In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Show a kind of embodiment of cleaning vacuum plant of the present invention such as Fig. 1, comprise dust collection pipeline system 1, dust collection pipeline system 1 is provided with a plurality of quick Connection Blocks 2, the suction port of Connection Block 2 is provided with stifle 3 or is connected with suction nozzle 5 by attraction flexible pipe 4 fast, dust collection pipeline system 1 is connected with expansion chamber 6, expansion chamber 6 is connected with the first cyclone dust collectors 7 by conveyance conduit, be provided with charge level controller 29 in the first cyclone dust collectors 7, the first cyclone dust collectors 7 are connected with the second cyclone dust collectors 8 by conveyance conduit, the first cyclone dust collectors 7 and the second cyclone dust collectors 8 are connected with a screw conveyer 9 jointly, the second cyclone dust collectors 8 are connected with the first Roots vaccum pump 10 by conveyance conduit, conveyance conduit between the second cyclone dust collectors 8 and the first Roots vaccum pump 10 is provided with butterfly valve 11, conveyance conduit between butterfly valve 11 and the first Roots vaccum pump 10 is connected to safe transport pipe 25, safe transport pipe 25 is provided with antivoid valve 26 and load relief valve 27, the tail end of safe transport pipe 25 is provided with the second filter screen 28, the import and export of butterfly valve 11 is equipped with the first filter screen 12, on the conveyance conduit between butterfly valve 11 and the first Roots vaccum pump 10, be connected with water tank 14 by water pipe 13, water pipe 13 is provided with forced water supply valve 15, water tank 14 is provided with the first water-supply valve 30 and first row water valve 16, the first Roots vaccum pump 10 is connected with the second Roots vaccum pump 17 by conveyance conduit, the second Roots vaccum pump 17 is connected with water-bath 18 by conveyance conduit, be provided with limit switch 31 between the conveyance conduit between the second Roots vaccum pump 17 and the water-bath 18, be provided with check-valves 32 between conveyance conduit between the first Roots vaccum pump 10 and the second Roots vaccum pump 17 and the conveyance conduit between the second Roots vaccum pump 17 and the water-bath 18, the top of water-bath 18 is provided with the second water-supply valve 19, be provided with Silenced wet dust collector 20 in the water-bath 18, water-bath 18 times is connected with sewage water filtration pond 22 by drainpipe 21, be provided with second row water valve 23 in the drainpipe 21, be provided with spilling water pipeline 24 between water-bath 18 and the drainpipe 21.
Roots vaccum pump among the present invention is negative pressure relief valve, when cause because of a variety of causes negative pressure＞-during 70kPa, Roots vaccum pump oneself is shut down, in case Roots vaccum pump damages.Roots vaccum pump is provided with the other control box of machine, have Roots vaccum pump the keying button, duty shows and the functions such as long-range demonstration, resultant fault warning.
The deashing of the cyclone dust collectors among the present invention adopts air box impulse winding-up sub-room cleaning control mode.During the cyclone dust collectors normal operation, enter in the storage hopper that places the below in the cyclone dust collectors through the thick dust laden air that purifies of one-level cyclone dust collectors, big dust particle in the dusty gas drops in the storage hopper because of the Diffusion of gas stream Speed Reduction, and tiny dust enters in the sack cleaner in the cyclone dust collectors with air-flow, be delayed on the filter bag outer wall during filter bag in passing sack cleaner, cleaned gas is through the first filter screen, the carrier pipe deferent, two Roots vaccum pumps, the Silenced wet dust collector drains in the atmosphere, and the dust content of emission gases is lower than 30mg/Nm3.When filter bag outer wall dust layer progressive additive, the resistance of cyclone dust collectors increases thereupon, (rise to the required time of 1600Pa according to dust remover resistance by 1300Pa reaching the cleaning cycle of setting, the time that general cleaning cycle is set be 0.4-4 hour adjustable) namely enter the deashing operating mode, begin by the chamber pulse dust cleaning.When deashing begins, control by the PLC deashing, close the dish valve, then compressed air sprays in two filter bags in the Roots vaccum pump, the anti-filter bag of wearing carries out pulse jetting deashing, paste to pay dust (dirt cake) on the filter bag outer wall because of filter bag bulging, shake, break away from filter bag and fall in the storage hopper, after filtering, purifying, discharge.After deashing is complete, close butterfly valve by PLC control, so far, cyclone dust collectors full recovery normal operating conditions.The control system of cyclone dust collectors adopts the control of PLC microcomputer time-program(me), and the automatically controlled in required time program of PLC is sent instruction, the keying of control butterfly valve, the duty of realization cyclone dust collectors normal filtration and pulse dust cleaning.The control system of cyclone dust collectors also can realize the function of manual deashing.
Because air machinery is terminal in system, when the Roots vaccum pump running, whole system forms negative pressure, at this moment, inside and outside conveyance conduit, there is pressure reduction, air is inhaled into conveyance conduit, also brought into conveyance conduit by air with this while dust, state with Dual-Phrase Distribution of Gas olid flow to expansion chamber, in expansion chamber, and dust and air separation, the dust that is separated falls into the ash bucket of expansion chamber and stores, regularly draw off, the tail gas after the separation enters two cyclone dust collectors again and purifies, and the air after the purification enters atmosphere through two Roots vaccum pumps.
The exploitation vacuum device of giving a dinner of welcome, be exactly with vavuum pump as power, in pipeline, form negative pressure, dust at the mouth of pipe with air along Flows, after in separator, dust being collected, focus on, tail gas is discharging after purifying.Adopt the cleaning vacuum plant deashing, efficient is high, and without the dust secondary pollution, factory provides condition for creating civilization.It is large that the present invention can adapt to the metallurgical works Dust Capacity, and complicated component than the characteristics such as great, but also can be applicable to other field, as: power plant: the workshop coal dust everywhere that is scattered, the cleaning of slag etc. and the cleaning of coal yard etc.; Cement plant: each operation field the be scattered cleaning of material or the recovery of the cement that is scattered; Machine casting: the cleaning of various loose unpacked materials, dust, waste residue; The material recycle of other every profession and trades, cleaning.The principle that the present invention utilizes strength to carry as bearing medium, is transported to the local centralized collection of appointment, the device of processing with dust in the workshop with air (or other gases such as nitrogen etc.).High efficiency of the present invention is cleaned widely, has alleviated workman's work, uses safety, health, can not work the mischief to the healthy of workman.
