Abstract

The utility model relates to a smoke-eliminating dust-removing sulphur removal tank-plate type directional dust remover for a boiler. On the basis of the existing inversed fire-grate coal spreader, a front water-cooled wall is changed into a combustion-supporting long arch additionally arranged on the center line of a hearth from an open type hearth, and a directional dust remover is arranged in a horizontal flue arranged in the boiler. The utility model can prevent the inner part of the boiler from coking to affect combustion and make the combustion complete and sufficient, and combustible flyash returns the hearth again to be carried out with secondary combustion. The dust removing effect of the utility model can reach less than one level of the Ringelman blackness, the air content in standard meter is less than 228 grams /m 3, and the utility model can be widely used as the smoke-eliminating dust removing device for various industrial boilers.

Description

The directed deduster of boiler Synergistic and energy-saving smoke abatement and dust control sulphur removal frid formula

The utility model relates to a kind of equipment of smoke abatement and dust control sulphur removal.

The spreader feeder forward-moving grate chain-grate boiler that uses at present is the open type burner hearth, heating surface wear is serious, the flying dust amount is big, smoke dust discharge concentration is high, the loss of mechanical incomplete combustion value is excessive, and in order to address this problem, people have done multiple effort, as the boiler dust removal equipment of designing multiple version is used for smoke abatement and dust control, because technology is immature, the cleaner dust removing effects is undesirable at present, and boiler exhaust gas does not reach national standard.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of simple in structurely, cost is low, good dedusting effect, and efficiency of dust collection can reach lingemann blackness below 1 grade, and air mark Mi Hanliang is lower than 228 gram/m ³The directed deduster of boiler Synergistic and energy-saving smoke abatement and dust control sulphur removal frid formula.

Task of the present utility model realizes as follows: the directed deduster of boiler Synergistic and energy-saving smoke abatement and dust control sulphur removal frid formula, be on the basis of existing forward-moving grate spreader feeder, to change preceding water-cooling wall into set up combustion-supporting long arch by the open type burner hearth to the burner hearth center line, offer one to two row's louvre in donor after-flame section, be provided with pull bar between donor and the combustion-supporting long arch, combustion-supporting long arch fuses with preceding water-cooling wall arch tube, the directed deduster that is contained in horizontal flue in the stove is made of two parts up and down, top is that dust separating device is made of directed frid, the groove top is the directed sedimentation elbow of control of dust, its middle part is equiped with the anti-directed control of dust guide plate and the anti-directed dedusting inner guide plate that boils of boiling of 45 in sedimentation chute, by connecting arm-tie it is fused between the chute of the left and right sides, connecting arm-tie is fixed on the air-cooled fixedly square beam, fix an anti-closed guard that boils in the posterior end of chute, be fixed with the control of dust funnel below the closed guard, be fixed with heat insulation abrasionproof plate against the wind by support post on the control of dust funnel madial wall, the lower end of control of dust funnel is connected with dirt by flange and falls pipe, the outer setting of falling pipe at dirt has analog bracket, being positioned at dirt falls and the fly ash combustible material recover is installed below the pipe, be equipped with one on it, two, three grades of negative pressure pipes also have been provided with stove with preventing choke tube on the recover, a wind airduct header, the anti-plate down with the wind that boils, boiling protection stretches out pipeline section, secondary wind collection case and dust viewing-mirror.

The utility model is owing to changed water-cooling wall before original forward-moving grate spreader feeder into set up to the burner hearth center line combustion-supporting long arch by former open type thorax, and on its donor after-flame section, have uniform louvre, therefore promptly prolonged the interior stroke of stove of coal dust, solved the time of staying of coal dust in stove purpose greater than burning time, can realize preventing the purpose of coking influence burning in the stove again, realize burning cmpletely; Because be equiped with anti-directed control of dust guide plate and the anti-directed dedusting inner guide plate that boils of boiling in the chute of middle part, therefore the bounce unification that flue dust is incident in chute is combined into downward stress, is convenient to reclaim; Under dirt falls and manages simultaneously the fly ash combustible material recover is housed and makes flying dust return the burner hearth second-time burning again like this, realize smoke abatement and dust control.

Fig. 2 is combustion-supporting long arch view;

Fig. 3 is the A-A cutaway view of Fig. 2.

A most preferred embodiment of the present utility model, as figure, the directed deduster of boiler Synergistic and energy-saving smoke abatement and dust control sulphur removal frid formula is that the preceding water-cooling wall that will have the forward-moving grate spreader feeder now is changed into the combustion-supporting long arch of setting up to the burner hearth center line 27 by the open type burner hearth, offer one to two row's louvre in donor after-flame section, be provided with pull bar 25 between donor and the combustion-supporting long arch, combustion-supporting long arch fuses with preceding water-cooling wall arch tube 24, the directed deduster that is contained in horizontal flue in the stove is made of two parts up and down, top is dust separating device, constitute by the directed frid of heat-resistance stainless steel, the groove top is the directed sedimentation elbow 3 of control of dust, its middle part is equiped with the anti-directed control of dust guide plate 2 and the anti-directed dedusting inner guide plate 1 that boils of boiling of 45 in sedimentation chute 6, sedimentation chute 6 front and back are provided with, quantity is more than two rows, before and after by connecting arm-tie 4 it is fused between the chute, connecting arm-tie is fixed on the air-cooled fixedly square beam 5, fix an anti-closed guard 7 that boils in the lower end of chute 6, be fixed with control of dust funnel 10 below the closed guard, be fixed with heat insulation abrasionproof plate 8 against the wind by support post 9 on the control of dust funnel madial wall, the lower end of control of dust funnel is connected with dirt by flange 11 and falls pipe 13, the outer setting of falling pipe at dirt has analog bracket 12, being positioned at dirt falls and fly ash combustible material recover 20 is installed below the pipe, be equipped with one on it, two, three grades of negative pressure pipes 18,21,23, also be provided with stove on the recover with preventing choke tube 14, a wind airduct header 15, the anti-plate 16 down with the wind that boils, boiling protection stretches out pipeline section 17, secondary wind collection case 19 and dust viewing-mirror 22.
