Abstract
The utility model discloses a high-temperature particle separator for an RH (relative humidity) dry-type vacuum-pumping system. The high-temperature particle separator comprises a cavity I and a cavity II, wherein the cavity I and the cavity II are enclosed by a shell body and a separation plate and are communicated with each other; the shell bodies of the cavity I and the cavity II are respectively provided with an air inlet and an air outlet; an aggregate bin is respectively arranged at the bottom of the cavity I and the cavity II; and a discharging valve is arranged at the bottom of the aggregate bin. As the high-temperature particle separator is adopted to separate the addition material particles like Al, C and the like mixed in the high-temperature gas before the high-temperature gas enters into a dry-type vacuum pump set, the particles are prevented form entering into the vacuum pump set along with the airflow, and the damage to the vacuum pump set can be avoided.
Description
Technical field
The utility model relates to a kind of steelmaking equipment, particularly a kind of high-temperature particle separator that is used for RH dry type pumped vacuum systems.
Background technology
The RH vacuum processing technique is a kind of steel secondary refining technology that is used for production high-quality steel.In the whole technology, the molten steel metallurgical reaction is to carry out in block has the vacuum tank of refractory lining, the bottom of vacuum tank is the dip pipe of two band refractory linings, the hot bending pipe is equipped with on top, pumped gas is extracted out by vacuum extractor and is discharged through the hot bending pipe, thus the RH vacuum processing technique because adopt molten steel the technology of vacuum tank circulation reach the processing time short, efficient is high, can be adopted in a large number by the converter operation with the advantage of revolving furnace continuous casting coupling.
The RH dry type pumped vacuum systems that adopts mainly comprises vacuum tank and vacuum extractor at present, wherein vacuum extractor adopts the dry vacuum pump group, because of adding additives such as metal A l, a C material in the cyclic process of vacuum tank molten steel, this additive can be taken out of by air-flow in vacuum, it vacuumizes the particle temperature of taking out of and reaches as high as 1300 ℃, therefore must take suitable mode to prevent that high-temperature particle from entering in the pump housing of dry vacuum pump group, avoid the vavuum pump group is caused damage.
At above-mentioned deficiency, a kind of high-temperature particle separator of the RH of being used for dry type pumped vacuum systems need be provided, it can be separated high temperature additive particle, prevent that it from entering dry type vacuum pumping pump group and causing damage to equipment such as vavuum pump groups.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of high-temperature particle separator of the RH of being used for dry type pumped vacuum systems, it can be isolated the high temperature additive particle that is mingled with in the air flue, prevent from that high temperature additive particle from entering it to be caused damage in the vacuum pumping pump group.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-temperature particle separator that is used for RH dry type pumped vacuum systems, comprise by housing and separating plate and surround die cavity I and the die cavity II that is interconnected jointly, be respectively arranged with air inlet and gas outlet on the housing of die cavity I and die cavity II, the bottom of die cavity I and die cavity II is provided with aggregate bin, and the aggregate bin bottom is provided with discharge valve.
Further, in described die cavity I and the die cavity II cooling coil is set respectively;
Further, also be provided with explosion proof door on the housing;
Further, described aggregate bin is an inversed taper platform shape.
The beneficial effects of the utility model: because before high-temperature gas enters the dry vacuum pump group, adopt high-temperature particle separator of the present utility model that the additive particles such as Al, C that are mixed in the high-temperature gas are separated, prevent that it from entering the vavuum pump group with air-flow, causes damage to the vavuum pump group.Simultaneously, built-in cooling coil can also cool off high-temperature gas, further equipment such as vavuum pump group is played a protective role.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: a kind of high-temperature particle separator that is used for RH dry type pumped vacuum systems, comprise by housing 1 and separating plate 2 and surround die cavity I 3 and the die cavity II 4 that is interconnected jointly, be respectively arranged with air inlet 5 and gas outlet 6 on the housing of die cavity I and die cavity II, the bottom of die cavity I and die cavity II is provided with aggregate bin 7, and the aggregate bin bottom is provided with discharge valve 8.In the RH dry type pumped vacuum systems, adopt high-temperature particle cooling separator of the present utility model that the high temperature additive particle that is mingled with in the air flue is isolated, prevent from that high temperature additive particle from entering it to be caused damage in the vacuum pumping pump group.Concrete operation principle is: high-temperature gas enters the die cavity I by air inlet 5, separating plate 2 has changed the flow direction of air-flow, make the gas die cavity II of flowing through, 6 outflows from the gas outlet at last, be mixed in and under the effect of gravity, drop in the aggregate bin 7 of bottom after additive material such as Al, C in the high-temperature gas strike separating plate, by discharge valve 8 it is drawn off separation at last, prevent that it from entering the dry vacuum pump group it is caused damage.
In the present embodiment, in die cavity I and the die cavity II cooling coil 9 is set respectively.Feed cooling water in the cooling coil, high-temperature gas is played cooling effect, thereafter equipment such as vavuum pump group are played further protective effect.
In the present embodiment, also be provided with explosion proof door 10 on the housing 1.Explosion proof door 10 is set prevents the too high security incidents such as blast that cause of die cavity internal gas pressure, strengthened security.
In the present embodiment, described aggregate bin 7 is an inversed taper platform shape.Inversed taper platform shape structure can be collected aggregate particle aggregate bin bottom, easy-unloading automatically.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
