Description
Technical field
The utility model belongs to cement clinker production line auxiliary facility, refers to the clearing device of the preheater obstruction of cement clinker production line especially.
Background technology
At present, the novel concrete clinker production line all adopts the suspension preheating technology, and its item key equipment is a preheater.In the production, material reduces effective barrel dliameter, even stops up fully because complicated physicochemical change very easily articulates accumulation on preheater inner barrel, greatly influences the continous-stable operation of production line, reduces the yield and quality of grog.Preheater is stopped up, and normally used method for cleaning has following several: 1, manually disclose stifled, exactly with instruments such as high pressure gas, drill rods directly with skinning or stop up material and clean out, time-consuming, the effort of this method operates being absolutely unsafe again; 2, use the water blast gun block clearing, this method only is applicable to stops clearing up skinning during the kiln, and the equipment manufacturing cost costliness, and failure rate is also high; 3, air cannon block-removing, this method fast and safely, but that equipment is installed is more, and bad to serious obstruction and skinning block clearing effect.
Summary of the invention
For the accumulation hidden danger of in time removing on the preheater inner barrel that articulates is carried out pre-treatment and is removed obstruction fully, make effective barrel dliameter works better, to adapt to of an urgent demand of modern cement producing line to the lasting running of continuous high-efficient, while is simple to operate again, installation is easy to make, to improve the validity of this system, also to take into account cheaply, reduce cost of investment.
The cement preheater is disclosed stifled system fast, at least feed a water inlet pipe in preheater tube cone and straight-tube portion, at preheater tube outer setting water cannon, water cannon is a cavity, water inlet pipe, high-pressure pipe and vapor pipe by valve control are set on the cavity, the cavity bottom sets out water pipe, sets gradually valve and check valve on the rising pipe, and the water inlet pipe that feeds preheater is connected in the check valve outlet.
Feed preheater tube cone or/and straight-tube portion can be a plurality of water inlet pipes, a plurality of water inlet pipes preferably are provided with ringwise, and preheater tube cone is or/and the water inlet of straight-tube portion is concentrated like this, and expanded by heating effect maximum can reach the best and disclose stifled effect.
In order to realize automatic control, the valve of control water inlet pipe, high-pressure pipe and vapor pipe is an electric control valve, these three electric control valves are connected with the DCS controller respectively, the valve that is provided with on the outlet conduit also is an electric control valve, this electric control valve is connected with the DCS controller, on outlet conduit, water monitor is set, this water monitor is connected with the DCS controller.
The principle of work of native system is: utilize water expand rapidly 1000 times the phenomenon of back of vaporizing in high-temperature material, water is passed through a water filling device, directly squeeze into water in the high-temperature material fast by high-pressure air, make it expand blast, it is broken to utilize explosion energy will stop up that material washes away, skinning shakes, and realizes the block clearing purpose, when expanding blast, closed check valve prevents the airflow influence water cannon.Control section is, utilize pressure transmitter, monitor the preheater internal pressure in real time and change, grasp the materials inside flow state, by articulating accumulation and stopping state in the DCS data processing judgement passage, carry out real-time block clearing according to setup parameter control water cannon system then.But this system not only can control but also manual operation automatically.
This system is applicable to all cement production enterprises and is similar to the suspended preheater system that cement clinker is produced.With respect to conventional block clearing method, native system has tangible advantage: safety, and efficient, economy, reliable, construction is simple, and the operative technique difficulty is little.Through the use of enterprise's several years, prove that it can effectively reduce preheater obstruction number of times and shortening is disclosed the stifled time more than 2/3, be a kind of utility model invention that metallurgical building material industry is promoted that is highly suitable for.Safety, it is splendid to disclose stifled effect, and can effectively reduce and stop up number of times what result in blockage, can create considerable economic for enterprise.
