Description
Technical field
The utility model relates to a kind of member of coker, especially a kind of dried chute district bracket that puts out stove.
Background technology
Dry Quenching Technology can be produced middle and high pressure superheated vapour by the red burnt sensible heat of efficient recovery, the discharge of steam of having avoided containing phenol, prussiate, sulfide and dust in the wet quenching process pollutes, the cold and hot index of STRENGTH ON COKE is improved the aspect simultaneously active effect, country classifies this technology as introduction, the streamlined technological project that digests, absorbs, domesticizes, and is supported in coking industry and promotes on policy.
The dried stove that puts out is crucial equipment in Dry Quenching Technology, and the dried stove internal upper part that puts out is the chamber and be looped around the annular passage outdoor and that is communicated with the chamber of prestoring that prestores of prestoring, and the bottom is a cooling room, the chute district connection by the middle part between upper, annular air channel and the bottom cooling room.
The chute district is as the structure of forming a connecting link, its member mainly comprises bracket, chute masonry, the chute masonry connects the outer walling of annular passage and cooling room masonry and body of heater is sealed, bracket is arranged on the brickwork construction in the stove, its bottom is supported by the cooling room masonry, the outer walling of its top braces annular passage and interior walling, the outside embed in the chute masonry and with the chute differentiation and are divided into a plurality of independently chutes.
Therefore, bracket belongs to main supporting structure, and be positioned at the impact that main heat exchange area need be born red Jiao, belong to damageable zone, the cracking and the fracture of bracket brick very easily appear, can cause the whole dried furnace interior that puts out to cave in when serious, change bracket brick mode of operation general using chute cuff and do support with lower edge, the chamber interface faulting of slab ends that prestores, carry out furred ceiling, impaired bracket both sides are supported respectively, carried out single replacing then, servicing time is long, difficulty is big, the expense height, and it is not good to repair the back result of use, and to put out in the stove other positions damages serious to dried for shutdown maintenance simultaneously.
The utility model content
In order to overcome existing deficiency, technical problem to be solved in the utility model provides a kind of chute district bracket of ftractureing, rupture, caving in can avoided.
The technical scheme that its technical problem that solves the utility model adopts is: the dried chute district bracket that puts out stove, the interior walling of body of heater supports by bracket, the bracket bottom is supported by the cooling room masonry, and described bracket is a metalwork, and the bracket surface coverage has thermofin and wearing layer.
The beneficial effects of the utility model are: the metalwork bracket is isolated red Jiao's thermal shocking by thermofin, avoid the wearing and tearing of red Jiao by wearing layer to metalwork, and compare with existing fire-resistant brick bracket, the bracket structure intensity of metalwork is higher, can avoid ftractureing, rupturing, cave in, the work-ing life that can postpone bracket, and prolonged dried putting out the stove shutdown maintenance cycle, and because the bracket intensity height of metalwork, can be by reducing bracket quantity, thereby increase chute district channel outlet area, reduce the gas communication resistance, optimize the dried technic index in the stove of putting out.
For walling in guaranteeing and bracket stability in contact, can be evenly distributed on all brackets walling in described bracket supports by ring washer simultaneously with stressed.Simultaneously,, bracket is changed, changed job safety, convenience owing to after annular backing ring makes bracket evenly stressed, can mend the method for technology by replacing a damaged part by being similar to coke oven.
In order further to control the temperature of bracket structure, avoid metal generation hot mastication, distortion etc., described bracket is provided with cooling water pipeline, and described ring washer is provided with cooling water pipeline.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the part of the B-B sectional view of Fig. 1;
Fig. 3 is the a-quadrant enlarged view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2, shown in Figure 3, the dried stove internal upper part that puts out is the chamber 1 and be looped around the annular passage 5 outdoor and that be communicated with the chamber 1 that prestores that prestores of prestoring, and the bottom is a cooling room 4, and the chute district by the middle part between upper, annular air channel 5 and the bottom cooling room 4 is communicated with.The chute district is as the structure of forming a connecting link, comprise bracket 3, chute masonry 6, chute masonry 6 connects the outer walling 52 of annular passages 5 and cooling room masonry 42 and with the body of heater sealing, bracket 3 supports superstructure along the body of heater circumference uniform distribution, and chute distinguished is divided into a plurality of independently chutes.
Red Jiao is dropped in the stove by distribution device, chamber 1 enters cooling room 4 through annular passage 5 by chute from prestoring, rare gas element is sent into from bottom of furnace body, by cooling room 4 by entering annular passage 5 behind the chute, discharge from annular passage outlet 53, thereby rare gas element is realized quenching with red burnt generation heat exchange in the process of circulation.
The dried chute district bracket that puts out stove of the present utility model, the interior walling 51 of body of heater supports by bracket 3, and bracket 3 bottoms are supported by cooling room masonry 42, and described bracket 3 is metalworks, and bracket 3 surface coverage have thermofin and wearing layer.
Under the prerequisite that guarantees bracket 3 support strengths, in order to alleviate the deadweight of bracket 3 itself, described metalwork is a metal framework structure, and its cavity part is filled by brick structures.Concrete, adapt with chute district shape, metal framework structure is inverted trilateral, the interior brace 32 and the outer brace 33 that comprise interconnective top, horizontal bar 31, both sides, between interior walling 51, outer walling 52, interior walling 51 and the outer walling 52 between chute masonry 54 support by horizon bar 31, horizon bar 31 is embedded in the masonry, and outer brace 33 is embedded in the chute masonry 6, and interior brace 32 links to each other with outer brace 33 and supports by cooling room masonry 42.Here inside and outside all with respect to inside and outside the body of heater.
Because bracket 3 is to be provided with at interval,, can be evenly distributed on all brackets 3 walling 51 in described bracket 3 supports by ring washer 2 simultaneously for walling in guaranteeing 51 and bracket 3 stability in contact with stressed.Simultaneously,, bracket 3 is changed, changed job safety, convenience owing to after annular backing ring 2 makes bracket 3 evenly stressed, can mend the method for technology by replacing a damaged part by being similar to coke oven.
And assembling, inspection, the maintenance of ring washer 2 for convenience, described ring washer 2 is sectionally assembled.
