Abstract
The utility model relates to a blow-down device of a compressor at negative pressure, atmospheric pressure and micropositive pressure. The blow-down device comprises a blow-down tank (7) and a blow-down opening, wherein the blow-down tank (7) is communicated with a front liquid separator by a pipeline I (2) which is provided with a control valve I (5); and the blow-down tank (7) is communicated with a first-stage cylinder seat (4) by a pipeline II (3) which is provided with a control valve II (6). The blow-down device is characterized in that the blow-down tank (7) is communicated with a second-stage air inlet pipe (11) by a pipeline III (10) which is provided with a control valve III (9); and the blow-down opening is provided with a control valve IV (8). The blow-down device has the beneficial effects that the pressure of gas compressed by the compressor is utilized as blow-down power of blow-down points under the state of the negative pressure, the atmospheric pressure and the micropositive pressure, and the blow-down purpose is achieved, so that the blow down of the compressor under the states is solved. The blow-down device has the advantages that the structure is simple, the reliability is high, the safe and practical effects are achieved and the total economy is greatly increased.
Description
Technical field
The utility model relates to a kind of compressor, the compressor drainage device at especially a kind of negative pressure, barometric pressure, micro positive pressure place.
Background technique
Get into the preceding gas of compressor one-level cylinder and often contain liquid water; In order not make liquid water get into cylinder; Cause liquid hammer to damage compressor, in the air inlet pipeline system, be provided with preceding liquid/gas separator usually, come out liquid water contained in the gas through separator separates; Emit the safety during with the assurance compressor operating then through blowdown valve.But under often many situation; The one-level suction pressure of compressor is to be lower than atmospheric pressure or to equal atmospheric pressure and at slight positive pressure state; Compressor operating is when cylinder is air-breathing; Often inhale the gas pressure of (before containing liquid/gas separator with the first-stage cylinder seat air inlet be sidelong dirty jointing) in the one-level air inlet pipeline system and become to be lower than atmospheric pressure, during compressor operating.When liquid/gas separator and first-stage cylinder seat blowdown place blowdown valve are put dirt before opening; Because blow down tank gas inside pressure is lower than barometric pressure; Thereby the water row who makes water that separator separates comes out and the air inlet of first-stage cylinder seat be sidelong dirty jointing does not go out, and brings hidden danger for the operation of compressor.
The model utility content
The purpose of the utility model is exactly to be lower than barometric pressure in order to overcome existing blow down tank gas inside pressure; Thereby the defective that the water row who makes water that separator separates comes out and the air inlet of first-stage cylinder seat be sidelong dirty jointing does not go out, and the compressor drainage device at a kind of negative pressure that provides, barometric pressure, micro positive pressure place.
The utility model solves the technological scheme that its technical problem adopted:
The compressor drainage device at negative pressure, barometric pressure, micro positive pressure place comprises blow down tank and sewage draining exit, and blow down tank is communicated with preceding liquid/gas separator through pipeline one; Pipeline one is provided with control valve one; Blow down tank is communicated with the one-level cylinder block through pipeline two, and pipeline two is provided with control valve two, it is characterized in that: blow down tank is communicated with the secondary suction tude through pipeline three; Pipeline three is provided with control valve three, on sewage draining exit, is provided with control valve four.
External sewage draining exit at blow down tank has increased control valve four; When its objective is compressor operating; This valve will be in closed condition; In case preceding liquid/gas separator, first-stage cylinder seat are in the water of negative pressure state, can not flow to naturally in the blow down tank owing to be lower than the barometric pressure of outside, this valve also plays the function of external blowdown simultaneously;
Draw pipeline three from compressor secondary suction tude (also being the one-level outlet pipe) and be connected on the blow down tank, installation and control valve three on it when its objective is compressor operating, provides greater than the outer atmospheric gas pressure of blow down tank to discharge jar interior ponding.
The beneficial effect of the utility model provides a kind of gas pressure that utilizes after the compressor compresses, as the blowdown power of negative pressure, barometric pressure, slight positive pressure state down blow point, reaches the purpose of blowdown, arranges thereby solve the dirt of compressor under above state; This apparatus structure is simple, reliability is high, and is safe and practical, and macroeconomy property improves a lot.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings:
Fig. 1 is the plan view of the utility model.
Embodiment
As shown in Figure 1, the compressor drainage device at the utility model negative pressure, barometric pressure, micro positive pressure place comprises blow down tank 7; Blow down tank 7 is communicated with preceding liquid/gas separator 1 through pipeline 1, and pipeline 1 is provided with control valve 1, and blow down tank 7 is communicated with one-level cylinder block 4 through pipeline 23; Pipeline 23 is provided with control valve 26, and blow down tank 7 is communicated with secondary suction tude 11 through pipeline 3 10, and pipeline 3 10 is provided with control valve 39; Blow down tank 7 is provided with sewage draining exit, on sewage draining exit, is provided with control valve 48.
Specific operation are:
A, when compressor operating; Control valve 39 in the drainage, control valve 48 will be in closed condition and control valve 1, control valve 26 are in opening state, and liquid/gas separator 1 is separated before so just making water and the water in the first-stage cylinder seat 4 flow in the blow down tank 7 naturally;
B, current liquid/gas separator is in service will carry out blowdown the time; At first close the control valve 1, the control valve 26 (its objective is and cut off) that are communicated with preceding liquid/gas separator 1, first-stage cylinder seat 4 because the air-breathing influence that blowdown is caused; Open the control valve 39 (its objective is the Driving force that blowdown is provided) that is communicated with the secondary suction tude; And then open control valve 48, can carry out blowdown.After blowdown finished, at first closed control valve 48, and closed control valve 39 is opened control valve 1, control valve 26 then simultaneously, and the blowdown at preceding liquid/gas separator 1 place finishes.In like manner, when first-stage cylinder seat 4 will carry out blowdown operation, programmed sequence of operations was the same;
The horizontal position that c, blow down tank are laid must be lower than preceding liquid/gas separator 1, first-stage cylinder seat 4 is put dirty interface position, its objective is when making compressor operating, more than the sewage at two places can flow in the blow down tank naturally.
