Description
(一)技术领域(1) Technical field
本实用新型涉及一种沼气发生器，尤其提供了一种由塑料板材压制成型的沼气发生器加气囊式储气装置组成的沼气系统。属于沼气发生器技术领域。The utility model relates to a biogas generator, and in particular provides a biogas system composed of a biogas generator pressed and formed by plastic plates and an air bag type gas storage device.

(二)背景技术(2) Background technology
沼气应用已经普及，目前户用沼气发生器从产气和储气方式分类有浮罩式和水压式两种，从结构形式分类有水泥沼气池加浮罩储气罐、玻璃钢沼气罐加浮罩储气罐、塑料注塑沼气罐加浮罩、塑料压制成型沼气罐加水压间等。经过多年实践，我们发现现有户用沼气系统存在以下问题：1.水压式沼气系统的沼气罐空间利用率低；罐内压力大有“冲盖”现象；沼液在水压间与沼气罐之间受压力运动会降低罐内温度导致产气量降低；产气压力不稳定。2.浮罩式储气罐由于浮罩需要用水密封，冬季上冻后浮罩会被冰冻而失去作用。3.水泥沼气池存在沼气泄漏和使用寿命短的问题。4.玻璃钢沼气罐的造价过高、罐体重、安装不便。The application of biogas has been popularized. At present, household biogas generators are classified into two types: floating cover type and hydraulic type in terms of gas production and gas storage methods. In terms of structural forms, there are cement biogas tanks with floating cover gas storage tanks, and fiberglass biogas tanks with floating covers. Cover gas storage tank, plastic injection molded biogas tank plus floating cover, plastic pressed molding biogas tank plus water pressure room, etc. After years of practice, we found the following problems in the existing household biogas system: 1. The space utilization rate of the biogas tank in the hydraulic biogas system is low; The pressure movement between the tanks will reduce the temperature in the tanks, resulting in a decrease in the gas production; the gas production pressure is unstable. 2. Since the floating cover needs to be sealed with water, the floating cover will be frozen and lose its function after freezing in winter. 3. The cement biogas digester has the problems of biogas leakage and short service life. 4. The cost of the FRP biogas tank is too high, the tank is heavy, and the installation is inconvenient.

(五)具体实施方式(5) Specific implementation methods
以下具体实施方式用于说明本实用新型，但不用来限制本实用新型的范围。The following specific embodiments are used to illustrate the utility model, but are not used to limit the scope of the utility model.
图1中沼气发生器1塑料板材压制成型沼气发生器，由上下两个半球体或半椭圆组成，两半球体之间用胶粘接再用螺栓紧固，沼气发生器配备进出料管口分别与进料池4和出料池5连接，沼气发生器配备出气口，通过产气管道与凝水器6的入口连接；凝水器6的出口通过产气管道与单向阀7的入口连接，单向阀7的出口通过产气管道与气囊式储气装置2的入口连接，气囊式储气装置2的出口通过用气管道与脱硫器8的入口连接，脱硫器8的出口通过产气管道与用气阀门9的入口连接。The biogas generator 1 in Fig. 1 is pressed and molded by plastic sheet.

Pipeline is connected with the inlet of gas valve 9.
本实用新型解决其技术问题实现其有益效果的主要步骤如下：The utility model solves its technical problem and realizes the main steps of its beneficial effect as follows:
制取沼气：将用于制取沼气的原料和水倒入进料池4，经进料管口流入沼气发生器1，制取沼气的原料经过罐内发酵后产生沼气，管内压力升高，由于沼气发生器内的液位高于进出料口，罐内的沼气受压沿产气管道输送到凝水器6，凝水器6的作用是吸收沼气中的水分，避免管道受阻，沼气通过凝水器6输送到单向阀7，单向阀7用于限制沼气只能自沼气发生器向储气装置流动，从而保证沼气发生器内的压力稳定，沼气通过单向阀7沿输气管道送入气囊式储气装置2，由于沼气不断产生，气囊式储气装置2内的压力逐渐升高，体积增大，将气囊配重3顶起。Biogas production: Pour the raw materials and water used for biogas production into the feed tank 4, and flow into the biogas generator 1 through the feed pipe mouth. The raw materials for biogas production are fermented in the tank to produce biogas, and the pressure in the pipe increases. Since the liquid level in the biogas generator is higher than the inlet and outlet, the biogas in the tank is transported to the water condenser 6 along the gas production pipeline under pressure. The water condenser 6 is sent to the one-way valve 7, which is used to limit the flow of biogas from the biogas generator to the gas storage device, so as to ensure that the pressure in the biogas generator is stable, and the biogas passes through the one-way valve 7 along the gas transmission line. The pipeline is sent into the air bag type gas storage device 2, and due to the continuous generation of biogas, the pressure in the air bag type gas storage device 2 gradually increases, and the volume increases, and the air bag counterweight 3 is jacked up.
使用沼气：气囊式储气装置2内的沼气在气囊配重3的压力下被压入用气管道输送到脱硫器8，脱硫器8吸收沼气中的硫化氢成分，当用户打开用气阀门9时，沼气就可以输送到用户的用气灶具。Use of biogas: The biogas in the air bag type gas storage device 2 is pressed into the gas pipeline under the pressure of the air bag counterweight 3 and transported to the desulfurizer 8. The desulfurizer 8 absorbs the hydrogen sulfide in the biogas. When the user opens the gas valve 9 , the biogas can be transported to the user's gas cooker.
排沼液：本系统在产生沼气的同时沼气发生器1内的压力会将部分沼液排到出料池5中，用户可以根据需要清楚出料池5中沼液。Biogas slurry discharge: when the system generates biogas, the pressure inside the biogas generator 1 will discharge part of the biogas slurry into the discharge pond 5, and the user can clear the biogas slurry in the discharge pond 5 as needed.
排沼渣：将小型水泵的管道插入沼气发生器1的底部可以抽出罐内的沼渣。Biogas residue discharge: Insert the pipe of the small water pump into the bottom of the biogas generator 1 to extract the biogas residue in the tank.
