Abstract

The utility model discloses a shaft kiln bag dust remover used in the dust moving and cleaning of kilns and is composed of a dust removing body, a filtering bag, a filtering chamber, an air inlet pipe, an air outlet pipe, etc. The air outlet pipe is arranged at the upper part of the dust removing body; a reverse air blowing pipe is arranged on top of the dust removing body; a dust hopper is connected to the bottom part of the dust removing body; a dust unloading port is arranged at the bottom part of the dust hopper; filtering bags are respectively arranged inside each filtering chamber; the air inlet pipe installed with a guiding plate is arranged at the lower part of the dust removing body; a cutting off valve and a lifting and switching valve are arranged on the reverse air blowing pipe. The device has large filtering area, simple structure, and significant energy saving effect.

Description

The shaft kiln sack cleaner

Technical field

The utility model relates to a kind of deduster, the shaft kiln sack cleaner that particularly a kind of kiln uses.

Background technology

At present, the rotary counter-blowing sack cleaner of domestic use is only applicable to the normal temperature dedusting, udst separation for high temperature flue gases such as kilns, the phenomenon of bag, coking, corrosion filter bag easily takes place to stick with paste, and it is low to have filter efficiency, not easy-to-clean ash, high-temperature flue gas can not desulfurization etc. defective.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of employing bottom air intake is provided, and intake stack adopts hierarchic structure, and the filter bag wearing and tearing are little, the shaft kiln sack cleaner that efficiency of dust collection is high.

The purpose of this utility model is achieved in that and comprises deduster body, filter bag, filter chamber, blast pipe, discharge pipe. exhaust duct is positioned at the deduster upper part of body, reverse-blow pipe is installed in the top of deduster body, deduster body bottom is connected with ash bucket, cinder-discharging port is arranged at the bottom of ash bucket, and filter bag is housed respectively in each filter chamber; It is characterized in that the blast pipe that deflector is housed is positioned at the bottom of deduster body; Stop valve is housed on the reverse-blow pipe and promotes transfer valve.

Described filter chamber is set to six.

Compared with prior art, the utlity model has following advantage:

1, reasonable in design, simple in structure, volume is little, convenient operating maintenance.

2, adopt the bottom air intake, intake stack adopts hierarchic structure, the filter bag little long service life of wearing and tearing.

3, adopt microcomputer control, can carry out temperature and detect automatically, regularly hinder deashing surely, parameter adjustment is convenient.

Dewfall not when 4, using can prevent to burn bag effectively, stick with paste the bag accident and take place.

5, filter area is big, obvious energy conservation.

The explanation of accompanying drawing drawing

Fig. 1 is the utility model structural representation.

Fig. 2, Fig. 3 are the utility model dynamic structure figure.

The specific embodiment

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model is that the resistive connection that vertical kiln uses reveals sack cleaner, by advance,

exhaust duct

4,9, filter chamber, filter bag 3, ash bucket 2 compositions such as grade.Concrete structure such as Fig. 1, Fig. 2, Fig. 3.Reverse-blow pipe 7 is installed in the top of deduster body 5, and exhaust duct 9 is positioned at top one side of deduster body 5.Be provided with six filter chambers in the deduster body 5, every indoor filter bag 3 that is equipped with respectively.The intake stack 4 that deflector is housed is positioned at the bottom of deduster body 5.Stop valve 10 is housed on the reverse-blow pipe 7 and promotes transfer valve 8.Deduster body 5 bottoms are connected with ash bucket 2, and unloading valve 1 and cinder-discharging port 12 are arranged at the bottom of ash bucket 2.

Operation principle of the present utility model:

Fig. 3 is that exhaust outlet is opened, and the blowback air port is closed, and stop valve is closed, filter bag expansion schematic diagram.As Fig. 3, dusty gas is assigned to each filter chamber in the effect of intake stack 4 by deflector, under the interception of deflector, crude particle dust directly falls into ash bucket 2 without filter bag 3, reduce the wearing and tearing of dust granules to filter bag 3, most of dusty gas is uniformly by the hole on the deduster body lower face plate, make dusty gas pour in filter bag 3, dust is trapped in the inner surface of filter bag 3, and air-flow is purified through filter bag 3, purified gas enters air-introduced machine by exhaust duct 9, enters in the atmosphere then.

After deduster operation a period of time, the dust layer that filter bag 3 inner surfaces adhere to thickens, when the deduster running resistance behind certain value, need filter bag 3 deashings.Deashing duty such as Fig. 2, move downward when promoting transfer valve 8, valve plate is opened blowback air port and stop valve 10 when air outlet is closed, because the air-flow that back blowing machine blasts is the contrary air-flow opposite with the filtered airflow direction, changed the inside and outside pressure reduction of filter bag 3, make filter bag 3 become the flat state that contracts, thereby peel off the dust layer that filter bag 3 inner surfaces adhere to by expanding.Promote transfer valve 8 and move upward, valve plate is closed blowback air port and stop valve 10 when air outlet is opened, and this moment, filter bag 3 was re-inflated, and deduster returns to the normal filtration state.

Claims

1, a kind of shaft kiln sack cleaner comprises the deduster body, and filter bag, filter chamber, intake stack, exhaust duct, exhaust duct are positioned at the deduster upper part of body; Reverse-blow pipe is installed in the top of deduster body, and deduster body bottom is connected with ash bucket, and cinder-discharging port is arranged at the bottom of ash bucket, and filter bag is housed respectively in each filter chamber; It is characterized in that the intake stack that deflector is housed is positioned at the bottom of deduster body; Stop valve is housed on the reverse-blow pipe and promotes transfer valve.

2, shaft kiln sack cleaner according to claim 1 is characterized in that, described filter chamber is set to six.
