Abstract
The utility model discloses a novel low-energy-consumption low-temperature carbide furnace which has the advantages of high waste discharge rate, low energy consumption, safety and the like. The novel low-energy-consumption low-temperature carbide furnace is characterized in that symmetric waste gas discharge holes are formed in two side walls of a furnace body and are capable of better enhancing the efficiency of waste gas discharging; thermal baffles of temperature zones are fixed on the furnace body, so that gaps between the thermal baffles and the furnace body are reduced, and the temperatures of the temperature zones are enabled to be uniform; a fire-resistance insulating material wraps the furnace body, an inert gas conveying pipeline is embedded in a fire-resistant insulating layer, the fire-resistant insulating layer is used for heating gas while keeping the temperature in the furnace without other auxiliary heating devices, and thus the energy consumption is reduced; and balance weight devices are arranged at the two ends of the furnace body, and when expanding at a high temperature, the furnace body is tensioned towards two ends by proper tension generated by the weight balance devices, so that the furnace body does not deform, and the service life of the furnace body is prolonged.
Description
Technical field
The utility model is a kind of carbon fibre producing facility, particularly a kind of low temperature carbonization furnace for carbon fiber production.
Background technology
In carbon fiber was produced, low temperature carbonization furnace was used for the low-temperature carbonization of carbon fiber.Pyrolysis and polycondensation reaction occur in pre-oxygen silk in the low-temperature carbonization process, produce a large amount of accessory substance waste gas and tar.Waste gas is quite serious to the pollution of operation fiber, in time discharge out of the furnace.So waste discharge gas port position seems very important.Existing carbide furnace waste discharge gas port is out that all such waste discharge efficient is low on body of heater side, has a strong impact on steady in a long-termly to produce continuously.
Temperature in the low temperature carbonization furnace stove forms gradient from low to high, for making each warm area temperature controllable, separates with thermal insulation board between warm area.Existing low temperature carbonization furnace thermal insulation board is all to be fixed on refractory insulating layer, between body of heater and warm area thermal insulation board, larger gap is arranged like this, and between warm area, temperature is unstable.
Need inert gas shielding in the carbon fibre carbonizing process, heating is all by auxiliary heating equipment to existing low temperature carbonization furnace to inert gas, has increased energy consumption.
The low-temperature carbonization furnace body is all that heat-resisting alloy steel is made, and produces thermal expansion during high temperature, and the internal stress difference that each thermal treatment zone produces can cause the body of heater irregular deformation, can make whole body of heater distortion when serious.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, provides that a kind of to have waste discharge efficient high, low energy consumption, the low temperature carbonization furnace of the advantage such as security is good.
The utility model is achieved through the following technical solutions:
A kind of low temperature carbonization furnace of Novel low-consumption, the body of heater two side of low temperature carbonization furnace has symmetrical waste discharge gas port; The warm area thermal insulation board is fixed on body of heater, and the inert gas pipeline is embedded in refractory insulating layer, is provided with counter weight device at body of heater two ends.Have symmetrical waste discharge gas port in the two side of body of heater, symmetrical waste discharge mouth can better improve the efficient of waste air, and the quantity of waste discharge gas port is 1 to 3 group; Be divided into a plurality of warm areas in the stove of carbide furnace, the warm area thermal insulation board that is used for each warm area of separation is fixed on body of heater, and with expanding with heat and contract with cold and mobile of body of heater, the warm area thermal insulation board is fixed on body of heater, reduce the gap between warm area thermal insulation board and body of heater, to guarantee that between each warm area, temperature is even; Body of heater outer wrapping flame-proof thermal insulation material, the inert gas pipeline is embedded in refractory insulating layer, and refractory insulating layer heats the inert gas that passes in temperature within keeping stove, does not need other auxiliary heating equipment that gas is heated, to reduce energy consumption; The body of heater two ends of carbide furnace are equipped with the counterweight support, be fixed with pulley on the counterweight support, on pulley around cable wire, cable wire one end is connected on body of heater section flange, the other end is provided with balancing weight, when body of heater at high temperature expands, utilizes counter weight device to produce the suitable pulling force body of heater that stretches to two ends, indeformable to guarantee body of heater, increase the service life.
The beneficial effects of the utility model are:
The waste discharge gas port of the two side symmetry of body of heater has improved the efficient of waste air, has reduced the holdup time of waste gas in body of heater, reduces fiber contamination, has improved quality and the continuous production capacity of producd fibers.The inert gas pipeline is embedded in refractory insulating layer, reduces energy consumption, reduces the device fabrication cost.The body of heater two ends are equipped with counter weight device, when high-temperature furnace body expands, stretch to two ends with suitable pulling force traction body of heater, guarantee that body of heater is indeformable, increase the service life.
