Abstract

The utility model discloses an energy-saving open-ring type roasting furnace, which comprises a furnace body including a plurality of furnace chambers and a shared flue duct; each furnace chamber comprises a plurality of electrode boxes, a furnace lid is respectively arranged on each furnace chamber, and a fuel injection hole is formed on each furnace lid; a flame path and a temperature measurement hole are arranged between the electrode boxes; the electrode boxes are respectively 5918mm, 780mm and 6100mm in length, width and height, and the side walls of the electrode boxes are 800mm in thickness; and the top surface of the flame path is arc-shaped. The energy-saving open-ring type roasting furnace increases the production volume and the utilization rate of the box body as well as the holding capacity of the flame path by changing the structural dimension and the shape of the electrode boxes and the flame path; therefore, the time of gas in the flame path is prolonged, the heat energy utilization rate is obviously enhanced, meanwhile, the subsidence and deformation of the flame path during combustion are prevented, and the service life of the furnace body is prolonged.

Description

Energy-conservation unlimited ring-form calcining furnace

Technical field

The utility model relates to a kind of kiln, particularly produces the stoving oven of the plain usefulness of charcoal.

Background technology

Roasting is a very important together technological process in the plain production process of charcoal, its objective is the binding agent coking that makes in the carbon product, gets rid of fugitive constituent, improves its physical strength, electroconductibility and thermotolerance.At present, the stoving oven that charcoal ink factory both domestic and external man generally adopts mostly is circular furnace, the technology relevant with the utility model is to open wide ring-form calcining furnace, its structure is: it comprises the body of heater that is made of a plurality of furnace chambers and common flue, each furnace chamber is made up of a plurality of electrode casees that (so-called electrode case is exactly a casing of placing the plain piece of charcoal, because the plain piece of charcoal is used as electrode, so claim that this casing is the electrode case), furnace chamber is provided with bell, bell is provided with the fuel filling orifice, is provided with quirk and thermometer hole between the electrode case.There are following two defectives in this stoving oven: the one, and electrode case length is generally 4500mm, 800mm, 5200mm, electrode case sidewall thickness is 820mm, because the width and the sidewall thickness of electrode case are all relatively large, conduct heat slower to electrode case center, length is with highly relative less, the electrode tankage is little, and the charcoal prime number amount of splendid attire is few; The 2nd, because the quirk end face is the plane, the distortion of in combustion processes, easily sinking, and also the section of quirk and volume are less, and the time of gas in quirk is short, can't guarantee that the bitumen flue gas that volatilizes fully burns, and the heat energy utilization rate is low.Above-mentioned defective causes that the energy consumption of this stoving oven is higher, output is lower.

The utility model content

The purpose of this utility model is to overcome the existing high deficiency of stoving oven energy consumption, and a kind of energy-conservation unlimited ring-form calcining furnace is provided, and ring-form calcining furnace is opened wide in these environmental protection and energy saving, and not only energy consumption is low, output is high, it is few to reduce discharging thing, and practical, long service life.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises the body of heater that is made of a plurality of furnace chambers and common flue, each furnace chamber is made up of a plurality of electrode casees, furnace chamber is provided with bell, bell is provided with the fuel filling orifice, be provided with quirk and thermometer hole between the electrode case, it is characterized in that, described electrode case long for 5918mm, wide be 780mm, the high 6100mm of being, the sidewall thickness of electrode case is 800mm; Described quirk end face is an arch.

The utility model has the advantages that:

1, the utility model has strengthened length and height owing to dwindled the width of electrode case, makes the size of electrode case adapt to the size of the plain piece of charcoal more, increased output, improved the utilization ratio of casing, a same big kiln adopts the utility model annual production can increase 20-30%.

2, the end face of quirk changes arch into by original plane in the utility model, increased the volume of quirk, prolonged the time of gas in quirk, guaranteed that the bitumen flue gas that volatilizes fully burns, the heat energy utilization rate obviously improves, and on average reduces Sweet natural gas unit consumption 37%-45%.Simultaneously, reduce the discharging few hundred thousand tonnes of waste gas and fine particle, fully realize the effectiveness of energy-conserving and environment-protective, and prevented the sinking distortion of quirk in combustion processes, the work-ing life of having improved body of heater.

3, changed electrode case sidewall thickness in the utility model, improved thermal conductivity, the carbon electrode of the suitable multiple model of roasting has strengthened the practicality of casing.

In a word, the utility model had both increased output by changing the scantlings of the structure shape of electrode case and quirk, had improved the utilization ratio of casing, increased the volume of quirk again, prolonged the time of gas in quirk, the heat energy utilization rate obviously improves, and has prevented the sinking distortion of quirk in combustion processes simultaneously, improved the work-ing life of body of heater, the carbon electrode of the multiple model of roasting that can suit has strengthened the practicality of casing, thereby fully realizes the effectiveness of energy-conserving and environment-protective.
