Abstract

PURPOSE:To make it possible to clean dusts easily by impinging a gas to be treated onto a heat accumulating material at the surface of an endless belt to attach dusts on its surface and at the same time spreading a heat carrier such as water on this heat accumulating material. CONSTITUTION:The air returning from the room passes as shown by the arrow through ducts 7-9 and carried to a heat exchanger that consists of a chain conveyor 1, and exchanges its heat with a heat accumulator 1A, and at the same time the dusts in it are attached onto the surfaces of the heat accumulator 1A to remove dusts. The air that has lost its dusts is supplied to the room. On the other and the temperature of the heat accumulating material 1A gets near the room temperature after the heat exchanging and the material 1A moves downwards and again acquires a temperature difference from the room temperature after passing through a water tank 3 and receiving cold water spray and at the same time the dusts on the surfaces are cleaned and removed. The above mentioned processes are repeated to effect heat exchanging with the dusts in the air removed.

Description

[Detailed description of the invention] This invention relates to a heat exchange device that performs both dust removal and temperature control.

Conventionally, dust removal and heat exchange equipment installed in ducts where gas flows have been equipped with autoroll filters and fin coil filters, which automatically exchange new furnace material and old slough material based on the pressure difference before and after the filter. Combinations of heat exchangers are known.

However, in such a configuration, even if an autoroll filter is used in a dusty area, the furnace material must be replaced every month or so, and since the furnace material is disposable, maintenance costs are high. Another drawback is that it requires a lot of space for installation.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the above-mentioned conventional techniques, and to provide a heat exchange device that can be used for both cleaning and cleaning, which facilitates the cleaning and regeneration of furnace materials, and which requires a small installation area.

The present invention provides an endless belt mounted on a pair of sprockets connected to a driving means so as to vertically cross a duct through which a gas to be treated flows, and a heat storage material provided on the surface of the endless belt. By colliding the gas to be treated with the heat storage material to cause dust to adhere to the heat storage material, and spraying a heat medium such as hot or cold water onto the heat storage material to which the dust has adhered, heat is stored in the heat storage material and at the same time the dust is deposited on the surface of the heat storage material. It is designed to clean the dust that has been removed.

Hereinafter, the present invention will be explained in more detail with reference to the drawings. 1st
The figure is a sectional view of a heat exchange device showing an embodiment of the present invention. This device has a duct for the gas to be treated, that is, the first floor.
2nd and 3rd floor return air ducts 4.5 and 6, and 1
A pair of return air ducts 7, 8 and 9 are installed vertically across the return air ducts 7, 8 and 9 on the second and third floors. material IA, and sprockets 2A and 2B that support the upper and lower ends of the chain conveyor and are interlocked with a drive device.
and a water tank 3 arranged so that the lower end of the chain conveyor is immersed in water, and the water in the water tank is pumped through a pump 16, a valve 2o or 21, a refrigerator 17 or a boiler 18, and a valve 20. 21° and line] 9 to make cold or hot water, which is then passed through line 19 and spray nozzle 13.
It mainly consists of a water spraying mechanism that sprays water onto the heat storage material IA on the chain conveyor 1 to cool or heat it.

The surface of the heat storage material IA is provided with irregularities so that dust can easily adhere thereto. The water tank 3 includes a water filter 14 and a pump 1.
A water purification system consisting of 5 parts is attached. Air blowers 10, 11 and 12 are provided on the air supply side in each duct. The pulp 20 of the refrigerator 17 of the water dispersion mechanism is adjusted to be open in the summer and closed in the winter, and the pulp 21 of the boiler 18 is adjusted to be closed in the summer and open in the winter.

In the above configuration, the return air from the room is carried through the duct as shown by the arrow to the heat exchange section consisting of the chain conveyor 1, where it exchanges heat with the heat storage material IA and at the same time removes dust from the surface of the heat storage material IA. After being removed, air is supplied to the room. On the other hand, the heat storage material IA approaches room temperature after heat exchange,
After moving toward the bottom and passing through the water in the aquarium, it is sprayed with hot or cold water to obtain a temperature difference from room temperature again, and at the same time, the dust on the surface is washed and removed. The above operations are repeated to exchange heat and remove dust from the air.

In the above embodiment, the belt 1 may be any other type of belt as long as it can add more heat storage material IA. The heat storage material IA may be made of any material, such as synthetic resin, as long as it has a relatively large heat capacity and has a heat exchange function.

As described above, according to the present invention, the dust attached to the surface of the heat storage material is automatically cleaned even when it is carried out in a dusty place, so there is no need for a lot of maintenance cost, and the installation space is also limited to the inside of the duct. Since only the part of the heat storage material that passes through is required, it can be made small, making it possible to provide an extremely efficient dust removal and heat exchange device.
