Abstract

The utility model relates to a recovery equipment for recycling waste heat in waste gas exhausted from large-size boilers, ceramic tunnel furnaces, glass melting furnaces, steel rolling hot-air ducts, exit flues of large-power diesel generators, etc. The utility model is characterized in that a smoke box and a heat tube are installed in an inclined way. The steam drum and the smoke box of the utility model are installed in an angle with a declination range from 10DEG to 70DEG with the horizontal line, which reduces accumulated dust, fully recycles waste heat and saves coal energy and funds. The utility model also has great social and economic benefits.

Description

Inclined heat tube waste heat furnace

The utility model is the equipment of recovery waste heat from institute's combustion gas such as large-sized boiler, ceramic tunnel kiln, glass melter, rail steel hot-flow flue, high-power diesel-driven generator smokejack.

Traditional heat pipe heat exchanging equipment by drum, smoke box, and smoke box in fin is installed heat pipe formed, the UNICOM of the heat pipe in the UNICOM between drum and the smoke box, the smoke box all adopts rectilinear installation, flue gas is parallel with heat pipe and mistake by drum during by smoke box, and fin is to be enclosed within install vertical with heat pipe on the heat pipe.Contain the intact soot particle of certain dust and unburned, mist of oil etc. in the useless flue gas.These dirts just drop on the vertically arranged fin of heat pipe on.Useless flue gas has certain temperature, so flue dust is bonded on the outer wall and fin of heat pipe, even frequent water deashing and since heat pipe be vertically be mounted to make on former heat extraction pipes and fin on flue dust can be washed out by water, and the dust that the heat pipe of back and pipe are gone up on the fin is difficult for washing out.In the course of time, always have the dead angle to accumulate flue dust on heat pipe and the fin, cause the exchange capability of heat of heat pipe to weaken, waste heat can not make full use of.So in original technology vertically arranged shortcoming be the flue dust that accumulates not water dust out, particularly heat pipe and the fin of easy-to-use usual pressure the flue dust dead angle has appearred, thereby reduced the exchange capability of heat of heat pipe, cause waste heat not make full use of.

In order to overcome the shortcoming in original technology, the purpose of this utility model is that smoke box is placed on drum one side, and the heat pipe in the smoke box becomes 10 degree～70 degree angles tilt to install with horizontal plane, flue gas by the time parallel with fin, be difficult for accumulating flue dust, add and adopt the giant flushing, thereby designed a kind of tilting heat pipe waste-heat oven equipment, reduced the laying dust phenomenon, increased waste heat recovery, improve the thermal efficiency, saved the energy, reduced cost.

The utility model is achieved through the following technical measures.

A kind of tilting heat pipe waste-heat oven, it is made up of the smoke box of drum and installation heat pipe, it is characterized in that:

Smoke box is installed in a side of drum, in the smoke box installation of heat pipe be with horizontal line under be poured on 10 the degree～70 degree scopes in, adopt giant, wash away with high-temperature water, because the heat pipe level is installed, the flue gas direction is parallel with the fin installation direction, so reduce laying dust, add and use high temperature, water under high pressure to wash away, just the flue dust dead angle can on fin, not occur.

Advantage of the present utility model:

(1) is difficult for falling ash on the angle change of installing, the fin, also is difficult for accumulating flue dust, thereby prolonged service time, improved the thermal efficiency owing to heat pipe.

(2) owing to adopt high temperature, water under high pressure and special-purpose hydraulic giant, be easy to wash away, guarantee the effect of waste heat recovery reaching flue dust, the adhesive of accumulating on the heat pipe on the fin.

(3) because the rate of recovery height of waste gas residual heat, thereby save the energy, reduced cost.

The A of Fig. 5, Fig. 4 is to view.

See Fig. 1, original technology scheme of installation, smoke box 3 are installed in below the drum 1, and heat pipe 5 is installed in the smoke box 3, and fin 4 and heat pipe 5 vertical installations accumulate the flue dust dead angle on the fin 4 on the heat pipe 5 in the smoke box in original technology.Laying dust on the back heat extraction pipe fin is difficult for washing away, and sees Fig. 3.

Fig. 4 is the utility model structural representation.

Smoke box 3 is installed in a side of drum, becomes in 10 degree～70 degree angular range with horizontal line when the heat pipe 5 in the smoke box 3 is installed.See A to view, flue gas 6 enters smoke box 3 from entering the mouth, and waste hot gas is transmitted to the heat pipe light section 2 in the drum 1 with heat pipe 5 and fin 4 heating, makes it waste gas like this by the heat pipe recovery waste heat, and waste gas is discharged from exporting 7.

Claims

A kind of tilting heat pipe waste-heat oven, it is made up of drum and smoke box that heat pipe, fin be installed, it is characterized in that smoke box is installed in a side of drum, and heat pipe is installed in to have a down dip with horizontal line and 10 spends in～70 degree scopes in the smoke box.
