Description

Device for ensuring safe external drainage of drainer

Technical Field

The utility model relates to a guarantee device of drainer safety outer drainage.

Background

The steel enterprises respectively generate coke oven gas, blast furnace gas and converter gas in the processes of coking, ironmaking and steelmaking, and the gas is collectively called as artificial gas. A large amount of saturated water exists in the artificial gas, and the saturated water is discharged through a drainer, so that the safe operation of the gas system equipment is ensured. The water drainer has the functions of sealing the gas and draining saturated water separated out from the gas in the pipeline and the equipment. According to the regulation of industrial enterprise gas safety management regulations, condensed water in blast furnace gas and converter gas can overflow to a drainage pipe network in a form of building auxiliary wells. According to the regulation, each drainer connected with the drainage pipe has to repair a secondary well, which requires high investment, space for building the well on site and long construction period. The auxiliary well has the effect that after the drainer breaks down or has a water shortage fault and the coal gas leaks outside, the coal gas cannot flow into the drainage pipe network through the drainage pipe. If this failure occurs, it will be a major accident. The reason is that the mixing of the coal gas and the air can form explosive gas, and the whole drainage pipe network system can be subjected to explosion accidents when exposed to open fire. In addition, the gas has toxicity, which is very easy to cause gas poisoning accidents for pipeline operators.

Disclosure of Invention

An object of the utility model is to provide a guarantee device of drainer safety external drainage, the device can be under the circumstances of guaranteeing safety, and the comdenstion water that appears in blast furnace gas and the converter gas system is discharged into the water pipe network, when guaranteeing that the trouble coal gas that punctures or lack of water appears in the drainer leaks outward, also can not scurry into the water pipe network with the coal gas.

Realize the device of the safe outer drainage of drainer of above-mentioned purpose, including a square basin that welds with 8 mm's steel sheet, basin height 700mm, the centre is equipped with a baffle, the height of baffle is 600mm, the baffle divide into basin I room on left basin and the II rooms on right side with the basin inner space, and I indoor in basin is received to the drain pipe of drainer, and this drain pipe lower extreme mouth of pipe is 200mm apart from the basin bottom, is connecting outer drain pipe in II room bottoms in basin.

The device can discharge the condensed water separated out from the blast furnace gas and the converter gas system into a drainage pipe network under the condition of ensuring safety. When breakdown or water shortage fault gas leakage occurs in the drainer, the gas cannot flow into the drainage pipe network, and the safety of the drainage pipe network is ensured.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

The utility model provides a guarantee device of drainer safety outer drainage, as shown in figure 1, include a square basin that welds with 8 mm's steel sheet, basin height 700mm, the centre is equipped with a baffle 2, the height of baffle 2 is 600mm, baffle 2 is divided into left basin I room 5 and the II rooms of basin 3 on right side with the basin inner space, the drain pipe 1 of drainer is received in I room 5 of basin, this drain pipe lower extreme mouth of pipe 6 is 200mm apart from the bottom of the basin, outer drain pipe 4 is being connected to II rooms of basin 3 bottoms. The chamber I5 of the water tank is filled with condensed water to seal the lower end pipe orifice 6 of the drain pipe, so that coal gas cannot overflow from the drain pipe 1, and excessive condensed water turns over the partition plate 2 and is discharged from the outer drain pipe 4 to a sewer pipeline.
