Abstract

The present invention relates to a gross aldehyde extraction equipment. The lower reaction tank and the upper reaction tank are connected through the tank body, wherein the high-pressure water inlet pipe and the discharge port are arranged on the wall of the lower reaction tank and communicate with the lower reaction tank, and the water outlet pipe, The feed port and the air pressure balance port are arranged on the upper reaction tank and communicated with the upper reaction tank. The quantitative discharge controller is rotatably arranged inside the discharge port. The tank is composed of a cylindrical body connected in series. Connected together, a first filter screen and a second filter screen are arranged in parallel in the middle of each cylindrical body, the first filter screen and the second filter screen are separated by a certain distance, and can be rotated above the upper cylindrical body A stirrer is arranged on the ground, and an opening is opened on the cylindrical body of the lower layer, and the opening is connected with a hollow tube body, and several small holes are opened on the side wall of the hollow tube body. The invention avoids the occurrence of side effects during the neutralization reaction, thereby improving the yield of the product and improving the quality of furfural.
