Abstract

The invention discloses a heat recovery device and method for chemical production, and belongs to the field of chemical equipment. Comprising a liquid inlet device, a collecting tank, a bracket I, a heat collecting tank, a heat exchange rod, a connecting pipe I, a valve I and a waste liquid tank, the lower end of the liquid inlet device is fixedly connected to the upper end of the collecting tank, the lower end of the collecting tank is fixedly connected with a support I, and the support I is connected to the upper end of the heat collecting tank through bolts; one end of the heat exchange rod is arranged in the liquid inlet device, and the other end of the heat exchange rod penetrates through the collecting tank and is arranged in the heat collecting tank; one end of the connecting pipe I is fixedly connected to the lower end of the liquid inlet device, the other end of the connecting pipe I is fixedly connected into the waste liquid tank, and a valve I is arranged on the connecting pipe I. According to the waste liquid heat preservation device, impurities can be removed, heat preservation can be conducted on waste liquid through heat of the impurities, when the impurities are few, heat preservation can be conducted on the filtering device through residual heat of the waste liquid in the waste liquid tank, energy is reasonably utilized, and heat loss in the waste liquid can be reduced.

Description

technical field [0001] The invention relates to a heat recovery device and recovery method for chemical production, belonging to the field of chemical equipment. Background technique [0002] In the chemical production process, a large amount of waste liquid will be produced, and a large amount of heat will be retained in the waste liquid.
