Description

Technical Field

[0001] This utility model relates to a dust collector, and more particularly to a corrosion-resistant and heat-dissipating double-layer vacuum dust collector, belonging to the field of dust collector technology. Background Technology

[0002] In the field of industrial dust control, dust removal equipment needs to achieve the best treatment effect in the temperature range of around 200℃ for dust-containing and acidic flue gas generated in high-temperature production processes such as sintering ore and cement clinker. This temperature can prevent the equipment from being corroded by the condensation of acidic gases and prevent the filter bags from failing due to high-temperature oxidation. However, existing dust collectors generally adopt a single-layer shell or fixed heat insulation structure, which relies on the temperature regulation of the air inlet. They cannot actively control the heat dissipation of different areas of the shell, resulting in a gradient temperature difference in the inlet section, middle section and outlet section of the dust collector. The temperature is uneven in different areas of the shell, and acidic condensate is easily formed in the low-temperature section, causing the filter bags to stick and the inner wall of the shell to corrode.

[0003] Therefore, it is urgent to improve the anti-corrosion and heat dissipation dual-layer vacuum dust collector to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant and heat-dissipating double-layer vacuum dust collector. This invention sets up multiple independent vacuum chambers between the double-layer shells, which are separated by partitions to form independent temperature control zones. The PLC adjusts the vacuum level of each chamber according to the temperature monitoring signal. By segmenting the vacuum chambers, the heat dissipation efficiency of each section is actively adjusted, thereby adjusting the heat dissipation effect of each section of the shell, thus affecting the internal temperature and keeping the temperature inside the shell within the optimal processing range of about 200℃, avoiding local overheating or overcooling.

[0005] To achieve the above objectives, the main technical solution adopted by this utility model includes: a shell and a cloth bag. The shell adopts a double-layer structure, including an inner shell and an outer shell. Multiple vacuum chambers are fixedly installed between the inner shell and the outer shell. The inner sidewall of each vacuum chamber is fixedly connected to the inner shell, and the outer sidewall of each vacuum chamber is fixedly connected to the outer shell. An air inlet is provided at the lower part of the shell, and an air outlet is provided at the upper part of the shell. The cloth bag is fixed inside the shell, and a slag discharge port is provided at the bottom of the shell.

[0006] Preferably, the outer wall of the vacuum chamber has a vacuum port that penetrates the outer shell. The vacuum port is connected to a solenoid valve, and multiple solenoid valves are connected to a vacuum pump.

[0007] Preferably, each of the vacuum chambers is equipped with an air valve on its outer shell and a temperature monitor is provided on the inner wall of the inner shell of each vacuum chamber.

[0008] Preferably, adjacent vacuum chambers are separated by a partition, which is a glass fiber reinforced plastic board, and the inner and outer ends of the partition are respectively sealed and fixedly connected to the inner shell and the outer shell.

[0009] Preferably, the vacuum chambers are evenly distributed along the axial direction of the housing, dividing the housing into multiple independent temperature control zones.

[0010] Preferably, at least three sets of temperature monitors are evenly distributed on the inner sidewall of the inner shell corresponding to the vacuum cavity.

[0011] Preferably, the temperature monitor is electrically connected to a PLC, which is used to receive temperature signals and control the vacuum pump, solenoid valve, and gas valve.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. This utility model sets up multiple independent vacuum chambers between the double-layer shells, which are separated by partitions to form independent temperature control areas. The PLC adjusts the vacuum level of each chamber according to the temperature monitoring signal.

Detailed Implementation

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] like Figures 1-4 As shown, the corrosion-resistant and heat-dissipating double-layer vacuum dust collector provided in this embodiment includes a shell 1 and a filter bag 2. The shell 1 adopts a double-layer structure, consisting of an inner shell 101 and an outer shell 102. Multiple vacuum chambers 3 are fixedly installed between the inner shell 101 and the outer shell 102, evenly distributed along the axial direction of the shell 1. Adjacent vacuum chambers 3 are separated by partitions 12 made of glass fiber reinforced plastic plates. The inner and outer ends of the partitions 12 are sealed and fixedly connected to the inner shell 101 and the outer shell 102, respectively, thereby dividing the shell 1 into multiple independent temperature control zones. The inner sidewall of each vacuum chamber 3 is fixedly connected to the inner shell 101, and the outer sidewall is fixedly connected to the outer shell 102. The lower part of the shell 1 is provided with an air inlet 4, and the upper part is provided with an air outlet 5. The filter bag 2 is fixed inside the shell 1, and the bottom of the shell 1 is provided with a slag discharge port 6.

[0022] The vacuum chamber 3 has a vacuum port 7 on its outer wall. The vacuum port 7 passes through the outer shell 102 and is connected to a solenoid valve 8. Multiple solenoid valves 8 are connected to a vacuum pump 9. Each vacuum chamber 3 has a gas valve 10 installed on its corresponding outer shell 102. At least three sets of temperature monitors 11 are evenly distributed on the inner side wall of the corresponding inner shell 101. The temperature monitors 11 are electrically connected to a PLC 13. The PLC 13 is used to receive temperature signals and control the vacuum pump 9, the solenoid valves 8 and the gas valves 10.

[0023] Dust-laden gas enters through the lower air inlet 4 of the housing 1, is filtered by the filter bag 2, and is discharged through the upper air outlet 5. Dust is discharged through the bottom slag outlet 6. During use, the temperature monitor 11 in each independent temperature control area collects the temperature signal of the inner wall of the housing 101 in real time and transmits the signal to the PLC 13. When the temperature difference between different parts of the housing 1 is too large, the PLC 13 controls the solenoid valve 8 of the vacuum chamber 3 corresponding to the lower temperature area to open, and starts the vacuum pump 9 to perform a vacuuming operation on the vacuum chamber 3. Since the vacuum environment can reduce the heat conduction efficiency, thereby reducing the heat dissipation in this area, the PLC 13 controls the gas valve 10 of the vacuum chamber 3 corresponding to the higher temperature area to introduce a small amount of gas into the vacuum chamber 3, reduce the vacuum degree of the vacuum chamber 3, improve the heat conduction efficiency, and increase the heat dissipation in this area. By actively adjusting the heat dissipation efficiency of each section through segmented vacuuming, the temperature of different parts of the housing 1 is affected, so that the temperature of different parts of the housing 1 is maintained in the optimal processing range of about 200°C, avoiding local overheating or overcooling.
