Description

Technical Field

[0001] The utility model relates to the technical field of combustion devices, in particular to a heat storage type combustion device. Background Art

[0002] Printing and packaging, laminating, coating and painting, electronics, PVC, semiconductors and many other industries will generate a large amount of volatile organic waste gas during the production process. Usually, a regenerative zeolite concentrated combustion device is used to treat the waste gas.

[0003] After searching the publication (announcement) number: CN219140796U, a heat storage type zeolite concentrated combustion device is disclosed, including a heat storage box, a zeolite particle layer and a zeolite block layer are fixedly installed inside the heat storage box, the heat storage box is connected to an air intake pipe through an air intake port opened at the center of the top of the heat storage box, a burner is arranged at the bottom of one side of the heat storage box, and the top and one side of the burner are respectively connected to a combustion heat exchange outlet pipe and a combustion heat exchange inlet pipe. The heat storage type zeolite concentrated combustion device, by providing a second fan, an air intake pipe, a second exhaust pipe and a filter layer, can be circulated, purified and filtered when the exhaust gas after combustion enters the purification box. Through multiple purification treatments, the exhaust gas meets the emission standards, ensuring the quality of the workshop environment. At the same time, the design of the chip tray, the movable groove, the connecting block and the pull plate can facilitate the collection of the debris after combustion, so that the user can pull the chip tray out of the connecting pipe.

[0004] Although the above scheme can carry out circulation purification and filtration treatment when the exhaust gas after combustion enters the purification box, and through multiple purification treatments, the exhaust gas can meet the emission standards, but when the flue gas burns in the burner, more solid particles will be produced. If these solid particles are not cleaned, it will affect the full combustion of the flue gas. For this reason, we propose a heat storage zeolite concentrated combustion device. Utility Model Content

[0005] The main purpose of the utility model is to provide a heat storage combustion device, which solves the problem that more solid particles will be generated when the flue gas burns in the burner through the provided combustion unit and the cleaning unit. If these solid particles are not cleaned, it will affect the complete combustion of the flue gas.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The combustion unit comprises a material storage pipe installed on the inner wall of the main unit, and a burner installed on the side wall of the material storage pipe;

[0009] The cleaning unit includes a U-shaped seat installed on the side of the main unit, a threaded shaft movably arranged in the U-shaped seat, a cleaning member arranged on the threaded shaft, and a driving motor installed at the input end of the threaded shaft.

[0015] Preferably, the discharge unit includes a purification cylinder installed on the side wall of the heat storage tank, a discharge pipe opened at the top of the purification cylinder, and a circulation pipe connected between the purification cylinder and the discharge pipe.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, through the arranged combustion unit and cleaning unit, when organic waste gas enters the combustion chamber, the fuel in the storage pipe is ejected by the burner to ignite the organic waste gas, and most of the generated solid particles will fall onto the bottom wall of the combustion chamber under the action of gravity. At this time, the driving motor drives the threaded shaft to rotate. At this time, the moving member drives the cleaning soft brush to move along the threaded shaft through the connecting plate, so as to sweep the solid particles on the bottom wall of the combustion chamber and finally discharge them from the discharge groove, realizing the timely cleaning of the solid particles in the burner and ensuring the full combustion of the flue gas; when the organic waste gas is burned, the generated gas is input into the heat storage tank through the gas transmission pipe, and the burned waste gas passes through the zeolite particle layer and the zeolite block layer in sequence for adsorption, so as to realize the purification of the waste gas. Subsequently, the discharge pipe inputs the adsorbed waste gas into the purification cylinder for further purification and then discharges it through the discharge pipe. Description of the Drawings
