Abstract
The invention discloses a vacuum drier which comprises a circulating water pump, a solenoid valve and a filter, wherein one end of the circulating water pump is arranged on a circulating water pipeline; a water ring vacuum pump, a fourth roots pump and a third roots pump which are connected by air pipelines sequentially are arranged at the other end of the circulating water pump; the other end of the third roots pump is connected with air outlet ends of a first roots pump and a second roots pump respectively by an air pipeline; air inlet ends of the first roots pump and the second roots pump are connected with the filter by an air inlet pipeline; the solenoid valve is arranged on an air pipeline between the fourth roots pump and the water ring vacuum pump; and the roots pumps, the water ring vacuum pump, the circulating water pump and the solenoid valve are connected with a control cabinet by a cable. The vacuum drier can vacuumize a dried pipe, so that water and air in the pipe are removed; the ice blockage and corrosion probability of the pipe is reduced; the service life of the pipe is prolonged; and the vacuum drier is wide in application scope and good in drying effect.
Description
Technical field
The present invention relates to a kind of vacuum drier, particularly a kind of vacuum drier for long distance pipeline and station.
Background technology
In the prior art, long-distance transport pipes need carry out the water pressure test before operation, in pigging process, the water in the pipeline is difficult for being cleaned out, water in the pipeline can cause that corrosive pipeline, hydrate blocking pipe, low temperature ice are stifled etc., has a strong impact on the safe operation of pipeline.At present, a long distance pipeline and station dry air drying method that adopt more, by the mode of dry air with gas displacement in the pipeline, reach dry purpose, but that, pipeline many for pipeline specifications rises and falls is big, there was dampness in the air area and can not lead to the long distance pipeline of ball, moisture in the pipeline is difficult to remove, and therefore, dry air drying method drying effect is relatively poor.General vacuum drier also can only satisfy the less container of volume and pipeline.
Summary of the invention
The purpose of this invention is to provide a kind of applied range, vacuum drier that drying effect is good.
For achieving the above object, the present invention is by the following technical solutions:
Vacuum drier comprises water circulating pump, magnetic valve, filter, and described water circulating pump one end is located on the circulating water pipework, and the other end is provided with water ring vacuum pump, the 4th lobe pump, the 3rd lobe pump that connects by the tracheae line successively; The other end of described the 3rd lobe pump links to each other with the outlet side of first lobe pump with second lobe pump respectively by the tracheae line; The inlet end of described first lobe pump and second lobe pump links to each other with described filter by admission line, and described magnetic valve is located on the tracheae line between the 4th lobe pump and the water ring vacuum pump; Described lobe pump, water ring vacuum pump, water circulating pump, magnetic valve are connected with switch board by cable.
On the connection tracheae line between described first lobe pump, second lobe pump, the 3rd lobe pump, the 4th lobe pump and the water ring vacuum pump first corrugated expansion joint, second corrugated expansion joint, the 3rd corrugated expansion joint and the 4th corrugated expansion joint are installed successively.
On the admission line of described first lobe pump or second lobe pump pneumatic operated valve is installed.
Vacuum drier of the present invention is evacuated by the lobe pump pipeline that will be dried, and water, gas in the pipeline are eliminated, and reduces the stifled and corrosion probability of pipeline ice, prolongs pipeline service life.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Embodiments of the invention, shown in Fig. 1-2: vacuum drier comprises water circulating pump 6, magnetic valve 12, filter 13.Water circulating pump 6 one ends are located on the circulating water pipework 14, and the other end is provided with water ring vacuum pump 5, the 4th lobe pump E-4, the 3rd lobe pump E-3 that connects by the tracheae line successively; The other end of the 3rd lobe pump E-3 links to each other with the outlet side of the first lobe pump E-1 and the second lobe pump E-2 respectively by the tracheae line; The inlet end of the first lobe pump E-1 and the second lobe pump E-2 links to each other with filter 13 by admission line, and magnetic valve 12 is located on the tracheae line between the 4th lobe pump E-4 and the water ring vacuum pump 5; Lobe pump, water ring vacuum pump 5, water circulating pump 6, magnetic valve 12 are connected with switch board by cable.
The first corrugated expansion joint 7a, the second corrugated expansion joint 7b, the 3rd corrugated expansion joint 7c and the 4th corrugated expansion joint 7d are installed on the connection tracheae line between the first lobe pump E-1, the second lobe pump E-2, the 3rd lobe pump E-3, the 4th lobe pump E-4 and the water ring vacuum pump 5 successively; Can effectively avoid equipment in operation process, because of variations in temperature, make to connect tracheae line generation stretching or compression stress, cause the generation of device damage accident.
Pneumatic operated valve 8 is installed on the admission line of the first lobe pump E-1, by opening and closing pneumatic operated valve 8, can realizes unit or the duplex running of the first lobe pump E-1 and the second lobe pump E-2, satisfy the dry requirement of different stations or pipeline.
The present invention can be installed in the skid, is convenient to transportation and execute-in-place.
When needs carry out station or pipeline drying, filter 13 of the present invention is connected with pipeline flange to be dried, start 6 pairs of lobe pumps of water circulating pump by switch board, water ring vacuum pump 5 cools off, restart water ring vacuum pump 5, as the first lobe pump E-1, the second lobe pump E-2, the 3rd lobe pump E-3, pressure reduction between the 4th lobe pump E-4 reaches when setting the startup value, open the 4th lobe pump E-4 successively, the 3rd lobe pump E-3, the second lobe pump E-2 and sieve first thatch pump E-1, the pipeline that will be dried is evacuated, can be with the water in the pipeline, gas is removed, reduce the stifled and corrosion probability of pipeline ice, prolong pipeline service life.
