Liquid collection device of ozone and waste gas mixed reactor

Abstract

The invention discloses a liquid collection device of an ozone and waste gas mixing reactor, and belongs to the field of waste gas treatment equipment. The liquid collection device comprises a cavity body, wherein a liquid collection device body is arranged below a gas inlet pipe in the cavity, and comprises a conical tray with a steplike structure and an isolation plate with a through hole in the center; cooling nozzles are arranged on the isolation plate; the isolation plate, the conical tray and a lower end socket are hermitically connected to form a cooling chamber; a cooling medium enters the cooling chamber through a cooling opening connection pipe. The liquid collection device disclosed by the invention is used for collecting condensed fluid generated in a reaction process and supplying the cooling medium into the cavity, so that fluid and granular suspensions which are generated in the cavity can be discharged in time, and the influence on mixing reaction and equipment due to the substances is reduced; meanwhile, the mixed gas is in a low-temperature state, decomposition of ozone is stopped, the probability of explosion is reduced, and the utilization rate of the ozone is increased.

Description

technical field [0001] The invention relates to the field of chemical waste gas treatment equipment, in particular to a liquid collection device for a mixed reactor of ozone and waste gas. Background technique [0002] During the production of chemical products such as phenylethyl alcohol, terpineol, and hydrogenated rosin, the industrial waste gas produced is often foul-smelling gas, which not only pollutes the atmosphere, but also causes direct damage to the human body. The state stipulates that the waste gas discharged from the factory must be Only after the purification reaches the standard can it be discharged to the outside. At present, the treatment of malodorous gas is mainly divided into physical method and chemical method. Physical method includes masking method and dilution diffusion method. Due to its low input cost, simple treatment method and quick effect, it is more suitable A wide range of methods, but because this method aims to alleviate or disperse the ste...

Problems solved by technology

[0008] However, due to the poor stability of ozone, it can be decomposed into oxygen by itself at normal temperature and pressure. Even if it is produced and used now, the utilization rate of ozone is relatively low.

At the same time, ozone will release a large amount of reaction heat during the oxidation process. If the generated reaction heat is not dealt with in time, a vicious circle will be formed, which will further promote the decomposition of ozone, reduce the utilization rate of ozone, and cause an explosion due to high temperature. Danger (during the process of ozone oxidation exhaust gas, the generated sulfur suspended particles, methyl mercaptan and other harmful substances are mixed with air and ozone to form an explosive mixture, which will explode when encountering an open flame or a high temperature, especially when the temperature After exceeding 25 °C, the explosiveness of methyl mercaptan increases with the increase of temperature, and the accident rate is higher)

In addition, according to the above reaction formula, it can be known that the above-mentioned ozone will cause non-gaseous substances such as S to be produced in the exhaust gas during the oxidation reaction process, and these non-gaseous substances will be condensed and precipitated and left in the reactor. If it is not treated in time, it will not only corrode the equipment, but also further increase the explosion probability of the mixed gas, affecting the safe operation of the equipment
