Problems solved by technology

[0002] Oil-free vertical vacuum pumps are often used in chemical production to recover volatile solvents. The vacuum pump is a rotary variable displacement vacuum pump that must be used with a backing pump. It can be used in a wide pressure range and has a large pumping speed. However, during use, the exhaust port of the vacuum pump may inevitably discharge part of the solvent vapor due to incomplete sealing, resulting in solvent loss and polluting the air environment

Abstract

The invention discloses an exhaust gas recycling device for a vacuum pump. The exhaust gas recycling device comprises the vacuum pump and an exhaust gas recycling pipe, wherein an exhaust gas discharging opening of the vacuum pump is connected with the exhaust gas recycling pipe; the recycling device further comprises an exhaust pipe and a condensing device; the exhaust pipe is mounted between the exhaust gas discharging opening of the vacuum pump and the exhaust gas recycling pipe; and the condensing device is mounted on the exhaust pipe. The exhaust gas recycling device for the vacuum pump is additionally equipped with the exhaust pipe and the condensing device, so that solvent steam is cooled in an accelerated manner, and the possibility of leakage of the solvent steam is reduced.

Description

technical field [0001] The invention relates to a tail gas recovery device, in particular to a tail gas recovery device for a vacuum pump. Background technique [0002] In chemical production, oil-free vertical vacuum pumps are often used to recover volatile solvents. The vacuum pump is a rotary variable-capacity vacuum pump that must be used in conjunction with a backing pump. However, during use, the exhaust port of the vacuum pump may inevitably discharge part of the solvent vapor due to incomplete sealing, resulting in solvent loss and polluting the air environment. Contents of the invention [0003] The object of the present invention is to provide a tail gas recovery device for a vacuum pump in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] A tail gas recovery device for a vacuum pump, comprising a vacuum pump and a tail gas recovery pipe, the exhaust gas discharge port...
