The utility model relates to the technical field of slag treatment, in particular to a water reducing box for a slag wet separation process, which comprises a box body, the box body comprises a plurality of sub-box bodies which are sequentially connected, and the bottom wall of the box body is an inclined surface which is inclined downwards; a communicating hole is formed in the bottom of each sub-box body, and each sub-box body is communicated with the adjacent sub-box body through the corresponding communicating hole; the box body comprises a water inlet, an overflow port and a water outlet; the water inlet located in the top of the box body is used for conveying water flow into the box body, the water outlet located in the bottom of the box body is used for conveying treated water flow to the outside of the box body, and the water inlet and the water outlet are arranged in a staggered mode, so that the flowing path of the water flow is changed; the overflow opening is formed in the top of the box body, and when the liquid level exceeds the preset height, redundant water flow is discharged out of the box body through the overflow opening. The water reducing box can improve water flow control, reduce water flow impact and turbulence phenomena, and improve the precipitation efficiency and recovery rate of metal particles and sand grains.

The invention discloses molybdenum concentrate hydrometallurgy waste gas treatment equipment, and relates to the technical field of waste gas treatment. The filtering mechanism is used for filtering particles in the hydrometallurgy waste gas, and the connecting frame is fixedly connected to the outer side face of the filtering mechanism, due to the fact that MoO-containing dust, mineral powder which does not completely react or other metal oxide particles can be generated when molybdenum concentrate MoS is roasted, the MoO-containing dust, the mineral powder which does not completely react or other metal oxide particles can be generated when the molybdenum concentrate hydrometallurgy waste gas is treated. According to the molybdenum concentrate hydrometallurgy waste gas treatment device, solid particles and dust in waste gas need to be filtered, the waste gas can be preliminarily filtered when molybdenum concentrate hydrometallurgy waste gas is treated by arranging the filtering mechanism, large-particle metal oxide particles and mineral powder generated in the waste gas due to roasting are collected, and the waste gas is recycled. And the preliminarily filtered waste gas flows to the next treatment step, so that the effect of recycling metal particles and mineral powder in the molybdenum concentrate hydrometallurgy waste gas is achieved.

A process and a device for preparing ultra-clean high-purify ammonia water are provided. The ultra-pure high-purity ammonia water is obtained by heating and gasifying, pressurizing to remove impurities, washing with ultrapure water to remove impurities, purifying with a molecular sieve adsorption column, absorbing with ultrapure water and filtering with an ultrafiltration membrane. The obtained ultra-pure high-purity ammonia water has high product quality and simple process. The obtained ultra-pure high-purity ammonia water has lower contents of metals and particles, the process is safe and reliable, and has low energy consumption. The process has no waste discharge, and is environmentally friendly and practical.

The utility model relates to plate pickling treatment technical field discloses a kind of pickling spray production line for plate, including bottom plate, the top of the bottom plate is fixedly connected with pickling spray tank, the both sides of pickling spray tank are fixedly connected with conveying roller stand and discharge roller stand in the top of the bottom plate, so that the device can filter the metal particles in waste liquid by filter plate, then the filtered waste liquid is pumped into the inside of circulating recovery tank by pumping, and the acidity of waste liquid in the inside of circulating recovery tank is detected using PH sensor, when acidity is too low, it can add acidic solution with higher concentration to the inside of circulating recovery tank by liquid supplementing tank, so that the acidity of solution in the inside of circulating recovery tank can be kept in suitable pickling range, finally, pickling and spraying treatment of plate can be quickly carried out using high-pressure atomizing nozzle at the bottom of spray pipe, so that the acid liquor recovery rate of the device is greatly improved.
