Description

A kind of smoke eliminator

The utility model relates to a kind of smoke eliminator that Industrial Stoves institute smoke discharging is purified.

Contain a large amount of dusts and SO2 in the Industrial Stoves discharged flue gas at present, in order to reach the effect of dedusting and desulfurization, most of kilns adopt the method for wet dedusting, the nonaqueous dust cleaner that is about to be installed in behind original boiler is replaced by hydrofilter, the shortcoming of doing like this is to make the very high nonaqueous dust cleaner of original efficiency of dust collection to be left unused, wasted equipment, dust removing effects also can not get guaranteeing simultaneously.Existing in addition wet dedusting is adopted aspect dehydration and stopped dewatering type repeatedly, and is big to the resistance of flue gas, costs and poor dehydration results.

The purpose of this utility model provides a kind of novel smoke eliminator, and this device can effectively purify contained dust and SO2 in the Industrial Stoves discharged flue gas, and has carried out significant improvement aspect dehydration.

In order to achieve the above object, the utility model smoke eliminator is by tank box, atomising device, dewater unit, outer water tank, the ashing pond, sedimentation and filtration ditch, water circulating pump, the atomizing water pipe, overflow pipe, the mortar mud chamber, the mortar valve, mortar valve connecting rod, dividing plate, support, water inlet pipe, air admission hole and steam vent are formed, there is air admission hole a sidewall top of tank box, there is steam vent another sidewall top on the other side, its special feature is that there is dividing plate the box house top, air admission hole and steam vent are separated, there is dewater unit the dividing plate lower end, dewater unit one end and dividing plate are tightly connected, the sidewall of the other end and steam vent below is tightly connected, there is the mortar mud chamber box house below, there is the mortar valve lower end of mortar mud chamber, be connected with mortar valve connecting rod on the mortar valve, at the casing top that air admission hole is arranged atomising device is installed, atomising device links to each other with casing atomizing water pipe outward, on the atomizing water pipe water circulating pump is arranged, the other end of atomizing water pipe communicates with sedimentation and filtration ditch, be connected with a water inlet pipe on the sedimentation and filtration ditch, lateral wall at casing also has an outer water tank to communicate with box house, the lateral wall that outer water tank is higher than mortar caisson body also has an outer water tank to communicate with box house, outer water tank is higher than the mortar mud chamber, and be lower than the lower end of dividing plate, its bottom is connected with overflow pipe, overflow pipe links to each other with an ashing pond, and the ashing pond links to each other with sedimentation and filtration ditch.

Dewater unit in the above-mentioned smoke eliminator is an alternate angle page or leaf plate structure.

Adopt the smoke eliminator of said structure, owing to be to be installed at original nonaqueous dust cleaner back, both can desulfurization, can carry out double purification to flue dust again, guaranteed the effect of dedusting and desulfurization, the interlaced angular leaf plate structure of dewater unit has reduced resistance, and dehydrating effect also relatively significantly.Original nonaqueous dust cleaner is kept simultaneously, has avoided the waste of equipment.

Below in conjunction with accompanying drawing the utility model is done a detailed explanation.

Fig. 1 is installed in schematic diagram in the system for the utility model.

Fig. 2 is a topology view of the present utility model.

The utility model smoke eliminator is made up of tank box 1, atomising device 2, dewater unit 3, outer water tank 4, ashing pond 5, sedimentation and filtration ditch 6, water circulating pump 7, atomizing water pipe 8, overflow pipe 9, mortar mud chamber 10, mortar valve 11, mortar valve connecting rod 12, dividing plate 13, support 14 and water inlet pipe 15.There is air admission hole 16 a sidewall top of tank box 1, and flue gas enters purifier thus; There is steam vent 17 another sidewall top on the other side, and flue gas after being purified drains into chimney thus.There is dividing plate 13 the box house top, and air admission hole 16 and steam vent 17 are separated, and there is a dewater unit 3 the dividing plate lower end, and this dewater unit one end and dividing plate are tightly connected, and the sidewall of the other end and steam vent 17 belows is tightly connected.The box house below is mortar mud chamber 10, and there is mortar valve 11 lower end of mortar mud chamber 10, is connected with mortar valve connecting rod 12 on the mortar valve 11.At the casing top that air admission hole is arranged atomising device 2 is installed, atomising device 2 links to each other with casing atomizing water pipe 8 outward, on the atomizing water pipe 8 water circulating pump 7 is arranged, and the other end of atomizing water pipe connects sedimentation and filtration ditch 6, and sedimentation and filtration ditch 6 links to each other with water inlet pipe 15.Lateral wall at casing also has an outer water tank 4 to communicate with box house, and outer water tank 4 is higher than mortar mud chamber 10, and is lower than the lower end of dividing plate 13, and its bottom is connected with overflow pipe 9, and overflow pipe 9 communicates with an ashing pond 5, and ashing pond 5 communicates with sedimentation and filtration ditch 6.Atomising device 2 can adopt pressure atomizer, and the structure of dewater unit 3 is an alternate angle page or leaf plate structure.

During work, at first through water inlet pipe 15 to sedimentation and filtration ditch 6 water fillings, and the water in the sedimentation and filtration ditch 6 transferred to alkalescence, pH value is preferably in more than 10.Open water circulating pump 7 this moment, water circulating pump 7 injects casing through atomizing water pipe 8 and atomising device 2 with the form of water smoke with the water in the sedimentation and filtration ditch 6.When flue gas after nonaqueous dust cleaner 18 dedustings, enter smoke eliminator through air-introduced machine 19 by air admission hole 16, this moment water smoke flue gas is washed, in the alkalescence in the water and flue gas in SO2, dust falls into the mortar mud chamber 10 of casing below with water smoke, and flue gas obtains desulfurization and final dusting.The flue gas of process dust-removal and desulfurizing drains into chimney by steam vent 17 after the dehydration of the alternate angle impeller on the dewater unit 3.Fall into the dust of mortar mud chamber 10,, sink to bottom, mortar mud chamber through precipitating after a while, when dust accretions arrives to a certain degree, can pull mortar valve connecting rod 12, open mortar valve 11, water in the mortar mud chamber 10 is discharged, again mortar is cleaned out casing.The effect of outer water tank 4 is the water levels in the control mortar mud chamber 10, avoid the too high dividing plate of blocking of water level, flue gas can't be discharged, the water that flows out through outer water tank 4 bottom overflow pipes 9 flow back into sedimentation and filtration ditch 6 by ashing pond 5 simultaneously, inject casing by water pump again, realized circulating filtration.
