Embodiment Construction
[0022] figure 1 The process flow chart of the purification treatment method of rubber fume mixed with peculiar smell waste gas of the present invention is given, and the waste gas of rubber fume collected on site is processed through three processes in sequence:
[0023] Separation: Pass the rubber smoke and dust mixed with peculiar smell exhaust gas into the separation box, spray the solution water containing NaOH in the reverse direction, and use self-circulation spray to make the rubber smoke oil float on the water surface, flow into the waste oil recovery tank together with the liquid water for recovery, and the dust is recovered by Gravity settles to the bottom of the sink for recycling to the dust bin.
[0024] Decomposition: After the separation, the residual harmful gas is passed into the decomposition box, and the mixed solution containing NaOH is continuously sprayed to decompose the sulfide mainly sulfur dioxide, and react to form sodium sulfite soluble in water. T...

The invention discloses a purification treatment method and device of mixed and smelly rubber smoke exhaust gas. The mixed and smelly rubber smoke exhaust gas is processed by the steps of separation, decomposition and purification in turn, wherein in the separation step, the physical spraying method realizes the separation and collection of rubber smoke oil and dust; in the decomposition step, a solution containing NaOH is used to decompose sulfide mainly containing sulfur dioxide and generate water-soluble sodium sulfate through a reaction; and an activated carbon absorption cotton adsorption device is used for purification, thus effectively removing the contained dust, gelled fuel, sulfide and volatile organic compounds (VOCs) and realizing purification treatment. The purifying rates of sulfur dioxide, hydrogen sulfide, hydroxide and non-methane hydrocarbon (NMHC) and the like are up to above 99% and reach the national discharge standard (GB16297-1996), threreby effectively protecting the physical and mental health of workers and the atmospheric environment surrounding the factory.
Description
technical field [0001] The invention relates to a purification treatment technology for mixed odor waste gas such as rubber smoke and dust, in particular to a method and a device for treating rubber smoke mixed odor waste gas produced in rubber refining, rubber product manufacturing and reclaimed rubber production processes. Background technique [0002] The rubber industry is one of the important industries related to the national economy, national defense industry and people's life. With the rapid development of the automobile industry, my country's tire and rubber product industries are also developing rapidly. A large amount of organic solvents and additives are used in the production of rubber products, which contain many toxic chemical substances, which can be discharged into the environment through water, gas, solid waste, etc., causing immediate or potential cumulative damage to human health and the environment. influences. [0003] Especially during the high-temper...
