Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and more particularly to an inertia-controlled, compartment-based, offline dust removal device. Background Technology

[0002] The compartmentalized offline dust collector is mainly used for dust control in industrial fields. It achieves high-efficiency dust removal through a compartmentalized, alternating cleaning process. The inertia-controlled compartmentalized offline dust collector features a compartmentalized isolation system, dividing the housing into at least four independent filtration compartments. Each compartment outlet is equipped with a pneumatic sealing structure (stroke cylinder, pneumatic butterfly valve, etc.). Each compartment has an explosion vent below the tube sheet, and the lower part connects to the inlet collection cone and a double-layer pneumatic unloading assembly. It also features a pulse cleaning mechanism, with nitrogen / argon gas connected to the cleaning air manifold via a regulating valve and controlled by a programmable pulse controller. When the compartments are offline, the pulse-jet cleaning device is activated, working in conjunction with the venturi tube to enhance cleaning efficiency. The inertia-controlled system... The integrated compartment offline dust collector features a safety interlock system. A PLC controller monitors the pressure, temperature, and oxygen concentration before and after the dust collector in real time. Under abnormal pressure conditions, the top pressure relief valve automatically activates to release pressure. In extreme cases, each cleaning chamber can independently perform pneumatic explosion relief. Simultaneously, temperature sensors on the dust collector housing and the inlet collection cone control the closure of the inlet and outlet butterfly valves. The inertia protection system allows the compartment offline dust collector to perform its own cleaning and maintenance. Cleaning operations are facilitated by closing the dust collector's inlet and outlet valves, opening the compartment valves, opening the top passivation liquid inlet, and opening the lower liquid level display valve.

[0003] However, the existing inertial protection system for compartmentalized offline dust collectors still has the following problems during use: The replacement and maintenance of internal components in existing inertia-controlled offline dust collectors require separating the top cover from the housing. Reassembling the top cover and housing necessitates aligning the flange connections of the top cover and housing, making the assembly process more cumbersome, inconvenient, and physically demanding for operators. Therefore, it is essential to utilize inertia-controlled offline dust collectors in the existing dust collection equipment technology field. Summary of the Invention

[0019] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an inertial protection system for a compartmentalized offline dust collector. (Refer to...) Figure 1 and Figure 4 as well as Figure 5 The inertia-controlled offline dust collector includes a housing 22, with a top cover 11 mounted on the top of the housing 22. A cover opening mechanism 40 is mounted on the housing 22, comprising a horizontal bar 4000 fixedly mounted to the housing 22. A vertical bar 4001 is fixedly mounted to one end of the horizontal bar 4000, located on one side of the housing 22 and the top cover 11. An extension bar 4002 is fixedly mounted to the top of the vertical bar 4001, positioned above the top cover 11.

One mounting block 4004 has a first fixing block 4005 fixedly mounted to one end, and a second fixing block 4006 fixedly mounted to one end of the other mounting block 4004. The first fixing block 4005 is located above the second fixing block 4006. A traction rod 4007 is symmetrically fixed between a fixed block 4005 and a second fixed block 4006. A movable block 4008 is movably mounted on the two traction rods 4007. A connecting rod 4010 is fixedly mounted at the bottom of the movable block 4008. The connecting rod 4010 movably passes through the second fixed block 4006, and the bottom of the connecting rod 4010 is fixedly mounted to the top cover 11. A rotating cavity 4009 is provided inside the movable block 4008. A threaded rod 4011 is threadedly mounted on the first fixed block 4005. A rotating rod 4012 is fixedly mounted at the bottom of the threaded rod 4011.

A handwheel 4014 is fixedly mounted at the top of the threaded rod 4011. The handwheel 4014 is located above the first fixed block 4005.

[0020] In this invention, both the housing 22 and the top cover 11 are provided with flanges, and each flange is provided with mounting holes. Turning the handwheel 4014 causes the threaded rod 4011 to rotate and move on the first fixed block 4005. The threaded rod 4011 drives the rotating disk 4013 on the rotating rod 4012 to rotate on the rotating cavity 4009, causing the movable block 4008 to move on the two traction rods 4007. The movable block 4008 drives the top cover 11 on the connecting rod 4010 to move longitudinally, so that the flange mounting holes on the housing 22 and the flange mounting holes on the top cover 11 are aligned, eliminating the need for adjustment. This facilitates later assembly and fixation with bolts and nuts, improving operational efficiency.

[0021] Reference Figures 1-3 An oxygen content analyzer 12 is fixedly mounted on the housing 22. A temperature transmitter 21 is fixedly mounted on the housing 22. An air tank 20 is fixedly mounted on the housing 22. Multiple pulse valves 13 are fixedly mounted on the air tank 20. Each pulse valve 13 is fixedly mounted with a blowpipe 51, which extends into the interior of the housing 22. Each blowpipe 51 is fixedly mounted with a compartment isolation valve 43. An explosion vent 52 is fixedly mounted on the housing 22. An exhaust pneumatic butterfly valve 42 is fixedly mounted on the explosion vent 52. An outlet pressure transmitter 50 is fixedly mounted on the explosion vent 52. The bottom of the housing 22 is fixedly equipped with... It is equipped with a lower cone 32, on which a liquid level display window 23 is fixedly mounted. An air inlet pressure transmitter 30 is fixedly mounted on the lower cone 32, and an air inlet pneumatic butterfly valve 31 is fixedly mounted on the air inlet pressure transmitter 30. A discharge pipe 33 is fixedly mounted at the bottom of the lower cone 32. A pressure reducing valve 10 is fixedly mounted on the top cover 11. A passivation liquid atomizer 41 is fixedly mounted on the top cover 11. The passivation liquid atomizer 41 penetrates the top cover 11 and is located above the blow pipe 51. A filter material 53 is fixedly mounted on the inner wall of the housing 22 and is located below the blow pipe 51.

[0022] Working principle: During normal system operation, the liquid level display window 23 and the manual ball valve of the passivation liquid atomizer 41 are closed. The PLC sends a signal to open the inlet pneumatic butterfly valve 31 and the exhaust pneumatic butterfly valve 42. One group of compartment isolation valves 43 is closed, while the others are open. The corresponding pulse valve 13 is also opened, and compressed air enters the blowpipe 51 from the air tank 20 to clean each filter media 53. After cleaning is complete, the corresponding compartment isolation valve 43 is opened, and another group of compartment isolation valves 43 is closed. This cycle repeats, and the discharge pipe 33 begins normal discharge. Furthermore, during system operation, the system's automatic control system performs the following controls: 1. The inlet pressure transmitter 30 and the outlet pressure transmitter 50 compare the pressure difference between the front and rear ends in real time through the PLC. When the pressure difference is greater than the set value, the PLC will alarm.

[0023] 2. If the internal pressure exceeds the upper limit pressure of the pressure reducing valve 10, the pressure reducing valve 10 will automatically open to release pressure.

[0024] 3. When the pressure detected by the outlet pressure transmitter 50 exceeds the set value, the PLC will alarm.

[0025] IV. When the oxygen content analyzer 12 detects that the oxygen content concentration exceeds the set value, the PLC will alarm.

[0026] 5. When the temperature transmitter 21 detects that the internal temperature exceeds the first set value, the PLC will alarm.

[0027] 6. When the explosion vent 52 ruptures, if the internal temperature detected by the temperature transmitter 21 exceeds the second set value, the inlet pneumatic butterfly valve 31 and the exhaust pneumatic butterfly valve 42 will close, and the PLC will sound an alarm. When the system equipment stops operating and vulnerable parts such as filter media 53 need to be repaired or replaced, the liquid level display window 23 and the manual ball valve of the passivation liquid atomizer 41 are opened, while the air intake pneumatic butterfly valve 31 and the exhaust pneumatic butterfly valve 42 are closed. After observing that the liquid level display window 23 reaches a high liquid level, the manual ball valve of the passivation liquid atomizer 41 is closed. Then, the top cover 11 is opened using the cover opening mechanism 40 for replacement.
