Abstract
The gas recovery system of an air recycling pulverizing device comprises a tail gas recovery circuit, an air leak branch, a compressor and an exhaust duct, and is characterized in that the air leak branch is connected with the tail gas recovery circuit, the compressor inlet is connected with the outlet of the air leak branch, the compressor outlet is connected with the tail gas recovery circuit, and the exhaust duct is connected with the air leak branch. The invention gives a resolution to the environment pollution caused by micro powder or harmful gas contained in tail gas, and recovers powder to the utmost extent through utilizing recycling means, thus greatly reducing gas emission and decreases the economic losses caused by direct emission.
Description
(1) technical field
The present invention relates to a kind of circulated air grinding device, especially relate to gas recycling system of recirculation air pulverizer.
(2) background technology
Gas recycling system of recirculation air pulverizer is the vent gas treatment part of circulated air grinding device; the circulated air grinding device is to utilize the high speed winds that circulates in device inside; the material of having been clayed into power constantly is carried into material collecting device from milling equipment; being isolated high speed winds behind the powder by material collecting device is returned to grinding device through high pressure positive blower and is repeated said process; because the inflammable and explosive characteristic of powder has determined the whole circulation wind system will adopt special gas protection; and maintenance certain proportion special gas content; because whole circulation system is leaked out; the wind of the system of bleeding reduces the content of special gas in the circulated air; then must add highly purified special gas and guarantee special gas ratio circulated air from bypass; again because equipment component such as sack cleaner adopt extraneous Compressed Gas to carry out work; caused whole circulation wind air quantity to increase; must adopt the mode of tail gas to give off unnecessary gas; because discharge powder or pernicious gas that tail gas contains trace, environment polluted.At present, common solution is that tail gas is being handled, and reaches directly discharging after the environment protection emission index.Though its problem one is that the powder of contained trace or pernicious gas still pollute environment in the tail gas because above-mentioned tail gas reaches the environment protection emission index; Its problem two is to contain a large amount of special gases owing in the above-mentioned tail gas, and the cost of special gas is all very high, and directly discharging can cause bigger economic loss.The method of head it off all concentrates on and takes different exhaust treatment systems to reduce in the measures such as pollution now, though these methods can solve the problem that exhaust emissions brings to a certain extent, but the pollution and the special gas that but can't change environment discharge the economic loss of bringing, and have also increased equipment and investment simultaneously.
(3) summary of the invention
In order to solve the technical problem that above-mentioned prior art exists, the invention provides a kind of gas recycling system of recirculation air pulverizer of complete closed, this system has reduced the pollution of tail gas to environment greatly, has improved the utilization rate of special gas simultaneously again.
The technical scheme that adopts is:
Gas recycling system of recirculation air pulverizer, comprise the tail gas recycle loop, let out wind branch road, compressor, exhaust duct, the described wind branch road of letting out is connected with the tail gas recycle loop, the inlet of compressor is connected with the outlet of letting out the wind branch road, the outlet of compressor is connected with the tail gas recycle loop, exhaust duct with let out the wind branch road and be connected.
Operation principle: tail gas is introduced by the tail gas recycle loop and is let out the wind branch road, enter compressor by the tail gas of letting out after the wind branch road is handled, through compressor filter and the tail gas big arrival instructions for use of compression after handling after by the output of tail gas recycle loop, newly-increased unnecessary gas is discharged by the mode of letting out wind when letting out the wind branch road in the whole circulation.
The powder or the pernicious gas that the invention solves contained trace in the tail gas still pollute environment, utilize the mode of circulation that powder is reclaimed to greatest extent, and have reduced the discharge of gas greatly, have reduced because of directly discharging the economic loss that causes.
(4) description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
(5) specific embodiment
Please refer to Fig. 1, gas recycling system of recirculation air pulverizer of the present invention, comprise piece storehouse 1, grinding machine 2, pulsed jet cloth filter 3, powder storehouse 4, high pressure positive blower 5, let out wind device 6, let out wind branch road 7, compressor 8, tail gas recycle loop 9, piece storehouse 1 is connected with grinding machine 2 inlets, grinding machine 2 outlets are connected to pulsed jet cloth filter 3 by pipeline, the air outlet of pulsed jet cloth filter 3 is connected to the air intake vent of high pressure positive blower 5 by pipeline, the discharging opening of pulsed jet cloth filter 3 is connected to powder storehouse 4 by pipeline, the air outlet of high pressure positive blower 5 by pipeline with let out wind device 6 and be connected, the main air outlet of letting out wind device 6 is connected to the air inlet of grinding machine 2 by pipeline, let out wind device 6 bypass air outlets by tail gas recycle loop 9 with let out wind branch road 7 and link to each other, let out wind branch road 7 air outlets and link to each other with compressor 8 through tail gas recycle loop 9, compressor 8 air outlets pass through tail gas recycle loop 9 respectively with grinding machine 2 wind-supplying mouths, piece storehouse 1 wind-supplying mouth links to each other with pulsed jet cloth filter 3.Exhaust duct 10 with let out wind branch road 7 and be connected.Piece storehouse 1, grinding machine 2, pulsed jet cloth filter 3, powder storehouse 4, high pressure positive blower 5, to let out the system that wind device 6 formed be original system, the tail gas of discharging from the original system pipeline by tail gas recycle loop 9 with let out wind branch road 7 and be connected, be connected to compressor 8 through the tail gas of letting out after wind branch road 7 is handled, the tail gas pressure in compressor 8 exits raises, and is connected respectively to original system make-up gas place (grinding machine 2 wind-supplying mouths, piece storehouse 1 wind-supplying mouth and pulsed jet cloth filter 3) by tail gas recycle loop 9 after reaching the working pressure of original system.When letting out wind branch road 7, unnecessary gas process discharges by exhaust duct 10.Its characteristics are to satisfy the instructions for use of original system to gas after the original system discharge tail gas reclaims by tail gas recycle loop 9 after letting out wind branch road 7, compressor 8 processing, and send original system make-up gas place respectively back to by tail gas recycle loop 9 again, when letting out wind branch road 7, unnecessary gas process discharges by exhaust duct 10.
Claims (1)
1. gas recycling system of recirculation air pulverizer, comprise the tail gas recycle loop, let out wind branch road, compressor, exhaust duct, it is characterized in that the described wind branch road of letting out is connected with the tail gas recycle loop, the inlet of compressor is connected with the outlet of letting out the wind branch road, the outlet of compressor is connected with the tail gas recycle loop, exhaust duct with let out the wind branch road and be connected.
