Description

TECHNICAL FIELD

[0001] The utility model belongs to ozone generation technical field, concretely relates to a container type ozone generator. BACKGROUND

[0002] With the rapid development of the electric power industry, the demand for coal power unit peak shaving is increasing, and the control of flue gas emission standards is becoming more and more strict. Under this background, ozone, as a kind of efficient oxidant, has shown significant advantages in the oxidation removal process of NO (nitrogen oxide) in flue gas, and has been widely used in the field of flue gas desulfurization and denitrification. As the core equipment of this technology, the composition of ozone generator usually includes ozone generator, compressed air purification device, internal circulating cooling water pump, heat exchanger, electric control box, power cabinet and a series of key components such as pipeline, valve and instrument.

[0003] In the conventional ozone application project, in order to ensure the efficient operation of the equipment and facilitate maintenance, a special ozone generator plant will be set up, and all components will be reasonably arranged in the plant. The advantage of this arrangement is that the plant area is sufficient, which can ensure the reasonable layout of the equipment and the convenient maintenance channel. However, in actual application, due to the planning limitation at the beginning of construction, some transformation projects cannot reserve enough space for the construction of ozone generator plant, which brings great challenge to the implementation of the project. In order to solve the above problems, a container type ozone generator is proposed, which integrates all components of ozone generator in a container, realizing the advantages of simple overall installation, flexible site arrangement, no need to build a separate plant, less site construction work and low system investment cost. However, this scheme also exposes some deficiencies in actual application. For example, the equipment is arranged scatteredly in the container, which cannot realize effective functional partition, resulting in complicated equipment installation process and poor working environment for operation personnel. In addition, the electric control equipment and the internal circulating cooling water pump, pipeline and other key components are in the same container, once the water leakage accident occurs, it is easy to cause the electric control equipment to be damp, short circuit, corrosion and structure damage, thereby seriously affecting the stable operation of the equipment. Especially for large ozone generator, the integration of all components in a single container will result in large volume and heavy weight of the single container, which will cause difficulties in transportation, hoisting and site arrangement. The above container type ozone generator is usually suitable for small and medium-sized ozone generators with ozone rated output not more than 40 kg / h, which is difficult to meet the demand of ozone quantity in the field of flue gas desulfurization and denitrification.

[0004] In summary, the container type ozone generator in the prior art solves the problem of site limitation to some extent, but there are still many deficiencies in equipment arrangement, operation and maintenance, safety and applicability, which need to be further improved and optimized. The utility model discloses a container type ozone generator, which is characterized by the following technical scheme.
