Description

A kind of leap pore structure of adjustable coke oven heating level

Technical field

Horizontal the utility model relates to coke oven heating Level tune technical field more particularly to a kind of adjustable coke oven heating Across pore structure.

Background technique

Heat levels are a significant dimensions in coking furnace shaft structure.Heat levels are too small, carbonization chamber headspace temperature Height is spent, the quality and yield of raisingization product are unfavorable for, also will increase roof carbon generation；Heat levels are too big, can reduce Top charge of coke temperature influences charge of coke uniformly ripening up and down.Currently, most of is being preset parameter with the heat levels of coke oven, it is real In the production process of border coke quality can only be improved by modes such as adjustment criteria fire path temperatures.

7.63 meters of tops that German Wood Company is designed and developed fill coke oven, have it is adjustable cross over hole, across hole point up and down 2 Layer design is mainly used for adjusting heat levels and furnace roof space temperature, guarantees that top charge of coke is mature.Its heat levels, which is adjusted, to be used Adjusting brick be the sliding brick of horizontal movable type, but slide brick to quantify regulation performance poor, cause degree of regulation not high.

Summary of the invention

The utility model provides a kind of leap pore structure of adjustable coke oven heating level, by rotatable adjusting brick, The heat levels that coking furnace shaft can accurately be adjusted adjust the height of furnace roof to Temperature Distribution and oven top of coke oven space temperature, thus So that coking furnace shaft is can adapt to the variation of different coal charges, preferably control the temperature of coke oven standard flue, improves coke oven thermal effect Rate.

In order to achieve the above object, the utility model is implemented with the following technical solutions:

A kind of leap pore structure of adjustable coke oven heating level, combustion chamber are made of multiple duplex flues, form duplex Be connected to respectively by upper and lower 2 layers across hole at the top of the flue of flue, upper layer across hole and lower layer across set between hole every Wall, each flue top are equipped with peephole；Adjusting brick seat is set respectively in the airflow channel of two sides at the top of the partition wall, is adjusted Adjusting brick is equipped in brick seat；Adjusting brick can be closed after horizontally rotating by the throughhole portions in adjusting brick seat or all, thus will Corresponding airflow channel part or all closing；Adjusting brick realizes that rotation is adjusted by the adjusting rod protruded into from peephole.

Vertical through-hole is set in the middle part of the adjusting brick seat, and groove is set at the top of through-hole for placing adjusting brick；Groove with The cross sectional shape of lower through-hole is the narrow dumbbell shape in the wide centre in both ends；The cross section of adjusting brick is opposite with the through hole section shape The dumbbell shape answered；The both ends load of adjusting brick is located on the groove of via top, and integral level can be rotated on groove surface； When the both ends of adjusting brick are overlapped with the both ends of through-hole, through-hole is all closed；When adjusting brick both ends line and through-hole two When head line is vertical, the opening area of through-hole is maximum.

The adjusting rod is made of the body of rod and front fork, front fork have 2 extensions, respectively with corresponding adjusting brick on both sides of the middle 2 recess contacts carry out rotation adjusting.

Compared with prior art, the utility model has the beneficial effects that

By rotatable adjusting brick, the heat levels of coking furnace shaft can be accurately adjusted, adjust the high Xiang Wendu of furnace roof Distribution and oven top of coke oven space temperature preferably control coke oven mark so that coking furnace shaft be made to can adapt to the variation of different coal charges The temperature of quasi- flue improves the coke oven thermal efficiency.

Specific embodiment

Specific embodiment of the present utility model is described further with reference to the accompanying drawing:

As shown in Figure 1, a kind of leap pore structure of adjustable coke oven heating level described in the utility model, combustion chamber is by multiple Duplex flue 1 forms, and forms and is connected to respectively by upper and lower 2 layers across hole 2,3 at the top of the flue of duplex flue 1, upper layer Across hole 2 and lower layer across partition wall 4 is set between hole 3, peephole 6 is equipped with above each flue；The 4 top two sides of partition wall Airflow channel in set adjusting brick seat 5 respectively, adjusting brick 7 is equipped in adjusting brick seat 5；Adjusting brick 7 can will be adjusted after horizontally rotating The throughhole portions or all closings in brick seat 5 are saved, thus will corresponding airflow channel part or all closings；Adjusting brick 7 passes through certainly The adjusting rod 8 that peephole 6 protrudes into realizes that rotation is adjusted.

As shown in Fig. 2 a-2c, Fig. 3 a-3b, the middle part of the adjusting brick seat 5 sets vertical through-hole 52, the top of through-hole 52 If groove 51 is for placing adjusting brick 7；The dumbbell shape narrow as the wide centre in both ends using the cross sectional shape of lower through-hole 52 of groove 51；It adjusts The cross section for saving brick 7 is dumbbell shape corresponding with 52 cross sectional shape of through-hole；The both ends load of adjusting brick 7 is located at the top of through-hole 52 On the groove 51 in portion, and integral level it can be rotated on 51 face of groove；When the both ends of adjusting brick 7 are overlapped with the both ends of through-hole 52 When, through-hole 52 is all closed；When the both ends line of adjusting brick 7 is vertical with the both ends line of through-hole 52, the opening of through-hole 52 Area is maximum.

As shown in fig. 6, the adjusting rod 8 is made of the body of rod and front fork, front fork has 2 extensions, adjusts respectively with corresponding 2 recess contacts of section 7 on both sides of the middle of brick carry out rotation adjusting.

A kind of leap pore structure of adjustable coke oven heating level described in the utility model in the application, when discovery oven top of coke oven It when space temperature is excessively high, needs to increase the heat levels of coking furnace shaft, only uses lower layer at this time across hole 3；Specific practice be by The self-corresponding peephole 6 of adjusting rod 8 protrudes into flue, rotates adjusting brick 7, makes adjusting brick 7 by the through-hole 52 on adjusting brick seat 5 All closing (as illustrated in figs. 5 a-5 c) has sealed air-flow after 2 airflow channels when 1 two sides of duplex flue all seal The path in hole 2 is crossed over towards upper layer, to reach the mesh for increasing coking furnace shaft heat levels by shortening waste gas circulation path 's.

Conversely, when finding that furnace roof space temperature is relatively low, it is desirable to reduce the heat levels of coking furnace shaft need to make gas at this time Stream crosses over hole 2 by upper layer, and specific practice is adjusted by adjusting brick 7 of the adjusting rod 8 to upper layer across 2 two sides of hole, makes Adjusting brick 7 exposes the partial through holes 52 on adjusting brick seat 5 after rotating, when 2 airflow channels of 1 two sides of duplex flue are all beaten After opening (as depicted in figure 4 a-4 c), that is, the path that air-flow crosses over hole 2 towards upper layer is opened, thus by lengthening waste gas circulation road Diameter achievees the purpose that reduce coking furnace shaft heat levels.

Through-hole 52 on adjusting brick seat 5 is opened or closing area can be adjusted as needed, so that reaching accurate adjusts coke The purpose of stove heating level.

The adjusting brick 7 and adjusting brick brick cup 5 are preferably but not limited to apply glaze clay brick.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
