Manufacturing method of waste heat utilization system for PVC glove production

- Feb 20, 2021-

Background technique:


In the production process of pvc gloves, a large amount of waste heat will be generated during the operation of the heat-conducting oil furnace and the baking of the gloves. The lithium bromide refrigerator is also used to treat the waste gas generated in the production of pvc gloves. At present, the common method in the industry is to rely on a separate cooling tower. To cool the organic waste gas, the large amount of heat energy discharged from the workshop cannot be fully recycled, resulting in a huge waste of energy.

Technical realization elements:


The purpose of the utility model is to propose a waste heat utilization system for the production of pvc gloves, which uses the waste heat produced by the equipment during the production of pvc gloves for heating and cooling of the office area, so as to meet the demand for cold and heat in summer and winter and reduce the purchase of enterprises. Heating and cooling costs.


The waste heat utilization system for pvc glove production of the utility model includes a flue gas heat exchanger, a gas waste heat boiler, a lithium bromide refrigerator, a hot water separator, a hot water collector and a plumbing air conditioner. The flue gas heat exchanger The heat exchange outlet pipe and the heat exchange outlet pipe of the gas waste heat boiler merge together, and are connected to the heat source inlet pipe of the lithium bromide refrigerator through the first branch pipe, and are connected to the hot water separator inlet pipe through the second branch pipe, and the hot water separator outlet pipe After heat exchange through the plumbing and air conditioning, it enters the return pipe of the hot water collector. The return pipe of the hot water collector merges with the return pipe of the lithium bromide refrigerator and is connected to the heat exchange inlet pipe of the gas waste heat boiler through the third branch pipe, and passes through the fourth branch pipe Connect with the heat exchange inlet pipe of the flue gas heat exchanger.


Said, it also includes a water-cooled air conditioner, the lithium bromide refrigerator refrigerant outlet pipe is connected with the water-cooled air conditioner inlet pipe, and the water-cooled air conditioner outlet pipe is connected with the lithium bromide refrigerator refrigerant return pipe.

Said, valve switches are provided on the first branch pipe, the second branch pipe, the third branch pipe and the fourth branch pipe.


Working principle and process: When it is cold in summer, the waste heat produced by the flue gas heat exchanger and the gas waste heat boiler is transferred to the lithium bromide refrigerator through the heat exchange outlet pipe, and the lithium bromide refrigerator provides the cooling heat source for the lithium bromide refrigerator. The lithium bromide absorption chiller is used, and the cooled waste heat circulating water is returned to the flue gas heat exchanger and the gas waste heat boiler heating cycle for reuse. The refrigerant outlet pipe of the lithium bromide refrigerator is connected with the water-cooled air conditioner inlet pipe, and the water-cooled air conditioner cools the office area After consuming the cooling capacity, the circulating water returns to the flue gas heat exchanger and gas waste heat boiler for recycling; when heating in winter, switch the valves of the first branch, second branch, third branch, and fourth branch to make the flue gas The waste heat produced by the heat exchanger and the gas waste heat boiler passes through the heat exchange outlet pipe and transfers the heat to the hot water separator with medium water. After the office area is heated by the plumbing and air conditioning, the waste heat is collected by the hot water collector, and the heat after the heat is consumed The water is returned to the flue gas heat exchanger and gas waste heat boiler for recycling. When heating in winter, close the valve switches on the first branch and the third branch; when it is cold in summer, close the valve switches on the second branch and the fourth branch. .


The beneficial effects of the utility model are: make full use of the waste heat generated by the flue gas heat exchanger and the gas waste heat boiler during the production of pvc gloves, and provide a cooling heat source for the lithium bromide refrigerator when it is cold in summer, thereby reducing energy consumption and saving electricity; When heating in winter, water heating and air conditioning are used to heat the office area to meet the demand for cold and heat in summer and winter and reduce the cost of heating and cooling for enterprises.
