Abstract
The utility model discloses a kind of molecular sieve heater condensate drum interlock control system, it comprises and is arranged on liquid level gauge on condensate drum and fluid pipeline, described drain line is provided with successively and sends stop valve, Liquid level adjusting valve, refluence stop valve outside, sends check (non-return) valve outside; To the described fluid pipeline sent outside between stop valve, be provided with discharging tube at described condensate drum, described discharging tube is provided with showering guilding valve; The pipeline of described showering guilding valve rear end is respectively equipped with manual drain valve and dump valve, and described dump valve is electrically connected with described liquid level gauge.Advantage is: prevent molecular sieve heating process, and heater condensate drum liquid level is high, and condensate liquid cannot be sent outside, and regeneration " heating " effect is bad, causes molecular sieve adsorption deleterious.
Description
Technical field:
The utility model relates to a kind of automatic control system, particularly relates to a kind of molecular sieve heater condensate drum interlock control system.
Background technology:
Owing to needing by middle pressure steam " heating " desorb when molecular sieve activation regenerates, the condensate liquid of generation concentrates in condensate drum, utilizes steam pressure to be sent outside by Liquid level adjusting valve by the condensate liquid in condensate drum.If Liquid level adjusting valve breaks down, or Liquid level adjusting valve is switched to " manually " position when a certain small guide vane by operative employee from " automatically " position by mistake, " heating " temperature does not reach requirement, and cause molecular sieve activation to regenerate " heating " bad, carbon dioxide, the water of absorption do not desorb completely.When molecular sieve adsorbs before being switched to next week, outlet carbon dioxide exceeds standard, and brings hidden danger to distillation system.
Utility model content:
The purpose of this utility model is to provide one to prevent molecular sieve heater condensate drum liquid level high, reduces the molecular sieve heater condensate drum interlock control system of molecular sieve activation regeneration effect
The utility model is implemented by following technical scheme: molecular sieve heater condensate drum interlock control system, it comprises and is arranged on liquid level gauge on condensate drum and fluid pipeline, described drain line is provided with successively and sends stop valve, Liquid level adjusting valve, refluence stop valve outside, sends check (non-return) valve outside; To the described fluid pipeline sent outside between stop valve, be provided with discharging tube at described condensate drum, described discharging tube is provided with showering guilding valve; The pipeline of described showering guilding valve rear end is respectively equipped with manual drain valve and dump valve, and described dump valve is electrically connected with described liquid level gauge.
Advantage of the present utility model: prevent molecular sieve heating process, heater condensate drum liquid level is high, and condensate liquid cannot be sent outside, and regeneration " heating " effect is bad, causes molecular sieve adsorption deleterious.
Accompanying drawing illustrates:
Fig. 1 is overall schematic of the present utility model.
Condensate drum 1, liquid level gauge 2, fluid pipeline 3, send stop valve 4, Liquid level adjusting valve 5, refluence stop valve 6 outside, send check (non-return) valve 7, discharging tube 8, showering guilding valve 9, manual drain valve 10, dump valve 11 outside.
Detailed description of the invention:
As shown in Figure 1, molecular sieve heater condensate drum interlock control system, it comprises and is arranged on liquid level gauge 2 on condensate drum 1 and fluid pipeline 3, drain line 3 is provided with successively and sends stop valve 4, Liquid level adjusting valve 5, refluence stop valve 6 outside, sends check (non-return) valve 7 outside; To the fluid pipeline 3 sent outside between stop valve 4, be provided with discharging tube 8 at condensate drum 1, discharging tube 8 is provided with showering guilding valve 9; The pipeline of showering guilding valve 9 rear end is respectively equipped with manual drain valve 10 and dump valve 11, and dump valve 11 is electrically connected with liquid level gauge 2.
Operation instruction: manual drain valve 10, as the bypass of dump valve 11, is closed time normal; Showering guilding valve 9 keeps often opening, and dump valve 11 is electrically connected with liquid level gauge 2, interlocked control, and when liquid level gauge 2 reaches 70%, dump valve 11 is opened, and when liquid level gauge 2 is below 50%, dump valve 11 cuts out, and closes time manual drain valve 10 is normal; Avoid and only have showering guilding valve in case of emergency the very first time may not open and discharge on the spot, cause molecular sieve heater condensate drum liquid level high.
Explanation of nouns:
Molecular sieve: molecular sieve wettability power is extremely strong, for the purification process of gas, should avoid during preservation being directly exposed in air.The resting period longer and molecular sieve of moisture absorption should regenerate before using.Molecular sieve avoids oil and aqueous water.Should avoid during use contacting with oil and aqueous water as far as possible.In industrial production, the gas of dry process has, air, oxygen,
nitrogen,
argon gasdeng. with two absorption
drierparallel connection, a job, another can carry out regeneration process simultaneously.Mutual alternation and regeneration, to ensure that equipment runs continuously.Drier works at normal temperatures, in qi of chong channel ascending adversely regeneration to 300 DEG C of heating.
Activating and regenerating: molecular sieve, after saturated absorption moisture, carbon dioxide, needs, through activating and regenerating, to be desorbed by adsorbate, can again come into operation.Molecular sieve after correct regeneration with fresh, the decay of its absorption property and mechanical strength and aging be low-down.The mode of molecular sieve activation regeneration is high-temperature low-pressure.
