Description

Technical Field

[0001] The utility model relates to the technical field of air separation process, in particular to a large-scale air separation circulating water system. Background Art

[0002] A large amount of heat is generated during the operation of the compressor in the air separation process. In order to ensure the continuous production, the generated compression heat needs to be replaced. The main equipment for heat replacement is the intercooler. The cooling effect of the cooler determines whether the process production can be carried out continuously and whether the energy consumption during operation is economical. The cold source of the cooler is circulating water, so the quality of circulating water is one of the main indicators affecting the operation effect of the cooler.

[0003] At present, the mainstream filtering method for circulating water impurities is to install a metal filter at the inlet of the water pump. In this scheme, if the number of filter meshes is low, the purpose of filtering solid particles cannot be achieved; if the number of filter meshes is high, solid particles are likely to block the inlet of the water pump, generating negative pressure, causing cavitation of the water pump, and unable to establish water pressure and other process events; and the existing filter mechanism is inconvenient to remove impurities inside, and has poor practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a large-scale air separation circulating water system, which has the advantages of double filtration, avoidance of blockage and convenient impurity removal, strong practicality, and solves the problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large-scale air separation circulating water system, comprising a cylinder, an inner cylinder and a bracket, a partition is fixed in the middle of the cylinder, a cone is fixed at the upper end of the cylinder, and a conduit is installed through the lower end of the cone, the inner cylinder is sleeved and fixed in the middle of the conduit, and the outer side of the inner cylinder fits the inner wall of the cylinder, coarse filter screens are embedded and installed on both sides of the cone, a fine filter screen is provided on the lower end surface of the inner cylinder, a pressure cover is provided in the upper end recess of the cone, the bracket is fixed at the bottom end of the cylinder, and a second electric telescopic rod is fixed on the upper side of the bracket, and a sealing plate is provided at the lower end opening of the cylinder.

[0006] When a large-scale air separation circulating water system in the technical solution is used, the circulating water is introduced into the upper side of the cone cylinder at the top of the cylinder through the liquid inlet pipe, and the circulating water is preliminarily filtered through the coarse filter screen to filter out the large particles of impurities inside. Due to the conical inclined surface design of the cone cylinder, the impurities are gathered at the bottom, and the circulating water passes through the coarse filter screen and falls into the built-in cylinder. After secondary filtration through the fine filter screen, it is introduced into the upper side of the partition plate and then discharged outward through the liquid discharge pipe. Impurities are removed regularly, and the second electric telescopic rod is started to drive the pressure cover to rise. After the pressure cover is opened, the particulate impurities are introduced into the upper side of the sealing plate at the bottom through the conduit, and then the first electric telescopic rod is started to drive the sealing plate to descend to discharge the particulate impurities.

[0007] Preferably, a leg is fixed to the lower end of the outer side of the cylinder, and there are four legs in total, and the four legs are distributed in a circular array, and an anti-skid pad is fixed to the lower end of the leg. The cylinder is placed and supported by the legs, and the anti-skid pad increases friction to ensure support stability.

[0008] Preferably, the lower end of the conduit passes through the middle of the partition, and the upper end opening of the conduit is matched with the gland. After the gland is separated from the upper end opening of the conduit, the granular impurities gathered in the upper notch of the cone cylinder pass through the conduit and are discharged downward.

[0009] Preferably, the upper end of the second electric telescopic rod passes through the inner side of the conduit and is fixed on the gland. The gland is driven to rise and fall by the second electric telescopic rod.

[0010] Preferably, a first electric telescopic rod is fixed to the lower side of the bracket, and the lower end of the first electric telescopic rod is fixed to the sealing plate. The sealing plate is driven to rise and fall by the first electric telescopic rod.

[0011] Preferably, a drain pipe is installed through the front end surface of the cylinder, and the inner end of the drain pipe is connected to the upper side of the partition. The circulating water in the upper space of the partition is discharged outward through the drain pipe.

[0012] Preferably, a top cover is provided at the upper opening of the cylinder, and a liquid inlet pipe is installed through the middle of the upper end surface of the top cover. The detachable top cover facilitates device maintenance, and circulating water is introduced into the device through the liquid inlet pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the operator starts the device through an external control device and supplies power to the external power supply, and introduces the circulating water into the upper side of the cone cylinder at the top of the cylinder through the liquid inlet pipe, and performs preliminary filtration on the circulating water through the coarse filter screen to filter out the large particles of impurities inside. Due to the conical inclined surface design of the cone cylinder, the impurities gather at the bottom, and the circulating water passes through the coarse filter screen and falls into the built-in cylinder. After secondary filtration through the fine filter screen, it is introduced into the upper side of the partition plate, and then discharged outwardly through the liquid discharge pipe. Impurities are removed regularly, and the second electric telescopic rod is started to drive the pressure cover to rise. After the pressure cover is opened, the particulate impurities are introduced into the upper side of the sealing plate at the bottom through the conduit, and then the first electric telescopic rod is started to drive the sealing plate to descend to discharge the particulate impurities. The device has a simple structure and is easy to operate. The filtration quality is ensured through double filtration to avoid clogging by impurities affecting use. At the same time, the convenient impurity removal design reduces the difficulty of operating the device and ensures practicality. BRIEF DESCRIPTION OF THE DRAWINGS
