Description
Technical field
The utility model relates to a kind of pharmaceutical factory clean area equipment with the anti-down fill system of draining, is applicable to pharmaceutical factory clean area installed device draining.
Background technology
Factory building inside, pharmaceutical factory, especially biological pharmaceutical factory factory building cleanliness factor requires very high, clean area has the drainage pipe of drainage requirement equipment and being connected of factory building gutter need accomplish effective partition, prevent that the pressure that occurs in the gutter from recharging in clean area environment or the equipment, pollute clean area environment or equipment pipe, thus the cross pollution that produces.And the gutter of clean room is connected with a plurality of equipment, for the high temperature water that the prevents equipment exhausting equipment to other exerts an influence, the high temperature discharge of equipment is had the requirement of cooling.
The utility model content
According to above requirement, what the utility model need solve is: clean area equipment anti-down fill system of draining in a kind of pharmaceutical factory is provided, at first be to guarantee that equipment normally discharges, have the cooling function, and can prevent effectively that the pressure in the drainage pipe from recharging in equipment or the factory building clean area.
The pharmaceutical factory provided by the utility model clean area equipment anti-down fill system of draining, comprise the pharmaceutical factory factory building, also comprise discharge casing, the equipment drainage pipe of pharmaceutical factory factory building connects discharge casing by draining valve, the terminal factory building drainage pipe that connects of discharge casing, and discharge casing also connects cooling water pipeline by cooling water valve, relief valve is installed on the discharge casing, the inner installation data harvester of discharge casing, data acquisition unit connection control system, control system are controlled draining valve, cooling water valve and relief valve respectively.
Deflection plate and following deflection plate are installed in the described discharge casing, and the upper end of last deflection plate is fixed on the discharge casing top, and the lower end of last deflection plate and the bottom of discharge casing are gapped; Following deflection plate is arranged on deflection plate one side, and its lower end is fixed on the bottom of discharge casing, and its upper end is gapped with the discharge casing top.
Data acquisition unit comprises temperature pick up, pressure sensor and liquid level sensor, and data acquisition unit all is connected with control system.Control system comprises treating apparatus and accessory circuit thereof, be used for collecting temperature sensor, pressure sensor and the detected signal of liquid level sensor, and according to presetting to control cut-offfing of draining valve, cooling water valve and relief valve, realize discharging cooling, the anti-function of recharging automatically.
The outlet conduit of discharge casing connects the factory building drainage pipe by the pipeline tie point.By connection and the maintenance that the pipeline tie point makes things convenient for pipeline is set.
Draining valve is installed on the drainage pipe of equipment, and cooling water valve is connected with cooling water pipeline, and relief valve leads directly to atmosphere.Last deflection plate in the discharge casing and following deflection plate are used for mixing high temperature discharge water and cooling water.And following deflection plate root has slow round, guarantees that discharge casing can thoroughly discharge.
Operating principle:
The drainage pipe of discharge casing is connected with the factory building gutter is airtight, guarantees can not exert an influence to installation environment.
Discharge casing relief valve pipeline leads directly to atmosphere, guarantees can not exert an influence to installation environment.
During the equipment draining, temperature pick up detects temperature at discharging condensate at the drainage pipe place, if surpass the exhaust temperature limit value, control system is then opened cooling water valve, is used for the cooling down high-temperature discharge water.
In the equipment drainage procedure, liquid level sensor and pressure sensor detect when the interior liquid level of discharge casing exceeds standard or pressure exceeds standard, control system is then closed draining valve earlier, prevent from flowing backwards and recharge, the equipment draining stops, simultaneously, open relief valve, discharge manifold pressure, guarantee that pipeline tie point place can be owing to manifold pressure produce leakage greatly, thereby to the environment generation pollution of clean area.After waiting for that factory building drainage pipe internal pressure is normal, equipment restarts draining.
The beneficial effect that the utility model has is:
The native system structure is perfect, and the various risks that occur are had corresponding detection mode and processing mode, greatly reduces the risk of recharging the cross pollution that causes in the drainage procedure.Whole system can be controlled automatically, and the real estate management for the treatment of plant road pressure increases the influence to equipment draining and the generation of clean area environment timely and effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model:
Among the figure: 1, draining valve; 2, discharge casing; 3, temperature pick up; 4, pressure sensor; 5, liquid level sensor; 6, relief valve; 7, cooling water valve; 8, go up deflection plate; 9, following deflection plate; 10, pipeline tie point.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
The pharmaceutical factory clean area equipment anti-down fill system of draining as shown in Figure 1, comprise the pharmaceutical factory factory building, also comprise discharge casing 2, the equipment drainage pipe of pharmaceutical factory factory building connects discharge casing 2 by draining valve 1, the discharge casing 2 terminal factory building drainage pipes that connect, and discharge casing 2 also connects cooling water pipeline by cooling water valve 7, relief valve is installed on the discharge casing, the inner installation data harvester of discharge casing, data acquisition unit connection control system, control system are controlled draining valve 1, cooling water valve 7 and relief valve 6 respectively.
