Abstract
A totally-enclosed direct-current electric arc furnace tail gas smoke tube device comprises a tail gas smoke tube (1) and a reversed-Y-shaped smoke tube (2), wherein the tail gas smoke tube (1) is led out from an electric arc furnace, and the reversed-Y-shaped smoke tube (2) is connected with the tail gas smoke tube (1). An auxiliary breeches pipe (2B) of the reversed-Y-shaped smoke tube (2) is connected with a water cooling system (8). A main breeches pipe (2A) of the reversed-Y-shaped smoke tube (2) is connected with an exhaust gas recycling system (4). A thermocouple (6) is arranged on the main breeches pipe (2A). A flowmeter (7) is arranged on the auxiliary breeches pipe (2B). The totally-enclosed direct-current electric arc furnace tail gas smoke tube device can effectively keep stable pressure in the furnace, quickly reduce temperature of tail gas, ensure smooth recycling of gas, and have the advantages of being simple in structure, stable, reliable and high in titanium slag recycling and tail gas smelting efficiency.
Description
Technical field
The utility model belongs to totally-enclosed direct current furnace titanium slag flue gas during smelting pipeline configuration technical field.
Background technology
The electric furnace of producing at present titanium slag mainly contains three kinds of open type, semi-hermetic type and closeds, and directly discharging is unfavorable for environment after the tail gas simple process that front two kinds of stoves produce; The tail gas that the closed electric furnace produces can be recycled, and improves the utilization rate of the energy, thereby reaches the effect of cost efficiency, but the flue-gas temperature of closed electric furnace is very high, and existing flue technology can not satisfy the requirement of off-gas recovery.
Summary of the invention
The purpose of this utility model provides a kind of totally-enclosed direct current electric arc furnace smelting titanium slag tail gas recycling device in order to overcome the defects that has the electric furnace existence of producing titanium slag now just, this device adopts special smoke pipe to be connected at direct current electric arc furnace and exhaust gas purification system, can successfully reclaim and use titanium slag to smelt the tail gas that produces.
The utility model is achieved by the following technical solution:
A kind of totally-enclosed direct current electric arc furnace tail gas smoke pipe device, the utility model feature is, comprise from electric furnace the tail gas smoke pipe of drawing and the herringbone smoke pipe that is connected with the tail gas smoke pipe, the breeches pipe of paying of herringbone smoke pipe is connected with water cooling system, and main breeches pipe is connected with fume recovery system; Be provided with thermocouple at main breeches pipe, be provided with flowmeter at a pair breeches pipe.
" bow " shape that the main breeches pipe of the utility model herringbone smoke pipe is set to raise up is provided with peep hole at the top of main breeches pipe.
The utility model master breeches pipe is connected by the undulatory bellows of being with of fume recovery system itself with fume recovery system.
The beneficial effects of the utility model are, connect electric furnace and fume recovery system by the herringbone smoke pipe, adopt the water cooling system injected water to the herringbone smoke pipe, can by temperature and the flow of thermocouple and flowmeter monitoring herringbone smoke pipe cooling water, can effectively reclaim the electro-titanium slag smelting exhaust simultaneously; And can effectively keep furnace pressure stable, the temperature of fast reducing tail gas has guaranteed the smooth recovery of coal gas.The utlity model has simple in structure, reliable and stable, the high advantage of recovery titanium slag smelting exhaust efficient.
Below in conjunction with the drawings and specific embodiments the utility model is done further explanation.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
See Fig. 1, a kind of totally-enclosed direct current electric arc furnace tail gas smoke pipe device, the utility model feature are to comprise from electric furnace the tail gas smoke pipe 1 of drawing and the herringbone smoke pipe 2 that is connected with the tail gas smoke pipe, breeches pipe 2 B that pay of herringbone smoke pipe 2 are connected with water cooling system 8, and main breeches pipe 2 A are connected with fume recovery system 4; Be provided with thermocouple 6 at main breeches pipe 2 A, be provided with flowmeter 7 at pair breeches pipe 2 B.
" bow " shape that main breeches pipe 2 A of the utility model herringbone smoke pipe 2 are set to raise up is provided with peep hole 5 at the top of main breeches pipe 2 A.
The utility model master breeches pipe 2 A and fume recovery system 4 are connected by the undulatory bellows 3 of being with of fume recovery system 4 itself.
Operation principle of the present utility model is, when the tail gas that electric furnace 1 produces passes through herringbone smoke pipe 2, because exhaust temperature is higher, need water cooling system 8 injected waters to the cooling layer of paying breeches pipe 2 B inside of herringbone smoke pipe 2, thereby reach the dual purpose of cooling smoke pipe and tail gas, simultaneously can be by thermocouple 6 and the temperature of flowmeter 7 monitoring herringbone smoke pipes 2 cooling layer water and the flow of water.Herringbone smoke pipe 2 tops are provided with peep hole 5, are convenient to observe the tamper whether herringbone smoke pipe 2 stops up and clear up smoke pipe.Flue gas is from smoke pipe 2 to fume recovery system 4, be connected by bellows 3 between smoke pipe and the pipeline, with the extension that the compensation flue causes because of reasons such as variations in temperature, contraction change amount, simultaneously also can limited compensation pipeline radial displacement, and damping vibration is in the propagation of pipe-line system.
