 6-dust discharge tube, 7-dust collection jar.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1: the inner-walls of duct sandblast is with sand and dust separate absorbent environmental protecting device; Comprise sandblast disposal box 1, dust conveyer belt 2, twin-stage cyclone separator, cloth bag back pulse deduster 5, dust discharge tube 6, dust collection jar 7 and air-introduced machine; The wall box of said sandblast disposal box 1 is provided with opening; Openend mounting flange bindiny mechanism, the bottom is provided with outlet valve, and the top enters the mouth through the I level cyclone separator in pipeline and the twin-stage cyclone separator 3 and is connected; The top outlet conduit of I level cyclone separator 3 connects the inlet of II level cyclone separator 4; The top outlet conduit of II level cyclone separator 4 connects the inlet of cloth bag back pulse deduster 5, and the outlet of cloth bag back pulse deduster 5 is connected with the inlet of dust discharge tube 6, and in the porch of dust discharge tube air-introduced machine is set; The outlet below, bottom of above-mentioned I level cyclone separator 3, II level cyclone separator 4 and cloth bag back pulse deduster 4 is provided with dust transport tape 2, and dust collection jar 7 is placed in the transmission terminal below of dust conveyer belt 2.
In the oil field pipe inwall sandblast process; Grit that falls and broken dust enter into a specific piping; This pipeline is connected with the flange of sandblast disposal box sidewall, that is to say that the grit that falls and broken dust finally enter in the sandblast disposal box, is under airtight environment, to carry out because grit and dust enter into the process of sandblast disposal box; Do not cause the problem of dust pollution construction environment so can not cause dust to leak, guaranteed the environmental requirement of construction; In the sandblast disposal box; Grit and dust carry out initial gross separation under the gravitational settling effect; Dust gets into I level cyclone separator, II level cyclone separator and pocket type back pulse deduster successively under the effect of air-introduced machine, and in said apparatus, carries out the fine separation of dust, through after above-mentioned a series of separating treatment; The dust emission index is up to state standards, and satisfies environmental requirement; In addition; Larger particles grit through I level cyclone separator, II level cyclone separator and the bottom sedimentation of pocket type back pulse deduster after processing a period of time is disposed on the dust conveyer belt; Be transported in the dust collection jar through conveyer belt then; Gleanings in the dust collection jar further can leave through vibrosieve, and the grit that can continue to use is separated, thereby has reached the purpose of recycling.
In sum, the sand and dust separating and reclaiming device is used in this inner-walls of duct sandblast, has solved the environmental pollution that oil pipe blasting treatment open work exists; This dust pelletizing system efficiency of dust collection is more than 99.5%; The outlet dust emission satisfies the national environmental protection emission request, not only reduces cost, and has practiced thrift the energy; Also reduced energy consumption, safe and reliable.
