Abstract
An antimony white furnace with a reverberatory furnace structure belongs to nonferrous metallurgy furnace equipment. Two circular reaction chambers are hung in the antimony white furnace, the upper outlets of the reaction chambers are communicated with an air cooling flue, and the lower outlets of the reaction chambers face to a high-temperature antimony melt; the bottom surface of the furnace at the lower part of each reaction chamber is inserted with a refractory mortar air supply pipe for blowing air in the melt. The furnace oxidizes the metal antimony into antimony trioxide steam in a reaction chamber under the self-heating condition, and then the antimony trioxide steam is violently cooled into spherical antimony trioxide powder in an air cooling flue.
Description
The invention belongs to the nonferrous metallurgical equipment for preparing antimonous oxide with the oxidation of metallic antimony pyrogenic process, it is to adopt horizontal reverberatory furnace that general pyrogenic process prepares antimonous oxide, metallic antimony melts at the stove internal heating, under 800 ℃ temperature, in melt, blast air, antimony is oxidized, and the antimonous oxide steam of generation is extracted out outside the stove, becomes the antimonous oxide pressed powder with air cooling.There is following problem in the antimonous oxide of this reverberatory furnace output: the influence factor of (1) wayward whiteness, and antimonous oxide containing metal antimony height, color is bad, the leukorrhea grey; (2) can not control the generation of weisspiessglanz at high price, antimonous oxide content is on the low side; (3) in the whole volatilization process of antimonous oxide, keep processing temperature with oil or electrically heated, energy consumption is big.
The purpose of this invention is to provide and a kind ofly prepare the stibium trioxide stove of antimonous oxide with pyrogenic process oxidized metal antimony, this stibium trioxide stove carries out voloxidation under field conditions (factors), product trioxygen-containingization two antimony composition height, and color is pure white, and energy consumption is low.
The present invention is a kind of stibium trioxide stove with reverberatory furnace structure, this stibium trioxide stove is laterally to be hung with two refractory mortar rounding cylindricality reaction chambers by the reverberatory furnace furnace roof in stove, the top outlet of reaction chamber is by adapting pipe and air cooling flue UNICOM, lower part outlet is facing to the antimony bath surface, be inserted with fire-resistant clay air feed pipe in the antimony melt at the bottom of the reaction chamber lower furnace, in order to drum pressurized air (being primary air) in the antimony melt.Along central axis a downward air feed pipe of outlet is installed on reaction chamber top, in order to following antimony bath surface blowing compressed air (being secondary air).Antimony added in the stove melt, under 900～1000 ℃ temperature, blast first and second air, remove the heating thermal source, under the exothermic oxidation reaction condition, antimony is oxidized to antimonous oxide, and rising from reaction chamber enters cooling stack, in cooling stack, with the glomerate antimonous oxide powder of a large amount of air quick cooling.In oxidising process, can add metallic antimony indirectly at the service gate of furnace side, in stove, melt, constitute continuous oxidation operation.
The present invention prepares the stibium trioxide stove of antimonous oxide, has the following advantages: (1) can adjust first and second air capacity, makes oxidizing reaction complete, and the ANTIMONY TRIOXIDE SB 203 99.8 PCT whiteness of output is good; (2) react room temp greater than 900 ℃, and stable, the high price weisspiessglanz virtually completely decomposes, and product trioxygen-containingization two antimony can reach more than 99.6%; (3) except that blow-on deposite metal antimony need heat, in whole antimony voloxidation process, utilize the oxidation liberated heat fully, the maintenance process processing temperature, product energy consumption is very low.
The present invention has been used for industrial production, when taking following best-of-breed technology condition: 950～1000 ℃ of furnace temperature, primary air amount 9m
3/ h, secondary air amount 100m
3/ h; Cooling air 14000m
3About/h.Operation under self-heat condition obtains qualified antimonous oxide.
Claims (2)
1, a kind of stibium trioxide stove of reverberatory furnace structure, in order to be under the self-heat condition at whole weisspiessglanz volatilization process, carry out the antimony metal oxidation and prepare antimonous oxide, it is characterized in that laterally in stove, hanging two cylindrical reaction chamber along furnace roof, the outlet of reaction chamber top is the air cooling flue UNICOM of spherical powder with cooling antimonous oxide steam, and lower part outlet is 900～1000 ℃ the interior antimony bath surface of stove facing to furnace temperature; In the antimony melt at the bottom of each reaction chamber lower furnace, be inserted with an air feed pipe; A secondary air feed pipe that outlet is downward is housed on each reaction chamber top.
2, by the described stibium trioxide stove of claim 1, it is characterized in that inserting a molten intravital air feed pipe is the refractory mortar tubulation.
