Waste gas recovery device for normal butane production

Abstract

The invention belongs to the technical field of waste gas treatment equipment, and particularly relates to a waste gas recovery device for normal butane production. The waste gas recovery device for normal butane production comprises a gas inlet pipeline, a combustion device, a heat exchange device, a condensation device, a circulating device, a drying device and a filtering device, wherein the combustion device comprises a combustion chamber; the gas inlet pipe is arranged on one side of the combustion chamber; a fuel supply device and an oxygen supply device are arranged on the combustion chamber; the combustion device is arranged in the combustion chamber; a gas outlet pipeline is arranged at the top end of the combustion chamber and is connected with the condensation device; the heat exchange device is arranged on the gas inlet pipeline, the combustion chamber and the gas outlet pipeline; the circulating device is arranged on the condensation device; the condensation device is connected with the drying device; and the drying device is connected with the filtering device. The waste gas recovery device for normal butane production provided by the invention can be used for effectively purifying waste gas and utilizing energy at the same time so as to be energy-saving and environmental-friendly.

Description

technical field [0001] The invention relates to the related field of waste gas recovery equipment, in particular to a waste gas recovery device for n-butane production. Background technique [0002] Butane is colorless with a slight unpleasant odour. Insoluble in water, soluble in alcohol, chloroform. Flammable and explosive. In 608, the Ministry of Health approved the use of food industry processing aids. It can be used as solvent, refrigerant and raw material for organic synthesis. Oilfield gas, wet natural gas and cracked gas all contain n-butane, which is obtained by separation. N-butane is used as a raw material for the production of maleic anhydride. In order to ensure the purity of maleic anhydride products, it is necessary to strictly control the purity of n-butane. The existing separation and purification of n-butane are mostly produced by fractional distillation. [0003] Existing waste gas treatment methods generally adopt combustion treatment, but most of t...

Problems solved by technology

[0003] Existing waste gas treatment methods generally adopt combustion treatment, but most of the existing combustion devices are not equipped with preheating devices and energy recovery devices, resulting in the need to consume a lot of fuel and waste resources, and the condensation effect of the condenser is poor. Now we design a Butane production uses exhaust gas recovery device to solve the above problems
