Abstract

The utility model discloses a coil type waste heat utilization device of a smoke tube of a thermal treatment furnace. A coil (3) is arranged in a box (2); a water inlet of the coil (3) is communicated with a water inlet (2-1) of the box 2, and a water outlet of the coil (3) is communicated with a water outlet 2-2 of the box (2); the box (2) is arranged on an A smoke tube (4); a smoke inlet of the box (2) is communicated with a smoke outlet of the A smoke tube (4); a B smoke tube (5) is arranged on the box 2; and a smoke inlet of the B smoke tube (5) is communicated with a smoke outlet. The coil type waste heat utilization device has the advantages of heating water in the coil by using smoke temperature in the smoke tube, using heated water as domestic water, heating water by using waste heat of discharged smoke and saving precious energy.

Description

A kind of heat-treatment furnace chimney coiled residual heat using device

Technical field

The utility model relates to the heat-treatment furnace field, relates in particular to a kind of heat-treatment furnace chimney residual heat using device.

Background technology

At present, existing heat-treatment furnace is as main basically take gaseous fuel, when heat-treatment furnace in when work, can produce a large amount of flue gases in the body of heater, and flue gas can be discharged in chimney, because flue-gas temperature is higher, the words of directly discharging can be wasted a large amount of heat energy, can the smoke heat energy in the chimney not recycled and also install at present.

The utility model content

The purpose of this utility model is exactly also to install the deficiency that can recycle the smoke heat energy in the chimney for present, and a kind of heat-treatment furnace chimney residual heat using device is provided.

The utility model is comprised of casing, coil pipe, A chimney and B chimney, the casing top has into mouth, the bottom has outlet flue, the casing left side has water inlet, the right side has delivery port, water intaking valve is installed on the water inlet, outlet valve is installed on the delivery port, coil pipe is installed in the casing, and the water inlet of coil pipe communicates with the water inlet of casing, coil pipe delivery port communicate with the delivery port of casing, casing is installed on the A chimney, the mouth that advances of casing communicates with the outlet flue of A chimney, and the B chimney is installed on the casing, and the mouth that advances of B chimney communicates with the outlet flue of casing.

The utility model has the advantages that: the utility model can utilize the flue-gas temperature in the chimney that the water in the coil pipe is heated, and the water after the heating can be used as domestic water, utilizes smoke discharging residual heat that water is heated, and has saved and has protected the expensive energy.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, the utility model is by casing 2, coil pipe 3, A chimney 4 and B chimney 5 form, casing 2 tops have into mouth, the bottom has outlet flue, casing 2 left sides have water inlet 2-1, the right side has delivery port 2-2, water intaking valve 2-3 is installed on the water inlet 2-1, outlet valve 2-4 is installed on the delivery port 2-2, coil pipe 3 is installed in the casing 2, the water inlet of coil pipe 3 communicates with the water inlet 2-1 of casing 2, coil pipe 3 delivery port communicate with the delivery port 2-2 of casing 2, casing 2 is installed on the A chimney 4, the mouth that advances of casing 2 communicates with the outlet flue of A chimney 4, B chimney 5 is installed on the casing 2, and the mouth that advances of B chimney 5 communicates with the outlet flue of casing 2.

Working method: when flue gas is discharged in the chimney, add entry in the coil pipe 3 in the casing 2, the heat energy that coil pipe 3 absorbs in the flue gases, and the water in the coil pipe 3 are heated, then water flows out in delivery port 2-2, can use.
