Abstract

The invention relates to municipal waste disposal, in particular to a comprehensive municipal waste disposing and recycling and brick preparing process. The process comprises the following steps of: with construction waste and domestic waste as main raw materials, screening by classifying, crushing and secondarily screening; proportioning by using 30-70% construction waste particles and domestic waste particles; adding water to mix and stir; then feeding into a brick making machine to make blanks; drying; and finally, burning to form bricks. By using the comprehensive municipal waste disposing and recycling and brick preparing process provided by the invention, the disposal problem of municipal construction waste and domestic waste is solved through waste utilization; and comprehensive municipal waste is used as the raw material, therefore, energy sources are saved for a brick making process, the resource consumption is reduced, and the transportation cost is reduced.

Description

City integrated refuse treatment and recovery brickmaking technology

One, technical field:

The present invention is a kind of treatment of urban garbage, particularly a kind of city integrated refuse treatment and recovery brickmaking technology.

Two, background technology:

Along with socio-economic development, social progress, urbanization process is accelerated, and urban population is more and more; Urban construction is also maked rapid progress, yet has also produced a large amount of domestic refuses simultaneously, and in addition, the urbanization construction has also caused a large amount of building wastes; Common processing mode is mainly buried, though China advocates waste reclaimation, and save energy, the processing mode of domestic refuse still allows of no optimist at present; A large amount of soils is occupied topples over and buries, even directly air storage, causes very big pollution to environment, even buried; Because rubbish contains a lot of non-degradable compositions, long-term land occupation, and pollute to underground water, influence people's healthy living.

In China's brickmaking technology, be main mainly, consumed a large amount of land resources for a long time with clay; Taken a large amount of arable lands, be save energy, country calls energy-conservation brickmaking; Employing is main with clay, and a large amount of low combustion value coal gangues that the colliery produces had so both satisfied combustiblematerials requirement in the clay as composition; Again coal gangue is recycled, practiced thrift clay resource; Because domestic refuse itself contains a large amount of combustiblesubstances; So someone expects with clay and domestic refuse as brick-making raw material; Both solved the consumption of clay data, and also can handle the processing of municipal wastes, but another problem need be transported to two kinds of raw materials together; This will produce very big transportation cost, be unfavorable for that refuse treatment reclaims brick-making technology and apply.

Three, summary of the invention:

The objective of the invention is to overcome the weak point of prior art, a kind of energy-conserving and environment-protective are provided, city integrated refuse treatment that cost is low and recovery brickmaking technology.

Technical scheme:

A kind of city integrated refuse treatment and recovery brickmaking technology are main raw material with building waste and domestic refuse, through category filter, pulverizing, postsearch screening; By weight percentage; By 30～70% building waste powders and 30～70% domestic refuse powders batching, add water and mix stirring, send into the brick press base then; Dry, be fired into brick at last.

When described building waste excavated soil property for the urban construction roadbed, building waste powder consumption was 50～60%, and domestic refuse powder consumption is 40～50%.

When described domestic refuse was mud such as water drain, river course, building waste powder consumption was 60～70%, and domestic refuse powder consumption is 30～40%.

Described building waste adopts screening to pulverize all-in-one, obtains the powder below the 1cm, and domestic refuse is ground into the particle below the 1cm with kibbler after compression.

Beneficial effect of the present invention:

1, city integrated refuse treatment of the present invention and recovery brickmaking technology, utilization of waste material solves urban architecture rubbish and domestic rubbish disposal problem.

2, city integrated refuse treatment of the present invention and recovery brickmaking technology, adopting city integrated rubbish is raw material, save energy on brick-making technology reduces resource consumption, has reduced transportation cost, nearby brickmaking.

3, city integrated refuse treatment of the present invention and recovery brickmaking technology, utilization of waste material has reduced environmental pollution, has reduced the problems such as groundwater pollution that cause of burying.

Four, description of drawings:

Fig. 1 is the city integrated refuse treatment of the present invention and reclaims the brickmaking technology synoptic diagram.

Five, embodiment:

Embodiment one: referring to Fig. 1, a kind of city integrated refuse treatment and recovery brickmaking technology are main raw material with building waste and domestic refuse; Through category filter, pulverizing, postsearch screening, by 60% building waste powder and 40% domestic refuse powder batching, building waste excavates soil property for the urban construction roadbed; Add water and mix stirring in right amount; Send into the brick press base then, dry, be fired into brick at last.

Building waste adopts screening to pulverize all-in-one, obtains the powder below the 1cm, and domestic refuse is ground into the particle below the 1cm with kibbler after compression

Embodiment two: referring to Fig. 1, embodiment and embodiment one are basic identical, and something in common is not being given unnecessary details, and different places are that when domestic refuse was mud such as water drain, river course, building waste powder consumption was 70%, and domestic refuse powder consumption is 30%.

Claims

1. a city integrated refuse treatment and reclaim brickmaking technology; It is characterized in that: with building waste and domestic refuse is main raw material, through category filter, pulverizing, postsearch screening, by 30～70% building waste powders and 30～70% domestic refuse powders batching; Add water and mix stirring; Send into the brick press base then, dry, be fired into brick at last.

2. city integrated refuse treatment according to claim 1 and recovery brickmaking technology is characterized in that: when described building waste excavated soil property for the urban construction roadbed, building waste powder consumption was 50～60%, and domestic refuse powder consumption is 40～50%.

3. city integrated refuse treatment according to claim 2 and reclaim brickmaking technology is characterized in that: when described domestic refuse was mud such as water drain, river course, building waste powder consumption was 60～70%, and domestic refuse powder consumption is 30～40%.

4. city integrated refuse treatment according to claim 1 and recovery brickmaking technology is characterized in that: described building waste adopts screening to pulverize all-in-one, obtains the powder below the 1cm, and domestic refuse is ground into the particle below the 1cm with kibbler after compression.
