Abstract
The utility model discloses a dust removal cloth bag pulse device, which comprises a main gas circuit and a bypass gas circuit, wherein the main gas circuit comprises a gas bag, a first cut-off valve connected behind the gas bag, an air-vent valve connected behind the first cut-off valve, a second cut-off valve connected behind the air-vent valve and a plurality of cylinders connected behind the second cut-off valve; the air inlet end of the bypass air path is connected between the air bag and the first cut-off valve, the air outlet end of the bypass air path is connected between the second cut-off valve and the air cylinder, and a quick-cut valve is arranged in the bypass air path. This dust removal sack pulse device is provided with the bypass gas circuit to set up two trip valves around the air-vent valve of main gas circuit, when the air-vent valve broke down, open the bypass gas circuit and cut off the air-vent valve gas circuit, can overhaul on line and change the air-vent valve, can not influence the pulse device work during the change, guarantee the normal use that the sack removed dust.
Description
Technical Field
The utility model relates to a sack dust collecting equipment, concretely relates to dust removal sack pulse device.
Background
The dust-containing gas in the blast furnace bag-type dust collector enters a filter chamber through a lower open flange, the thicker particles directly fall into a dust bin, the dust-containing gas is filtered by a filter bag, the dust is retained on the surface of the bag, and the purified gas is discharged into the atmosphere through a fan from a bag opening to a gas purifying chamber. When the dust on the surface of the filter bag continuously increases to a certain degree, the pulse device of the dust removal cloth bag is put into use, the program control instrument starts to work, the pulse valves are opened one by one, compressed air blows and cleans the dust of the filter bag through the nozzle, the dust attached to the surface of the cloth bag is quickly separated and falls into the dust bin, and the dust is removed through the dust discharge valve.
The pulse air source of the dust removal cloth bag is compressed air and passes through the air bag → the valve → the pipeline → the pressure regulating valve → each air cylinder, and the pressure regulating valve is most prone to failure and has high failure rate in the using process. The time for replacing the pressure regulating valve is more than 1 hour. And during replacement, the pulse stops working, so that influence is brought to dust collection.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the defects of the prior art, the utility model provides a dust removal sack pulse device, the device can realize on-line maintenance change air-vent valve.
The technical scheme is as follows: the utility model relates to a dust removal cloth bag pulse device, which comprises a main gas circuit and a bypass gas circuit, wherein the main gas circuit comprises a gas bag, a first cut-off valve connected behind the gas bag, an air-vent valve connected behind the first cut-off valve, a second cut-off valve connected behind the air-vent valve and a plurality of cylinders connected behind the second cut-off valve; the air inlet end of the bypass air path is connected between the air bag and the first cut-off valve, the air outlet end of the bypass air path is connected between the second cut-off valve and the air cylinder, and a quick-cut valve is arranged in the bypass air path.
Has the advantages that: compared with the prior art, the dust removal cloth bag pulse device is provided with the bypass air path, the two stop valves are arranged in front of and behind the pressure regulating valve of the main air path, when the pressure regulating valve breaks down, the bypass air path is opened, the air path of the pressure regulating valve is cut off, the pressure regulating valve can be overhauled and replaced on line, the work of the pulse device cannot be influenced during replacement, and the normal use of cloth bag dust removal is guaranteed.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the dust removal cloth bag pulse device comprises a main gas path and a bypass gas path.
The main gas path includes a gas bag 1, a first shut-off valve 2 connected to the rear of the gas bag 1, a pressure regulating valve 3 connected to the rear of the first shut-off valve 2, a second shut-off valve 4 connected to the rear of the pressure regulating valve 3, and a plurality of cylinders 5 connected to the rear of the second shut-off valve 4. The pipe diameter of the connecting pipeline of the main air passage is DN30, the pipelines on two sides of the pressure regulating valve 3 mainly adopt hard pipelines, and one side of the pipeline can be changed into hose connection according to the field situation so as to save space. The first cut-off valve 2 and the second cut-off valve 4 are both manual valves, and are manually opened and closed only under maintenance or other special working conditions, so that misoperation of the electric valves is avoided.
The inlet end of the bypass gas path is connected between the gas bag 1 and the first cut-off valve 2, the outlet end of the bypass gas path is connected between the second cut-off valve 4 and the cylinder 5, and the bypass gas path is internally provided with a quick-cut valve 6. When the pressure regulating valve 3 is overhauled, two cut-off valves at the front and the back of the pressure regulating valve can be closed, the air passage of the pressure regulating valve is cut off, and the quick cut-off valve 6 is opened to supply air through the bypass air passage like the air cylinder 5. The pipeline of the bypass air passage is also DN30 pipe diameter, which ensures enough flow pressure, and the quick-cutting valve 6 is also set as a manual valve and is manually opened only under special working conditions such as maintenance of the pressure regulating valve 3.
