A kind of limited confined space toxic gas automatically removes system, belongs to technical field of sewage.The system includes toxic gas detection probe, alarm, controller, ventilation fan, dosing pump and medicine insufflation showerhead.Controller is not only electrically connected with the toxic gas detection probe and alarm being arranged in limited confined space, but also is electrically connected with ventilation fan and dosing pump.For controller when detecting that toxic gas is exceeded by toxic gas detection probe, alarm sends sound-light alarm, after notifying personnel to withdraw, controls dosing pump sprinkling medicine first, then control ventilation fan to take a breath.The system can detect the content of the toxic gas in limited confined space, and energy and alarm, spray and ventilation in time, ensure the safety and health of operating personnel.
Description
Technical field
It the utility model is related to a kind of limited confined space toxic gas and automatically remove system, belong to sewage disposal technology neck
Domain.
Background technology
In sewage disposal system, there are structures such as piping lane, closed cistern, closed storage basins, belong to limited
Confined space, since sewage, sludge stop in above structures, fermenting produces a large amount of toxic and harmful gas, due to being limited
Confined space, it is difficult to distribute naturally.It is for limited Working in confined space normal step：Toxic gas is detected before operation to contain
Amount, if exceeded need first live ventilation, then qualified operation again on inspection, but for being frequently necessary to walkaround inspection
Limited confined space, if all repeated the above steps before entering every time, loses time, influences work efficiency；It is in an emergency,
Can not timely processing, influence to produce；Toxic gas is still easily regenerated during operation, operating personnel is difficult to find in time, such as
Fruit is discharged not in time and continuing operation can be in peril of one's life.
The content of the invention
In order to overcome problems of the prior art, the utility model provides a kind of limited confined space toxic gas certainly
Dynamic removal system, the system should be able to detect the content of the toxic gas in limited confined space, and energy and alarm, spray in time
And ventilation, ensure the safety of operating personnel and health.
The technical solution of the utility model is：A kind of limited confined space toxic gas automatically removes system, it includes
Confined space, toxic gas detection probe, alarm and controller are limited, ventilation fan is equipped with the closed wall of limited confined space
With ventilation filter, it further includes dosing pump, medicine insufflation showerhead and filter；The dosing pump is arranged on limited confined space
Outside, pass through medicine insufflation showerhead and filter of the pipeline connection in the limited confined space；The controller not only with
Be arranged in limited confined space toxic gas detection probe and alarm be electrically connected, but also with ventilation fan and dosing
Pump is electrically connected；When detecting that toxic gas is exceeded by toxic gas detection probe, alarm can be sent out the controller
Go out sound-light alarm, after notifying personnel's emergency escape, control dosing pump to be sprayed into limited confined space first and neutralize toxic gas
Medicine, then control ventilation fan to take a breath limited confined space.
Dirt discharge canal is equipped with the limited confined space.
The beneficial effects of the utility model are：This limited confined space toxic gas automatically removes system and includes poison gas
Body detection probe, alarm, controller, ventilation fan, dosing pump and medicine insufflation showerhead.Controller not only be arranged on it is limited close
The toxic gas detection probe and alarm closed in space is electrically connected, but also is electrically connected with ventilation fan and dosing pump
Connect.For controller when detecting that toxic gas is exceeded by toxic gas detection probe, alarm sends sound-light alarm, notifier
After member withdraws, dosing pump sprinkling medicine is controlled first, then control ventilation fan to take a breath.The system can detect limited confined space in time
The content of interior toxic gas, and energy and alarm, spray and ventilation, ensure the safety and health of operating personnel.
Brief description of the drawings
Fig. 1 is the schematic diagram that a kind of limited confined space toxic gas automatically removes system.
In figure：1st, limited confined space, 2, dosing pump, 3, toxic gas detection probe, 4, medicine insufflation showerhead, 4a, mistake
Filter, 5, ventilation fan, 5a, ventilation filter, 6, alarm, 7, dirt discharge canal.
Embodiment
The utility model is illustrated below in conjunction with the drawings and the specific embodiments：
Fig. 1 shows that a kind of limited confined space toxic gas automatically removes the schematic diagram of system.This limited confined air
Between toxic gas automatically remove system include limited confined space 1, toxic gas detection probe 3, alarm 6, controller, dosing
Pump 2, medicine insufflation showerhead 4 and filter 4a.Ventilation fan 5 and ventilation filter are equipped with the closed wall of limited confined space 1
5a, dosing pump 2 are arranged on the outside of limited confined space 1, are sprayed by medicine of the pipeline connection in limited confined space 1
Nozzle 4 and filter 4a.The controller not only toxic gas detection probe 3 and alarm 6 with being arranged in limited confined space 1
It is electrically connected, but also is electrically connected with ventilation fan 5 and dosing pump 2.Controller is passing through 3 inspection of toxic gas detection probe
Measure toxic gas it is exceeded when, alarm 6 can send sound-light alarm, after notifying personnel's emergency escape, first control dosing pump 2 to
Sprinkling neutralizes the medicine of toxic gas in limited confined space 1, then controls ventilation fan 5 to take a breath limited confined space 1.Have
Limit and dirt discharge canal 7 is equipped with confined space 1.
In sewage disposal system exemplified by it common are poisonous gas hydrogen sulfide：When toxic gas detection probe 3 receives
When concentration of hydrogen sulfide reaches 2mg/l, 6 one sections of switching signal alarms of alarm, the ventilating fan 5 installed in limited confined space 1 is opened
Open, outwards exhaust, when toxic gas detection probe 3, which receives concentration of hydrogen sulfide, reaches 9mg/l, 6 two sections of switch letters of alarm
Number alarm, dosing pump 2 opens, and calcium hydroxide solution is by the spray of medicine insufflation showerhead 4 to limited confined space 1, with vulcanization
Hydrogen neutralizes, and reaches neutralization of acid with base.
