Abstract
The utility model provides a waste heat utilization device of a coke oven gas, relates to a waste heat treatment device of the coke oven gas, and aims to solve the problem that a great amount of heat quantity cannot be used when the coke oven gas overflows. The waste heat utilization device of the coke oven gas comprises a recuperative furnace, wherein the recuperative furnace is provided with a discharge port in the bottom and a gas outlet in the top, an extrusion agglomerating machine is further arranged at the discharge port, and a gas pipeline which is further communicated with the side wall close to the discharge port is communicated with a coke oven; and a coal feeding port is further formed in the upper part of the recuperative furnace, and a plurality of guide plates are arranged on the two side walls of the recuperative furnace in a staggered manner. With the adoption of the waste heat utilization device of the coke oven gas, the coal is sufficiently contacted with the coke oven gas when passing the recuperative furnace, and absorbs heat quantity carried by the coal gas, so that the coal is sufficiently heated; and simultaneously, tar oil in the coke oven gas further can be absorbed during a heating process, so that the coal further has a certain cohesiveness, the coal can be manufactured into hot-press coal briquettes when the preheated coal with a certain cohesiveness passes through the extrusion agglomerating machine again, and the waste heat of the coke oven gas and the tar oil carried by the waste heat are effectively utilized.
Description
Technical field
The utility model relates to a kind of coke-oven gas Heat Treatment device, specifically a kind of coke-oven gas residual heat using device.
Background technology
Coke oven produces coke-oven gas in the process of carrying out coking with coal, coke-oven gas contains the heat of 700 ℃～800 ℃ of temperature when overflow on coke oven top.Current this part heat does not also have the effectively Perfected process of utilization.Yet coke-oven gas must spray again ammoniacal liquor and cool off before entering gas purification and changing the product system, causes this part heat can't obtain utilizing and wasting.
The utility model content
The purpose of this utility model is to provide a kind of coke-oven gas residual heat using device, solves to contain the unserviceable problem of amount of heat when coke-oven gas overflows.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of coke-oven gas residual heat using device, it is characterized in that, comprise recuperative furnace, the recuperative furnace bottom is provided with discharge port, the top is provided with the air outlet, also be provided with the extruding agglomeration machine at the discharge port place, communicating with coke oven near also being communicated with gas line on the sidewall at discharge port place; The top of recuperative furnace also is provided with coal filling hole, staggeredly on the two side of recuperative furnace is provided with a plurality of guide plates.
The guide plate level is fixed, and is provided with the refractory materials skewback on the top of guide plate and contact position, recuperative furnace furnace wall.
It is skewed that guide plate is, and a unsettled end tilts to recuperative furnace discharge port place.
The beneficial effects of the utility model are: coal fully contacts with coke-oven gas by recuperative furnace the time, absorb the heat that coal gas carries, coal is fully heated, in heating and process, can also absorb simultaneously the tar in the coke-oven gas, make coal have again certain cohesiveness, when by preheating with have certain close-burning coal and during agglomeration machine, just can be made into the hot pressing coal cinder by extruding again, the waste heat of coke-oven gas and its tar that carries all are utilized effectively.
Description of drawings
Fig. 1 is structure diagram of the present utility model.
Among the figure: 1 recuperative furnace, 2 discharge ports, 3 air outlets, 4 extruding agglomeration machines, 5 gas lines, 6 coke ovens, 7 coal filling holes, 8 guide plates.
Embodiment
As shown in Figure 1, a kind of coke-oven gas residual heat using device comprises recuperative furnace 1, recuperative furnace 1 bottom is provided with discharge port 2, the top is provided with air outlet 3, also is provided with extruding agglomeration machine 4 at discharge port 2 places, is communicating with coke oven 6 near also being communicated with gas line 5 on the sidewall at discharge port 2 places; The top of recuperative furnace 1 also is provided with coal filling hole 7, staggeredly on the two side of recuperative furnace 1 is provided with a plurality of guide plates 8.
The coal gas that overflows from coke oven 6 enters recuperative furnace 1 bottom by gas line 5, coal charge enters in the stove by the top of coal filling hole 7 from recuperative furnace 1, the coal charge that enters forms a S route and enters extruding agglomeration machine 4 rear extruding formation hot pressing coal cinders by discharge port 2 under the effect of guide plate 8.In the process that coal charge falls, coal charge fully contacts under the effect of guide plate 8 and contains the coal gas of high calorie, thereby obtains preheating, owing to also contain tar in the coal gas, coal charge has certain cohesiveness after absorbing tar, more is beneficial to extrusion molding.To adopt horizontally disposed guide plate 8, form coal charge in the place that guide plate 8 contacts with recuperative furnace 1 furnace wall easily and pile up, in order addressing this problem, can be provided with herein a refractory materials skewback, make things convenient for like this whereabouts of coal charge.For addressing this problem, can also adopt skewed guide plate 8 is set, make the unsettled end of guide plate 8 to the bottom angled of recuperative furnace 1, avoid occurring coal charge and pile up.
