The application discloses a mineralization treatment method of organic waste liquid, and belongs to the technical field of radioactive waste treatment. The organic waste liquid contains uranium, tributyl phosphate and diluent. The mineralization treatment method comprises the following steps: the organic waste liquid is separated through short-path molecular rectification to obtain a diluent fraction and a tributyl phosphate fraction; the tributyl phosphate fraction is reacted with alkali liquor to generate an alkaline hydrolysis product containing dibutyl phosphate salt, n-butanol, water and uranium; the n-butanol is collected through condensation reflux; and the remaining alkaline hydrolysis product is treated through two-stage oxygen-controlled incineration, so that phosphate glass and qualified flue gas are finally obtained. The mineralization treatment method has the advantages of no corrosion, short process, high-efficiency mineralization and stabilization of the waste liquid, direct disposal of the product, consideration of resource recovery and radioactive safety, and easy industrialization.

The invention relates to the technical field of industrial salt treatment, in particular to waste salt cleaning equipment and method. The waste salt cleaning equipment comprises a cleaning tank, a feeder and a spraying device; the feeder is configured to be capable of conveying waste salt and saturated salt water in the cleaning tank from the inlet end to the outlet end and enabling the waste salt to roll over in the conveying process, and the saturated salt water sprayed by the saturated salt water nozzle can wash the waste salt in the rolling-over process; the waste salt cleaning device has the advantages that waste salt is continuously turned and rubbed through rotation and stirring effects generated in the conveying process of the feeder, the surfaces of salt particles can be deeply cleaned in combination with uniform spraying formed by the saturated salt water nozzles, soluble impurities contained in the salt particles and attached insoluble substances are effectively removed, and therefore cleaning thoroughness and consistency are remarkably improved.

The present application relates to the technical field of tobacco production, and provides a wet dust collector, which comprises a dust removal cylinder, a flue gas inlet installed at the lower part of the dust removal cylinder, and a spraying component installed in the flue gas inlet and used for spraying washing liquid into flue gas, a fan is installed at the top of the dust removal cylinder, and a flue gas outlet is installed on the fan; a micro-permeation liquid membrane assembly is arranged on the inner top of the dust removal cylinder, and the micro-permeation liquid membrane assembly is connected with an inner cavity water supply assembly installed on the inner top of the inner wall of the dust removal cylinder; the micro-permeation liquid membrane assembly comprises a cylindrical sleeve arranged on the inner top of the dust removal cylinder and a sealing ring used for connecting the cylindrical sleeve with the inner cavity water supply assembly. In use, through the cooperation of variable-pitch spiral agglomeration and micro-permeation liquid membrane capture, the present application actively promotes the agglomeration and weight gain of superfine smoke dust, the micro-permeation liquid membrane provides a stable and reliable final capture surface, and the combination of the two ensures that the outlet smoke dust concentration is stable and meets the increasingly strict ultra-low emission requirements of the tobacco industry.

The invention discloses a wastewater multi-treatment system for pollution abatement, and belongs to the technical field of wastewater and waste gas treatment, the wastewater multi-treatment system for pollution abatement comprises an absorption water tank for ammonia gas absorption treatment, the absorption water tank is provided with a waste gas collecting and conveying gas channel, a heat exchange absorption cover is connected with a conversion absorption disc through a conversion device, and the conversion absorption disc is provided with a plurality of heat exchange channels. Residual hydrogen and ammonia gas which are not fully absorbed in the absorption water tank are sucked into the treatment system again through the concentration opening in the waste gas collecting and conveying gas channel by means of airflow suction force, circulation treatment is formed, and the hydrogen gathering cover on the top of the equipment naturally floats and is enriched by means of the physical characteristic that hydrogen is low in density. By arranging the valve capable of being controlled to be opened and closed, high-concentration hydrogen is guided into the combustion device and is mixed with air sucked in through the inclined oxygen inlet to be safely combusted, the explosion hidden danger caused by hydrogen accumulation in tail gas is thoroughly eliminated, purification and final treatment of hydrogen are achieved, and the safety of exhausted gas is ensured.

The application discloses an intelligent feeding device and method based on low-soap emulsified antioxidant styrene-butadiene rubber production and relates to the technical field of rubber production. The intelligent feeding device comprises a mixing module, and a feeding mechanism is arranged above the mixing module to realize low-shear, impact-free and uniform dispersion of the antioxidant emulsion into the latex. The feeding mechanism comprises an antioxidant feeding unit arranged at the top of the mixing module. The antioxidant emulsion slowly penetrates into the latex in the form of extremely small droplets through the microporous tube in the antioxidant feeding unit, replacing the traditional mechanical stirring or high-pressure injection mode. The dispersion mode provided by the microporous tube hardly produces turbulent shear and high-speed impact, and the technical problem that the conventional mode causes the particle rupture and coalescence to form gel under the condition of low soap due to the strong shear force to destroy the thin emulsifier layer on the surface of the latex particles is solved from the root, thereby affecting the product quality and blocking the equipment.
