Embodiment 1

[0031] Example 1: A method for making wallboard by utilizing sludge, the partition wallboard comprises the following components in parts by weight: 23 parts of dodecylbenzene sulfonic acid, 3 parts of sodium hydroxide, ethoxylated 8 parts of sodium alkyl sulfate, 5 parts of inorganic fibers, 20 parts of magnesia, 200 parts of cement, 500 parts of sludge, 900 parts of water, wherein the sludge is municipal sludge, and the moisture content of the sludge is 65% .

[0032] The production steps are as follows:

[0033] (1) Weigh the components according to the weight ratio;

[0034] (2) injecting dodecylbenzene sulfonic acid, sodium hydroxide, sodium ethoxylated alkyl sulfate and water into a foaming machine for foaming to form a foam mixture; wherein in this step, the amount of water used is the total amount of water. 1 / 3 of the weight part.

[0035] (3) Put the inorganic fibers, magnesia, cement, sludge and the remaining water into the mixing equipment to fully stir to f...

Embodiment 2

[0039] Example 2: A method for making wallboards by using sludge, the partition wallboard includes the following components in parts by weight: 26 parts of dodecylbenzene sulfonic acid, 4 parts of sodium hydroxide, ethoxylated 9 parts of sodium alkyl sulfate, 10 parts of inorganic fibers, 25 parts of magnesia, 250 parts of cement, 550 parts of sludge, and 850 parts of water, wherein the moisture content of the sludge is 70%, and the preparation method is the same as that in Example 1.

[0040]

Embodiment 3

[0041] Embodiment 3: a method for making wallboard by utilizing sludge, the partition wallboard comprises the following components in parts by weight: 30 parts of dodecylbenzene sulfonic acid, 4 parts of sodium hydroxide, ethoxylated 10 parts of sodium alkyl sulfate, 15 parts of inorganic fibers, 30 parts of magnesia, 300 parts of cement, 600 parts of sludge, and 700 parts of water, wherein the moisture content of the sludge is 75%, and the preparation method is the same as that of Example 1.

[0042] like figure 1 As shown, a device for making wall panels from sludge includes a stirring device, a sludge pump 9, a foaming machine 15, a mixing device and a plate making machine 19. The stirring device and the sludge pump 9 feed The port is communicated through the feeding pipe 8, and the discharge port of the sludge pump 9 is communicated with the mixing equipment through the discharging pipe 10; the discharge port of the foaming machine 15 is connected with a jet pump 16, and t...

Abstract

The invention relates to a method and device for manufacturing wallboards through sludge. Each partition wallboard includes, by weight, 23-30 parts of dodecylbenzene sulfonic acid, 3-4 parts of sodium hydroxide, 8-10 parts of ethoxylation sodium alkyl sulfate, 5-15 parts of inorganic fibers, 20-30 parts of magnesite, 200-300 parts of cement, 500-600 parts of the sludge and 800-900 parts of water, wherein the water content of the sludge is above 65%. The method and device for manufacturing the wallboards through the sludge have the advantages that the processing problem of the sludge is effectively solved, environmentally friendliness is achieved, no harm exists, the sludge can be recycled and generate new economic benefits, requirements are low, investment is little, yield is high, and the method and device can be popularized to government departments at all levels or enterprises conveniently.

Description

[0001] technical field [0002] The invention relates to the field of urban sludge treatment, in particular to a method and a device for making wallboards by utilizing sludge. [0003] Background technique [0004] With the development of my country's social economy and urbanization, the production and quantity of urban sewage is increasing. At present, there are more than 427 urban sewage treatment plants in operation nationwide, with an annual treatment capacity of 11.36 billion cubic meters. According to relevant forecasts, the amount of urban sewage in my country will increase significantly in the next two decades. In 2010, the amount of sewage discharged will reach 440×108 m3 / d; in 2020, the amount of sewage discharged will reach 536×108 m3 / d. [0005] Sludge treatment and disposal methods around the world: sanitary landfill, sludge agricultural use, sludge incineration, sludge drying and heat treatment, sludge composting, ocean dumping. [0006] Sanitary landfill, t...
