Description
Technical Field
The invention relates to the technical field of blasting initiating explosive devices, in particular to a safe detonation method and device for NHN initiating explosive.
Background
The application of the current initiating explosive in the initiating equipment industry NHN (namely nickel hydrazine nitrate) is expanded year by year, and the current mainstream DDNP initiating explosive is replaced. With the increasing production application of NHN detonator products, more and more process waste explosive (needing to be subjected to pin blasting treatment) is generated in the production process of the products, and the production safety risk brought by the process waste explosive is higher.
For the pin blasting of NHN initiating explosive, the pin blasting method adopted by most of the current production enterprises is a chemical decomposition method, the pin blasting method is relatively thorough, the single pin blasting amount is limited, the dosage of chemical reagents such as strong acid and the like in the pin blasting process is large, nickel ions in subsequent pin blasting wastewater exceed the standard, and the treatment cost is high;
for example, using a chemical decomposition process, such as the pin-blasting of 1kg of NHN primer, 5l of dilute nitric acid is required to produce about 20l of wastewater. Wherein the cost of the nitric acid is about 5 yuan, the cost of the 20L wastewater treatment is about 26 yuan, the cost is about 31 yuan approximately, 1kg of NHN initiating explosive needs to be sold and exploded, 1L of diesel oil and 0.5L of alcohol are consumed, and the treatment cost is about 7 yuan.
In addition, the Chinese patent application No. 200410040167.7 entitled "a method and a device for destroying waste detonators" discloses a method for destroying waste detonators, which comprises the steps of soaking the waste detonators in engine oil or diesel oil, and completely soaking and passivating the primary explosive and the high explosive contained in the waste detonators to lose the explosive property;
however, the method is to process a semi-finished detonator product, wherein the primary explosive agent is in a shape of a closed chamber block in the pipe body, and the contact part with diesel oil is only provided with a round hole with the diameter of 2.0mm, so the soaking passivation effect is poor, and the soaking time is long; furthermore, the person skilled in the art is familiar with: the basic detonator (explosive column tube) which is not filled with the initiating explosive is processed, and then the basic detonator can be destroyed by adopting a passivation burning method, and the basic detonator which is filled with the initiating explosive is destroyed by adopting a blasting method, because the initiating explosive can be completely passivated by diesel oil under the condition of compaction, the detonation can be easily caused during combustion destruction. In addition, more importantly, the application time of the patent is 2004, but as well known by those skilled in the art, the NHN initiating explosive is popularized and used after 2008, that is, the method is to carry out pin blasting on a detonator, is not directed to the NHN initiating explosive or is not suitable for the NHN initiating explosive, and has long pin blasting time and low efficiency.
The method can not safely destroy various initiating explosive in batches (not only NHN, but also most of the initiating explosive can not be destroyed by directly soaking in diesel oil and can be realized only after treatment, because the method is adopted to directly pour dry NHN into the diesel oil for soaking, firstly, certain risk exists, and because the initiating explosive powder state has high mechanical sensitivity, the risk of accidental explosion of soaking operation exists (when the initiating explosive is pressed into a detonator, the initiating explosive is in a block shape, the mechanical sensitivity is reduced, and the risk of the detonator diesel oil soaking operation is controllable), secondly, when the initiating explosive is soaked in oil production diesel oil for burning, the initiating explosive needs to be spread, and when the initiating explosive is directly soaked in the NHN initiating explosive (non-aqueous) state, the phenomenon of burning and explosion easily occurs in the burning process under the condition of certain thickness, the unexpected loss is caused, and the safety risk is increased.
Disclosure of Invention
One of the objectives of the present invention is to provide a safe method for selling NHN initiating explosive to solve the above problems.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a safety pin blasting method of NHN initiating explosive comprises a pretreatment step and an incineration step, wherein the pretreatment step comprises the following steps: soaking NHN initiating explosive in water, dewatering, controlling the water content of NHN initiating explosive at 7-10 wt%, and soaking the dewatered initiating explosive in inflammable liquid B with flash point lower than 45 deg.c at 28 deg.c, such as diesel oil, kerosene, etc.
Firstly, the purpose of the soaking of this application is to passivate the NHN, reduce the sensitivity, facilitate subsequent destruction work. The larger the moisture content is, the more insensitive the medicament is, the higher the operation safety is, however, if the moisture content is too high, the phenomenon of incomplete combustion can occur in the subsequent combustion destruction treatment process, and the subsequent treatment risk is destroyed, so the purpose of adopting alcohol dehydration is to control the NHN to be about 7-10%, and the control in the range not only can ensure the safety of the destruction operation, but also can ensure the complete destruction;
the purpose of the immersion is to reduce the sensitivity of the NHN primer. Because NHN is after soaking, water is fully filled between the medicament granule, keeps apart it, has reduced the friction between the medicament and has taken place the explosion probability on the one hand, and on the other hand, water also can in time derive the heat that the medicament produced and volatilize as the medium, makes it be difficult for taking place the explosion when external energy arouses. Meanwhile, when the water content is excessive, the operation safety is higher, but the more the water content is, the more incomplete the combustion and destruction is, the residual medicament after combustion basically becomes dry medicament, the sensitivity is higher, and the potential safety hazard is buried for subsequent collection and treatment. Therefore, it is necessary to control the water content within a certain range and to perform incineration treatment. The purpose of alcohol dehydration is to control the alcohol dehydration within a proper range, and the operation is simple and practical and is convenient to control.
The test shows that: if the moisture content of the NHN is too large, the NHN is burnt after soaking the diesel oil, incomplete burning can occur, and the NHN remains. Therefore, the method controls the NHN within a certain water content range, and ensures stable combustion and no explosion when the NHN is destroyed by soaking combustion.
Further, NHN, DDNP and lead nitride are all initiating explosives, but their properties are different. Firstly, the mechanical sensitivity of the lead nitride is sensitive, the lead nitride still has high sensitivity even if the lead nitride is soaked in water, meanwhile, the detonation of the initiating explosive is extremely fast to increase, the initiating explosive is easy to explode when being burnt and destroyed, and the initiating explosive cannot be destroyed by burning. Although the sensitivity of DDNP can be reduced after soaking in water, the detonation growth of DDNP is also relatively large, and the DDNP is still relatively easy to explode when destroyed by combustion. In addition, after the DDNP is soaked, the water body is dyed yellow, and the washing water of the DDNP still needs to be treated. The detonation of the NHN initiating explosive grows relatively slowly, so that the NHN initiating explosive has certain precondition by adopting a combustion destruction method, and the combustion state is controlled by the moisture content, so that the NHN initiating explosive is safely and stably combusted, and the phenomenon of converting detonation into detonation does not occur. That is, the method of the present invention can be used only for NHN and not for DDNP or other initiating explosive such as lead azide.

The burning device can be replaced by a common metal plate without a special burning device, and the ignition device can be replaced by a firing cable so as to improve the convenience of destroying the NHN medicament.
As a preferred technical scheme: soaking for 30 min; the suction filtration time is 5 min; the soaking time in diesel oil is 30 min.
As a preferred technical scheme: a small amount of combustible substances such as paper scraps and the like can be added into the pretreated and passivated medicament, so that the subsequent spreading operation of the medicament is facilitated, and the destruction time of the medicament is shortened.
