Chemical heat exchanger

Abstract

The invention discloses a chemical heat exchanger. The chemical heat exchanger structurally comprises a heat exchanger body, a liquid inlet, a liquid outlet, heat exchange pipes, baffle plates, an exhaust port, a shell pass pipe connector and supporting legs; the liquid inlet is formed in the left side of the top of the heat exchanger body, the exhaust port is formed in the right side of the top of the heat exchanger body, the shell pass pipe connector is arranged on the left side of the bottom of the heat exchanger body, the liquid outlet is formed in the right side of the bottom of the heatexchanger body, heat exchange pipes are distributed inside the heat exchanger body, and baffle plates are distributed in the middle of the heat exchange pipes; and a polyurethane waterproof heat preservation layer is connected to the outer side of the heat exchanger body in a sleeved mode, an epoxy anti-corrosion coating is arranged on the outer side of the polyurethane waterproof heat preservation layer, supporting legs are distributed at the bottom of the heat exchanger body, and fixed bottom foots are arranged at the bottom of the supporting legs. According to the chemical heat exchanger, the thermal insulation performance is high, the waterproof performance is high, the application range is wide, the corrosion resistance is strong, the acid and alkali corrosion can be avoided, the useis durable, and the stably support is facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a chemical heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . Heater A heater heats the fluid to the necessary temperature without a phase change in the heated fluid. Preheater The preheater preheats the fluid to provide standard process parameters for process operations. Superheater A superheater is used to heat a fluid (process gas or steam) to a superheated state. Evaporator The evaporator is used to heat the fluid to a temperature above the boiling point to make the fluid evaporate, generally w...

AI Technical Summary

Problems solved by technology

[0003] The existing chemical heat exchangers have poor anti-corrosion performance, no corrosion resistance, low strength, low thermal insulation performance and waterproof performance, and the stability of the support on the ground is not high, which will generate a large vibration feeling, which is difficult to meet the requirements of the existing chemical industry. needs
