Embodiment

[0023] refer to Figure 1-4 , an energy-saving and safe explosion-proof reboiler, comprising a reboiler shell 1, the bottom wall of the reboiler shell 1 is fixedly connected with a feed pipe 2, and the top wall of the reboiler shell 1 is fixedly connected with a discharge pipe 3. Pipe 6, oil inlet pipe 5, gas outlet pipe 7, heat exchange pipe 4 is arranged inside the reboiler shell 1, and the end of the balance pipe 6 away from the reboiler shell 1 is fixedly connected with a gas storage chamber 8, where the gas storage chamber 8 The side wall is welded to the side wall of the oil inlet pipe 5, and the end of the gas outlet pipe 7 away from the reboiler shell 1 runs through and extends to the inside of the gas storage chamber 8. The balance pipe 6 is provided with a pressure sensing device, and the gas storage chamber 8 is provided with a control device.

[0024] The air pressure sensing device includes a slide plug 9 in the balance tube 6, the cross section of the slide plug ...

Abstract

The invention discloses an energy-saving safe explosion-proof reboiler which comprises a reboiler shell, a feeding pipe is fixedly connected to the bottom wall of the reboiler shell in a penetrating mode, a discharging pipe, a balance pipe, an oil inlet pipe and an air outlet pipe are fixedly connected to the top wall of the reboiler shell in a penetrating mode, and a heat exchange pipe is arranged in the reboiler shell. The end, away from the reboiler shell, of the balance pipe is fixedly connected with a gas storage chamber in a penetrating mode, the side wall of the gas storage chamber is welded to the side wall of the oil inlet pipe, the end, away from the reboiler shell, of the gas outlet pipe extends into the gas storage chamber in a penetrating mode, a gas pressure sensing device isarranged in the balance pipe, and a regulation and control device is arranged in the gas storage chamber. The reboiler has the advantages that internal small-amplitude overpressure can be allowed, self-regulation and control can be carried out when the pressure is too large, the reboiler cannot be directly closed, production is not affected, the reboiler is directly closed when the pressure is too large, the explosion risk is avoided, meanwhile, heat can be recycled, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of chemical production equipment, in particular to an energy-saving, safe and explosion-proof reboiler. Background technique [0002] Reboiler, also known as reboiler, is similar in structure to condenser, but one is used to cool down, while reboiler is used to heat up and vaporize. Reboiler is often used in combination with rectification tower in chemical production. Reboiler It can vaporize the heavy components at the bottom of the rectification tower, the gas phase flows upwards, and the light component liquid phase from the reflux tank can be partially vaporized and partially condensed on the tray or packing layer for many times, so that the mixture can be separated with high purity . [0003] In the prior art, the existing reboiler does not have good explosion-proof measures. Often, a pressure sensor is simply installed inside the reboiler. Therefore, we propose an energy-saving and safe explosion-pro...
