Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to a waste heat power generation mechanism for flue gas from a garbage incinerator. Background Art

[0002] At present, people's treatment of domestic waste has gradually changed from the primary treatment methods of field dumping and simple landfill to advanced treatment methods such as composting fermentation, incineration power generation and resource recycling. In particular, due to the limited space available for garbage dumping and the increase in the cost of landfill, people pay more and more attention to the incineration and comprehensive utilization of garbage.

[0003] Waste heat refers to the sensible heat and latent heat that has not been reasonably utilized in the original design of energy-consuming devices in industrial enterprises that have been put into operation, including waste heat from high-temperature exhaust gas, waste heat from cooling media, waste heat from waste steam and waste water, waste heat from high-temperature products and slag, waste heat from chemical reactions, waste heat from combustible waste gas, waste liquid and waste materials, etc. The waste heat generated in waste incineration can be used for power generation.

[0004] However, the garbage flue gas contains a large amount of harmful impurities and waste dust. Directly using the flue gas waste heat to generate electricity will cause blockage and pollution inside the heat exchange tube. Most of the existing flue gas waste heat power generation devices lack filtering of the garbage flue gas when in use, thereby reducing work efficiency. At the same time, as the cooling water boils due to the increase in temperature and produces water vapor to be discharged, the cooling water in the heat exchange box will continue to decrease until it dries up, and it is difficult for existing power generation devices to replenish the cooling water in the heat exchange box in a timely manner.

[0005] Therefore, we propose a waste heat power generation mechanism for waste incinerator flue gas. Utility Model Content

The water pump runs to inject the cooling water in the water storage tank into the heat exchanger box until the laser emitter scans the laser reactor at the top and then the water pump is turned off to complete the operation of filling the heat exchanger box with cooling water.

[0011] Preferably, a connecting pipe is installed on the front end surface of the filter box, a filter plate is slidably installed inside the filter box, a dust box is fixedly connected to the bottom end surface of the filter box, a recovery box is slidably installed inside the dust box, an air supply pipe is installed on one side surface of the filter box, an air suction pump is installed on the other end surface of the air supply pipe, and the air suction pump is installed on one side surface of the heat exchange box; through the cooperation of the filter plate installed in the filter box and the dust collecting box at the bottom end, the filter plate can filter the garbage smoke, and the dust collecting box can collect the filtered waste dust, and the waste dust in the garbage smoke can be removed to avoid the inside of the heat exchange tube being contaminated by waste dust, thereby protecting the quality of the heat exchange tube.

[0012] Preferably, a control panel is installed on the back surface of the water tank, and the laser emitter scans to the laser reactor and is electrically controlled and connected by the control panel; the switch of the operable device is operated.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: through the cooperation of the heat exchange tube and the gas pipe installed inside the heat exchange box, when the flue gas in the filter box is filtered through the filter plate, the flue gas enters the heat exchange tube through the gas pipe, and since the water storage tank is filled with cooling water, the flue gas exchanges heat with the cooling water through the heat exchange tube until the residual heat in the flue gas is completely absorbed. At this time, the cooling water in the heat exchange box boils due to the increase in temperature, and the exhaust pipe installed on the top surface of the heat exchange box can discharge water vapor for power generation. Through the cooperation of the filter plate installed in the filter box and the dust collecting box at the bottom, the filter plate can filter the garbage flue gas, and the dust collecting box can collect the filtered waste dust, and the waste dust in the garbage flue gas can be removed to avoid the inside of the heat exchange tube being contaminated by waste dust, thereby protecting the quality of the heat exchange tube.
