Problems solved by technology

However, the composition of organic waste gas is complex, flammable and explosive, and there are safety risks such as corrosion and explosion to the boiler. Exhaust gas with high moisture content will affect the efficiency of the boiler, and unstable air volume will affect the normal operation of the boiler.

Embodiment 1

[0063] 60000m3 / h of organic waste gas from a medical and chemical enterprise first enters the alkali washing absorption device for pretreatment, and then passes through the demister, exhaust gas induced draft fan, emergency discharge controller, air volume balance compensator, and then enters the boiler for incineration treatment through the boiler fan. The exhaust gas enters the desulfurization and dust removal device for desulfurization and dust removal. The exhaust gas composition of this project is complex. After thermal incineration in the boiler, the purification efficiency of non-methane total hydrocarbons is >96%. The specific data of import and export are shown in Table 1.

[0066] The composition of the organic waste gas of this project is complex, and the waste gas contains halogenated hydrocarbons such as dichloromethane. If the combustion conditions are not well controlled, secondary pollu...

Embodiment 2

[0070] The organic waste gas of a chemical company has a design air volume of 24500m3 / h. It first enters the adsorption or absorption device for pretreatment, and then enters three 130t / h fluidized bed coal-fired boilers through the boiler secondary fan for incineration treatment. The exhaust gas after it comes out enters the desulfurization process. The dust removal device performs desulfurization and dust removal treatment, and the total air volume of the flue gas is about 3000000m3 / h. It has been in operation for five years, and the thermal efficiency loss before and after waste gas incineration is about 1%. The boiler preheater is replaced once in the fourth year. The normal life of this type of boiler preheater is about 7 years.

[0071] Another medical and chemical enterprise’s organic waste gas has a designed air volume of 50,000m3 / h. Using the device of the present invention, it first enters the alkali washing absorption device for pretreatment, and then passes through ...

Abstract

The invention discloses a treatment system and a treatment process for organic waste gas boiler thermal incinerating. The treatment device comprises an absorbing device, a boiler fan, a boiler, a desulfurization, denitrification and dust removal device and a chimney which are sequentially connected, wherein a defroster, a waste gas draught fan, an emergency discharge controller and an air quantity balance compensator are arranged between the absorbing device and the boiler fan and are sequentially connected, the defroster is connected with the absorbing device, and the air quantity balance controller is connected with the boiler fan. The process has the advantage that on the premise of ensuring the purifying efficiency, by additionally arranging the defrosting treatment, the emergency discharge treatment and the air quantity balance treatment, the stability and safety of the whole treatment process are improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an organic waste gas boiler thermal incineration treatment system and a treatment process. Background technique [0002] Organic waste gas will cause serious harm to the environment and human beings, and has become one of the priorities of my country's environmental protection work. Efficient and simple organic waste gas treatment methods have attracted more and more attention. At present, the common methods of treating organic waste gas at home and abroad include adsorption method, absorption method, oxidation method, biological treatment method, etc. In recent years, some new technologies have emerged, such as membrane separation method, photolysis method and adsorption catalytic oxidation technology processing technology. The removal efficiency of organic waste gas by incineration is generally higher than that of absorption and adsorption methods, and it is gradu...
