Abstract
The utility model discloses an all-cotton light body structure tunnel kiln for direct reduction iron, which solves the problems that the conventional tunnel kiln is thick and bulky and occupies large areas, the time of drying kilns, and raising and reducing the temperature is long, the kiln body is easy to crack, and the effect of preserving the heat is poor and the like. The all-cotton light body structure tunnel kiln is characterized in that: kiln walls (4) on both sides above slant curve bricks (12) and a kiln crown (9) are made of composite cotton blocks (17) and aluminum silicate fiber cotton blocks (16); only the parts below a kiln car and the slant curve bricks (12) of the whole kiln are constructed by refractory bricks (13); and a U-shaped water tank (8) and a heat exchanger (9) are arranged in a kiln body cooling zone (3). The all-cotton light body structure tunnel kiln has the advantages of energy saving, heat preservation, high economy and applicability, small occupied area and the like, creates higher economic benefit for enterprises due to the popularization and application and is ideal thermal equipment in a metallurgical industry.
Description
One, technical field
The utility model belongs to smelting equipment, relates in particular to the light body structure tunnel cave of a kind of DRI cotton.
Two, background technology
At present, the tunnel cave of producing DRI all is to be made of preheating zone, zone of reduction and salband three part kiln bodies usually, has the advantages such as simple in structure, durable in use, provides convenience for enterprise produces.The problems such as but be generally brick mix structure, have abundant heaviness, floor space is large, and baking kiln, the heating and cooling time is long, is subjected to the impact of rapid heat cycle larger, and the kiln body is easy to crack, and heat insulation effect is relatively poor.
Three, summary of the invention
The purpose of this utility model is for manufacturing enterprise provides a kind of intensification quick, need not to dry by the fire the kiln expense, and floor space is little, affected by rapid heat cycle little, the energy-efficient DRI tunnel cave of the light body structure of the obvious cotton of heat insulation effect.
The technical solution of the utility model is: tunnel cave is that the kiln body that is made of preheating zone, zone of reduction, salband and the outer auxiliary device of kiln etc. consist of, the above both sides Yao Qiang of kiln body introversion envelope brick adopts anchoring piece that composite cotton fabric piece and aluminosilicate fiber cotton piece are installed on the kiln body column, the kiln top is that sheet is hung in employing, suspension hook is installed on the composite cotton fabric piece on the kiln body back timber, and at kiln body inner-wall spraying curing agent, described curing agent must be anti-high temperature about 1400 degree, in case the cotton piece temperature distortion of kiln bluk recombination or come off.In order to save the energy, on kiln body salband, heat exchanger from combustion-supporting hot blast to the zone of reduction burner that carry can be set simultaneously, also can be set to the energy-saving U type water tank that people's productive life provides thermal water resource.
The beneficial effects of the utility model are: owing to using the composite cotton fabric piece high temperature resistant, high insulating effect is saved baking kiln expense, heats up, temperature fall time is short, easy maintenance.Because the composite cotton fabric high insulating effect, body of wall is thin, so floor space is little.At salband heat-exchanger rig and U-shaped water tank are set, realize the residual heat integrative utilization, for enterprise creates larger economic benefit.
The utility model is described in further detail below in conjunction with accompanying drawing.
Four, description of drawings
Fig. 1 is the utility model overall structure horizontal cross-section schematic diagram;
Fig. 2 is the utility model kiln structure transverse sectional view.
Among the figure: 1 is the preheating zone, and 2 is zone of reduction, and 3 is salband, 4 is both sides Yao Qiang, and 5 is track, and 6 is turn-around, 7 is the motorcycle road, and 8 is U-shaped water tank, and 9 is heat exchanger, 10 is kiln body column, and 11 is kiln body back timber, and 12 is bent envelope brick, 13 is refractory brick, and 14 is the burner installing hole, and 15 are the kiln top, 16 is the aluminosilicate fiber cotton piece, and 17 is the composite cotton fabric piece.
Five, the specific embodiment
As shown in Figure 1, outside the kiln body that consists of in the preheating zone 1 of building tunnel cave by laying bricks or stones, zone of reduction 2, salband 3 and the kiln during auxiliary device, at first cleared up ground, lay kiln car track 5, adopt metal material to make kiln body column 10 and kiln body back timber 11 composition kiln body frameworks, then below the bent envelope of kiln body base of frame brick, adopt refractory brick 13 to build the kiln base by laying bricks or stones.Kiln body introversion envelope brick then is to adopt anchoring piece that outer aluminosilicate fiber cotton piece 16 and internal layer composite cotton fabric piece 17 are installed on formation both sides kiln wall 4 on the kiln body column 10 more than 12, sheet is hung in employing, suspension hook is installed on formation kiln top 9 on the kiln body back timber 11 with outer aluminosilicate fiber cotton piece 16 and internal layer composite cotton fabric piece 17, and at kiln body inner-wall spraying curing agent, this fixative is necessary for the sprayed on material of anti-1400 left and right sides high temperature, in case the cotton piece temperature distortion of kiln bluk recombination or come off.In order to save the energy, be provided with heat exchanger 9 from combustion-supporting hot blast to zone of reduction 2 burners 14 that carry at kiln body salband 3, the energy-saving U type water tank 8 of thermal water resource is provided for people's productive life.Enforcement of the present utility model, because full kiln is built into for refractory brick 13 below 12 except kiln car and bent envelope brick, other positions all adopt composite cotton fabric piece and aluminosilicate fiber cotton piece to form, high insulating effect not only, save baking kiln expense, heat up, temperature fall time is short, easy maintenance, and owing to adopting the composite cotton fabric structure, have the advantages such as body of wall is thin, floor space is little.It is applied will for enterprise creates more economic benefit, be the desirable Thermal Equipment of metallurgy industry.
Claims (3)
1. light body structure tunnel cave of DRI cotton, it is to be made of kiln body and the outer auxiliary device of kiln that preheating zone (1), zone of reduction (2), salband (3) consist of, it is characterized in that: the above both sides Yao Qiang (4) of kiln body introversion envelope brick (12) adopts anchoring piece that composite cotton fabric piece (17) and aluminosilicate fiber cotton piece (16) are installed on the kiln body column (10), kiln top (9) is that sheet is hung in employing, suspension hook is installed on the composite cotton fabric piece on the kiln body back timber (11), and at kiln body inner-wall spraying curing agent.
