Abstract
The invention relates to a quench device for suddenly cooling a hot gas stream with the aid of quench water. The inventive quench device comprises a gas supply line and a gas drainage pipe. Said quench water is at least partially cooled by means of a heat exchanger. In addition, said quench device is provided with a cooling water circuit for cooling the first area of the gas stream and with a second separate cooling circuit which cools a second area of the gas stream and is arranged downstream.
Description
Technical field
Equipment according to claim 1 and method according to claim 9 the present invention relates to the quenching to high-temperature gas.In addition, according to claim 15, the present invention relates to the use in the high temperature circulation process according to equipment of the present invention and the method according to this invention.
Background technology
In the extensive application of high-temperature technology technology, waste gas is cooled rapidly by adding the liquid such as water.This is called " quenching " process; The equipment that is used for this process is called " quenching equipment ".
Water circulates by means of the quenching pump.Between water inlet and delivery port, quenching water has heated about 10 to 30 ℃.This heat energy distributes from system by means of the quenching heat exchanger.
Described process is characterised in that: except refrigerating gas, the impurity that is arranged in gas also is deposited in liquid.To pollute the device of heat exchanger, pipeline and all carrying quenching water inevitably.Therefore must clean repeatedly.
Summary of the invention
The objective of the invention is to propose a kind of equipment and a kind of method, wherein, at first gas is cooled very effectively, and secondly cleaning can reduce to minimum.In addition, the objective of the invention is to propose the usage of a kind of like this equipment and such a kind of method.
The usage of the described equipment of claim 1, the described method of claim 9 and claim 15 has realized this purpose of the present invention.
The specific embodiment
Therefore, the present invention is to have proposed the such improvement of two stage quenching processes for the solution of the quenching problem of high-temperature gas.In two stages or zone of high temperature gas flow, cooling is to be undertaken by two cooling circuits that separate, and these two stages or zone are along flow direction continuous distributed of high-temperature gas.Therefore, quenching water circulates in two loops that separate.
Loop 1 is used for carry out actual quenching along the high-temperature gas in the first area of gas flow direction, and the solid particle that is included in the gas also precipitates herein; Loop 2 is used for the high-temperature gas along the second area of gas flow direction is cooled to final temperature at last.
According to the present invention, the usage of a kind of like this equipment or correlation method is provided, be used for cooling off the forming gas that occurs in the high temperature circulation process.
The invention has the beneficial effects as follows: solid particle is located, is deposited in the finite region of cooling by quenching.In conjunction with embodiment described below, can avoid of the pollution of precipitated solid particle fully to heat exchanger.
The quenching heat exchanger preferably only is arranged in the scavenger circuit 2.The energy that is included in the high-temperature gas dissipates by means of these quenching heat exchangers.Therefore, loop 1, i.e. Shi Ji quenching loop, being implemented as does not have heat exchanger.Therefore got rid of pollution basically to first cooling circuit.
Preferably a kind of elongate device of quenching equipment, it has an interior pipe that is provided with one heart, pipe and flow through described quenching equipment from the top to the bottom in hot gas enters from the top.In lower area, gas under the effect of a transfer and turn to, the outside annular gap and leave described quenching equipment in the upper end of upwards flowing through afterwards.In interior pipe, preferably be cooled to 95 ℃～70 ℃ from 1000 ℃～2000 ℃, especially be preferably 85 ℃, and be cooled to 70 ℃～40 ℃ from 85 ℃ in the annular gap externally, be preferably 60 ℃.
In the preferred variants of described equipment, quenching water is discharged by freely overflowing to the loop 1 from loop 2.
In a further advantageous embodiment, the water level of the quenching water in loop 1 and loop 2 is by the water level control of the quenching water in the loop 1.The device that is used for regulating water level is preferably by providing water or 1 discharge water realizes from the loop to loop 1.
In the method according to the invention, preferably to being in 1000 ℃ to 2000 ℃, the waste gas that is preferably 1200 ℃ carries out quenching.In the first area that preferably includes pipe in, quenching makes high-temperature gas drop to 95 ℃～70 ℃ from being higher than 1200 ℃, is preferably 85 ℃.
Described method is applicable to that preferably the percent by volume of water content is 10% to 70%, and preferably percent by volume is 30% waste gas.
