Abstract

A vapor-recovery device for air separation equipment is composed of a water tank and a vapor recovery heat exchanger. A vapor condensing pipe of the vapor recovery heat exchanger is arranged in an outer sleeve, two ends of the outer sleeve are connected with a cooling water inlet pipe and a cooling water outlet pipe respectively, and two ends of the vapor condensing pipe are connected with a molecular sieve vapor discharging pipe and a water tank water inlet pipe respectively. A water tank water outlet pipe is connected with a water washing tank of an air compressor vane wheel. A water pump is arranged on the water tank water outlet pipe, a water pump outlet pipe is connected with the water washing tank of the air compressor vane wheel and a water cooling tower respectively, and liquid level control water charging valves are arranged on the water pump outlet pipe and a water cooling tower connecting pipe. The water cooling tower is connected with the water tank through a water pipe, and a liquid level control reflux valve is arranged on the water pipe. By means of the vapor-recovery device, discharged vapor of a heating molecular sieve can be cooled and recovered to make into distilled water so as to supply for the water washing tank of the air compressor vane wheel, so that money used for outsourcing the distilled water is saved and production cost is reduced.

Description

The vapour-recovery unit that is used for air separation plant
Technical field:
The utility model relates to a kind of device that reclaims air separation plant in molecular sieve heating period discharged steam, belongs to sky dispenser sleeve equipment technical field.
Background technology:
In industrial production, a lot of enterprises adopt air separation equipment system oxygen, system nitrogen, and a whole set of air separation plant comprises auxiliary devices such as air compressor machine, chilldown system, molecular sieve, decompressor, fractionating column, product compressor.Need a large amount of distilled water in process of production on the one hand, impeller as air compressor machine will carry out the water flushing, need outsourcing distilled water, dividing nitrogen water chilldown system with space-time is closed cycle, water the circulation process in along with loss, hardness and acidity can concentrate rising, wall thickness to equipment produces certain corrosion, and the fault of leaking in can taking place when serious must be carried out soft water and be replenished, could normally move by support equipment, required soft water also is outsourcing other unit soft water, according to measuring and calculating, only purchases surplus the expense needs 20 of distilled water ten thousand yuan the whole year once cover molecular sieve flow process oxygen generating plant, take a large amount of funds, improved production cost; But then, thermal source required when regenerating molecular sieve heats adopts heating means at interval all from superheated steam, whole day accumulative total heat time heating time 9-12 hour, per hour steam flow be the 2.1-2.5 ton/hour, heating steam by after be discharged in the atmosphere, all wasted.If the Steam Recovery of these dischargings can be made distilled water and is replenished the needs of producing, then can save a large amount of funds, reduce production cost.
Summary of the invention:
The vapour-recovery unit that is used for air separation plant that the superheated steam of discharging was recycled when the utility model provided a kind of regenerating molecular sieve can the heating.
The utility model is achieved by the following technical solution: a kind of vapour-recovery unit that is used for air separation plant, its major technique feature is that it is made up of water tank, Steam Recovery heat exchanger, the steam condenser pipe of Steam Recovery heat exchanger is contained in the outer sleeve, the outer sleeve two ends connect cooling water inlet pipe and cooling water outlet pipe respectively, the steam condenser pipe two ends connect molecular sieve steam discharge pipe and tank inlet pipe respectively, and the tank drains pipe is connected with air compressor machine impeller water flush box; On the tank drains pipe water pump is arranged, pump drain pipe is connected with water-cooling tower with air compressor machine impeller water flush box respectively, and liquid level control water compensating valve is arranged on pump drain pipe and the water-cooling tower tube connector; Also have water pipe to be connected between water-cooling tower and the water tank, liquid level control return valve is arranged on water pipe.
After adopting the utility model, the discharged steam of heating molecular sieve can be cooled off recovery, make distilled water and supply with the use of air compressor machine impeller flush box, the fund of having saved outsourcing distilled water has reduced production cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Sign is as follows among the figure: molecular sieve 1, water tank 2, Steam Recovery heat exchanger 3, steam condenser pipe 4, outer sleeve 5, cooling water inlet pipe 6, cooling water outlet pipe 7, water pump 8, water-cooling tower 9, liquid level control water compensating valve 10, liquid level control return valve 11, air compressor machine impeller water flush box 12
As shown in Figure 1, this device is made up of water tank 2, Steam Recovery heat exchanger 3.Steam Recovery heat exchanger 3 comprises steam condenser pipe 4 and outer sleeve 5, water-filling in the outer sleeve 5, its two ends connect cooling water inlet pipe 6, cooling water outlet pipe 7 respectively, steam condenser pipe 4 is contained in the outer sleeve 5, the two ends of steam condenser pipe 4 connect molecular sieve 1 steam discharge pipe and water tank 2 water inlet pipes respectively, and water tank 2 drainpipes are connected with air compressor machine impeller water flush box 12.On water tank 2 drainpipes, water pump 8 is arranged, water pump 8 drainpipes are connected with water-cooling tower 9 with air compressor machine impeller water flush box 12 respectively, liquid level control water compensating valve 10 is arranged on water pump 8 drainpipes and water-cooling tower 9 tube connectors, also have water pipe to be connected between water-cooling tower 9 and the water tank 2, liquid level control return valve 11 is arranged on water pipe.
Its course of work is: before molecular sieve 1 heating, cooling water is fed Steam Recovery heat exchanger 3, the Steam Recovery valve is opened.After the molecular sieve 1 heating beginning, be condensed into water behind steam importing Steam Recovery heat exchanger 3 and the recirculated cooling water heat-shift and enter water tank 2.Water tank 2 is provided with water pump 8 and starts minimum liquid level, when the normal water pump of water liquid level possesses entry condition, start water pump 8 to water-cooling tower 9 moisturizings, rate of water make-up is regulated according to the water-cooling tower liquid level, because water-cooling tower 9 moisturizings are interrupted, so when water-cooling tower 9 did not need moisturizing, liquid level control return valve 11 was opened automatically, water is returned water tank 2, when water-cooling tower 9 water levels hang down, liquid level control return valve 11 cuts out automatically, and liquid level control water compensating valve 10 is opened automatically, to water-cooling tower 9 moisturizings.When air compressor machine impeller water flush box 12 water levels are low, manual unlocking liquid level control water compensating valve 10 is to 12 moisturizings of air compressor machine impeller water flush box, the valve opening size is fixed according to water-cooling tower 9 moisturizing situations, when water-cooling tower 9 rate of water make-ups are little, valve or suitably open big, when water-cooling tower 9 rate of water make-ups were big, valve or suitably open forr a short time guaranteed water-cooling tower 9 rate of water make-ups.
