Abstract
The utility model belonging to a safety device mainly relates to a safety protection device for the roots blower in the flow of the desulfurization and includes an inlet oil pressure seat plate valve, a system cutoff oil pressure seat plate valve and an oil circuit system which controls the two valves. The utility model is provided with a manual reversing valve station for the two valves and an accumulator on the pipeline of that the gas production high-pressure oil pump produces the hydraulic oil. The utility model solves the problems of that the blower is reversely rotated and is broken when the sudden events such as the electric shaking, parking or power failure and so on.
Description
Technical field:
The utility model belongs to the blower fan safety protection device, is chiefly directed in the desulfurization flow process protection device to roots blower.
Background technique:
In the coal gas desulfurization flow process; semi-water gas enters roots blower through inlet oil pressure base-plate valve;,, when regulating tolerance, regulate (being the aperture of regulating system shortcut oil pressure base-plate valve) by system's shortcut and meet accident to cooling tower through system's shortcut oil pressure base-plate valve; generally be to utilize system's water seal release; prevent the roots blower reversing, in case smash blower fan, but this device can not guarantee blower fan safety reliably; when closing blower fan gateway valve, cause the blower fan reversing through regular meeting, smash blower fan.
Summary of the invention:
The purpose of this utility model is in order to solve the above problems, and provides a kind of when running into accident such as rolling electricity, parking or power failure, prevents from the blower fan reversing to be used for guaranteeing safe roots blower Safeguard.
The utility model adopts following solution: a kind of Safeguard of roots blower, comprise inlet oil pressure base-plate valve, system's shortcut oil pressure base-plate valve and control the oil-way system of two valves, the oil pressure base-plate valve that it is characterized in that entering the mouth is connected with the hand-operated direction valve station by oil-way system with system shortcut oil pressure base-plate valve, and accumulator is connected to the hand-operated direction valve station and provides on the pipeline of hydraulic oil.
Roots blower Safeguard of the present utility model, the accumulator of setting can be for one or more.The fan trouble warning device is set in the hand-operated direction valve station, and warning device comprises electric bell, warning light and ammeter.
Of the present utility modelly come hydraulic oil at first through the accumulator pressure accumulation from gas making, again through hand-operated direction valve, link to each other with system shortcut oil pressure base-plate valve by oil circuit and inlet oil pressure base-plate valve, meet urgency, hand-operated direction valve is got to the position of opening, and hydraulic oil enters inlet oil pressure base-plate valve oil cylinder through oil circuit, and inlet oil pressure base-plate valve is closed, semi-water gas can not be flow backwards, and (add and how to open system's shortcut oil pressure base-plate valve) is to reach the protection purpose.Inlet oil pressure base-plate valve and system's shortcut oil pressure base-plate valve all are pressure-actuated by hydraulic oil, so even this protective gear that has a power failure still can normally move.
Description of drawings:
Fig. 1 is a schematic representation of the present utility model.
Embodiment:
As shown in Figure 1, roots blower 5 ingress joint access oil pressure base-plate valves 4., 6, two base-plate valves of outlet port connected system shortcut oil pressure base-plate valve 4,6 are oil pressure actuated.For roots blower 5 is provided with warning device, warning device is arranged on the hand-operated direction valve station, and warning device comprises ammeter 7, electric bell 8 and warning light 9, and whether ammeter 7 is used to refer to blower fan 5 and cuts off the power supply, and the effect of electric bell 8 and warning light 9 is fault alarms.For system is provided with hand-operated direction valve station 3, the hand-operated direction valve station is provided with hand-operated direction valve for 3 li, and the hydraulic oil at hand-operated direction valve station 3 is taken from gas making high pressure oil pump 2, two accumulators 1 is set on this pipeline is used to store pressure.When rolling electricity, certain typhoon machine tripping operation or parking; ammeter 7 does not have indication; electric bell 8 and warning red light 9 power alarm; the operator can close the inlet oil pressure base-plate valve 4 of blower fan 5 rapidly; open system's shortcut oil pressure base-plate valve 6 simultaneously; make its pressure directly import the fans entrance house steward, prevent that the gas refluence from driving blower fan 5 reversings, plays a protective role.
Claims (3)
1, a kind of roots blower Safeguard, comprise inlet oil pressure base-plate valve, system's shortcut oil pressure base-plate valve and control the oil-way system of two valves, the oil pressure base-plate valve that it is characterized in that entering the mouth is connected with the hand-operated direction valve station by oil-way system with system shortcut oil pressure base-plate valve, and accumulator is connected to the hand-operated direction valve station and provides on the pipeline of hydraulic oil.
2, roots blower Safeguard according to claim 1 is characterized in that the accumulator that is provided with can be for one or more.
3, roots blower Safeguard according to claim 1 is characterized in that the fan trouble warning device is set in the hand-operated direction valve station, and warning device comprises electric bell, warning light and ammeter.
