Embodiment 1

[0020] The cyclone separator material leg of the present invention is as figure 1 As shown, it includes the material leg 5, the first wing valve and the second wing valve, the upper part of the material leg is connected with the cyclone separator, the first wing valve and the second wing valve are connected at the bottom of the material leg, the first wing valve and the second The wing valves are arranged side by side. The first wing valve is composed of No. 1 valve body 3, No. 1 hanging post 7, No. 1 lifting ring 8, and No. 1 valve plate 1. The second wing valve is composed of No. 2 valve body 4, No. 2 hanging post 9, and No. 2 hanging ring 10. , The No. 2 valve plate is composed of 2, and the No. 1 davit and the No. 2 davit are welded and fixed on the valve body. The No. 1 valve plate is positioned and installed on the No. 1 valve body through the No. 1 lifting ring, and the No. 2 valve plate is positioned and installed on the No. 2 valve body through the No. 2 lifting ring...

Embodiment 2

[0024] Another embodiment of the present invention is as figure 2 As shown, it includes the material leg 5, the first wing valve and the second wing valve, the upper part of the material leg is connected with the cyclone separator, the first wing valve and the second wing are connected to the lower part of the material leg, the first wing valve and the second wing The valves are arranged side by side at equal heights. A partition 6 is provided at the lower part of the material leg 5 to separate the partition from the discharge inlets of the first wing valve and the second wing valve. The height H of the partition 6 is 1.0-2.0 times the diameter D of the dipleg 5 . The diameter d of No. 1 valve body and No. 2 valve body is 0.4 times of the diameter D of the material leg. The weight of No. 1 valve plate is 0.5 times of that of No. 2 valve plate. The height distance L between the first wing valve and the second wing valve is 2.5 times of the diameter D of the dipleg.

Abstract

The invention relates to a material leg of a cyclone separator, which comprises a material leg 5, and the upper part of the material leg is connected with the cyclone separator. The lower part of the dipping leg is connected with the first wing valve and the second wing valve, and the first wing valve and the second wing valve are arranged side by side at equal heights or arranged side by side at heights. The two wing valves are respectively composed of a valve body, a hanging post, a lifting ring and a valve plate. The hanging post is welded and fixed on the valve body, and the valve plate is positioned and installed on the valve body through the hanging ring. The diameter d of the valve body is 0.3-0.6 times of the diameter D of the material leg. In the present invention, two wing valves are arranged at the lower part of the material leg, the two wing valves are arranged side by side or equal in height, and the weights of the two valve plates are equal or unequal, so that the separation effect of the cyclone separator and the efficiency of the material leg are improved. The stability of discharge can adapt to the operating conditions where the mass flow rate of particles in the material leg changes greatly, and can prevent the erosion and wear of the wing valve plate at the same time.

Description

technical field [0001] The invention belongs to the technical field of gas-solid separation equipment, and relates to a material leg of a cyclone separator, in particular to a material leg of a cyclone separator with a double-wing valve structure. Background technique [0002] The cyclone separator is one of the important equipment of the petroleum catalytic cracking unit. Usually, the lower part of the cyclone separator is connected to the material leg to form a downward passage for the particles, and a wing valve is set at the bottom of the material leg, so the material leg and the wing valve constitute a cyclone separation The discharge system of the device. The function of the wing valve is to stabilize the concentration and storage of catalyst in the material leg, to balance the negative pressure difference between the inside of the material leg and the discharge space outside the wing valve, to have one-way discharge and to prevent the gas from entering the material le...
