High-flux spiral plate heat exchanger

Abstract

The invention discloses a high-flux spiral plate heat exchanger. The heat exchanger comprises a first heat exchange box, a second heat exchange box, a third heat exchange box, a first conduction pipe, a second conduction pipe, a first conduction hose, a second conduction hose, a low-temperature one-way valve and a high-temperature one-way valve. The low-temperature one-way valve and the high-temperature one-way valve are arranged on the first heat exchange box, the first heat exchange box and the second heat exchange box are connected through the first conduction pipe and the second conduction hose, the conduction pipes are used for conveying heat exchange media, the second heat exchange box and the third heat exchange box are connected through the second conduction pipe and the second conduction hose, and therefore multi-stage heat exchange is achieved, and the heat exchange effect is achieved through the principle of multiple heat exchange of one heat exchanger. An auxiliary propelling device and an auxiliary heat exchange device are further arranged on the first heat exchange box, so that the heat exchange effect can be accurately controlled. The high-flux spiral plate heat exchanger has the effect of an accurate heat exchange function.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a high-flux spiral plate heat exchanger. Background technique [0002] The crude benzene recovery section of coke oven gas is an important part of gas purification. Crude benzene, a by-product after purification, is an important chemical raw material. After refining and separation, high value-added chemical products such as toluene and xylene can be obtained, which can further produce benzene Organic compounds such as organic compounds such as cyclohexane and maleic anhydride, the products are widely used in rubber, fiber, pharmaceutical and chemical industries, and have considerable economic benefits. There are some problems in the technology and equipment of the workshop section. The flow rate of the regenerated rich oil is relatively large, and the heat exchange capacity of the lean-rich oil heat exchanger is not enough, resulting in a low temperature of the rich oil a...

Problems solved by technology

However, when using this heat exchanger, the heat exchange effect cannot be precisely controlled. It only uses the heat exchange principle and is not suitable for high-precision heat exchange instruments. Pipes will be severely corroded
