Description

Containerized anaerobic reaction chamber

technical field

The utility model belongs to anaerobic biogas fermentation equipment, in particular to a container-type anaerobic reaction chamber.

Background technique

The anaerobic biogas fermentation method adopts more biological treatment methods of livestock and poultry manure. Anaerobic biogas fermentation equipment generally uses underground or semi-underground fermentation tanks as reaction chambers, equipped with agitators and pipelines, and is suitable for wet manure with water flushing. Sewage treatment. When in use, the submersible sewage pump is used to transport the high-water fecal liquid to the fermentation tank through the pipeline. According to the biogas output after fermentation, the fecal liquid is replenished on time, and the fermentation residue biogas liquid is discharged at the same time, and the biogas liquid is processed. Dehydration treatment. The disadvantages of this method are: the processing and installation of the fermentation tank is very time-consuming and labor-intensive; wet fermentation consumes a lot of water, discharges a large amount of sewage, and requires sewage treatment, which increases the operation and production costs; wet biogas has high sulfur content, The quality of biogas is poor, and the gas output rate of fermentation products is low; there are agitators and pipelines in the fermentation tank, which are prone to malfunction due to the influence of interfering substances (such as plastics, wood blocks, sand, etc.) in the fecal liquid; energy consumption in winter in cold northern regions high. It can be seen that this traditional fermentation device has the problems of high energy consumption, poor reliability, poor biogas quality, low gas output rate, and high production cost.

Utility model content

The purpose of the utility model is to solve the above problems and provide a container-type anaerobic reaction chamber with low energy consumption, high reliability, high biogas quality, high gas output rate and low production cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the container-type anaerobic reaction chamber of the utility model includes a reaction chamber, a thermal insulation layer and a biogas slurry return system. The body of the reaction chamber is an abandoned container, and a biogas outlet pipe and an exhaust gas outlet pipe are arranged on the upper top plate of the abandoned container. Two thermometers are installed on the side of the abandoned container, and a sealed door is arranged on the end surface of the abandoned container.

As an improvement of the utility model, the biogas slurry return system is composed of a thermometer, an overflow tank, a return tank, a liquid collection tank, a liquid level valve, a water supply pipe, a submersible sewage pump, a spray infusion pipe, and a nozzle. It is installed obliquely at the bottom of the reaction chamber and communicated with the backflow tank. The liquid collection tank is divided into a pre-filtration cavity and a post-filtration cavity by a vertical filter plate. The backflow tank is connected to the pre-filtration cavity of the liquid collection tank. Unicom, before the filter cavity is installed a thermometer, liquid level valve, water supply pipe, after the filter cavity is installed a submersible sewage pump, one end of the spray infusion tube is connected to the outlet of the submersible sewage pump, and the other end is extended horizontally and installed in the On the inner top of the reaction chamber, nozzles are evenly distributed on the inner section of the reaction chamber of the spray infusion pipe.

After adopting the above technical scheme, the beneficial effects of the container-type anaerobic reaction chamber provided by the utility model are:

1. Low self-energy consumption, only consumes 10% to 15% of the energy generated by itself in winter. Tests show that energy consumption can be saved by 30% to 50% compared with traditional fermentation devices.

2. High reliability. Since there are no agitators and pipelines, the fermentation is not affected by interfering substances (such as plastics, wood blocks, sand, etc.), so it does not need to spend manpower and equipment to detect them before fermentation, which improves the reliability of the system.

3. The quality of biogas is high, and the rate of gas output of fermentation products is high. The sulfur content is far lower than that of wet biogas, only 50-300ppm, and can be directly used by biogas engines without scrubbing.

4. Low production cost. Because the fermentation residue has no biogas slurry from wet fermentation, it does not need dehydration treatment. The fermentation residue can be used as garden fertilizer or crop fertilizer after simple sieving and short-term composting, so the storage and post-processing costs are low and the value is high. ;Using the biogas slurry backflow technology, the water consumption is greatly reduced compared with the wet method, and there is almost no sewage discharge, which greatly saves water and sewage treatment fees; the use of discarded containers as reaction chambers realizes factory production and saves installation and processing costs by 30% , shorten the construction period up to 30 days.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

In Fig. 1, a schematic structural diagram of the container-type anaerobic reaction chamber of the present invention is given, including a reaction chamber 1, an insulation layer 2 and a biogas slurry return system. The body of the reaction chamber 1 is an abandoned container, and a biogas outlet pipe 3 and an exhaust gas outlet pipe 5 are arranged on the upper top plate of the abandoned container. Two thermometers 4 are installed on the side of the abandoned container, and a sealed chamber is arranged on the end surface of the abandoned container. door 6.

As an improvement of the utility model, the biogas slurry return system consists of a thermometer 4, an overflow tank 7, a return tank 8, a liquid collection tank 9, a liquid level valve 10, a water supply pipe 11, a submersible sewage pump 12, a spray infusion pipe 13. The spray head 14 is composed of an overflow tank 7 arranged obliquely at the bottom of the reaction chamber 1 and communicated with the return tank 8. The liquid collection tank 9 is divided into a pre-filtering cavity and a post-filtering cavity by a vertical filter plate , the reflux tank 8 communicates with the pre-filtration cavity of the liquid collection tank 9, the pre-filtration cavity is equipped with a thermometer 4, a liquid level valve 10, and a water supply pipe 11, and a submersible sewage pump 12 is installed in the post-filtration cavity. One end of the infusion pipe 13 is connected with the outlet of the submersible sewage pump 12, and the other end extends horizontally and is installed on the inner top of the reaction chamber 1. The inner section of the reaction chamber 1 of the spray infusion pipe 13 is uniformly provided with nozzles 14.

The working process of the container-type anaerobic reaction chamber is: open the sealed chamber door 6, and put the solid manure with a moisture content lower than 75% into the reaction chamber 1. During the fermentation process, the biogas slurry seeps into the overflow tank 7 and enters the return tank 8, then flow into the liquid collection tank 9 through the pipeline, and the submersible sewage pump 12 outputs the filtered biogas slurry through the spray infusion pipe 13 and sprays and humidifies the nozzle 14 to realize the recycling of the biogas slurry. When the biogas slurry decreases, Water replenishment pipe 11 replenishes water automatically. After the fermentation is completed, all the fermentation residues are cleaned up, because the fermentation residues do not contain biogas slurry from wet fermentation, so no dehydration treatment is required, and the fermentation residues can be used as garden fertilizers or crop fertilizers after simple sieving and short-term composting .
