Problems solved by technology

The catalytic reaction method is mainly used for the purification of high-temperature, high-concentration, and continuous emission of organic waste gas. However, due to the complex composition of chemical waste gas, the organic matter in chemical waste gas cannot be completely removed by catalytic reaction methods.
The direct catalytic reaction method is suitable for the purification of high-temperature and high-concentration organic waste gas, and can recover heat, but the direct catalytic reaction method consumes a lot of energy and needs to use heavy oil and natural gas as preheating energy, and the cost is relatively high
[0003] At present, there is no device for simultaneous treatment of waste oil, waste gas and solid chemical waste

Abstract

The invention belongs to the technical field of chemical waste treatment, and particularly relates to a chemical waste treatment device and treatment process. The chemical waste treatment device comprises a reactor, wherein a first material gun, a second material gun and a solid material conveyor are arranged at the side part of the reactor; the reactor, a cyclone separator, a front heat exchanger, a rear heat exchanger, an energy-saving heat exchanger, an air preheater, a dust collector, an exhaust fan and a chimney are connected in sequence; a high-temperature fan is connected with the front heat exchanger and the rear heat exchanger; the high-temperature fan, a flue gas mixer and the reactor are connected in sequence; the flue gas mixer is connected with the air preheater; the energy-saving heat exchanger is connected with the reactor; a secondary fan is connected with the air preheater; and a primary fan is connected with the reactor. According to the chemical waste treatment device and treatment process, waste oil, waste gas and solid chemical waste enter into the reactor at the same time for treatment. The waste gas can serve as a preheating energy source, but heavy oil and natural gas do not need to serve as preheating energy sources, so that the cost is relatively low.

Description

technical field [0001] The invention belongs to the technical field of chemical waste treatment, and in particular relates to a chemical waste treatment device and a treatment process. Background technique [0002] In the production process of chemical industry and other industries, a large amount of waste oil, waste gas and solid chemical waste will be produced, which are harmful to human body and cause great damage to the environment. At present, the main method of treating waste oil is to make secondary use of waste oil refining, or obtain gasoline, diesel oil, etc. as fuel, but this method is expensive and cannot be promoted; domestic waste oil is also directly burned as fuel, but the The reaction of the equipment is insufficient, the heat utilization rate is low, and a lot of toxic gases such as sulfur dioxide and carbon monoxide are produced after the reaction. These toxic gases are directly discharged without purification treatment, causing environmental pollution. T...
