Description
Technical field
The invention belongs to chemical enterprise accident waste water collection technique field, the collection storage method of especially a kind of chemical workshop fire failure waste water.
Background technology
The early stage each chemical workshop being constructed and put into operation such as Xiamen at south China, because the present situations such as limited space, plant area is shaping, underground pipe network is complicated, the environmental pollution event caused by fire failure takes place frequently, therefore outside preventing fire failure waste water, row causes this area's environmental pollution to become an important process of accident emergency rescue, and perfect fire failure waste water collection Response project also more and more draws attention.
The floor space of usual chemical workshop and the gross weight of transfer every day chemical are given; the tank car storing transfer chemical it is configured with in chemical workshop; several indoor fire-fighting hydraulic giants it are configured with in chemical workshop; several outdoor fire fighting hydraulic giants it are configured with outside chemical workshop; described indoor fire-fighting hydraulic giant and described outdoor fire fighting hydraulic giant go out, in 3.0 hours, the regulation that water inventory meets GB50016-2006 at fire failure Fire Fighting Time, and chemical workshop residingly is estimated as Tmm at the maximum average rainfall of fire failure Fire Fighting Time in 3.0 hours.
Does is problem: how existence conditions according to chemical workshop processes the environmental pollution caused due to fire failure? take which type of collection storing mode comparatively reasonable the fire failure waste water of chemical workshop? collection storage method about this respect yet there are no relevant report.
Summary of the invention
For solving the problem; the present invention provides the collection storage method of a kind of chemical workshop fire failure waste water; this collection storage method is by the maximum of calculating accident waste water; by building cofferdam, chemical workshop gate and build liquid collecting hole; both the collection requirement of fire failure waste water had been met; also for the final discharge of fire failure waste water lays the foundation, reach the production environment of protection chemical workshop preferably, prevent the object causing secondary environment contaminated because fire failure waste water expands.
For achieving the above object, the present invention adopts following technical scheme:
A collection storage method for chemical workshop fire failure waste water, relates to the floor space Sm of given chemical workshop in this collection method of disposal2, given transfer every day chemical gross weight be W ton, several indoor fire-fighting hydraulic giants it are configured with in chemical workshop, being configured with several outdoor fire fighting hydraulic giants outside chemical workshop, described indoor fire-fighting hydraulic giant and described outdoor fire fighting hydraulic giant are Lm at the water inventory that goes out of fire failure Fire Fighting Time in 3.0 hours3, Lm3Meeting the regulation of GB50016-2006, chemical workshop residingly is estimated as Tmm at the maximum average rainfall of fire failure Fire Fighting Time in 3.0 hours; This collection method of disposal also uses waste collection pipeline, control valve, liquid collecting hole, float(ing)valve, anti-explosion submersible pump, housing, flexible pipe, liquidometer, discharge opeing mouth, fire failure waste water comprise described transfer chemical, described in go out water inventory L and described rainfall amount, the feature of the present invention is as follows:
The storage tank that can store the heavy transfer chemical of W ton is located on the horizontal base at the outer arbitrary place of chemical workshop, liquid collecting hole is set between storage tank and chemical workshop, storage tank either side end configures liquidometer and configuration level discharge opeing mouth bottom it, anti-explosion submersible pump is arranged on bottom, liquid collecting hole, the flexible pipe drawn from storage tank upper end connects with anti-explosion submersible pump, anti-explosion submersible pump realizes opening or closing down by housing, float(ing)valve is set in liquid collecting is cheated and cheats upper end in liquid collecting and hole lid is set, waste collection pipeline is configured in chemical workshop, waste collection pipeline is extended in liquid collecting hole, the waste collection pipeline extended arranges control valve, chemical workshop gate place is provided with the cofferdam of H height, the cofferdam of H height makes the concentrated reservoir forming fire failure waste water in chemical workshop, fire failure waste water just can be implemented effectively to collect and store by the summation volume adding liquid collecting hole and storage tank, direct pump can also be cheated by liquid collecting while described concentrated reservoir carries out collecting storage to enter tank car and transfer to the unit of qualification to carry out harmless treatment, finally reach and prevent the not outer row of fire failure waste water, object free from environmental pollution,
Above-mentioned H to be drawn according to the maximum estimation amount M of fire failure waste water, the maximum estimation amount M=N+L+E of fire failure waste water, in this formula:
N is the estimation volume amounting to rear transfer chemical, if W is ton weight, then and W �� Nm3;
E is the estimation volume m of rainwater3If estimating as T=40mm at the maximum average rainfall of fire failure Fire Fighting Time in 3.0 hours, then E=S �� T, it is noted that the unit of T to be converted to m from mm;
Then H=M/S.
Volume >=the 2m in above-mentioned liquid collecting hole3, liquid collecting hole exceeds terrace benchmark and adopts concrete structure, and the inwall in liquid collecting hole is through Anti-seeping technology.
Waste collection pipeline adopt stainless-steel pipe, the outer wall at described stainless-steel pipe whitewashes protective system, re-use brick, concrete build groove and described stainless-steel pipe is wrapped up.
Storage tank adopts PE material to be made, in case a large amount of heats of release cause storage tank impaired during fire, storage tank can make fire failure waste water be convenient to layering and process in storage process.
Owing to adopting technical scheme described above, the present invention produces following positively effect:
1, the environmental requirement that the waste water that the cofferdam that the present invention is provided with H height solves on the one hand under fire failure is collected storage problem and met outside chemical workshop, solve the emergent facility of early stage chemical workshop on the other hand and do not match perfect problem, greatly saved and built up this again.
2, the present invention can effectively solve the waste water under fire failure state and collect storage problem, thus effluent stream does not rush down under enclosed environment, and operating process is simple and easy and practical, thus reaches the object of protection of the environment.
3, the cofferdam being provided with H height serves Sources controlling effect in fire failure waste water collection storage process, and construction cost of the present invention is low, and to construction, relatively morning, the incomplete chemical workshop of environmental emergency Facilities serialized have reference value.
4, liquid collecting hole, storage tank have certain volume, and the fire failure waste water that a small amount of leakage material or little fire bring is played storage effect, can play delamination in the process that fire failure waste water leaves standstill in storage tank simultaneously, process of being more convenient for.
5, a large amount of waste water that fire failure produces are cheated direct pump through liquid collecting and are entered tank car, transfer to the unit of qualification to carry out harmlessness disposing, store and outward transport process formative dynamics balance in collection, finally reach the not outer row of Accident prevention waste water, object free from environmental pollution.
