Description

Technical Field

[0001] The utility model relates to a filter element fixing device in a multi-tube filter element filter, belonging to mechanical equipment. Background Art

[0002] In the current petrochemical industry, filter separators are a widely used type of mechanical equipment. The filter separator uses a filter separation filter element as a separation element, which is mainly used to remove solid impurities and droplets with smaller particle sizes entrained in natural gas to prevent solid particles from entering the device, which affects the normal operation of the mechanical equipment and wears or blocks the pipes, which is not conducive to the improvement of production efficiency and level. The existing multi-tube filter element filter generally adopts a tie rod fixing structure. In order to prevent the medium from directly flushing the filter element, the air inlet is arranged in front of the filter element structure, which will cause the equipment cylinder to be too long. Under the same process conditions, it will increase costs. In this structure, the gas directly flushes the positioning tube, and there is no need to deliberately increase the length of the cylinder to solve the problem that the gas cannot directly flush the filter element.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1a-1b As shown, a filter element fixing device in a multi-tube filter element filter is installed in the barrel 2 of the multi-tube filter element filter. A vertical partition 5, a horizontal support tube 4 and a horizontal filter element 3 are arranged in the barrel 2. The support tube 4 is coaxial with the filter element 3. A vertical flat steel 10 is welded to the inner side of the support tube 4 near one end of the filter element 3. One end of the horizontal flat steel 11 is welded to the vertical flat steel 10, and the other end extends out of the support tube 4 along the axial direction and is welded to one end of the Z-shaped web 13; the Z-shaped web 13 is arranged in the filter element 3 along the axial direction of the filter element 3, and the other end of the Z-shaped web 13 is connected to the fixing plate 18 in the barrel 2; one end of the support tube 4 is welded to the filter element 3 through the joint 12, and the other end is welded to the partition 5; one end of the filter element 3 is welded to the joint 12, and the other end is connected to the fixing plate 18.
