Description

Structurally Improved Natural Gas Tank

technical field

The utility model belongs to the technical field of natural gas collection and distribution devices, and in particular relates to a structurally improved natural gas collection tank.

Background technique

The natural gas collection tank mentioned above is also called a natural gas collection tank, or even a natural gas manifold. It is mainly used in a natural gas transfer station. Its function is to redistribute the natural gas introduced by the natural gas pipeline, specifically by The diversion branch pipe is used to divert the flow, and the diversion branch pipe is introduced into the natural gas filter for filtration, and then filtered out by the natural gas filter for use.

There is no lack of technical information about natural gas filters in the published Chinese patent documents, such as CN2513654Y (natural gas filter), CN2621795Y (multifunctional natural gas filter), CN2743014Y (quick opening pipeline filter), CN2787288Y (natural gas precision filter) . However, the reason why the technical information about the natural gas sink tank has not been seen in the patent and non-patent literature disclosed so far is that the structure of the natural gas sink tank is objectively relatively simple, and the industry believes that it has not been used in actual use. The technical problems caused by the structure itself that affect the diversion of the branch pipe and the connection with the natural gas pipeline are found.

The industry also generally believes that the reason why the natural gas transfer station is located as far away as possible from the living areas of urban and rural residents is because of safety considerations, such as leakage, fire and other situations, which can reduce the damage to people's lives and properties. Degree. However, it cannot be set at a place that is too far away from the living and residential areas of urban and rural residents, because the farther away from the living and residential areas of urban and rural residents, it means that the pipeline will be lengthy, which will increase the cost of pipeline facilities on the one hand, and increase the daily management on the other hand. Nursing workload and costs. Therefore, a reasonable balance point is usually found among the aforementioned factors, that is, it is necessary to meet the specified distance requirements, take into account safety factors, and also consider pipeline facility investment factors.

However, the actual situation is that even if the natural gas transfer station is set up to meet the requirements of a safe distance away from the living quarters of urban and rural residents, it still encounters strong opposition from nearby residents. Nuisance noise will be generated. The current solution can only avoid and set up stations to reduce the degree of noise disturbing the people. However, on the one hand, this method of dealing with the superficial rather than the root cause is not enough to save the cost of the aforementioned pipeline network facilities and management and maintenance costs; on the other hand, the noise nuisance is only reduced rather than eradicated.

The applicant analyzed the structure of the natural gas sink tank shown in Figure 3 in the prior art. The branch pipe interface 2 connected to the tank cavity 11. As shown in Figure 3, the branch pipe interface 2 is fixed to the tank body 1 by welding at the position corresponding to the branch pipe interface provided on the tank body 1. connected, and the air inlet of the branch branch pipe of the branch branch pipe interface 2 is in a 90° positional relationship with the tank wall of the collection tank body 1. Therefore, due to the large flow resistance of the natural gas flowing from the tank cavity 11 to the branch branch pipe interface 2, a whistling sound (also called a whistling sound) that is enough to make people irritated and even creepy will be generated.

Undoubtedly, if the above-mentioned whistling noise can be eliminated, the natural gas transfer station can be set up at a safe distance, regardless of the factors that disturb the residents, and at the same time, the investment in pipeline network facilities and the cost of daily maintenance can be saved . As mentioned above, in view of the revelation that the technical problem can be solved in the Chinese and foreign patents and non-patent literatures disclosed so far, the applicant has made a positive and beneficial design, and finally formed the technical solution to be introduced below, And under the adoption of confidentiality measures, it has been proved to be feasible by computer simulation.
