Problems solved by technology

[0004] The heating methods of the anaerobic reactor mainly include: ① direct heating of the steam in the anaerobic reactor, which has the advantage of simple equipment, but it is easy to cause local overheating of the sludge, which will affect the normal activities of anaerobic microorganisms, and the direct introduction of steam into the tank will cause Increase the moisture content of the sludge; ②External heating of the anaerobic reactor: Preheat the sludge entering the anaerobic reactor before feeding it into the anaerobic reactor. The amount of sludge required for preheating is small and easy to control ;When the preheating temperature is higher, it is beneficial to kill insect eggs and will not be harmful to anaerobic microorganisms; but the equipment for anaerobic reactor heating is more complicated

Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] The reference signs in the accompanying drawings of the specification include:

[0023] Steam pipe 11, flange 12, middle pool roof 13, waterproof wing ring 14, casing 15, exhaust hole 16, paddle 17.

[0024] Such as figure 1 The shown anaerobic reaction heater includes an intermediate pool and an intermediate pool roof 13 covered on the intermediate pool, the middle of the middle pool roof 13 is provided with a steam pipe 11, and the outer side of the upper part of the steam pipe 11 is sleeved with a sleeve 15. The steam pipe 11 is connected to the casing 15 through a flange 12. The flange 12 includes an upper flange 12 and a lower flange 12. The lower flange 12 is fixedly installed on the upper end of the casing 15. The steam pipe above the casing 15 11 upper flange 12 that is fixedly installed and matched with lower flange 12. A...

Abstract

The invention belongs to the technical field of sewage treatment, and relates to an anaerobic reaction heater and a heating method thereof. The anaerobic reaction heater comprises a middle tank and amiddle tank top plate covering the middle tank, wherein a steam pipe is arranged in the middle of the middle tank top plate in a penetrating manner, a sleeve sleeves the steam pipe, the steam pipe isdetachably connected with the sleeve, the lower part of the sleeve extends below the liquid level in a heating tank, and a lot of vent holes are formed in the steam pipe. The anaerobic reaction heaterand the heating method thereof effectively solve the problem that biogas production is affected due to abnormal anaerobic reaction caused by the fact that outdoor environment temperature in winter isbelow 0 DEG C for a long time in the north of China.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to an anaerobic reaction heater and a heating method thereof. Background technique [0002] At present, the more commonly used high-efficiency anaerobic treatment systems include upflow anaerobic sludge bed (UASB), anaerobic sequencing batch reactor (ASBR), anaerobic baffle reactor (ABR) and expanded granular sludge bed. (EGSB) and others. Among them, UASB has been widely used at home and abroad because of its advantages of good treatment effect and stable operation. [0003] The use of anaerobic treatment technology to treat landfill leachate has a relatively wide range of applications at home and abroad, and the most important factor affecting the external environment of anaerobic treatment operation is the change in operating temperature brought about by climate change. The temperature of the anaerobic reactor should be properly controlled at 30-33°C. Due to the long wi...
