6 results about "Retort" patented technology

The invention discloses a drum-type carbon black ozonation retort which can perform uniform rolling around a fixed shaft forming a certain included angle with the horizontal direction to facilitate flowing of carbon black. During oxidation of carbon black, granular carbon black flows into a retort body through a material conveying pipe which forms a certain angle with the axial position of the feeding-side end surface of the retort, ozone axially flows into the retort body from the end surface of the same side through a gas conveying pipe of which the tail end is closed, vertically sinks and then is buried at the bottom of the carbon black layer in the horizontal direction of the wall of the retort, the gas conveying pipe, of which the tail end is closed, in the horizontal direction of the wall of the retort is bestrewed with lots of micropores, and on dependence of pressure of an ozone generator, ozone is discharged out from the micropores to be subjected to oxidation reaction with carbon black. After oxidation of carbon black is finished, carbon black flows out from a discharge opening in the bottom of the end surface of the other side while waste gas is discharged out from an exhaust hole in the upper part of the end surface of the same side. The drum-type carbon black ozonation retort is wholly made of stainless steel, realizes a continuous controllable production process, ensures that oxidized carbon black is uniform and stable in quality, and facilitates equipment maintenance and safety production.

The invention discloses a sewage treatment system for a printing plant. The sewage treatment system comprises a distillation retort, wherein the bottom part of the distillation retort is provided with an electric heater; a de-foaming agent storage pot is communicated with the distillation retort; one end of a condensing pipe is connected with the top end of the distillation retort, and the other end of the condensing pipe is connected with an oil-water separator; the condensing pipe is provided with cooling equipment; the oil-water separator is communicated with a sand filter and an anaerobic hydrolysis pond sequentially. The sewage treatment system is reasonable in design; through treating the sewage of the printing plant by the distilling method, a printing ink detergent is removed from the waste solution, and then the toxic impurities such as ammonia and chlorine are effectively filtered out from the sewage by the filter sands; the filter effect is good, the sewage after being treated can be recycled as industrial water, the operation cost of the sewage treatment system is low, and the purpose of saving the water resource can be realized.

The invention relates to walling glue prepared by adopting waste materials and a preparation method thereof. The glue comprises raw materials of 45-55 portions of special base glue mother liquid, 6-10 portions of special organosilicone coupling agent, 10-15 portions of natural emulsion, 1.5-3 portions of salt polyacrylate, 0.5-1 portion of potassium hydroxide, 0.5-1 portion of methyl dinaphthyl sodium sulfonate, 1.5-3 portions of zinc oxide and 1-6 portions of calcium carbonate, wherein the base glue mother liquid is prepared by adopting No.200 solvent naphtha to dissolve waste polystyrene and waste rubber tires, and the special organosilicone coupling agent is obtained in such a way that asphaltum and waste glass react in a high-temperature reactor. The raw materials are put in a retort and are evenly stirred at the temperature of 65-100 DEG C so as to be processed by polymerization for 2 hours, and a binder of the invention is obtained after cooling the product of reaction. The invention adopts waste plastic and rubber as raw materials, thereby being beneficial to reducing environmental pollution, saving material resources, having low production cost and being suitable for the binding of various materials, in particular the binding of inorganic materials such as walls, and the like.
