Abstract
The invention belongs to an energy-saving type test run device for a water chilling unit. The energy-saving type test run device comprises a water cooling tower, the water chilling unit, a first cold water pipe, a second cold water pipe, a water inlet pipe of an air cooling tower and the air cooling tower. One end of the water inlet pipe of the air cooling tower is connected with the air cooling tower, and the other end of the water inlet pipe of the air cooling tower is split into two branches, wherein one branch is connected with the lower portion of the water cooling tower through the first cold water pipe, and the other branch is connected with the lower portion of the water cooling tower through the second cold water pipe. The water chilling unit and a low temperature water pump are arranged on the second cold water pipe. The water inlet pipe of the air cooling tower is further connected with a test run pipeline. The bottom of the air cooling tower is connected with a cold water outlet pipe. The water inlet pipe of the air cooling tower is communicated with the cold water outlet pipe through the test run pipeline. A second valve is arranged on the test run pipeline. According to the energy-saving type test run device for the water chilling unit, the test run pipeline is added and installed between the water inlet pipe of the air cold tower and the cold water outlet pipe, so that the operation of an air compressor is not needed when the water chilling unit is being debugged and the energy consumption of the test run of an air separation device is greatly reduced.
Description
Technical field
The invention belongs to technical field of air separation, be specifically related to a kind of energy-saving handpiece Water Chilling Units testing device.
Background technology
Along with socioeconomic development, the application of air separation plant is constantly expanded in recent years, sets foot in as the industries such as petrochemical industry, glass, rubber, building, carbon fiber have.Industry is ever-increasing to the demand of nitrogen and oxygen, also constantly proposes higher requirement to energy-saving and cost-reducing simultaneously.When needing in existing technology to debug handpiece Water Chilling Units, also air compressor machine is needed to open, just can make circulation cold water reflux cycle (because the position of cooling tower generally all arranges higher, when the pressure in air cooling tower is less, the circulation cold water flowed out bottom air cooling tower just can not get back to cooling tower).
Summary of the invention
The object of this invention is to provide the energy-saving handpiece Water Chilling Units testing device that a kind of structure is simple, easy to operate.
For achieving the above object, the technical solution used in the present invention is, a kind of energy-saving handpiece Water Chilling Units testing device, comprises water-cooling tower, handpiece Water Chilling Units, the first cool water pipe, the second cool water pipe, air cooling tower water inlet pipe and air cooling tower; One end of described air cooling tower water inlet pipe is connected with air cooling tower, the other end is divided into two branch roads, one of them branch road is connected with water-cooling tower bottom by the first cool water pipe, and another branch road is connected with water-cooling tower bottom by the second cool water pipe, and the second cool water pipe is provided with handpiece Water Chilling Units and low temperature water pump; Described air cooling tower water inlet pipe is also connected with test run pipeline, and the bottom of air cooling tower is connected with cold water outlet pipe, and air cooling tower water inlet pipe is communicated with cold water outlet pipe by test run pipeline, test run pipeline is provided with the second valve.
Described air cooling tower bottom is connected with compressed air and enters pipe.
Described water-cooling tower bottom is connected with cryogenic gas and enters pipe.
Preferably, described air cooling tower and water-cooling tower are packed tower.
The beneficial effect that the present invention produces is, by installing test run pipeline additional between air cooling tower water inlet pipe and cold water outlet pipe, air compressor need not be run when debugging handpiece Water Chilling Units, greatly save the test run energy consumption of air separation unit, meet the requirement to industrial equipment energy-saving and emission-reduction that country is present, can debug at any time after simultaneity factor has connected, not by the restriction that can air compressor run.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
Detailed description of the invention
