The present invention discloses a desulfurization and decarburization rotating bed apparatus and method, the apparatus is a spherical reactor structure, and the apparatus comprises: a decarburization unit, which comprises a rotating shaft and a tree-shaped baffle plate, and the rotating shaft is vertically arranged in a spherical reactor in a penetrating manner; the whole tree-shaped baffles are tree-shaped and are arranged in a layered mode in the circumferential direction of the rotating shaft, the number of the baffles in each layer is multiple, the baffles are evenly arranged at intervals, and deviation angles are formed in the baffles of the adjacent layers in the radial direction. The connecting rod of the lower-layer baffle is longer than that of the upper-layer baffle; in the rotating process of the rotating shaft, the CO2 absorbent impacts the baffle plate from top to bottom, the baffle plate crushes liquid into fine fog drops and makes the fog drops descend spirally, and gas-liquid mass transfer is performed between the fog drops and flue gas from bottom to top while the fog drops descend; and the desulfurization unit is positioned below the decarburization unit and is used for forming contact mixing of the spirally ascending flue gas and the spirally descending SO2 absorbent. Desulfurization and decarburization processes are integrated in the same spherical reactor, so that the integration of desulfurization and decarburization is realized.

The application discloses a built-in multi-pipe supersonic condensation-cyclone-coalescence filter, which comprises a shell, a cyclone pre-separation module, a supersonic nozzle steam condensation module, a multi-stage guide vane type mist cyclone separation module and a coalescence filter core filter module are sequentially arranged in the shell from bottom to top. The filter can not only separate free liquid droplets carried in natural gas, but also deeply remove lubricating oil steam, hydrocarbons and water vapor contained in the natural gas through phase change condensation. The filter has the characteristics of large operation flexibility and high separation efficiency.

The utility model discloses a temperature control device for a supporting and pushing bearing bush of an air blower, and relates to the technical field of air blowers, the temperature control device comprises a supporting and pushing bearing bush assembly, the supporting and pushing bearing bush assembly comprises a supporting and pushing bearing bush body, and a strengthening mechanism is installed in the supporting and pushing bearing bush body. During high-load operation, the load bearing capacity of the thrust bearing bush is enhanced, axial force of a rotor part can be offset, the positioning grooves and the ventilation grooves are formed between the two main thrust surfaces, ventilation is kept between one side of the thrust bearing bush body and the connecting position, heat accumulation is reduced, the heat dissipation fins are arranged on the outer side of the thrust bearing bush body, and the service life of the thrust bearing bush body is prolonged. The supporting and pushing bearing bush is used for increasing the contact area between the outer side of a supporting and pushing bearing bush body and air, improving the heat dissipation efficiency, improving the natural cooling effect, reducing the frequency of replacing the supporting and pushing bearing bush body in the later period and achieving the purposes of long-period equipment operation and productivity improvement.
