The present invention relates to a deactivated SCR denitration catalyst purging device, an activation device and a regeneration system and corresponding methods, the activation device includes a regeneration main body tank, an ultrasonic atomization device, a catalyst rotating turntable and a micro negative pressure suction device; and the regeneration system includes the purging device, a cleaning device, a first drying device and the activation device which are connected in turn. The regeneration system can achieve deactivated catalyst regeneration, and compared with the normal regeneration process, the process is more thorough in purging and more complete in cleaning, also greatly improves the utilization ratio of a cleaning solution and a regeneration solution, and maximizes recovery of surface and pore structure of a deactivated catalyst.

The invention relates to an integral rotational radiation preheating mixing energy utilization device with flue gas chilling. The device comprises a gasification furnace body and a heat recovery unit, which are connected with each other through a flange; the heat recovery unit comprises a pressurized shell, a syngas inlet, a radiation heat exchange component, a flue gas chilling component, a convection heat transfer component, an attemperator component, a slag tank and a syngas outlet; the gasification furnace body is communicated with the heat recovery unit through the syngas inlet; syngas is subjected to radiation heat exchange and then chilling for temperature reduction, and then liquid slag falls into the slag tank for discharge; and the syngas reversely flows up, and is subjected to convection heat transfer for temperature reduction. The device integrates radiation heat exchange, flue gas chilling and convection heat transfer effectively, and can be used for an IGCC (Integrated Gasification Combined Cycle) power generation system, the sensible heat of crude syngas is absorbed to produce high-pressure steam or medium-pressure steam to generate power, the entire energy utilization rate is increased greatly, the energy recycling rate is high, the overall dimension of a waste-heat recovery boiler is reduced effectively, the manufacturing, transporting and installing are more convenient, and the problem of dust stratification on convection heat transfer surface can be eliminated.

The present invention discloses an air-type solar heat-collecting ventilation system. An extremely thin venting layer is formed between the solar radiation lighted side plate and the shaded side plate, and the thickness of the extremely thin venting layer is less than 15 mm, the length is ranged from several centre meters to several meters and the section inner flow rate is less than 5m / s, one end of the venting layer is air inlet and another end is air blowing mouth, the plate bodies of the end mouth surface formed by facing solar lighted side and shaded side are fully arranged and installedon the solar radiation lighted surface as air-type heat-collecting materials, the air blowing out mouth faces the collecting venting layer formed by the solar radiation lighted side and shaded side of plate bodies, at the same time the continuous space of plate bodies used for venting and connected with said air inlet is formed. The invention can provide adequate indoor ventilation to prevent chemical pollution, condensation and moldy and insects, on the other hand, the use of solar energy to release the cold venting air temperature in cold seasons, it plays an active role of preventing global greenhouse phenomenon and the problem of inadequate energy.

The invention belongs to the technical field of new energy equipment, and in particular relates to a new energy self-cleaning solar panel, including a solar panel, a brush plate is slidably connected to the upper side wall of the solar panel, and the left and right ends of the brush plate are fixedly connected with Sliding mechanism, the other end of the sliding mechanism is fixedly connected with a wing plate, the lower side of the solar panel is fixedly connected with a dust storage tank, and there are two dust scraping boards slidingly connected in the dust storage tank, and the opposite side walls of the two dust scraping boards Both are fixedly connected with connecting ropes, the other end of each connecting rope is fixedly connected with each sliding mechanism, a reset mechanism is arranged between the two scraping boards, and the four corners of the solar panels are fixedly connected with limiting blocks. The invention can make full use of the wind energy through the set wing plate, so that the brush plate slides up and down under the indirect drive of the wind, so as to remove dust from the surface of the solar panel and improve the absorption of light energy by the solar panel, and this process utilizes Clean and renewable wind energy, no need for external energy, clean and environmentally friendly.

The invention relates to a dust-cleaning mechanical air cooler, which is mainly used for cooling high-temperature flue gas in smelting and electric power industries, and belongs to the technical field of cooling equipment. It mainly includes heat dissipation pipes, wall panels, middle partitions, fans, ash hopper ring beams, ash hopper parts, and support platforms. superior. The invention has the advantages of simple structure, small volume, light weight, and low manufacturing cost; high-temperature flue gas goes out of the pipe, and cooling air goes inside the pipe, which facilitates dust removal, reduces wind resistance loss, and improves cooling efficiency; Ash, prolonging the service life.
