Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

A device for collecting and discharging outward-escaping hot gas at a sintering furnace mouth comprises a conical cover 1 which is fixedly arranged right above the sintering furnace mouth and is provided with an opening at the lower end face, a steam pipe 2 communicated with the upper end of the conical cover 1, and a condensation pipe 3 communicated with the steam pipe 2, wherein the diameter of the lower part of the conical cover 1 is larger than that of the upper part, the steam pipe 2 is vertically arranged, and an included angle alpha is formed between the condensation pipe 3 and the horizontal line and is = 10-30 degrees. And the upper end of the condensation pipe 3 is sealed and the lower end is opened.

The lower part of the inner edge of the conical cover 1 is fixedly provided with an annular water storage tank 4. One side of the conical cover 1 is provided with a first drain valve 5, and the first drain valve 5 is communicated with the annular water storage tank 4. An upward exhaust fan 7 is fixedly arranged in the conical cover 1. The lower part of the conical cover 1 is fixedly provided with a temperature sensor 6. The condensation pipe 3 is a plate-shaped hollow structure. A water storage tank 8 with an opening at the upper end surface is fixedly arranged below the lower end of the condensation pipe 3, and a second drain valve 9 communicated with the water storage tank 8 is arranged at one side of the water storage tank 8.

The conical cover 1 is in a flared shape with a small diameter at the upper end and a large diameter at the lower end, and when steam escapes, the steam drifts upwards and is collected and absorbed by the conical cover 1. The steam pipe 2 is vertically arranged, so that the steam can rapidly drift upwards, and the resistance of the steam is reduced. Condenser pipe 3 is the aluminum alloy material, can have quick radiating effect, after steam gets into condenser pipe 3, scatter fast in condenser pipe 3, thereby the condensation becomes the water globule at the upper end inner wall condensation of condenser pipe 3, because there is contained angle alpha between condenser pipe 3 and the water flat line, consequently the water globule receives the component along the gravity of condenser pipe 3 distribution direction, thereby the inclined plane lapse of the upper end inner wall along condenser pipe 3, final water globule assembles into rivers and flows out from the lower extreme opening part of condenser pipe 3, gas after the condensation also discharges in the atmosphere from the lower extreme opening part of condenser pipe 3.

The annular water storage tank 4 is welded at the inner lower edge of the conical cover 1, one surface of the annular water storage tank 4 facing the upper end of the conical cover 1 is opened, when steam rises into the conical cover 1, because the steam and the inner wall of the conical cover 1 have temperature difference, a small amount of water drops can be formed on the inner wall of the conical cover 1, the water drops flow downwards to the annular water storage tank 4, and the water drops are prevented from dripping from the lower edge of the conical cover 1.

First drain valve 5 plays the effect of the water of storing in the discharge annular aqua storage tank 4, because the condensate water yield of annular aqua storage tank 4 is less, before not installing first drain valve 5, also can oneself evaporate through long-time drying, but after installing first drain valve 5, avoided the comdenstion water to gather in annular aqua storage tank 4, and then avoided magazines such as dust that the aquatic erodeed to pile up in annular aqua storage tank 4.

Exhaust fan 7 upwards bleeds, and steam rises to the cone cover 1 in the back, can further accelerate the flow velocity of steam through exhaust fan 7 to it is clear up to be faster to collect the steam.

The temperature sensor 6 is electrically connected with the exhaust fan 7, and when the steam rises, the temperature sensor 6 detects the temperature change at the lower part of the conical cover 1, so that the exhaust fan 7 is started, and the corresponding speed of the exhaust fan 7 is accelerated.

Condenser pipe 3 is the broadplate structure, and the middle part of broadplate is equipped with the cavity, has increased the area of contact of condenser pipe 3 with steam, has increased the condensation area of steam promptly for the condensation rate of steam.

The up end opening of storage water tank 8, and be located the condenser pipe 3 lower extreme under, after steam condenses into the drop of water in condenser pipe 3, water flows out from the lower extreme opening part of condenser pipe 3, and then in flowing into storage water tank 8, opens second drain valve 9 to can discharge water from storage water tank 8 in, collect the comdenstion water through storage water tank 8, can collect the comdenstion water and concentrate and carry out sewage treatment, reduced the emission of aquatic harmful substance.

The included angle alpha represents the gradient of the condensing pipe 3, and the excessively large gradient of the condensing pipe 3 easily causes short steam condensing time and further causes incomplete steam condensation; the slope undersize of condenser pipe 3 easily leads to the speed that flows downwards behind the steam condensation to the drop of water to be slower, and then easily leads to the comdenstion water to drip the lower extreme inner wall of condenser pipe 3 down to make the drop of water that is higher than steam pipe 2 position flow backward steam pipe 2. The included angle alpha is 10-30 degrees, which not only ensures that the steam is condensed more thoroughly, but also ensures that water drops only slide on the inner wall of the upper end of the condensing tube 3.

When the device is used, a furnace mouth of the sintering furnace is opened, a large amount of steam escapes from the furnace mouth and rises, and the temperature sensor 6 detects the temperature change of the lower part of the conical cover 1, so that the exhaust fan 7 is started, and the corresponding speed of the exhaust fan 7 is accelerated. In the conical cover 1 was collected to steam, flow upwards fast under the effect of air discharge fan 7, thereby flow in condenser pipe 3 through steam pipe 2, after steam got into condenser pipe 3, scatter fast in condenser pipe 3, thereby become the globule at the upper end inner wall condensation of condenser pipe 3, because there is contained angle alpha between condenser pipe 3 and the water flat line, consequently, the globule receives the component of the gravity along condenser pipe 3 distribution direction, thereby slide downwards along the inclined plane of the upper end inner wall of condenser pipe 3, finally the globule assembles into rivers and flows out from the lower extreme opening part of condenser pipe 3, gas after the condensation also discharges in the atmosphere from the lower extreme opening part of condenser pipe 3. The water flowing out from the opening at the lower end of the condensation pipe 3 is collected in the water storage tank 8, the second drain valve 9 is opened, so that the water can be discharged from the water storage tank 8, condensed water is collected through the water storage tank 8, the condensed water can be collected and concentrated for sewage treatment, and the discharge of harmful substances in water is reduced.

The utility model can rapidly collect steam escaping from the furnace mouth of the sintering furnace, rapidly reduce the temperature of the furnace mouth, avoid the workers from being scalded by the steam, and eliminate the security threat to the workers; and the utility model discloses can clear up the steam of fire door fast, avoid steam to the interference of staff's sight to guarantee sintered flux production process flow's normal operating, improved the efficiency of sintered flux production.
