D88尊龙焦爐煤氣發電機組做為焦化使用的特點

D88尊龙焦爐煤氣是焦化工業的首要副產品之一,每煉一噸焦炭會產出300-350m3左右的焦爐煤氣,焦爐煤氣約40%-50%用于回爐燃燒,其余剩余煤氣有必要運用專門回收設備進行回收運用,否則只能燃燒排放大氣。一些小的企業,由于煉焦發作的焦爐煤氣量較少,出資甲醇、化肥等其他項目或許還達不到規劃,成本優勢不明顯,因此用于焦爐煤氣發電是一種出資小、見效快的一種有效途徑。

Coke oven gas is one of the primary by-products of the coking industry. Each ton of coke produced about 300-350m3 of coke oven gas. About 40-50% of coke oven gas is used for back-burning. It is necessary to use special recovery equipment to recover the remaining gas, otherwise it can only burn and discharge the atmosphere. Some small enterprises, due to the small amount of coke oven gas in coke oven, investing in methanol, fertilizer and other projects may not reach the planning, the cost advantage is not obvious, so the use of coke oven gas for power generation is an effective way with small investment and quick effect.

2. 內燃式焦爐煤氣發電機組的功能特征

D88尊龙2. Functional Characteristics of Internal Combustion Coke Oven Gas Generator Unit

焦爐煤氣內燃機發電機組的作業原理與轎車發動機作業原理類似,需要用火花塞燃燒,由于內燃機汽缸內作業溫度抵達14000?使其功率大大超過了蒸汽輪機和燃氣輪機,發電功率抵達35%以上。其特征為:

The working principle of coke oven gas internal combustion engine generator set is similar to that of car engine. It needs to be burned with spark plug. Because the working temperature in the cylinder of internal combustion engine reaches 14000, its power greatly exceeds that of steam turbine and gas turbine, and its power generation reaches more than 35%. Its characteristics are as follows:

2.1結構緊湊,體積小占地少。

2.1 Compact structure, small size and small occupation of land.

D88尊龙2.2熱功率高,相比較蒸汽輪機和燃氣輪機高10%以上。

2.2 High thermal power, 10% higher than steam and gas turbines.

2.3操作簡潔,起動方便。

D88尊龙2.3 The operation is simple and easy to start.

2.4規劃可選擇規模較寬,幾臺或十幾臺并機均可。

2.4 Planning can choose a wider scale, several or more machines can be combined.

D88尊龙2.5由于工藝簡略,出資較少可進行主動化控制。

2.5 Because of the simplicity of the process, less investment can be made to carry out active control.

網停電時發電機所發電力反送入市電電網構成事故。

3.2 A set of equipment reverse power maintenance module at the low-voltage main switch of the main distribution room can prevent the power generated by the generator from being sent back to the municipal power grid when the power outage occurs.

3.3當外網停電時,低壓總開關通過逆功率模塊控制斷路器跳開,發電機變成孤網工作,確保風機、循環氨水泵等首要設備不斷電而正常工作;可避免焦爐因停風機而發作的煙火污染,如功率足夠大也可確保焦爐的正常生產。

3.3 When the power outage occurs in the external network, the low-voltage main switch controls the breaker to jump off through the inverse power module, and the generator turns into an isolated network to ensure that the primary equipment such as fans and circulating ammonia water pumps are continuously powered up and working normally. It can avoid the pyrotechnic pollution caused by the blower outage in the coke oven, and ensure the normal production of the coke oven if the power is large enough.

D88尊龙3.4當外網再次供電時,可通過總開關處同期設備再次并網繼續工作。

3.4 When the external network is powered again, it can be connected to the grid again through the same period of equipment at the main switch.

D88尊龙3.5發電機組可通過程控機軟件實時監控發電機組的各種溫度、壓力、電壓、電流等參數和主動調理煤氣、冷卻水等流量,確保發電機組的正常工作

3.5 The parameters of temperature, pressure, voltage and current and the flow of gas and cooling water can be monitored in real time by the program-controlled computer software to ensure the normal operation of the generating unit.

4.定論

4. conclusion

關于焦化企業來講,任何時刻停電都將構成巨大的丟掉,一旦停電,焦爐上升管因壓力過高,焦爐荒煤氣逸出,均需翻開放散管放散而構成焦爐爐頂濃煙滾滾,環保方面是不允許的;別的由于焦爐爐體內荒煤氣無法導出,壓力過高會構成內部串漏對爐體的損害也很大,循環氨水間斷循環也會給煤氣冷卻和焦油導出構成極大困難;由此可見,采用雙回路不間斷供電對企業來講是至關重要的。

As far as coking enterprises are concerned, blackouts at any time will constitute a huge loss. Once blackouts occur, the riser of coke oven will cause excessive pressure and the waste gas of coke oven will escape. It is necessary to turn over and open the loose pipe to dissipate the heavy smoke on the top of coke oven, which is not allowed in environmental protection. Otherwise, because the waste gas in the coke oven can not be exported, excessive pressure will cause serious damage to the furnace. Intermittent circulation of circulating ammonia water also poses great difficulties for gas cooling and tar export. Thus, it is very important for enterprises to adopt double-loop uninterrupted power supply.

運用焦爐充裕煤氣發電,一能處理焦化企業供電確保問題;二能在節能減排的一起還可以發明經濟效益,較好的處理了煤氣浪費、污染環境和外購電能的對立。而且焦爐煤氣發電技能老練,出資少見效快,是中小型焦化在運用較少資金能夠取得許多方面收益的一種有效途徑,也對緩解我國動力嚴重具有重要意義。

Utilizing coke oven gas to generate electricity can not only deal with the problem of ensuring power supply in coking enterprises, but also create economic benefits with energy saving and emission reduction, which can better deal with the opposition of gas waste, environmental pollution and purchased electric energy. Moreover, the sophisticated coke oven gas power generation skills, less investment and quick results, is an effective way for small and medium-sized coking in the use of less funds to achieve many benefits, but also to ease the power of our country is of great significance.
