Description
Technical field
The utility model belongs to petroleum propping agent production technical field, relates in particular to a kind of waste gas dedusting system for petroleum propping agent workshop.
Background technology
Petroleum propping agent is again petroleum fracturing propping agent.In the time of petroleum gas deep mining, high clossing pressure deposits of low permeability is after frac treatment, Oil gas-containing rock layer is split, the passage that oil gas forms from crack, collect, now need fluid to inject rock basic unit, to exceed the pressure of formation fracture intensity, make pit shaft generation crack, rock stratum around, form a passage with high laminar flow ability, open for the crack that keeps forming after pressure break, oil gas product can smooth and easy passing through.
At present, the waste gas that petroleum propping agent workshop produces is generally all discharged in atmosphere, has caused so huge atmosphere pollution, and this disagrees with the energy-saving and emission-reduction policy that country advocates, and therefore needs badly and is improved.
Utility model content
The utility model, in order to solve weak point of the prior art, provides a kind of waste gas dedusting system for petroleum propping agent workshop that can collect dust in waste gas.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: for the waste gas dedusting system of petroleum propping agent workshop, comprise exhaust pipe, described exhaust pipe is provided with row's dust collection, and the outlet of exhaust pipe is connected with upper-spraying type deduster; Described each dust collection includes the hopper that is located at exhaust pipe downside, hopper is up big and down small pyramidal structure, hopper open top and with exhaust pipe internal communication, flow direction taking waste gas along exhaust pipe is forward direction, toxic emission inside pipe wall bottom is provided with the baffle plate that is positioned at hopper front side, and the height of baffle plate is less than radius of a circle in exhaust pipe, and hopper lower end is provided with tremie pipe, tremie pipe is provided with baiting valve, and the lower end of tremie pipe is connected with dust bag.
Described upper-spraying type deduster comprises sedimentation basin and is located at the casing of sedimentation basin top, bottom half is uncovered, bottom half level is provided with sparge pipe, the outlet shutoff of sparge pipe, sparge pipe top is provided with row's hole for water spraying vertically, the import of sparge pipe is connected with the high-pressure hose extending in sedimentation basin, high-pressure hose is provided with suction pump, suction pump is driven by variable-frequency motor, the upper left sidepiece of casing is connected with the outlet of exhaust pipe, top, casing right side is provided with blast pipe, and casing top inner wall is by left-to-right interval and be arranged alternately platoon leader's deflection plate and short deflection plate.
Adopt technique scheme, the waste gas that petroleum propping agent workshop is discharged is outwards arranged by exhaust pipe, first stopping through baffle plate, heavier particle is fallen in hopper, in the time that the dust accumulation in hopper is more, open baiting valve, be discharged in dust bag and be recycled.Now in waste gas, also have some dust, waste gas is entered in casing by the left upper portion of casing, variable-frequency motor drives suction pump, the clear water that suction pump extracts sedimentation basin internal upper part upwards sprays by the hole for water spraying on sparge pipe, under the stopping of long deflection plate and short deflection plate, the flow velocity of waste gas slows down, air-flow fluctuates in casing more up and down, in waste gas, residual dust adheres to and gathers on water smoke, forming larger heavier particle falls in sedimentation basin, by the dedusting again of water spray, substantially clean air is discharged in atmosphere by blast pipe.Water circulation in sedimentation basin is used, and in the time that the water yield is less, just in sedimentation basin, is added into clear water, has so fully saved water consumption.The height of baffle plate is less than radius of a circle in exhaust pipe, the not too large like this flow velocity that affects waste gas.
The utility model is reasonable in design, simple in structure, the dust in waste gas is removed and recycled, protection of the environment, and energy-saving and emission-reduction, for enterprise has saved production cost, practical, easy to utilize.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the waste gas dedusting system for petroleum propping agent workshop of the present utility model, comprises exhaust pipe 1, and exhaust pipe 1 is provided with row's dust collection, and the outlet of exhaust pipe 1 is connected with upper-spraying type deduster.Each dust collection includes the hopper 6 that is located at exhaust pipe 1 downside, hopper 6 is up big and down small pyramidal structure, hopper 6 open tops and with exhaust pipe 1 internal communication, flow direction taking waste gas along exhaust pipe 1 is as forward direction, exhaust pipe 1 inwall bottom is provided with the baffle plate 7 that is positioned at hopper 6 front sides, and the height of baffle plate 7 is less than the interior radius of a circle of exhaust pipe 1, and hopper 6 lower ends are provided with tremie pipe 8, tremie pipe 8 is provided with baiting valve 9, and the lower end of tremie pipe 8 is connected with dust bag 10.
