Technical Field

The utility model belongs to equipment for the environmental protection trade, in particular to dangerous waste storage warehouse steam extinguishing device.

Background

At present, in the hazardous waste storage warehouse, the majority is chemical industry class pollution waste, the overwhelming majority has characteristics such as inflammable, explosive, and it is all great to deposit the quantity, current extinguishing device is fire extinguisher and portable dry powder fire extinguisher, the dry powder fire extinguisher is difficult to control the condition of a fire when taking place the condition of a fire, the fire department also is difficult to arrive the scene very first time, the condition of a fire continues to stretch and is difficult to control, and can cause secondary pollution in the water extinguishing process to the hazardous waste who burns, a large amount of water can take hazardous waste to flow into domestic sewage collecting pit together, the polluted environment. In the hazardous waste disposal industry, almost no waste heat recovery device is provided, and the surplus steam capacity cannot be reasonably utilized.

Disclosure of Invention

The utility model aims to overcome the technical defects, and provides a steam fire extinguishing device for a hazardous waste storage warehouse, which has simple structure, convenient installation and flexible and reliable use.

The utility model provides a technical scheme that technical problem adopted is: the hazardous waste storage warehouse steam fire extinguishing device comprises a hazardous waste warehouse, a control circuit and a steam pipeline, and is characterized in that the device is also provided with a pressure reducing valve, a remote steam main valve, a drain valve, a steam nozzle, a smoke-sensitive and temperature-sensitive detector, a warehouse partition valve and a central control module; the connection relationship is as follows: the control system comprises a central control module U, a plurality of warehouse subarea valves on one side of the central control module U, a pressure reducing valve and a remote steam master valve, wherein 4 feet of the central control module U are connected with a plurality of warehouse subarea valves on the other side of the central control module U through a control line, 2 and 3 feet of the central control module U are respectively connected with smoke-sensitive and temperature-sensitive detectors in a plurality of warehouse subareas on two sides through control lines, a steam pipeline is paved on the upper portion of the periphery of each warehouse subarea, the steam pipeline is connected with a main steam pipeline through the warehouse subarea valves outside each warehouse subarea, a plurality of steam nozzles facing downwards are arranged on the steam pipeline in each warehouse subarea, and a plurality of drain valves are connected on one side where.

The utility model has the advantages that: the fire source can be put out at the first time after the steam fire extinguisher is used; the fire extinguisher can effectively prevent people from approaching the storage warehouse to extinguish fire, and plays a safety role; a large amount of water is not used for extinguishing fire, secondary pollution caused by the environment is not influenced, and the danger of fire and explosion caused again can be reduced by using steam for extinguishing the fire; the fire-extinguishing agent avoids the rapid reaction of a large amount of water after fire extinguishment, and causes danger to personnel due to secondary combustion; the steam fire extinguishing device is simple, convenient to install, flexible to use and easy to maintain. No residue is left after fire extinguishing, and no pollution is caused to protected equipment, substances and the like.

The following description is made in detail by way of example with reference to the accompanying drawings.

Fig. 1 is a structural plan layout view of a steam fire extinguishing apparatus of a hazardous waste storage warehouse.

Fig. 2 is an enlarged view of a partial unit structure in fig. 1.

In the figure, 1-pressure relief valve; 2-a main remote steam valve; 3-a steam line; 4-a drain valve; 5-smoke and temperature sensing detector; 6-steam spray head; 7-warehouse section valves; 8-a control line; 9-a hazardous waste warehouse; and U-central control module.

Detailed Description

In the embodiment, referring to the attached figures 1 and 2, the hazardous waste storage warehouse steam fire extinguishing device is characterized in that a hazardous waste warehouse 9 is arranged into two sides, five warehouse partitions 9-1 are arranged on each side, the opposite positions of the warehouse partitions 9-1 on the two sides are respectively connected with a smoke temperature-sensing detector 5 in each warehouse partition 9-1 through control lines 8, and two smoke temperature-sensing detectors 5 are arranged in each warehouse partition 9-1. The smoke-sensitive and temperature-sensitive detector 5 is connected with the pins 2 and 3 of the central control module U through a control circuit 8. And a pin 1 of the central control module U is connected with 5 warehouse partition valves 7, a pressure reducing valve 1 and a remote transmission steam main valve 2 on one side through a control line 8, and a pin 4 of the central control module U is connected with 5 warehouse partition valves 7 on the other side through a control line 8. The upper part of the periphery in each warehouse partition 9-1 is paved with a steam pipeline 3, the steam pipeline 3 is connected with a main steam pipeline 3 through a warehouse partition valve 7 outside each warehouse partition 9-1, six steam nozzles 6 in the downward direction are arranged on the steam pipeline 3 in each warehouse partition 9-1, and four steam traps 4 are connected with one side where the total steam pipeline 3 is connected with the steam distributing pipeline 3.

The utility model discloses a theory of operation is: the steam fire extinguishing device of the hazardous waste storage warehouse takes a steam boiler for production or living as a steam source, and is controlled by a central control module U through arranging pipelines in each partition of the warehouse. The water vapor is inert gas with high heat content, the concentration of the combustible gas is lower than the lower combustion limit or the concentration of oxygen in the air is reduced by diluting or replacing the combustible gas and the combustion-supporting gas oxygen in the combustion area, the combustible gas is not enough to be combusted, and the low-pressure steam is attached to the surface of the hazardous waste to block the hazardous waste from contacting with the oxygen to extinguish the fire; the oxygen in the dangerous material storage warehouse is replaced by the steam, and the continuous combustion of the dangerous waste is avoided.
