The lower end water outlet of the cooling tower is equipped with strainer and is equipped with blowdown valve in lower end surface bottom.
The nitriding furnace has been arranged in rows multiple, is connected with multiple bypass lines simultaneously on the cooling tube and the return pipe Connect one to one the nitriding furnace, and pipeline main valve, the bypass line are respectively connected on the cooling tube and the return pipe On be respectively connected with cooling valve and back-water valve (BWV).
The pond includes intake pool and back pool, is separated between the intake pool and back pool by wallboard and in lower end Strainer and blowdown valve are installed, are connected with moisturizing pipeline and water compensating valve on the exterior wall of the back pool.
Water level monitor is connected on the interior pool wall of the intake pool, the water level monitor connects institute by control unit State water compensating valve.
The beneficial effects of the utility model are:
1) the utility model is laid on above gantry using circulation pipeline from high-altitude, has saved ground space, row Except security risk, and easy to operate, easy to repair and maintenance, while water scale discharge is more thorough.
2) the utility model, so that water filtration is more thorough, is kept away by the way of cooling tower and pond double filtration sedimentation The case where having exempted from the impurity corrosion equipment in sewage, extends system service life, increases system run all right.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is made further explanation in the following with reference to the drawings and specific embodiments:
Referring to Fig. 1, in figure, 1- cooling tower, 2- pipeline, 21- water inlet pipe, 22- cooling tube, 23- return pipe, 3- circulating pump, The pond 4-, 41- intake pool, 42- back pool, 43- moisturizing pipeline, 44- water compensating valve, 5- nitriding furnace, 6- gantry, 7- pipeline main valve, 71- cools down valve, 72- back-water valve (BWV).
Embodiment: a kind of nitriding furnace cooling water recirculation system connects nitrogen by cooling tower 1, pipeline 2, circulating pump 3 and pond 4 Change furnace 5 to form, cooling tower 1 is mounted on above gantry 6, and pipeline 2 includes water inlet pipe 21, cooling tube 22 and return pipe 23, cooling tower 1 Upper end water inlet connection water inlet pipe 21, lower end water outlet connect cooling tube 22, circulating pump 3, water inlet pipe are connected on water inlet pipe 21 21 water inlet end connects pond 4, and cooling tube 22 and return pipe 23 are fixedly connected on the support frame of gantry 6 by pipeline folder, Water inlet connection cooling tube 22, the water outlet of nitriding furnace 5 connect return pipe 23, are connected with circulating pump 3, return pipe on return pipe 23 23 water outlet connects pond 4, and nitriding furnace 5 and pond 4 are arranged on ground.
