Description
Technical field
The present invention relates to precious metal smelting tail gas clean-up and process, be specifically related to a kind of rotary furnace smoke eliminator.
Background technology
At present, rotary furnace smelting exhaust sulfur dioxide and the arsenic content of the electrolytic lead earth of positive pole are high, also contain the granule dust of a large amount of utilities, unprocessed direct discharge, and both contaminated environment, the utility in tail gas also can not get reclaiming, and causes the wasting of resources.
Prior art has on December 19th, 1977, by the Japanese Patent Room clear 52-148482A of JP, a kind of liquid washing type deodour method is disclosed, and specifically disclose a kind of equipment, wherein it has the washing column of the suitable desulfurizing tower of two-stage, two washing column structures are identical, the outer a set of identical water spray circulation system of separate connection of tower, exhanst gas outlet connects the first washing column by gas tank, outlet connects the second washing column, spray system is stayed groove by the water or the liquid storage that are equivalent to precipitate and separate pond, water circulating pump, sprinkling equipment forms, the bottom of two-stage washing column stays groove to be connected by being equivalent to the pipeline of blowdown ditch with storage, water circulating pump stays water or liquid medicine in groove by pipeline, to introduce the spray head of the middle and upper part of washing column storage, storage stays groove by water inlet and delivery port, and the outlet of one-level is connected with the entrance of another grade.This structure is due to flue gas will flow through two-stage washing column and sprinkling equipment, and gas circuit is not smooth; Certainly will increase the latus rectum of connecting line, equipment installation volume is large; In groove is stayed in the storage of water or liquid, water inlet is to delivery port, and only a pond isolates, and current partial short circuit is unfavorable for the precipitation of sulphur compound.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rotary furnace smoke eliminator.This appliance arrangement installation volume is little, and the flue gas after this device is processed can directly discharge, and free from environmental pollution, the utility efficiency simultaneously reclaiming in tail gas is high.
Technical scheme of the present invention is: a kind of rotary furnace smoke eliminator, is comprised of first order desulfurizing tower, second level desulfurizing tower and air-introduced machine; Every grade of desulfurizing tower internal structure is identical, the outer a set of identical water spray circulation system of separate connection of tower; Rotary furnace exhanst gas outlet connects the air inlet of first order desulfurizing tower by tracheae, the gas outlet of first order desulfurizing tower connects the air inlet of second level desulfurizing tower by tracheae, and the gas outlet of second level desulfurizing tower connects air-introduced machine by tracheae; Described water spray circulation system is comprised of precipitate and separate pond, water circulating pump and spray head; The collecting tank of first order desulfurizing tower is connected with first order precipitate and separate pond by first order blowdown ditch, and the first order spray head of middle and upper part in first order desulfurizing tower introduced the water in first order precipitate and separate pond by first order water circulating pump by first order shower; The collecting tank of second level desulfurizing tower is connected with precipitate and separate pond, the second level by second level blowdown ditch, and the second level spray head of middle and upper part in the desulfurizing tower of the second level introduced the water in precipitate and separate pond, the second level by second level water circulating pump by second level shower; In described first order precipitate and separate pond and precipitate and separate pond, the second level, all there are water inlet, waterwall and delivery port; Wherein the water inlet in the delivery port in first order precipitate and separate pond and precipitate and separate pond, the second level is communicated with; Gap on waterwall not with water inlet and the same pool side of delivery port; The described first order, second level water circulating pump are controlled by automatic control switch.
In order to save floor occupying area, the tower body design of first order desulfurizing tower of the present invention or second level desulfurizing tower is square-shaped, there is air inlet tower body following side draws the air inlet pipe that connects tower body outside, tower body top is shrunk to taper, the vertex of a cone is exhaust outlet and draws the blast pipe connecing on tower top, tower body bottom is a square collecting tank, and blowdown ditch is arranged at collecting tank bottom.
Compared with the prior art, the present invention, at purifier tail end, is connected with 1 air-introduced machine by tracheae and the outlet of the second desulfurizing tower; This air-introduced machine, under the condition of pipeline that adopts less latus rectum, can guide flowing of flue gas faster, makes it desulfurization rapidly, reaches appliance arrangement installation volume little, the technique effect that desulfurization is fast.The present invention utilizes water curtain to absorb dedusting, in precipitate and separate pond, is provided with waterwall, adopt gap on waterwall not with the ingehious design of intake-outlet with pool side, the design of this waterwall and gap makes the sulphur compound in water obtain better precipitation.Therefore, structure of the present invention can be brought better sedimentation effect in the situation that simple in structure, has possessed outstanding substantive distinguishing features and significant progressive.; That the present invention has is simple in structure, cost is low, easy to operate, the flue gas after this device is processed can directly discharge, free from environmental pollution, the utility efficiency simultaneously reclaiming in tail gas is high.
