Abstract

The invention relates to a sulfur melting waste gas recycling method. The sulfur melting waste gas recycling method comprises the following steps: after sulfur melting waste gas is twice absorbed by a venturi injector and an absorption tower, the waste gas reaches the standard and can be released; water absorbing the sulfur melting waste gas passes through a settlement pond I and stands still and settles in the settlement pond I, sulfur precipitates are press-filtered and recovered by a filter press, water after filter pressing is discharged to a settlement pond II and settles again, then the water reaches the standard and can be discharged. The method solves the problem of generation of waste gas and waste water in a sulfur melting process and can reduce the environment pollution, sulfur can be recycled after waste gas treatment, and the production cost is reduced.

Description

A kind of recovery method of molten sulphur waste gas
Technical field
The present invention relates to a kind of method of acid production with sulphur, particularly a kind of recovery method of molten sulphur waste gas.
Background technology
Take sulphur as the device of waste, be Molten sulphur is sprayed into sulfur furnace burning produce sulfur dioxide gas to produce sub-salt.If do raw material with solid sulfur, must be just Molten sulphur by its solid sulfur melting, this operating process be referred to as molten sulphur process.
Can produce a large amount of waste gas in molten sulphur process, the Main Ingredients and Appearance of waste gas is trickle sulfur granules, gaseous sulfur, hydrogen sulfide, sulfur dioxide and a large amount of steam.Molten sulphur waste gas is directly entered in air by chimney by current most of enterprise, very large pollution is caused to surrounding environment, working site smell is very unpleasant, also some enterprise with blower fan will melt sulphur tail gas suction one absorption tower water absorb after emptying again, but return a large amount of waste water of generation not easily to process, easily cause environmental pollution.
Summary of the invention
The object of this invention is to provide a kind of molten sulphur gas recovery method, molten sulphur waste gas is effectively reclaimed, thus alleviates the pollution to environment.
Technical scheme of the present invention is as follows:
A recovery method for molten sulphur waste gas, is characterized in that comprising the following steps:
After molten sulphur waste gas is collected by pipeline, first carry out injection through Wen's injector to absorb, send into absorption tower again, the water (from the water of cooling tower and the alkaline aqueous solution that supplemented by water circulating pump) being about 8 with PH absorbs again, emptying is drawn through air-introduced machine, qualified discharge by the waste gas after twice absorption.
The water after molten sulphur waste gas is absorbed in absorption tower, the water that tower bottom divides is drawn from bottom, and send into No. 1 settling tank, the water of top section is transported to cooling tower and cools, the water divided by tower bottom after cooling also sends into No. 1 settling tank, and the water water circulating pump of top section is squeezed into absorption tower and recycled; After waste water standing sedimentation in No. 1 settling tank, with filter press, sulphur precipitation is wherein carried out press filtration recovery, the water after press filtration is disposed to No. 2 settling tanks and again precipitates rear qualified discharge; The sulphur of filter press press filtration clears out and dries rear reuse.
The invention has the advantages that:
1. the invention solves in molten sulphur process and produce waste gas, useless water problem, decrease the pollution to environment.
2. can be recycled to sulphur after exhaust-gas treatment, reduce production cost.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Detailed description of the invention
As shown in Figure 1: be after 130 DEG C of molten sulphur waste gas are collected by pipeline by temperature, first carry out injection through Wen's injector to absorb, send into absorption tower again, the water (from the water of cooling tower and the aqueous sodium carbonate that supplemented by water circulating pump) being about 8 with PH absorbs again, reaches 0.35mg/m by the exhaust gas concentration after twice absorption 3below, emptying qualified discharge is drawn through air-introduced machine.
Absorb the water part water after superfusion sulphur waste gas in absorption tower to draw bottom absorption tower, sending into volume is 20 m 3no. 1 settling tank; A part is transported to cooling tower and cools to 30 ~ 40 DEG C, and the water divided by tower bottom after cooling also sends into No. 1 settling tank, and all the other recycle with water circulating pump absorption tower of hitting the person.After waste water standing sedimentation in No. 1 settling tank, through filter press, sulphur precipitation is wherein carried out press filtration recovery, the water after press filtration is disposed to 20 m 3no. 2 settling tanks again precipitate rear qualified discharge.The sulphur of filter press press filtration clears out and dries rear reuse.

Claims (1)

1. a recovery method for molten sulphur waste gas, is characterized in that comprising the following steps:
After molten sulphur waste gas is collected by pipeline, first carry out, after injection absorption, sending into absorption tower and again absorbing, draw emptying by the waste gas after twice absorption through air-introduced machine, qualified discharge through Wen's injector; The water after molten sulphur waste gas is absorbed in absorption tower, the water that tower bottom divides is drawn from bottom, and send into No. 1 settling tank, the water of top section is transported to cooling tower and cools, the water divided by tower bottom after cooling also sends into No. 1 settling tank, and the water water circulating pump of top section is squeezed into absorption tower and recycled; After waste water standing sedimentation in No. 1 settling tank, with filter press, sulphur precipitation is wherein carried out press filtration recovery, the water after press filtration is disposed to No. 2 settling tanks and again precipitates rear qualified discharge.
