As an important part of the “15th” national major technological equipment development program, the large-scale fertilizer equipment research and development project relies on Shandong Hualu Hengsheng Chemical Industry Co., Ltd. 300,000 tons of synthetic ammonia and 600,000 tons of urea technological transformation projects, since November 2004 construction. After completing and producing qualified products, it has been safely and smoothly operated for more than 20 months. On September 6, the project passed the acceptance of an acceptance committee composed of experts from the China Petroleum and Chemical Industry Association and China Machinery Industry Federation.

The project includes 19 topics for development of process software packages, development of key equipment for coal-water slurry gasification, development of key equipment for synthesis gas purification, development of key equipment for ammonia synthesis, and development of key equipment for urea plants. Calculated according to the total investment, the localization rate reached 93.8%. The total investment of the project is only nearly 1.4 billion yuan, less than half of the imported devices.

The acceptance committee believes that this project has developed the core technology and complete sets of equipment for large chemical fertilizers with independent intellectual property rights, and achieved the first set of autogenous 300,000 tons of ammonia synthesis equipment with coal as raw material, rewriting the history of large fertilizer installation relying on introduction. In order to promote the adjustment of raw material structure in the nitrogen fertilizer industry and technological transformation of small and medium-sized nitrogenous fertilizer companies, reduce energy consumption, protect the environment, and improve industry technology and equipment levels, demonstration projects and technical support are provided, and the development of related industries is also promoted and promoted.

It is understood that from the 1970s when China introduced 13 sets of large-scale chemical fertilizers, localization of large-scale fertilizer installations began. However, localization of complete installations has not been realized. This time, Hualu Hengsheng developed the technology software package with independent intellectual property rights, developed key equipment, and formed the integration capability of complete sets of equipment. The overall technology has reached the international advanced level and some technologies have reached the international advanced level. Level. After expansion and transformation, the company has been rolling from a small nitrogen fertilizer company to a large-scale fertilizer production enterprise with an annual production capacity of 1 million tons of urea, and the next step will be to extend and expand the acetic acid product.

Product introduction
1, can be directly installed on the top, side or bottom of the tank, the filter head is exposed outside the tank, the cylinder part is immersed in the tank, thus simplifying the system pipeline, so that the system layout is more compact.
2, equipped with magnets, can filter the oil more than 1 micron ferromagnetic particles,
3, with bypass valve: when the cold oil starts, due to the system liquid temperature is too low, flow pulsation and other factors caused by the filter pressure difference is too large host can not work, and the filter element is blocked by pollutants, the parallel bypass valve at the lower part of the filter cover will automatically open,( 2015730,opening pressure difference is 0.4MPa) to protect the filter element and the system work normally.
4, with a check valve: the filter is placed on the side and bottom of the tank, when replacing the filter, the oil in the tank will not flow out.
5. The flow diffuser is provided. The flow diffuser composed of the lower part of the simplified part can make the return oil flow into the tank smoothly, which is not easy to produce bubbles, reduce the re-entering air, weaken the commotion of deposited pollutants, and can play a coarse filtering role when the bypass valve is opened.
