Description

Technical Field

[0001] The utility model relates to the technical field of chlorine dust removal, in particular to a chlorine dust remover unit. Background Art

[0002] The pulse bag dust collector is a new type of high-efficiency pulse bag dust collector improved on the basis of the bag dust collector. Since its advent in the 1950s, the pulse bag dust collector has been widely used at home and abroad and has been continuously improved. It has made great progress in purifying dust-containing gases. Due to the advanced cleaning technology and the greatly improved air-to-cloth ratio, it has the characteristics of large air volume, small footprint and reliable operation.

[0003] In the prior art, the treatment of chlorine dust and flue gas in the process of sponge titanium production requires the use of a pulse bag dust collector. However, in the existing circular single-unit pulse bag dust collector, when the pulse valve is in operation, the pressure relief port will discharge a small amount of gas into the atmosphere, and during maintenance, chlorine will remain inside the dust collector, which will cause poisoning to personnel and pose certain safety hazards. In order to solve the above problems, we propose a chlorine dust collector unit. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the utility model to solve the technical problems is: a chlorine dust collector unit, comprising a dust collector body; a stainless steel pulse valve, the outer side of the stainless steel pulse valve is fixedly connected to the outer side of the dust collector body; a pulse valve exhaust gas return pipeline, the pulse valve exhaust gas return pipeline is fixedly connected to the outer side of the stainless steel pulse valve; a top cover, the bottom of the top cover is fixedly connected to the top of the dust collector body; a compressed nitrogen pipeline, the outer side of the compressed nitrogen pipeline is fixedly connected to the outer side of the dust collector body, thereby avoiding chlorine gas from endangering the staff and reducing safety hazards during maintenance.

[0005] Preferably, all joints of the dust collector body are connected by PN1.0 flanges, and sealing gaskets are provided at the joints of the dust collector body. By providing pressure-resistant flange connections and sealing gaskets, leakage of toxic chlorine gas can be prevented when the dust collector is running, thereby preventing poisoning of personnel.

[0006] Preferably, the stainless steel pulse valve is made of 316L stainless steel, and the air vent of the stainless steel pulse valve is processed into a threaded connection form. By changing the original chlorine dust collector unit pulse valve into a stainless steel pulse valve, the large and small air vents of the pulse valve are connected to the pulse valve exhaust gas return pipeline through pneumatic components, and then discharged into the dust collector body through a flange connection, which solves the problem that the air vent will leak every time the pulse valve is sprayed, and prevents the compressed chlorine used for backblowing from being discharged into the workshop and causing poisoning of people.

[0007] Preferably, a transfer bin is provided at the bottom of the dust collector body, a unloading ball valve is fixedly installed at the connection between the transfer bin and the dust collector body, a pressure equalizing pipeline is fixedly connected to the top of the transfer bin, the top of the pressure equalizing pipeline is fixedly connected to the outside of the dust collector body, and the dust collector transfer bin is connected to the dust collector body by a pressure equalizing pipeline to ensure that the transfer bin is always operating at a slight negative pressure during the unloading process.

[0008] Preferably, an overflow valve and an air inlet valve are fixedly installed at the inlet of the dust collector body, an air outlet valve is fixedly installed at the outlet of the dust collector body, and an air storage bag is fixedly connected to the bottom of the air outlet valve. By switching the valves, it is ensured that the system can be maintained without stopping during maintenance, and the chlorine gas retained in the dust collector will not be discharged into the workshop, thereby increasing the safety of equipment maintenance.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model improves the airtightness of the dust collector body and increases the safety of equipment operation by changing all connections of the dust collector to pressure-resistant flange connections and adopting corrosion-resistant sealing gaskets for sealing.

[0011] 2. The utility model changes the original pulse valve of the chlorine dust collector unit into a stainless steel pulse valve. The large and small air leakage ports of the pulse valve are connected to the exhaust gas return pipeline of the pulse valve through pneumatic components, and chlorine is sent to the clean air chamber of the dust collector body, thereby avoiding leakage of compressed chlorine at the pulse valve and preventing chlorine from poisoning workers.

[0012] 3. The utility model provides a transfer bin, and the transfer bin is connected to the dust collector by a pressure-equalizing pipe, thereby ensuring that the dust collector body operates at a slight negative pressure and constant pressure.

[0013] 4. The utility model provides two dust collector bodies, one for use and one for backup, so that the system can be repaired without stopping the dust collector. In addition, by adding an air outlet valve, an air inlet valve, a relief valve and a compressed nitrogen pipeline, chlorine gas can be discharged during maintenance, thereby increasing the safety of equipment maintenance.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0019] Example:

[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: a chlorine dust collector unit, including a dust collector body 1; a stainless steel pulse valve 2, the outer side of the stainless steel pulse valve 2 is fixedly connected to the outer side of the dust collector body 1; a pulse valve exhaust gas return pipeline 3, the pulse valve exhaust gas return pipeline 3 is fixedly connected to the outer side of the stainless steel pulse valve 2; a top cover 4, the bottom of the top cover 4 is fixedly connected to the top of the dust collector body 1; a compressed nitrogen pipeline 8, the outer side of the compressed nitrogen pipeline 8 is fixedly connected to the outer side of the dust collector body 1. When in use, two sets of dust collector bodies 1 are installed in the chlorine fume treatment system, and one is used and the other is prepared, so that the system can be repaired without stopping. During maintenance, due to the continuous inflow of compressed nitrogen, the chlorine gas retained in the dust collector is discharged, which avoids the harm of chlorine gas to the staff and reduces the safety hazards during maintenance.

[0021] All connections of the dust collector body 1 are connected by PN1.0 flanges, and sealing gaskets are provided at the connections of the dust collector body 1. When in use, the airtightness of the dust collector is improved by changing all connections of the dust collector to pressure-resistant flange connections and sealing with corrosion-resistant sealing gaskets. By providing pressure-resistant flange connections and sealing gaskets, leakage of toxic gas chlorine can be prevented when the dust collector is in operation, which may cause poisoning of personnel.

[0022] The stainless steel pulse valve 2 is made of 316L stainless steel, and the air vent of the stainless steel pulse valve 2 is processed into a threaded connection form. When in use, the pressure relief port of the stainless steel pulse valve 2 adopts the pulse valve exhaust gas return pipe 3, and the compressed chlorine gas discharged from the pressure relief port is discharged into the clean air chamber of the dust collector body 1 through the pulse valve exhaust gas return pipe 3 to prevent chlorine gas leakage from the pulse valve air vent and cause personnel poisoning. By changing the original chlorine dust collector unit pulse valve to a stainless steel pulse valve 2, the large and small air vents of the pulse valve are connected to the pulse valve exhaust gas return pipe 3 through pneumatic components, and then discharged into the dust collector body 1 through flange connections, the problem of air leakage at the air vent every time the pulse valve is sprayed is solved, and the compressed chlorine gas used for backblowing is prevented from being discharged into the workshop to cause personnel poisoning.

[0023] A transfer bin 10 is provided at the bottom of the dust collector body 1, and a unloading ball valve 11 is fixedly installed at the connection between the transfer bin 10 and the dust collector body 1. A pressure equalizing pipe 9 is fixedly connected to the top of the transfer bin 10, and the top of the pressure equalizing pipe 9 is fixedly connected to the outside of the dust collector body 1. When in use, since the system is operating at a slight negative pressure, when the dust collector body 1 discharges materials into the transfer bin 10, the gas filled with materials in the transfer bin 10 flows into the dust collector body 1, which supplements the space vacated by the dust collector body 1 due to unloading, ensuring that the body operates at a slight negative pressure and constant pressure. The dust collector transfer bin 10 is connected to the dust collector body 1 by a pressure equalizing pipe 9, ensuring that the transfer bin 10 is always operating at a slight negative pressure during the unloading process.

[0024] An overflow valve 7 and an air inlet valve 5 are fixedly installed at the inlet of the dust collector body 1, and an air outlet valve 6 is fixedly installed at the outlet of the dust collector body 1. The bottom of the air outlet valve 6 is fixedly connected to a gas storage bag 12. During maintenance, the overflow valve 7 and the compressed nitrogen pipeline 8 on the upper part of the dust collector are opened, and the air inlet valve 5 and the air outlet valve 6 are closed. The compressed nitrogen enters the dust collector body 1, and the chlorine in the dust collector body 1 is discharged to a designated location through the pipeline behind the overflow valve 7, thereby avoiding the leakage of chlorine inside the dust collector into the workshop, causing poisoning of maintenance personnel in the workshop. By switching the valve, it is ensured that the system can be maintained without stopping during maintenance, and the chlorine remaining in the dust collector will not be discharged into the workshop, thereby increasing the safety of equipment maintenance.

[0025] Working principle:

[0026] When in use, the chlorine dust collector continues the working principle of the dust collector. The dust collector body 1 is provided with two sets, one for backup and one for use. When in use, close the top cover 4. When the stainless steel pulse valve 2 is in operation, the pressure relief port of the stainless steel pulse valve 2 adopts the pulse valve exhaust gas return pipe 3. The compressed chlorine gas flowing out of the pressure relief port of the stainless steel pulse valve 2 will flow into the pulse valve exhaust gas return pipe 3. The compressed chlorine gas is discharged into the clean air chamber of the dust collector body 1 along the pulse valve exhaust gas return pipe 3. The dust collector body 1 processes the chlorine gas.

[0027] During unloading, the material inside the dust collector body 1 is discharged downward into the transfer bin 10 through the unloading ball valve 11. Since the dust collector body 1 and the transfer bin 10 are connected by the pressure equalizing pipeline 9, the gas filled with the material in the transfer bin 10 flows into the dust collector body 1, which fills the space vacated by the unloading of the dust collector body 1, ensuring that the body operates at a slight negative pressure and constant pressure.

[0028] During maintenance, the overflow valve 7 and the compressed nitrogen pipeline 8 on the upper part of the dust collector are opened, the air inlet valve 5 and the air outlet valve 6 are closed, and compressed nitrogen is fed into the compressed nitrogen pipeline 8. The nitrogen drives the chlorine to flow to the overflow valve 7, and the chlorine is discharged to the designated location through the pipeline behind the overflow valve 7. At this time, the chlorine inside the dust collector body 1 is discharged without endangering the maintenance personnel, who can then perform maintenance on the chlorine dust collector.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
