Problems solved by technology

The temperature of the fresh air used in actual production is basically the same as the outside air temperature, and it will absorb a lot of heat to make the whole system reach thermal balance; while the heat of the flue gas taken away by environmental protection facilities such as dust collectors in the production system is scattered into the air Cause heat loss. In this case, in order to ensure the output, the fuel consumption can only be increased, which increases the production cost and causes a great waste of resources.
Moreover, the traditional heat exchanger is generally welded by the shell, the partition, and the connecting pipe. The fresh air goes straight in and out, the air flow is unevenly distributed and the flow velocity is fast, which greatly reduces the heat exchange rate. , can only increase the connecting pipe of the heat exchanger, which will increase the volume of the heat exchange port and occupy a large space, thus increasing the investment cost

Abstract

The invention relates to a waste heat recovery heat exchange device of belt type updraft sintering machine which includes a heat exchange case, an right upper part of the heat exchange case is equipped with a waste heat inlet, a left upper part of the heat exchanger case is equipped with a waste heat outlet, a down part of the heat exchanger case is equipped with a collect dust bucket, a middle part of the heat exchanger case is equipped with a middle gas chamber, a right side of the heat exchanger case is equipped with a fresh air inlet, a left side of the heat exchanger is equipped with a fresh air outlet; two sides of the middle gas chamber are equipped with some exchanging gas chambers symmetrically; an air inlet clapboard is welded on the fresh air inlet, the air inlet clapboard connects with an exchange gas chamber on right side of the heat exchanger case inner through certain connecting pipes. The waste heat recovery heat exchange device has advantages of increasing maneuverability of each post in manufacturing system, reducing coal consumption amount 20-22%, reducing coking rate 1.5-2%, saving fuel consumption amount, reducing manufacturing cost and increasing manufacturing ability.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a waste heat recovery heat exchange device for a belt blast sintering machine. Background technique [0002] The traditional sintering-blast furnace production system uses the oxygen in the fresh air to oxidize the material and reduces it with coke to produce the product. The temperature of the fresh air used in actual production is basically the same as the outside air temperature, and it will absorb a lot of heat to make the whole system reach thermal balance; while the heat of the flue gas taken away by environmental protection facilities such as dust collectors in the production system is scattered into the air Heat loss is caused. In this case, in order to ensure the output, the fuel consumption can only be increased, which increases the production cost and causes a great waste of resources. Moreover, the traditional heat exchanger is generally welded by the shell, the partit...
