Background
At present, in the domestic hazardous waste incineration industry, a large amount of low-temperature and low-pressure steam at the temperature of 150-200 ℃ is not utilized, and because no waste heat recovery equipment suitable for the low-temperature and low-pressure steam exists at present, the low-temperature steam must be cooled and condensed into water through an air cooler and then discharged or reused, so that a large amount of heat waste and electric energy loss are caused. Like products in the market can only be applied to high-temperature high-pressure steam, the service life can be greatly shortened when the similar products are used under the condition of low-temperature low-pressure steam, and the efficiency is greatly reduced, so that the existing hazardous waste incineration industry basically does not have waste heat recovery power generation equipment suitable for low-temperature low-pressure steam, and the waste heat recovery power generation equipment suitable for low-temperature low-pressure steam needs to be provided for use.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the utility model provides a fast-assembling ORC generator set for recovering steam waste heat in hazardous waste industries, which comprises a container 1, wherein the container 1 is connected with a waste heat boiler 8 through a pipeline, the container 1 comprises an expander 2, a primary heat exchanger 3, a refrigerant pump 4, a secondary heat exchanger 5, a generator 6 and an air cooler 7, the expander 2, the primary heat exchanger 3, the refrigerant pump 4, the secondary heat exchanger 5, the generator 6 and the air cooler 7 are all installed in the container 1 and connected through a pipeline, the waste heat boiler 8 is connected with the primary heat exchanger 3 through a pipeline, the secondary heat exchanger 5 is connected with the primary heat exchanger 3, the refrigerant pump 4 is connected with the primary heat exchanger 3, the expander 2 is connected with the refrigerant pump 4, the generator 6 is connected with the expander 2, and the air cooler 7 is connected with the generator 6, the air cooler 7 is connected with the secondary heat exchanger 5.
The refrigerant pump 4 provides power for closed circulation of the refrigerant, the finally heated refrigerant at about 150 ℃ is pushed to enter the expander 2 for power generation, the refrigerant enters the air cooler 7 for cooling after power generation through the expander 2, and then enters the heat exchanger again for heating.
Specifically, the secondary heat exchanger 5 is provided with a return pipeline 9 for returning to the original process line.
Specifically, the expander 2, the primary heat exchanger 3, the refrigerant pump 4, the secondary heat exchanger 5, the generator 6 and the air cooler 7 form a closed circulation line inside the container 1. The refrigerant can be circulated in the closed circulation line.
The working principle of the utility model is as follows: when the system is used, a production device for burning hazardous wastes is connected with the fast-assembly ORC generator 6 group through a steam pipeline, low-temperature low-pressure steam at the temperature of about 150-200 ℃ is utilized to perform primary heat exchange with a refrigerant in the fast-assembly ORC generator 6 group, the refrigerant is heated to the temperature of about 150 ℃ through the heat exchanger by utilizing the heat in the steam, the steam after heat exchange through the primary heat exchanger 3 enters the secondary heat exchanger 5 through the pipeline inside the container 1 to perform secondary heat exchange with the refrigerant, the refrigerant is heated to the temperature of about 90 ℃, the refrigerant firstly passes through the secondary heat exchanger 5 and then passes through the primary heat exchanger 3; the low-temperature low-pressure steam passing through the secondary heat exchanger 5 is condensed into water at about 60 ℃, and because the steam pressure at the front end of the process line is greater than the condensed water pressure at the rear end, the condensed water of the low-temperature low-pressure steam takes the pressure difference as power and enters a subsequent process pipeline through a return pipeline 9.
After being heated to 90 ℃ for the first time, the refrigerant enters the primary heat exchanger 3 to be heated to 150 ℃, and then the refrigerant passes through the expander 2 to output power generation power which can reach 110 kW.
