Problems solved by technology

[0003] The current honeycomb activated carbon mainly has the following problems in the production process: the viscosity of the coal slime in the production process of the honeycomb activated carbon is difficult to make the activated carbon gather and press, which affects the production quality of the activated carbon, and the viscosity of the activated carbon causes the slime Adhered to the outer wall of the stirring plate, affecting the turning effect of the stirring plate; and in the process of punching the honeycomb activated carbon, the hole size is uneven, and the activated carbon is difficult to detach from the tapered needle

Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific drawings. It should be noted that, in the case of no conflict, the embodiments and Features in the embodiments can be combined with each other.

[0032] like Figure 1 to Figure 6 Shown, a kind of honeycomb activated carbon production and processing method, concrete honeycomb activated carbon production and processing method is as follows:

[0033] S1. Coal powder configuration: Brown coal or bituminous coal and coking coal are respectively crushed to ≤2mm, then mixed according to the mass ratio of lignite or bituminous coal:coking coal=1:0.2-0.5, and then ground to below 74 μm to obtain uniformly mixed coal powder;

[0034] S2. Emulsified coal tar: first step, high temperature coal tar with pitch content ≥ 55% is preheated to 120-150°C; second step, preparati...

Abstract

The invention provides a honeycomb activated carbon production and processing method. A bottom plate, a limiting support plate, a material guide plate, a material collecting unit, an auxiliary unit, an execution unit and a drying unit are matched to complete production and processing of honeycomb activated carbon. The problems that in the existing honeycomb activated carbon production process, activated carbon is difficult to gather, press and form due to viscosity of coal slime in the honeycomb activated carbon production process, the production quality of the activated carbon is affected, the coal slime adheres to the outer wall of a stirring plate due to viscosity of the activated carbon, and the activated carbon cannot be recycled, the overturning effect of the stirring plate is influenced, in the honeycomb activated carbon punching process, the hole size is not uniform, and the activated carbon is difficult to separate from a conical needle are solved.

Description

technical field [0001] The invention relates to the technical field of activated carbon processing, in particular to a method for producing and processing honeycomb activated carbon. Background technique [0002] Honeycomb activated carbon is a new type of environmentally friendly activated carbon exhaust gas purification product, which can effectively reduce odor and pollutants, and meet the national first-level exhaust gas emission standard. At present, there are high-grade coal-based activated carbon powder, high-iodine value coconut shell activated carbon powder, and super decolorized wood-based activated carbon powder in the domestic market, most of which are made of high-grade coal-based activated carbon powder into honeycomb-shaped activated carbon. [0003] The current honeycomb activated carbon mainly has the following problems in the production process: the viscosity of the coal slime in the production process of the honeycomb activated carbon is difficult to make ...
