Disclosure of Invention
The technical problem to be solved by the invention is to provide a multi-stage heat exchange device which can effectively utilize heat loss generated in the exhaust gas heating process while improving the heating effect and the energy consumption condition in the exhaust gas treatment heating process.
In order to solve the technical problems, the invention relates to a multi-stage heat exchange device based on waste heat utilization treatment, which comprises a heat exchange body; the heat exchange machine body comprises an air inlet port and an air outlet port, and a first heat exchange chamber, a second heat exchange chamber and a third heat exchange chamber are arranged in the heat exchange machine body, wherein the first heat exchange chamber and the second heat exchange chamber are communicated with each other, and the second heat exchange chamber and the third heat exchange chamber are communicated with each other; the air inlet port is connected with a heat exchange pipeline communicated to the inside of the heat exchange machine body, the heat exchange pipeline sequentially passes through the first heat exchange chamber and the second heat exchange chamber and is communicated to a third heat exchange chamber, and an electric heat source is arranged in the third heat exchange chamber; the air outlet port is communicated into the first heat exchange chamber.
As an improvement of the invention, among the heat exchange machine bodies, the first heat exchange chamber, the second heat exchange chamber and the third heat exchange chamber are sequentially distributed in the vertical direction; the heat exchange pipe extends in a vertical direction. By adopting the technical scheme, the heat exchange chambers can be arranged in the structure of a plurality of heat exchange chambers distributed in sequence in the vertical direction, so that the structure layout of the heat exchange chambers in the heat exchange machine is more compact, and the transmission efficiency of gas in the multistage heat exchange process is improved; meanwhile, the transmission path of the gas when the gas is conducted between any two heat exchange chambers in the heat exchange chambers adopting the structural layout accords with the natural motion direction of the gas, so that the transmission efficiency and effect of the gas in the heat exchange equipment can be further improved.
As an improvement of the invention, in the first heat exchange chamber, the part of the heat exchange pipeline in the first heat exchange chamber is positioned between the conduction position of the first heat exchange chamber and the second heat exchange chamber and the air outlet port; and among the second heat exchange chambers, the part of the heat exchange pipeline in the second heat exchange chamber is positioned between the conduction positions of the first heat exchange chamber and the second heat exchange chamber and between the conduction positions of the second heat exchange chamber and the third heat exchange chamber. By adopting the technical scheme, the gas which is heated by the electric heat source in the third heat exchange chamber sequentially passes through the second heat exchange chamber and the first heat exchange chamber until the gas outlet port, and uniform contact can be formed between the first heat exchange chamber and the second heat exchange chamber and between the first heat exchange chamber and the heat exchange pipeline respectively, so that the effect of auxiliary heat exchange treatment of the gas in the heat exchange pipeline is ensured.
As an improvement of the invention, in the third heat exchange chamber, the electric heat source extends to a position right below the end part of the heat exchange pipeline in the third heat exchange chamber. By adopting the technical scheme, the gas output from the heat exchange pipeline can be subjected to efficient and stable electric heating treatment.
As an improvement of the invention, the conducting position of the second heat exchange chamber and the third heat exchange chamber is provided with a catalyst layer. By adopting the technical scheme, the arrangement of the catalyst layer can be used for carrying out adsorption, neutralization and other treatments on harmful components in the gas when the gas passes through the conduction position of the adjacent heat exchange chamber, so that the heat exchange equipment in the application can carry out effective heating treatment on the gas and can also finish the purification treatment on the gas, thereby improving the overall efficiency of waste gas treatment.
As an improvement of the invention, a conduction chamber is arranged in the heat exchange machine body and positioned at the side end parts of the first heat exchange chamber, the second heat exchange chamber and the third heat exchange chamber, and the second heat exchange chamber and the third heat exchange chamber are conducted mutually through the conduction chamber; the end part of the first heat exchange chamber at one side of the conduction chamber is provided with a flow guide end plate, and the flow guide end plate extends downwards from the upper end part of the flow guide end plate towards the inside of the second heat exchange chamber in an inclined way; among the second heat exchange chambers, the end face of the catalyst layer at the position communicated with the third heat exchange chamber extends upwards from the lower end part of the end face towards the second heat exchange chamber in an inclined way.

In the process of conveying the waste gas in the second heat exchange chamber and the first heat exchange chamber, the waste gas can form high-temperature gas compared with the waste gas in the conveying stage in the heat exchange pipeline because the waste gas has higher temperature under the heating action of the electric heating source, so that auxiliary heating treatment can be formed on the waste gas in the heat exchange pipeline through contact with the heat exchange pipeline in the process of conveying the waste gas in the second heat exchange chamber and the first heat exchange chamber; the heating temperature of the gas in the second heat exchange chamber for the gas in the heat exchange pipeline is 200-350 ℃ and the heating temperature of the gas in the first heat exchange chamber for the gas in the heat exchange pipeline is 80-200 ℃ under the influence of the natural loss of the heat of the gas in the transmission process.
