Abstract
The utility model discloses a deaerator exhaust steam recycling device, which comprises a deaerator and a recycling device arranged in the deaerator, wherein the recycling device comprises a vertical pipe connected with an auxiliary heater of the deaerator and a horizontal pipe connected with the vertical pipe; the transverse pipe is provided with a plurality of air holes. This device retrieves the exhaust steam of other parts through the pipeline, and inside the oxygen-eliminating device auxiliary heater got into the oxygen-eliminating device again, the drainage through the standpipe got into the violently pipe that is located the oxygen-eliminating device bottom, gives off through the gas pocket on violently managing, because the pressure variation of in-process exhaust steam can give out the heat, utilizes this heat to heat for the oxygen-eliminating device, can effectually reduce the oxygen-eliminating device to the needs of high temperature high pressure saturated steam, recycles the recovery exhaust steam simultaneously, the effectual energy of having practiced thrift.
Description
Technical Field
The utility model relates to a boiler equipment technical field, specific theory is a deaerator exhaust steam recycle device.
Background
The deaerator has the working principle that saturated steam feed water is heated to the saturation temperature corresponding to the working pressure of the deaerator, oxygen and other gases dissolved in the feed water are removed, and corrosion of a boiler feed water pipe, an energy saver and other auxiliary equipment is prevented and reduced. Has the characteristics of stable operation, high deoxidization efficiency, good adaptability and the like. But the heating heat source of the deaerator is totally from high-temperature high-pressure saturated steam generated by a boiler. Belongs to the large 'internal consumption' equipment of a steam system. Can basically occupy about 15 to 20 percent of steam consumption.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a deaerator exhaust steam recycle device for solve among the prior art the heating heat source of deaerator all come from the higher problem of high temperature high pressure saturated steam internal consumption that the boiler produced.
The utility model discloses a following technical scheme solves above-mentioned problem:
a deaerator exhaust steam recycling device comprises a deaerator and a recycling device arranged in the deaerator, wherein the recycling device comprises a vertical pipe connected with an auxiliary heater of the deaerator and a horizontal pipe connected with the vertical pipe; the transverse pipe is provided with a plurality of air holes. This device retrieves the exhaust steam of other parts through the pipeline, and inside the oxygen-eliminating device auxiliary heater got into the oxygen-eliminating device again, the drainage through the standpipe got into the violently pipe that is located the oxygen-eliminating device bottom, gives off through the gas pocket on violently managing, because the pressure variation of in-process exhaust steam can give out the heat, utilizes this heat to heat for the oxygen-eliminating device, can effectually reduce the oxygen-eliminating device to the needs of high temperature high pressure saturated steam, recycles the recovery exhaust steam simultaneously, the effectual energy of having practiced thrift.
Preferably, the standpipe divide into two sections at least, through flange joint between the adjacent section, if the standpipe be whole section then probably can not directly get into the inside installation that carries out of oxygen-eliminating device because of the reason of length, consequently segment the standpipe, then get into the inside installation that carries out of oxygen-eliminating device, for the convenience of the connection between the standpipe, set up the flange in the junction.
Preferably, the lower part of violently managing is equipped with 1 at least support, and the main effect of support is supported violently the pipe with oxygen-eliminating device bottom contact, simultaneously because the support can make violently the air pocket of managing the bottom keep the clearance with the oxygen-eliminating device and let the air pocket ventilate, improves heating efficiency, because violently the pipe links to each other with the standpipe, has a strong point, so only need in violently the proper position installation of pipe lower part support can.
Preferably, the number of the brackets is 2, and the brackets are respectively positioned at two ends of the transverse pipe.
Preferably, the auxiliary heater is connected with at least one flash tank, and each flash tank is respectively arranged on each exhaust steam recovery pipeline.
Preferably, the pore diameter of the pores is not less than 0.5 cm.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
(1) the utility model discloses a retrieve the exhaust steam, then leading-in oxygen-eliminating device is inside to heat the oxygen-eliminating device, can effectually reduce the needs of oxygen-eliminating device to high temperature high pressure saturated steam, recycles the recovery exhaust steam simultaneously, the effectual energy of having practiced thrift.
(2) The utility model discloses be equipped with the support in the lower part of violently managing, make its bottom with the oxygen-eliminating device keep the clearance, let all gas pockets ventilate, promote heating efficiency.
Drawings
FIG. 1 is a schematic structural view of a recycling device of the present invention;
FIG. 2 is a schematic view of the installation structure of the recycling device of the present invention;
in the drawings, the reference numbers: 1-a vertical pipe; 2-a flange; 3-horizontal pipe; 4-pores; 5-bracket.
Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Example 1:
with reference to the attached drawing 1, the exhaust steam recycling device of the deaerator comprises the deaerator and a recycling device arranged in the deaerator, wherein the recycling device comprises a vertical pipe 1 connected with an auxiliary heater of the deaerator and a horizontal pipe 3 connected with the vertical pipe 1; a plurality of air holes 4 are formed in the transverse pipe 3, the aperture of each air hole 4 is not less than 0.5cm, and the air holes are distributed on the pipe wall of the transverse pipe 3; the outside of the auxiliary deaerator is connected with a workshop recovery steam pipeline and a boiler blow-off recovery steam pipeline, and two pipelines are respectively provided with a flash tank.
The vertical pipe 1 is divided into two sections, and because of the limitation of length, the vertical pipe enters the deaerator in two sections instead, and the two sections of vertical pipes 1 are connected by a flange 2. As shown in fig. 2, standpipe 1's both ends respectively with violently manage 3 and oxygen-eliminating device auxiliary heater and be connected, the bottom of violently managing 3 is equipped with two supports 5, be located both ends respectively, this support 5 contacts with the bottom of oxygen-eliminating device, will violently manage 3 bottoms that prop from the oxygen-eliminating device, all gas pockets 4 on the pipe wall of letting violently managing 3 can both ventilate, can promote the rate of giving vent to anger, the efficiency of heating is improved, because violently 3 pipes link to each other with standpipe 1, there has a strong point, so it is equally feasible at a support of the suitable position installation of violently managing 3.
Through the utility model discloses a recycle device retrieves the exhaust steam of other parts, it is inside through oxygen-eliminating device auxiliary heater entering oxygen-eliminating device again, drainage entering through standpipe 1 is located violently pipe 3 of oxygen-eliminating device bottom, give off through violently managing the gas pocket 4 on 3, because the pressure variation of in-process exhaust steam can give out the heat, utilize this heat to heat for the oxygen-eliminating device, can effectually reduce the oxygen-eliminating device to the needs of high temperature high pressure saturated steam, recycle retrieving exhaust steam simultaneously, the effectual energy of having practiced thrift.
