Abstract
The invention discloses a combustion treatment method for carbonyl nickel-containing waste gas and relates to improvement of a combustion treatment method for the carbonyl nickel-containing waste gas generated in the carbonyl metallurgical production process. The method is characterized in that: by utilizing the Venturi principle of fluid for the combustion treatment of the carbonyl nickel-containing waste gas, a sleeve is arranged on an air inlet pipe of an incinerator; and a compressed air inlet pipe is arranged at the front end of the sleeve; therefore, the temperature of an exhaust pipe is reduced, and the distribution of the waste gas and air is realized. The method comprises the following steps of: opening a compressed air valve to introduce air into the sleeve, and opening a carbonyl nickel-containing waste gas inlet valve to perform mixed flow distribution combustion. By utilizing the Venturi principle of fluid, mixed flow distribution is performed before the waste gas is combusted, a negative pressure area is formed at the waste gas inlet, the rate for decomposing the carbonyl nickel in the waste gas at the air inlet to form nickel plating is delayed and the continuous treatment time of the waste gas is prolonged; therefore, the process of combusting the waste gas is continuously and stably performed, and the aim of timely disinfection is fulfilled.
Description
Technical field
A kind of burn processing method that contains carbonyl nickel waste gas relates to the improvement of the burn processing method that contains carbonyl nickel waste gas that produces in a kind of carbonylation metallurgical production process.
Background technology
In carbonylation metallurgical production process, can produce the waste gas that contains a small amount of carbonyl compound, these waste gas must could outer be discharged in the atmosphere after the disinfection.At present, in carbonylation metallurgical production process, be to adopt waste gas is input to carry out burning disposal in the incinerator; In burning process; Carbonyl nickel in the waste gas can decompose at the incinerator air inlet, forms nickel plating, gradually air inlet is stopped up; The burned waste gas process can not normally be carried out, hinder the normal tissues of production process to carry out.
Summary of the invention
The object of the invention is exactly the deficiency that exists to above-mentioned prior art; Provide a kind of and can solve incinerator air inlet nickel plating blockage problem in the burning process effectively; Make the burned waste gas process continuously, carry out for a long time; The waste gas disinfection that will produce in time will producing ensures that production process contains the burn processing method of carbonyl nickel waste gas normally.
The objective of the invention is to realize through following technical scheme.
A kind of burn processing method that contains carbonyl nickel waste gas; Its burn processing process adopts and will contain carbonyl nickel waste gas and feed the mode that incinerator burns and carry out; The carbonyl nickel waste gas that contains that it is characterized in that burn processing is the venturi principle that utilizes fluid, on the incinerator air inlet pipe, increases sleeve pipe, is provided with compressed air inlet pipe at the sleeve pipe front end; Both realize cooling exhaust pipe temperature, realized waste gas and air distribution again; At first open the compressed air valve and in sleeve pipe, blast earlier air, open again and contain carbonyl nickel waste gas air intake valve, carry out mixed flow distribution burning.
A kind of burn processing method that contains carbonyl nickel waste gas of the present invention is characterized in that the port of export that on the incinerator air inlet pipe, increases sleeve pipe exceeds incinerator air inlet pipe pipe port of export length 8～20cm.
