Description
Technical Field
[0001] This utility model relates to the technical field of gas regenerative oxidation devices, specifically a skid-mounted low-concentration gas flameless oxidation heating device. Background Technology
[0002] Gas regenerative oxidation is a method for treating low-concentration methane gas. Its basic principle is to utilize the high-temperature environment generated in the regenerator and oxidation chambers to release heat during the oxidation process. Part of this heat is used to maintain the high-temperature environment within the regenerator chamber, while another part is released. The remaining heat serves as a usable heat source, allowing for the production of hot water or steam from the regenerator chamber, or high-temperature hot air from the oxidation chamber.
[0003] Current gas regenerative oxidation devices can pre-filter low-concentration gas and air to avoid contaminating the regenerative and oxidation chambers, but the filters used for the gas need to be manually cleaned or replaced, which is inconvenient. Utility Model Content
[0004] The purpose of this invention is to provide a skid-mounted low-concentration gas flameless oxidation heating device to solve the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a skid-mounted low-concentration gas flameless oxidation heating device, comprising a carrier plate and a heat storage oxidation tank mounted on the carrier plate. An air inlet pipe is connected to the air inlet of the heat storage oxidation tank. A filter screen insertion slot is provided on the air inlet pipe, and a filter screen is inserted into the slot. A telescopic rod bracket fixed to the carrier plate is provided on one side of the air inlet pipe. An electric telescopic rod is installed on the top of the telescopic rod bracket. The telescopic end of the electric telescopic rod is fixedly connected to the side of the filter screen. A filter screen cleaning mechanism is provided on the other side of the air inlet pipe, and the filter screen can be pushed into the inner side of the filter screen cleaning mechanism by the electric telescopic rod.
[0006] Preferably, the filter screen cleaning mechanism comprises a recovery water tank, a water pump, a filter screen cleaning chamber, a PLC controller, a servo motor, and a flushing pipe. The filter screen cleaning chamber is fixed to the side of the air inlet pipe. A receiving groove adapted to the filter screen is located at the center of the filter screen cleaning chamber, and the bottom of the receiving groove is open. A flushing pipe insertion slot is provided on each of the two sides of the top of the filter screen cleaning chamber. The flushing pipe has an n-shaped structure, and the spray heads on the flushing pipe are arranged opposite each other. The two ends of the flushing pipe are respectively inserted into the two flushing pipe insertion slots. A lead screw is provided on one side of the top of the filter screen cleaning chamber, and the other side of the top of the filter screen cleaning chamber... A smooth rod is provided on the side. The flushing pipe is threadedly connected to the lead screw, and the flushing pipe is slidably connected to the smooth rod. The servo motor is fixed on the outer end face of the filter screen cleaning chamber, and the power output end of the servo motor is connected to the lead screw. The PLC controller is fixed on the outer end face of the filter screen cleaning chamber. The recycling water tank is located below the filter screen cleaning chamber. The water pump is installed on the outer end face of the recycling water tank. The water inlet of the water pump is connected to the recycling water tank, and the water outlet of the water pump is connected to the water inlet of the flushing pipe through a water supply pipe. A metal filter screen is installed on the inner side of the recycling water tank. The PLC controller is electrically connected to the water pump, servo motor, and electric telescopic rod.
[0007] Preferably, the filter plate consists of a mesh frame and metal filter screens. Two metal filter screens are provided and fixed to both sides of the mesh frame respectively. A gap is provided between the two metal filter screens. A drain trough is provided at the bottom of the mesh frame.
[0008] Preferably, the metal filter plate consists of a ramp plate and a horizontal plate, with two ramp plates connected to form an inverted V shape, and the bottom of the ramp plate connected to the horizontal plate.
[0009] Preferably, a drainage groove is provided on each of the two sides of the bottom of the filter screen cleaning chamber.
[0010] Preferably, a forklift adapter slot is provided on each side of the carrier plate, and rollers are installed on the bottom of the carrier plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are: when the filter screen plate of this utility model needs to be cleaned, the electric telescopic rod will push the filter screen plate into the inner side of the filter screen plate cleaning mechanism, and then the filter screen plate cleaning mechanism can clean the filter screen plate. After cleaning, the electric telescopic rod shortens so that the filter screen plate is reinserted into the filter screen plate insertion slot on the air intake pipe. When the filter screen cleaning mechanism is running, the water pump injects water from the recovery water tank into the flushing pipe. Then, two rows of spray nozzles on the flushing pipe flush the filter screen. During this process, the servo motor drives the lead screw to rotate, so that the flushing pipe can move back and forth along the lead screw, thereby increasing the flushing range of the flushing pipe and improving the flushing effect. The flushed wastewater enters the recovery water tank through the drain trough and is filtered through the metal filter screen for reuse. The filter plate has two metal filters, which helps to improve the filtration effect of air. The filter plate has a drain trough that matches the open receiving groove at the bottom. When rinsing the filter plate, the sewage can be quickly discharged from the drain trough. There is a sufficiently wide gap between the two metal filters, so that the dirt on the metal filters can be more easily washed off. The metal filter screen consists of an inclined ramp plate and a horizontal plate. The ramp plate prevents dirt from accumulating on it, which helps maintain the filtration effect for a long time. The horizontal plate is used to accumulate dirt, making it easy to clean later. Attached Figure Description
