Problems solved by technology

In the prior art, the additives used are generally nanoscale Fe 2 S 3 Catalyst, this nanoscale Fe 2 S 3 When used as a coal-fired additive for gasifiers, it needs to be dissolved in water and sprayed on the coal. The addition method is cumbersome and the energy-saving effect is not obvious.
There are two reasons for the analysis: first, the coal sprayed with the catalyst does not directly enter the furnace cavity for combustion in the coal storage device in the furnace, and loses water while waiting in the coal storage device to enter the furnace cavity, causing the catalyst to perform poorly
Second, there is no cooling function, and the gasification time of coal in the furnace cannot be extended
It is difficult to reflect the energy saving effect

Embodiment Construction

[0020] The composition of the additive is: 10-20% of calcium hydroxide, 5-10% of sodium chloride, 55-65% of magnesium carbonate, 10-20% of calcium oxide, and the unit is percent by weight.

[0021] Additives are produced as follows:

[0022] 1. CaO coarse material is crushed and processed into 200 mesh production materials;

[0023] 2. CaO is moderately hydrolyzed to generate CaO and Ca(OH) 2 Production material A;

[0024] 3. MgCO 3 Coarse material is crushed into 200 mesh production material B;

[0025] 4. NaCl coarse material is crushed and processed into 100 mesh production material C;

[0026] 5. Put the three kinds of production materials A, B, and C into the mixer according to the weight ratio, and stir evenly, generally it can be stirred for 30 minutes; the amount of various materials added is: calcium hydroxide 10-20%, sodium chloride 5-10%, magnesium carbonate 55-65%, calcium oxide 10-20%;

[0027] 6. Put it into a packaging bag and sew it; stack it after 12 ho...

Abstract

The invention relates to gas producer special additive and its manufacturing method, and coal gas generation technique. The additive contains 10-20% calcium hydroxide, 5-10% sodium chloride, 55-65% magnesium carbonate, and 10-20% calcium oxide. The method is as follows: smashing the calcium oxide coarse material into 200 screen mesh; hydrolyzing it to form calcium oxide and calcium hydroxide; smashing the magnesium carbonate coarse material into 200 screen mesh; smashing the sodium chloride coarse material into 100 screen mesh; mixing them according to the additive contents. This additive can effectively reduce harmful substance in the smoke and prevent cinder from coking.

Description

technical field [0001] The invention relates to gas generation technology, in particular to an additive used in a gas generator. Background technique [0002] In the gasifier, in order to reduce the generation of pollutants and increase the gas production rate, it is usually necessary to add a catalyst-like substance to the coal. In the prior art, the additives used are generally nanoscale Fe 2 S 3 Catalyst, this nanoscale Fe 2 S 3 When used as a coal-burning additive for gasifiers, it needs to be dissolved in water and sprayed on the coal. The addition method is cumbersome and the energy-saving effect is not obvious. There are two reasons for the analysis: first, the coal sprayed with the catalyst does not directly enter the furnace cavity for combustion in the coal storage device in the furnace, and loses water while waiting in the coal storage device to enter the furnace cavity, resulting in poor performance of the catalyst. Its two, do not have cooling function, can...
