Problems solved by technology
[0004] If the by-products produced by coal-to-natural gas are not stirred due to high viscosity, dust, and water content, the coal dust and moisture will solidify on the surface of the heater, which not only reduces thermal efficiency, but also deposits coal dust at the bottom of the storage tank over time. Cause pipeline blockage and inaccurate measurement, because the storage tank design specification clearly stipulates that 20000m 3 The following small storage tanks should not be equipped with agitators. If the side agitation of the storage tanks is increased through technical transformation and other means, a series of expenses such as equipment costs and post-maintenance will be increased.

Embodiment Construction
[0030] In order to facilitate the understanding of the present invention, the present invention is further described and explained in conjunction with the accompanying drawings and embodiments.
[0031] The present invention provides a system that promotes thermal diffusion inside the tank, such as figure 1 As shown, the by-product material obtained by the gas purification and separation device 100, such as tar, is transferred to the storage tank feed pipe 101a, 101b through the material input pipe 101, and then the material enters the storage tank under the control of the valve. figure 1 Shown is a combination tank consisting of two storage tanks 102a and 102b, the tank feed pipes 101a, 101b are respectively connected to top spare ports 112a, 112b provided at the top of the storage tanks 102a, 102b, And a sleeve pipe is arranged inside the storage tank to lead directly from the top spare port to the bottom of the storage tank (not shown). The materials in the storage tank 10...

The invention provides a system for promoting heat diffusion in storage tanks. The system comprises the storage tanks, a material input pipe, storage tank feeding pipes, storage tank discharging pipes, a pump, a pump discharging pipe, a material output pipe, a tank toppling pipe, a tank toppling feeding pipe, top standby openings and a sleeve. Meanwhile, the invention further provides a method for promoting heat diffusion in the storage tanks by applying the system for promoting heat diffusion in the storage tanks. According to the system and method for promoting heat diffusion in the storage tanks, balanced heating and diffusing of the storage tanks are achieved through circulating flow of materials in the storage tanks, surface solidification of a heater is reduced, the heat efficiency is improved, and the problems that materials in a small-size storage tank are unevenly heated due to the fact that stirring equipment cannot be installed in the small-size storage tank, and heat diffusion is affected due to the fact that the materials with high viscosity and low liquidity are solidified on the surface of the heater are effectively solved.
Description
technical field [0001] The invention relates to the technical field of coal chemical storage tank equipment. Specifically, the present invention relates to a storage tank used in a pressurized gasification process, especially to a storage tank with a volume of 20,000m 3 Systems and methods for promoting thermal diffusion within a storage tank are described below. Background technique [0002] my country's coal-to-natural gas, coal-to-olefins, and coal-to-methanol are booming, and most coal chemical processes use coal gasification to produce syngas and convert it into carbon products. [0003] Lurgi pressurized gasification technology was first developed by Lurgi Company in Germany. Due to its own process characteristics, this technology produces by-products such as oil, tar, naphtha, crude phenol, etc. These by-products contain coal dust, water, etc. Impurities, in order to meet the process requirements of normal material transfer, it is necessary to keep the temperature o...
