Description

Biogas waste heat utilization device

technical field

The utility model relates to a warming device, in particular to a large-scale biogas engineering biogas steam-water separation waste heat utilization device.

Background technique

At present, large-scale biogas projects are developing rapidly in my country. In the northern alpine regions, the heat preservation and temperature increase of biogas projects are particularly important. Among them, the heating methods mainly use coal combustion, solar energy, and waste heat from generator sets. The use of coal to increase temperature not only wastes resources but also pollutes the environment. The use of desulfurization and dust removal equipment has high operating costs, and coal is a non-renewable resource. In today's increasingly tense resources, the prospect of using coal to increase temperature is bleak; solar energy It is a clean resource and rich in resources, but solar energy is limited by weather conditions, and it cannot play a good role in rainy days, especially in winter, when the sunshine time is short, it is difficult to achieve the expected effect, so it is necessary to equip a spare set of solar energy when using it. Heating equipment increases investment and is inconvenient to use; using waste heat from power generation can achieve comprehensive utilization of resources, but the heat is limited and cannot meet the requirements of process use. In the mesophilic anaerobic fermentation process, most of the heat in the steam-water separation of biogas is lost in vain.

Contents of the invention

The purpose of this utility model is to overcome the shortcomings of the above-mentioned technologies, and provide a biogas waste heat with compact structure, reasonable design, easy processing, low cost, effective comprehensive utilization of energy, and recovery of heat from the separation of biogas and water. Use the device.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a serpentine pipeline is installed in the casing, one end of which passes through the casing and connects with the biogas inlet flange, and the other end connects with the biogas outlet flange, and the casing The upper part is welded with a cooling water outlet, and the lower part of the shell is conical and equipped with a sewage outlet.

The utility model has the advantages of:

Reasonable design, compact structure, easy processing, low cost, use of biogas heat, no pollution, no need to add new energy, reduce energy waste, improve the comprehensive utilization of resources, not affected by the environment, and high stability.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Detailed ways

Embodiments of the utility model are described in further detail below in conjunction with the accompanying drawings.

As can be seen from Figure 1, the utility model is equipped with a serpentine pipeline 2 in the casing 1, one end of which passes through the casing 1 and connects with the flange of the biogas inlet 3, and the other end connects with the flange of the biogas outlet 4, and the casing 1 The upper part is welded with a cooling water outlet 5, and the lower part of the shell is conical and equipped with a sewage outlet 6.

There is a condensed water outlet 7 at the outlet of the serpentine pipeline 2 .

A cooling water inlet 8 is also installed at the bottom of the casing 1 .

The utility model is equipped with the position and direction of biogas inlet and outlet, cooling water inlet and outlet, condensed water and sewage outlet, and the heat exchange mode inside the utility model. Biogas enters from the biogas inlet, passes internal heat exchange, exits from the biogas outlet, and enters user systems such as cooking or power generation. Condensed water is discharged from the condensed water outlet, and cooling water enters the utility model from the cooling water inlet through the circulating water pump for heat exchange. It is discharged from the cooling water outlet and enters the heat pump unit. A radiator is installed at the other end of the heat pump unit to heat the anaerobic reactor or preheat the material.
