Description

Technical Field

[0001] This application relates to dust collectors, and more particularly to a cartridge dust collector structure. Background Technology

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas it can handle, the resistance loss of gas passing through the collector, and its dust removal efficiency. At the same time, the price, operating and maintenance costs, service life, and ease of operation and management are also important factors to consider when evaluating its performance. Dust collectors are commonly used facilities in boilers and industrial production. After a period of operation, dust collectors require regular cleaning. Electromagnetic pulse valves are currently the only valves in technology that can generate pulsed gas; these pulse valves are used for dust removal in dust collectors. Utility Model Content

[0008] Preferably, in the above-described cartridge dust collector structure, a silencer box is provided on the outside of the pulse chamber, and the air manifold and the electromagnetic pulse valve are located inside the silencer box.

[0009] Preferably, in the above-mentioned cartridge dust collector structure, the silencer box includes an inner microporous aluminum plate, an outer aluminum protective plate, and sound-absorbing cotton formed between the inner microporous aluminum plate and the outer aluminum protective plate.

[0013] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 2 As shown Figure 1 The right view. Detailed Implementation

[0016] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Combination Figures 1-2 As shown, the cartridge dust collector structure 100 includes a dust collection chamber 101, a pulse chamber 102 formed on one side of the dust collection chamber 101, an air inlet 103 formed on one side of the dust collection chamber 101, and an air outlet 104 formed on one side of the pulse chamber 102. Multiple filter cartridges 105 are disposed inside the dust collection chamber 101. The inner cavity of each filter cartridge 105 is sealed to one end of a venturi tube 106. The venturi tube 106 extends sealed to the pulse chamber 102. An air reservoir 107 and an electromagnetic pulse valve 108 connecting the air reservoir 107 to the inside of the pulse chamber 102 are disposed outside the pulse chamber 102. A diffuser 109 is formed at the end of the electromagnetic pulse valve 108. The other end of each venturi tube 106 faces a diffuser 109. The diameter of the diffuser 109 gradually increases from the electromagnetic pulse valve 108 to the venturi tube 106.

[0018] In this embodiment, after a period of use, high-pressure gas is stored in an air tank and then released through an electromagnetic pulse valve. The pulse jet parameters are optimized as follows: the jet pressure is controlled at 0.4-0.6 MPa, the jet frequency is adjusted to 10-20 times / minute, and the jet time is set to 0.1-0.2 seconds. The diffuser outlet diameter is increased to 2.5 times the diameter of the jet pipe. This optimizes the airflow distribution and improves the dust removal efficiency. Specifically, the expansion of the gas disperses and removes the dust adhering to the filter cartridge surface.

[0019] Furthermore, a gap is formed between the Venturi tube 106 and the diffuser 109.

[0020] In this embodiment, the gas cannot be directly connected to the filter cartridge to prevent damage to the filter cartridge.

[0021] Furthermore, a silencer box 110 is provided on the outside of the pulse cavity 102, and the air bag 107 and the electromagnetic pulse valve 108 are located inside the silencer box 110. The silencer box 110 includes an inner microporous aluminum plate 111, an outer aluminum protective plate 112, and sound-absorbing cotton 113 formed between the inner microporous aluminum plate 111 and the outer aluminum protective plate 112.

[0022] In this embodiment, the inner layer is a microporous aluminum plate with a pore size of 0.5mm, and the outer layer is a 50mm thick eggshell sound-absorbing cotton + an outer aluminum protective plate, which improves the noise reduction effect and reduces the noise level from 100dB to 82dB.

[0023] Furthermore, a dust hopper 114 is provided below the dust collection chamber 101. A dust collection valve 115 and a dust collection trolley 116 are provided below the dust hopper 114.

[0024] In this embodiment, dust collection and timed dust removal are achieved.
