Abstract
The invention provides a silver and copper molten pool smelting furnace with an adjustable outlet smoke flow velocity device. A furnace body of the silver and copper molten pool smelting furnace is divided into a converting region and a settling region through a partition wall, smoke gas outlets of the converting region and the settling region are respectively provided with pressure arch water jackets, and the adjustable outlet smoke flow velocity device is characterized in that the lower parts of the pressure arch water jackets are parallelly connected with adjusting water jackets, and water inlets and water outlets of the adjusting water jackets are arranged at the outer part of the furnace body. The lower parts of the pressure arch water jackets are parallelly connected with the adjusting water jackets, and the goal of controlling the flow velocity of smoke gas at the smoke outlet part to be constant is reached through adjusting the area at the smoke gas outlet part. When the flow velocity of smoke gas at the smoke outlet part is controlled to be 9m/s, the hearth pressure is micro-positive pressure (0 to 30Pa), at the pressure, the pulverized coal combustion is full, the combustion heat utilization rate is high, and meanwhile, the environment pollution is greatly reduced.
Description
Technical field
The present invention relates to silver copper bath smelting furnace, particularly a kind of silver copper bath smelting furnace with outlet flue gas flow rate tunable arrangement.
Background technology
Baiyin Nonferrous Metal Group Co., Ltd. copper industry company (former silver company smeltery is hereinafter to be referred as copper industry company) is the main project that national Firist Five-Year Plan is built.Nineteen sixty goes into operation, and original design is reverberatory smelting technology, produces 3.21 ten thousand tons of cathode coppers per year.Adopted domestic unique " Baiyin copper smelting process " melting technology to replace the reverberatory smelting technology that falls behind in 1980, after having realized oxygen-enriched air smelting, can reach and produce 80000 tons of cathode copper throughput per year with China's independent intellectual property right.This technology though carry out some technological transformations, owing to receiving many-sided reasons such as history, system and business economic benefit, fails on technical equipment, to carry out transformation comprehensive, system through the practice production of two more than ten years.System device is aging serious, and each item energy unit consumption all is higher than level of the same trade, production process " three wastes " discharging severe overweight, and problem of environmental pollution is outstanding.Particularly should work as by the special-purpose silver copper bath smelting furnace of " Baiyin copper smelting process " melting technology
When strengthening the treatment capacity in domestic ore deposit, change greatly owing to go into stove material composition, output is also by 50,000 tons/year to 150,000 tons/year adjustable scale, so that the exhaust gas volumn of silver copper bath smelting furnace blowing district and settling region is at 32000Nm
3/ h to 45000Nm
3Interior on a large scale variation the between the/h, and make the flue gas flow rate of said blowing district and settling region exhanst gas outlet extremely wayward, cause the low or surrounding environment severe contamination of heat utilization efficiency of pulverized coal friring.For this reason, adopt the whole way of raising or force down the exhanst gas outlet water jacket to solve this problem, will be undertaken by manual work fully but construct, difficulty is very big and effect is general.
Summary of the invention
The present invention provides a kind of silver copper bath smelting furnace with outlet flue gas flow rate tunable arrangement; It is constant that the flue gas flow rate of silver copper bath smelting furnace blowing district and settling region exhanst gas outlet is remained, and the heat utilization efficiency of solution pulverized coal friring is low or the problem of surrounding environment severe contamination.
For this reason; Adopt following technical scheme: a kind of improved silver copper bath smelting furnace with outlet flue gas flow rate tunable arrangement; The body of heater of this silver copper bath smelting furnace is divided into blowing district and settling region through partition wall; The smoke outlet of this blowing district and settling region is provided with presses the arch water jacket, and described outlet flue gas flow rate tunable arrangement is: below said pressure arch water jacket and connect the adjusting water jacket, the entery and delivery port of this adjusting water jacket is arranged on the body of heater outside.
The present invention is below pressure arch water jacket and connect the adjusting water jacket, is the area through the adjusting smoke outlet, and reaching control smoke outlet flue gas flow rate is the constant purpose.When the smoke outlet flue gas flow rate was controlled at 9m/s, furnace pressure was that (0～30Pa), under this pressure, pulverized coal friring is abundant, and the incendiary heat utilization efficiency is high, has alleviated environmental pollution simultaneously greatly for pressure-fired.
The present invention simultaneously also has following advantage:
1. effectively capture the flue dust in the stove, improve the direct yield of copper;
2. heat passage between enhancing high temperature flame and the melt strengthened heat exchange, improves heat utilization efficiency.
3. after pressing the height control of arch, effectively solve the adhesion problem that symmetrical full reclining formula copper bath smelting furnace waste heat boiler exists.
Description of drawings
Fig. 1 is the structural representation of invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
With reference to figure 1; A kind of improved silver copper bath smelting furnace with outlet flue gas flow rate tunable arrangement; The body of heater of this silver copper bath smelting furnace is divided into blowing district 2 and settling region 5 through partition wall 3; The smoke outlet of this blowing district 2 and settling region 5 is provided with presses arch water jacket 1, and described outlet flue gas flow rate tunable arrangement is: below said pressure arch water jacket 1 and connect and regulate water jacket 4, the entery and delivery port of this adjusting water jacket 4 is arranged on the body of heater outside.
Said adjusting water jacket 4 is molten copper water cast that set inside has copper pipe, and the quantity of this copper pipe is more than at least two.
The adjustment that the height dimension of said adjusting water jacket 4 can adapt according to the size work of control flue gas flow rate.
Claims (2)
1. one kind has the improved silver copper bath smelting furnace that exports the flue gas flow rate tunable arrangement; The body of heater of this silver copper bath smelting furnace is divided into blowing district and settling region through partition wall; The smoke outlet of this blowing district and settling region is provided with presses the arch water jacket; It is characterized in that: described outlet flue gas flow rate tunable arrangement is: encircle the below of water jacket (4) and connect in said pressure and regulate water jacket (1), the entery and delivery port of this adjusting water jacket is arranged on the body of heater outside.
2. a kind of improved silver copper bath smelting furnace with outlet flue gas flow rate tunable arrangement according to claim 1, it is characterized in that: described adjusting water jacket (1) is the molten copper water cast that set inside has copper pipe.
