The distribution device adopts the circular distribution box to improve the distribution box in the past, realizes the equidistant distribution of aluminum oxide in the distribution box, effectively increases the distribution precision and the distribution quantity, reduces the occupied space for distribution and is favorable for purifying the configuration in the system and improving the purification efficiency.
Description
Technical field
The utility model relates to a kind of sub-material equipment, particularly relate to a kind of in the electrolytic aluminium factory flue gas purification system round alumina multiple spot sub-material equipment.
Background technology
In existing electrolytic aluminium factory flue gas purification system, need adsorb hydrogen fluoride in the flue gas with aluminum oxide, discharge after making flue gas reach state specified standards.In this process, fresh aluminum oxide need be assigned in the flue before every fly-ash separator.Past, the general method that adopts chute to decide the hole was directly distributed, and perhaps distributed through the form of distribution box.For the less purification system that is not more than 10 fly-ash separators, fresh aluminum oxide can adopt chute to carry out more rough distribution; And for the bigger system of 24～32 fly-ash separators, it is just infeasible to adopt chute to carry out sub-material, and oversize because of pipeline, the blanking amount of every section chute can not accurately be controlled, and usually causes terminal several fly-ash separators to lack the situation of material.
And general distribution box mostly is the rectangle distribution box, and its sub-material point is subjected to the restriction of shape, is difficult to realize when the more a plurality of sub-material point of needs, as greater than 10, can only increase the number of distribution box like this, and improve the chute drop, carry out stage trapping to increase sub-material progression.Will increase the absolute altitude of aluminum oxide storage bunker feed opening by the form that increases sub-material progression, reduce the utilization ratio of bunker, increase construction cost.The aluminum oxide of boiling state can flow out from the less pipeline of resistance just as mobile water in addition.The different discharge ports of rectangle distribution box are different apart from the blanking point distance, can cause certain sub-material error.
The utility model content
The utility model is a kind of circular multipoint distribution box that provides for solving the problems of the technologies described above, and its objective is in order to realize the even sub-material of aluminum oxide in the purification system, reduces the floor space of distribution box, increases sub-material quantity, reduces system's drop.
For reaching above-mentioned purpose, the utility model is to realize like this:
A kind of circular multiple spot sub-material, it comprises air chamber, material chamber, be installed in opening for feed and exhaust outlet, the air chamber lower end of material on the chamber is provided with discharge port and inlet pipe, expect that wherein chamber cross-section is circular, it is circular air chamber that the lower end of material chamber connects cross section, be connected by air permeable plate between material chamber and the air chamber, expect the indoor division board that is provided with, division board is installed on the air permeable plate, division board is arranged on the position between opening for feed and the discharge port, and division board is provided with material feeding hole.
Upper end, described material chamber is equipped with slag-drip opening and porthole.
Described division board is an annular.
The quantity that is provided with of discharge port is 3-15 when material chamber diameter is 1 meter.
Described discharge port is circumferentially uniform along the material chamber.
Wear-resistant ceramic is set or is coated with the wear-resistant paint layer around the described material feeding hole.
Advantage of the present utility model and effect are as follows:
The utility model adopts the form of circular distribution box, the distribution box form in past is improved, realized aluminum oxide equidistant sub-material in distribution box, the precision of sub-material and the quantity of sub-material have effectively been increased, reduced taking up room of sub-material, helped the configuration of purification system inside and improve purification efficiency.
