The invention relates to an energy-saving catalytic bed system which comprises an air inlet cover, a furnace body, an air outlet cover and a heat exchanger; air inlet channels and air outlet channels are alternatively arranged between the inner coaming of the furnace body and the outer coaming of the furnace body; the inlet of each air inlet channel is arranged on an upper end plate, and the outlet of each air inlet channel is arranged between a lower end plate and the inner coaming of the furnace body; the inlet of each air outlet channel is arranged between the upper end plate and the inner coaming of the furnace body, and the outlet of each air outlet channel is arranged on the lower end plate; a heater is arranged in the furnace body which corresponds to the outlets of the air inlet channels; an air outlet deflection cover is arranged below the middle part of the lower end plate which corresponds to the outlet of the air outlet cover; the heat exchanger is provided with a catalytic exhaust inlet, a catalytic exhaust outlet, a catalytic gas inlet, a catalytic gas outlet, a desorption gas supply inlet and a desorption gas supply outlet. According to the energy-saving catalytic bed system, the heat efficiency of a catalytic bed is effectively improved, the heat loss is reduced, the heat recovery and utilization rate is improved, the burning efficiency and purification rate are improved, heat exchange is increased, the heat energy is utilized more reasonably, and the energy saving and emission reduction requirements are met.

The invention relates to a catalytic bed furnace core structure with a guide shield. The structure comprises an upper end plate, a lower end plate and a furnace core outer peripheral plate; the upper end plate and the lower end plate are respectively fixedly mounted on the upper end and the lower end of the furnace core outer peripheral plate; a furnace core inner peripheral plate is arranged in the furnace core outer peripheral plate; gas inlet paths and gas outlet paths are alternatively arranged between the furnace core inner peripheral plate and the furnace core outer peripheral plate; the inlet of each gas inlet path is arranged on the upper end plate; the outlet of each gas inlet path is arranged between the lower end plate and the furnace core inner peripheral plate; the inlet of each gas outlet path is arranged between the upper end plate and the furnace core inner peripheral plate; the outlet of each gas outlet path is arranged on the lower end plate; a guide shield with an inversed rectangular pyramid structure is arranged at the lower face of the middle of the upper end plate. The catalytic bed furnace core structure is simple in arrangement and scientific and reasonable in design, the heat efficiency of the furnace core structure can be effectively improved, the heat loss is reduced, the heat recovery utilization rate can be improved, the temperature in the furnace core structure is more uniform during burning, and the burning efficiency and the purifying rate are improved.

The present invention provides a surface type gas stripping micro power reflux apparatus for refluxing suspension and concentration active sludge. The surface type gas stripping micro power reflux apparatus comprises a gas inlet pipe, end head sealing mud suction pipes, a periphery closing box, an air nozzle, a vertical pipe elbow, a reflux inclined pipe, a reflux penetrating-through-wall pipe and a tank-external compress air control device, wherein a plurality of small holes are uniformly distributed on the mud suction pipe, the mud suction pipes are aligned in a horizontal longitudinal-transverse communication manner, and are assembled in the closing box on the middle portion position, the air nozzle is arranged inside the box, the top of the box is connected with the vertical pipe elbow, and the pipe bottom of the outlet of the reflux penetrating-through-wall pipe is slightly lower than or the same as the water surface. The surface type gas stripping micro power reflux apparatus has the following characteristics that: the structure is delicate and simple; and compared with the conventional submersible sludge discharge pump, the penetrating-through-wall reflux pump or the point-type gas stripping reflux device, and the like, the surface type gas stripping micro power reflux apparatus has characteristics of high reflux efficiency, balancing with no dead angle, no damage on the active sludge floc structure, flexible and efficient reflux control, application of a sewage treatment plant aeration air blower to supply gas, extreme low converted gas stripping energy consumption, no movement part and electrical equipment under water, and high reliability.
