Embodiment Construction

[0029] First, see image 3 As shown, the first embodiment of the present invention is to introduce the waste gas to be purified containing organic solvents produced in the process into an activated carbon adsorption and desorption device 10, so as to perform adsorption and concentration desorption of the organic solvents in the waste gas to be purified. And this activated carbon adsorption-desorption device 10 can be activated carbon fluidized concentrator or fixed bed type concentrator; The carbon adsorption and desorption device 10 concentrates and desorbs the organic solvent, and carries out the purification treatment of incinerator incineration or condenser recovery; in addition, a heat exchanger 30 for heating is set at the upstream end of the activated carbon adsorption and desorption device 10, In order to moderately heat the waste gas to be purified which is introduced into the activated carbon adsorption and desorption device 10, it can be clearly seen from the hygrom...

Abstract

The invention relates to an organic solvent purifying device. According to the device, organic solvent-containing waste gas requiring purifying is introduced to an active carbon adsorption and desorption device, wherein the waste gas requiring purifying is generated during a process; a purifying device is arranged on the downstream end of the active carbon adsorption and desorption device; a heat exchanger for heating is arranged on the upstream end of the active carbon adsorption and desorption device. According to the present invention, the purifying effect of the device of the present invention is stable and is not affected by the weather, the service life of the active carbon can be prolonged, and the energy can be saved.

Description

technical field [0001] The invention relates to a waste gas to be purified containing organic solvents produced in a manufacturing process. Firstly, the particulates in the waste gas flow are filtered out and dehumidified by ice water, and then moderately heated by a heat exchanger, and then adsorbed and desorbed by activated carbon. The design of the adsorption procedure is carried out, especially relating to an organic solvent purification device. Background technique [0002] Organic solvents, which are widely used in life and production, easily volatilize into gases at room temperature, so they are also called Volatile Organic Compounds (VOCs), and most VOCs are toxic to the human body and must be disposed of; however, For the VOCs waste gas produced by the volatilization of the process (such as the spraying process), it is usually as follows figure 1 As shown, an activated carbon adsorption and desorption device 10 is used to perform adsorption, concentration and desor...
