Description

Technical Field

[0001] The utility model relates to the technical field of combustion furnaces, in particular to an organic waste gas combustion furnace. Background Art

[0002] Some organic waste gas will be generated in the production process of magnetic materials. In order to avoid the harm of organic waste gas to human body, it is necessary to burn these organic waste gas. The combustion of organic waste gas refers to the thermal oxidation decomposition and combustion of waste gas under direct high temperature conditions. However, this treatment method requires a lot of heat and energy consumption. Generally, the waste gas treated in this way has a high calorific value, and the concentration of organic matter in the waste gas is high. Under high temperature conditions, it can maintain high temperature incineration by using its own low calorific value.

[0003] According to Chinese patent CN210861139U, an organic waste gas combustion furnace has the following features: organic waste gas enters the combustion furnace from the bottom of the combustion furnace, and a hair dryer blows air into the combustion furnace, so that the organic waste gas moves in a spiral shape in the vertical furnace body, thereby extending the combustion time of the organic waste gas in the vertical furnace body and improving the waste gas treatment rate; a high-temperature mesh structure is arranged near the top of the inner cavity of the vertical furnace body, and the high-temperature mesh structure can heat the unreacted organic waste gas to cause secondary combustion, thereby further improving the organic waste gas treatment rate; the high-temperature mesh structure is a multi-layer high-temperature mesh layer stacking structure, which increases the contact area between the organic waste gas and the high-temperature mesh structure; a gap is arranged between two adjacent high-temperature mesh layers, and this design ensures the permeability of the high-temperature mesh structure, so that the post-combustion gas can pass through the high-temperature mesh structure smoothly.

[0004] When the above-mentioned combustion furnace burns the organic waste gas, a heating water tank is not set inside the combustion furnace, resulting in the heat generated by the organic waste gas during combustion being wasted, and the heat in the organic waste gas cannot be recycled, resulting in a waste of energy and further leading to heat loss. Therefore, an organic waste gas combustion furnace is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an organic waste gas combustion furnace, which has the advantages that when the organic waste gas is burned, the heat inside the combustion furnace can be used to heat water, thereby achieving the purpose of saving resources. It solves the problem that when the existing organic waste gas combustion furnace is burning, the internal heat is not utilized, resulting in a waste of resources.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an organic waste gas combustion furnace, comprising a combustion furnace, an air intake pipe is fixedly connected to the interior of the combustion furnace, a flamethrower is fixedly connected to the right inner wall of the combustion furnace, a spiral plate is installed inside the combustion furnace, two heat insulation plates are fixedly connected to the interior of the combustion furnace, a heating water tank is fixedly connected to the top of the bottom heat insulation plate, a spiral guide pipe is fixedly connected to the top of the bottom heat insulation plate, a fixed plate is fixedly connected to the inner wall of the combustion furnace, a filter element is detachably connected to the interior of the fixed plate, a mounting plate is detachably connected to the interior of the combustion furnace, a catalyst carrier is fixedly connected to the left side of the mounting plate, and a removal assembly is arranged on the right side of the combustion furnace.

[0007] Furthermore, the removal assembly includes an electric push rod, which is fixedly connected to the outer surface of the combustion furnace. The movable end of the electric push rod is fixedly connected to a support plate. The right side of the mounting plate is fixedly connected to a connecting sleeve, and the connecting sleeve is detachably connected to the support plate by bolts.

[0008] Furthermore, a placement groove is provided on the right inner wall of the combustion furnace, and the mounting plate is located on the inner wall of the combustion furnace through the placement groove. A second sealing gasket is fixedly connected to a side of the mounting plate close to the combustion furnace.

[0009] Furthermore, the spiral plate is welded to the inner bottom wall of the combustion furnace, the bottom of the heat insulation plate is fixedly connected with a deflector, the front of the heating water tank is fixedly connected with a suction pipe, and the top of the heating water tank is fixedly connected with a water injection pipe.

[0010] Furthermore, a conical cover is fixedly connected to the top of the fixing plate, one end of the spiral guide tube away from the bottom insulation plate is fixedly connected to the mounting plate, a sealing plate is fixedly connected to the right side of the filter element, screws are passed through the interior of the sealing plate, and the sealing plate is detachably connected to the right side outer surface of the combustion furnace by screws, and a first sealing gasket is fixedly connected to the side of the sealing plate close to the combustion furnace.

[0011] Furthermore, a drain pipe is fixedly connected to the bottom of the combustion furnace.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The organic waste gas combustion furnace, when the organic waste gas enters the interior of the combustion furnace through the air intake pipe during combustion, the flamethrower is ignited. Due to the existence of the spiral plate, the organic waste gas will burn in a spiral manner and stay longer during combustion. The catalyst carrier will catalyze the organic waste gas during the combustion process. The heat generated after combustion enters the interior of the spiral guide pipe through the guide cover to heat the water in the heating water tank, ensuring that the heat can stay for a longer period of time when discharged. Due to the direct contact between the heating water tank and the bottom insulation board, the flame of the organic waste gas can reach the bottom of the bottom insulation board when burning, directly heating the heating water tank; the heat of the spiral guide pipe will enter the interior of the fixed plate when it is discharged, the filter element can filter harmful substances in the gas, and the screws of the filter element can be removed and replaced after a period of use, thereby increasing the service life of the device.

[0014] 2. For the organic waste gas combustion furnace, when the catalyst carrier is being replaced, the electric push rod can be started to drive the support plate to move to the right, and then the mounting plate connected to the sleeve is separated from the inside of the combustion furnace, and the catalyst carrier is moved out for replacement. Compared with the existing manual replacement method, this structure is safer when used and can avoid finger burns as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS
