具体实施方式Detailed ways

为了对本实用新型的技术特征、目的和效果有更加清楚的理解,现对照附图说明本实用新型的具体实施方式。In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is now described with reference to the accompanying drawings.

如图1、图2所示,本实用新型提出一种高炉煤气喷碱除氯装置100,该喷碱除氯装置100包括有喷碱塔1,喷碱塔1下端设有锥斗8,锥斗底部设有排水装置81;喷碱塔1下部的侧壁上设有进气口11,喷碱塔顶部设有出气口12,该出气口12连接有出气管道121;在喷碱塔1内部且位于进气口11上侧由下向上依序间隔设有喷碱装置2、喷水装置3和填料脱水装置4;所述进气口11连接有进气管道111,进气管道111内设有喷雾装置5。As shown in Figure 1 and Figure 2, the utility model proposes a blast furnace gas alkali spraying chlorine removal device 100, the alkali spraying chlorine removal device 100 includes a spraying alkali tower 1, the lower end of the alkali spraying tower 1 is provided with a cone bucket 8, the cone The bottom of the bucket is provided with a drainage device 81; the side wall of the alkali spray tower 1 bottom is provided with an air inlet 11, and the top of the alkali spray tower is provided with an air outlet 12, and the air outlet 12 is connected with an air outlet pipeline 121; inside the alkali spray tower 1 And be positioned at air inlet 11 upper side and be provided with caustic spraying device 2, water spraying device 3 and filler dehydration device 4 sequentially from bottom to top; There are spraying devices 5 .

由上所述,煤气在进入喷碱塔1之前在进气管道111内先经过喷雾(水雾)装置5加湿、降温,喷雾后的煤气中水分处于饱和状态;煤气从喷碱塔进气口11进入喷碱塔内,气流从下而上,首先经过第一层喷碱装置2对煤气进行喷碱中和处理,由于煤气之前已经加湿、降温,这样可以迅速高效地脱除煤气中的酸性介质(氯离子以及部分硫酸根离子),达到更好的酸碱中和效果。As mentioned above, the coal gas passes through the spray (water mist) device 5 to humidify and cool down in the air intake pipe 111 before entering the alkali spray tower 1, and the moisture in the sprayed coal gas is in a saturated state; 11 Entering the soda spraying tower, the air flow is from bottom to top, firstly through the first layer of soda spraying device 2 to spray soda and neutralize the gas, since the gas has been humidified and cooled before, this can quickly and efficiently remove the acidity in the gas Medium (chloride ions and some sulfate ions) to achieve better acid-base neutralization effect.

在本实施方式中,为保证喷碱的效果,浓碱液需与软水进行混合配比稀释。经过喷碱中和的煤气随即经过第二层喷水装置3,此喷水过程不但可以充分降低煤气的温度,同时还可以吸收煤气中部分酸碱中和液滴。在本实施方式中,在所述喷碱塔1下方设有水池9;第二层喷水装置3可以利用喷碱塔的下部排水循环使用,定期处理即可,大大提高了工业水的重复利用率,同时降低了水耗量。In this embodiment, in order to ensure the effect of alkali spraying, the concentrated alkali solution needs to be mixed with soft water for dilution. The gas neutralized by alkali spraying passes through the second layer of water spraying device 3 immediately. This water spraying process can not only fully reduce the temperature of the gas, but also absorb part of the acid-base neutralization droplets in the gas. In this embodiment, a pool 9 is provided below the soda spraying tower 1; the second layer of water spraying device 3 can be recycled by using the lower part of the soda spraying tower, and it can be treated regularly, which greatly improves the reuse of industrial water rate while reducing water consumption.

为保证第一层喷碱装置2和第二层喷水装置3两层装置的喷淋效果和覆盖面积,喷淋截面不留死角,所述喷淋装置上的喷枪布置需比较均匀。在本实施方式中,所述喷碱装置2、喷水装置3分别由多个环绕喷碱塔1侧壁的喷枪6构成,所述各喷枪6由喷碱塔1外侧贯穿侧壁并指向喷碱塔1中心设置。如图2所示,所述喷枪6包括多个短喷枪61、多个长喷枪62和多个中长度喷枪63;所述多个短喷枪61、多个长喷枪62和多个中长度喷枪63分别环绕喷碱塔1侧壁均匀分布。如图2所示,每层喷枪布置均采用若干根长喷枪62的喷头中心内环布置、中长度喷枪63的喷头中环布置和短喷枪61的喷头外环布置的优化“三环”布置形式,喷碱装置和喷水装置的喷枪布置相同。所述喷枪向下方设置多个喷嘴。In order to ensure the spraying effect and coverage area of the two-layer devices of the first layer of alkali spraying device 2 and the second layer of water spraying device 3, no dead space is left in the spraying section, and the arrangement of the spray guns on the spraying device needs to be relatively uniform. In this embodiment, the alkali spraying device 2 and the water spraying device 3 are respectively composed of a plurality of spray guns 6 surrounding the side wall of the alkali spray tower 1. Each of the spray guns 6 penetrates the side wall from the outside of the alkali spray tower 1 and points to the Alkali tower 1 is set in the center. As shown in Figure 2, described spray gun 6 comprises a plurality of short spray guns 61, a plurality of long spray guns 62 and a plurality of medium-length spray guns 63; They are evenly distributed around the side wall of the alkali spray tower 1 respectively. As shown in Figure 2, the arrangement of each layer of spray guns adopts the optimized "three-ring" arrangement of several long spray guns 62 in the center inner ring of spray heads, middle length spray guns 63 in the middle ring of spray heads, and short spray guns 61 in the outer ring of spray heads. The spray guns of the caustic spraying device and the water spraying device are arranged in the same way. The spray gun is provided with a plurality of nozzles downward.

煤气经过两层喷淋后,气体中机械水含量比较高,需要对煤气进行脱水处理。如图1所示,煤气从下往上,通过填料脱水装置4,煤气中的小水滴经过花环填料后,汇聚成大颗粒利用重力原理进行脱水。After the gas has been sprayed in two layers, the mechanical water content in the gas is relatively high, and the gas needs to be dehydrated. As shown in Figure 1, the gas passes through the packing dehydration device 4 from bottom to top. After the small water droplets in the gas pass through the garland packing, they converge into large particles and are dehydrated by the principle of gravity.

在本实施方式中,在所述填料脱水装置4的上方还设有填料冲洗装置7;所述填料冲洗装置7由环形喷枪构成。主要是考虑系统长时间运行,填料易结垢堵塞,造成系统压力损失过大,需要定期用高压水进行喷淋冲洗。In this embodiment, a filler flushing device 7 is further provided above the filler dehydration device 4; the filler flushing device 7 is composed of an annular spray gun. The main reason is that the system runs for a long time, and the packing is easy to scale and block, which will cause excessive pressure loss in the system, and it needs to be sprayed and flushed with high-pressure water regularly.

在喷碱塔1顶部出气管道121上且临近出气口12的位置设有放散阀122;当煤气压力过高时,自动打开放散;正常压力时,则处于关闭状态。主要是为防止高压时煤气从喷碱塔底部的排水装置81中窜出,出现安全事故。On the gas outlet pipe 121 at the top of the alkali spray tower 1 and near the gas outlet 12, a release valve 122 is provided; when the gas pressure is too high, it will be automatically opened and released; when the gas pressure is normal, it will be in a closed state. Mainly in order to prevent gas from spewing out from the drainage device 81 at the bottom of the soda spraying tower during high pressure, causing safety accidents.
