The direct-heating tube-type heat recovery to supply hot water to employee bathhouse

This system uses the Structure of 3D inner catheter and has advantages of zero Pressure loss during the Heat Recovery, not easy to scaling and Leakage,low fault rate and long lifespan, ect.

Because of the reasonable design of air compressor room and Pipe Routing as well as the energy-efficient and Power-saving set of water pump, there is no problem during the using and operation.

It avoids the problems, easy puncture leakages, scaling and the unstable hot water supply of plate heat exchanger.

1. The Present situation of hot water supply in market

Many companies use gas fired boiler to heat the water to supply the bathhouse for employee's baths.

We find the following problems after the analysis of factory energy saving.

(1)The gas fired boilers are working to full capacity, every year, the expense of the gas is more than 700,000 Yuan.

(2)In the way, they have to open the hot water supply at regular time, while the hot water for the employee bathhouse is not stable.

The temperature of composer is more than 100℃, which leads to closing every 2-3 hours and has a crippling effect on working efficiency.

2. The analysis of feasibility

After the analysis of on-site field investigation, our engineers think if the composer can be modified more energy-efficient, it could not only saves the problem about the high temperature of the composer operation, but also replace the gas fired boiler to supply hot water.

Our system can protects the service life of composer and the stability of hot water supply from two aspects, meanwhile minimizes the maintenance cost.

3. Benefits of Energy Saving

(1)Many companies choose the direct-heating tube-type heat exchanger, recovers the heat of the compressed air and lubricating oil.

(2)The direct-heating tube-type heat exchanger has a high efficiency of heat recovery, the recovery efficiency is up to 80%, the temperature of composer operation reduces almost a dozen degree Celsius.

(3)And it prolong the service life of  lubricating oil and make the hot water temperature up to 65℃ to applies the water for life of employee.

 (4)Therefore, it solves the high temperature of composer operation to ensure the normal running.

(5)After reforming the system by using the direct-heating tube-type heat exchanger, which replaces the gas fired boiler with advantages of stable and unlimited hot water supply, you can saves the cost that exceeds 700,000 Yuan every year, and creates good economic benefits for itself.
