Abstract

The utility model relates to a gas ascending pipe residual heat recovering device for a coke furnace. The utility model can reduce energy consumption and can improve working environment. The utility model belongs to the technical field of environmental protection and energy saving. The utility model is composed of a gas ascending pipe. The utility model can the solving technical proposal that the utility model is composed of a jacketing outer casing, a jacketing inner casing, an upper sealing head, and a lower sealing head; the components are matched with backwater ports and outlets; the components are installed on the top of the coke furnace; the main body of the utility model presents the sleeve barrel shape, and the main body can be matched with a steam-water separator to work; soften water can enter a water jacket by the backwater port so as to be changed into steam water to flow into the steam-water separator by the water outlet; the produced steam can be outputted by the outlet. The utility model can use the form of the water jacket to recover residual heat, so that the temperature at a gas outlet can be reduced by more than 200DGE. Thus, the utility model not only can effectively improve workers' operational environment, but also can recover a great amount of heat energy. The utility model can create good economical and social benefits.

Description

A kind of coke-oven gas upcast waste-heat recoverer

The utility model relates to the environment protection energy-saving equipment technical field, particularly to the waste-heat recovery device of coke-oven gas.

Coke oven discharged producer gas temperature is 650-750 ℃, present gas up take mostly is steel plate Volume system, inner lining refractory, coal gas of high temperature is not only taken away a large amount of sensible heats in vain, and the appearance temperature is very abominable up to making operating system on every side become red-hot unbearable to three, 400 gas up takes of spending.

The utility model is to realize like this, a kind of coke-oven gas upcast waste-heat recoverer, constitute by gas up take, the key problem in technology of its solution is that main body is the cover tubular, cooperate steam separator, softening water enters water jacket by water return outlet and becomes steam water and flow into steam separator by water outlet, and the steam of generation is by outlet output.Gas up take is made a chuck of being made by Clad Steel, is full of soft water in the chuck, by water with the form of the latent heat of vaporization and sensible heat with waste heat recovery with compile, reach the purpose of waste heat recovery, to improve workman's operating environment.

The utility model adopts the form of water jacket to carry out waste heat recovery, can make gas outlet temperature descend more than 200 ℃, not only changed workman's operating environment effectively, and recyclable a large amount of steam, it is calculated that, the coke oven of 42 holes * 2, per hour recyclable steam 3.6T, a year benefit reaches more than 120 ten thousand yuan.

Be described in detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model front view (partly cuts open and add partial cutaway).

Fig. 2 is the utility model fundamental diagram.

In conjunction with Fig. 1,2, the utility model is the cover tubular, and is two-layer inside and outside dividing, and cooperates steam separator (11) work, softening water enters water jacket by water return outlet (4) and becomes steam water by water outlet (5) inflow steam separator (11), and the steam of generation is by outlet (12) output.

The coke-oven gas upcast comprises water jacket (3), is provided with spiral recirculated water guide vane (6) in the water jacket (3).

The utility model main body is made up of chuck shell (2), chuck inner casing and upper cover (1), lower cover (7), and be equipped with water return outlet (4), water outlet (5), be installed in and push up on (8) on the coke oven, for improving heat exchange efficiency and increasing inner casing rigidity, be welded with volution guide vane (6) at the inner casing outer wall.Hot water in the interlayer is by the manifold collection rising main (10) of water outlet (5), flow into steam separator (11), the make up water of each upcast is supplied with by return main (9), steam separates in steam separator (11), through vapour outlet (12) output (14) with (15) are respectively hydraulic ga(u)ge and blowdown is cut down, soft water is gone into by water-in (13) benefit.

Claims

1. coke-oven gas upcast waste-heat recoverer, constitute by gas up take, it is characterized in that main body is the cover tubular, cooperate steam separator (11), softening water enters water jacket (3) by water return outlet (4) and becomes steam water by water outlet (5) inflow steam separator (11), and the steam of generation is by outlet (12) output.

2. according to the described coke-oven gas upcast of claim 1 waste-heat recoverer, it is characterized in that the coke-oven gas upcast is made of water jacket (3).

3. according to claim 1 or 2 described coke-oven gas upcast waste-heat recoverers, it is characterized in that being provided with in the water jacket (3) spiral recirculated water guide vane (6).
