2results about How to "Effective pollution control" patented technology

This utility model discloses a catalyst collection and conveying device at the bottom of the riser pipe of a catalytic cracking unit, belonging to the field of petrochemical technology. It includes a frame platform with a first riser pipe and a second riser pipe mounted on it. A collection hopper is fixedly connected to the bottom of both the first and second riser pipes. In this utility model, fallen catalyst dust is collected by the collection hoppers at the bottom of the first and second riser pipes. The collected catalyst dust is then driven to the inner cavity of a storage tank via a blower, a first electrically controlled valve, an exhaust pipe, a second electrically controlled valve, an upper guide pipe, and a lower guide pipe. The collection hoppers and closed conveying pipes prevent catalyst powder from floating around due to wind during discharge, effectively controlling dust pollution in the unit area, improving the working environment, and protecting equipment and personnel health.

This utility model discloses a lead-antimony slag recovery and antimony treatment system, comprising: a crushing device, a medium-frequency heating furnace, an ingot casting machine, a dust collection device, and a water cooler; the crushing device is located on the left side of the system and is connected to the feed inlet of the medium-frequency heating furnace via a belt conveyor, which is also equipped with a batching and metering device; a dust collection device is also located above the medium-frequency heating furnace; a water cooler is located on the right side of the medium-frequency heating furnace, and the water cooler is connected to the inlet and outlet water pipes of the medium-frequency heating furnace via pipelines; a system control device for controlling the medium-frequency heating furnace is located behind the medium-frequency heating furnace; an ingot casting machine is located in front of the medium-frequency heating furnace, which is used to receive the antimony liquid flowing out of the medium-frequency heating furnace. This utility model's lead-antimony slag recovery and antimony treatment system has a good antimony capture effect, with an antimony recovery rate of over 99%, and good economic benefits; the system has a compact structure, simple operation, fast processing, short process flow, and high degree of automation; it causes no environmental pollution, has low cost, and requires little investment.
