Abstract

The invention relates to a heat energy recovery device in a production line for preparing acrylic acid by an automatic propylene oxidation method, and relates to the technical field of chemical equipment. The heat energy recovery device comprises a tank body, a plurality of ring frames, infrared heating pipes, a control box and a connecting table, wherein the plurality of ring frames are embedded in the tank body at intervals, the plurality of infrared heating pipes are distributed in the middle of the ring frames at intervals, the length direction of the infrared heating pipes is the same as that of the tank body, the control box is fixedly connected to one ends of the infrared heating pipes, and the connecting table is fixedly connected to one side of the control box. The method has the advantages that the steam recovery efficiency is improved, and the secondary resource consumption is low.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a heat energy recovery device in an automatic propylene oxidation process for producing acrylic acid. Background technique [0002] The production of acrylic acid or methacrylic acid by two-step oxidation of (meth)propylene is a mature process, and the key to improving the economic efficiency of the plant is to reduce the energy consumption and human capital investment of the plant. Making full use of the reaction heat of propylene oxidation and the waste heat of oxidation tail gas incineration is the consensus of saving energy and reducing consumption in the two-step oxidation of propylene to produce acrylic acid or methacrylic acid. The heat of the propylene oxidation reaction is obtained through the molten salt in the reactor, and the cooling water is heated by the cooler to generate steam to cool the molten salt to maintain the reaction temperature of the reactor. ...
