Heat pipe waste heat recoverer with soft water preheating function

Abstract

The invention relates to a heat pipe waste heat recoverer, and in particular to a heat pipe waste heat recoverer with a soft water preheating function. According to the structure of the heat pipe waste heat recoverer, a soft water preheater and an evaporator are generally included, and the soft water preheater is communicated with the evaporator. A plurality of heat pipes are arranged in the evaporator, the cooling segments of the heat pipes stretch into a steam bag arranged on the evaporator, and the heating segments of the heat pipes stretch into a smoke heating cavity. In the heat pipe waste heat recoverer, the soft water preheater comprises the steam bag, and a separation plate is vertically arranged in the steam bag; the smoke heating cavity is arranged below the steam bag, and the heating pipes are evenly arranged in the end face, connected with the steam bag, of the smoke heating cavity in a penetrating manner, and are distributed on the two sides of the separation plate; the steam bag is divided into a soft water cavity and an evaporation cavity through the separation plate, and a content gauge is arranged in the position, on one side of the soft water cavity, of the shell; and a water inlet pipe communicated with the soft water cavity is arranged below the content gauge, and communicated steam holes are horizontally formed in the upper end of the separation plate.

Description

technical field [0001] The invention relates to a heat pipe waste heat recovery device, in particular to a heat pipe waste heat recovery device with soft water preheating function. Background technique [0002] With the development of industrial technology, rough industrial production methods have been gradually eliminated. Reducing industrial energy consumption, energy saving and emission reduction have become effective methods for production enterprises to reduce costs. Waste heat recovery equipment as a device that can effectively improve the utilization rate of waste heat has become Widely used in glass, titanium dioxide, brick kiln and other processing fields. Most of the existing domestic heat pipe waste heat recoverers adopt a cylindrical horizontal structure, including a soft water preheater and an evaporator. The soft water preheater is connected to the evaporator, and a heat pipe is installed in the evaporator. The cooling of the heat pipe The section extends into...
