Description

Technical Field

[0002] MPT technology integrates LvRTO technology with catalytic technology. LvRTO technology is used to realize waste gas circulation heat exchange and temperature rise. The heat storage chamber is arranged in upper and lower sections. The lower section is used for waste gas catalytic denitration. The upper section ceramic body heats up the waste gas to heat and decompose CO, VOCs, N2O, CH4, odor, dioxins and other components, thereby realizing the coordinated purification of multiple pollutants in an integrated device. The excess high-temperature flue gas in the combustion chamber can enter the waste heat boiler through thermal bypass for waste heat utilization. The combustion chamber does not need additional heat supplement, thus saving fuel consumption for waste gas temperature rise. The flue gas after heat exchange and cooling in the heat storage chamber passes through the catalyst bed again, and the waste gas and the denitration reducing agent ammonia are evenly mixed, and denitration reaction is carried out under the action of the catalyst, thereby achieving NOx purification treatment.

[0003] In the prior art, exhaust gas is simultaneously introduced into the bottom of the heat storage chamber, and the exhaust gas and reducing agent are mixed and catalyzed in the lower section of the heat storage chamber.

[0056] A method for using an exhaust gas denitration reducing agent mixed catalytic device based on MPT technology is as follows:

[0057] First, the top of the tank body 1 is installed in the combustion chamber, and the exhaust gas enters from the exhaust gas inlet at the bottom of the tank body 1, and the exhaust gas enters the mixing flow channel 4 through the through hole 1101 on the disc 11. At the same time, the heat in the combustion chamber is transferred to the honeycomb ceramic body 10 and the tank body 1, providing heat for subsequent heating and decomposition.

[0058] The motor 601 in the driving mechanism 6 is started, driving the strip plate 602 to rotate, and the eccentrically arranged first driving rod 603 drives the driving bar 605 to slide up and down on the T-shaped slide rail 604 through the connecting plate 606. The teeth on both sides of the driving bar 605 mesh with the gear 608, thereby driving the transmission rod 609 to rotate, and then driving the flow block 5 in a mixing channel 4 to flip to the horizontal to block the flow.

[0059] When the baffle block 5 is turned to the horizontal position, the pressure rod 717 at the top of the fan-shaped portion 503 is squeezed by the top of the fan-shaped groove 401, and the pressure rod 717 pushes the movable block 712 and the rectangular plate 713 to move downward, and the second driving rod 715 on the rectangular plate 713 slides in the second strip hole 710, pulling the bending plate 709 to rotate. The bending plate 709 pulls the valve plate 703 through the pull rope 708, overcomes the elastic force of the first spring 705, opens the valve body 702, and allows the reducing agent to be sprayed from the inside of the transmission rod 609 through the injection pipe 701 and the valve body 702 from the nozzle 716 toward the bottom of the baffle block 5.

[0060] When the baffle block 5 is turned to the horizontal position, the arc-shaped baffle surface 502 blocks the airflow and guides the airflow to present a rotating flow, so that the exhaust gas and the reducing agent sprayed from the nozzle 716 are fully mixed, so as to fully catalyze the reaction.

[0061] The airflow generated when the reducing agent is injected drives the fan blade 902 in the transmission knocking assembly 9 to rotate, and the first bevel gear 903 at the center of the fan blade 902 drives the second bevel gear 904 to rotate, and the second bevel gear 904 drives the third bevel gear 907 to rotate through the transmission shaft 905, and the third bevel gear 907 engages with the fourth bevel gear 908 to rotate the rotating rod 909.

The drum vibration waves are transmitted toward the top of the baffle block 5 to stimulate the mixing activity of the exhaust gas and the reducing agent.

[0062] At the same time, the driving mechanism 6 drives the baffle block 5 in another mixing channel 4 to flip to a vertical position, and the mixed gas enters the honeycomb ceramic body 10 to be heated and decomposed.

[0063] The baffle blocks 5 in the two mixing channels 4 are alternately turned to the horizontal position to perform alternate baffle mixing and convey the mixed gas toward the honeycomb ceramic body 10 to perform uninterrupted heating and decomposition.

[0064] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
