Description

Offline bag filter

technical field

The utility model relates to an industrial exhaust gas dedusting device, in particular to an off-line bag dust collector. the

Background technique

The function of the dust removal system is to collect and process the waste gas and dust generated in the main engine and other devices, and discharge the gas that meets the requirements of environmental protection. the

Usually, the main frame of the off-line bag filter is composed of the upper casing and the lower ash hopper, and an isolation grid is set between the ash hopper and the casing; the ash hopper is in the shape of an inverted cone, and the ash hopper A dust discharge device is installed at the bottom; the cavity inside the shell is divided into multiple independent dust collection spaces by partitions; each dust collection space is divided into upper and lower parts by a flower plate, that is, the clean air located above the flower plate room and the filter bag room located under the flower plate; a plurality of dust-removing cloth bags are installed in the filter bag room; the clean air room is connected with the air outlet pipe. The dusty dust enters the ash hopper and then enters the dust bag. After being filtered by the dust bag, the cleaner air is discharged from the clean air chamber. In the offline bag filter with the above structure, since the two ends of the dust bag are fixedly connected, the dust accumulated on the inner wall of the bag is not easy to fall, so it is easy to cause blockage and needs to be cleaned frequently, resulting in low dust removal efficiency. the

Utility model content

The purpose of this utility model is to provide an off-line bag dust collector which can overcome the defects in the prior art and can clean the dust accumulated on the dust bag during operation. the

In order to solve the above problems, an off-line bag filter of the present utility model includes an upper housing and a lower ash hopper; the ash hopper is an inverted cone, and an ash discharge device is installed at the bottom of the ash hopper; The cavity inside the body is divided into multiple independent dust collection spaces by partitions; each dust collection space is divided into upper and lower parts by a flower plate, namely the clean air chamber above the flower plate and the filter below the flower plate. Bag room; a plurality of dust-removing cloth bags are installed in the filter bag room; the clean air chamber is connected with the air outlet pipe, and the feature is that a poppet valve is arranged between the clean air chamber and the air outlet pipe, and the poppet valve is connected with the cylinder ; There is also a pulse valve in the clean air chamber, and the pulse valve is connected with the compressed air storage tank. the

The ash discharge device is a screw conveyor. the

The off-line bag filter adopts the structure of the utility model. When the dust-containing gas enters the ash hopper, it turns upwards and passes through the dust bag. The dust is collected on the outer surface of the bag, and the purified gas enters the upper part of the filter bag chamber The clean air chamber is collected to the air outlet pipe for discharge. The housing is divided into several independent dust collection spaces by partitions, and each space is equipped with a poppet valve. When cleaning dust, the poppet valve is closed to cut off the air flow through the dust collection space, and then the pulse valve is opened to spray high-pressure air into the dust bag to remove the dust collected on the outer surface of the dust bag. The off-line bag filter of the utility model can clean the dust on the dust bag in time when the machine is turned on, so as to avoid the blockage of the bag and improve the dust removal efficiency accordingly. the

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. the

As shown in Figures 1 and 2, the off-line bag filter of the present utility model includes a housing 1 located at the top and an ash bucket 2 located at the bottom; the ash bucket 2 is an inverted cone, and the bottom of the ash bucket 2 is equipped with The ash discharge device 3; the ash discharge device 3 is a screw conveyor. the

The cavity inside the housing 1 is divided into multiple independent dust collection spaces by partitions; each dust collection space is divided into upper and lower parts by the flower plate 101, namely the clean air chamber 102 above the flower plate 101 and the The filter bag chamber 103 below the flower plate 101; a plurality of dust-removing cloth bags 104 are installed in the filter bag chamber 103; the

When the dust-containing gas enters the ash hopper 2, it turns upwards and passes through the dust-removing bag 104. The dust is collected on the outer surface of the dust-removing bag 104, and the purified gas enters the clean air chamber 102 on the upper part of the filter bag chamber 103 and collects in the outlet. Air duct 108 discharges. the

A poppet valve 105 is arranged between the clean air chamber 102 and the air outlet pipe 108, and the poppet valve 105 is connected to the cylinder 106; a pulse valve 107 is also arranged in the clean air chamber 102, and the pulse valve 107 is connected to the compressed air storage A gas tank (not shown in the figure) is connected. the

Since the housing 1 is divided into several independent dust collection spaces by partitions, each space is equipped with a poppet valve 105 . When cleaning the dust, the poppet valve 105 is closed to cut off the air flow through the dust collection space, and then the pulse valve 107 is opened to spray high-pressure air into the dust bag 104 to remove the dust collected on the outer surface of the dust bag 104. the

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the protection scope of the present invention. the
