1.在开采有自燃型单一煤层或多分层煤层时,采用阻化剂溶液防火,向采空区残煤喷射阻化剂溶液,抑制残煤自燃,
是一种有效方法。
2.在煤巷中发生高冒并沉积大量浮煤时,可将自制带孔的铁管插入高冒处,与阻化泵的高压胶管连接,将阻化剂溶液
喷洒在高冒浮煤上,预防自燃发火。
3.向采空区喷射阻化剂气雾,能够取得较好的防火效果,而且经济适用。阻化气雾防火,是将雾化喷头设置在采空区
漏风点,通过液压泵向可移动的雾化喷头供液,向采空区残煤喷射阻化液雾。
SEVERAL APPLICATIONS OF CHEMICAL RESISTANCE PUMP: 1. It is an effective method to prevent spontane
into residual coal in Goaf. 2. When a large amount of floating coal is deposited in the coal roadway,
the self-made iron pipe with holes can be inserted into the high rise place and connected with the
high-pressure rubber pipe of the blocking pump, and the solution of the blocking agent can be sprayed
on the floating coal to prevent spontanetion. 3. Spraying the Goaf with chemical retarder can
achieve better effect of fire prevention and is economical and applicable. In order to prevent fire,
the atomizing nozzle is set at the air leakage point of Goaf, and the liquid is supplied to the movable
atomizing nozzle by hydraulic pump, and the residual coal in Goaf is sprayed with the atomizing liquid.
煤矿用阻化泵特点
1、阻化泵是阻化剂防火技术中的关键设备,随机还配备了必要的管路、过滤器及阀门等系统配件。
2、阻化泵即可用喷枪直接向残煤喷射阻化剂,又可利用于雾化喷头喷雾,还可用于向煤体压注阻化剂。
3、阻化泵体积小、重量轻,运输携带方便,尤其对于井下自然条件较差,设备和人员运行不方便,难以运进较大设备
的地点合适。
4、只需2~3名作业人员,另外配置一辆盛装阻化剂溶液的矿车就可以进行工作。
(阻化剂的选择:阻化剂种类有多种,一般根据具体煤层的阻化率试验结果进行选择。其溶液的浓度、用量及作业时间
、地点等应根据煤层条件(自然倾向性、地质构造、煤层水分、工作面丢煤量、采空区漏风状况等参数)确定,以达
到技术经济效益)
Coal Mine pump features 1, chemical inhibitor pump is the key equipment in the technology of chemical
inhibitor fire prevention, also equipped with the necessary pipeline, filter and valve system
essories. 2. The blocking pump can spray the blocking agent directly to the residual coal with the
spray gun, and can also beed to spray the atomizing nozzle, and can also beed to inject the
blocking agent into the coal. 3. The chemical blocking pump is small in volume, light in weight, easy
to transport and carry, especially for the underground natural condition is poor, equipment and
personnel operation is not convenient, it is difficult to transport into the location of larger
equipment. 4, only 2 ~ 3 workers are needed, and a ore car filled with inhibitor solution can be
equipped to work. (the choice of inhibitor: There are many kinds of inhibitor, generally ording to
the specific coal bed resistance rate test results to choose. The concentration, dosage, working time
and location of the solution should be determined ording to the parameters of coal seam conditions
(natural inclination, geological structure, coal seam moisture, coal amount lost in working face, air
leakage in Goaf, etc.) so as to achieve technical and economic benefits
