Abstract

The utility model discloses a device that recycles the sewage water heat (see attached pictures), comprising a heat transfer device (1), a shell (2) and a separation plate (3). The heat transfer device (1) is helical structured; the shell (2) is arranged with a sewage outlet hole (b) and the separation plate (3) with a sewage inlet hole (a). The device can be positioned at the outlet of the boiler water tank so as to try not to change the original device, or at the pipe before the inlet pf the boiler feed pump; the device can serve as an anti-slip water-containing plate in the bathroom, at this time, the sewage from bathing exchanges heat with flowing cold water in the heat transfer device (1) in the water-containing plate. The utility model has low cost, simple manufacturing technique and good energy saving effect.

Description

A kind of heat reclaim unit

Technical field:

The utility model is a kind of heat reclaim unit.Particularly relate to a kind of device that reclaims the sewer heat.

Background technology:

Energy savings, the protection environment has caused the very big concern of countries in the world.And in our live and work, there are many places can be by the energy savings of taking measures.As boiler is the rich and influential family who wastes energy, particularly medium small boiler, and its thermal efficiency is general on the low side in 65%.Boiler waste energy all multifactor in, wherein one is the heat that boiler blowdown water is taken out of, its share reaches more than 5%; Also have people when having a bath, all contain the callable energy when hot water is drained.The waste of the energy not only influences economic benefit of enterprises, increases individual's expenditure, more has influence on the long-run development of country, has influence on environmental protection.

Summary of the invention and technical scheme:

The purpose of this utility model is the problem at above-mentioned existence, and a kind of device that reclaims the sewer heat is provided.

Scheme of the present utility model is such: with sewer by cutoff board [3] constitute with spiral bending tube arrange every chute, the spiral bending tube heat-exchanger rig [1] that enters with cold water carries out heat exchange, improves cold water temperature, thereby reaches the purpose that reclaims heat.

During work, sewer enters by the inlet opening a on the end cutoff board [3] of heat-exchanger rig [1], through discharging from other end cutoff board [3] after the heat exchange every chute bottom apopore b, and cold water enters from the opposite end of spiral bending tube, flow in spiral bending tube, its flow direction is opposite with sewer flow direction in chute.The heat of sewer passes to cold water by the spiral metal bend pipe, and like this, the cold water water temperature that flows out from the utility model is improved, and reaches energy-conservation purpose.

Cutoff board [3] be the counter flow action of reinforced platoon's sewage and cold water every the chute effect, improve heat exchange efficiency.

The utility model cost is low, manufacturing is simple, and good energy-conserving effect has favorable economic benefit and social benefit.

Accompanying drawing is a structural map of the present utility model.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

In the accompanying drawing, to be rectangle housing, [3] cutoff board constitute airtightly every chute for arranging with spiral bending tube for [1] spiral bending tube heat-exchanger rig, [2], and housing [2] has apopore b every the chute bottom, and cutoff board [3] has inlet opening a.

During work, the sewer that has heat enters by the inlet opening a on the cutoff board [3], airtight between chute, flowing, and cold water enters from spiral bending tube heat-exchanger rig [1] one end, its flow direction is opposite with the sewer flow direction, and by the effect of cutoff board [3], sewer and cold water carry out the counterflow exchange heat, discharge from the other end of spiral bending tube through inhaling the cold water that heat is arranged after the heat exchange, cooled sewer then flows out by the apopore b that housing [2] is gone up every the chute bottom.Like this, the cold water water temperature that flows out from the utility model is improved, and reaches energy-conservation purpose.

The utility model can be installed in the exit position of boiler feedwater case, not change existing facility as far as possible, also can be connected on the preceding pipeline of boiler feedwater pump intake; When using, can be used as the drip tray of anti-skidding usefulness in the bathroom, at this moment, the sewage that bathing is got off, in drip tray with flowing cold water heat-shift in the spiral bending tube heat-exchanger rig [1].

Claims

1, a kind of heat reclaim unit, it is characterized in that a rectangle housing [2], housing [2] bottom is equipped with closed cutoff board [3], and spiral bending tube heat-exchanger rig [1] is installed in the cutoff board [3], cutoff board has inlet opening a on [3], housing [2] have apopore b every chute bottom.
