Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a high-safety waste gas treatment device. Background Technology

[0002] The working principle of a baghouse dust collector is to use bag filter elements made of woven fiber material to intercept solid particles in dust-laden gas. When dust-laden gas enters the baghouse dust collector, the dust is trapped in the filter bags, thus purifying the gas. As dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference across the filter material reaches a certain value, it is necessary to clean the dust in the filter bags in a timely manner to ensure the normal operation of the dust collector.

[0003] When cleaning existing baghouse dust collectors, it is necessary to stop the machine and remove the filter bags. During the bag removal process, a small amount of exhaust gas will overflow through the installation port of the filter bags, causing exhaust gas leakage. This will affect the working environment inside the exhaust gas treatment workshop, reduce the air quality inside the workshop, and affect the health of the staff. Utility Model Content

[0004] This disclosure relates to a high-safety waste gas treatment device to address the problem that existing baghouse dust collectors require shutdown and bag removal during cleaning. During bag removal, a small amount of waste gas may leak out through the bag's installation port, causing a waste gas leak that affects the working environment inside the waste gas treatment workshop, leading to a decrease in indoor air quality and impacting the health of workers.

[0005] In a first aspect, this disclosure provides a high-safety waste gas treatment device, specifically comprising: a purification chamber and a waste gas diversion chamber. The waste gas diversion chamber is fixedly connected to the right side of the purification chamber. An waste gas inlet pipe is fixedly connected to the top of the waste gas diversion chamber. An exhaust pipe is fixedly connected to the top of the waste gas diversion chamber. A guide cylinder is fixedly connected inside the waste gas diversion chamber. A blocking sleeve is slidably sleeved outside the guide cylinder. An automatic blocking plate is fixedly connected to the front end of the blocking sleeve. A spiral assembly port is provided on the left wall of the purification chamber. A bag installation cylinder is installed inside the spiral assembly port. A dust filter bag is installed inside the bag installation cylinder.

[0006] In at least some embodiments, the inner wall of the spiral assembly port is threaded, the right wall of the purification box is provided with a circular inner insertion port, and the left edge of the inner insertion port is connected to a cylindrical insertion port extension tube by welding.

[0007] In at least some embodiments, a blocking plate top spring is fixedly connected to the middle of the right surface of the automatic blocking plate, the right end of the blocking plate top spring is fixedly connected to the right wall of the exhaust gas diversion box, and four limiting top rods are fixedly connected to the left surface of the automatic blocking plate.

[0008] In at least some embodiments, a ventilation side opening is provided through the cylinder wall of the bag mounting cylinder, and a mounting cylinder thread is machined at the left end of the cylinder wall of the bag mounting cylinder, and the mounting cylinder thread is spirally connected to the spiral assembly port.

[0009] In at least some embodiments, the bag mounting cylinder is a cylindrical structure, with an inwardly bent inner flange at the right end of the bag mounting cylinder, and an outflow tightening bolt spirally connected to the inner flange.

[0010] In at least some embodiments, the dust filter bag has an opening at its right end, and the edge of the opening at the right end of the dust filter bag is located between the inner fold and the inner wall of the bag mounting cylinder. The edge of the opening of the dust filter bag is tightened and fixed by a tightening bolt.

[0011] In at least some embodiments, the left end of the limiting top rod is abutted against the right edge of the bag mounting tube, and the right end of the bag mounting tube is tightly inserted into the inside of the insertion extension tube.

[0012] This utility model provides a highly safe waste gas treatment device, which has the following beneficial effects:

[0013] The exhaust gas treatment device of this invention improves the installation structure of the dust collector bags. Multiple sets of dust collector bags are installed inside the device and fixed in place by multiple bag mounting cylinders. Under normal conditions, high-pressure exhaust gas is injected into the internal space of the exhaust gas distribution box through the exhaust gas inlet pipe. The exhaust gas enters the interior of the dust collector bags through the inner inlet and the inlet extension cylinder. During the process of passing through the dust collector bags, large dust particles in the exhaust gas are intercepted by the dust collector bags, and only clean air passes through the dust collector bags into the internal space of the purification chamber. The purified air is then discharged through the exhaust pipe. During the discharge process, when cleaning the filter bags, disconnect the valve on the exhaust gas inlet pipe, rotate the bag mounting cylinder, and disassemble and pull the bag mounting cylinder and filter bags from the spiral assembly port. During this process, the automatic blocking plate slides to the left under the pushing action of the blocking plate top spring, allowing the automatic blocking plate to insert into the insertion extension cylinder and seal the insertion extension cylinder. This prevents exhaust gas from leaking into the purification box through the disassembled inner insertion port and insertion extension cylinder, thus improving the safety of the filter bag cleaning process and reducing the risk of exhaust gas leakage.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 7 :

[0028] This utility model proposes a high-safety waste gas treatment device, comprising: a purification box 1 and a waste gas diversion box 2. The waste gas diversion box 2 is fixedly connected to the right side of the purification box 1. A waste gas inlet pipe 3 is fixedly connected to the top of the waste gas diversion box 2. An exhaust pipe 4 is fixedly connected to the top of the waste gas diversion box 2. A guide cylinder 201 is fixedly connected inside the waste gas diversion box 2. A blocking sleeve 501 is slidably sleeved on the outside of the guide cylinder 201. An automatic blocking plate 5 is fixedly connected to the front end of the blocking sleeve 501. A spiral assembly port 101 is opened on the left wall of the purification box 1. A bag installation cylinder 6 is installed inside the spiral assembly port 101. A dust filter bag 7 is installed inside the bag installation cylinder 6. A thread is opened on the inner wall of the spiral assembly port 101. An inner insertion port 102 with a circular structure is opened on the right wall of the purification box 1. The left edge of 02 is connected to a cylindrical insertion extension tube 103 by welding. A ventilation side opening 601 is opened through the cylinder wall of the bag mounting tube 6. The left end of the cylinder wall of the bag mounting tube 6 is machined with a mounting tube thread 604. The mounting tube thread 604 is spirally connected to the spiral assembly port 101. The left end of the limiting top rod 503 is in contact with the right edge of the bag mounting tube 6. The right end of the bag mounting tube 6 is tightly inserted into the insertion extension tube 103. Under normal conditions, the mounting tube thread 604 of the bag mounting tube 6 is spirally connected to the spiral assembly port 101, and the right end of the bag mounting tube 6 is inserted into the insertion extension tube 103, connecting the internal space of the exhaust gas diversion box 2, so that the high-pressure exhaust gas inside the exhaust gas diversion box 2 can enter the bag mounting tube 6 and pass through the bag mounting tube 6 for filtration.

[0029] In this embodiment, a blocking plate top spring 502 is fixedly connected to the middle of the right surface of the automatic blocking plate 5, and the right end of the blocking plate top spring 502 is fixedly connected to the right wall of the exhaust gas diversion box 2. Four limiting rods 503 are fixedly connected to the left surface of the automatic blocking plate 5. Under normal conditions, the automatic blocking plate 5, under the pushing action of the blocking plate top spring 502, makes the limiting rods 503 fit tightly against the right edge of the bag installation cylinder 6, which plays a limiting role on the bag installation cylinder 6, so that the exhaust gas inside the exhaust gas diversion box 2 can enter the dust filter bag 7.

[0030] In Example 2, based on Example 1, the bag mounting cylinder 6 is a cylindrical structure. The right end of the bag mounting cylinder 6 is bent inward to form an inner folded flange 602, and an outflow tightening bolt 603 is spirally connected to the inner folded flange 602. The right end of the dust filter bag 7 has an opening, and the edge of the opening at the right end of the dust filter bag 7 is located between the inner folded flange 602 and the inner wall of the bag mounting cylinder 6. The edge of the opening of the dust filter bag 7 is tightened and fixed by the tightening bolt 603. The dust filter bag 7 is installed inside the bag mounting cylinder 6, and the outer edge of the dust filter bag 7 is tightened by the bolt to fix its opening to the opening of the bag mounting cylinder 6. After the exhaust gas enters the dust filter bag 7, the air penetrates the dust filter bag 7 and is discharged into the purification box 1 through the ventilation side port 601. The dust filter bag 7 is installed by clamping with screws, which can improve the quickness of disassembly of the dust filter bag 7 and facilitate the cleaning and replacement of the dust filter bag 7.

[0031] The working principle of this embodiment is as follows: First, under normal conditions, high-pressure exhaust gas is injected into the internal space of the exhaust gas diversion box 2 through the exhaust gas inlet pipe 3. The high-pressure exhaust gas enters the dust filter bag 7 through the inner inlet 102 and the inlet extension tube 103. During the process of passing through the dust filter bag 7, the dust filter bag 7 intercepts the particles in the exhaust gas, allowing clean air to pass through the dust filter bag 7 and enter the internal space of the purification box 1. The purified air is then discharged through the exhaust pipe 4. After a certain period of use, when a large amount of dust accumulates inside the dust filter bag 7, causing a reduction in the purification effect, the dust filter bag 7 needs to be disassembled and cleaned. The valve of the exhaust gas inlet pipe 3 is shut off, and the bag mounting cylinder 6 is rotated to connect the bag mounting cylinder 6 with the dust filter bag. Bag 7 is removed and pulled out from the spiral assembly port 101. During this process, the automatic blocking plate 5 slides to the left under the pushing action of the blocking plate top spring 502 and inserts into the insertion extension tube 103 to seal it, thus preventing the exhaust gas from leaking into the purification box 1 through the removal of the inner insertion port 102 and the insertion extension tube 103 of the bag installation tube 6, and preventing the exhaust gas from leaking into the workshop and causing pollution to the workshop air. The tightening bolt 603 is removed, the dust filter bag 7 is taken off and cleaned. After cleaning, the dust filter bag 7 is reinstalled into the bag installation tube 6, and the bag installation tube 6 is reinstalled into the purification box 1 through the spiral assembly port 101. Thus, the cleaning work of the dust filter bag 7 is completed.
