Description

TECHNICAL FIELD

[0001] The utility model relates to a gasification furnace production system field, concretely relates to a gasification furnace goes torch system crude coal gas pipeline cut -out valve filter joint. BACKGROUND

[0002] The crude coal gas of gasification furnace out waste pot pipe course enters crude coal gas gas -liquid separator, utilizes cyclone separation principle to separate the liquid entrained in crude coal gas airflow, and the liquid enters the liquid level below waste pot collecting tank through the communication pipe of waste pot bottom and waste pot.

[0003] The venting pipeline is arranged on the crude coal gas pipeline, the pressure regulating valve and the cut -out valve are arranged on the pipeline, and the venting pipeline is used for venting in normal driving, hot standby or emergency shutdown state and gradually discharging to the torch system.

[0004] At present, the cut -out valve adopts the metal hard -seal ball valve to control the torch gas venting, due to the H2, CO and solid medium in the medium, the valve inner part appears jam, the ball surface spray layer appears the washing phenomenon, thereby the valve internal leakage problem appears, and the crude coal gas venting pipeline of torch system is unstable.

[0005] Therefore, a filter joint capable of filtering and saving cost is needed. UTILITY MODEL CONTENTS

[0006] The utility model discloses a gasification furnace goes torch system crude coal gas pipeline cut -out valve filter joint.

[0007] The utility model discloses the following technical scheme implementation:

[0008] A gasification furnace goes torch system crude coal gas pipeline cut -out valve filter joint, including the connecting pipe, the baffle is fixedly installed in the connecting pipe, two groups of fixed cylinders are fixedly connected on the connecting pipe, and each group of fixed cylinders is two, and the filter pipe is inserted in each group of fixed cylinders, and the filter pipe is U-shaped, and the filter screen is fixedly installed in the filter pipe, two cavities are arranged in the fixed cylinder, and the T-shaped slide rod is slidably connected in each cavity, the spring is sleeved on each T-shaped slide rod, and one end of each T-shaped slide rod extends into the connecting pipe and is slidably connected with it, and the top plate is fixedly connected between the one end of the corresponding two T-shaped slide rods, the plugging plate is fixedly installed on the top plate, the T-shaped jacks are fixedly connected between the inner wall of each port of the filter pipe, and one end of each T-shaped jack is arranged in close contact with the corresponding plugging plate.

[0009] Preferably, the locking ring is fixedly installed on the fixed cylinder, two sealing rings are fixedly installed on each filter pipe, each sealing ring extends into the corresponding locking ring and is arranged in close contact with it, and the locking screw is screwed on the outer wall of the locking ring.

[0010] The advantages of this invention are: the device has two filter pipes and a baffle, which allows filtration to be performed without affecting the flow of the medium. When cleaning impurities in the pipes, the corresponding pipe can be pulled out directly. The operation is simple and convenient, and the cost is low, which can greatly save costs and indirectly improve the service life of the shut-off valve. Attached image description:

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] In the diagram: 1. Connecting pipe; 2. Partition plate; 3. Fixing cylinder; 4. Cavity; 5. T-shaped slide bar; 6. Spring; 7. Top plate; 8. Sealing plate; 9. Filter pipe; 10. Filter screen; 11. T-shaped top rod; 12. Sealing ring; 13. Locking ring. Detailed implementation method:

[0013] like Figure 1 As shown, a filter connector for a raw gas pipeline shut-off valve in a gasifier flare system includes a connecting pipe 1, a baffle plate 2 fixedly installed inside the connecting pipe 1, two sets of fixed cylinders 3 fixedly connected to the connecting pipe 1 (each set consisting of two cylinders), and a filter pipe 9 inserted into each set of fixed cylinders 3. The filter pipe 9 is U-shaped and has a filter screen 10 fixedly installed inside. Two cavities 4 are provided inside the fixed cylinder 3, and a T-shaped slide rod 5 is slidably connected to each cavity 4. A spring 6 is sleeved on each T-shaped slide rod 5. One end of each T-shaped slide rod 5 extends into and slidably connects to the connecting pipe 1. A top plate 7 is fixedly connected between the ends of corresponding two T-shaped slide rods 5, and a sealing plate 8 is fixedly installed on the top plate 7. Each port of the filter pipe 9... T-shaped push rods 11 are fixedly connected between the inner walls of each valve. One end of each T-shaped push rod 11 is fitted with a corresponding sealing plate 8. During normal operation, due to the sealing of the partition plate 2, the medium flows along the two filter pipes 9, thereby using the filter screen 10 for filtration, which indirectly improves the service life of the shut-off valve. After long-term operation, a lot of impurities accumulate at the filter screen 10, which needs to be cleaned. At this time, the filter pipe 9 to be cleaned is pulled out directly. As the filter pipe 9 is pulled out, the elastic force of the spring 6 is released, which causes the sealing plate 8 to engage with the water inlet end of the corresponding fixed cylinder 3, thereby forming a blockage. The operation is simple and convenient, and there is no need to stop the machine, which greatly improves the cleaning efficiency.

[0014] A locking ring 13 is fixedly installed on the fixed cylinder 3, and two sealing rings 12 are fixedly installed on each filter tube 9. Each sealing ring 12 extends into the corresponding locking ring 13 and fits tightly with it. A locking screw is screwed onto the outer wall of the locking ring 13. The locking screw plays a fixing role to fix the filter tube 9 and keep it running stably. During the cleaning process, although the sealing plate 8 blocks the corresponding fixed cylinder 3, leakage may still occur in different situations. At this time, a cylinder cover is screwed onto the outside of the sealing ring 12 to maintain the seal and ensure that there is enough time to clean the filter tube 9 and the internal filter screen 10.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
