This utility model discloses an ozone advanced oxidation tail gas recovery and utilization device, including an ozone tail gas inlet pipe and a primary purification tower and a secondary purification tower connected in sequence. The rear end of the secondary purification tower is connected to an ozone buffer tank. The primary and secondary purification towers are connected to the ozone tail gas inlet pipe through an ozone circulation pipe. Both the primary and secondary purification towers are connected to sodium hydroxide dosing tanks. This application uses a secondary ozone purification tower to purify the tail gas after ozone catalytic oxidation, recover and utilize the remaining ozone, improve ozone utilization rate, and reduce costs. At the same time, it absorbs the carbon dioxide after catalytic oxidation to produce a high-purity sodium carbonate solution for downstream use as a raw material, achieving waste resource recycling.

The utility model discloses waste water collecting equipment for a dehydration spiral device, which relates to the field of dehydration spiral equipment and comprises a water storage tank, an inner tank is arranged in the water storage tank, a side plate is arranged on one side of the top end of the water storage tank, and a water attaching cylinder is arranged on the other side of the side plate. The waste water collecting device comprises a water adding cylinder, a spiral cylinder is arranged on one side of the water adding cylinder, a sealing cover is arranged on the other side of the water adding cylinder, a branch water pipe is arranged on the other side of the sealing cover, an outer layer cylinder is arranged at the top end of the branch water pipe, and an inner layer cylinder is arranged in the outer layer cylinder. A water blocking barrel in the water adding barrel guides overflowing water back into the spiral barrel, a branch water pipe inserted into the spiral barrel guides waste water into the water attaching barrel, and a sealing cover is arranged to prevent the waste water from overflowing from the interior of the water attaching barrel, so that the waste water can be collected to the maximum extent.
