Embodiment 1

[0021] When in use: the mixed gas enters the heat exchange tube B 22 from the gas inlet 1, enters the gas-liquid separation chamber 7 after heat exchange, the non-condensable gas is discharged through the gas outlet 2, and the condensate flows into the reactor 11 or the recovery kettle 12 through the reflux port 3 . The heat exchange medium enters the Y-shaped heat exchanger 10 from the heat exchange medium inlet 4 , and the heat exchange medium flows out from the heat exchange medium outlets 5 and 6 .

Embodiment 2

Embodiment 3

[0024] The process flow form of the Y-shaped heat exchanger 10 is not limited to the above-mentioned process flow, and the related processes using the Y-shaped heat exchanger are all included.

Abstract

The invention discloses a Y-shaped heat exchanger and a reactor with a heat exchange device.The Y-shaped heat exchanger comprises a heat exchanger shell (9), a gas-liquid separation cavity (7), a heat exchange tube A (21) arranged downwards along the horizontal plane, a heat exchange tube B (22) arranged upwards along the horizontal plane and a heat exchange tube C (23) arranged upwards along the horizontal plane, and the heat exchanger shell (9), the heat exchange tube A (21), the heat exchange tube B (22) and the heat exchange tube C (23) form a heat exchange cabin (15); the heat exchange tube A (21), the heat exchange tube B (22) and the heat exchange tube C (23) are respectively communicated with the gas-liquid separation cavity (7); the lower end of the heat exchange tube A (21) is provided with a backflow port (3), the upper end of the heat exchange tube B (22) is provided with a gas inlet (1), and the upper end of the heat exchange tube C (23) is provided with a gas outlet (2). The device is used for the physical and chemical reaction process, dangerous gas gathering can be completely avoided, and the gas-liquid separation effect and the heat exchange effect are guaranteed.

Description

technical field [0001] The invention relates to the field of heat exchange in chemical production, in particular to a Y-shaped heat exchanger for heat exchange and gas-liquid separation and a reactor with a heat exchange device. Background technique [0002] The heat exchangers currently used mainly use the heat exchange medium to heat or cool the required medium, such as U-shaped or shell-and-tube heat exchangers. In the industrial production process involving physical and chemical reactions, due to the generation of a large amount of gas insoluble in the solvent, or gas that cannot be condensed, the current U-shaped or tube-and-tube heat exchangers cannot achieve complete drainage and exhaust. the goal of. [0003] In the currently used U-shaped or tube-and-tube heat exchangers, some gas will accumulate inside the heat exchanger during the physical and chemical reaction process, and some of them need to be replaced by a large amount of nitrogen to ensure the safety of the...
