TECHNICAL FIELD
[0001] The utility model relates to a reflux tank equipment field, concretely to a light white oil fractionating column top reflux tank. BACKGROUND
[0002] White oil needs to be purified when processing, and the purification of white oil is usually carried out by fractionation. The existing white oil is heated by a reflux tank to separate gas and liquid. In order to prevent white oil from leaking from the round hole to the discharge port, the storage capacity of white oil in the existing reflux tank cannot exceed half of the tank body, which increases the frequency of unloading and affects the efficiency.
[0003] According to the patent document with the existing publication number CN216653437U, a light white oil fractionating column top reflux tank equipment is disclosed, which includes a bottom plate and a tank body. The tank body is placed vertically, and the upper end of the tank body is provided with a feed pipe and a gas outlet pipe. The lower end of the tank body is provided with an oil discharge pipe. The lower end of the tank body is coaxially fixed with a rotating shaft, and the rotating shaft is rotatably connected with the bottom plate. One side of the tank body is provided with a heating assembly. The heating assembly includes a fixed frame fixedly connected with the bottom plate, and a plurality of heating pipes are installed on the fixed frame. When this technical solution is used, the tank body is controlled to rotate to achieve uniform heating, thereby achieving fractionation of crude oil and achieving gas-liquid separation. The storage capacity of the liquid in the tank body is increased to reduce the frequency of oil unloading. For the above technical solution, although uniform heating is achieved, the inner wall of the tank body cannot be scraped and cleaned after white oil purification, which is inconvenient during use.
