Embodiment 1

[0016] This embodiment is a method for recovering active components of multi-component, high-concentration, low-flow, intermittent organic waste gas. The equipment is connected as figure 1 As shown, for platform oil and gas recovery, multi-component, high-concentration, low-flow intermittent organic waste gas has a complex composition, mainly composed of alkanes, olefins, and non-methane total hydrocarbons; the concentration changes frequently, ranging from 100 to 90,000mg / l ;The flow rate is small and intermittent, and its variation range is 10~10000m 3 ,Specifically:

[0017] When the crane tube starts to work, the booster fan set in the system induces air, and the oil and gas first enter the buffer tank to maintain the buffer tank in a slight negative pressure state. Pressure is adjusted. After the device starts, adjust the oil and gas intake according to the total pipeline pressure value. After the mixed gas is boosted to the working pressure by the compressor, the fan ...

Embodiment 2

[0021] This embodiment is a device for recovering active components of multi-component, high-concentration, low-flow, intermittent organic waste gas, such as figure 1As shown, it includes a buffer tank 1, a fan 2, a primary condenser 3, a secondary condenser 4, a tertiary condenser 5, a gas-liquid separation tank 6, a first adsorption tower 7, a second adsorption tower 8, and a third adsorption tower Tower 9, vacuum pump 11, oil storage tank 13 and waste oil pump 14; buffer tank 1 is equipped with organic waste gas inlet, primary condenser 3 is connected with buffer tank 1 organic waste gas outlet through fan 2, primary condenser 3, and secondary condenser 4 and the third-stage condenser 5 are connected in sequence and then connected to the gas-liquid inlet of the gas-liquid separation tank 6, the liquid outlet of the gas-liquid separation tank 6 is connected to the oil storage tank 13, and the gas outlet of the gas-liquid separation tank 6 is connected to the primary condenser...

Abstract

The invention discloses a method for recycling effective ingredients of multi-component high-concentration small-flow intermittent organic waste gas. A concentration method and a pressure swing adsorption method are adopted, primary isolation and purification are carried out on the organic waste gas through the concentration technology, and concentrated waste gas is adsorbed through the pressure swing adsorption technology. An adsorption tank recycles multi-component organic gas by containing adsorbents in a mixed mode, so that the content of non-methane hydrocarbon in purified exhaust gas meets prescribed emission requirements. The device and method are mainly used for recycling the effective ingredients of the multi-component high-concentration small-flow intermittent organic waste gas, the low-pressure concentration technology and the adsorption technology are combined, and the energy consumption is low; the combined technology can be optimized according to medium characteristics, and the processed exhaust gas can meet the new emission standard requirements in China.

Description

technical field [0001] The invention belongs to the technical field of gas recovery and treatment, and relates to an organic waste gas recovery and treatment device, in particular to a device and method for recovering multi-component, high-concentration, small-flow, intermittent organic waste gas active components. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, hereinafter referred to as VOCs) are the most common pollutants emitted by industries such as petrochemical, pharmaceutical, printing, shoemaking, and spray painting. With the development of industry and the improvement of people's living standards, the emission of VOCs is increasing day by day, and has the characteristics of wide range and large emission. Most of these organic substances are toxic and can participate in photochemical reactions to form photochemical smog, which is an important condition for the formation of secondary particulate organic substances in the atmosphe...
