This utility model relates to a rapid cooling and deacidification device, providing a rapid cooling and deacidification device for flue gas from a municipal solid waste incinerator. The device includes a base, a control cabinet, a water tank, metering pumps, and a drain pipe. The control cabinet is located on one side of the base, housing a data processing unit and a control module. A water tank is installed on the top right side of the base, and two metering pumps are located on the top of the base near the water tank. The input ends of both metering pumps are connected to the inside of the water tank, and the output ends of both pumps are connected to the drain pipe. This utility model achieves staged treatment of the gas flow by using a main cooling tank and a secondary cooling tank in cooperation. The secondary cooling tank pre-cools the gas flow, regulating the temperature of the gas entering the main treatment area to a preset temperature. The main cooling tank then performs deep cooling of the gas flow, completing the deacidification cooling process. This reduces the impact of gas temperature fluctuations on the overall treatment effect and significantly reduces the workload of the main cooling tank, improving the stability and efficiency of the system.

This utility model discloses a device for surface descaling and descaling of a municipal solid waste incinerator. A handheld handle is fixed to the bottom of the outer casing. The laser emitter, scanning galvanometer, and focusing lens are all located within the inner cavity of the outer casing. A laser irradiation port is provided on the side wall of the outer casing. The laser emitter is connected to the main body via an optical fiber. The scanning galvanometer is located between the laser emitter and the focusing lens. Emitters are also positioned between the scanning galvanometer and the laser emitter, and between the laser irradiation port and the focusing lens. The handheld optical focusing device utilizes the high-temperature ablation effect of laser light to precisely target the descaling area of ​​the incinerator, achieving non-contact descaling. The handheld design allows for flexible operation to adapt to complex furnace structures, avoiding physical damage to the furnace chamber caused by traditional mechanical descaling. Simultaneously, it can quickly remove descaling and corrosive substances from the inner wall of the furnace chamber, superheater, and economizer, while improving the surface's descaling and corrosion resistance.

This invention relates to the field of incinerator construction and masonry technology, specifically a method for constructing the lining of a municipal solid waste incinerator. The method includes: planning the masonry path based on a three-dimensional digital model of the incinerator body to generate a digital scheme for lining construction. An improved wavefront propagation algorithm is employed, using geometric constraints of already constructed blocks and a minimum mortar joint threshold to control wavefront expansion, dynamically generating a masonry sequence that conforms to the curved surface of the incinerator body. Prefabricated refractory blocks with positioning markers are used, and laser tracking positioning is used to complete the registration of the digital scheme with the on-site space. During construction, three-dimensional point cloud data is collected in real time to construct a masonry deviation field. Deviation feedback is used to adjust wavefront parameters, correcting the coordinates and attitude of subsequent blocks, forming an adaptive closed-loop control. This method can improve the conformity of the lining surface and the uniformity of mortar joints, suppress deviation accumulation, and improve the construction accuracy and stability of multi-layer refractory block masonry.
