The utility model relates to waste liquid treatment technical field discloses neutralization buffer cabinet and marine engine, wherein the neutralization buffer cabinet, including: cabinet, the inside of cabinet is divided into first oil removal area and second oil removal area by partition, and the bottom of partition is equipped with the communicating port of intercommunication of first oil removal area and second oil removal area, first oil removal area interval is equipped with waste liquid inlet and oil outlet, and the oil outlet is installed in the upper of waste liquid inlet and is located the oil layer position of first oil removal area, and the bottom of first oil removal area is equipped with first aeration disc, second oil removal area interval is equipped with lye inlet and overflow port, and the bottom of second oil removal area is equipped with second aeration disc, the utility model discloses utilize the difference of oil -water density in first oil removal area, and the oil and oil residue that float up are discharged through oil outlet, realize oil liquid preliminary separation, in second oil removal area, and the oil grease in waste liquid happens saponification reaction by the lye that is passed in, further remove the oil grease in waste liquid, and the oil grease removal effect is better.

The application relates to the field of N,N-dimethylformamide, and specifically provides a high-purity N,N-dimethylformamide synthesis system and method, which comprises a fixed bed reactor; a cooling pipe is fixedly connected in the fixed bed reactor; a connecting pipe is communicated in the cooling pipe; and a gas pump is fixedly connected to one end of the connecting pipe away from the cooling pipe; when the fixed bed reactor is working, the temperature inside the fixed bed reactor continuously rises; when the temperature rises to more than 400 DEG, a first control valve on a water inlet pipe is opened; then cold water is injected into the cooling pipe from the water inlet pipe; and then the first control valve is closed; at this time, the cooling pipe absorbs the heat inside the fixed bed reactor due to the cold water, so that the temperature inside the fixed bed reactor is reduced, and the problems of catalyst coking due to local overheating, increased side reactions and reduced catalyst utilization rate when the temperature inside the reactor is too high are reduced.

The invention relates to the technical field of hard alloy column tooth passivation, and particularly discloses a hard alloy column tooth passivation machine tool which comprises a frame body, an inner cylinder is rotationally arranged at the upper end of the frame body, a cylinder cover is hinged to the upper end of the inner cylinder, a clamping assembly is arranged on the bottom wall of the inner cylinder, a liquid storage tank is arranged on one side of the frame body, and a water pump is arranged on one side of the liquid storage tank. The water inlet end of the water pump communicates with the liquid storage tank, the water outlet end of the water pump communicates with the middle of the bottom wall of the inner cylinder, and an electrolytic passivation mechanism is arranged on the inner bottom wall of the inner cylinder; the cylindrical teeth are placed in the inner cylinder, the clamping assembly can stably clamp the cylindrical teeth, then the cylinder cover is closed, the water pump is started, the water pump on one side of the frame body pumps electrolyte in the liquid storage box into the middle of the bottom wall of the inner cylinder, and at the moment, the electrolytic passivation mechanism can make the polished ends of the cylindrical teeth generate uniform passivation films; and the scraping effect and scraping efficiency of the passivation film are improved, so that the passivation effect of the column teeth is improved, the corrosion resistance of the column teeth is improved, and the service life of the column teeth is prolonged.

The utility model relates to the field of sewage treatment, in particular to a circulating aeration device for sewage treatment, which comprises an aeration frame, a main body for aeration installation, a servo motor, a transmission rod fixedly arranged above the aeration frame and used for an output end, a first stirring disc fixedly arranged at the other end of the transmission rod, and a second stirring disc fixedly arranged at the other end of the transmission rod, and a second stirring disc is fixedly mounted at the bottom of the first stirring disc. The circulating aeration device for the sewage treatment is provided with the first stirring disc, the second stirring disc, the water diversion helical teeth, the first side supporting plate, the pressurizing air pump, the air suction pipe, the air supply pipe, the water storage box and the pressurizing water pump, so that when the circulating aeration device for the sewage treatment is used, water flow in the aeration tank is stirred through the rotation of the first stirring disc and the second stirring disc; water diversion helical teeth are arranged outside the first stirring disc and the second stirring disc, so that the stirring and scattering force of the first stirring disc and the second stirring disc on the liquid is enhanced.
