The device playing a key role in the process layout of multi-point coal feeding is a coal distributor, a plurality of three-way coal distributors are mostly used in the market at present, one is divided into two and then two is divided into four, the arrangement of the plurality of coal distributors increases the total installation height of the whole equipment, meanwhile, the resistance of the whole pulverized coal conveying system is too large due to too many elbows, the coal distribution effect is very unsatisfactory, and a series of problems such as unstable coal pressure, temperature fluctuation of a decomposing furnace, skinning caused by local high temperature, standard exceeding of environmental protection data and the like easily occur in the firing process.
Disclosure of Invention
The utility model aims to solve the technical problem that just not enough to above-mentioned prior art provides a multiple spot branch coal device that can steady voltage carry, and its simple structure, reasonable in design have simplified the pipeline arrangement that the buggy was carried greatly, have reduced system resistance simultaneously, can carry out the steady voltage to the buggy and carry.
The utility model adopts the technical proposal that: the utility model provides a multiple spot coal device that divides that can steady voltage carry, includes that the steady voltage carries the storehouse, the steady voltage is carried the storehouse and is cylindric for inside hollow, steady voltage is carried the storehouse top and is equipped with a plurality of coal outlets, and a plurality of coal outlets evenly set up around steady voltage transport storehouse top center, steady voltage is carried storehouse bottom center and is equipped with into the coal mouth, the pipe connection ware is installed respectively to coal outlet and the free end that advances the coal mouth, steady voltage is carried the storehouse, is advanced the inner wall of coal mouth and coal outlet and all has the wear-resisting coating of one deck.
Preferably, the lower part of the pressure stabilizing conveying bin is conical, the taper of the lower part of the pressure stabilizing conveying bin is 55-70 degrees, and the conical part of the bottom of the pressure stabilizing conveying bin is connected with the coal inlet.
Preferably, the number of the coal outlets is 2-6.
Preferably, the pipeline connector is a pipeline connecting flange or a pipeline quick-release joint.
The beneficial effects of the utility model reside in that:
(1) the coal outlets are uniformly distributed on the pressure stabilizing conveying bin, so that the pulverized coal is conveyed uniformly;
(2) the coal pipe can be quickly connected with the pipeline connector, so that the pulverized coal is uniformly conveyed;
(3) the wear-resistant coating is arranged, so that the wear resistance in the coal inlet, the coal outlet and the pressure-stabilizing conveying bin can be effectively improved, and the service life of equipment is prolonged;
(4) the pressure stabilizing conveying bin is cylindrical, and the Roots blower is used for feeding coal powder through the coal inlet, so that the mixing degree of coal gas can be increased by utilizing the spouting effect and the top hitting back mixing effect of air flow, and the effect of stabilizing the flow is achieved;
(5) the steady voltage is carried the storehouse lower part and is the coniform, and the buggy gets into the back from the coal feed mouth of pyramis, and the sectional area in the steady voltage is carried the storehouse increases for the velocity of flow in the steady voltage is carried the storehouse and is reduced, thereby reduces the frictional resistance loss, is favorable to the buggy evenly to get into in every coal outlet, thereby spouts into the decomposing furnace through the coal pipe that a plurality of coal outlets are connected under wind-force and carries out the multiple spot dispersed combustion, has improved the burn-off rate of burning.
The utility model discloses compare in traditional coal distributor, can effectively reduce coal distributor use quantity, simplify the pipeline arrangement that the buggy was carried by a wide margin, and divide the coal even, prevent stifled wear-resisting, still solved the coal simultaneously and pressed the fluctuation problem, improved buggy utilization efficiency.
