Abstract

The utility model relates to a low-pressure steam continuous boosting device, composed of a plurality of groups of Rafael nozzles, a pressure sensor, a control computer and an electric regulating valve. The utility model is characterized in that the Rafael nozzles are arranged in a mixed boosting pipe, a high-pressure steam distribution pipe is also arranged at the outer side of the mixed boostingpipe, wherein the steam inlet of the high-pressure steam distribution pipe is connected with a high-pressure steam supply pipe; a high-pressure steam header pipe is connected between the mixed boosting pipe and the high-pressure steam distribution pipe and then connected with the Rafael nozzles inside the mixed boosting pipe through the electric regulating valve. Therefore, under the continuous pressure boosting of the Rafael nozzles, the pressure of the low-pressure steam is greatly increased to meet the production requirement, such that a large amount of low-pressure steam unavailable is changed to high-pressure steam that can meet the production requirement. The utility model has the advantage that a large amount of waste low-pressure steam, including the heat from low-temperature hostwater steam, is utilized, so as to reduce the use amount of steam, save the operation cost and reduce the discharge pollution.

Description

Low-pressure steam continuous pressurizing device

Technical field

The utility model relates to the energy-conserving and environment-protective field, specifically is a kind of low-pressure steam continuous pressurizing device.

Background technique

At present, in industrial steam depressurized system, generally adopt valve to carry out throttling, after the throttling of high pressure (high-grade) steam, in industrial production, use the hot spot air feed.Vapour condensation water after the heat transmission equipment heat exchange directly discharges mostly or only carries out simple heat recovery, and the condensed water mean temperature has been wasted a large amount of energy like this greater than 80 ℃.

The model utility content

It is power with the high compressed steam that the technical problem that the utility model solved is to provide a kind of, low-pressure steam pressure is brought up to be higher than the low-pressure steam continuous pressurizing device of low-pressure steam pressure more than one times.

The technical solution adopted in the utility model is a kind of low-pressure steam continuous pressurizing device, it draws valve that nozzle, pressure transducer, control computer and electric control valve to constitute by many groups, it is characterized in that: described your nozzle of valve that draws is installed in the mixed pressure inlet, the outside at described mixing pressure inlet also is equipped with the high compressed steam gas-distribution pipe, and wherein the suction port of high compressed steam gas-distribution pipe links to each other with the high compressed steam air supply pipe.

Between described mixing pressure inlet and high compressed steam gas-distribution pipe, connect the high compressed steam house steward, be connected with the valve that nozzle that draws in the mixed pressure inlet by electric control valve.

Described pressure transducer is installed in and is used to monitor the come out force value of steam of air supply opening on the air supply opening that mixes pressure inlet.

To be high compressed steam by electric control valve enter working principle of the present utility model draws your nozzle of valve that steam velocity is raise, and pressure descends, and this flow process belongs to the adiabatic expansion process.Owing to draw your nozzle outlet pressure of valve very low, thereby can the very low low-pressure steam of swabbing pressure, through the mixing pressure inlet working steam at a high speed and low pressure gas are mixed equably and reach mixing pressure inlet aditus laryngis place, the mixed gas that makes reaches local velocity of sound, this gas is through diffuser then, because the section of diffuser changes from small to big, the speed of gas then from large to small, reverse pressure is raise by low, this process belongs to the adiabatic compression process, make the lower low-pressure steam of pressure under the above-mentioned effect of high compressed steam, pressure raises, and taste improves.Draw under the continuous supercharging of your nozzle of valve in many groups like this, the pressure of low-pressure steam increases substantially to satisfy and produces needs, the low-pressure steam that can not use is in a large number become can satisfy the GOOD TASTE steam of producing needs.

The beneficial effects of the utility model are owing to utilized the low-pressure steam of a large amount of wastes, comprise the heat of low-temperature water heating flashed vapour, thereby have reduced the use amount of steam, have saved running cost, have reduced exhaust emission.

Description of drawings

Fig. 1 is the structural representation of the utility model low-pressure steam continuous pressurizing device.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, low-pressure steam continuous pressurizing device, install three groups and draw valve that nozzle 1,1 ', 1 " and pressure transducer 2, control computer 3 and three groups of

electric control valves

During operation, high compressed steam enters high compressed steam gas-distribution pipe 6, high compressed steam enters through electric control valve 4 and draws valve that nozzle 1, acceleration and pressure decrease in nozzle, pressure be reduced to be lower than mix low-pressure steams in the pressure inlet low-pressure steam suction port 12 pressure, low-pressure steam is inhaled into the locality is mixed and is accelerated at aditus laryngis 9 places with high compressed steam velocity of sound, slow down at diffuser 11 places then, pressure raises, after pressure raises the low-pressure steam mixed gas under the effect of drawing your nozzle 1 ' of valve, be inhaled into aditus laryngis 9 ' and locate and be accelerated to local velocity of sound, locate to slow down at diffuser 11 ' then, pressure raises, low-pressure steam mixed gas after pressure raises is drawing your nozzle 1 of valve " effect under be inhaled into aditus laryngis 9 " locate and be accelerated to local velocity of sound, then at diffuser 11 " in slow down; pressure is elevated to and is higher than more than a times of low-pressure steam pressure, produces required vapor tension to satisfy.Control computer 3 detects and the signal of processing pressure sensor 2 constantly, and at any time to three groups of

electric control valves

4,4 ', 4 " the output control signal; adjust three groups of

electric control valves

4,4 ', 4 " aperture, stablize the stable of air supply opening 10 place's vapor tensions, circulate so always.
