CN204892154U - Cyclone flowing back pipeline - Google Patents

Abstract

The utility model provides a cyclone flowing back pipeline at the other slagging valve that connects in cyclone leakage fluid dram and fluid -discharge tube junction, adds pressure balance pipe at fluid -discharge tube U -shaped water seal section top to set up an observation hole at the fluid -discharge tube afterbody. The utility model discloses accessible slagging valve is regularly discharged and is stored up the solid dielectric in the cyclone bottom, and prevent the jam of fluid -discharge tube and the doctor solution that from this leads to blocks up gas piping's problem, and avoid pressure lifting behind the air -blower and the coke oven that causes diffuses. Simultaneously, through pressure balance pipe's the effect of diffusing, eliminate the siphonage of fluid -discharge tube U -shaped water seal section, guaranteed the effective height of water seal.

Description

A kind of cyclone separator Drainage pipe

Technical field

The utility model belongs to chemical pipeline technical field, particularly relates to the Drainage pipe of cyclone separator after a kind of desulfurizing tower.

Background technology

After the desulfurizing tower of chemical plant, cyclone separator removes in coal gas the separation equipment carrying doctor solution secretly, and isolated doctor solution is discharged by the Drainage pipe connected bottom cyclone separator.But because carrying a large amount of solid bits in doctor solution secretly, easily blocking discharging tube and and then cause the blocking of gas piping, and once gas piping blocking will cause air blast after pressure rising and cause coke oven emission.Meanwhile, because the water seal of discharging tube " U " shape is easily forming siphonage in exterior liquid process, cause " U " shape water seal effective depth inadequate, cause coal gas to puncture, harm site safety.

Summary of the invention

The utility model aims to provide one and discharging tube can be avoided to block, and eliminates discharging tube " U " shape water seal siphonage, ensures the cyclone separator Drainage pipe of water seal height.

For reaching this object, the utility model takes following technical solution:

A kind of cyclone separator Drainage pipe, is characterized in that, connects a slagging valve, set up pressure-equalizing pipe, and offer a peep hole at discharging tube afterbody at discharging tube U-shaped aqua seal section top at cyclone separator leakage fluid dram and side, discharging tube junction.

Good effect of the present utility model is:

The utility model regularly discharges the solid dielectric accumulated in bottom cyclone separator by slagging valve, the problem of doctor solution blocking gas piping preventing the blocking of discharging tube and cause thus, avoids pressure after air blast to raise and the coke oven emission that causes.Meanwhile, diffuse effect by pressure-equalizing pipe, eliminate the siphonage of discharging tube U-shaped aqua seal section, ensure that the effective depth of water seal.

Accompanying drawing explanation

Fig. 1 is cyclone separator Drainage pipe structural representation.

In figure: discharging tube 1, slagging valve 2, cyclone separator 3, U-shaped aqua seal section 4, pressure-equalizing pipe 5, peep hole 6.

Detailed description of the invention

As seen from Figure 1, the utility model cyclone separator Drainage pipe, one is connect a slagging valve 2, regularly to discharge the solid dielectric accumulated in bottom cyclone separator 3 on the side, junction of cyclone separator 3 lower end leakage fluid dram and discharging tube 1.Two is set up a pressure-equalizing pipe 5 at the top of the U-shaped aqua seal section 4 of discharging tube 1, by diffusing of pressure-equalizing pipe 5, eliminates the siphonage of discharging tube 1U shape aqua seal section 4, ensure that the effective depth of water seal.Three is offered a peep hole 6 at the afterbody of discharging tube 1, for checking the discharge opeing situation of cyclone separator 3.

Claims (1)

1. a cyclone separator Drainage pipe, is characterized in that, connects a slagging valve, set up pressure-equalizing pipe, and offer peep hole at discharging tube afterbody at discharging tube U-shaped aqua seal section top at cyclone separator leakage fluid dram and side, discharging tube junction.
