Abstract
The invention relates to a metallurgical furnace waste heat utilizing device which comprises a heat exchange box and a heat exchange tube nest vertically arranged in the heat exchange box. The heat exchange box is provided with an air inlet, an air outlet and a dust collecting opening in the bottom of the heat exchange box. A water inlet and a water outlet of the heat exchange tube nest are located at the top of the heat exchange box, and the heat exchange tube nest comprises a plurality of vertical tubes and bent tubes used for connecting the vertical tubes. A sealed water tank is arranged at the top of the heat exchange box, and the lower portion of the sealed water tank is communicated with the interior of the heat exchange box through a plurality of water nozzles. The upper portion of each vertical tube is at least provided with one water nozzle, and an air pump is arranged on the top of the sealed water tank. According to the metallurgical furnace waste heat utilizing device, water is supplied through the sealed water tank on the top of the heat exchange box, under the assistance of the air pump, the water in the sealed water tank is sprayed out from the water nozzles so as to flush away dust on the walls of the vertical tubes of the heat exchange tube nest, high heat exchange efficiency of the heat exchange tube nest can be continuously maintained, waste heat is fully recovered, and the economic value of a waste heat system is increased.
Description
Technical field
The present invention relates to energy saving technology in metallurgy field, particularly a kind of metallurgical furnace residual heat using device.
Background technology
The purifier of metallurgical furnace flue gas is metallurgical furnace flue gas generation equipment in the prior art, waste heat utilization facility, deduster connected successively by pipeline.Usually the waste heat utilization facility adopted at present is heat exchanger, is that one can reduce flue-gas temperature, high-temperature flue gas can be utilized again simultaneously, reach the equipment of heat exchange object.Water row tube waste heat boiler, heat storage type heat-pipe heat exchanger reclaim the waste heat of metallurgical furnace flue gas, produce saturated vapor etc.Due to the fluctuation of metallurgical furnace flue gas high temperature, dustiness is large, and light water tubulation waste heat boiler is difficult to the waste heat recovery applying to metallurgical furnace flue gas.Because metallurgical furnace flue gas dustiness is large, when using water row tube waste heat boiler, early stage, heat transfer effect was relatively good, along with the prolongation of service time, heat exchanging pipe wall can accumulate increasing flue dust, cause heat exchange efficiency to decline, relatively reduce the economic worth of residual heat system, add the investment of residual heat system.
Summary of the invention
The technical problem to be solved in the present invention is: large in order to solve existing metallurgical furnace flue gas dustiness, when using water row tube waste heat boiler, early stage, heat transfer effect was relatively good, along with the prolongation of service time, heat exchanging pipe wall can accumulate increasing flue dust, heat exchange efficiency is caused to decline, relatively reduce the economic worth of residual heat system, add the problem of the investment of residual heat system, the invention provides a kind of metallurgical furnace residual heat using device, supplied water by the sealing radiator at heat exchange box top, air pump auxiliary under, water in sealing radiator is sprayed from water spout, the flue dust of the VERTICAL TUBE tube wall of heat exchanging tubulation rinses, can continue to keep higher heat exchange efficiency, fully carry out waste heat recovery, improve the economic worth of residual heat system.
The technical solution adopted for the present invention to solve the technical problems is: a kind of metallurgical furnace residual heat using device, the heat exchanging pipe comprising heat exchange box and be vertically arranged in heat exchange box, heat exchange box has air inlet, air outlet and the dust collecting opening be arranged on bottom heat exchange box, the water inlet of heat exchanging pipe and delivery port are arranged on the top of heat exchange box, heat exchanging pipe comprises some VERTICAL TUBE and the bend pipe for vertical connecting pipe, described heat exchange box top is provided with a sealing radiator, described sealing radiator bottom is communicated with heat exchange box inside by some water spouts, described each VERTICAL TUBE top is at least provided with a water spout, described sealing radiator top is provided with an air pump.
As preferably, described each VERTICAL TUBE top is provided with a water spout.
The invention has the beneficial effects as follows: a kind of metallurgical furnace residual heat using device provided by the invention, supplied water by the sealing radiator at heat exchange box top, air pump auxiliary under, water in sealing radiator is sprayed from water spout, the flue dust of the VERTICAL TUBE tube wall of heat exchanging tubulation rinses, can continue to keep higher heat exchange efficiency, fully carry out waste heat recovery, improve the economic worth of residual heat system.

In figure: 1. heat exchange box, 2. heat exchanging pipe, 3. air inlet, 4. air outlet, 5. dust collecting opening, 6. water inlet, 7. delivery port, 8. VERTICAL TUBE, 9. bend pipe, 10. sealing radiator, 11. water spouts, 12. air pumps.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of metallurgical furnace residual heat using device, comprise heat exchange box 1 and be vertically arranged on the heat exchanging pipe 2 in heat exchange box 1, heat exchange box 1 has air inlet 3, air outlet 4 and the dust collecting opening 5 be arranged on bottom heat exchange box 1, the water inlet 6 of heat exchanging pipe 2 and delivery port 7 are arranged on the top of heat exchange box 1, heat exchanging pipe 2 comprises some VERTICAL TUBE 8 and the bend pipe 9 for vertical connecting pipe 8, heat exchange box 1 top is provided with a sealing radiator 10, sealing radiator 10 bottom is communicated with heat exchange box 1 inside by some water spouts 11, each VERTICAL TUBE 8 top is at least provided with a water spout 11, sealing radiator 10 top is provided with an air pump 12.
As preferably, each VERTICAL TUBE 8 top is provided with a water spout 11.
In use, only need open air pump 12 to air feed in sealing radiator 10, make water in water spout 11, spray to VERTICAL TUBE 8 under the effect of the pressure, thus the flue dust on VERTICAL TUBE 8 wall of heat exchanging pipe 2 is rinsed out, then from the flue dust collecting that dust collecting opening 5 will scrape, and focus on.
