[0002] At present, in the process of industrial production, boilers are often needed to process raw materials. The boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] During the process of raw material processing in the boiler, flue gas needs to be discharged. In order to treat the flue gas, it is often necessary to filter the flue gas. The usual filtering method is to set a dust collector at the end of the flue and use the filter bag inside the dust collector to filter the flue gas.

[0004] However, the flue gas from the boiler's tail flue carries large particles, dust, and sand that directly enter the dust collector, causing great wear on the filter bags, resulting in the need to frequently replace the filter bags. Although separation can be achieved by setting up a filter net, the existing filter net needs to be frequently disassembled and cleaned, which is inconvenient. For this reason, we propose a separation device based on the boiler's tail flue and a method of using the same. Summary of the invention

[0015] In a second aspect, the present invention provides a method for using the separation device for a boiler tail flue as described above, the method comprising the following specific steps: Step 1: Exhaust the flue gas through the exhaust duct, and the flue gas moves along the connecting flue. Then, the filter assembly is used to filter the flue gas. Large particles of impurities fall into the ash storage tank along the connecting flue. The flue gas further moves into the cyclone. The large particles, dust and sand in the flue gas are separated by the cyclone. Then, the particles, dust and sand fall into the ash storage tank, thereby separating the particle impurities in the flue gas. Subsequently, the large particle impurities in the ash storage tank are moved to the boiler ash tank through the ash conveying pipeline, and the flue gas in the cyclone moves to the dust collector along the dust removal pipeline: Step 2: Move the handle assembly outward, use the triangular block and the V-shaped block to limit the position, the V-shaped block drives the docking block to move, thereby driving the slide bar to move along the inside of the fixed sleeve, and the slide bar drives the cross plate to move, so as to use the cleaning plate to clean the filter assembly: Step 3: Press the handle assembly inward until the triangular block is separated from the V-shaped block, then rotate the handle assembly 90 degrees until the triangular block is plugged into the U-shaped block, and then move the handle assembly further outward so that the U-shaped block drives the slider to slide along the groove, thereby driving the Z-shaped block to move. The Z-shaped block will squeeze the positive push roller, thereby driving the push sleeve to move until the card rod is separated from the card slot. At this time, the mounting frame can be removed: Step 4: Insert the mounting frame along the fixed frame, and then push the handle assembly so that the U-shaped block drives the Z-shaped block to reset, and the Z-shaped block squeezes the reverse push roller, thereby driving the push sleeve to reset, so that the clamping rod is engaged with the clamping slot, and at the same time, the rubber pad and the rubber protrusion cooperate to use the clamping rod to squeeze the inner wall of the clamping slot, thereby squeezing the sealing frame, and using the sealing plate to squeeze the sealing frame to achieve sealing.

[0016] Technical effects and advantages of the present invention: (1) The flue gas is discharged through the exhaust duct, and then the flue gas enters the connecting flue, and then the flue gas is filtered by the filtering mechanism to separate large particles of impurities. The large particles of impurities enter the ash storage tank from the connecting flue, so that the large particles of impurities are collected. The flue gas in the connecting flue is further moved to the inside of the cyclone, and the cyclone separates the large particles, dust and sand in the flue gas. The large particles, dust and sand fall into the ash storage tank, and then the large particles of impurities in the ash storage tank are transported to the inside of the ash collecting component. At the same time, the flue gas in the cyclone enters the inside of the dust removal component, so that the flue gas dust is processed; (2) The handle assembly drives the connecting column to move, and the connecting column drives the connecting block to move. The triangular block and the V-shaped block are connected to each other and limited. The connecting block drives the V-shaped block and its connecting block to move, and then drives the sliding rod to move, so that the cleaning assembly can clean the filter assembly. In the later stage, the handle assembly can also be used to drive the pushing assembly to move, so that the clamping assembly is no longer connected to the mounting frame and the fixed frame, thereby facilitating the disassembly of the filter mechanism. (3) The filter is cleaned by the cleaning plate. Since the push spring is in a compressed state, the cleaning plate is driven to fully contact the outer surface of the filter, thereby cleaning the filter better. At the same time, when the mounting frame is disassembled later, the limit nut can be removed to replace the push spring, thereby maintaining the good cleaning effect of the cleaning component on the filter component.
