Abstract
The utility model relates to a primary air inlet device of a heat recovery coke oven. The primary air inlet device comprises an air inlet pipeline and a regulating air plate, and is characterized by further comprising a bolt and a nut which are used for articulating the air inlet pipeline with the regulating air plate; the regulating air plate is arranged on a mouth of the air inlet pipeline; and the mouth of the air inlet pipeline is respectively divided into six equal parts by taking the inner diameter of the air inlet pipeline as the reference according to the sequence from the situation that the mouth of the air inlet pipeline is totally closed by the regulating air plate to the situation that the mouth of the air inlet pipeline is totally opened, and a scale groove is manufactured on the mouth of the air inlet pipeline. The primary air inlet device has the advantages of simple structure, convenience in operation, reliability in working, capability of effectively controlling the air inlet volume and the like.
Description
Technical field
The utility model belongs in the coker and installs, and is blast inlet device of a kind of heat recovery coke oven specifically.
Background technology
Heat recovery coke oven is different from conventional vertical coke oven; Its constructional feature has determined unique type of heating; Needed coal gas amount can utilize manual operation to realize when conventional coke oven heated, and control easily fully can be through regulating the purpose to furnace temperature regulating that how much reaches of coal gas amount; And the whole Coking Process of heat recovery coke oven is in negative pressure state all the time, and the coal gas that is produced is directly burning in coke oven, and the coal gas generating capacity alters a great deal with fugitive constituent, furnace temperature and the coking time of mixed coal; Simultaneously in whole process of coking; The generating capacity of coal gas is very unbalanced, therefore can only realize with the required air capacity of control burning, especially in the coking intermediary and later stages; Coal gas is separated out under few situation; If air output can not be effectively controlled, occur air easily at local space and supply with the control imbalance, cause the charge of coke top layerization burnt.
Summary of the invention
The purpose of the utility model is primarily aimed at present heat recovery coke oven because air output can not obtain optimum control and cause the burnt technical problem of charge of coke top layerization; Provide a kind of simple in structure; Easy to operate, reliable operation, and can effectively control blast inlet device of heat recovery coke oven of air input.
The utility model is to address the above problem the technical scheme that adopts:
Blast inlet device of heat recovery coke oven comprises intake stack and regulates aerofoil, it is characterized in that: also comprise hinged intake stack and the screw bolt and nut of regulating aerofoil; Described adjusting aerofoil is arranged on the mouth of intake stack; On the mouth of described intake stack, according to from regulating aerofoil contract fully blast pipe road junction, be as the criterion with the intake stack internal diameter to all opening the blast pipe road junction, be divided into six equal portions respectively and on the blast pipe road junction, make the scale groove.
At pointer of described adjusting aerofoil welding,, on scale card, express the scale of six equal portions at scale card of blast pipe road junction external welding.
The beneficial effect of the utility model is: simple in structure, easy to operate, reliable operation can effectively be controlled air input.Control Jiao on the charge of coke top layer plays fine effect, and through actual motion more than a year, nothing burnt rate in charge of coke top layer is increased to present more than 96% by original 50%, and effect is fairly obvious.
Description of drawings
Fig. 1 is a blast inlet apparatus structure of a heat recovery coke oven synoptic diagram.
Fig. 2 is the air output opening synoptic diagram of a blast inlet device of heat recovery coke oven.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment that is elaborated.
The utility model is that a blast inlet device on the furnace roof of QRD-2000 type heat recovery coke oven improves.As shown in Figure 1, one time the blast inlet device comprises intake stack 1, regulates aerofoil 2 and hinged intake stack 1 and the screw bolt and nut 3 of regulating aerofoil 2; Described adjusting aerofoil 2 is arranged on the mouth of intake stack 1.
As shown in Figure 2, on the mouth of described intake stack 1,, be as the criterion with intake stack 1 internal diameter according to from regulating aerofoil contract fully blast pipe road junction to all opening the blast pipe road junction, be divided into six equal portions respectively, and on the blast pipe road junction, make the scale groove; Perhaps,, on scale card, express the scale of six equal portions at scale card of blast pipe road junction external welding regulating pointer of aerofoil 2 welding.
The utility model application, control Jiao on the charge of coke top layer plays fine effect, and through actual motion more than a year, nothing burnt rate in charge of coke top layer is increased to present more than 96% by original 50%, and effect is fairly obvious.
