Description

Full-automatic condensate recovery device

The utility model relates to the steam condensate treatment facility in the general hot swapping, is the retracting device of a kind of collection, conveying high temperature (about 130 ℃) condensate water.

As everyone knows, in steam pipe system, the contained heat of condensate water of discharging from drain valve accounts for 20～30% of steam heat.Therefore reclaim and make full use of condensed water in high temperature and be the important and active measure of of energy savings.Both at home and abroad carrying the mode of condensed water in high temperature a lot of to reclaiming, is 87210157.6 " coagulation hydroenergy backwater device " as China Patent No., is a kind of the device of airtight water tank and water pump composition one." OVK " condensate water automatic recycling device of Japan, have a water collect tank, basin, two check-valves, three stop valves, pressurized gas supply pipe and gland steam exhausters etc., steam discharge or pressurization that it utilizes the keg float in the basin body to come actuation means make the device running to reclaim, to carry condensate water.This condensed-water recovering device, its tank structure and manipulation and executing agency are all complicated.With the utility model comparatively approaching be existing a kind of on the market without water pump, and with the monoblock type " steam pressurized reclaim condensate water device " of electromagnetism for control, mainly form by integrally-built tank body, water level controller, admission magnetic valve and exhaust solenoid valve, check-valves and pipeline etc., tank body is separated into collecting chamber and compression chamber, collecting chamber top is provided with normally closed discharge line valve, to get rid of incondensable gas frequently.The action principle of this device is that condensate water is introduced collecting chamber earlier, flows into the compression chamber by communicating pipe then, when water level is raised to peak level in the compression chamber, the admission magnetic valve is promptly opened voluntarily, and pressue device charges into steam by the admission magnetic valve to the compression chamber, and condensate water promptly is forced out; When the water level in the compression chamber is reduced to lowest water level, admission closed electromagnetic valve, steam discharge magnetic valve are opened, steam residual in the compression chamber drains into collecting chamber by gland steam exhauster, makes the pressure in two Room equate that condensate water flows to the compression chamber by collecting chamber again under the effect of static pressure.The water level control sensor of compression chamber is a kind of level electrode or reed switch formula fluid level announciator in this device.The weak point that said steam pressurized reclaims the condensate water device is: in the tank body collecting chamber and compression chamber are set simultaneously, can make the tank structure complexity, influence the condensate water disposal ability, promptly limited the expansion of its separate unit processing capacity; Secondly, the incondensable gas air bleeding valve that is positioned on the collecting chamber needs manual operation, makes enclosed construction can not really realize the enclosed operation, and can lose with indirect steam; Moreover steam electromagnetic valve is the main devices of this no blowback receiving apparatus, and the price of this valve is more expensive, and this retracting device need then both improve cost with two, can not adapt to the requirement of retracting device high-frequency action again, the long-term service life continuously of influence; Because the level electrode in the compression chamber is at its root ceramic seal sealed knot, electrode body and electrode casket housing end face are very approaching, and insulating properties can not guarantee, Yi Fashengyin short circuit and the misoperation that produces.

The utility model provides a three-way magnetic valve control of a kind of usefulness, and can really realize the full-automatic condensed-water recovering device of assembly type that enclosed is moved, make simplified and compactness, it is big that the separate unit condensate water is handled capacity, and the continuous service life of fault-free is long.

For achieving the above object, the utility model on a support with horizontal layout configuration condensed water in high temperature catchment pans and two closed tanks of pressurized delivered jar, with pans last, transfer pot is being provided with down, fuses by pipeline and stop valve, check-valves and three-way magnetic valve or Pneumatic three-way stop valve between two jars.Specifically, condensed water in high temperature catchments and is provided with two water inlets being made up of pipe fittings such as stop valve, check-valves and magnetic valves and pressurization, discharge duct between pans and pressurized delivered jar, inlet channel is made of a stop valve, check-valves and pipeline, pressurization, discharge duct are made of a three-way magnetic valve and exhaust line, three ports of this three-way magnetic valve respectively with pressurization vapour (gas) pipeline, the exhaust line of pans and transfer pot is connected; A check-valves is housed on the condensate water discharge road of transfer pot.For guaranteeing that the utility model reaches the purpose of real closed operation, be provided with can only passing through and indirect steam unpassable drain valve that the emptying form is installed in pans among the design by incondensable gas.Simultaneously, for preventing level electrode generation misoperation, it is a kind of double end control enclosed electrode that can anti-200 ℃ of high temperature that the utility model is arranged on liquid level control electrode in the transfer pot, its main feature is mounted in the sleeve pipe sealing-in that the electrode body in the electrode casket is made with a pair of polytetrafluoroethylene, and a sleeve pipe wherein stretches out in electrode casket housing end face, make the electrode body naked section away from metal shell with prevent electrode in damp and hot space owing to condensate water is tied the short circuit phenomenon that attached extension takes place thereon.

Operation logic of the present utility model is: 1. water filling stage: condensate water flows into transfer pot by gravity through stop valve and a check-valves by the top pans, and this moment, three-way magnetic valve was connected exhaust line (pressure pipeline is closed), the pressure balance between two jars; 2. water delivery stage: when the condensate water in the transfer pot arrives control when high-order, control electrode control three-way magnetic valve changes the position, close exhaust line, open pressure pipeline, pressurization vapour (gas) enters transfer pot, make pressure in the transfer pot surpass the back pressure of discharge pipe line, condensate water enters reclaim line by outlet, till arriving the control electrode low level; 3. balance (steam discharge) stage: three-way magnetic valve recloses exhaust line, closes pressure pipeline, and transfer pot is communicated with pans, and pressure reaches balance between two jars.Device is running continuously again and again as mentioned above.

This shows, the utility model has the advantages that two horizontal closed tanks that are provided with respectively structurally help improving bearing capacity, and are easy to manufacture, be convenient to expand separate unit and handle capacity; Two tank body group devices have the advantage of monolithic construction compactness on same support; Transfer pot fill vapour (gas) and steam discharge can be realized with a three-way magnetic valve, then both simplified control system, provide cost savings again; Be arranged at that drain valve on the pans can be got rid of the incondensable gas in the jar automatically and the discharging that stops indirect steam had then both reduced heat-energy losses, avoided manual bleed air operation again, realize full-automatic enclosed running; The liquid level seals electrode of special construction has prevented the short circuit phenomenon that very easily takes place, and guarantees that transducing signal is accurate, and running is reliable.
