Abstract
The utility model discloses a regenerative roaster gas leakage emergency treatment device which comprises an emergency fan (2), a gas alarm apparatus (3) and a PLC. The gas alarm apparatus (3) is arranged at a position which is prone to leakage on a roaster (1). The emergency fan (2) is arranged at the upper part of the roaster (1). The gas alarm apparatus (3) and the emergency fan (2) are respectively electrically connected with the PLC, and are electrically and dynamically connected through the PLC. According to the utility model, the gas alarm apparatus matches the emergency fan, thus alarm, emergency treatment and other follow-up works can be carried out after gas leakage; safety accidents are avoided; the risk of gas poisoning is reduced; and the regenerative roaster gas leakage emergency treatment device has the advantages of simple structure, low cost, reliable work and convenient installation.
Description
Technical field
The utility model belongs to smelting iron and steel technical field, further belongs to safe emergence technology field, be specifically related to a kind of simple in structure, cheap, reliable operation, heat-storage ladle roaster gas leak emergency treatment device easy for installation.
Background technology
Heat accumulating type baking of tundish device is a kind of device for toasting ladle, general steel ladle after new block and splendid attire molten steel all need to toast as last, so ladle baking facility plays vital effect.What heat accumulating type baking of tundish device adopted is a kind of gas waste heat recovery regenerative combustion technology, replaces switch operating carry out the waste heat in recovered flue gas in heat absorption and release state by paired heat storage.Heat accumulating type baking of tundish device has been obtained good power savings advantages and cured effect in continuous casting is produced, and meanwhile, has also played positive role to reducing environmental pollution.In heat accumulating type, wrap in its heat energy medium of line apparatus for baking and be generally coal gas of converter, carbon monoxide CO content is high compared with coke-oven gas, and colorless and odorless, under prior art condition of work, there will be the dangerous situations such as gas leak.Particularly in the winter time, temperature is low, and the coal gas of leakage is difficult for distributing, and very easily causes personnel's gas poisoning.Conventionally the technical measures of taking are: in the time there is gas leak, alarm starts to report to the police, and the operating personnel of the production top class in a kindergarten are wearing after correlative protection articles for use, and the emergency ventilator that turns on the gas-fire dispels coal gas, process, this is large and process the situations such as hysteresis with regard to dangerous degree again.For this reason, research and development one can detect gas leak state automatically, and the heat-storage ladle roaster gas leak emergency treatment device of OnNow emergency ventilator, is with a wide range of applications.
Utility model content
It is a kind of simple in structure, easy for installation that the purpose of this utility model is to provide, and can automatically detect gas leak state, and the heat-storage ladle roaster gas leak emergency treatment device of OnNow emergency ventilator.
The purpose of this utility model is to realize like this, described emergency ventilator, gas alarm instrument and the PLC of comprising, described gas alarm instrument is arranged at roaster the position of leaking easily occurs, described emergency ventilator is arranged at roaster top, and described gas alarm instrument is connected control with PLC with emergency ventilator.
The structure that the utility model adopts emergency ventilator and gas alarm instrument to coordinate, the interlock control of gas alarm instrument and emergency ventilator and PLC, realized the follow-up work such as warning and emergency processing after gas leak, the generation of stopping security incident, has reduced the risk of gas poisoning.The utility model is simple in structure, cheap, and reliable operation is easy for installation.
Brief description of the drawings
Fig. 1 is that the utility model duty master looks schematic diagram;
In figure: 1-roaster, 11-bracing frame, 12-pipeline valve, 13-gas pipe, 14-ladle baking facility, 15-pedestal, 2-emergency ventilator, 3-gas alarm instrument.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion or the improvement done based on the utility model training centre, all fall into protection domain of the present utility model.
As shown in Figure 1, the utility model comprises emergency ventilator 2, gas alarm instrument 3 and PLC, described gas alarm instrument 3 is arranged at roaster 1 position of leaking easily occurs, described emergency ventilator 2 is arranged at roaster 1 top, described gas alarm instrument 3 and emergency ventilator 2 are electrically connected with PLC respectively, and electrically dynamically connect by PLC.
Described gas alarm instrument 3 arranges near gas pipe 13 and pipeline valve 12 junctions, and is positioned at roaster 1 outer edge.
Described gas alarm instrument 3 adopts high temperature resistant type gas alarm instrument.
The coal gas detection sensitivity of described gas alarm instrument 3 is less than 50ppm.
Described emergency ventilator 2 is arranged on pedestal 15, both affixed cooperations.
On gaspipe line before described emergency ventilator 2, pipeline valve 12 is set.
The outer protective cover that arranges of described emergency ventilator 2.
The response time of described emergency ventilator 2 should be less than 2 seconds.
principle of work of the present utility model and the course of work:
The structure that the utility model adopts emergency ventilator and gas alarm instrument to coordinate, the interlock control of gas alarm instrument and emergency ventilator and PLC.
When use, in the time that gas alarm instrument detects gas concentration higher than 50ppm, gas alarm instrument is reported to the police, and emergency ventilator starts simultaneously, dispels the coal gas of leakage.
