The objective of the invention is, design a kind of air bath type slag cooling machine, its no rotating mechanism and make the runnability height reliable, and power consumption is low, volume is little, is easy to realize mechanization, automation and the maximization of lime-ash cooling.
Technical scheme of the present invention is, described air bath type slag cooling machine organic frame and shell, cover top portion is provided with top cover, its design feature is, relative horizontal plane be housed be parallel in the frame or the higher other end of an end is lower and with the angle β of horizontal plane be 0-8 ° horizontal or tilting air drain pad, the width of described shell is 2-20 a times of this air drain pad width, the length of described air drain pad is 4-40 times of its width, it is that the aperture of 5-15% and the diameter of described aperture are the 2-8 millimeter that percent opening is arranged on the described air drain pad, air drain pad below is that the air compartment and the described air compartment that are provided with inlet of cold air can be divided into 1-8 along air drain pad length direction, the warm sludge inlet tube is located at described shell one end and is positioned at air drain bed hedgehopping end top, build air drain pad both sides the air drain brick, hot air outlet is located at shell and holds top in addition, be positioned at air drain pad low side top on the shell and be provided with residue outlet and accident scum pipe, the cooling water pipe assembly is housed in the described shell and the air drain cover is equipped with in its top.
Below the present invention made further specify.
Referring to Fig. 1 and Fig. 2, air bath type slag cooling machine organic frame of the present invention (1) and shell (17), shell (17) top is provided with top cover (9), its design feature is, relative horizontal plane be housed be parallel in the frame (1) or the higher other end of an end is lower and with the angle β of horizontal plane be 0-8 ° horizontal or tilting air drain pad (12) (referring to Fig. 1 and Fig. 3), the width of described shell (17) is 2-20 times (promptly being) of air drain pad (12) width referring to width shown in Figure 2, the length of described air drain pad (12) is 4-40 times of its width, even more; It is that aperture and the described hole diameter of 5-15% is the 2-8 millimeter that percent opening is arranged on the described air drain pad (12), and air drain pad (12) below is the air compartment (16) that is provided with inlet of cold air (18), and air compartment can be divided into 1-8 along air drain pad (12) length direction; Warm sludge inlet tube (4) is located at shell (17) one ends and is positioned at the high-end top of air drain pad (12) (referring to Fig. 1); There is air drain brick (13) (referring to Fig. 2, Fig. 4) air drain pad (12) both sides, and it highly can be the 50-300 millimeter; Hot air outlet (6) is located at shell (17) and holds the top in addition, be positioned at air drain pad (12) low side top on the shell (17) and be provided with residue outlet (8) and accident scum pipe (19), cooling water pipe assembly (5) (referring to Fig. 1, Fig. 2) is housed in the shell (17) and air drain cover (10) (referring to Fig. 2) is equipped with in its top.Also can sealing plate (15) be set, can post thin slice brick (14) on this plate (15), in order to the outer casing space of air drain pad (12) top and the sealing between the following side space at described air drain brick (13) side (referring to Fig. 2).Also can fire door (3) be set, and can manhole door (7) be set, in order to observing and safeguarding in shell (17) at shell (17) one ends.
In the present invention, the cooling water pipe assembly can adopt finned prior art structure, cylinder iron economize gas pipe as boiler, its installation should parallel with air drain pad (12) and should be advisable greater than 250 millimeters apart from the height of air drain pad (12) in its lower edge, to make it to steep in the material flow of air drain both sides as far as possible, shell (17) inner surface region of interest can be covered heat-resistant antifriction coating or build and go up refractory brick.
Operation principle of the present invention is, the warm sludge that boiler is discharged is sent in the cold slag machine by described warm sludge inlet tube (4), air drain pad (12) bottom air compartment (16) has the cold wind of being sent into by inlet of cold air (18), the described aperture of described cold wind on air drain pad (12) upwards blows out, by the air drain brick (13) of described air drain pad (12) and both sides become the space to form air drain, warm sludge upwards blows afloat in this air drain, and fall to both sides, (through oblique stockpile or tilting sealing plate) falls after rise to air drain, blown afloat again, shuttling movement contacts with cooling water pipe assembly (5) and to produce heat exchange and realize enhanced heat exchange, and lime-ash obtains cooling; In view of the length of air drain pad much larger than its width, but along air drain pad length direction formation temperature gradient, make material can be cooled to desired low temperature; Cold wind is also taken away the part heat simultaneously; Cooled lime-ash is discharged by residue outlet (8) at last.Be in operation and meet that especially big particle enters air drain and when influencing air drain and normally moving, can open accident scum pipe (19) and discharge.
As known from the above, the present invention is a kind of air bath type slag cooling machine, and it does not have mechanical running gear and operation troubles is few, reliability is fabulous; And its good cooling results, volume are little, arrange not limited by the place, and be convenient, flexible, be easy to maximize; Also recyclable physical heat of ash dregs can be beneficial to the improvement condition, improve boiler thermal output; Can reduce power consumption; No dust pollution during the device sealing can be classified environmental protection equipment as; Tapping temperature is low and be dry-type slag cooling, does not destroy the activity of slag, is beneficial to ash comprehensive utilization.
