The technical realization elements of the heater system at the entrance of the blast duct

Technical realization elements:

4. The purpose of the present utility model is to provide a blast duct inlet heater system to solve the problem of the existing industrial boiler waste heat recovery device during use of the existing blast duct proposed in the background art. It is complicated and the heat exchange effect is poor, so that the heat carried by the waste water cannot be used in time, and it is easy to cause the problem of heat waste.

5. In order to achieve the above objective, the present invention provides the following technical solutions: a blower inlet heater system, including a waste water storage device, one end of the waste water storage device is fixedly installed with a circulating pump, the circulating pump is far away from the waste water A heating device is fixedly installed at one end of the storage device. The interior of the waste water storage device includes a box body. The inner wall of the box body is fixedly connected with a support block. The top of the support block is provided with a ceramic filter plate. The outer wall of the box is fixedly connected with the top of the support block, and the inner wall of the box body is fixedly connected with an electric heating rod.

6. Preferably, one end of the box body is provided with a water inlet pipe, the outer wall of the water inlet pipe is fixedly connected with the inner wall of the box body, and the inner wall of the other end of the box body is fixedly installed with a water outlet pipe.

7. Preferably, the inside of the heating device includes an air inlet tube, the inner wall of the air inlet tube is fixedly installed with a metal protection net, and the inside of the metal protection net is provided with a connecting shaft, and the outer wall of the connecting shaft is connected to the metal The inner wall of the protection net is movably connected.

8. Preferably, one end of the connecting shaft is provided with a connecting ring, the inner wall of the connecting ring is fixedly connected with the outer wall of the connecting shaft, the outer wall of the connecting ring is fixedly installed with a flow regulating fan blade, and the outer wall of the connecting shaft A fixed frame is installed for the activity.

9. Preferably, one end of the air inlet tube is fixedly installed with a heating air tube, the bottom of the heating air tube is fixedly installed with a water inlet pipe, and one end of the water inlet tube is provided with a heat exchange coil, the heat exchange coil One end of the heat exchange coil is fixedly connected with one end of the water inlet pipe, and the other end of the heat exchange coil is fixedly connected with a drain pipe.

10. Preferably, the inner wall of the heating air cylinder is fixedly installed with an insulation layer, the heating air cylinder is provided with a dust-proof net, and the outer wall of the dust-proof net is fixedly connected to the inner wall of the heating air cylinder, and the heating A sealing ring is fixedly installed on the outer wall of the air cylinder.

11. Preferably, one end of the sealing ring is provided with a mounting plate, the inner wall of the mounting plate is fixedly connected to the outer wall of the heating air cylinder, and the end of the heating air cylinder away from the sealing ring is fixedly mounted with a connecting cylinder, the connection An auxiliary heater is fixedly installed on the inner wall of the cylinder.

12. Compared with the prior art, the beneficial effects of this utility model are:

13.1. Waste water can be treated and stored through the waste water storage device, which facilitates the collection and utilization of waste heat of waste water, timely utilizes the waste heat, reduces heat loss, and can prevent the residue in the waste water from clogging the pipeline, and when the waste water stays in the tank , The residue in the waste water is buffered and precipitated by the support block in the box, and the supernatant liquid is filtered through the ceramic filter plate before using the waste heat of the waste water.

14.2. The waste heat in the wastewater can be reused in time through the heating device. The gas can be heated through the heat exchange coil to realize the waste heat utilization of the waste water and increase the airflow temperature at the inlet of the blast duct. When wastewater is injected or the temperature of wastewater is low, the heating effect is ensured, and the temperature of the gas at the inlet of the blast duct is guaranteed.
