Catalytic cracking fume desulfuration wastewater treatment process

A catalytic cracking fume desulfuration wastewater treatment process is characterized in that wastewater is discharged to a slurry pool and is mixed with a flocculating agent, a stirrer is used for stirring the wastewater and the flocculating agent, the wastewater and the flocculating agent are mixed evenly, the wastewater after being mixed is discharged to an expansion tube type filter and is subjected to the coagulation reaction at the lower end of the expansion tube type filter, small particulate matters in the wastewater are flocculated, large flocculating bodies are formed, the solid-liquid separation is achieved through the filtration of a filtering film, thick slag and supernatant fluid are obtained, the supernatant fluid is discharged to an oxidation tank further, the thick slag is subjected to back washing and enters a subsequent filtering box, the thick slag is concentrated and dewatered in the filtering box, mud cakes which are concentrated are transported outwards, the water of dehydration returns to the slurry pool again, is mixed with the wastewater and is processed again, the false chemical oxygen demand (COD) which contains sulfite and bisulfite is oxidized and removed by the supernatant fluid in the oxidation tank, and the sewage which meets standards is discharged. Compared with the prior art, the process has the advantages that the area occupied by devices is small, the operation cost is low, the solid and the liquid can be separated completely, the working environment of workers is good, device parameters can be set in accordance with parameters of different materials, and the application is wide.

Process for removing smoke dust by wet ammonia flue gas desulphurization and device thereof

The invention provides a process for removing smoke dust by wet ammonia flue gas desulphurization. The smoke dust removing process comprises two processes, namely, smoke dust removal and ammonium sulfate post-treatment, wherein the ammonium sulfate post-treatment process is that desulfurated ammonium sulfate slurry which is generated by a desulphurization system is delivered to a cyclone separator, a lower overflow vent of the cyclone separator is connected with the inlet of a centrifugal machine, and a solid outlet of the centrifugal machine is connected with a drier; and the smoke dust removing process is that liquid of an upper overflow vent of the cyclone separator and a liquid outlet of the centrifugal machine are connected with filtering separation equipment, and liquid enters a recirculating tank or a liquid tank for next circulation after dust in the liquid is removed by the filtering separation equipment. A device for removing dust by wet ammonia desulphurization comprises the cyclone separator, a centrifugal machine, the drier, the filtering separation equipment, an ash settling pond, a circulating tank or the liquid tank with a stirring device, is used for combining theammonium sulfate post-treatment and dust removal, and has simple process and system, small occupied area and low operation cost.

Automatic molding machine for automobile interior part felt

The invention discloses an automatic molding machine for an automobile interior part felt and belongs to molding machinery of automobile interior parts. The automatic molding machine comprises a frame base, a rail assembly, three lower molds, a group of lower mold station moving mechanisms, a group of lower mold station reversing mechanisms, a pair of pressing upper molds, a feed supplementing mechanism and a net laying mechanism. The rail assembly consists of a group of longitudinal guide rails and a group of transverse guide rails, and is arranged on the frame base, and the longitudinal guide rails and the transverse guide rails are vertically staggered to form a feed complementing station, a pre-pressing station, a net laying station and a molding station. The three lower molds which are provided with a lower mold base are arranged on the rail assembly. The group of lower mold station moving mechanisms are arranged on the frame base. The group of lower mold station reversing mechanisms are arranged on the frame base and matched with the intersection formed by vertically intersecting the transverse guide rails and longitudinal guide rails. The pair of pressing upper molds which is provided with the upper mold base is arranged on the frame base, wherein one pressing upper mold corresponds to the upper part of the pre-pressing station, and the other pressing upper mold corresponds to the upper part of the molding station. The feed complementing mechanism is arranged on the frame base and corresponds to the upper part of the feed complementing station. The net laying mechanism is arranged on the frame base and corresponds to the upper part of the net laying station. The automatic molding machine for the automobile interior part felt has the advantages of high integration degree, small occupancy area, a few on-line workers, high production efficiency and energy conservation.
