The cyclone filter comprises a water feeding pipe, a barrel body, a sewage discharging pipe, a sewage discharging valve, a sewage depositing hopper, a water discharging pipe, a filtering net and an exhausting pipe, wherein the water feeding pipe is arranged on the side wall of the barrel body and is communicated with the inner part of the barrel body; the sewage discharging pipe is arranged at the bottom part of the barrel body and is communicated with the inner part of the barrel body; the sewage discharging pipe is provided with the sewage discharging valve; the sewage depositing hopper is arranged in the barrel body above the sewage discharging pipe; the water discharging pipe is arranged at the top part of the barrel body, is communicated with the inner part of the barrel body and is internally provided with a filtering net; and the exhausting pipe is arranged at the top part of the barrel body. The cyclone filter disclosed by the utility model has the advantages that the purpose of removing the impurities of the slag-flushing water in the blast furnace can be achieved in the barrel body of the cyclone filter by a matching mode of cyclone and settlement, the slag-flushing water is settled and discharged from the bottom part, and cleaner water is discharged from the water discharging pipe at the upper part, so that the possibility of blocking the heat exchanger in the system can be effectively reduced.
Description
Technical field
The utility model relates to the filter that heating system is used, and particularly relates to a kind of cyclone filter that can recycle the system that blast furnace slag quenching water heat heats.
Background technology
Current domestic each Iron Works slag is processed representational technique and can be divided into Lhasa (RASA) method, end filter (OCP) method, Yin Ba (INBA) method, Tula (TYNA) method, good permanent method and Ming Teke (MTC) method.In utilizing flushing cinder hydro-thermal amount process, because flushing cinder water water quality is different, run into difficulty in various degree.Flushing cinder water under most residues processing techniques can be to producing wearing and tearing and stopping up with hot equipment; Comparatively speaking, the flushing cinder water dregginess under end filtering technology is few, and abrasion condition is lighter, but in use also can produce obstruction because of constantly separating out slag wool in pulp water.In order to reach safety and stability, utilize the object of flushing cinder hydro-thermal amount, must solve the wearing and tearing that produce in process for flushing cinder water conservancy, Corrosion blockage problem.
Recent year utilizes the technique of blast furnace slag quenching water heat can roughly be divided into direct utilization and heat exchange utilizes two kinds, wherein, without filtering directly to utilize, does not solve pulp water wearing and tearing, Corrosion blockage problem completely, and system is very easily stopped up, can not stable operation; And utilize after filtering, solved pulp water wear problem and a part of suspension blockage problem, but the slag wool of separating out in pulp water can cause system jams, and filtering technique is invested and maintenance cost is high.Without filtering direct heat transfer, often adopt wide runner heat exchanger, have wearing and tearing and the low problem of heat exchange efficiency, can not solve blockage problem completely; After filtering there is filtering technique investment and the high problem of maintenance cost in heat exchange, also has heat exchanger blockage problem simultaneously.Therefore, how blast furnace slag quenching water being carried out effectively filtering effectively to remove foreign material, avoid heating system to stop up, need not often safeguard to this filter again (as renew cartridge more), is to need the problem that solves thereby reduce costs.
Utility model content
The technical problems to be solved in the utility model is to provide the cyclone filter that a kind of blast furnace slag quenching water low temperature exhaust heat heating system is used, can effectively filter the foreign material in blast furnace slag quenching water, avoid stopping up heat exchanger, and maintenance cost is low, thereby solve the existing heat-exchange system of blast furnace slag quenching water waste heat that utilizes, easily stop up the high problem of maintenance cost in use.
For solving the problems of the technologies described above, the cyclone filter that the utility model provides a kind of blast furnace slag quenching water low temperature exhaust heat heating system to use, comprising:
Water inlet pipe, cylindrical shell, blow-off pipe, blowoff valve, dirt collecting bucket, outlet pipe, screen pack and blast pipe; Wherein,
Described water inlet pipe is arranged on described cylinder lateral wall, and is communicated with in described cylindrical shell;
Described blow-off pipe is arranged on the bottom of described cylindrical shell, and is communicated with in described cylindrical shell;
Described blowoff valve is set on described blow-off pipe;
In the described cylindrical shell of described blow-off pipe top, described dirt collecting bucket is set;
Described outlet pipe is arranged on the top of described cylindrical shell, and is communicated with in described cylindrical shell, and described screen pack is set in described outlet pipe;
Described blast pipe is arranged on the top of described cylindrical shell.
The utility model beneficial effect is: the mode that this cyclone filter can make blast furnace slag quenching water coordinate with eddy flow and sedimentation in this cyclone filter cylindrical shell reaches the object of removing impurity in it, and discharge from bottom sedimentation, cleaner water outlet is discharged from top outlet pipe.Thereby in effectively reduction system, stop up the possibility of heat exchanger.
