Description

Frameless natural gas filter element end cover

Technical Field

The utility model relates to an end cover of a skeleton-free natural gas filter element, and belongs to the technical field of skeleton-free natural gas filter elements.

Background

The skeleton-free natural gas filtering filter element: the filter is arranged in a filter separator to remove solid dust with smaller particle size and liquid drops with larger particle size carried in natural gas, and has no built-in metal framework.

End cover: the filter element is arranged at two ends of the filter element, and the filter element is connected with the filter to achieve the fixing and sealing effects in the filter.

The natural gas filtering filter element needs to be replaced regularly, and the replaced filter element has a large amount of dust and condensate oil due to natural gas filtering, so that the natural gas filtering filter element belongs to dangerous waste pollutants, cannot be treated at will and needs to be carried out by a professional dangerous waste recovery company. The two ends of the traditional filter element are end covers made of stainless steel materials and sealed by punch forming end faces, and when hazardous waste is treated, the metal end covers need to be disassembled in advance, so that the treatment difficulty is high, the cost is high, and the waste of metal resources is caused.

The existing natural gas filter element end cover is axially sealed at two ends, and the number of sealing points of the installation and fixing mode is more, namely, the number of leakage risk points is also more. The installation and fixing structure of the filter element end cover can effectively reduce sealing points and reduce leakage risks.

The natural gas filtering filter element is arranged inside a filtering separator in a natural gas long-distance pipeline, is mainly used for removing solid dust impurities and large liquid drops in natural gas, and plays an important role in protecting important equipment such as a compressor, a gas turbine, a flowmeter and the like. After the natural gas filtering filter element is used for a period of time, when the pressure difference is changed, the filter element needs to be changed. Therefore, the natural gas station maintenance personnel need to replace the filter element every year.

The existing natural gas filtering filter element consists of a polymer filtering layer and metal end covers, the end covers are of a structure with through holes at two ends, namely a flat-end sealing form at two ends, and each filter element uses two end covers. The end cover is formed by stamping stainless steel materials, the filter element needs to be replaced after being used for a period of time, the replaced end cover of the filter element cannot be reused, and a large amount of stainless steel resources are wasted every year. Meanwhile, the whole filter element contains the metal end cover, so that the whole filter element cannot be completely combusted during hazardous waste treatment, and the metal end cover needs to be disassembled and removed in advance, so that the treatment difficulty is high. The metal end covers of the same end face sealing form are used for the end covers at the two ends of the existing natural gas filtering filter element, the number of sealing points of the installation and fixing mode is more, and the leakage risk points are more. With the continuous development of economy, the cost of metal materials is continuously increased, and the cost of product materials is increased.

The disadvantages of the prior art are as follows: the filter element end cover is made of stainless steel materials, cost is high, resource waste is caused, the end cover is in an end face sealing mode, sealing points are more in the installation and fixing mode, leakage risks are large, the metal end cover is large in dangerous waste treatment difficulty of the filter element after replacement.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a framework-free natural gas filter element end cover.

A skeleton-free natural gas filter element end cover is characterized in that the upper end cover of a filter element is a blind cover with a handle, the handle is connected with the upper surface of the end cover, the handle is provided with a plurality of support ribs, the center of the lower surface of the end cover is provided with a center hole, the outer side of the center hole is connected with a rib plate, the rib plate is connected with a positioning ring, the outer side of the positioning ring is connected with a skeleton positioning support rib plate, the support rib plate is of a trapezoidal structure, the top end of the support rib plate is provided with a guide angle, the middle part of the support rib plate is provided with a first step, and the inner side of the lower end cover of the filter element is provided with a reinforced guide rib plate, and the inner cavity of the lower end cover of the filter element is provided with the anti-falling triangular rib plate.

An O-shaped sealing ring is arranged in the groove of the O-shaped sealing ring.

The method has the advantages that the method can greatly reduce the difficulty in treating the hazardous waste, effectively reduce the treatment cost and avoid the repeated waste of resources. The end cover is made of modified PP materials, so that the cost is low and resources are saved; the filter element formed by the end cover is quickly installed, and the hazardous waste treatment cost is low; the filter element formed by the end cover has few sealing points and low leakage risk; the end cover is provided with a handle, so that the filter element is convenient to install; the end cover uses the rib plate, so that not only is the functional strength achieved, but also materials can be saved.
