Abstract

The invention discloses a shell and tube heat exchanger and a using method thereof in mariculture. The shell and tube heat exchanger comprises a shell tube and a plurality of heat exchange tubes. Shell tube flange roots, tube plates, tube boxes, end plates, transition tubes and gas-liquid conveying tubes are symmetrically arranged at two ends of the shell tube. The shell tube, the shell tube flange roots, the tube plates, the tube boxes and the end plates are connected in sequence. Two transition tubes are installed on the end plates, the gas-liquid conveying tubes are installed on every transition tube, inlaying concave parts are arranged on the inner sides of the tube boxes, flow equalizing plates are installed on the inlaying concave parts and are provided with a plurality of flow equalizing holes, and a plurality of baffling plates are installed on a pipe wall on the inner side of the shell tube. The shell and tube heat exchanger is simple and reasonable in structure and convenient to use, saves energy remarkably when applied to mariculture, and is good in heat exchange effect.

Description

[0001] technical field [0002] The invention belongs to the technical field of seawater aquaculture equipment, and in particular relates to a shell-and-tube heat exchanger applied in seawater aquaculture and a use method thereof. [0003] Background technique [0004] With the continuous expansion of my country's mariculture industry, energy is relatively tight. Among the existing technologies, the heat exchanger for mariculture is mainly based on evaporators, and it can only meet the needs of seafood aquaculture ponds, but cannot meet the needs of seawater heating in winter during mariculture. system, and cannot be applied to large-scale marine aquaculture farms. The heat exchange efficiency is low. The shell, tube sheet, and heat exchange tubes of the heat exchanger cannot withstand the corrosion of chloride ions in seawater, and their service life is short. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems in the...
