Abstract

The utility model discloses a balancing agent filter, which comprises a balancing agent filter tube. The front end of the balancing agent filter tube is communicated with a reactivator output tube and the rear end of the balancing agent filter tube is communicated with the input tube of a balancing agent tank. A filter panel is arranged between the balancing agent filter tube and the input tube. The middle and rear portion of the balancing agent filter tube is communicated with a fragment settling tube extending downwardly. The lower port of the fragment settling tube can be connected with a fan. The middle and upper portion of the fragment settling tube is communicated with a fragment emptying pipe extending in an inclined downward direction. The fragment emptying pipe is provided with an emptying valve and the lower portion of the fragment settling tube is provided with a blowing valve. A blowing distribution plate is arranged between the communicated parts of the blowing valve and the fragment emptying pipe in the fragment settling tube. The blowing distribution plate is closely provided with air through holes. A blowing sieve plate positioned below the blowing valve is arranged in the fragment settling tube. The blowing sieve plate is closely provided with sieve apertures. Due to the adoption of the balancing agent filter, lining fragments in a balancing agent can be removed, while the delivery speed of the balancing agent is ensured.

Description

A kind of poising agent filter

Technical field

The utility model relates to a kind of poising agent filter.

Background technology

In the catalytic cracking reaction process, the powder catalyst of exporting from regenerator is referred to as poising agent, and poising agent is from the efferent duct output of regenerator, and the input pipe of self-balancing agent jar gets into the poising agent jar, between efferent duct and the input pipe sieve plate is housed.Unload in the agent process at poising agent, because the influence of the lining fragment that comes off in the regenerator, poising agent is packed into and is caused sieve plate to stop up easily when promptly going into operation the dress agent in the poising agent jar, has a strong impact on the progress that goes into operation.

The utility model content

The technical problem that the utility model will solve provides a kind of poising agent filter that can remove lining fragment in the poising agent.

For solving the problems of the technologies described above; The poising agent filter that is provided; Its design feature is that this filter comprises the poising agent screen pipe that front end is communicated with the regenerator efferent duct, the rear end is communicated with the input pipe of poising agent jar; Between poising agent screen pipe and the input pipe filter is housed, the postmedian of poising agent screen pipe is communicated with down to be stretched and fragment sedimentation pipe that lower port can link to each other with blower fan, and the middle and upper part of fragment sedimentation pipe is communicated with the fragment blow-down pipe of tiltedly stretching down; The emptying valve is housed on the fragment blow-down pipe; The blowing valve is equipped with in the bottom of fragment sedimentation pipe, is equipped with in the fragment sedimentation pipe at the blowing valve to be communicated with the blowing distribution grid between the place with the fragment blow-down pipe, is densely covered with the wind hole on the blowing distribution grid.

The blowing sieve plate that is positioned at blowing valve below is housed in the said fragment sedimentation pipe, is densely covered with sieve aperture on the blowing sieve plate.

After adopting said structure; The lower port of fragment sedimentation pipe is linked to each other with blower fan, poising agent from efferent duct through the poising agent screen pipe in the input pipe course of conveying, under the effect of blowing; Catalyst further separates with the lining fragment; The lining fragment is deposited in the fragment sedimentation pipe under the effect of gravity, and slides along the fragment blow-down pipe, also plays the effect of conveying when blowing separates the poising agent that settles down with the lining fragment.

In sum, the utlity model has the advantage that to remove lining fragment in the poising agent, and can guarantee the transporting velocity of poising agent.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of blowing distribution grid;

Fig. 3 is the vertical view of blowing sieve plate.

The specific embodiment

Poising agent filter as shown in Figure 1; It comprises the poising agent screen pipe 1 that front end is communicated with regenerator efferent duct 8, the rear end is communicated with the input pipe 9 of poising agent jar; Between poising agent screen pipe 1 and the input pipe 9 filter 10 is housed; Poising agent screen pipe 1 and the structure that the connected mode of efferent duct 8 and input pipe 9 can adopt flange to be connected also can adopt the socket weld connection structure connecting, and poising agent screen pipe 1 level is installed.The postmedian of poising agent screen pipe 1 is communicated with down to be stretched and fragment sedimentation pipe 2 that lower port can link to each other with blower fan; The middle and upper part of fragment sedimentation pipe 2 is communicated with the fragment blow-down pipe of tiltedly stretching down 3; Emptying valve 4 is housed on the fragment blow-down pipe 3, and blowing valve 5 is equipped with in the bottom of fragment sedimentation pipe 2.As depicted in figs. 1 and 2; Be equipped with in the fragment sedimentation pipe 2 at blowing valve 5 and be communicated with the blowing distribution grid 6 between the place with fragment blow-down pipe 3; Be densely covered with wind hole 7 on the blowing distribution grid 6, blowing distribution grid 6 can play all even effect that prevents lining fragment blocking pipeline of the wind of cooking a meal; As shown in figures 1 and 3, the blowing sieve plate 11 that is positioned at blowing valve 5 belows is housed in the fragment sedimentation pipe 2, be densely covered with sieve aperture 12 on the blowing sieve plate 11, sieve aperture 12 plays blowing is acted on more uniformly.

The utility model will comprise that the front end of poising agent screen pipe 1 is communicated with regenerator efferent duct 8, the rear end is communicated with the input pipe 9 of poising agent jar in use, and the lower port of fragment sedimentation pipe 2 is connected with the discharge pipe of blower fan; Open blowing valve 5; When poising agent during from 8 outputs of the efferent duct of regenerator, the lining fragment realizes that in the middle leading portion of poising agent screen pipe 1 preliminary sedimentation falls, and blowing is from the middle and upper part of sieve aperture 12 through wind holes 7 entering fragment sedimentation pipes 2; Blowing blows afloat pulverous poising agent; The lining fragment can fall to sliding in the fragment blow-down pipe 3 under the effect of gravity, regularly opens emptying valve 4 emptying of lining fragment is got final product; Do not influence the agent process of unloading of poising agent when opening emptying valve 4, thereby can realize continued operation.
