Problems solved by technology

[0004] The purpose of the present invention is to provide a flue gas waste heat recovery device to solve the problem that when the existing flue gas waste heat recovery device is used in the above-mentioned background technology, because the flue gas contains particles, waste residues and other impurities, the flue gas waste heat recovery device is absorbing The flue gas will inhale impurities such as particles and waste residues together. During the working process, the particles will accumulate, which will affect the use of the flue gas waste heat recovery device, and it is not convenient for the staff to clean up, thus affecting the flue gas waste heat recovery device. Service life, causing a certain degree of inconvenience to users

Abstract

The invention discloses a flue gas waste heat recovery device. The flue gas waste heat recovery device comprises a filter device and a cleaning device, wherein the filter device comprises an air inlet, movable grooves with integrated structures are formed in the two sides in the air inlet, connecting springs are fixed to the two sides in the movable grooves, a connecting ring plate is connected between the connecting springs, a vibrator is fixed to the bottom, relative to the inner sides of the connecting springs, of the connecting ring plate, and a ring groove is formed in the top, relative to the surface of the connecting ring plate, of the vibrator; through the filter device designed in a waste heat recovery device body, dust and particles can be conveniently blocked outside the waste heat recovery device, so that the situation that the use of the waste heat recovery device is affected due to the accumulation of the dust and particles in the waste heat recovery device is avoided; and through the cleaning device arranged at the bottom of the waste heat recovery device body, workers can conveniently clean the bottom surface of the waste heat recovery device body after work is finished, and the heat dissipation of the waste heat recovery device body is prevented from being influenced by the accumulation of dust.

Description

technical field [0001] The invention belongs to the technical field of flue gas waste heat recovery, and in particular relates to a flue gas waste heat recovery device. Background technique [0002] The high-temperature flue gas discharged from various metallurgical furnaces often takes away 20-50% of the heat supplied by the furnace. The flow direction of the flue gas from the metallurgical furnace is opposite to that of the preheated medium, and the waste heat of the flue gas can be fully utilized to achieve a higher preheating. Heat temperature, the wall needs to be made of heat-resistant materials, flue gas is the main way for general energy-consuming equipment to waste energy, flue gas waste heat recovery is mainly to convert the heat carried by the flue gas into usable heat through a certain heat exchange method , in order to further improve the thermal efficiency of the kiln and achieve the purpose of saving energy and reducing consumption, recycling flue gas waste he...
